The Sprint HTC EVO 4G Reviewby Anand Lal Shimpi on June 28, 2010 6:04 PM EST
There’s no other way to put it: the EVO 4G has terrible battery life. It’s worse than the iPhone 3GS, worse than the Incredible, worse than the Nexus One and far worse than the iPhone 4. If you travel at all, this is not the Droid you’ve been looking for. All of our battery life tests were run from a clean boot with no extra apps downloaded/installed in the background. We didn't forcefully remove anything that shipped on the device however. This is representative of the out of box experience you'd get from a brand new EVO 4G. WiFi and 4G were disabled unless they were in use.
|HTC EVO 4G||Apple iPhone 3GS||HTC Droid Incredible||Google Nexus One|
|Wireless Web Browsing (3G)||3.58 hours||4.82 hours||2.83 hours||3.77 hours|
|Wireless Web Browsing (4G)||3.58 hours||N/A||N/A||N/A|
|Wireless Web Browsing (WiFi)||7.77 hours||8.83 hours||5.23 hours||5.62 hours|
|3G Talk Time||3.95 hours||4.82 hours||5.82 hours||4.67 hours|
|H.264 Video Playback||3.63 hours|
Continuous talk time is just under 4 hours. Wireless web browsing? 3.5 hours. The latter is actually surprising given that I measured 3.5 hours on both 3G and 4G networks. According to Sprint when the phone is stationary, power draw on both 3G and 4G should be relatively similar. When searching for a 4G signal however the battery life should be considerably worse, which is why many EVO owners resort to turning off 4G when they don't need it.
Video playback is also pretty bad. While the display is great for watching movies, even in airplane mode with the display cranked all the way up the EVO 4G only lasted 3 hours and 38 minutes in our H.264 playback test. That's not much better than most notebooks.
WiFi web browsing is actually realy good, at nearly 8 hours if you can stay off the cell radio you'll actually do just fine with the EVO 4G.
