Sorry guys but this isn't accurate. Mine was already CDMA (Auto), but the moment you do menu->select radio band, it's just erroring out and defaulting back to GSM (Auto).

Try not hitting menu->select radio band, and just scrolling down to the end of the page, you'll see it's already at CDMA (Auto). Placebo effect only, at least on the EVO.
[EVO 4G General] AssassinsLament:
The best battery life trick is to go to Settings->Accounts & sync, and turn off Auto-sync. Then just in case, change the update schedules on everything you can to manual, then also make sure you turn off whatever you aren't using at the moment (mobile 3G, wi-fi, bluetooth, gps). Also, go into google "talk" and set it not to start up at boot, and sign off (cause it's always on if you don't do this). At home, I usually turn off 3G and leave on wi-fi, and turn off everything else. It's a smart phone, it has a ton of features that auto sync and auto update, just figure out what you need and don't need and turn off what you don't need. Like weather updates, like contacts and so forth. Those can be updated manually.
[EVO 4G General] scriptx:
Stupid bugs like this make me mad. My TWS is over 50% without following these simple steps to set it to CDMA (prl). This must be done at every boot. I haven't found anything to support that this has been reported to HTC, though it should be!

Great find by the way.
[EVO 4G General] formulabird:
My time without signal is 81% this leads me to believe that my phone is always searching for signal which means it would drain faster. There has to be some kind of fix for this
[EVO 4G General] GReddySetGO:
I just did this, mine was set to GSM auto, I changed it to CDMA auto. Will report back if it made a difference or not.

Regarding the CDMA vs GSM defaults.

My wife's EVO is a lighter black color with more texture and her's was set to GSM by default. Mine is blacker and smoother and it was set to CDMA.

If I had only 1 EVO I wouldn't have realized there was any difference but in my case I had 3, 2 dark black, 1 light black and the light black one was set to GSM.

Coincidence?

To those with lighter grey versions, were they set to GSM?

(Dark Black version [CDMA by default])

(Light Black version [GSM by default])

(Top Light Black (GSM) | Buttom Dark Black (CDMA)
[EVO 4G General] mrono:
They look like two completely different qualities, yours looks older and more used, your wifes looks newer

This is what mine looks like, was set to CDMA
[EVO 4G General] AssassinsLament:
Mine was the blacker smoother backing like yours. And was set at CDMA by default also. I haven't really experienced bad battery life nor any of the other issues people are having (knock on wood), but I'm probably a victim of the 30fps since i think everyone is affected by that.
[EVO 4G General] ipractice:
This isn't really a fair argument because when people originally did this on the Hero, this same glitch was happening but people reported significant increases in battery life. Check this thread (http://xdaforums.com/showthread.php?t=651848&highlight=tws).

My time without signal is 1% but I'll try this fix anyway because i'm seeing significant battery drain recently. Also, my cell idle was at 32%, higher then anything else on the list.
[EVO 4G General] mugen939:
I did this last night. My phone was set to GSM auto. So far my battery has been boosted big time!! Normally when I unplugged my phone after about 30 minutes without any usage at all the battery would be at 95%. It now stays at 100% even 2 hours later without usage. Awesome little trick. Hopefully this issue gets fixed in an OTA though.
[EVO 4G General] infideler:
Worst thing I ever did. It had been set correctly already, and when I followed instructions and I changed it to CDMA again, the battery drains in about 3 - 4 hours.

Anyone know if performing an entire device reset will reset that submenu as well?
[EVO 4G General] danknee:
Will you please go to settings, about phone, hardware information, then see which hardware version your have? I have version 3, mine is the smoother black and was set to CDMA. I am curious if the version 2 or 1 phones are the ones set to GSM.

Mine was set to GSM, I changed it and so far have seen a significant Improvement in battery life. Neat trick. Also anyone know why Google talk always seems to sign me back in even if I have the automatic sign in off. I don't ever use this and it just nags me to see it running. Don't know if its actually using battery but I just don't want it running if I don't use it. Thanks
[EVO 4G General] fone_fanatic:
my co-worker has an evo and keeps complaining battery life, so i came here and found this thread. His cell standby was at 21%. Went into the testing menu and his was set to CDMA auto (prl)

Then we found out that the evo and the htc rhodium (touch pro 2/tilt 2) use the same battery!

So he's gonna go to an at&t store and buy the bigger sized tilt2 battery that fits without changing the battery cover.
[EVO 4G General] L_Mo:
Was set to GSM here...

By the way, can someone please describe how to look up the TWS? I would like to see if I'm actually improving things...
[EVO 4G General] kjones2k1:

[EVO 4G General] ReFLeX135:
Version 3 set to GSM. After reboot it stays on CDMA though.
[EVO 4G General] GReddySetGO:
Version 2, and mine was set to GSM.

