Reduce screen brightness. Remember: the higher the screen brightness, the faster the battery drains. If you set the brightness level to 100%, the information on the screen will be clearly visible, but the battery will drain very quickly. Therefore, lower the screen brightness and reduce the time it takes for the screen to turn off.
- Open the Settings app and select Display.
- Tap Brightness and move the slider to adjust the brightness level. This slider is also available in the notification panel (on some Android device models).
- Turn on automatic brightness to have the system automatically dim the brightness level in low light levels. This will reduce the screen brightness and reduce the battery drain rate.
Switch to battery saving mode. When various apps and services use the geolocation feature, it consumes some power. Maximum geolocation accuracy is necessary when, for example, you need to determine a route, but if you switch to battery saving mode, you will increase battery life.
- Open the Settings app and select Geolocation.
- Click Mode.
- Select GPS Only or Wireless to reduce the power consumption of Geolocation. In this case, the location will be determined using WLAN and mobile networks or using the device's GPS receiver.
Disable Google Now to prevent your device from always being ready to accept voice commands. When Google Now is turned on, your Android device is ready to accept the “OK Google” command. And this leads to faster battery discharge.
- Open the Google app on your device.
- Click the ☰ button in the top left corner.
- Tap Settings > Voice Search.
- Click “OK Google Recognition,” and then move the slider next to “Always On” to the “Off” position. In this case, you can use the Google Now service if you first open the Google application.
Activate power saving mode. This can be done in Android 5.0+ to limit certain services when the battery is close to being drained. This way you can use the last energy for more important purposes.
- Open the Settings app and select Battery.
- Move the slider next to the “Energy Saving” option to the “Enable” position.
- Click the "..." icon (next to the slider) to set the battery charge level at which this mode will be activated. For example, the power saving mode may turn on when the battery charge drops to 15% or 5%; This mode can also be enabled permanently.
Turn off vibration. Vibrating your device uses a significant amount of power, so if you are using a ringtone and don't need vibration, turn it off:
- Open the Settings app and select Ringtones & Notifications;
- Move the slider next to the “Melody with vibration” option to the “Off” position.
Recently, smartphones have become real everyday assistants in solving many problems, which has made this type of gadget extremely popular. It is especially worth noting Android devices, which are distinguished by the ability to install a huge number of applications and practically unlimited functionality. However, even such advanced technology is characterized by the emergence of various problems that require solutions.
Low battery
One of the rather specific features of the operation of gadgets on this operating system is that it significantly increases the requirements for battery capacity on the part of the device.
You can often observe that a certain Android standby mode eats up the battery. Since this phenomenon significantly reduces the battery life of the device, and also makes its use less convenient, such a problem cannot be ignored.
First, you need to figure out why the device needs this mode at all. First of all, it was designed for periods when the device is not in use by the user. Often, many owners of Android smartphones incorrectly determine which process consumes the most energy.
Standby mode
This mode, despite the popular misconception, does not waste battery power, but, on the contrary, helps preserve it. You should not rely on the statistical data displayed by the device in the Battery menu, since they only reflect the involvement of the process in working with this structural element.
If the decrease in charge significantly exceeds the norm, possible reasons should be examined:
- Live wallpaper or accelerometer sensor enabled;
- The device is overloaded with running background programs;
- Communication problems;
- Increased display brightness;
- Connection via mobile Internet or Wi-Fi;
- Airplane mode is on.
IMPORTANT! Do not forget that high energy consumption is typical for all devices running this operating system without exception. Only a few brands specialize in producing energy-intensive devices.
The solution to this problem will be extremely simple: turn off unnecessary components, reduce the brightness of the display, and also use the device by unloading unnecessary applications from its RAM. Only compliance with such rules can reduce battery consumption and make the battery life of the device a little longer.
Active use of phones leads to one problem - it begins to discharge quickly. A battery saving app for Android can come to the rescue. After all, the overwhelming number of mobile device manufacturers use this operating platform. All our readers will find it useful to review the most popular applications of this type.
Battery Saver (Download)
This free app has been downloaded by 5 million users and has an average rating of 4.3 stars.
According to the developers, the battery charge should last 2 to 4 times longer. Judging by the reviews, Battery Saver works. However, the maximum bar is clearly too high.
Battery Saver is very functional. The optimizer automatically disables programs that are not currently in use and shows how long the battery will last. There is a deep sleep mode. That is, when the phone is not used, wi-fi, synchronization, etc. are turned off. The application can independently determine which program consumes the most energy and disable it.
Among the minuses, it is worth noting a certain uncompromising nature and the lack of individual manual settings. All background programs will be closed, even if they are needed. In sleep mode, no application will be updated.

