Question About Usage And Standby.........

I have the ip4 and while i love the phone, something seems odd.

I unplugged my phone around 7:40am this morning (NY time) and never used the phone for more then 15-20 minutes max. However, it is saying that I have

1 hour, 4 minutes Usage
2 hours, 3 minutes Stand by

This is not the first time this is happening to me. Just yesterday I had a usage of 30 hours and 42 hours stand by lol.

Does anybody else share this situation? If so, is there a fix? I'm on 4.1 JB by the way.