I did this fix and it has improved my battery tremendously!! Under normal use, I would have to charge my phone within 6-10hrs. As of right now, my phone has been off the charger for 6hrs, and it just turned to 80%. I think it would still be at 90% if I didn't accidentally leave 4G on for like 15mins earlier. BTW, my TWS is down to 0%

I can easily get through my entire day without worrying if I have a charger with me. I think under conservative use, I could get to charging it every other night instead of all day long.

GREAT FIX!!! Thank you, OP
[EVO 4G General] GReddySetGO:
As explained in the first post, I will restate it.

From the HOME screen, Menu > Settings > About Phone > Battery > Battery use > Cell standby

At the very bottom of the Cell standby screen it will show your TWS. I was at 40-50% before this fix, I am now constantly at 0% TWS.
[EVO 4G General] Wasney:
We had the exact same issue as this in the Hero forums. It is needed to be changed everytime you reboot on the Hero. For use it would say it was still CDMA when we rebooted, but would actually revert back to GSM.

Check your TWS, let me know if after a reboot it is still at 0.
[EVO 4G General] ufkinloveit:
i read on androidforums.com to do this and a factory reset. I had the OTA update and the phone was already set to CDMA but everyone in the thread made it a point to do the reset so i did. The battery has improved drastically, so thats another thing you guys could try. The only dawback is that it erases all apps and your settings to like the phone was out of the box.

[EVO 4G General] danknee:
My TWS has been consistently at 1% with the Evo, mine was already pre-set to CDMA auto. On my Hero I had to pull the Force Close trick every reboot or else it would be around 15% TWS.
[EVO 4G General] neonsector:
yeah it increased mine's at least 4 hours.
[EVO 4G General] Roman G:
I have version 2 and set to CDMA by default:)
[EVO 4G General] carlosruizano:
No TWS

I have looked at the cell standby screen and I don't see a Time Without Signal stat. All I see are "Cell standby" and "Time on". Am I missing something. Also I have the phone set to "Sprint only" under the roaming settings.
[EVO 4G General] martouf13:
I noticed mine was set to GSM as well. The TWS was 50% before I changed it, WOW... I will have to wait and see how much better it does after a full charge! This is a serious problem that needs to be fixed... Doesnt seem like it would take much to fix this kind of an issue...
[EVO 4G General] martouf13:
Another thing, why in the world would you have a phone that is CMDA search for a GSM signal?

Just another update.... My phone has been off the charger for close to 24hrs now, and my battery is still going at 40% remaining. I have used the phone as I normally do, made some phone calls, texted, played games, emails, even used 4G for a little bit.

So I am VERY happy with this fix, this has more than DOUBLED my battery life. TWS is still at 0%
[EVO 4G General] baiatul:
I followed the steps, even though I had already CDMA auto. As he said, one of the steps crashes, and after it recovers, the GSM option is selected. I think that's a bug. I had to manually reset it to CDMA auto.
[EVO 4G General] norkoastal:
Is this setting sticking for anyone after a reboot?? I think we should try to communicate if there is a permanent method to keeping the phone set to CDMA. I ws on Release 2 with the GSM setting.. Does full Root enable more access to make this change sticky?
[EVO 4G General] JQMUSTANG:
questions

My evo was set at gsm, i switched it to cdma as suggested and I have to say that my battery life is worst. I just unplugged it from the charger at 96% and 1:30 mins later I was at under 65%. I have wifi, gps and blue tooth off. Help!!! just pulled the battery on it, let see if its better after the restart. I noticed that my TWS was like at 15%, thats not bad considering what i have read on here. Also, noticed that after the hard reset my phone was still registering cdma aut prl. Im sooo frustrated
[EVO 4G General] flexte:
i didnt hit select radio i just scrolled down and it was on gsm.
[EVO 4G General] JustinChase:
I only show 6%, so I might not have the "problem", but wanted to provide full disclosure :)

I don't understand why you want to "select radio band." and force the force close.

If you just select "Phone Info" you can scroll down and see the "Network Type:", which in my case is CDMA - EdVo rev. A

and if I scroll down I see the "Set preferred network type" and CDMA auto (prl) is selected.

if I select radio band and do the force close and go back, it then shows GSM. this happens every time. so, why make it force close? if I just restart and go back into the testing menu, it defaults to CDMA.

maybe others default to GSM (which makes NO SENSE in a CDMA phone software), and this will help those people, but my wife's phone has battery life issues and hers is like mine, defaults to CDMA.

Just throwing that out there for you :)

[EVO 4G General] JQMUSTANG:
Just an update on my original post. as I mentioned earlier my evo was set at gsm, when I changed it to the cdma setting recommended my battery drained by 40% in 1 hour and a half. I switched back to gsm after recharging and 4 hours later ive gone down about 15%, not too bad. Am i the only one this happened to?? The gsm is actually working much better for me
[EVO 4G General] pecosROB:
I had updated my PRL and when I did this "trick" it showed it was on GSM only.

