Ok, does the top on/off switch REALLY turn the phone off? The battery was low when I first got it (yesterday) so I charged it to full, then spent the rest of the day learning how to use all the features. It was at about 86% by the time I turned it off and went to bed. Turned it on just now and the battery is at 1% as if it had been left running all night. It says to just hold the top button for a few seconds to turn it off, right? Am I missing something? I have it set to Airplane mode as I'm using my computer as a wifi hotspot to get online with it without using any data plane time. How can I find out if anything is still running? Edit: Ok, mystery solved. I never saw the slide to power off bar so apparently I left the phone on standby all night. This is my first iphone.
