Battery life is always very low in our smartphone-centric world, and you often find reasons yourself confused why your battery one day drain very fast and then lasts for a second day. android has been trying to fix that for many and many versions, and the latest Android 8.1 Developer Preview adds one more weapon to your arsenal in the fight against battery drainage. It will not assist you to win the war, however, it’ll more simply answer the question of which app has been misbehaving and how.
On Android 8.1, if you check the Battery settings, you’ll see one highlighted app highlighted at the top with a red warning battery icon. it will tell you which app has been draining the battery and the way. in the few examples we have seen, Maps Preview and Tile were said to be requesting location often, whereas Fenix was keeping the device awake.

Tapping on the message provides you a method to remedy the problem. as an example, in the case of Maps Preview you’ll turn off location for the app… that defeats the purpose, but oh well.
Why your battery will be drained quickly maybe one-day android can explain to you exactly, including non-app reasons like you used Bluetooth for too long or your reception was crappy for most of the day, but for the time being, this can be a small step in the right direction.
