So i made a similare post a few months ago in hopes of someone finding a fix or at least a cause behind it all. Well i did in fact find a fix for it and possibly whats causing it. The fix was just to factory reset the phone. Had AMAZING battery life after the reset, BUT only for a few days. Its been 7 days since i reset the phone and its back to "normal" with "Others" draining the battery once again.
The thing is, within the span of the issue coming back and the battery draining i also got myself a nice pair of Bluetooth headphones for work. So i believe Bluetooth is behind "Others" draining the battery. Before i got the headphones i could easily get 6h SOT with 14-17h idle. WITH Bluetooth enabled for 6-7h a day i can barely get 4h like before. Checking the battery graph however reveals that Bluetooth have only used MAX 5% throughout the day, while "Others" are back at 20-25%. Im going to check if not using Bluetooth for an entire day allows me to get those 6h SOT back.
Should also note that before i factory reset the phone, the only time i actually had issues with "others" draining the battery was while i was driving around with my car, WITH Bluetooth enabled for music. Seems kinda suspicious that the issue came back when i finally started using Bluetooth again.
In short: factory reset gave me great battery life. Got Bluetooth headphones so Bluetooth was active for 6-7h a day, Bluetooth however only used 5% battery while "others" are back at 20-25%.
