The battery on the tablet is draining quickly, what should I do? This causes the tablet to run out of power in sleep or standby mode. Video: calibrating the battery using the Battery Calibration program

Among the most popular mobile devices. However, many users encounter a serious problem during operation: for some reason, the tablet quickly discharges after the next charge.

On average, the battery charge lasts for 8-10 hours continuous operation(this parameter depends on technical parameters device, battery capacity and other factors). If the battery life has become significantly shorter, it is important to understand the reasons for what is happening and immediately seek help from service center.

Reasons for rapid discharge of the device

Before deciding what to do if your tablet discharges very quickly (Samsung, Lenovo, Asus and other Android models), you should try to determine the cause of such a malfunction.

The main ones include:

Failure of the battery itself. This happens due to natural wear and tear of the element, as well as as a result of charging the battery using non-original power adapters, which leads to its overheating and overload.
Problems with the power controller. In this case, the tablet computer monitor may show 100% charging, but the indicator does not correspond to reality, which is why the battery quickly discharges. The chip may need to be replaced.
Failure to comply with certain temperature regime when using a gadget (sudden temperature changes, extreme heat or cold).
Acceleration of battery drain due to active communication modules during activation of the device’s “sleep mode”: Bluetooth, Wi-Fi, GPS.
Rapid battery consumption due to incorrect settings operating system. IN standard mode During the operation of the tablet computer, several services can function, which can be disabled to extend its operation. These include:
- updating data by some running applications;
- automatic synchronization data.
Acceleration of battery drain due to activation of unnecessary additional effects: system sounds, static wallpaper and so on.

If you have tried to fix a number of possible problems yourself, but the tablet is not charging, you should seek help from a specialist.

What to do if there are problems with charging

Some owners mobile gadgets are interested in how to charge a tablet without a charger (for example, if it is broken). There are several options:

Use a USB cable. To charge your tablet via USB, you only need a specific cable with a suitable connector and a laptop or desktop computer. Please note: via USB tablet charges somewhat slower than through a wall outlet, since the maximum charging current and PC voltage are lower.
Use a car charger for your tablet computer. This device is equipped with USB and a connector adapted to the car's cigarette lighter.
Follow the advice of “amateurs” (not recommended, information is given for informational purposes only).

If neither usual nor car charging no, like USB cord, you can use the following method:

take any old charger from mobile phone;
cut off the connector for connecting to the phone;
clean the wires by removing the insulation;
remove the battery from the tablet and find the minus and plus on it;
connect the wires to the battery: red to minus, blue to plus;
secure the resulting structure with tape or insulating tape;
connect to an outlet.

If the tablet does not respond to charging at all (does not see it, does not show it), the gadget requires repair.

If the tablet does not turn on, the reasons may be as follows:

The battery was completely discharged, which requires its restoration using special equipment by connecting additional power sources.
Damaged itself charger or it was chosen incorrectly.
It is necessary to clean the connectors of the charger (if the voltage in the network is normal and the charge indicator is on, but the gadget is not charging).
It is necessary to repair a power controller that has failed after a strong impact to the equipment.

Actually, in any cases (an Android tablet charges instantly, but quickly discharges, the battery discharges sharply during charging itself or when sleep mode is activated, and so on), best option- contact a specialized one. The technician will accurately determine the cause of equipment malfunctions, and then promptly eliminate it by changing the battery itself, repairing the power controller, or correctly setting up the operation of the gadget. You should not try to fix technical problems on your own, since in this case the probability of complete equipment failure is about 90-95%.

When lithium-ion batteries from various mobile gadgets (smartphones, tablets) are deeply discharged, they fall into a coma and show a voltage of 0 V. At the same time, they accept a charge in the usual way. That is, you cannot charge them in your device standard charging. What to do in such a situation. In most cases, the tablet’s battery is still alive and you just need to “push” it. This procedure can be easily done at home.

Perhaps the safest and convenient way pushing the battery of a tablet or smartphone at home is using a “frog”. Received this nickname among the people universal charger, which allows you to charge the battery directly, bypassing the tablet.

To do this, you just need to remove the battery from your tablet or smartphone and insert it into the frog. If the battery has wires (most tablets) and not contact pads (smartphones and phones), then you just have to tinker a little with the connection.

