I got my beautiful iPhone 4 yesterday at bestbuy and in an effort to run it through two full battery cycles I didn't charge it last night so that I would be able to kill it today. I left the phone at exactly 70% when I went to bed and woke up just a bit ago to see that the battery without any use what so ever is at 59%. That's a pretty substantial drop, everything like location services is off as well but I hadn't cleared out my multitasking bar of applications despite them supposedly not claiming battery life. Anyone elses phone do this? What can I do? Maybe in a couple cycles it will be better.
