Since a while my s4 battery has been draining very quickly, even on idle mode. So i bought a new battery right now and the issue still remains. Example - Battery was at 60% with all apps shut, within 5 mins it became 56%.
Just bought new S4 zoom and over 7 hours on charge it went from 50% to 70% charged. It seems to be draining all the time and the re-charge can only just keep up.
I have turned off wi fi and bluetooth and am not aware of any apps open. Any suggestions as to what might be causing this. Which says battery life is outstanding!
