General fix for battery drain issues

The WiFi battery drain might be somehow real but on any Android device there is actually a legitimate battery drain problem. Usually the battery drain happens after an Android update. The easiest and quickest fix is to update all the installed apps so they can be compatible with the new version of Android. Then wipe data, cache and Dalvik cache and reboot the device normally.

There are two ways to clear app caches; you can choose to clear each app cache individually or clear them all. To clear app caches individually go to Settings > Apps > Select app > Storage > Clear cache. But it’s much more easier to clear all the apps caches in the same time. To do that go to Settings > Storage and USB >Cached data > OK. 

You must clear system cache as well not only apps cache. To do that turn off your phone and boot into recovery using the proper key combination. It depends on the device model but in most of the cases you will need to press Volume Down and Power Button in the same time.

Navigate using the Volume buttons and select Wipe Cache Partition and then press Power button to confirm. Then reboot your phone and you are done. The battery drain problem should be solved. If you want your battery to last longer you should consider also these tips for improving battery lifetime on Android. So besides finding what is draining your battery faster than ever, you should also try to improve the overall performance of it.

If the battery drain still persists after taking these steps, the last thing you should do is to factory reset it. First save all your personal files somewhere else and make sure they are safe because you are going to delete everything on your phone and make it like new.

You can do the factory reset using the recovery or simply by going to Settings > Backup and reset. From there find the factory reset option and do it. If this doesn’t work then consider reflashing the Marshmallow firmware.
