On my iPhone 4S, under Settings -> General -> Usage, in the section for "Time since last full charge" both Usage and Standby times are the same. I've been using the phone for 2 weeks now and it always seems to be that way. Anyone know whats going on? Anyone else having this problem?
I did a hard reset on my phone by holding down the sleep button and home button for 10 seconds and that fixed the problem. I wonder if it was some software bug because when I setup my iPhone 4S, I restored from a backup of my iPhone 4 (on iOS 4.3.3) instead of setting up as new.
