So my iPad 3 was at 95% charge this morning. I played 'Wheres my water?' for 2 hours and its down to 65%! The brightness was on medium. I cannot get my head around this. From my experience Im looking at 6-7hr battery per day, OK that's about enough but my iPad 2 (let's face it, a totally different machine) gave me ~10hrs for the same usage patterns. So now im going to keep the iPad 3 screen even dimmer and use airplane mode when i dont need the signal. The fact it takes forever to charge doesnt help. I really hope Apple improve the power management (seriously down clocking the CPU/GPU etc) with the next iOS update. The retina is nice but we seem to be paying a hell of a price on the battery life. I was not expecting that.
