So after just under a week of using beta 4, I've come to the conclusion that battery life on iOS7 is better than on iOS6. A day using iOS6 on my iPhone 5 would usually leave the battery on around 30-40% depending on how much I used it. However on iOS7 (beta 4) my battery life seems to be greatly improved. Not once this week has my battery fallen below 50%, and today when I plugged it into charge it was on 66%. I reckon the fact that I have Reduced Motion turned on is partly the reason, but has anyone else found that battery life is better than iOS6?
