Android standby mode eats up the battery. Everything you need to know about energy saving Android gadgets

Among the owners of smartphones and tablets running Android OS, there are often cases when the battery charge drops sharply on its own. Often this malfunction leads to complete discharge literally in one hour. A similar problem also occurs on devices with other systems, such as iOS, although much less frequently.

There can be many reasons why your Android battery drains quickly. These can be classified as heavy load on the device, and the presence of viruses embedded in Android. Next, we will take a closer look at each of these problems and try to solve them.

Due to its openness and complexity, the Android OS is prone to crashes, and its optimization is at a rather low level. Often included in background it can hold several dozen programs simultaneously. Therefore, even the Android standby mode eats up the battery. This explains why Samsung and any other brand phones quickly discharge.

In addition, most of these applications are not used by the user in any way and waste resources, which means it is worth disabling them.

Viruses

In recent years, the operating room Android system has become highly vulnerable to viruses. Moreover, most of them cannot be detected even by the best antivirus applications.

Under the influence malware The performance of the device drops significantly, and the load on the processor increases. The characteristic features of a phone infection with a virus include:

increased temperature of the device body;
braking;
the appearance of advertising where it should not be.

Defective battery

One of the reasons why the battery's charge quickly drains may be its malfunction. With prolonged use, like any other equipment, it breaks down.

It is quite difficult to avoid such trouble. If you plan to use the same smartphone for, say, three years, then at some point you will have to replace the battery. This is necessary in order to continue to use the device comfortably.

Battery usage rules

Just a few years ago, when buying a new smartphone, sales consultants advised “rocking” the battery - completely discharging and charging it several times in a row.

Now this advice is absolutely useless, since new batteries such as Li-Pol and Li-Ion use other technologies that such “stress” only harms.

It is extremely undesirable to completely discharge the phone, as this leads to a reduction in its lifespan. This occurs due to chemical degradation.
You should charge the device as often as possible.
The best charger you can use is the original one. Even though most phones now have the same connectors, each charger has a slight difference in voltage.
Do not keep your phone charging in direct sunlight. Even such a minor factor will greatly affect the duration of the battery charge.

Ways to extend the operating time of a smartphone on a faulty battery

It is not always possible to charge the device, so if your Android is not eating up the battery as slowly as before, you should slightly adjust the system's operation. What exactly needs to be done and how, we will consider further.

Screen

The screen consumes the most energy, so it's worth setting it up first. The following recommendations should help you:

The higher the brightness, the faster the display drains. Each device has the ability to adjust its settings, so change them to the lowest possible level as soon as possible.
Set the shortest time period for automatic shutdown display. This will prevent you from wasting energy.
When using a device with a screen built on AMOLED technology, you should install dark wallpaper on your desktop, since when displaying black color, practically no energy is wasted.

Communication modules

Communication module components consume power in the background, including when the display is turned off. Constant loading new data produced by them leads to a waste of charge.

Almost all settings related to them are located in the “ Wireless technologies" The name varies depending on the version operating system, but in general it is not very different in each version, so finding them will not be difficult.

There are several ways to optimize this part of the system. Next, we will look at the main ones.

Turn off LTE if you are out of 4G coverage.
Turn off the mobile Internet itself if you at the moment it is not used.
Disable the Wi-Fi search feature if you don't need it at the moment.
Turn off Bluetooth. This technology consumes quite a lot of energy.

Sensors

Modern devices are equipped with a huge number of sensors, due to which the device is discharged in less than an hour. If you deactivate them, the operating time will increase several times.

It's worth disabling:

First of all, stop GPS work. This function is usually placed in the top menu.
The accelerometer and gyroscope are among the most energy-consuming sensors, so automatic screen rotation should be one of the first to be turned off.
Electric motor. This small part is responsible for the vibration response, which drains the battery.
Additionally, you can disable synchronization with cloud services and delete unnecessary accounts.

All this will help to significantly extend the life of the device and make your use of it several times more comfortable.

