Battery Life

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.

Battery Life
  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.

    you're missing the iPhone 4 in the battery life and there is only one phone in the H.264 page.

    And I think you need to set your white point properly for the iPhone 4 pics. Saying that's the best picture you can produce is not accurate.

    The iPhone 4 review is next, and the white balance was actually a problem for the iPhone 4 - regardless of where I tapped to sample the white balance pretty much came out that way.

    More on this tomorrow...

    Take care,

    "The size of the screen is really what sets the EVO 4G apart from the competition, and honestly I couldn’t think of a better phone for browsing the web. Loading full websites is a pleasure and the screen is large enough where you can actually read a lot of content, even while zoomed in. I’d be willing to go as far as to say that it is almost too small for the ideal web browsing experience."

    This whole paragraph is confusing and contradicting. You say you couldn't think of a better phone for web browsing. Then say you you can read a lot even while zoomed in, which I think you meant to say out there. Then you contradict the first sentence and say it is almost too small for web browsing.

    I think that paragraph needs a mulligan.

    It would be great if you could include Evo 4G benchies in the iPhone 4 review. Reply

    Yeah, I guess u saw the Evo benchmarks.

    I have an Evo and Im considering a Iphone 4 ( my cousin got one )..

    I posted above the following: ... funny how the Iphone 4 review that Anand did proves Iphone 4 on a "slower" 3g network is consistantly faster then the Evo on a 4G network when it comes to the web .. I guess 4G's Peak performance is theoretically better.. but are Sprints 4G average 4g Speed numbers better then ATT's avg 3g speeds?? ..it would seem not.."

    Sorry just gotta make 2 corrections. The front camera is 1.3 mp and the screen is TFT not AMOLED. Reply
  • Anand Lal Shimpi - Monday, June 28, 2010 - link

    Fixed and fixed :)

    Hmm that was actually a bit confusing, Sprint lists it as an OLED screen and it is very similar to the OLEDs we've used in terms of color calibration but all the data I can find points to a TFT display.

    I thought the screen thing might have been a typo, until I saw there was an entire paragraph describing the "AMOLED" screen. :-/ Reply

    That was absolutely my bad. HTC appears to have calibrated the screen to mimic the other OLEDs, it's overly red. Combine that with the OLED listing here http://shopamerica.htc.com/cell-phones/productdeta... and it resulted in my mistake. I was wondering why viewing angle was so bad for OLED, I should've been more careful in my research there instead of just making an assumption. I will be more careful in the future.

    Thanks again for catching the error early on.

    Take care,
    Anand
