Every year, developers improve the technique, introduce new features. The hardware of a modern smartphone is almost the same as a computer: several cores, a large amount of RAM, support for 3D graphics and video in HD. But the higher the functionality, the shorter the battery life. This is the only drawback that developers cannot fix.
Therefore, battery saving on Android devices is practically the most important question for users.
After the purchase
You need to start taking care of the battery immediately after purchase. Firstly, for the first time, you need to charge the smartphone in the off state. Secondly, at first use, discharge the battery to zero, and only then turn it on. In the future, you need to put on charge when about one third of the energy left in the battery. Thirdly, do not leave the phone connected to the network all night. Because after a full charge, he will again begin to lose charge to a certain level, and after that he will begin to recharge again. This will reduce the battery life.
If you follow these simple rules, the battery will last much longer and will not cause problems.
Data transfer
A huge amount of energy is spent on data transfer. One has only to turn off Wi-Fi, mobile Internet (3G, GPRS / EDGE), Bluetooth - and the battery saving on the "Android" device will be a significant percentage.
The data transfer in the settings is turned off, or you can simply set the “On Airplane” mode. But the latter option may have consequences - it disconnects the connection completely. You can skip an important call or message.
The same goes for GPS. If there is no need to determine your position, then it is more advisable to turn it off.
Display
Screen brightness is best reduced to an acceptable level for the eyes. The backlight also “eats” a certain amount of energy. And the brighter it is, the more charge will be required. You can do this by going to "Settings - Display - Brightness". Some models have a function for automatically adjusting the brightness. It adjusts the backlight depending on the ambient light environment - this also saves battery power on the "Android" devices.
It is recommended to put a picture in dark colors on the screen saver. Because no matter how you adjust the brightness, a bright picture will consume more energy. And it is worth abandoning live wallpaper: it is beautiful and stylish, but very uneconomical.
To save energy, it is also necessary to lock the screen when the phone is not in use.
Vibration
Vibration spends a decent amount of energy. Moreover, on “Android” it is used not only for calls and messages, but also in applications or when you tap the screen.
In order to avoid missed calls, the vibration call can not be turned off, but in all other cases, turning off the vibration is saving battery power on Android smartphones and tablets.
System settings
Disable auto-updates. Their work is inconspicuous, but while using the Internet they are very stressful system.
Try to reboot the system less. Oddly enough, but the battery saving on the "Android" devices will be greater if the device is not rebooted. The fact is that a lot of charge is spent on rebooting, because the phone has to turn off and turn on all applications, the system and other functions.
Background processes
Uncontrolled background processes are an energetic black hole. Therefore, it is worth closing applications that are not actively used. Even if the program is not running, its processes run in the background and consume battery power.
Also, the more applications launched simultaneously, the greater the energy consumption.
You can deal with background applications manually or with the help of the so-called "Task killers" (in another way - "Task Manager").
These are small utilities that “kill” processes. But programs do this not quite correctly, because of which excess remains in the phone's memory, errors appear and a frequent reboot is required.
You can also remove unnecessary processes from startup, again using programs. But if there is an application widget on the desktop, it will still start.
Widgets
Widgets create a lot of stress on the system. Even if you are not doing anything, Android is always ready for what you want to use the programs from the desktop. In addition, widgets are constantly updated, which also does not save battery.
Synchronization
In any smartphone on the Android platform there is a synchronization of accounts. It allows you to access data on any device if you know the username / password. So, if this function is enabled, then information is constantly exchanged with the remote server. This also requires a considerable amount of energy.
Disable it or not, this is a private matter for everyone. In certain cases, for example, in the event of a phone breakdown or loss, synchronization will come in handy for restoring contacts, messages and other data. Battery saving on Android devices should be reasonable, and you should not disable the really needed features.
Special programs
There are a lot of applications on the Play Store, free and paid, just enter in the search: “Application on Android, battery saving.” Such programs provide quick access to settings for data transfer, screen, applications, reduce the load on RAM, complete unnecessary processes. And as a result - saving battery.
The program on the “Android” device scans the memory for the presence of services that spend a lot of energy, and pauses their work. For the necessary programs, such as an alarm clock, there is a white list.
But before you decide on a specific program, you should carefully read the description, since most of these utilities are commonplace killers of processes that complete everything indiscriminately and can pose a threat to the correct operation of the system. At the same time, there is a great risk of running into an application that consumes much more energy than it saves. Also, before installation, you should consider on which version of the OS the program works. For example, the “Battery Saver” application on “Android 4.2” works fine, but on the version of “Android” 2.2 it will no longer be.
How to find energy consumers
You can independently find applications that consume too much energy, or that you don’t even suspect work. For this, the Android operating system has a special function. You need to go into the settings, select "About phone", then "Battery" and "Battery usage". After analyzing the applications that consume the most energy, you can disable them if necessary.
