The phone doesn't run out of charge. Applications and background activity. Battery controller problems

What could be the reason that the Android battery drains quickly? And most importantly, how can this be fixed? This article will discuss the main causes of this problem and ways to solve it.

Small battery capacity

The most banal reason for this is its small capacity, that is, less than 1600 mAh. Unfortunately, in this case, you can only put up with what you have and try to use the minimum energy on which the smartphone runs wisely. This means following tips such as not running unnecessary applications and disabling unnecessary functions. The actions that need to be taken in such a situation will be described in more detail in the article below.

Battery wear

Sooner or later, all batteries come to this point. And the battery on Android sometimes discharges quickly due to the fact that during the use of the device it has worn out and needs to be replaced. You can match the original battery to the model, but this is difficult and expensive, you can buy a fake or use products from battery manufacturing companies like CRAFTMAN, which supply universal batteries for smartphones, tablets and other gadgets. In any case, choosing a new battery is not so difficult: there is enough choice on the market for technical products.

Running programs as a factor in why the phone battery drains quickly

Android is an operating system, which means that after downloading and closing any program, you cannot be sure that it will not remain running. Many running programs are another reason why the battery on Android quickly drains. What to do? First, use the built-in or advanced cleaning options. Secondly, reboot the device from time to time, as is done on computers and laptops to reset the operating memory. This not only saves battery, but also simply helps your smartphone or tablet work faster.

Unstable communication signal

Recently, many mobile operators have been offering 3G coverage to users, but almost always it is, to put it mildly, unstable. This means that when moving around the city, the network on a smartphone or tablet with a SIM card is forced to constantly switch from regular 2G to 3G. Because of this, the battery on Android also drains quickly. To prevent this from happening, you can force only GSM in the settings.

GPS

Many Android devices have GPS enabled by default. But in reality, only a small number of people use it. That’s why you can safely disable this function if it’s not needed, since it only once again “loads” the phone and takes energy from the battery. Even if this function is in active use, you can enable it only when there is a real need for it.

Screen brightness

The screen brightness can be adjusted. And there is a clear proportional dependence of the energy supplied by the battery on its value. A very bright screen is rarely something you can't do without. Among its disadvantages, in addition to the above, is also excessive strain on the eyes. All you have to do is choose the ideal value for yourself. In addition, information on a dim monitor is much more visible in strong sunlight.

Tips for extending your device's battery life

In addition to eliminating the reasons described above, you can also use the following tips to extend the battery life of your Android device. Their effectiveness on different gadgets may vary, but it has been tested by time and other users.

Battery calibration

Battery calibration is the process of bringing the battery into an optimal state for use. This is done because the device may incorrectly remember the charge level and its consumption, as a result of which, even if in fact the level is 95 percent, the device perceives this incorrectly and the smartphone/tablet turns off. If you simply replace the battery, the problem will remain, which means that your efforts will be wasted.

To calibrate the battery on GooglePlay, you can download the corresponding application, but you can also do it manually. First of all, you will need to completely discharge the device, remove and insert the battery back without turning on the device, charge it to one hundred percent, carry out the actions with the battery from the previous point, and turn it on.

In fact, there are many calibration options; you just need to choose the one that suits you.

Disabling automatic system updates

It is known that disabling automatic system updates not only extends the battery life of the device, but also prevents unnecessary downloads, and therefore reduces Internet traffic costs. It is recommended to set “Ask before installing updates” in the settings. They are available on GooglePlay in the "My Applications" section.

"NO!" unused processes

It is recommended to regularly clear memory of unused application processes, clear temporary data, Internet browser cache, etc. To do this, you can use both standard system tools and additional ones.

You should not download applications that supposedly save battery capacity; in fact, they only load the system even more.

If the battery on Android runs out quickly (Samsung, for example, often suffers from this), you need to turn off all unused networks, uncheck “auto-rotate screen” and “auto-brightness”.

Special advice for smartphones with an AMOLED screen: it is recommended to install dark themes rather than bright and light ones.

