I personally haven't noticed any difference in battery on an iPhone 6 and two different iPads so this may not be a universal problem.
None of the bugs were fixed from 8.2, and they added some more. But they added emojis!!!!!11111!!!!!!!!~~~~!!!!!!111!!!!
Stay on 8.1, unless you're getting a watch.
I think there were no bugs on iOS 8.1. Anybody thinks that the battery life on iOS 8.3 is better than on 8.1?
Seems like plenty of people have the same battery life across different versions. Some will have better battery life in 8.3 than 8.1, others worse. But nothing to specifically indicate one is really better than the other as far as battery life, aside from fairly anecdotal personal experiences essentially that don't necessarily apply to most others.Because of it's strength battery life.
