Why does the battery run out quickly on a new smartphone? Why does the battery drain quickly in Android devices and what is the best thing to do in this case?

Has your phone battery died quickly? We will tell you about the reasons and 4 “secret” ways of what to do to restore and charge the battery. The most common of these reasons is the natural aging of the battery, since each of them, depending on the technology used and the quality of production, is designed for 300-1000 recharge cycles.

Why does my phone battery drain quickly?

With each recharge, the battery capacity decreases. If its service life is 300 cycles, then if it is connected to an external power source daily, it will fail within 10 months. The second reason is improper care. If you do not adhere to the recommended charging technology or use a non-original charger, the battery will also quickly fail.

Another reason is unstable network voltage. The fourth reason is the regular decrease in charge below the critical level of 15%. Try to charge your phone before this milestone is reached. This applies to both enabled and disabled devices. The fifth reason is external influences (overheating, hypothermia, mechanical damage).

We have already discussed how to charge the battery if it is completely dead and you need to make an emergency call during an emergency or emergency. Today we’ll talk about restoring and maintaining the functionality of the batteries of smartphones, phones and other mobile devices under normal conditions.

What to do if your phone battery is dead

Method 1: Wipe and clean your mobile phone

After prolonged use, the metal surface of a lithium battery and even the contacts may suffer from oxidation. This may reduce the life and efficiency of the battery. Remove any residue/rust carefully and regularly to ensure clean contact between the battery and the phone.

To do this, carefully wipe the metal contents of the battery and your mobile phone with a suitable cleaning tool. This also improves charging efficiency and battery life.

Method 2: Revive a Dead Battery through Freezing

Lithium reactions in batteries work using a charging process in which positive and negative electrical charges collide with each other. At normal room temperature, the kinetic energy is relatively large, but since the battery is constantly in an active state, electricity leakage may often occur.

At low temperatures, the lithium coating on the battery surface, along with the electrolyte microstructure and interface, will be significantly altered, resulting in a temporary inactive state that minimizes electrical leakage. This extends the life of your phone's battery by allowing it to recharge more cycles.

Wrap the old phone battery in newspaper and wrap it in plastic wrap 2 times. Alternatively, place the battery in a tightly sealed plastic bag, which will prevent it from getting wet.

Place the battery in the freezer and remove it after 3 days.

Remove the packaging and place the battery in a cool place away from direct sunlight for 2 days.

Insert the battery into the phone, but do not turn it on. Instead, connect your phone to a proper charger and let the device charge for 48 hours.

After the device has been charged for 48 hours, turn it on and check the battery level. If successful, this method will restore your previously dead battery.

Method 3: Try charging the battery from the battery

This method is generally effective for mobile phone batteries that have either reached their service life limit or have been left discharged for an extended period of time; so they eventually lose their ability to hold a charge. This can also happen to the phone battery during long distance transport due to long travel times from one country to another.

You will need the following:

9 volt battery.
Wires for connecting to the battery.
Insulating tape for fastening the wire.
The actual phone battery.

The positive and negative terminals on the 9V battery are clearly marked. Identify them and connect the appropriate side of the wire to each one.

Your cell phone battery is also marked with positive and negative terminals. Connect the wires to them (plus to plus, minus to minus, but not vice versa), secure with electrical tape.

Leave the batteries connected for 10 to 60 seconds, or long enough for your cell phone battery to heat up. Monitor the temperature and time.

As soon as the battery becomes hot, disconnect the batteries immediately. DO NOT attempt to fully charge your cell phone battery this way. Place the battery in the mobile device. You may need to fully charge the battery as usual and then try to turn on the phone.

Method 4: A small light bulb can help

Completely discharge the old battery and then fully charge it to activate it.

The purpose of a complete discharge is to achieve complete depletion of the battery for subsequent more complete recharging.

You will need 2 wires, connect them to the positive and negative terminal of your phone battery.

After this, connect the battery to a small 1.5V lamp. Any residual power contained in the battery will be transferred to the lamp until it is completely depleted.

Note: Discharge will be reached when the light goes out completely. This method is not the most efficient, but it works to some extent.

If the battery inside the phone is completely discharged and is not charging, you need to reset the power controller data. Leave the phone without battery for a few hours, it should work. You can also “push” the charge using a “frog”.

Attention! You undertake all actions with your phone battery at your own risk! We share information, but do not provide any guarantees for the restoration of old batteries! Operations to restore the battery should be carried out if it really does not work well - it is better not to experiment with new batteries!

