When I first got my S7 the battery seemed to be draining pretty quickly, being totally unable to get through a full day without needing a recharge. In fact it would get down to about 20% within 7 hours. One night I charged it to 100% before bed, and then left it off charge, and it used up 15% overnight. I looked up some other people's reports, which seemed to suggest that the normal battery drain overnight should be closer to 5%. In fact on the "reviews" section on XDA, a lot of people seem to say that 1% overnight is more normal. I do use the AOD though, which I hear might use up 1% per hour? so I should be maybe getting between 8% and 10% overnight I guess.
I have done a full factory reset, thinking that perhaps it was being caused by an app or setting that had transferred during the NFC auto transfer process, so I did a clean install of everything, followed by wiping the cache. Fresh tidy install. Battery definitely seemed better, but still not great. I did another test last night, a shorter one but still should be enough info for people to help. (hopefully).
I've included the screenshots, which show a 7% drop in battery in 3.5 hours, so a typical 'overnight' is still going to be about 15%, way higher than 'normal' apparently.
I do leave everything running overnight, but from other user's reports that shouldn't matter. I have wifi set to turn off on sleep unless charging. Doze seems to have worked this time (which it wasn't before my factory reset), though it doesnt seem to have helped the battery drain much.
The weird part is that the built in battery app is saying GooglePlayServices is draining a lot of battery, but GSAM seems to think it hardly used any battery at all....

My main reason for chasing after this is that I have just come from an xperia Z5 compact, which will happily get me through a day at work and to bedtime with 40%+ battery left, and could potentially last through two days. True, it has a smaller screen, but then the S7 has a bigger battery. Any help is greatly appreciated.
