So I've been twinkering around with my new iPhone 3G for the past few days especially when it comes to battery life. I have shut off the bluetooth and wifi and currently have Push off with e-mail check every hour. At the Keynote Jobs said that talk time on EDGE with the new iPhone would be 10 hrs as opposed to just over 5 on 3G. Therefore meaning that the battery on the 3G is more efficient (or larger) than the original iPhone. Yet today, I disabled 3G from the time I took my phone off the charger and the phone STILL didn't last anywhere near as long as my original iPhone did. It seemed as if it didn't make a difference having 3G turned off. This is with normal battery use just as I ran on my original iPhone. What gives? Anyone else notice?