Additional actions

If you approach the matter of discharging your Android smartphone/tablet with all responsibility and foresight, you can also do the following:

• Buy a high-power battery that will definitely guarantee a long charge life. Such batteries are usually thicker than regular original ones, and they come with an additional back cover, which makes the gadget heavier and larger in size.
• There is also an option to purchase a battery case. The disadvantages of this and the previous points are that they are not possible for all devices.
• You can purchase a portable charger, as it is also called an external battery. It allows you to connect your phone to it and charge it again. It itself is usually charged from an outlet. high-capacity, so there is no risk of sudden shutdown of the device.
• Buying just an extra battery is another effective alternative. When one runs out, you can simply replace it with a spare one, especially if the Android battery is quickly draining.

Instructions

First you need to go to the “Wireless Networks” settings section. Initially, see if systems such as Wi-Fi, Bluetooth and GPRS are enabled. These networks together consume a large amount of battery power. And if you are not going to transmit or receive any data via Bluetooth, then turn it off. If there is no Wi-Fi access point in the near future, then turn off this system too. And if you are in a place where 3G does not reach you, then turn off mobile networks in the settings.

Geodata or GPS also consume a huge amount of charging, so it is advisable to turn them on only when necessary. You can disable GPS in the settings window in the “Location Services” tab.

Now we need to figure out the amount of energy consumed by the display. After all, the longevity of the battery also depends on it. In the display settings, you need to change the screen brightness to 30-40%. If the weather is not sunny and your vision is good, you can reduce the brightness to an even lower value. In the display settings, you also need to reduce the screen time. The optimal value is no more than 30 seconds. And then the phone should go into sleep mode.

Installed applications consume a lot of energy. And not everyone knows that when you try to close some offers, they simply disappear into the background and continue to consume power. Close applications completely in the “applications” or “application manager” section of the settings. There you need to open running programs and in each running application click on the “stop” icon. This process is quite lengthy, and programs can be disabled in another, faster way.

You can download the absolutely free Battery Doctor program from Google Play. After installing it, you can close all applications running in the background with one click of the “Optimize” icon. The program also allows you to adjust the screen brightness, disable and enable wireless networks, ringer volume and phone vibration. An additional advantage will be that thanks to the Battery Doctor application you can find out the charge level in percentage, as well as the approximate amount of battery life.

If the phone is Android, then we’ll look at how to deal with this and what can be done. It's no secret that Android uses up the battery to the maximum and that it barely lasts for a day. This is the situation with any Android smartphone, be it Samsung or anything else. The iPhone also discharges quickly, but we’ll talk about that in another article.

Android

There is a certain set of actions, by performing which you can achieve more or less economical consumption of battery power. You shouldn’t expect that the battery life from charge to charge will increase significantly; you still need to remember that Android itself requires good battery power. And if the main complaints are that the phone quickly dies down during the game, then nothing can be done here - for such games it is better to purchase phones that are equipped with a more capacious battery. It is quite possible that you can choose another separate high-capacity battery for your phone. Well, and of course, the more applications are installed on your phone, the faster it will sit down. Of course, today there are plenty of freely available applications, and they all seem to be needed. But if you do not use the application very often, then you can wait to install it. For example, applications for accessing Internet banking are, of course, a necessary thing. But you can purchase Russian Railways tickets directly from the Russian Railways website. How to register to purchase Russian Railways tickets online is described in detail at http://webereg.ru/servisy/rzhd-pokupki-biletov. That is, as a rule, you can do all important actions simply by knowing the site address. By the way, it’s good that not all companies release their own applications, because then you would have to choose, and this is a very difficult choice.
First, let's figure out in what cases it makes no sense to do anything with the battery:

1. Its resource has been exhausted.
2. There was physical impact on the battery.
3. The battery is swollen.

When charging, a different charger with the wrong voltage and current was used.

What takes the longest battery life in a smartphone?

The screen comes first, the communication modules come second, that is, the Internet, wifi, and so on. That is, even when the screen is turned off, your battery is guaranteed to run out if you do not turn off the communication module. However, Android has the ability to optimize battery consumption even in this case.

Screen

Whatever the device is, if it has a screen, then it is the main consumer of energy. Therefore, if your screen is very bright, the battery will drain quickly. It is better to set it in the settings so that the screen brightness is adjusted automatically, which will allow you to keep it at a less bright level in the room. However, not everything is simple here either - in this situation, the light sensor will also draw energy onto itself.
Plus, you can also save energy if you reduce the time before the screen turns off.

