I don't think I've ever seen any Usage or Standby numbers. It always says that it's not fully charged yet. The problem now is that I'm in Canada, will they still honour their warranty. I didn't do any hardware unlocking, so the case was never opened. and software can be very easily virginized.
I've charged it with both USB and wall charger overnight, and it still always says "Usage times will be displayed after a full charge".
Edit: Does usage data get cleared after a hard reset (Home/Sleep button hold)? Maybe that's why I've been missing my numbers, I'm using a jailbroken phone, and every now and then I have to reset, or reboot/respring after an update or install.
Edit 2: I just charged my phone overnight, and in the morning, I got a plugged icon, 0 minutes in the usage meters, and NO glow. weird.
And i've been using my iPhone for about 8 hours a music a day, 2 hours of browsing, and maybe 5 minutes or so of talk time. and by the time i get home, i normally still have about 40% left.