There is no point in describing the use of the “frog” here, since in the case of specific model It's better to look at the instructions for it. Let us only note that the charging current in the majority similar devices equal to 200─250 mA. There are “frogs” that work directly from the network, and others from USB.

After the display on the frog shows that the charging process has begun, wait 20-30 minutes. Then you can remove the battery, install it in the tablet and continue charging as normal. Or you can fully charge it in the “frog” itself. This is up to you.

What to do if you don’t have a frog charger. How then to push the battery at home? More on this below.

How to push a tablet battery using an AC adapter

This is a fairly common method that is described on many forums. I wanted to use it to push the battery from my old flip phone Sony Ericsson Z550i. But then I didn’t have the required resistor at hand, and I revived it in another way, which will be described below.

To push the battery of a tablet or smartphone using network block food, you will need:

the power supply itself (voltage is better than 6─12 V);
resistor;
voltage monitoring equipment (multimeter, voltmeter).

The power supply can be taken from the same tablet, router, etc. The power supply from a microdrill is shown below. We are interested in the output parameters marked in red. Voltage 12 V and current 400 mA. This is quite enough to push.

It is better to take the power supply that provides an output voltage of 6-12 volts. Although you can take it more powerfully. For example, from a laptop.

Then you just need to choose a resistor of higher power and resistance. Although overvoltage is not recommended for lithium batteries.
How, in general, do you choose the resistor value? Ohm's law will help us with this. To push the battery, it is recommended to use a current of 50 mA. Then for a power supply with output voltage we have:

I = U / R, which in our case is 0.05 = 12 / R.

We get a resistor resistance of 240 Ohms. Now let's talk about how it all connects. The photo below shows the power supply connector from the micro drill. I didn’t have another one at hand, but in terms of its characteristics it is completely suitable.

On the outside of the connector we have a “minus”, on the inside there is a “plus”.

And in the next photo the patient himself - Sony battery Ericsson Z550i. Like I said, at first I didn't have a resistor and tried to push it away from car battery stupidly direct. Then a tuning resistor was found and the following circuit was assembled.

And here is the patient himself, because of whom all the fuss flared up. The voltage at its terminals was 0.2 V and it did not react in any way to attempts to charge it in the phone with standard charging.

To make it more convenient, I attached the wires to the positive and negative pads of the battery with zip ties.

In the case of a tablet battery, where there are wires, it will be even easier.

The entire assembled system looked like this.

I started charging with a voltage at the battery terminals of 1.3 volts. From the initial 0.2 to 1.3 V, the voltage was raised by passing current from a car battery (read below). During the charging process, I monitored the battery terminals with a multimeter. First, the voltage increased sharply from 1.3 to 2.4 volts within a couple of minutes.

Then the process slowed down and over the next 20 minutes the voltage increased to 3.1 volts. After this, the process completely slowed down. As a result, the voltage increased from 3.1 to 3.6 V (the nominal value of this battery) for 1.5 hours. In principle, you could try to increase the charging current using a trimming resistor. But I didn’t take any risks because I had enough time and the safety of the battery was a priority.

During charging, I was most concerned about the condition of the battery in terms of heating. But the battery did not heat up at all. Her temperature was slightly above room temperature. But the tuning resistor did not get hot enough. I didn’t measure the temperature, but it was impossible to hold my finger on it for more than a second.

After the voltage increased to 3.6 volts, I kept the battery on charge for another 15-20 minutes. Then I disconnected it and inserted it into the phone, which came to life. I already did further charging using the “native” charger directly on the phone. Then I checked the connection to the computer. The phone was identified and I was able to pull out some files, which is what I needed. Additionally, you can read about.

Now about how I tried to revive this battery before assembling this circuit.

Do you want to know how to increase tablet operating time? Read below.

Now almost any tablet computer can boast of mobility and functionality, but it must be said that it will be better if these parameters are available to us for as long as possible without the need to recharge the computer.

Mobility is based on the fact that we will be able to use it for a long time offline mode. In the event that you need to charge your tablet computer every couple of hours, there will be no talk of any mobility, at least not this parameter won't be that impressive anymore. How can you avoid this?
Selecting a tablet
It must be said that there are interesting techniques that will allow you to enjoy using your tablet computer much more. more time. For example, it’s worth starting with the banal - you should approach the choice of the tablet computer itself as best and as responsibly as possible.

