I have a 5s and I love it. But the battery life bugs me. I imagine I should get at least 6.5 hours or more; I have a pebble watch connected to it but still I would only expect that to take away maybe 1.5 hours. So shouldn't I be able to get 6-6.5 hours of usage, rather than just 5? I have gotten 6 hours or more before, but it doesn't seem to be very consistent. I did a complete restore not too long ago and did a battery calibration the the other day; and nothing. My question is, is this normal for a 5s? Is it realistic to expect to get 6 or more hours of usage when I have a pebble connected and use web based apps/safari and other typical phone tasks, such as mail, messages, music, radio, etc.? Is the 5 hours that I usually get average, or is there something up with my iPhone?
