> backstory, I got a Samsung Tab S6 used, wiped it and installed LineageOS 20 and I'm using for a couple of months. the battery kinda sucks. granted, I have like 3-4 hours SOT/day but a 7000 mAh battery should last a couple of days; pure guesstimation, I had an iPad some years ago and that thing lasted for eons.

> if I leave it overnight with 10ish% battery remaining and battery saver on, it's dead by morning. that sort of drain can't be normal? on the other hand, I don't have google services so every app has its own running service - syncthing, KDE Connect, Allcast, Jellyfin Player, etc.

there’s the problem with religion: you allow random fantasies to permeate everyday life and it’ll inevitably spill over.
case in point: the fantasy that there’s a good-guy backdoor, unaccessible to bad guys.
so, demand away, preferably at the same place you entertain all other fantasies, like theaters, cinemas,
tax-exempt criminal conspiracieschurches, strip clubs, and the like.
