"Usage" Incorrect?

I maybe spent 30 minutes on the phone and played music for another 20 and received 1 text.

I've suspected the usage was incorrect but this time I'm certain. Iphone says 4hours 22 minutes. No Way! I have location services off, just in case this was increasing my usage while in standby

It also says my total phone call time, current period is 3 days 29 minutes , which is off by a hell of a lot. I've maybe spent 200 minutes since i bought this thing.

Anyone else having this problem?
