You don't change it and change it back. You press menu> change radio band.

Then it force closes.
[Hero CDMA General] watzone69:
One hour ago my TWS was 50%. I did the steps given in the OP and my TWS has dropped to 1% in that hour. I did NOT do the airplane mode toggle.

EDIT: This works. My battery has not dropped AT ALL in the past hour.
[Hero CDMA General] crash447:
I know/knew that I didn't change it and change it back. I was trying to point out that I was not getting a force close. That is also why I was thankful for the diagram since I refused to read the instructions two times. It was my fault and apparently I needed a picture to realize my mistake.:)
[Hero CDMA General] abcdfv:
Are you on DamageControl? What happens when you tap the "Change radio band" button in the menu? This is the first I'e ever heard of someone not getting a Force Close.
[Hero CDMA General] Sporkman:
i was at 51% TWS now im at 42 % TWS and dropping its been about 2 hours
[Hero CDMA General] crash447:
I don't know if I am just being confusing (probably the case :) ) or you are just not following what I am saying. I was doing the process wrong. I was not hitting the menu button. That is why I am so thankful someone posted the picture. I was not following the directions correct. Once I did it correct and hit the menu button it worked. I was just being dumb. Thanks so much for the help.
[Hero CDMA General] abcdfv:
Sorry, thought you were being sarcastic.
[Hero CDMA General] Wasney:
I did this about a hour and a half ago. it was at exactly 50%. Now it isn't even listed.

DarchLegend ROM

I'm on DarchLegend 4.1 and didn't get a FC when I selected the radio band. It popped up a menu giving several different countries that I could set my GSM radio to. I would tell me that "Set [whatever] band unsuccessful" if i tried any of them, but no FC.

Anyways, i set the radionetwork to GSM/CMDA auto(PRL), left the app, and went back and set it to CDMA auto(PRL), and it seems to stick. I was at 37% and I've dropped to 30% in the past 10 minutes.

Also, at least with the Legend ROM, whatever setting I put the network type on (GSM, GSM/CDMA, whatever), it seems to stick after a reboot. Does it do the same with any other ROMS, or is the "visual trickery" only show CDMA auto(PRL)?
[Hero CDMA General] beyondinferno:
abcdfv, thanks for posting this walkthrough. I figured out the procedure originally with the exception of the test menu (don't remember who posted that part), but I was having trouble writing out clear instructions.

Well done sir. Well done.

PS. You might add in big bold print in the first post this works with 2.1 ONLY.
[Hero CDMA General] lalo45:
Quick question. What if i shut my mobile network off when im not using it, when i turn it back on would these settinggs stick, or do i have to repeat the process.
[Hero CDMA General] abcdfv:
I haven't tested this.
[Hero CDMA General] mercuryhayes:
whats the difference between cdma auto and cdma only??????????
[Hero CDMA General] nebenezer:
+1, why not just choose CDMA only?

I followed your instructions, my tws went from over 50 to 24 back up to 46, I checked wagain and it was set back to GSM auto... I hadn't rebooted or turned data off.

I'm going to try CDMA only and just see what happens.

Thanks
[Hero CDMA General] abcdfv:
CDMA only prevents it from reading the p(referred) r(oaming) l(list).

So no roaming.
[Hero CDMA General] nebenezer:
Thanks

[Hero CDMA General] mercuryhayes:
ive been doing cdma only and dont have issues and when i reboot, i once in a blue moon get the 50% thing...imma keep it the cdma only way seems to do well for me
[Hero CDMA General] dmc971989:
so this may reduce time without signal and all, but im not sure about helping the speed of your connection...

my sig is speedtest.net via Mobile Network Sharing (Darchlegend v4.22) before doing the CDMA (auto Prl) fix

this:

Is after the fix...

something is fishy here...
[Hero CDMA General] abcdfv:
Never said it'd make it faster, just save battery.
[Hero CDMA General] dmc971989:
OK, but on the previous Darch release (4.1) i didnt have any kind of batt life increase... batt life with that rom was aweful for me actually....

ill give it another shot with the newest darch release and report back...
[Hero CDMA General] abcdfv:
Like I said, Damagecontrol v 1.0. I make no claims as to how this effects other roms.
[Hero CDMA General] nebenezer:
I put it back on cdma auto before hitting the sack, I'm @ 6% tws and lost 9% battery in about 6 hours.
[Hero CDMA General] Sporkman:
im at 0% TWS woot !
[Hero CDMA General] teedo757:
Well as soon as I switched to cdma my Battery Cell standby % has been dropping slowly all day (7 hours) and I am down to 47% and my TWS is now 30%. I am curious to see how long my battery will last now! Thanks for the fix.

