My S5 battery is worse than s4 and G2. Could it be my Gear 2 watch that's the problem? GSAM tells me Android system is at 30%. I also have S Health pedometer running because I can't seem to find a way to turn it off.
Any suggestions?
go to settings>apps
turn off all the bloat apps you dont use
go to settings>wifi>advanced
turn off always allow scanning , set keep wifi on during sleep to only when plugged in, turn off notifications, turn off smart switch
go to settings>motions and gestures and also air view
turn off everything you dont use (everything for me)
go to the pull down quick settings menu
turn off everything you dont use
i had a few too many drinks and forgot to plug my phone in when i went to bed, i had about 70% when i went to sleep, i was still at like 60% when i woke up
