It also includes major bug fixes and everything else needed. Please check first if your variant or network carrier released a stable version before updating the device.

2.      Factory Reset

3.      Reinstalling Apps
After the factory reset, closely monitor each application you are reinstalling. For every reinstallation, check the battery monitor if something changed to know what app really caused the battery drain. Google apps and services can also be culprits on the battery.

4.      Uninstalling Updates
There are system apps which you aren't allowed to uninstall without administrative rights provided by root access. If the culprit app is something like this, uninstall all updates to bring it back on factory version.

5.      Disabling Bad Apps

6.      Syncing Configuration
Email, social apps and other similar things are invisibly syncing without your knowledge. Launch these apps and go to their settings then manually set syncing time or set to 'never' to prevent constant refresh of data. In addition, disable the auto-syncing mode to save power.

7.      Screen Display

8.      Wireless Connectivity

9.      Prefer 3G over 4G/LTE

10.  Home Screen Management
Widgets are beautiful especially with animations but 3D widgets and animations are killing your battery. Moreover, most widgets with details are syncing over data that severe battery as well. Minimise the number of home screen panes and only use widgets truly worth displaying.

11.  Task Manager

12.  Power Saving Tool
For dire and emergency situations, use the Power Saving tool located at the notifications shade to let the device handle battery preservation.

13.  Airplane Mode

14.  Android System
A file called "gsiff_daemon" could cause severe battery drain displayed as Android System. It is a non-utilised but highly active GPS sensor daemon that is always on for nothing. Download the ES File Explorer from Play Store > Go to Developer options > Show CPU usage > Look for "gsiff_daemon to pop-up > Launch ES File Explorer > Menu > Settings > Root Settings > Root explorer > Up to root > Mount file system > Go to System > bin folder > rename "gsiff_daemon" to "gsiff_daemon.bak" > Reboot the device.

15.  Google Play Services
Some reports of battery drains are caused by Google Play Services and unfortunately, Android devices use the Play Store most of the time. Even if you uninstall the updates, the Play Store will automatic drag it again to your system. The only way to avoid this is to use your device as a phone, music and movie player or picture taking.
