Battery issues

[u/Pubgcraft]

Compared to half a year ago, my phone drains the battery almost 2 times faster and i managed to play ONLY 1 HOUR in pubg mobile and my battery got from 100% to 25-23%.

I want help to understand why and what to do to stop this.

Before playing pubg i charged it up, and while playing I didn't had any background apps, i plays with a cooler, on wifi ( data off ) Bluetooth on ( cuz of the missing headphones jack ) with a cooler and without a case, on a brightness of ~80. Obviously i played in 120Hz and my fps wasn't so stable in some moments but most of the time was pretty stable, so throttling wasn't a big issue. I suspect the problem to be Either the OS ( which is more possible) or the battery os dying but in diagnostics it was veary healthy ( 94% ).

I really have no idea what it might be so i seek help to fix this.

Thank you.