4G LTE connection. Only in some regions of the country it is possible to keep this connection constantly on. In many other regions, this connection is unstable, and therefore automatic switches to 3G occur constantly, and this already means an uneconomical load on the battery. Just set 3G as your default connection. To do this, go to Settings - Mobile networks - More and change the network type.
Mobile Internet. In fact, it is better to turn off mobile Internet on your phone, because it is not always required. If your smartphone does not have a super-capacious battery, it will last longer if you monitor your Internet connection and connect to operator towers only when necessary.
Bluetooth. It is generally better to disable this module. If you use it sometimes, then it is better to turn it on at that moment.
Wi-Fi. As is already clear, it is better to enable this type of communication if necessary. Since the battery drains quickly and there is no particular need to always be online, it is better to connect to the wireless router only when required. In addition, turn off notifications about searching for and availability of wireless networks. To do this, go to “Additional functions” and turn off the “Network notifications” slider. Report the presence of public networks." And also turn off the “Always search for networks” slider.
GPS. This is essentially a sensor that comes with your smartphone. It does consume a lot of your battery power.

Disable sensors

The sensors include the GPS already described above, automatic screen rotation, NFC (communication module). It is better to disable automatic screen rotation, because it is a gyroscope that uses a lot of battery life. Android 5 Lolipop has the Google Fit app, where such sensors still work, but in the background. Therefore, here you need to disable the application itself.

NFC. Not all phones support NFC, but more and more devices do. Although it cannot be said that users often resort to it. Therefore you need to disable it. To do this, go to the settings section “Wireless networks” - “More”.

Turn off vibration feedback

Android has a built-in vibration feedback feature that is turned on by default. This refers to vibration when touching the screen. However, all mechanical movements (in this case, an electric motor) are quite energy-consuming. To disable this feature, go to Settings, then Sounds and notifications, Other sounds.

Applications

It’s probably clear that the more applications running on a smartphone, the faster the battery drains. You can see how much the battery drains from certain applications if you go to the Settings section, then Battery.
Games and the phone's camera are supposed to use more energy than other applications. And if a regular e-reader turns out to be a record holder for battery consumption, then most likely the e-reader software has its own problems. You might be better off finding another reading app with more adequate software. Then about various effects and cool transitions and animation - all this is design and it is very energy-intensive. Use it if you want, but the battery will run out very quickly.
There are programs that constantly want to update, even when network access is disabled. They work in the background and also consume a lot of energy. Here, decide for yourself whether you need them or not.
You can take another step like this. Go to the settings section, then to Data Transfer. There will be a list of applications that constantly use data transfer. Do you need all of them? Most likely, you will have to disable some of them or completely remove them. In principle, on some phones you can set a limit on the app's traffic usage. To remove unused applications, just go to Settings, then Applications. There you can disable the Press, Google Fit, Presentations, Docs, Google+, etc. applications. Attention! Do not disable the necessary Google services at the same time.
Have you probably noticed that some programs constantly give their notifications? They can also be disabled. Settings – Applications, then simply uncheck “Show notifications” (option for Android 4). For Android 5 you need to go to Settings - Sounds and notifications - Application notifications. Here you turn off notifications.
If you still need software updates, then on some phones it is possible to set the interval between updates. You can also disable the automatic synchronization feature.
If you decide that all these steps are difficult to do and just use some task killer or Android cleaner, then this will only bring satisfaction for the first 5 minutes. Next, the phone will try to launch all the programs and applications that were just closed, and this will drain the battery even faster. The freed memory is free only for the first five minutes. It is better to manually go through all the steps described, and then close all unnecessary applications from time to time. This is the only way to increase the battery life of the device and keep its memory empty.

Phone power saving features and battery life apps on Android

Almost all new generation phones have an energy saving function. Be sure to use this feature. At the same time, the processor clock speed is reduced, animation is removed, and unused processes are disabled. Sometimes turning on the power saving mode gives up to 2 hours of additional battery life.
There are various freely available apps that are designed to optimize energy saving and limit battery usage on Android. But these applications act like task killers, that is, they simply close unused programs, and then the system starts opening them anyway, which in any case leads to excessive consumption of battery resources.

