My power goes quick and I don't know why (no, not from Pokemon go ;-). I installed GSAM and it said cloud uses 15% of battery. Surprised me. I looked at the cloud icon under what to back up and nothing is checked (i.e., back up nothing) and even after that "backup only at night" is checked which should back nothing up and only when my phone is plugged in. So how can the cloud still be using 15% of battery? This is a Galaxy S4 and yes I did just recently put in a new battery.
