updated my iphone 6 to 8.1 from 8.0.2 5 hours ago and i noticed a big battery drain with normal use. anyone else experiencing this?
I don't get why people don't realize this. After every update, Apple turns bluetooth back on and sets the screen brightness up to high. That is the reason for battery drain.
So...if you don't use BT, make sure you turn it back off. Also check your screen brightness level.