Key Points You Need to Know

Use only the original charger to charge the battery. Even charging your phone via micro-USB using a tablet charger or via a computer's USB port is not recommended. Well, about the computer, then if you use a normal power supply and with an honest 5 V and< 1 А, то подойдет. Если ваш смартфон рассчитан на зарядку 5В и 1,2 А, то при зарядке зарядным устройством, которое дает на выходе 5 В и 2 А количество циклов зарядки сократится. А если напряжение на выходе зарядного устройства будет 6 В, то количество циклов зарядки еще сильнее сократится.
You should not leave your phone in the sun or in the cold. In this case, the battery life is greatly reduced.

Progress does not stand still; the speed of operation and, accordingly, the energy consumption of smartphones is growing every year. Manufacturers are constantly improving the characteristics of phone batteries. If 5 years ago batteries with a capacity of 1500 mAh were considered the norm, today 3000 mAh is not enough.

Developers of the Android system and applications for it are also trying to optimize their products to reduce energy consumption as much as possible. However, we still experience increased battery drain. There is a situation where the phone is not very old, the battery is not worn out (), but the phone begins to discharge quickly?! It would seem that the screen brightness is set to 50%, all wireless modules are turned off (3G/4G data, Wi-Fi, Bluetooth, GPS), but the phone still dies quickly?! In this article, we will try to understand the reasons for this sudden behavior of an Android phone.

Finding reasons for low battery

Recent Updates

Often, recently updated applications can be the reason why your phone battery suddenly drains. To see a list of apps that have recently been updated, go to the Google Play Store, select the "My apps and games" option from the menu, then go to the "Installed" tab and sort the list of apps by date they were last updated.

Pay special attention to the first applications in the list; the reason for the rapid drainage of the battery may be in one of them.

Battery usage by apps

In the Android system settings there is a "Battery and Performance" section, where you can view statistics on battery use by applications and phone components (screen, Wi-Fi, etc.).

Examine its contents for programs that consume the most battery power.

CPU load

It is also useful to find out what happens to the phone's processor in standby mode. A wonderful little program called CPU Spy will help you with this.

It displays statistics on the phone's processor usage at different frequencies. The "Deep Sleep" field indicates how long the phone has been sleeping.

The higher the percentage, the longer the phone was in sleep mode. If other fields (frequencies) predominate, something prevents the device from “falling asleep”. These can be both system and third-party processes of installed applications.

Solving battery problems

If you find suspicious applications, we recommend deleting those that are at the beginning of the list and that you practically do not use, especially if they have recently been updated. In general, we recommend deleting applications that you do not use, even if they are not on the list. From experience, we note that this helped one phone with similar symptoms.

If for some reason you do not want to delete applications, clear their data (re-configuration will be required, and for client applications, re-authorization). To do this, go to Android settings, select "Applications", go to the "All" tab, find the desired application in the list and open its properties, click the "Close" button (1), and then "Erase data" (2).

If you have deleted suspicious applications, and also cleared the data of the necessary ones and still observe increased energy consumption, then in this situation we recommend making a backup copy of important data (contacts, SMS, photos, videos, etc.) and performing a complete reset of the device (Settings > Advanced > Backup & Reset > Factory Reset), then get your important data back on your phone.

If this does not help, then most likely the problem is in the firmware or even in the hardware of the phone. In this case, we recommend taking the device to a service center for diagnostics and repair.

Many users are familiar with the problem that the Android battery drains quickly. Reasons vary from battery problems to phone memory usage.

Most often, the problem is encountered when there are a large number of applications on the device. Some applications require a lot of energy and memory. Their list can be viewed in the battery settings.

Rapid battery consumption can also be caused by the presence of malware on the smartphone, incorrect downloading of Android OS updates, or lack of free space. To fix the problem and prevent it, you need to know the exact cause.

Before diagnosing the cause, answer a number of questions:

1. How long have you been using the device?
2. How much free memory is left on it?
3. Does the use of network communication affect discharge?
4. Is your phone running slower than usual?
5. Does the phone get hot during operation?

It is considered normal if the battery runs out quickly when using applications or games. Also, the sites you visit, such as advertising banners, can provide additional load. Some sites are also demanding to visit.

