Severe Android System battery drain after March update.
Using a Note 9 512GB
I've been having this issue for about two months now, Android System is taking up just as much of if not more battery than my display most days. It started after the March software update, I've tried clearing the cache partition, limiting the CPU to 70% with battery saver, turned on optimize battery settings, disabled most apps to use battery or data in the background, I've uninstalled Samsung pay to check if that was the problem, and lastly I've wiped the phone twice. Once with a backup and one restore from scratch. Still the drain is persisting.
Anyone else experiencing this or have a solution?
