I've been experiencing a severe battery drain overnight that I haven't been able to solve.
Problem:
When left unplugged overnight, with no apps running, screen locked, my P7P running build number 2026030701 will completely drain itself. We're talking 80-90% to 0%, and it didn't always do this. When I first installed GOS about a month ago, it dropped maybe 30% overnight, which is perfectly fine. Checking the battery usage, the vast majority of battery drain was related to the system, either mobile data or WiFi, apps don't seem to be the problem here.
Attempted solutions:
Disabled background data for almost all apps, on the latest build, turned off adaptive connectivity (under the suspsicion it was connecting back and forth from WiFi and mobile data) checked battery health, which reads 100%.
I have no idea what to do here. I've taken a look at the system logs, if there's a root cause in there, I haven't found it.