P.S. is 4636 and acronym for anything? Ex. 33284 is for debug
[Hero CDMA General] abcdfv:
I couldn't tell you.
[Hero CDMA General] Kcarpenter:
Plug it in to USB/Charger and unplug it and it will go down instantly :D

EDIT:

Anyone think we can get this scripted at startup??????
[Hero CDMA General] abcdfv:
I've been thinking about this, but I don't know nearly enough about phones to implement everything.
[Hero CDMA General] thedudejdog:
4636 = data

oops.. thats ##3282#

sorry my brain is mush
[Hero CDMA General] toastcfh:
heh sweet. good find and thanx to u and whoever figured it out that u dont remember :p
[Hero CDMA General] david279:
ok this works great now need a start up script for it. Also this made my network type appear as "evdo rev. a" for the first time since i got it. Im happy with battery life too.
[Hero CDMA General] CHANG3D:
How did you do that? Mine still says rev. 0.

But switching to cdma does save battery life! I went from 27% overnight to 7% overnight. That's ridiculous!

Thank you!
[Hero CDMA General] danaff37:
I went to check this, and under my battery info it did not show time without siganl at all.. just a time on. So I went to try this anyways just to see where my setting was at. And here is what I noticed... when it force closes and restarts, you can see your signal strength bars go to zero with an x, then come back and then it says gsm (auto)... I changed it to cdma (auto) then. But the signal bars made me wonder... with the force close, are you sure you are not just restarting the radio software, which defaults to gsm (and it was on cdma before) so you change it, and basically what you are doing is just a longer process of the airplane mode trick (basically just restarting the radio)?

I am running DC v1.0 with JIT by the way if it makes a difference (doubt it)
[Hero CDMA General] TechniShawn:
awesome! Mine says rev. A now too!
[Hero CDMA General] mjodotcom:
I am running Damage Control 2.0r2 and noticed that when I type in the 4636 code nothing happens...the code just disappears and the phone sits there. I don't really touch anything on the phone but it never goes to the testing screen. Thoughts?
[Hero CDMA General] ElAguila:
The code should be *#*#4636#*#* Are you putting in the pounds and asterisks.
[Hero CDMA General] monkeyzero:
Oh wow, worked like a champ for me on Damagecontrol 2.0

[Hero CDMA General] aauussttiinn88:
are you tryin to send a text that is bigger than 160 chars>?
[Hero CDMA General] orris:
I'm trying to send a picture with the stock message app. Which worked fine before I tried this. Also, when I go back into Phone Info it says that it's back to GSM auto (PRL). I change it and then it goes back when I exit. So far I've tried changing it again and again. Trying CDMA only and CDMA auto as well as CDMA/GSM auto. I've tried rebooting the phone. Nothing fixes it.

EDIT: Tried it again. Changed it to CDMA auto and immediately exited and tried to send a picture. Received an error "Generic Network Failure". I've gotten that and SMS Failure. BAH!
[Hero CDMA General] Tikerz:
If I flashed back to the stock radio, I wouldn't have to do this anymore right?
[Hero CDMA General] abcdfv:
Try it, let us know.

Just trying to give a little back to a community that's given me so much already.
[Hero CDMA General] Joecrack305:
doesnt work at all for me, my awake time is at 100% is there an option after you set it to cdma to save it? because when i went back in without resetting it was back on gsm.
[Hero CDMA General] superlinkx:
Has anyone else noticed that if you enable this, then go back it already is switched back to GSM? I'm going to test it again, but it looks like it may not fix it afterall.
[Hero CDMA General] monkeyzero:
It's because, as noted in one of the original posts, it's a visual glitch. I switched mine from the GSM Auto to the CDMA Auto and have seen a drastic increase in the battery life as well as seeing the TWS go to zero. If I go in to look at the setting right now it says GSM Auto but it's actually on the correct setting of CDMA Auto. Again, the reason is because of the visual glitch. If the TWS goes down and the battery life goes up then it is working properly regardless of what the setting shows. Hence the nature of VISUAL glitch.

