Okay, to all that were having problems getting the picture of the batter on the wallpapaer to show full charge and getting the usage statistics to reset battery usage to 0 I have solved the great conundrum.
Once the tiny icon in the corner shows the plug icon instead of the lightning bolt, technically the phone is 100% full but the picture of the big battery is not full nor has the usage statistics reset to 0. All you have to do is sit on the locked phone screen, unplug the charger, go to the usage statistic screen, plug the phone back in and in seconds the lightning bolt in the corner should change to a plug and the usage statistics will turn to 0 and begin (again).
Also, lock the phone then hit the power button again to see the full larger battery icon.
worked for me, hopefully it works for you too.
