iPhone iOS 6.0.1 - Battery % Indicator froze on me

[KeepCalmPeople]

Had my AT&T iPhone 5 for a couple of months now. Have not updated to 6.0.2 yet, and I'm not sure if it would change the behavior I saw today for the first time.

I last fully charged by phone yesterday evening. The phone was unplugged all night and morning, and at lunchtime I watched 25 minutes of Netflix over cellular (LTE). The % indicator stayed at 100%. Out of curiosity I restarted the phone and the % indicator then showed 42%.

Anyone else seen this bug?

You need to calibrate your battery: drain it until it shuts down by itself. Then make a full charge.