It is worth noting that this is not always done as simply as you would like, but a high-quality result will not keep you waiting long. View large number forums and discussions, study the technical characteristics of tablet computers. Pay attention not only to its power, but also to how much it can withstand in a particular operating mode, which will allow you to do it yourself for real quality choice. In addition, the duration of operation of a tablet computer without recharging is indirect evidence of how well the manufacturing company treated its brainchild, as well as the requirements of ordinary buyers.

Reducing backlight power

If you decide to fight a problem, you must fight its cause. What consumes so much energy on a tablet computer that you don’t have enough charge for more or less normal activities, be it reading or chatting with friends? In fact, the screen consumes the most, no matter how trivial it may sound. About 57% of the energy consumed by the entire tablet computer comes from the screen, specifically from the screen backlight. If you can afford to reduce the screen brightness, then do so - this move will allow you to significantly reduce battery consumption. Note that this is the simplest, not requiring third-party intervention, and the most safe way reducing the energy consumption of your tablet computer.

Extra processes

Next, it is necessary to note a method that can rather be called something like a forced measure. The point is that we need to check whether the program we were using has closed completely or is still in working order, just hidden from our eyes. This must be done using the task manager. The procedure is not complicated, and gradually you will be able to figure out which programs you need and which ones you can ignore.

In principle, there is nothing incredible in the development of such an approach. It is very conveniently used by a wide variety of users. It is worth mentioning that there is another way to protect your tablet computer from losing battery power too quickly. It is necessary to turn off all energy consumers, and these are Wi-Fi, 3G, Bluetooth, NFC, GPS and much more. Don't think that this won't help much.

It is this energy that may not be enough for you to be able to use this device throughout the day. Be that as it may, you have already seen that there are quite a lot of subtleties in this matter. You will be happy with the result if you use the capabilities that are at your fingertips.

The high discharge rate of tablet computers from individual manufacturers today has already become the subject of numerous anecdotes and jokes.

Indeed, this is one of the most common problems among tablet and smartphone users. In some cases, devices discharge quickly enough only when they are active use, as expected.

However, sometimes the energy reserve decreases even when the device is completely turned off - this is not normal and indicates that there is a problem with the tablet or its battery.

Why does a switched off tablet discharge?

There are several reasons why the tablet quickly discharges even when turned off. Firstly, it is possible that you do not completely turn off the tablet, but only put it into sleep mode; in this state, it continues to consume a small amount of energy.

Is being decided this problem quite simple - to completely turn off the device, press and hold the corresponding key for a long time (5-10 seconds). Secondly, it is possible that the tablet's battery is draining quickly due to Wi-fi turned on. Despite the fact that manufacturers say that this should not happen and is wrong, many users note that turning off wifi before the tablet completely stops working, it significantly reduces its discharge rate.

Thirdly, such problems can arise due to the operating system and certain types of applications; we will talk about this in more detail below. Well, the last option, the most unpleasant for the tablet owner - problems arise due to technical malfunctions, ranging from bad work battery and ending with breakdowns on the motherboard. In such cases, the only solution is to contact specialists to repair or replace damaged parts.

Tablet battery drains quickly due to software

Quite often on specialized resources, users complain that the tablet ran out of power very quickly after it was installed new version software or a new application. Moreover, problems exist not only with the Android operating system, but also with Windows. Especially often, such problems arise after installing update packs that were released just recently.

The developer companies themselves are aware of this problem and warn in advance that there is no need to rush to install the most latest updates immediately after they were released. An example is the operating system from Microsoft Corporation.

If Windows 7 allowed you to continuously use the tablet for 7 hours, then later update packs led to the fact that now the battery only lasts for 3 hours. It is likely that these problems will be fixed in the future, but for now we can only recommend not using the latest operating system updates until they have been fully tested.

Particularly worth mentioning are the various applications from third-party developers. Very often, it is because of them that the battery on the tablet quickly discharges. A typical example of this would be Skype program, which consumes quite a lot system resources even if you don't actively use it.

A temporary solution to these problems is to install an older Skype versions– 4.2 or disabling the application at times when you do not need it. The same goes for other programs - if you notice that some of the installed applications are consuming too much energy, it is recommended to disable them, provided that you do not need them at all. at the moment.

