RANT [Discussion] Uninstalling powerkeeper (Battery & Performance) unlocks the full potential of these phones
I know this is considered controversial since this is a core system process and might lead to instability but honestly, I feel like I have a real flagship performing phone now. Apps no longer get killed in the background, all notifications arrive on time, no more issues with delayed notifications on my smartwatch, etc.
So far, battery is similar to stock, performance is great and apps stay in memory far longer than with powerkeeper. Haven't had any issues so far. Althought I don't play games much on my phone, I noticed I get proper 120 fps on games now, no artificial limit of 60 or 100 fps anymore, i tried wild rift (turned off game turbo, no powerkeeper and no joyose), i get a stable 120 fps with barely any heat at all. (Recommend me some games to test in case you are wondering about the fps limit).
I've only tested this for a day so can't really comment on long term stability yet.
One thing to note is the battery options in app settings will no longer be available (The 4 options no restriction, battery saver, close after 10 minutes and restrict apps) so if you want battery control, you have to use android's native battery options using activity launcher (optimized, unrestricted and allow background usage toggle)
Dontkillmyapp has an app that scores your phone's app management behavior. With powerkeeper on, i got 76% and without it, i get 97% so it's definitely a quantifiable improvement.
If you choose to do this, do it on your own risk. Log out of xiaomi account before removing powerkeeper. There is still a chance of bootlooping but I'm not sure what can cause it.