HD Battery (Download)
The program has surpassed the 10 million installation mark. This battery saving app for Android is very simple, intuitive and convenient.
Photo: HD Battery Using graphs, you can track not only charge consumption, but also device temperature and voltage. Not everyone needs these functions, but their presence is also welcome. The HD battery will tell you after what period of time the device will turn off if you listen to music, play games, use a navigator, etc. (for each specific case).
The upside is the customization. The application is free and available to everyone.
There are still some disadvantages. Problems with sound notifications and late data updates have been reported more than once. Taking all this into account, the application received a rating of 4.6.

As many as 400 million Android users have downloaded DU BATTERY SAVER. An average rating of 4.5 indicates that the application performs quite satisfactorily.
Photo: DU BATTERY SAVER The developers managed to create an intelligent battery doctor. It monitors and optimizes the phone’s performance in every possible way. Monitors applications that consume the most battery and notifies you that some background programs can be closed. The phone is also not allowed to overheat and the program lets you know if the wrong charger is being used.
All settings are set individually, the application can be downloaded for free.
Speaking about the pros, it is worth touching on the cons. Due to its super-functionality, malfunctions periodically occur. However, developers respond to complaints and release updated versions of their product.

DU Battery Saver (Download)
Another battery saving application for Android from the same developers as in the previous case. This time it’s paid – it costs $1. But its capabilities are an order of magnitude higher than those of its free brother.
Buyers get a smart and fully adjustable app. It is possible to configure battery saving modes, depending on the time of day or circumstances. Scanning and optimization allows you to improve the performance of the device and extend its operation for as long as possible. Memory is regularly cleared of unused programs. If you still need it, do not forget to add it to the ignore list. The quality of the charger's operation is monitored and the remaining time until charging is complete is shown. The application supports many languages, including Russian.
True, some users note that this program is still similar to its free version. Sometimes technical problems occur, which developers try to quickly fix. After all, the application is still paid.

This application has achieved more than 300 million downloads and a rating of 4.5 stars.
The free program allows you to monitor battery energy consumption and set individual modes. Convenient and clear design shows the amount of charge required for each application on the phone. The most energy-consuming ones are also notified. You can see the device's charging speed and its discharging speed. A detailed scan will identify any weak points in your work. About 30 languages are supported.
In any barrel of honey there is a fly in the ointment. “Battery care” was no exception. When the screen goes dark, all open programs are automatically closed. The battery, of course, is saved, but this is not suitable for everyone.
Avast battery saver (Download)
Avast also pleased us with a free battery saving application for Android.
The main principles of its operation are the optimization of all settings and the closing of background unused applications.
The developers have improved and significantly simplified the operation of the program. With just one click you can close all unnecessary applications that slow down your phone and consume a lot of battery power.
There are 5 main modes installed and it is possible to add your own. The application sends advisory notifications about mode changes. “Battery Saver” analyzes all processes quite accurately and can extend the life of the phone. You can monitor the discharge rate and the time until the device turns off completely.
Again, the app may not appeal to those who don't want to close background windows. However, as practice shows, this actually saves battery power.

Last on the list, but far from the last in the ranking, will be “Battery Saver”. The application has already been downloaded by more than 100 thousand Android users.
The program is very simple, convenient and quite effective. Conserving battery power is done by closing unused applications and generally optimizing the smartphone. Energy saving modes are set automatically. There is no possibility of adjusting them. But there is a noticeable plus - you can add to the white list those programs that cannot be closed.

