My galaxy s6 battery goes from fully charged at night, then off the charger, and when I wake up in the morning it is at 10%! I have google location history turned off, I only have it set to sync my email, contacts, google drive, and photos. I noticed it always says it is syncing my photos even though I have it set to only do so while charging. I deleted the google photos app to see if that might help. I have screenshots of the graph and battery usage. If I figure out how to upload pictures I will. Does anyone else have this problem and how can it be fixed?
