Anybody else having battery drain issues since updating to 7.0.4? I'm down to 20% after only 7 hours 45 mins as opposed to my usual 10+ before. My usage has not changed much since the update so it's not a new app or overuse. Of course Apple will refuse to address this as per every other battery drain issue. I'm deciding whether to ditch Apple completely from now on because of this shoddy attitude to their software making the device suck juice. Any other views?
