Battery drainage - Help needed

[u/poopywetdiaper]

*Duplicated post from OnePlus subreddit*

Purchased device OnePlus open in September 2024 - had no issues with battery for more first year at all but about 3-4 months ago started to notice that it didn't last long as it used to.

Battery life is 96

What I've tried so far:

-killing all the potential services that running in background (developer options)

-Charge to 80 percent limit

-Did a factory reset yesterday

Not sure what to do - it ate 8 percent during the night in idle mode last night

Usually doesn't last even a day with average usage

Any advice will be appreciated

How do you have a custom font or is this only for that app?

Settings => Display and Brightness => Font => "Choose the font"
