I charged my iphone4s completely last night but when I go to check usage, times since last full charge both the usage and the standby are blank.
Why would this be?
Thanks
happened to me as well. Charged over night, but showed " ---" where it would show usage. Charged the next night, and it was fine. Honestly, I love the 4S but I feel my previous 4 was much more reliable bug/battery wise.
