The HTC EVO is the hottest Android phone for now, but it is plagued by the much debated battery issue. Clearly, it’s a monster of a workhorse, and battery life will depend on one’s usage patterns: you can’t expect a whole lot if you get background updates from social networks every 5 minutes and watch HD video for hours.
But the real divisive issue is battery life on stand-by: some claim their EVO’s die in Sleep mode in a matter of 5-6 hours, while others swear battery life is not worse than that of the iPhone. TechCrunch goes as far as warning people: Don’t Buy The HTC EVO, It Is A Seriously Flawed Device.
Wow, that’s a heavy statement – and I have to disagree, because I had experienced all the trouble myself, than started to research, experiment and went from 5 hours to 2 days standby time.
But I don’t want to argue – I don’t have to. I have proof. Just look at the image on the right: after almost 2 days my EVO still has 40% battery left.
I’d say that’s as good as you can get, from a powerful little computer that happens to allow phone calls, too. 
WOW!
Could you itemize everything you did to achieve this kind of battery life???
Also is this with the new update fixing the facebook sync issue?
And lastly, did you use the phone at all in this time period or was this just a set aside and let it sleep time trial?
Dylan,
Some of the steps are detailed in the previous post I am linking to under “from 5 hours to 2 days standby time”.
It all happened before the OTA update, which came out after I wrote the post.
Yes, I used the phone, not too heavily, but as you see it was awake 3 hours 45 minutes – most of that is active usage.
