I'm seeing better battery life since 7.1.2
It is a fact, that the CPU has a load between 1.5 and 3.5% while on 7.1.1 it was always between 5 and 14%. I've never seen my CPU on a lower load then 5% earlier.
Let's see how this goes the next days.
I'm on iPhone 5, iOS 7.1.2
Agree, very fast on my 4S as well.This has been a great update for me. With 7.1.1 everything was very choppy it was making me want the iPhone 6 when it comes out. My 4S is suddenly much quicker with 7.1.2. I know it's not as fast as a 5 or 5S, but it was way too slow with 7.1.1. Funny thing is my wife's 4S was ok on 7.1.1.
Oh well, happy iOS user again.
