I recently purchased a retina iPad Mini - iOS 7.04. It seems to be working fine except for something strange with the reported numbers for standby and usage hours. Rather than giving me different numbers for standby and usage, both are always the same, and seem to just be counting the total time since the last charge was completed. As with my other iOS devices, most of the time the iPad is in sleep mode but the usage readings are not reflecting this. There is no problem with the battery life. I'm getting very respectable operating time and, with sleeping, can get several days between recharging. But the strange and unusable readings reported in the usage function are bugging me. Any ideas?
