    I think its because a jailbreak tweak is disabling or breaking it.
    It says usage: -
    stand-by: -
    usagetimes will be updated after the iphone is fully charged.
    well i charge every night to 100% but the iphone wont display it.

    any known fix or cause?

    This is conpletely normal. It does this when you're not jailbroken too. Any time you respring or reboot your device you will lose track of usage and standby times. If you want time to be recorded for an entire battery life cycle, just don't respring or reboot your device.

    Rebooting doesn't clear the timer only resprings and crashes to safe mode clear it. Every time you update or download something in Cydia you are usually asked to respring at the end of the install and it's then that the timers are wiped.

    Instead of hitting respring I close Cydia with the home button then hold the power button and reboot like that, you don't lose the usage timers then. Hopefully one of these days one of the smart arse tweak developers will figure out how to write a tweak to restore the timers after a crash or requested respring :)
