I wrote HTC about some of the problems we have been having with the EVO, namely battery life. Here is the response I just received:

Dear XXXX XXXXXX,

Dear XXXX, HTC and Sprint are taking steps to improve observed battery life. HTC is developing a number of handset software optimizations that are expected to increase device operating times. These updates are expected to be available as part of software pushes scheduled for later this summer. As with any software development effort, we cannot provide an exact date. Additionally, Sprint is working to optimize 4G network settings to improve battery life for customers in 4G markets. I will be happy to go over various setting with you that will help extend the battery life. Traditionally WiFi, GPS, Bluetooth, and display brightness all greatly impact battery performance. With Android 2.1 another feature that can kill your battery are the Live Wallpapers. If you’re using Live Wallpaper just turn if off. Adjust the Brightness of the display (Menu | Settings | Sound & Display | Brightness). By default it is set to auto adjust but you can manually adjust it down. Consider adjusting the display timeout (Menu | Settings | Sound & Display | Screen Timeout). The default value is 1 minute but you can reduce it to as low as 15 sec but 30 seconds. By default your HTC Incredible vibrates every time you press a key. Turn it off by un-checking the box ‘Vibrate when typing’. Menu | Settings | Language & Keyboards | Touch Input | Text Input | Vibrate when typing. If Facebook, Twitter, MySpace, Email, App Updates, or many other things are constantly popping notifications, consider turning some of them off as notifications do impact battery performance; This is done in each app. To also help with Battery Life you can do these steps exactly: 1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well. HTC has received some reports regarding this issue with the screen seperation, and are currently analyzing the potential causes. Most customers are not reporting any issue related to this problem. The issue appears to be cosmetic and should not affect the operation of the device. Additional information will be provided after we finish our investigation of the issue. If you have any other questions or concerns please Reply back to this email or give us a call at our HTC Technical Support Line, 1-866-449-8358. I want to thank you for contacting HTC. In order to help improve our service I’d like to invite you to take a survey at http://survey.htc.com/worldwide, you can also checkout http://shopamerica.htc.com/homebrands/index.htm for more information.

Interesting! I'm going to try that so called battery doubling trick asap!

Dear XXXX, The EVO 4G and the Incredible are having the same issues with the battery, I do apologize for saying Incredible, but I didgive the correct answer. This battery charging regimine is a one time operation, if you need to do this more than once a month, I would talk to Sprint about a replacement battery, but with the batteries we are looking into the issue further. We are not sure why this works, we like our customers have the HTC phones and were looking into forums and found this and it worked on all of our agents batteries, they all gained about 10 hours of battery life with regular use. We have also, tested how long the batteries take to charge and yes, this battery takes about 4 hours to charge, we are looking into this, but it is not an issue that will harm anything. You should be able to charge your battery while sleeping and you should not have a problem with the battery lasting all day, but again we are looking into the battery situation. With the Micro USB cables, most should work, but we recommend HTC Micro USB cables. You can go to shopamerica.htc.com or http://www.yourwirelesssource.com/do/search/searchProduct?search=PCD for accessories for your EVO 4G.

Ok, this battery charging trick has helped big time! I've been unplugged for 5 hours now and I'm at 80%. usually my battery dies at 6 hours. I just noticed my phone is not sleeping. wonder why that is? anyone know how to find out? wonder if it could be nimbuzz or k9 mail preventing it. I'm guessing the battery life would be really good if the phone would actually sleep.

edit: yup, it was nimbuzz, my IMing program preventing the phone from sleeping. damn, i need an IM program that supports push!! facebook push would be nice also.

That's basically like the fix that another user here on suggested. Charge the phone fully while on then turn it off, then unplug it. Once the light turns off plug it back in, It will then start charging again anywhere from 1 minute to 5 min when the green light is back on unplug it and do it all over again do this for about 10 times then turn on your phone and your battery life will be considerably longer.

I'm hoping that is a one time thing to charge all the cells. I get pretty decent battery life now, so I'll have to give that a try when I can find time to keep my phone off for 2 hours.

Will be looking forward to see your results.

If this is something they expect users to do regularly that is just downright ridiculous.

I'd be very interested to hear what their technical explanation behind the charging dance is. Could you reply to them and get some more information?

then wave your phone in a figure eight for 10minutes while on, then a circle for 5 minutes while off, then on again and you will have Froyo installed.

I've been doing this for the past three hours.. It's not working! What am I doing wrong? Can someone please point me to a youtube video showing how to do this properly?

$1.50 to anyone that does... I really want froyo


THANKS!

Definitely going to try this. I'm guessing the "battery is full" circuitry is falsely detecting a full charge and cutting off the full charging current and just leaving it to trickle charge. Doing this procedure repeatedly tricks that circuitry to allow more and more of a charge while also updating the batterystats.bin file to reflect the battery is accepting more of a charge.

But that's purely from minor electronics experience, not sure if there's any other android or htc-specific factors at work here.

Oh, and...
then wave your phone in a figure eight for 10minutes while on, then a circle for 5 minutes while off, then on again and you will have Froyo installed.

wave it in a reverse figure eight and then reboot and the kernel source will be released.

I am a bit disappointed in HTC.
I mean FFS, if your logo is on a phone and the battery in it, at least set it up so we don't have to do charging aerobics to get the battery full.

It seems like they cut corners somewhere..

EDIT: One part that made me particularly rage is this.
Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well.

Oh so this whole time we've been charging our phones halfway??
Why does it seem like they're in our situation, trying random crap to get things working they way they should.
This should not be a damn issue, HTC should be ON this.
If the battery is capable of holding twice as much life per charge then we should be reaping the benefits already, not running around like headless chickens and doing backflips for an extra hour or two..
Sorry for ranting but it just seems like they dont give a fuh

I rescind some of what I said, the second response clarifies that they are working on it, and at least you only need to do this charging method once a month..

    Normal for me. Weak cell signal at office as and twitter/facebook sync. Before doing this, it would only make it 6 hours before i'd have to put it on the charger.