The weak point in Android phones is the battery. But the reason for rapid discharge is not always the storage capacity. The Android platform is a multifunctional system that consumes a lot of resources, and the question of why the battery drains quickly on Android cannot be answered unequivocally. Therefore, you should first identify the cause, and then solve the drive problem.

What is a battery

Every modern phone has a battery consumption graph, in which you can check which applications affect consumption. Battery capacity refers to the time spent providing uninterrupted power to the device, expressed in amperes and hours and calculated by multiplying the time by the current value.

Modern devices use Li-Pol (lithium polymer) and Li-Ion (lithium ion) batteries. And before understanding the reasons for the rapid discharge of the drive, it should be examined visually. During long-term use, the part noticeably swells and in some places has a white or greenish tint (corrosion). You need to get rid of such a battery urgently, as it can damage the microcircuits and permanently damage the phone.

Reasons for rapid battery drain and solutions

Newer smartphone models are equipped with powerful batteries of 2500 – 3200 mAh, but such devices are not available to most users. Therefore, when purchasing a mobile phone on Android, you should know that the battery can run out after 13 – 16 hours of constant use. But for every cause of rapid exhaustion, there is a solution.

GPS and Wifi networks

Connecting to the Internet and using various applications requires a lot of energy, and what should you do if the battery runs out very quickly? There are 2 options to solve the problem here:

use special programs that will detect and disable running applications automatically (for example, Battery Doctor);

disable the GPS, BlueTooth or Wifi location function if this is not currently required.

These “gluttonous” functions “eat up” up to 25% of the battery charge.

Mobile operator network

When the connection is poorly established or the network does not catch, the phone is in constant search, which means the battery is working at full capacity. In this case, you should connect an additional device - an antenna to catch the signal or turn off the phone, using it only when and where communication is available.

Screen Settings

Quite a lot of energy is consumed by all sorts of bells and whistles with the screen, and in order to reduce its consumption you should:

Reduce the brightness in the “Settings”, “Display” section or display the brightness change widget on the desktop for manual adjustment.
Refuse live wallpaper and use a regular static picture.
Disable auto-rotate screen of your mobile device, since the tracking sensor is constantly active.

Such manipulations with the phone will save battery power by another 10%, especially since these functions are generally not needed at all.

Applications in the background

Often, some programs are loaded on the phone automatically, and their work is practically invisible to the average person. Then, to save battery, you need to stop unused applications through the task manager. To do this, in the battery settings you can see which programs consume the most energy.

Automatic synchronization

The function of auto-synchronization of date, time, accounts, as well as auto-update of applications reduces battery charge. To disable it, you need to find in the settings:

“Date and time” and uncheck the word “Automatic”.
“General”, set the position to “Never”, and in “Alerts” disable “Availability of updates” and “Auto-update”.

This is done so that the Google play store does not connect to the Internet again.

Phone settings

Enable the saving mode provided by the smartphone manufacturer, or download a similar application.
Set Airplane mode if calls are not expected or at night.

Using such modes significantly saves battery energy.

Operating system or firmware

A software feature associated with unscrupulous OS or firmware developers for optimizing the phone is also a common problem. That is, a discrepancy between the technical characteristics of the phone and the battery capacity, for example:

a smartphone with a 4-core processor, 3 GB of memory and powerful speakers, and a battery of 1600 - 2000 mAh;
charge control is poorly monitored;
not adapted for batteries with a large number of milliamps.

There is nothing you can do here except reflash the phone again.

2-3 SIM cards

Two or more SIM cards force the phone to be in constant working mode, since one card is the main one, which catches the Internet, makes MMS and uses other advanced features, and the second comes with restrictions and will constantly be searching for a signal. And most importantly, such a phone requires a heavy load.

Misuse

If you use the charge-discharge method, the part will quickly deteriorate due to chemical reactions.
Charge your Android phone only when necessary.
Try to use your original charger, since voltage readings vary even for identical charges.
You should not leave your phone in the sun while charging. This factor has a negative impact on the battery.
Check the battery wear in a timely manner using the AnTuTuBenchmark program and, if necessary, change it, because in a couple of years, showing 100% charge will mean a maximum of 60%.

When using an Android phone, you should understand that the batteries used in modern smartphones are not designed to last forever. To extend the “life” of a mobile device, you need to treat it with care and promptly pay attention to malfunctions in its operation.

