I read some threads where people had to continuously turn it off and on to get a green light. You shouldn't have to do it more than once to get a green light on both on and off mode. Meaning while the charger is plugged; charge till it's green, turn it off until it's green, then turn it back on, unplug, and you're good to go.
Now by turn it off you mean hit the pwr button at top right does that turn it fully off it doesnt pwr cycle so wondered if the was another way of powering it off that I didnt know about please inform me

Use the button on top and choose to Power Off. If your light only stays amber for a minute or so when it's off, your battery is charging just fine and you don't have a problem. If it stays off for longer, you had a gap between what the Evo software thought was full, and what the battery level actually was, so when you turn it back on and off again, the light should only stay amber for about a minute.
Don't do it over and over and over, unless you are itching to kill some time today.

The charge on and off procedure has really helped me alot especially for those who losing a lot charge after removing phone from charger.
I consider myself to be an average to light user.
My phone has been off the charger for about 14 hrs currently showing 50% bat. remaining.I have watched some sprint tv, phone calls, checked e-mail and did some texting.

This thread is truly a must read. After downloading stuff and whatnot I was starting to get bad battery performance, obviously because all this stuff was running in the background and the phone was wqorking too hard. I followed all the suggestions here (and uninstalled appkiller) and now the battery is doing great.
The CDMA trick works awesome. What a difference this small fix makes. I'm a heavy user and I'm now currently at 7 hours 15mins on battery still with 50% battery left. I'm usually charging my phone after 4 hours of heavy usage, but now I still have 50% left. The first 3 hours of usage were heavy surfing the web, watching videos, and gaming. The rest of the day were standby and random usage throughout the day. Hope HTC will send update patch to make this permanent. Thanks to who ever figure this out. Who knew my phone was wasting battery trying to connect to a GSM network.

My, the camera sure does drain though. I haven't had any real battery problems yet (thanks to all of you providing good guidance). But, a few flash based shots with the camera, and the battery was hit HARD.

Yeah, I accidentally flipped the camera on and stuck it back in my pocket a couple of days ago, and when I checked the battery stats, the camera was responsible for about 40% of the drain. That's nuts.
By the way, the CDMA trick has done wonders for me too, mainly at work where I have weak signal due to the location of my desk.

Pulled my Evo off the charger at 930am this morning. I didn't really do anything on the phone. Maybe 10 texts. Phone died at 545pm. I think my awake time is what is killing it. I also went in and killed all apps that i could. I just did the GSM/CDMA trick. Will post my results tomorrow night. I got the phone on Thursday, so i have only charged it 3 times. Im hoping as i "break" in the battery that my times will also increase.
I have these running all the time.

I use my phone so much that I usually have to charge it 2-3 times a day. I went on eBay yesterday and found two batteries with a battery charger for $15!! Once it arrives I hope to only have to charge my phone once.
That is only going to add to your frustration those batteries are fake, labeled as 1500mah but actuall 800-1000mah so they will significantly decrease battery life on the phone. It is classic case of you get what you pay for.

nope. Did the HTC fix and the CDMA and today I had 4.5 hours of medium use and my battery died. I am so sick of this battery issue. THink I am taking it back .

While it is still pretty much 'up in the air' as to if the 'phone off, on, off on...repeat till green' method works or not, I did perform the task as well as disabling GSM to CDMA mode.
My battery life yesterday was actually really good. Around 8:00 last night I was really chompin at the battery. SNESOID for a while, Sprint TV, Web Browsing...a lot. Here is my outcome for yesterday. I wouldn't say I had high usage through the day, but I was still using it a bit.

Anyone else not getting their Gmail in a timely manner after doing the CDMA trick? I have Gmail in my account, but not on my phone. Not sure if they're related, but the CDMA trick is the only change I've made to my phone, and it was working fine before I did it...
This is using the gmail app btw.

I owe all you guys a beer. And I was ready to take this back

I've sent myself a couple of emails to my gmail accounts and seem to be getting them pretty much instantly.
Preparing...
With the phone in the on position.
Fully charge the battery with the phone on... (until the led turns green.)
Once the led turns green, unplug the charger until the led goes off.
After the led goes off, plug the charger back in. When the led turns green , power off the phone.
now.... with the phone fully powered off...
1. Unplug the charger.
2. Wait until led goes off.
3. Plug charger back in until the led turns green. When it turns green, unplug the charger again and go to step 1.
4. repeat steps 1 and 3, 10 times. This may take anywhere from 30 seconds to 30 mins per cycle. Typically only about 1 minute. though.
Mods I made an error and left out the plug in and out of the charger cord can some one modify this post please??
Sorry for the inconvenience

Ten times? That seems a little extreme. Shouldn't you only have to do it twice -- once to calibrate, and then one more time to double-check? If subsequent cycles are lasting only a minute, then you're already calibrated.
I could be wrong, but that would seem to be logical.

I have been getting really good battery results right out of the box....until today. I just got 5 hours and it is about to die. Changes made....none. I just don't get it. It almost acts like it didn't take a charge over night, which is odd as it showed a full battery when I unplugged it, green light and all.
EDIT: OK, apparently, I had G-Strings guitar tuner running in the background the entire time. I figured when I exited it, it should have closed but I guess it doesn't. I had to force quit it, and so far I am back to decent battery bleed.