Nowadays, the tablet has become one of the irreplaceable helpers through life. However, even tablets have their flaws, just like any other electronic invention. In particular, many gadget owners are faced with the fact that over time, devices become outdated, and the battery in tablets runs out too quickly or even becomes unable to charge at all, not responding to the connected power cable. Why does my tablet battery drain quickly? What to do if the same fate befalls the owner of an electronic assistant, and the battery of his gadget suddenly runs out without any warning or does not charge at all? How to charge a battery that is not actually charging and extend the battery life without it happening? Let's try to figure it out together.

Primary sources of the problem

There are actually quite a few reasons for the rapid discharge of a device. First of all, these are various kinds of technical problems associated with the battery itself. For example, there is a possibility of a manufacturing defect, which is quite typical for fakes. It is possible that the tablet battery needs to be calibrated. It also happens that the charge rapidly drops due to the fact that the battery on the tablet is swollen. In such situations, of course, to extend service life and performance device, you should remove the battery and replace it as fallen into disrepair.

However, simply replace the unusable tablet current source directlywithout instructions, without knowing how to get the battery, It won't work. This could end very badly. It's worth thinking about: is it possible to change the battery V at home, extending the performance of the tablet?

Swollen battery

Of course, if the battery is swollen, it can be safely scrapped. A battery that looks like an inflated bag is as harmful as it is unsightly. Trying to charge such a device is, to put it mildly, a bad idea. It will not charge, and may even turn off forever. Therefore, it makes no sense to make any repairs if the battery on the tablet is swollen. It is necessary to change the current source, but it is worth first thinking about why this could happen.

And the reasons for swelling can be very different: factory defects, too long a life of the gadget itself, shorted contacts. How to check the battery: is it swollen or not? When the drive swells, it is very noticeable even without checking: back panel The device will bulge under battery pressure. If tablet users have swollen batteries, I can give them only one piece of advice: don’t do to eliminate defects. In such situations, immediately get the current source is removed from the device and a new one is installed.

Of course you can do it this also happens at homeconditions, but without knowing how to remove the battery from the tablet,Still, it’s worth contacting a specialist for help. To prevent the gadget discharged, but the source did not swell , you need to carefully choose when purchasing, store the device away from moisture and observe the acceptable temperature range for storing the device.

"Push" for batteries

It is possible that the tablet turns off as a result of a deep discharge, and charging the tablet directly seems hardly feasible. The device just won't charge standard method- once the battery is discharged, it is simply impossible to turn on or start the device in the classic way. Although it is realistic in this case, as they say, to push the battery of the electronic assistant. But how to do this? How to push the tablet battery and bring it back to “life” after such a shutdown at home?

Here, owners of Chinese “frogs” can feel lucky. These devices have already gained notoriety during their existence. However, this cannot be said that they are no good: on the contrary, “frogs” are very good for pushing “sleeping” sources. To do this, you need to put the device, which is turned off, on charging in the “frog” - check and make sure that the drive starts charging faster and faster without any threats. After about half an hour, you can remove the charged battery.

Calibration method

A method to eliminate the rapid “eating” of charge can be to calibrate the tablet battery. Many people begin to wonder, how to calibrate the battery? Those who believe that there is no “home” version of such an action are mistaken: in fact, calibration is carried out quite simply with the help of a few alternative ways. For example, on Android devices you can reset the part application data and create new file use.

You can also apply calibration using special offer V Play Market- Battery Calibration, extremely easy to use. How to calibrate the battery? You need to launch the application and follow all the instructions described. At the end of the procedure, we start the device again, and you can safely start checking - in this way we have updated the source, extending its life.

There's another one indeed easy way, how to calibrate the battery.

For this you will need:

1. Turn on your gadget, be it a tablet or a smartphone, and charge it for at least eight hours.
2. After this time, turn off the power to the device.
3. Turn off the device itself and charge it for another hour.
4. Disconnect power.
5. Launch the gadget for two minutes.
6. Turn it off again and charge for an hour.
7. Disconnect the power and restart the device.

After this, the gadget should function as usual again, without consuming as much energy as before.