The first mobile devices were designed for making calls and sending SMS. But their time has passed, and they have been replaced by “smart” assistants who make our lives easier every day. With their help, we access the Internet, use a navigator, listen to music, book a table in a restaurant, buy tickets to concerts of our favorite artist, read books while getting to work.

This multitasking affects the rate at which your battery drains. Agree, we won’t like it at all if the smartphone turns off exactly at the moment when, for example, we are buying movie tickets.

1. Screen (reduce brightness, remove animated screensavers)

A bright, colorful, juicy smartphone screen is impressive, but you have to pay for all the pleasures. And in this case, we pay by the fact that the battery of our device will discharge much faster. Set the Brightness slider to about halfway up the scale (this can be done by going to Settings). This simple action will not only save battery power, but also take care of our eyes and relieve excess stress.

You can install a special sensor on your smartphone, and the gadget will adapt to the lighting around us, adjusting the brightness of the display, for example, it will increase it if we are in the sun. Yes, such a sensor also consumes battery energy, but this consumption is negligible compared to how much charge a bright display consumes.

The next point is animated screensavers. Yes, they also look impressive, but again we waste a colossal portion of the battery charge. It is better to install dark-colored wallpaper on your display instead of such screensavers (dark pixels do not require power).

In addition to all of the above, try reducing the standby time: this way the smartphone screen will go dark faster if we are not using the device.

2. Sensors (GPS, NFC, vibration signal)

So, constantly working geolocation consumes a lot of battery. We turn it off in the phone settings and turn it on only when necessary. The fact is that a device with GPS turned on constantly checks with the satellite, which entails battery consumption. And you see, we don’t need such a function every hour.

Most modern phones are equipped with an NFC module. It is needed to transmit encrypted information over short distances. For example, for payment (instead of a plastic card). Often this module is not in demand by users. Therefore, we turn it off too.

Let's talk separately about such an addition as a vibration signal or vibration response. You touch the screen, and the device responds with vibration. At first, you can, of course, amuse yourself with such a function, but keep in mind that each touch will discharge your device. After all, to create vibration, a small motor is sewn into the phone, which must also be powered by something. Our advice: to save battery, turn off the vibration response!

3. Applications and widgets

Let's be honest, few of us use all the applications contained in our mobile devices. Conclusion: we delete those that are not in demand. This way we kill two birds with one stone: we both save battery power and increase the speed of the mobile device.

Some of the installed applications work hard even in sleep mode: they send notifications, play sound even in the background. As a result, the battery discharges faster.

Keep in mind that when you uninstall an application, you are simply closing the program from the recent menu. There is a special program that helps close all applications at once. It's called Super task killer. This action removes unused applications from the phone's memory. If you need one of them, find it and it will start loading again.

If you don't want to search for and install the said Super task killer program, we have good news for you: most mobile devices are natively equipped with a function to close unused applications. To do this, go to “Settings”, look for the “Applications” item, select the service that you want to close. Click on the “Forced stop” item. The phone may warn you that your actions will result in the application not working properly, despite this, click “Ok”. We repeat the described steps for all applications that we decide to close.

4. Mobile communications, Internet, Wi-Fi

When leaving the walls of your home, do not forget to turn off Wi-Fi. If you leave this module running, your mobile device will constantly try to find a network to connect to. And this entails battery consumption.

The same applies to data transfer. If you are on the road and the network is interrupted, it is better to turn off the Internet altogether (most likely, you will not be able to use it well anyway). The fact is that the antenna of the mobile device will constantly search and try to maintain the signal. The more connections and disconnections occur, the faster the device will discharge.

Let's also focus on high-speed Internet. The new generation of 4G connections is really fast. But not all mobile operators have 4G coverage. If your smartphone has a similar network connection installed by default, and you are in a 3G coverage area, for example, then your smartphone will constantly look for the default 4G. Such a search shortens the life of the device.

5. Preservation of the battery itself

Modern mobile phones use lithium batteries. Their service life varies from 1 year to 3 years (depending on the quality of operation). If the battery life is exhausted, it will run out within a few hours. And there’s nothing you can do about it; you’ll have to buy a new battery. Be aware that even with proper use, a new battery will lose up to 30% of its initial capacity in the first year of operation. Often the battery needs to be replaced due to swelling, mechanical damage or overheating. The use of such devices is strictly prohibited! They can damage the device itself. Such batteries are often found in Chinese mobile devices, especially in counterfeits of well-known brands. And some models are initially equipped with a low-capacity battery. Therefore, when you come to the store to buy a new smartphone, carefully study its technical characteristics and consult with the seller. Unfortunately, it is simply impossible to artificially extend the life of a battery.

