So I had my phone update to android 12 about 4 days ago. And the battery drain since then has been insane. Normally I was able to last for a very long time with my battery. Yesterday I was looking at stuff on the internet with mobile data on for about half an hour I think and it drained 20% or so. This morning I charged it to 100% and went to take a nap for a few hours. 3 hours later, with Always On Display turned off, it had went down to 90%. Without having touched it at all. Wiping cache partition doesn't seem to have helped. I use CCleaner after booting my phone to shut down a couple of apps that automatically launch on start and about once in a day to shut down the other stuff I have done during the day. CCleaner can't possibly be the issue, it never gave me problems before. I hope this gets fixed soon 😞
