There has been much talk of battery statistics with varied usage. Can anyone give an idea as to how much battery life is being used with video only (or nearly only) on the 3G phone? I ran a test earlier today: Started with a fully charged phone and ran video with headphones and volume set at 25 percent for 2.5 hours and used about 50 percent of the battery. Brightness was at about 50 percent as well. Does that seem normal in comparison to other folks' experiences? It seems that it was a huge drain in my opinion. Anyone?