6. Applications to extend the life of your phone

Opinions about such applications are twofold, let’s say right away. Some experts argue that such assistants can really optimize the performance of your mobile device. They can be found in the Google Play store and are completely free. Let's talk about a few of them.

Smart Quick Settings is a free application aimed at optimizing the performance of your mobile device;
Super task killer free is a program that can close all applications with one touch.

Some experts argue that such programs do more harm than good and should not be trusted, and it is better to perform all operations to optimize the operation of your mobile device manually.

In conclusion, let's say that manufacturers of modern smartphones have already equipped them with an energy saving mode. It automatically adjusts all device settings so that the battery charge is maintained for as long as possible.

Try to treat your phone with care: do not drop it or break it. Such breakdowns and damage lead to problems in its operation as a whole.

Winter is ahead, we are all insulating ourselves, but we can’t insulate our gadgets. Meanwhile, most of them are not adapted to sudden temperature changes. So during the cold season, while outside, try not to use your mobile device. Be patient until you get to your home, office, or at least public transport.

If old phones could boast of three to four days of battery life, then it is impossible to expect this from modern smartphones. Their batteries discharge very quickly, which depends on many factors. Why does my phone run out quickly? Let's try to understand the reasons for this behavior and find out how to increase battery life.

Why does my phone run out quickly?

Have you bought a new gadget, but after a while you start noticing problems with the battery? Why does my phone battery drain so quickly? This may be due to loss of battery capacity. In theory, it should withstand up to 1000 charge-discharge cycles, but in reality the batteries last even less.

If the phone is still under warranty, contact your place of purchase. If the warranty has expired, you should buy a new battery - the problem should disappear. Does your phone get hot and drain quickly? The reason for the loss of charge lies in the installed software.

Some applications put a serious strain on the battery, causing the battery to drain right before your eyes. Skype for Android has these properties - it can drain the battery in just a day, just working in the background. Therefore, you need to identify and delete such applications, or unload them from memory when no longer needed.

As for heating, it is associated with the load placed on the device’s processor. In order to reduce the load, you should use the Clean Master application, which can “kill” tasks hanging in the memory and draining the battery.

If your phone starts to discharge quickly, follow these steps:

Unload unused applications or delete them;
Disable auto-update and synchronization - data transfer consumes a large amount of electricity;
Turn off location detection - it can drain the battery in just a few hours (with intensive use of GPS and GLONASS);
Reduce display brightness;
Stop the habit of checking your phone every two minutes.

By following these helpful tips, you can increase the battery life of your device.

There are two more ways to increase battery life - buy an external battery or choose a smartphone with a high-capacity battery (like Highscreen Boost 2).

The phone charges quickly and discharges quickly

If your phone charges quickly and discharges quickly, then the problem is most likely the battery. This behavior is typical for batteries that have lost their service life. There is only one way out - buy a new battery and replace it. Does your device have a non-removable battery? Then you need to contact the nearest service center and ask specialists to replace the battery.

In some cases, too fast a charge and a fast discharge are associated with a breakdown of the electronic part of the device. If you followed all the recommendations, but they did not help you, take the phone to the nearest service center, where it will be diagnosed. Service specialists will check the functionality of the charging circuit, perform all the necessary repair work and return you to a fully functional phone.

Why does my Android phone discharge quickly and charge too quickly? Sometimes this happens due to a battery calibration failure - it needs to be calibrated again. The Battery Calibration app will do the best job for this task. It requires root rights to work, so you will have to sacrifice the guarantee. We have already written about how to work with the application in our reviews - use the search function.

The phone takes a long time to charge and discharges quickly

If you have problems with charging too long and discharging too quickly, you need to do the following:

Check the condition of the battery;
Remove software responsible for saving battery power;
Contact the service center to test the device.

The reason for too rapid discharge can be found in the applications– try to remember when the problems started and uninstall the software that was installed in recent days.

Samsung phone battery drains quickly

Why does my Samsung Galaxy phone discharge quickly? Actually, we have already reviewed all the ways to solve the problem of rapid battery drain. Samsung phones are not much different from competitors' products, so you should try all the recommendations from our review - some of them will definitely give a positive result.

