I'm getting insane battery drain since the latest update. Sick of it tbh. It happens everytime I update and everytime I have to factory reset to fix a wiping cache partition doesn't work. Last time I buy a Samsung phone.
I have the same problem since I updated. My battery lasts barely a day now. The culprit according to my screenshot is the One UI launcher app. I have booted in safe mode for a day because support told me to. Battery worked well but all I can do then is call people. Hardly a smartphone then...
So I then started normally again and it worked well for half a day. Now the launcher is sucking out the power again.
They also told me factory reset but that's definitely the last thing I'll try because I don't have the effing time to spend half a day trying to fix a phone which was working perfectly fine before.
I have to say: I hate, hate, hate the way companies like Samsung do support. They let a only half-informed community do the job. You get random people who don't really help you. And then basically nothing happens.
So, no, I don't know how to fix it. The support told me that standard ***** about malware or "software conflict" which frankly means, that they have no clue either.
