Hi guys. I am rocking CN version of Mi11 Ultra 12/256. It's currently on stable 12.0.10. i have allowed the application for notification and set up the system in my way to be usable by uninstalling most of the chinese ops that i was able to. Now, i can see that the battery drains abnormally it seems that the phone doesn't go to deep sleep. The second highest usage stats is android system.
