I do not know why that is. If you have an Apple Store nearby, make a genius bar appointment to let them diagnose the problem for you and possibly fix it. It's possible, that a restore could remedy the problem, but I can't say for certain.
If not using the OEM charger, the one you're using does not provide sufficient current to charge the device while it's running... use the OEM charger, or a 3rd party charger that is specifically labeled as being made for Apple products...