I thought this phone had no GSM capabilities due to hardware (the iFixit teardown didn't mention a GSM radio, did it?). Why would it even have an option in the software? Is this because this is an Android option and not specific to the hardware/device?

Same Problem

My phone already had the CDMA Auto selected, and battery continues to decrease rather quickly. Tried changing all autosync to manual, but battery still dries up in a matter of 3-4 hours, I have good signal at my job, GPS, Gtalk, and other apps are turned off. This really isn't a good way to start off with a new phone, waste time trying to find out how to keep it on...

Good luck, I'll keep reading...
[EVO 4G General] Rose4uKY:
I'm confused now cause I didn't even notice what mine was on when I went into that *# screen. My friends was on CDMA and he didn't do any of the menu select radio. I did the steps it said to on here and hit that radio select whatever it was and let it force close and then I saw GSM. Well didn't someone say everytime you do that it goes to GSM? So maybe mine was on CDMA to begin with? I don't know! I didn't pay attention I Just did the select radio. And then I did reboot and did the steps over again and still saw GSM. But I was hitting select radio again. But then my friend said he got Network and his was on CDMA and he didn't do any other steps and that is when I went back and changed mine to CDMA and hit home and didn't hit the radio select button anymore now mine is on CDMA and stays that way when I reboot. Mine also is hardware 2. My friend has Hardware 2 also and his was on CDMA. He got the network app. So I told him not to do the select radio option if his is on CDMA to leave it. And I am leaving mine.
[EVO 4G General] splink7007:
After some testing of this I found that after you do the #* and phone info. Mine already shows cdma auto. But when you hit menu and select radio, after the fc. It did say gsm auto. But even if you don't reboot your phone and do it all over. It will show cdma auto in the general phone info, but when you hit menu and again the fc happens. Right back to gsm auto. I'm thinking that what it says at the first phone info area is correct. And when you hit menu and select radio, after fc, it goes to gsm auto. Maybe the fc sets it back to gsm? Just throwing it out there. Maybe someone else can test as well.
[EVO 4G General] unclepain:
Mine does the same thing- It's on CDMA by default, and when you choose to select a different radio and the app crashes, it comes back up on GSM. Unless you are on GSM when you first open up the testing app, I don't see why you would want to do this. Seems to me that crashing the app defaults you back to GSM.
[EVO 4G General] topdawgn8:
You're right. I notied this the first time I did tried it. I'm at a loss of words for battery life. It's fine in sleep mode...it sustains with no noticeable drain after a half hour; however, I drain about 3-4% every 10 minutes when it's on with very light usage. I did notice the processor pegs around 990 Mhz when utilizing the touch interface. You can sit there and watch the monitor peg with a couple of little swipes.
[EVO 4G General] healthpellets:
i have CDMA Auto when i pull it up.

i also, on a typical day, only have 1%-3% time without signal. so probably not going to do much for me.

[EVO 4G General] nYdGeo:
Doing this, removing the big people widget, keeping 4G, Wifi, BT and GPS off, with very light usage I can get 6 to maybe 8 hours on occasion. Maybe 45 mins to 1 hour more.
[EVO 4G General] richse:
My TWS is generally under 1% because I get good signal around the city. If your TWS is higher then your phone is searching for signal and eating the battery. This will happen even if you have CDMA set in the testing menu. When your signal sucks your battery is going to die, its pretty much a fact of cell phone use. Turning on airplane mode is about the only fix you will find.
[EVO 4G General] richse:
This was shown on the Hero to just be a glitch that occurs after the Testing menu crashes. It does not mean your phone is on the wrong setting or trying to find GSM towers or anything.
[EVO 4G General] thedoubbledonkey:
So true

This trick worked for me. Going on 8 hours with 40% left, normal usage.

[Hero CDMA General] wmblalock:
Alright, so I updated my phone with the official 2.1 android update from sprint, then rooted it. I hate 2.1 and my phone runs like complete crap. I even tried to re-flash it after doing a hard reset, that didn't help. I am very new to android phones, but learn fast. I downloaded the initial release ruu from sprint which has android 1.5 but can't simply run that to flash back to a 1.5 rom because it gives some type of error about not being able to update the boot loader or something. I gather that I need to get the original 1.5 rom in .zip form somewhere and then flash that rom using the menu at the phones boot up to get back to a 1.5 rom. Can someone tell me what I need to download, and the steps to do so? Also is there any 1.5 roms that are nearly identical to sprints stock rom but that have tethering enabled? Thanks guys!!

You can not go back to 1.5 after running the 2.1 RUU. The hboot in 2.1 has a higher version and you can not downgrade below the version currently on your phone. The only thing to do is install a 1.5 ROM..

Just look in the Wiki, there are several 1.5 ROMs.
