I had this phone for 5 days. I noticed immediately in settings that in the "Usage" bar it says how many hrs talk/standby the phone has been used. Thats a cool lil feature I thought to myself. Yesterday I saw there there wasnt the usage meter. So I click on Usage and it says "Usage tmes will be shown after iPhone is fully charged". I charged it fully, I see the usage times again - good deal. Today I used the phone a lot (iPod, watching vids, etc) and ran the battery down to 1/2. Now the same "Usage times will be shown......" msg is back. Is this normal for the usage meter to disapear even when the battery isnt fully used?
