I couldn't find if this has been covered before but I've been noticing that my iBooks app seems to be a little piggy when it comes to battery usage. With. O other apps open I've been Using 15-20% an hour using just the iBooks app. Today I pulled my iPad off of charge and it was 100% and after just about an hour and a half of reading I was already down to 74%. Normally I average a normal 10% an hour web browsing and playing some light games but this is nuts. I typically average 1% every 6 minutes but while having iBooks open it drains at a rate of about 1% every 2.5-3.5 minutes. Is there any way to fix this or a different app to use? I've tried turning brightness down and everything I can think of. This is on an iPad 2 32gb that I've had for less than 2 months. Also I do a deep cycle charge (drain it to below 5% then let it charge back up uninterrupted) every couple weeks or so. I have never had any problems except for this.
