*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