However, as said, if you reboot your phone, it reverts back to the GSM Auto and you need to do the reset again.

Does that make more sense? And honestly I'm not trying to be a know it all or condecending, just explaining why it seems that the switch is not sticking.
[Hero CDMA General] ElAguila:
I have noticed a couple of other things and I would interested in hearing from others about their battery life. After doing this fix the battery lasts longer but still drains much quicker than the older roms. I checked and the battery use is showing bluetooth to be the same % as cell. Bluetooth file sharing is disabled. I am wondering if this contributes to the battery drain as well.
[Hero CDMA General] Joecrack305:
how do you get to time without signal i saw it before can't find it now.

im on damaged trev this **** is killing me i've done this a million times, and im still at 100% awake.

edit time without signal 0% but my awake time is still 100%
[Hero CDMA General] :
I'm trying to find out where these changes are saved any ideas ?

Also while I had logcat going I noticed my IMSI 'appears' to change when I switch the PRL triggering account manager to wipe my google password. I'm beginning to wonder if this problem and the always having to login are related.
[Hero CDMA General] superlinkx:
Yeah thanks for the clarification. My phone started to really show up with the 50% thing today, so I now know it is a visual glitch. This is really annoying. I hope someone finds a permanent fix soon.
[Hero CDMA General] masterninja:
I had the same thing happen, so I took this...http://damageless.kingspond.com/signed-mms-fix.zip, loaded from recovery, and it is working! However, when I reboot I notice my TWOS is back up to 50%. BUT, if I let it go for a while, it goes back down. I've been in the single digits. So, as far as I can tell you, this worked for me...hope it does for you. Before you go any further, what ROM are you running? I took this from Damage's v1. If anyone has any thoughts, please let ORRIS know. I wouldn't want anything bad to happen. Thanks!
[Hero CDMA General] orris:
First, thanks for being nice enough to try to help me out. I'll try that and yes, I'm running v1 DC. Thanks, man.
[Hero CDMA General] Jedis:
Is this needed with DamageControl 2.05?
[Hero CDMA General] abcdfv:
I'm still testing with 2.05.

So far, the results are encouraging.
[Hero CDMA General] mountaindont:
i have been testing for a week now, and this fix simply does not work....(for me?) my up and awake time are still matching, though admitadly my cell standby time is down 10%.

are there any other battery fixes?
[Hero CDMA General] SamXp:
Same here. Just flashed DC2.07.2 and my Cell Standby is 35-55% even after setting CDMA auto (PRL). Can't get 4-6 hours out of the battery!

DC2.05 was fine, I might go back to it.
[Hero CDMA General] Danokan:
When I do this.. i LOSE my network connection.

Cannot do anything via internet.

EDIT: Never mind. It came up now. thanks.
[Hero CDMA General] abcdfv:
This is a Time Without Signal fix, that fixes battery issues caused by the phone searching for a GSM signal. Has nothing to do with awake time, as far as I can tell.
[Hero CDMA General] ROB281:
Settings> About Phone> Battery> Battery Use> Cell Standby.

I don't have this on my hero

I go to settings> about phone> & under there all I see is

system updates

status

legal info

sys. tutorial

then the model & build #'s

under status I get batt status, and level, but nothing to show use

it does show my network type to be CDMA - EvDo rev. A though

also shows my up time as 24:24:seconds ticking, with an awake time of 7:54 (32%)

do I need to add an app to see battery use?
[Hero CDMA General] dec3ption:
You have to be on a 2.1 ROM. Time without signal doesn't show up in 1.5 ROMs.
[Hero CDMA General] ROB281:
thanks for the info

is this still something I could try?
[Hero CDMA General] dec3ption:
Someone correct me if I'm wrong, but you shouldn't have this issue on 1.5 ROMs
[Hero CDMA General] abcdfv:
Not as far as I can tell.
[Hero CDMA General] ROB281:
even better, thanks guys
[Hero CDMA General] stricklerjosh:
After changing mine I am still at around 45%...any ideas?
[Hero CDMA General] JusticeAA:
After I switch it to CDMA Auto then go home, I repeated the process and it is right back on GSM (no reboot, just home then back to testing).