Battery wear

If you have been using the device for more than a year, the battery may be worn out. To avoid premature wear, it is necessary to maintain its condition. Careless use and ignoring recommendations can lead to battery damage. This is especially true for tablet owners - their work requires a lot of energy. Tablet batteries are also more susceptible to premature wear. For prevention, you must follow the rules of correct charging:

• Avoid operating when the charge level is below 10%;
• do not leave the device in direct sunlight;
• reduce use time when charging;
• Do not unplug your phone until the charge level reaches 80%.

It is also undesirable to work with the device when charging, since over time this leads to damage to the charger and the connector itself. Problems with the connector can also cause battery wear.

After updating Android, the battery drains quickly

What to do if the battery runs out quickly on Android, but the device is relatively new?

To update, use only the official Google app, avoid third-party software. If the phone has been reflashed, the problem may be due to flaws in the program. Only reinstalling the operating system will help here.

The problem is often encountered among Samsung owners; on the forums there is a problem of rapid discharge after an update. There is a version that with the advent of new models of Galaxy smartphones, older ones are getting updates that specifically overload the battery. With the help of such manipulations, manufacturers push people to buy new Samsung devices. The version sounded implausible before the scandal with Apple, which was accused of similar manipulations.

How to fix it?

After installation, go to settings, find information about the device. Disable "developer options" if they were active. Also in the settings there is an option to roll back the latest update. Rapid battery consumption can be caused by flaws in the new OS, using many background processes.

Using a 4G mobile network causes your smartphone to discharge faster. While moving, the device switches from one communication tower to another, which puts a strain on the battery. The device requires a break from all types of communication - Wi-Fi, Bluetooth, mobile network. At night or when there is no need, you should put the device in “standby mode”, and when traveling, leave only 3G.

Screen

Also, the battery is consumed by the use of auto-rotate screen, animated screensavers, and screen brightness. To save battery, use static images as screensavers, adjust brightness and auto-rotate manually depending on your needs. To reduce energy consumption, enable automatic brightness adjustment - at night the phone will reduce the brightness, and in sunlight it will increase.

Charging runs out quickly when background programs are highly active. You can disable their operation manually in the menu settings. Why do they work even after being turned off? Some applications require processes to run at any time, even when the device is not in use. The problem is solved by installing utilities that close them forcibly.

Android also has system applications that you probably don’t use - press, presentations. You can delete them through settings - applications.

Removing unnecessary programs

The main problem when there are a large number of programs is the load on RAM. Files that load memory include browser history, cookies, download paths. Clearing your phone's cache helps free up additional memory, which improves its performance.

What should you do if your phone battery drains quickly and requires an Android update? If a large number of media files have accumulated on your device, this becomes an obstacle to the operation of applications. The device begins to quickly discharge and heat up. Sooner or later it becomes impossible to take a photo or download a media file. There are also problems updating applications.

To monitor the cache on your phone, periodically clear the cache in your browser; this function is available in the settings of the applications themselves. Download the CCleaner utility for Android, which will help you free up memory on your device. The utility also corrects system errors, which will also help increase performance.

Photos and videos take up a lot of space on the device. Personal media files can be transferred to Google Drive. Or simply transfer the files to your computer or external storage device.

Malware – viruses

Viruses can get onto your phone by downloading files from dubious resources. The first sign of their presence is the phone overheating even at rest and slow operation of applications. Viruses launch background applications that cannot be closed even with the help of special utilities. Some types of malware delete personal files by infecting other devices through a direct connection.

There are two ways to rid your device of viruses:

1. Connect the device to the computer and scan it through a third-party antivirus.
2. Download antivirus to your device.

Any paid antivirus has free trial access, be it Kaspersky or Dr. Web". To use full functionality, it makes sense to purchase the paid version.

Some Android smartphone models have built-in energy saving features. To check its presence, you need to go to settings - battery.

To extend the battery life, it is necessary to expose it to low-charge conditions as little as possible. If your smartphone discharges critically quickly, none of the methods described above will help. Using the device with a faulty battery may worsen its condition; contact a service center.

In pursuit of low prices, you may encounter unqualified repairs, the consequences of which may be more expensive. The battery may be replaced with a low-quality one that will not cope with the load. When choosing a service center, you need to make sure that the replacement will use components from an official manufacturer.