In conclusion, I would like to say that if the tablet begins to lose its energy reserves too quickly, then this is not a reason to throw the device in the trash, because there is always a way to get rid of this problem.

What to do if the tablet does not charge? Many users face this problem. Lack of charge does not allow you to perform the necessary operations - pay public utilities, get acquainted with latest news, reply to friends in social networks. Let's see what we can do in such an unpleasant situation. Or is it better to immediately take the device to a service center?

Actions when there is no charging at all

What to do if the tablet does not charge? The first thing you need to do is check that the charger is working properly - try connecting it to some other gadget, for example, a smartphone. If the charging process has started, the problem is with your tablet. In this case, it should be sent to a service center, where it will be diagnosed and repaired.

You also need to try another way to check - connect another charger to the tablet. If charging has started, we go to the store for a new charger. Have you tried connecting another charger to your tablet and it started charging? And a supposedly burned-out charger quietly charges another gadget, but does not charge your tablet? Well, this happens. It’s difficult to say what exactly is responsible for this situation – gadgets or chargers. To clear your doubts, you can visit the service center to consult with knowledgeable specialists.

If you decide to purchase a new charger, try to choose an original accessory. For example, if your Samsung tablet does not charge, buy a branded charger from Samsung - you will receive a six-month warranty and high-quality charger for your tablet.

What to do if charging still doesn’t happen and the battery is deeply discharged? We do not have the opportunity to remove the battery and try to “push” it with an external charger, bypassing the charge control circuit. Therefore, we will proceed in the following way - connect the charger to the tablet and leave it overnight. It is quite possible that the battery will “come to life” overnight and we will have a working device at our disposal.

If the above procedures do not help, feel free to contact the service center. Is your tablet under warranty? Then you can contact the place of purchase - they must accept the smartphone and send it to the service.

The tablet takes a long time to charge - what to do?

There are three reasons for this behavior:

The charge control circuit has failed;
The charger has failed;
The battery has failed.

The first reason can only be fixed at the nearest service center - go there (this is the last resort). But first, let's check the serviceability of the charger - for this we need a known-good charger. Connect it to the tablet and leave it for 2-3 hours. Now check if the battery is full. If it is full, go to the store for a new charger - your old charger is not able to provide sufficient charging current.

There may also be problems with the battery, which does not want to accept a charge. This malfunction can be diagnosed by the nearest service center. But in most cases, the charger is to blame - try replacing it. In addition, if your tablet charges very slowly or does not want to charge at all, remove programs responsible for charge control and battery saving.

Sometimes the reason for the lack of normal charge is applications such as Battery Doctor and CM Security - they contain so-called “trickle” charging modules that can work unstably, interfering with normal battery charging.

The tablet charges quickly and discharges quickly

We already know what to do if the tablet stops charging - we check the charger, test the battery and remove interfering software. But what to do if the tablet starts charging too quickly? If at the same time it discharges just as quickly, then the problem lies in the battery (in most cases).

Since tablet batteries are non-removable, you should contact your nearest service center to replace the battery. In some cases too fast charge may be associated with a breakdown of the tablet's electronic board (charge control circuit). It’s impossible to do anything with it at home, so we feel free to go to a repair shop or return the tablet to a store under warranty.

The tablet is a representative of new technologies. With this portable device you can surf the Internet, read books, chat, spend time and use it as a photo or video camera.

But, like all technology, it is not perfect. All portable devices have their own operating time on a fully charged battery.

For tablets, depending on the battery power and workload level, this period ranges from several hours to five days. Sometimes this happens even faster and indicates problems that need to be solved.

Causes and solutions

The cause of this problem can be various factors, each of which has its own characteristics of elimination.

Technical problems

The likelihood of such malfunctions is very low, but it also happens that the power supply system is in poor condition. The device's battery has its own service life, which includes a certain number of charging cycles. After this period, the part fails or begins to work very poorly. Such troubles can occur due to the use of power adapters that are not suitable for a particular device. In such cases, the equipment is overloaded and its temperature rises. Such problems occur very rarely, but, nevertheless, can cause a rapid discharge.

A battery test using special equipment will help you find out exactly whether this is the reason. If your fears are confirmed, then you need to replace the battery with a new one. It is important to use original components. Spare parts not from an official representative and Chinese copies will be able to solve the problem only for a certain period.