I am not sure this is actually changing anything. Running Fresh 2.0d
[Hero CDMA General] abcdfv:
Anyone else on 2.0d having the same issue?
[Hero CDMA General] Penny:
This happened to me the first time I did it....after I changed it the first time I got out of it by tapping the back button. Then when I went back in to see if it had saved it was back to gsm. Then I changed it again and went out of it by hitting the home button instead and it saved correctly.
[Hero CDMA General] mich0020:
When I do this fix I lose my EVDO connection altogether....no internet at all...am I doing something wrong. (Fresh2.0d)

How are you supposed to exit out once you've done the fix? Back button or home?
[Hero CDMA General] LoneStarPhD:
I have Fresh 2.1.2 and it shuts off my EVDO. Not sure what I am doing wrong.
[Hero CDMA General] JusticeAA:
If I understand correctly the GSM issue has been corrected in Fresh 2.1.2 so you can just restart your phone to get back the default settings and your evdo.
[Hero CDMA General] ryatziv:
Same here.
[Hero CDMA General] KitsapAndroid:
Well, my TWS says 96% so I figure I'll give it a try. I think it's cause I have been at work all day and do not get the best coverage where I work, but maybe this has something to do with it. Time to find out.
[Hero CDMA General] PhoneStupid:
I am new to this whole site and updating phones in general. I went into the battery use setting and it shows that my tws is 0% but my idle is 49% and the cell standby is 46%. I just did what the OP said and awaiting results. I will update when the numbers change.

Thanks,

Luke
[Hero CDMA General] nebenezer:
If your TWS is already 0 then the instructions in the first post aren't going to change anything for you.

The idle and standby being at 49 and 46% is normal and no indication of an issue that can/should be resolved.

The "battery use" list does not reflect HOW MUCH of the batery is being used but rather itemizes whatever amount of juice IS being used.

The items in the "Battery Use" list will/should always add up to 100%.
[Hero CDMA General] spanglmd:
edit: nevermind.
[Hero CDMA General] LexusBrian400:
You guys know there is an App called "Network" that does all of this? I didnt read all 10 pages, so maybe you do. Just thought I'd mention it for those that dont.
[Hero CDMA General] SimPup:
Can't get it to stick. Just keeps going back to gsm no matter which way I do it home or back. Tried it bout 20 times already
[Hero CDMA General] wookietv:
would anyone know why or has anyone else experienced this... in my battery use listing, i see:

Camera 96%

Cell Standby 2%

Phone Idle 2%

Camera 96%?? 34 minutes since unplugged... haven't used the camera at all since then.

so will this stay in the cdma prl mode or will i have to go in and change the setting every time i reboot my phone?
[Hero CDMA General] pwrmedia:
It doesn't hurt to adjust the setting after every reboot, even though you're probably going to get different answers on this. Some swear that on certain ROMs the setting will stick, but depending on other things you mave have altered after the initial setting, there's no guarantee.

dont do it on Evo 4g

Don't try this on Evo. why i say this because i have. Just to see if my battery would go longer all it did that i noticed was when i went to change the wallpaper it didn't change then i powered off phone tried powering it back on and it didn't power on. I had to remove the battery for at least 10 seconds put it back in then it powered on little scared there for a second. You may think why try this when this is clearly for the hero cdma instructions well i followed this link http://www.mobilecrunch.com/2010/06/03/tips-and-tricks-to-extending-the-htc-evo-4g-and-incredibles-battery-life-and-what-this-says-about-android/ . well guess i know now it doesnt work on evo.

My cell standby is currently at 48% battery in my settings --> about --> battery area.

Should I try this network app, or this hack to see what happens? Is this a normal % for everyone who hasnt applied this MOD?

Crazy...
[Hero CDMA General] scriptx:
Wouldn't this just be a software oversight, seeing as though there is no SIM card on this phone, and it shouldn't be able to associate with a GSM network?

My uptime was just 1 hr, and my time without signal was 26%. After setting to CDMA ONLY (prl), it's already dropping. Everything works fine.

