I have noticed since I jailbreaked that the usage & standby time no longer works. After it fully charges it shows 0 minutes for both but then when I recheck it, it disappears & shows the - for both. Wondering if this has happened to anyone else?
Recharging your phone to 100% will reset the time to 0 and it will begin to track it again. Until you respring next, that is.
You must remember not to respring if you want to track usage time for the entire use of a battery cycle.
much better explanation. thanks