Problems can also occur with the power adapter. The tablet may indicate that it is fully charged, but in fact may not be even half charged. Because of this, the operating time is very short. Solving such a malfunction is extremely difficult; specialists can replace the microcircuit, but this will be expensive and does not guarantee a positive result.

Communications

As is known, data transfer gives high load to the device battery. Therefore, to avoid rapid discharge, you need to turn off:

To do this:

in the settings you need to go to the “communications” menu;
Click the icon on one of them to turn it off/on.

Backlight

Another reason for rapid battery depletion can be the screen backlight. It is this function that consumes about 57% of the charge in any technology. If possible, you should set the minimum or intermediate level backlight. Many tablets have sensors that change the light level automatically. If external lighting does not need to change the screen settings, then this function should be disabled, because it also adds load.

There are also cases when the tablet lies idle and the display lights up. Therefore, you need to install automatic blocking. This will not interfere with video games and browsing the Internet, but when reading books, this function can be disabled.

Adjusting the screen backlight is one of the most simple options battery saving. It does not require special knowledge and tools, but it helps solve such difficulties.

To change the brightness level and time automatic locking, need to:

in the settings find the “screen settings” menu;
adjust the parameters by selecting minimum or average values.

OS setup

Modern tablets have come a long way from the first laptop computers and smartphones, on which you could run your favorite online chat, watch a video and kill time with games. Now gadgets practically live their own lives, making independent trips to the Internet, bringing newer versions of programs from there.

Main actionssystems, which drain the charge, can be considered:

automatic data synchronization;
periodic network polling;
software update.

Automatic data synchronization

All equipment with the Android system loves to verify all data. So, by default, the Google service and other sources are always running, which are not always needed, but always work.

Periodic network polling

The gadget is constantly looking for something on the Internet and “communicating” with someone. , all smartphones, laptops and other gadgets nearby communicate with each other. This activity of devices significantly affects their energy levels. Therefore, it is better to turn off communications or switch them to gentle modes.

For example, if you need Wi-Fi, you can simply turn on the invisibility function. You also need to disable auto search. Modern gadgets are equipped with an optimized Wi-Fi system that controls the activity of the function.

Software updates

Nowadays you can install the most various programs, This:

video games;
media players;
social network clients;
communication applications (Skype, Viber, etc.);
browsers;
area maps;
file exchangers;

Developers of such applications are constantly trying to improve them, which is why they make changes. Signals are also sent by remote servers. The tablet happily downloads all these new things even without the owner’s permission.

This is especially true for devices running Windows OS. They constantly check all programs for updates. This increases the load on the device and its battery. Therefore, you need to turn off automatic updates and monitor the new products yourself. Disable all unnecessary actions operating system is quite simple.

To do this you need:

go to settings;
uncheck the boxes next to the items you want to turn off;

Applications run in the background

An advantage and at the same time a disadvantage modern gadgets can be considered the ability to work several programs together. Of course, you can run the music player and browser at the same time, chatting with friends on social networks and listening to the latest music.

The disadvantage of this feature is that when you launch the second application, the first one continues to work in background, and wastes RAM. This is the function of multitasking. At the same time, background applications are not always useful, and often simply exhaust the device’s resources.

Only when a large number of running applications accumulate, the system automatically closes those that have been turned on for a long time.

The most popular programs that are sitting in the background are:

media players;
e-readers;
video games;
file managers;
various settings.

Developers offer a variety of “tax killers” that will independently close unnecessary things, but, as practice shows, such utilities only reduce the operating time of the gadget. It is better to monitor the power-hungry software yourself. You also need to remove those applications that are rarely used, but appear in the background from time to time.

He divides the programs into three points:

loaded;
executed;

Using the "Stop" button you can remove unnecessary processes. At the same time, this will not harm the operation of the gadget; it is impossible to disable the necessary programs.

OniOSto close background programs, need to:

Double-click the “Home” button to open the task manager;
stop unnecessary processes.

On OSWindows:

to launch the task manager, you need to swipe the sensor from the left side of the screen to the center and back, without lifting your finger;
stop applications.

Additional effects

IN lately Animated wallpapers have gained popularity. Depending on the position of the device, the pattern changes. There are all kinds of options for such effects, including falling snow, a “live” waterfall, and even a car that constantly drives around the display.

