Last night I made sure my iPhone was charged fully before I undocked it and went to bed. I turned off wifi and bluetooth. I did not listen to any music or get any calls, e-mails or texts all night. I get up this morning (about 8 hours later) and the batter meter is down probaby about a fifth of the way. Is this normal?? Actually I just went to the usage screen and it says 8 minutes usage and 9 hours, 33 minutes standby since the last full charge.