Battery saving program

To simplify the implementation of all the above actions, it was created large number third party programs. They allow through user-friendly interface choose which functions you currently need, and how the device will save money.

The best among such applications is Battery Doctor. This program is free and available to everyone. It has quite a wide range of functionality, allowing you to optimize settings as flexibly as possible and exercise control over them.

In addition, the program shows the remaining operating time of the device.

Users different models smartphones are faced with the fact that the device begins to catastrophically lose charge. If the device previously lasted 1-2 days, and suddenly does not survive until the evening, it’s time to sound the alarm. It is important to understand why a smartphone discharges quickly and to understand the reasons why the battery runs out. You can take action and the situation will improve.

Why does my phone battery drain quickly?

There are a number of reasons for this problem to arise. Sometimes the battery on your android runs out due to a technical malfunction or breakdown. The user may cause such a difficulty to arise out of ignorance. There are Android applications that waste a lot of energy and drain your gadgets. Frequent use of built-in smartphone functions, automatic detection places can also speed up discharge.

Charges quickly and discharges quickly

The primary source is a battery failure. Over time, it loses its resource and the battery on the android runs out. If it is removable, replace it. If it’s built-in, contact a specialist. Less commonly, the cause is a breakdown in the electronics of the gadget. In the same service center specialists will carry out diagnostics and identify the problem. This will fix the problem with the charging circuit. Less commonly, the reason lies in a battery calibration failure.

Takes a long time to charge and discharges quickly

Make sure the battery is not damaged. If there is no problem with it, then the reason is the applications. Software requires a lot of energy - just get rid of it and the problem will be solved. Low-quality battery-saving software can even worsen the performance of the gadget. If the above reasons are excluded, contact the specialists. It is possible that the battery on your smartphone is dying due to an electronics failure.

Discharges quickly in standby mode

It happens that Android devices die, regardless of the activity of use, if the music and browser are turned off. The reasons may lie in applications that run in the background and drain the battery. Extra energy consumption is caused by turning on the Internet, navigation and similar functions. When the screen is on, pay attention to the brightness: if it is above 75%, then the battery on the phone quickly drains. Live wallpapers also take a toll on your battery life.

New phone runs out of battery quickly

It’s annoying when a brand new Android smartphone pleases you for 8-10 hours and then asks to be connected to a charger. The reason may lie in a manufacturing defect. Some smartphone models initially have a small battery capacity. Why do smartphones run out of charge quickly? Because they come across a non-original product. Fake gadgets are characterized by low quality execution, small battery capacity. Another option is incorrect operating system settings. Try turning on the battery saving function or make the correction yourself.

The phone gets hot and discharges quickly

If the device becomes noticeably warm, this indicates active work processor. Overload leads to a reduction in the life of the device. You need to find the cause of the load on the processor and understand why the gadget freezes. Try restarting the device, clearing the cache yourself or using programs. If this does not help, remove the new software. If all else fails, do it backup data and full reset settings ( Hard Reset).

What to do if your phone runs out quickly

By using simple actions You can reduce processor load and prevent battery drain in standby mode. Try to perform a number of operations to understand why your smartphone discharges quickly. Do this to avoid charging your smartphone every 8 hours:

Screen brightness consumes a lot of power. Install automatic mode, adjust the optimal comfortable brightness within 50-75%.
You should disable the automatic screen rotation feature.
Set sleep mode so that it turns on at the most convenient moment. The smartphone will close on its own background applications, they will not consume energy.
Disable mobile Internet and Wi-Fi, location determination (GPS) and the problem of many Bluetooth smartphones when you are not using them. Functions turned on and waiting significantly drain the device.
Manually disable applications that you are not currently using.
Disable synchronization with your account.
Clear the application cache manually in the settings or using special software.

Which battery saving program is better?