It is clear that such interesting things reduce operating time, because they simultaneously load the processor, gyroscope and accelerometer chips. And you can easily do without such wallpaper, because simple images perform this function perfectly.

One of the latest know-how in the field of improving the design of a working device is 3D wallpaper. This, of course, looks nice, but it reduces battery life, so it’s better to change the screensaver to a regular picture or photograph.

To do this:

you need to select an image in the gallery;
Click on the “set as wallpaper” button.

The tablet is draining quickly

The fact that the device discharges very quickly due to powerful games, bright display, etc. – this is understandable. But, there are situations when the gadget loses charge, even if no one touches it.

Standby

When the tablet just sits idle, the charge still disappears. Sometimes up to 50% of the battery drains in one night. The problem is that even without an owner, the gadget is actively looking for new software. Therefore, many programs just need to be disabled.

Of course, such a loss of charge is immediately noticeable. But it’s still worth studying the gadget’s power consumption in different operating modes. This should be stated in the instructions for the equipment and checked using special programs. The cause may also be battery wear.

If it is often completely discharged, or draws excess energy from a powerful outlet, then its performance characteristics drop. This problem can only be solved by purchasing a new original battery.

Off

The battery percentage may drop even when the gadget is turned off.

This happens due to several factors:

not completely switched off state;
Wi-Fi;
operating system;
technical problems.

People quite often, instead of turning off the equipment, simply turn on sleep mode. In this case, it, of course, spends less energy than when it is turned on, but it still spends. Solving this problem is very simple; to turn off the gadget, you need to press the button for 5-10 seconds.

The second reason for discharge may be functioning Wi-Fi. Equipment manufacturers assure that Wi-Fi is not harmful to turned off gadgets and does not affect their charge level in any way. But many tablet owners confirm the opposite. Various programs that feed on the resources of switched off equipment can also cause damage.

The most unpleasant reason for loss of charge can be the breakdown of some parts. This could be battery wear, which was mentioned earlier, or even damage to the motherboard. In these cases, only specialists in repair or replacement of components will help. If the technical condition of the gadget is satisfactory, then solving the discharge problem is very simple by following the above tips. Then the equipment will delight you with reliable and high-quality functionality.

Tablet computers actively fill life modern man. They delight with the bright colors of the screen, smooth lines of shapes, and many useful functions, solving problems, helping and entertaining their owners. But sometimes one problem somewhat overshadows communication with an electronic friend - the tablet’s battery drains quickly. It is especially unpleasant if an alarm signal that the device needs charging finds the owner of the tablet in transport, a store or other public place, in general, far from a power source.

It is clear that problems fast discharge The tablet battery cannot be solved in the ways that help. This requires completely different activities and knowledge.

The reasons that the tablet battery quickly discharges may be hidden, on the one hand, in the type of battery used, its charging modes, storage and operating conditions, on the other hand, in the intensity of use of the tablet and the nature of the functions it performs.

Modern tablet computers use lithium-ion (Li-ion) or lithium polymer (Li-pol) batteries. Unlike older nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries, lithium-ion and lithium-polymer batteries are not subject to the memory effect, which means they are less demanding when it comes to charging. They do not necessarily need to be completely discharged before charging again. Nickel-cadmium and nickel-metal hydride batteries, on the other hand, lose capacity when they are not fully discharged before the next charge cycle (memory effect). Obviously, when choosing a tablet, it is better to choose one with a lithium-ion or lithium-polymer battery. Lithium polymer battery almost 2 times thinner and lighter than lithium-ion (with the same capacity), but at the same time more fragile and much more sensitive to falls, shocks, etc. stress.

When purchasing a tablet equipped with a lithium battery (Li-ion or Li-pol), or a separate lithium battery, you need to pay attention to the release date of the device, since the battery loses about 20% of its capacity per year even without use. If the device has been in storage for about 2 years, it is better to refrain from purchasing it.

Primary sources of the problem

However, simply replace the unusable tablet current source directly without instructions, without knowing how to get the battery, It won't work. This could end very badly. It's worth thinking about: Is it possible to change the battery to extend the performance of the tablet?

