Enter safe mode and observe your devices battery backup and whether its getting overheated aren't
Guide to enter safe mode.
1Power off the device.
2Now turn on your device by pressing the Power key . When Samsung logo appears, press and hold the Volume down key .
If your device functions correctly in Safe Mode, it is most likely that the issue lies with a 3rd party application that can be uninstalled to resolve the problem.
