My S7 edge has been off the charger for 1 hour and 20 minutes and all I have done is check my email 2 (minutes) and it's down to 92%. Android System and Android OS is taking 70% of the drain.
What am I doing wrong?
some things that might help:
disable Facebook app & other apps you don't use/need
turn off location when not in use
turn off NFC when not in use
when on WiFi turn off Mobile Data
turn off Bluetooth and WiFi scanning (to stop apps scanning in the background, apps scan even when Bluetooth & WiFi are Off)
turn off Nearby Device Scanning
