I noticed that all the apps on my Pixel 8 has the “Allow background usage” option enabled. Didn’t this use to be an opt-in setting?
I’m worried that something got messed up when I had to do a copy from my Pixel 8 (Android 15) to my old Pixel 5 (Android 14) and back to my Pixel 8 again (I had to factory reset my Pixel 8 before sending it in for repair).
It’s on by default for newly installed apps.
It’s one of the things I manually disable for pretty much all apps.
I also use Greenify and disable Shallow Hibernation/Background Free, because those don’t make apps restore any faster (because current phones have sufficiently fast ram/cpu), but it does eventually slow my phone down because I switch apps heavily (I’ve done a LOT of testing with this) and it takes references in memory for page swapping type activities.
