Hey s3 mini users, i just want to ask a quick question about battery life. So recently i have tried many custom roms (CM11, CM12, vanirAOSP,Dmodv6 and alot more) but i have a problem with my battery life. Roms that are AOSP based like CM11 has horrible battery life (2h screen on time with 10% left). However if i used samsung stock rom based custom rom, the battery is a lot better, i get 3h+ screen on time with 20% left over. So my question is, is this normal for my phone to have bad battery life on AOSP roms?