The application was highly praised due to its simplicity, unpretentiousness and good performance. During sleep mode, it may not stop working wi-fi, bluetooth and data synchronization. Most reviews about it are positive. However, on some devices the program may not work correctly or correctly.
Dear readers! If you have any questions or comments on the topic of the article, please leave them below.
Optimizing battery consumption in Android. As I wrote before, I had problems with the Wildfire S battery draining quickly. Attempts with calibrating the battery did not lead to anything.
Changing the firmware from official to frankly custom also did not give any results.
For those who are faced with the same problem, I suggest you move on and find the source of the trouble. The next step is to try to find out which program may be causing unnecessary battery consumption. There are a lot of programs of this kind, but they recommend using SystemPanel, which I will use.
Here are short instructions for using this program:
1. Go to “Menu->Settings”, check the “Enable Monitoring” checkbox, and other checkboxes as desired (I have everything turned on except for displaying the temperature in Fahrenheit). Application activity monitoring is turned on, and a program icon appears in the system bar. Leave the device alone for a while, preferably overnight.
2. After some time, go to “Menu->Monitoring”. Click the “History” button at the bottom and see the graphs constructed. At the top we can set the interval for displaying information (if the monitoring worked all night, it is more convenient to set it to “8 hours”).
Description of charts:
- “battery charging” - shows the battery discharge.
- “device usage” - shows the device usage when the screen is on.
- “CPU activity” - shows the processor load for the entire monitoring time (including when the device is sleeping). A load of 0.5-1% by system processes in sleep mode is normal for most devices; anything more is unnecessary activity, the cause of which we will look for further.
3. We are looking for someone who did not sleep. While in “History”, click on the “graph” button in the upper left corner and select “Top applications” there. As a result, we received a list of applications and processes sorted by their activity when the CPU was loaded.
We click on the most active processes one by one and see information about the process; below we see the consumption history in the form of a graph. Click the “compare” button and more general graphs are added below. In this way, we can compare the graph of one process with the general graph of all processes and find out what participation this process took in the total mass (let me remind you that we are mainly interested in the time when the screen was turned off). This function is especially useful when there were rare but strong bursts of activity, i.e. when in the “Top Applications” the process may not be at the beginning of the list.
By looking through the graphs of all processes one by one, we eventually find the culprits. In addition, the item “System processes” is divided into many small processes, if among them there are very active ones, you can google its name, see what it is responsible for, find out about its activity from other users of the same device as yours, i.e. make an assessment of whether this is normal specifically for your device.
Example of work
Here is an example (based on the dream in the above screenshot). Looking at the graphs of each process separately, it became noticeable that Taskiller was showing unnecessary activity (in the bottom screenshot, the graph of the “Taskiller” process is at the very top).
Google annually adds many settings and functions to the Android operating system, many of which are hidden from the eyes of ordinary users. This was done on purpose, but with good intentions. The American corporation believes that if an inexperienced owner of an inexpensive Android smartphone accidentally activates certain important settings, then his device may begin to work slower or discharge much faster, so right out of the box all smartphones based on Google's OS have only Basic activated functionality, but it is very easy to fix.
Although every year all smartphones work longer on a single battery charge, largely due to better software optimization for hardware, a hidden setting in all Android smartphones significantly increases battery life, and can now be activated absolutely anyone, since it is definitely available in any custom firmware and in all models of mobile devices.
All smartphones based on the Android operating system have an incredibly large reserve of power, which is simply excessive for solving simple everyday screens. It's like driving a car, sometimes pressing the gas to the floor, and then slowing down again. In the case of smartphones, it’s not the gasoline that drains faster, but the battery charge. In order to increase the battery life of your mobile device, you need to launch “Settings”, and then go to the “Battery” section.
In the “Battery” section, three vertically located dots should be visible in the upper right corner, which you need to click on. In the menu that appears, you will need to select “Power Saving Mode” and then activate it. As a result, processor performance will be reduced, which will allow up to 50% increase in battery life on a single battery charge. This feature is available in all smartphones and tablets running Android 5.0 Lollipop and higher.
To achieve an even greater effect, the editors of the site recommend installing the “Doze-energy-saving” application, which significantly increases the battery life of all Android smartphones, since a lot of charging is “eaten up” by processes running in the background, which the user does not even see. After installing it, you need to select from the list only those programs and services that should continue to function normally.
It is worth choosing the most basic instant messengers, email clients and other basic programs that should receive notifications in real time, and not with a delay. This program works in such a way that all processes that are running in the background and consuming battery power are automatically frozen. This does not cause any harm to them or the data stored in them, and using this application can significantly increase battery life by up to 40% of the standard. This is especially noticeable at night, when without this program the smartphone’s battery will be discharged by 10-12%, and with it only by 5-6%.
