Anyone notice battery life a lot worse on the 6s? Yes I know the 7 is newer and has a better battery but the 6s had good battery life on ios9 and it went bad since ios10. Meanwhile iphone 7 battery life is fantastic. Iphone 7 gets almost twice the battery of the 6s on ios10 and I know this isn't normal, because 6s had similar battery life to the iphone 7 while it was on ios9. Edit: Downgraded to 9.3.5 and the issue is fixed! I recommend you do the same while it's still being signed if you have a similar problem!
