iPhone 4S Battery Seems Okay To Me

Bizarre thing battery life, two identical users can have such wildly different experiences with the same device.

Here's my iPhone 4S at the end of a busy day, with 43% battery remaining. Yet some people are struggling to get through a day on a full battery. That's over fifteen and a half hours of standby and five hours of use with both Bluetooth and Wifi left permanently enabled and all notifications enabled.

Not too shabby in my book...
