If you're talking about Standby Time and Usage Time the phone needs to be charged to 100% and then taken off the charger before those stats will be accumulated.
 
Hmm...

Yea that's it but I charged it last night to full and it's not showing anything

My guess is that you should force reset your iPhone by pressing the lock button and home button until apple logo appears, then let go of both buttons... Wait for phone to boot up. Then plug phone back in until it shows the fully charged icon again. Then unplug and check your usage stats.
