My phone battery is draining hardcore!

[ChooseAnotherName]

As you can see, I've used 40% in the past 3 hours. Losing 12% per hour. I played pubg mobile for 20 minutes. I don't understand how I can fix this.

Welcome to Android Central! Which phone? Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).


You might have to install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.