Also, in some phones from Samsung, as well as from other manufacturers, there is a clear imbalance between the power of the hardware and the battery capacity. As a result, the batteries suffer from excessive stress, discharging right before our eyes.

The phone gets hot and discharges quickly

If the phone gets noticeably warm during operation, this indicates that the processor is busy. And an overloaded processor quickly drains the battery. You need to find out what is the root cause of the overload. To do this, follow these steps:

Reboot your phone;
Clean it with the Clean Master application;
Uninstall recently installed applications.

Follow these recommendations sequentially and observe the device's reaction - as soon as the cause is eliminated, the overheating will disappear, and the battery will be able to enjoy long-term battery life. If the recommendations do not help, back up your important data and perform a Hard Reset. Didn't help? Then you need to contact your nearest service center for repairs.

Today there are quite a large number of smartphones on sale that can boast a 4000-5000 mAh battery - versus the usual 2000-2800 mAh. It would seem that this is the solution to the problem! But in reality everything is not so simple. Firstly, in an effort to reduce the thickness of the device, manufacturers are forced to sacrifice a powerful battery, and secondly, the presence of such a powerful battery does not guarantee long-term operation of the smartphone, because this also depends on the firmware settings.

In principle, almost all smartphones can easily withstand daylight if you use them constantly, and some last for 2-3 days and this is an excellent result. But even smartphones with powerful batteries can begin to discharge unexpectedly quickly. What is the reason for this and how to solve the problem?

OS crash

The very first thing that might come to mind is a glitch in the operating system. Nothing in the world is perfect, so it is quite possible that there really was some kind of failure in the system. What needs to be done? That's right, reboot the device. If you don't have a Restart button, turn off your device and turn it on again.

If after a reboot the problem with battery drain goes away, all that remains is to be happy for you.

Application conflicts or battery consumption by application

Some applications may conflict with each other. In some cases, one installed application can become a source of battery waste. Which one exactly?

You need to go to the device settings, select the “Battery” section and here you will see which application consumes the most energy. In our case there are no such sources.

If installed, you can use the application to check battery drain with other applications - there are plenty of them in the Google Play Store.

If you do not have root rights, if you are unable to find out the source of the problems, you will have to uninstall the latest installed applications one by one until you find the source of the increased battery waste.

Why does battery waste occur in this case? Most likely, the application does not go into sleep mode, and in addition, it may constantly use the GPS, processor, etc.

The problem is in the firmware

This will not be a revelation to anyone - some firmware actually has an increased “consumption” of battery power, and users of many devices have encountered this problem. The only solution in this case is to update the firmware, if possible, or roll back to an earlier firmware version in which the battery did not drain quickly.

Now let's talk about how to increase the battery life of your smartphone or tablet.

Disabling communications

Everything is simple here - if you do not use maps, the Internet or listen to music using the Bluetooth function, you need to turn off all these means of communication, as they can significantly drain the battery. Turn them on only when you really need them.

It’s easy to turn off communications using the usual curtain:

If something doesn't work with the curtain, turn off communications through the settings.

Using Airplane Mode

“Airplane mode” allows you to disable all functions that are in one way or another connected with the mobile network and not only - all possible communications are turned off.

“Airplane mode” should be used if you are on an airplane or subway, and also if you do not want to receive calls from anyone.

Using the “2G networks only” mode

You can find this mode in the “Mobile networks” section of your device or under the curtain.

Brightness setting

The higher the screen brightness, the faster the battery drains - hardly anyone knows about this. Accordingly, if possible, use a brightness mode that is comfortable for your eyes and does not drain the battery instantly.

As for auto-brightness adjustment, this is also a very useful function, including for saving energy, but it does not always work correctly, that is, sometimes it increases the brightness, which in turn affects the battery drain.

Reducing display latency

We are talking about the so-called sleep mode, when the display turns off when inactive. The lower the number, the better, but you shouldn’t sacrifice your comfort, so 30 seconds will be enough.

Turn off vibration

Vibration can have a very serious effect on battery drain, so it is better to disable this mode altogether.

Although for some modes, if there is such a need, vibration can be left.

Disable automatic app updates

The Google Play Store has an option to disable automatic app updates, which can drain your battery when connected to a network.

Using dark wallpaper

This method is only suitable for AMOLED screens, since only light pixels are backlit. Accordingly, if you set dark wallpaper, battery drain decreases.
