I've had the phone on for 5 1/2 hours from a full charge last night, and I just got a 20% left warning message? Might it have been because I jailbroke it twice last night to get the installer app on it? What is the recommended first time full charge? And when charging does itunes have to be opened or any usb port is fine. Seems I'll be charging this thing way more than I expected. Blackberry used to make it a good 10-12 hours before it needed a charge and that was with me chatting on messenger all day. I'm also thinking the web based messenger since it kept searching for a connection which I believe is done intentionally was also putting stress on the battery, so I went back to fringe if that makes sense. Any input would be appreciated.