Android apps consume a lot of energy and cause your phone to die. Phone makers are failing to influence this globally. The developers offer a range of high-quality software to save battery. Choose what's convenient for you and enjoy:

Greenify. The software is free and works in offline mode. Designed to reduce energy consumption in rest mode, disable particularly “gluttonous” programs and games. Greenify can even disable processes that are not displayed during manual cleaning.
DU Battery Saver. The program is particularly popular among users - more than 100 million downloads. The software can disable background processes, compile statistics on battery usage. The optimization function identifies and disables energy-consuming processes.
Easy Battery Saver. The application is convenient and interesting. In it you will find a number of rules on what to do if the battery on your smartphone is low. It will not interfere with the operation of the smartphone and eliminates problems in sleep mode. Using the software will not degrade the performance of the phone.

In many modern phones One of the weak points remains the battery. And no wonder. The hardware of smartphones is constantly improving, four- and eight-core processors, large and bright screens, all this requires a lot of energy.

Of course, you can install a capacious battery, but not many manufacturers are doing this yet, because the battery takes up a lot of space and you will have to sacrifice design - making the phone thick :)

Personally, I charge my phone with a 2230 mAh battery every day, it has become a habit. I use the phone often during the day and therefore at the end of the day there is about 20-30% charge left, but you can extend the battery life of the phone and make it work on a single charge for several days.

You can, of course, install one of the applications to save battery power, it is:

makes it easy to save battery

takes up memory
consumes phone resources
consumes phone battery

You can do everything that applications do yourself:

fine tuning for yourself
does not require additional resources
you know what you're doing

you have to go through the settings

I don’t insist that you have to do everything yourself, but for me personally, it’s better when I know what functions I’ve disabled or enabled to save battery; perhaps it will be more convenient for someone to use the application.

1. Display backlight brightness

So the first thing you can do to extend battery life is to lower the screen brightness. And if your phone has a light sensor, then turn it on automatic adjustment. A bright display eats up the battery more than anything else.

Let's go to Settings -> Display -> Brightness and set the desired brightness level

2. Live wallpaper

The second step also concerns the display; to save battery, disable live wallpapers. Live wallpapers are certainly beautiful, but they consume a little energy, although they are useless on their own.

Let's go to Settings -> Display -> Background image and select any photo from the gallery or from background pictures

3. Wireless modules

The next thing you can do is disable wireless modules that you are not currently using - mobile Internet, Wi-Fi, Bluetooth, GPS

Let's go to Settings and disable unnecessary modules, the same can be done from the status bar

4. Using GSM network

If the quality of the mobile network in your region is poor, then you can try disabling LTE and 3G networks. The phone will operate in GSM mode, it is the most economical, but allows you to transfer data at speeds of up to 236 kilobits per second, this should be enough for browsers or for calls, for example

Let's go to Settings -> More -> Mobile network-> Network mode and select the mode GSM only

5. Unnecessary apps

Remove unnecessary apps that are the biggest drain on your battery. To find out which applications are eating up your battery, go to Settings -> Power Options -> Battery Usage, here you will see which applications and services are using battery power.

Conclusion

These tips will help you save battery power on Android when needed. But! They are not required to be used every day, because Android is an operating system that allows

be always in touch using messengers like or Viber
quickly receive information and messages from social networks
track location and attach it to photos
instantly receive email notifications
communicate via Skype

That's why I charge my phone every day and always stay online, instead of 3 days of power saving mode :)

With the problem of discharging too quickly battery(battery) almost all users encounter mobile gadgets. The problem occurs gradually and goes unnoticed for some time, but one day the owner notices that time battery life smartphone or tablet has almost halved. If you do nothing, it will decrease further - until it becomes impossible to use the device. And one day the device won’t turn on at all.

Let's talk about why the battery on Android devices drains quickly and how to extend its life.