Swollen battery

And the reasons for swelling can be very different: factory defects, too long a life of the gadget itself, shorted contacts. How to check the battery: is it swollen or not? When the drive bulges, it is very noticeable even without checking: the back panel of the device will bulge under the pressure of the battery. If tablet users have swollen batteries, I can give them only one piece of advice: don’t do to eliminate defects. In such situations, immediately get the current source is removed from the device and a new one is installed.

"Push" for batteries

It is possible that the tablet turns off as a result of a deep discharge, and charging the tablet directly seems hardly feasible. The device simply does not charge using the standard method - once the battery is discharged, it is simply impossible to turn on or start the device in the classic way. Although it is realistic in this case, as they say, to push the battery of the electronic assistant. But how to do this? How to push the tablet battery and bring it back to “life” after such a shutdown at home?

Calibration method

A method to eliminate the rapid “eating” of charge can be to calibrate the tablet battery. Many people begin to wonder, how to calibrate the battery? Those who believe that there is no “home” option for performing such an action are mistaken: in fact, calibration is carried out quite simply using several alternative methods. For example, on Android devices you can reset the part usage data and create a new usage file.

You can also apply calibration using a special offer in - Battery Calibration, which is extremely easy to use. How to calibrate the battery? You need to launch the application and follow all the instructions described. At the end of the procedure, we start the device again, and you can safely start checking - in this way we have updated the source, extending its life.

There is another really easy way to calibrate the battery.

For this you will need:

After this, the gadget should function as usual again, without consuming as much energy as before.

Modern smartphones and tablets based on the Android operating system provide the user with a huge number of possibilities. But sometimes you cannot use these features due to a dead battery. This problem is especially true if the battery drains too quickly. In this article, we will look at several reasons that lead to this problem, and also offer possible solutions.

Reason No. 1. Wireless technologies.

If your Android smartphone or tablet is draining battery quickly, the first thing to do is check which wireless technologies are enabled and whether they can be disabled. After all, any modern Android has a lot of wireless technologies. For example, Wi-Fi, Bluetooth, GPS and others. All these technologies consume a lot of energy, which is why the Android battery drains quickly. There is only one way to solve this problem - turn off everything that is not used.

To do this, go to the Settings of your Android smartphone. At the very top of the settings screen you will see Wi-Fi switches and Bluetooth. If these wireless technologies If you don’t need them at the moment, you can safely turn them off.

After that, go to the “Location” settings section and turn off GPS navigation there.

If you do not use mobile Internet, then you can turn it off. To do this, open the section called “Settings” and disable the “Data transfer” function there. There you can also change the network type from “LTE” or “3G” to “2G”. This will also give some extra time battery life.

Reason No. 2. Screen backlight.

The screen backlight is another significant energy consumer on your smartphone. If you use the maximum display brightness, the battery of your Android smartphone or tablet will drain very quickly. To fix this, go to settings and go to the “Screen” section. Here you can set the brightness level for the screen backlight. Select the minimum backlight brightness at which you are comfortable working.

Also in the “Screen” settings section, you can set the period after which the device will go into sleep mode. Choose the shortest possible period of time with which you will be comfortable working.

Reason #3: Applications running in the background.

If you have done everything described above, but your battery on your Android smartphone or tablet is still draining quickly, then perhaps your problem is that you have a large number of applications running in the background. To determine which applications are running in the background, first close all applications that you currently have running.

After that, go to the Android settings, to the “Applications” (or “Application Manager”) section and open the “Running” (or “Running”) tab. Here you will see the applications that are currently running. But since you closed all applications in advance, only those applications that are running in the background will be displayed here.

Go through this list of apps and remove any apps you don't use or can live without. There is no point in stopping these applications, since after a while they will start again. The only way to deal with them is by removing them.

Reason No. 4. Old battery.

The battery is not a forever device. The average battery for a smartphone or tablet is designed for only 1 thousand charge and discharge cycles. It is easy to calculate that if you charge your device every day, the battery life will not be enough even for 3 years.

Therefore, if the age of your Android device has exceeded 2 years, then it is likely that the reason for the rapid discharge of the battery is the depletion of its resource. In such a situation, only replacing the old battery with a new one can help. If the battery is removable, then you can do this yourself. Otherwise, you can contact a service center to replace the battery.
