Is it possible based upon previous history, to try and plot the battery life and talk time of the next iPhone?
Maybe...
iPhone First Gen - 3.7 V, 1400 mAh (8 hours of talk, 6 hours Internet)
iPhone 3G - 3.7 V, 1150 mAh (5 hours talk, 6 hours internet)
iPhone 3GS - 3.7 V, 1219 mAh (5 hours talk, 5 hours internet)
iPhone 4 - 3.7 V, 1420 mAh (7 hours talk, 6 hours internet)
iPhone 4S - 3.7 V, 1,430 mAh (8 hours talk, 6 hours internet)
iPhone "5" - 3.8 V, 1440 mAh...
Given the history and what has done with small batteries, I am guessing 7 hours of talk time and 6 hours of 3G/HSPA+ internet, and 5 hours of LTE internet use.
