Hi, I have been playing around with the iOS 7 Beta 2 on my iPhone 5 for a few days now, and I have noticed that once my battery falls below 50%, the usage time and the standby time go blank until the next full recharge. Also, my phone shows my usage time to be a very higher side compared to the actual time that i spend on the phone. Is anyone else facing the same issues as well? P.S. I am using the beta as a clean install.
