Thanks to everyone. I solved the problem when somebody told me to calibrate the battery.
is still a matter of debate, but it seems that it does need to be calibrated at least once.
Calibrating the EVO battery was actually specifically recommended by HTC a few weeks ago, but the topic has resurfaced in my inbox within the past few days, so I don't want to let another day go by without passing it on.
The method sounds ridiculous but many people have confirmed that it has nearly doubled their battery life, so it's clearly worth a shot. Instructions below.
This is a one-time only procedure.
Here's a variation of these instructions:
Anyone try it?
I do it all the time. I didn't know it had a name, I just noticed that when I turn off my EVO it goes orange, so I wait for it to go green. It may celibate the phone's sensors, but I don't think it does much for the battery. I get 3-4 hours, then I change batteries. I consider it a small price to pay to have the world in the palm of my hand at 1GHz with a 4.3" screen. -- Sharon