Reasons for rapid battery discharge

The actual battery capacity of a smartphone or tablet is lower than indicated in the specifications.
Battery capacity has decreased due to normal wear and tear.
Ambient temperature is below +5 ⁰C or above +30 ⁰C.
Turned on too high level screen brightness.
Resource-intensive features included: GPS, NFC, Bluetooth, etc.
Long distance to base station mobile operator.
Apps and widgets running in the background consume energy.
Frequent turning on and off of the device.
Infection with mobile viruses.
A malfunction of the operating system or hardware, as a result of which certain resource-intensive functions or the device itself are not turned off.

Battery capacity is lower than in the passport

Inconsistency real capacity The battery indicator, which is indicated in the passport of a smartphone or tablet, is more common than you think. It’s just that very few users decide to double-check it. Most believe documents, as well as program indicators, which also do not always display reliable data.

The reason for the discrepancy between actual information and nominal information does not always lie in deception on the part of the manufacturer or seller (although this also occurs); lithium power supplies simply lose their capacity during long-term storage. If you bought a device that was released a year ago, even if proper storage its battery has become less capacious by 2-6%, and when incorrectly charged (that is, when charged to 100%) - by as much as 15-30%.

To calculate the actual capacity of the battery, use charger-discharge devices, like iMAX, or homemade dischargers complete with a multimeter or USB tester. The exact indicators are determined during the discharge of a fully charged battery.

If your phone's battery capacity is less than stated, it will take longer to discharge. short time than expected. And, alas, it is impossible to influence this.

Capacity has decreased over time

Battery wear becomes noticeable after 1.5-2 years of using a smartphone or tablet. But it may happen earlier if:

use the device often and for a long time at low and very high air temperatures (the most favorable temperature for operating lithium batteries is room temperature);
allow discharge close to 0%.
charge the device near heat sources;
store the unused battery at 100% charge at high temperature environment (for storage, the optimal charge level is 40-50% and refrigerator temperature);
charge the battery more high voltage and currents than provided by the manufacturer (the required level of current and voltage is indicated on charger, which was sold complete with the gadget).

Frequent short-term recharging, contrary to popular belief, does not harm the battery. The current with which it is charged has a much greater influence. It is preferable to charge lithium batteries with low currents, although this takes longer.

If the battery capacity of your device has decreased due to wear and tear, the only solution is to replace the battery with a new one.

Using the gadget in cold or hot weather

When using a mobile device in unfavorable temperature conditions (up to +5 ⁰C and above +30 ⁰C), the battery discharges noticeably faster, but at temperatures close to room temperature, its capacity is immediately restored to its original level.

If you don't do this too often, the battery won't wear out quickly, but for calls in the cold it's still better to use a headset and keep the phone in a warm pocket.

High screen brightness level

The screen of an Android mobile device is the main consumer of energy. The brighter it is illuminated, the faster the battery drains.

The use of adaptive backlight, which changes depending on the ambient light (available only on devices equipped with a light sensor), helps reduce battery consumption. To enable it, select the “Auto” checkbox in the screen brightness settings. To prevent the screen from remaining on when you are not using the gadget, set it to go into sleep mode after 30-60 seconds of inactivity.

Resource-intensive features

After the screen, the next active consumers of energy are:

geolocation;
live (animated) wallpaper;
NFC and Bluetooth;
mobile Internet (3G, 4G).
Wi-Fi.

If they are all involved at the same time, even the most capacious battery It will run out very quickly, so whenever possible, turn off what you are not using.

Unstable cellular connection

You may have noticed that when you spend a long time in places where the phone has poor reception of the operator's base station signal, for example, outside the city, the battery discharges faster than usual. This happens because more energy is spent maintaining an unstable, intermittent connection.

The battery will drain faster even if the problem occurs with only one of the two SIM cards. To save charge, it is better to disable such a SIM card for a while.

Apps and widgets running in the background

Many Android applications and widgets, after installation, register themselves in autorun and work in the background all the time while the device is turned on. When there are a lot of such applications, the device not only discharges very quickly, but also noticeably slows down, so startup should be kept under control and allowed only to those programs that need it (antivirus, optimization tool, utility utilities, instant messengers, etc.).

