I got my s7 new from Verizon directly. Battery life was noticeably horrible.After a week or so of trying to figure out a fix, I got fed up and returned it. Got a new s7 and same problem. Previously had an s5 and regret ever "upgrading". In this case, downgrading.  So, after getting new one, thought t was just me, thinking there's no way 2 phones could be bad...unless the gave me the same one back. So dealt with it past few months. But recently seems to have gotten worse. My samsung s5 would last at least a full day, if not 2 on a charge. The s7 same use habits and apps if I'm lucky a couple hours.  For example, charged full overnight, took off of charger at around 7am.  At 11:00, was down to 15%.  Wifi off. Not doing anything but sitting in my pocket.  That seems not right...any suggestions.