I've installed the Network app which makes accessing this form easier.

If this is really the cause of the battery drain, then HTC/Google needs to issue a fix right away. Battery life is a big seller, especially when comparing to the iPhone and other competitors!

turned phone off over night & now phone not sleeping????

Hi Everyone

I m running Aolysuis 2.1

I noticed yesterday that my phone was at 100% wake time :-( I followed the steps and first let me say that when I went to "menu - settings - about phone - battery" there was no information about signal just a display showing the battery level and my up time and sleep time (which were identical) I continued with the steps to access the service/testing menu. The radio was "gsm (prl)", I clicked on "change radio" and got the "force message" I then changed the radio to "cdma auto (prl)" or what ever it says in the write up. After I exited out there was no change to up/awake time where still identical even after turning the screen off for a bet to test. I also wasn't able to connect to the internet or the marketplace. I did a reboot and was able to connect to the marketplace and internet and when I turned the screen off the wake time and up time were different.

I turned my phone off over night as I usually do every night. When I turned it on this morning I noticed that even though I turn the screen off the wake time and up time are now always the same again :-(. I went back into the test/service menu and it shows that the radio setting is what I changed it too "cdma auto (prl).

Can anyone help?
[Hero CDMA General] karasuhebi:
I have the official Sprint/HTC 2.1 ROM (rooted through UnrEVOked) and I don't see the TWS bar on the "Battery Usage" screen. I still went ahead and did the fix and everything went as described (including the Force Close). Should I notice some battery life increase or was this issue fixed in the stock 2.1 ROM?

Thanks,

-karasuhebi
[Hero CDMA General] ufkinloveit:
I think it depends. I had the stock rom with the OTA update and when i checked the fix it was already set to cdma auto, however i was still experiencing battery problems. I did a hard reset (settings >> privacy>>factory data reset) which i saw recommended on another forum to do after this fix. I did it and now the TWS actually went to 0% before i had 8%-15%.

The problem is it erases all apps and settings but i think its worth it, if it will allow you more juice out of your phone. I am able now to go online, have wifi on, bluetooth and some light phone talk, and im at 77% after disconnecting since about 10AM. I'm very happy with the evo now all things seem to be working fine, i had the hardware version 2.
[Hero CDMA General] ufkinloveit:
Forgot to mention i'm also running unrevoked, the overclock widget with screen off set at 245mhz and Advanced task killer, with autokill at crazy and frequency set at when screen turns off.
[Hero CDMA General] abcdfv:
You did it wrong.
[Hero CDMA General] alltimesaresoon:
phew

ok, let me know if this helps YOU. i've read all the battery posts. nothing has helped me very much at all. i thought turning off the synch frequency helped, but ugh, my batter would still drain in about 4 hrs. knew SOMETHING was wrong.

well. i have about half strength signal at my home from sprint. and i have NO signal from sprint at work. and i spend a lot of time at work.

well, turning off the gsm to cdma or whatever, i could NOT get it to stick and stay that way and would not improve my idle time usage.

SO i added this widget "EASY SWITCH" and now all i do is turn off the cell phone radio antenna widget when i'm at work. Voila. all of a sudden the slope of my battery drain went to about 1/4 or less of the drop off that it had previously.

This works for me because:

1. I was used to poor/no signal reception at work already on my rant.

2. I have wireless connection at work, so i can get all emails and everything essential i need. and my wife can email me instead of text and phone call. I don't really NEED voicemails or phone calls on my personal cell during work.

3. I have a company cellphone nextel (mexican #), that people can call me on if it's an absolute emergency.

This situation may not help you as you may want a cell phone during the day to be a cell phone. I don't. I need it for all the other goodies, and especially for my email, internet access, etc. And i can always use skype or something to call over the internet, or turn on the antenna and go stand on my tippie toes in the corner of the parking lot to try to get sprint reception.

anyhoo. if you find that you can't execute this cdma thingy and get it to work. just do what i did. turn off the bloody cellphone radio. it's an absolute battery SUCKER if you don't have strong signal.

I leave work, and on my drive home, signal is fine, (only 40 min anyway) and flip on the antenna radio again.

BEEEAAAUUUTTTTIFFFULLL!
