Good Battery Life
Behind the back cover is a 5.661 Whr (1530mAh @ 3.7V) removable battery. That’s 2.9% larger than the EVO 4G’s battery and 7.7% larger than what you get in the iPhone 4.
Overall battery life on the Streak is very good. In 3G web browsing battery life it’s second to only the iPhone 4, and the best Android phone we’ve ever tested. On WiFi it will last 8 hours and 20 minutes, which puts it behind the Droid X and iPhone 4 but well ahead of the competition. 3G talk time is a respectable 7.3 hours as well.
I generally found that I could use the Streak all day without having to charge it until right before I went to bed around midnight.

Video playback isn’t something we always test in our phone reviews but the Streak played a 2Mbps H.264 stream of The Dark Knight continuously for 6 hours and 28 minutes. That’s long enough to watch two back to back movies and a couple of hour long TV episodes on a flight.
