My pixel 5a with GOS w/o google services struggles to run 36 hours with single charging and average screen time. My brother's 5a with stock ROM is running at least 4 days, while he's having the same set of apps installed and he's having less screen time. My biggest consumer is Signal (set to unrestricted). On my previous phone with LOS w/o google services and with smaller battery I had 3-4days with single charge. Is such short battery life observed by others as well?
