10.1.1 Battery Drain

The new IOS update on 6S Plus is killing my Battery. On a normal day of phone use, when I leave the office my phone would be between 50% to 65%. Since the update I have to charge my phone about 3/4 through the day. I have had this phone for almost a year now, I have not changed any settings. I did not all of sudden start using my phone more. Anyone else having this issue since the new horrible update has went out.

Apple what are your plans to look into this issue so many loyal iPhone users are having. Is it a system issue or is apple going to pawn it off as battery going bad? The long battery life of the iPhone is one of the great things about the iPhone. However, when you spend $799.00 for a iPhone i would hope the battery would last longer then a year.
