I was looking on the AT&T website on the info they put for the Titan. The preliminary specifications as well as those found on HTC indicate an 11 hour talk time. Yet, on the AT&T website they have it clocked at 4 hours. The talk time of a device does help you gauge how long the battery will last even though you may not talk all the time. I don't know what this means but I'm hoping it is a typo or AT&T is wrong.