Unfortunately, the autorun control functions of custom and system applications not in Android. But it becomes available after receiving root rights(superuser) and installing special utilities on the device, such as:

Startup Manager and some others

There are utilities that allow you to manage startup without root rights, but they do not work on every gadget and do not always work correctly.

Applications that the user himself launched, but after they were no longer needed, he forgot to close, can also consume battery resources. The accumulation of such programs not only loads, but also heats up the processor, which in turn heats up the battery. And when heated, as we know, the phone battery drains very quickly.

Control over processes that actively consume energy is also best entrusted to special utilities. For example, the following:

- DU Battery Saver etc.

By the way, most of them include cleaning the system from unnecessary files, processor cooling, charging optimization and a number of other tasks. To keep your device in order, it is advisable to use one of these utilities constantly.

Frequent reboots and turning the device on and off

Wanting to save charge, some users regularly turn off their mobile gadget. Sometimes even several times during the day. This is another reason why the battery drains too quickly, since when the device starts up and the operating system loads, the energy consumption is close to the maximum.

While you are not using your Android smartphone or tablet, you should not turn it off completely - just turn off the screen, complete resource-intensive tasks, disable communication functions (Wi-Fi, GPRS, 3G-4G Internet, GPS, NFC and Bluetooth), background data transfer, sensors and vibration motor. To do this, most mobile gadgets have an energy saving mode, the activation button for which can be located in different sections of the settings (parameters) menu.

Mobile virus infection

Malware that attacks Android devices does not always operate openly. They often carry out activities that are invisible to the user, and the only signs of their presence are empty accounts and very fast discharge batteries, including in standby mode.

Exclude hidden viral infection should be followed in case of any non-standard behavior of the gadget, for example:

The phone or tablet wakes up from standby mode without any active action on your part.
The device is in sleep mode and becomes warm.
On the device without your participation they turn on Wi-Fi modules, geolocation, mobile Internet and others. Or they cannot be turned off.
Appeared in the list of outgoing calls and SMS unknown numbers, and in your browser history - views of sites that you have not visited.
An application has assigned itself as a device administrator without your knowledge.
By unknown reasons stopped starting Google Play antivirus and other security applications.
Any system functions have stopped working.
Volume increased for no reason network traffic devices.

How to find and remove mobile virus, read on our website. The instructions are relevant for Android phones and tablets of the most different brands: Samsung, LG, Xiaomi, Philips, Lenovo and others.

System or hardware failure

Some users of PCs and laptops have encountered such a problem as incomplete shutdown of the computer, when the screen goes blank when the operating system is shut down, but some devices remain active - the cooler continues to rotate, indicators light up, etc. The exact same problem occurs on mobile devices, it’s just not so easy to notice, because smartphones and tablets do not have a cooler, and the indicator only shows the charging stage. In the event of such malfunctions, the device essentially remains on constantly and, accordingly, even in a “sort of turned off” state actively consumes battery energy.

The causes of such problems may be faulty applications, viruses, operating system errors and malfunctions in the device’s hardware (including connected devices - memory cards, SIM cards, etc.).

The only symptom that allows us to suspect incomplete shutdown of the device is too high consumption battery charge at a time when it should be minimal. And to make sure whether this is really your case, just remove the cover of the phone (tablet) and check the processor temperature with your fingers. If the device continues to work after being turned off, its processor will remain warm. Sometimes in this condition the body of the device heats up slightly, but sometimes not - it depends on its design.

In such cases, what can the user do without contacting the specialists:

Remove applications installed before the problem appeared (if you were able to record the time it started).
Conduct an anti-virus scan.
Disconnect all connected devices.
Reset the system to factory settings.
Remove the battery (if it is removable), hold down the power button for 20-30 seconds and replace the battery.
Reflash the device with known working firmware.

After each manipulation, check the gadget by turning it off. If the problem is not solved, you will have to take it to a service center for repairs, since the problem itself will not go away, and the battery will exhaust its life much faster than during normal operation.
