Which ones should we be using for the Tbolt?
So far from what i noticed...
LTE Only (when iuse this i dont get phone calls or cant make calls)
Global+LTE (seems to be the 4g Only mode to me? i canmake calls)
GSM/WCDMA/LTE (not for us? )
CDMA+LTE/EvDO auto (This is for full 1x,3g,4g)
Global (????)
CDMA w/o EvDO- (Guessing just plain 1x?)
CDMA/EvDo Auto (3g/2g? )
i assume we dont use the ones below:
GSM/WCDMA Only
GSM Only
GSM/WCDMA Preffered
I did a quick search but didnt find a answer..
Still Googl'in....
You want to use CDMA+LTE/EvDO auto
I find that i have to set it to CDMA / EvDO and wait for a 1x or 3g connection then switch to the CDMA+LTE?EvDO mode to actually get 4g.
I was hoping i can set it to 4g only again like with The sense roms to save on battery?
No sir

LTE+Global seems to work too.
LTE alone doesnt let me make phone calls.
My question now is.. what is "Global"?
I'd really like to have this answered as well.. I just flashed Cyanogenmod 7.1.1 and if I use LTE only (like I used on Sense roms) I keep getting sms not delivered errors (haven't tried making a call... but from this thread I'm guessing it won't work)
is Global + LTE our "LTE only" on this rom?
I like using LTE only because the 3g/4g auto choices like to chomp my battery.
(And I second the question: What is "Global"?)
If you're wise, you will avoid messing with those and just use the toggle button on the power widget.

I understand where you're coming from, however, the "4g" option on those types of toggles usually means 4g/3g auto, rather than 4g only. The reason we are looking for the answer for this is we want the 4g only option that will still get voice reception. I like to use the 4g only option to conserve battery (and it makes a huge difference to me, I'm at work for 10.5+ hours a day, and if I have it on 4g/3g auto, it dies pretty quickly. If I have it on 4g only, I can go home with up to 60% of my battery left!)

If you do "4g only" it's still going to fall back to 1x if LTE is not available. I don't quite see the advantage of it really.
Settings to Try
Cyanogen is built for multiple phones so a lot of these options apply to GSM phones not our CDMA phone, our phones are at their base a CDMA phone with an LTE chip added on for only data access.
so you don't use options that don't reference CDMA.
Cynogenmod doesn't have a CDMA/LTE only mode.
Don't Use
LTE Only - don't use this it turns off the cdma radios, ie no phone calls or texts
GSM/WCDMA/LTE - not for us, this is for GSM or World phones not ours
Global+LTE - (This is for full 1x,3g,4g), but I wouldn't use it, this for for verizon world phones that have CDMA and GSM radios, my guess is that a lot of unnecessary GSM code is running with this option
Global - this for for verizon world phones that have CDMA and GSM radios, my guess is that a lot of unnecessary GSM code is running with this option
Valid options
CDMA+LTE/EvDO auto (This is for full 1x,3g,4g) - this is what the vast majority should use most of the time.
CDMA w/o EvDO- (Guessing just plain 1x?) yes it's just plain 1x, if you really need to save battery life for calls this will save it, but your data will be basically unusable.
CDMA/EvDo Auto - If your in a 3G only area for a long time this can save you some battery life, because it won't constantly be looking for a lte signal that isn't their.

Hi all.
I have had my N1 for a little over a week now, and the battery life i guess is normal for a pda with this power etc, but i read over on modaco that by changing over the settings from CDMA preferred to CDMA only, actually increased the battery life loads! So I tested this and indeed it does nearly double my battery life..
I have also now read from an add for the new HD2 that the battery life is again increased by swithching over to GSM only! Look at the battery details quoted for the HD2 below.
Talk Time –
Up to 320 minutes for WCDMA
Up to 380 minutes for GSM
Standby Time –
Up to 390 hours for WCDMA
Up to 490 hours for GSM
I am now testing GSM only, and guess that the battery life is going to increase yet again, awesome..
this looks promising but T-Mobile has lots of 3G dead spots scattered around even a major city like NYC, meaning if I would set the phone to WCDMA only and put it in my pocket, I would not receive any calls or data when not in a 3G area.

u do know that with WCDMA you will get far better speeds than just plain old gsm right?
Setting it to WCDMA only will actually drain your battery faster if you are in an area with poor 3G. So only use it when you have optimal 3G conditions.

Faster yes. But noway worth the hassle of toggling it on or off. Unless you don't like to charge your phone each night then its not a prob. I use 3G/wifi,music,games and my battery easily survives a day or two.

Thanks for that Amon_RA, and a personel thanks for for RA-nexus-v1.5.3
I guess my phone usage is split 50/50, i.e 50% at work with a max 3G signal, and 50% at home with a weak 3G signal. I definately saw a massive increase in my battery life when on WCDMA only, so changing to GSM should benefit me even more. I live in the UK and am on the Orange network, overall the 3G coverage is not to bad.
I will report back after a couple of days testing.
Good news for me: there is basically no 3G coverage here so guess I'll be GSM all the time. Getting my N1 this afternoon.
Is it just me or am I not seeing a 200% increase? 20% maybe.
how do i actually choose which band to use? been trying and didnt see any options.
in your dialer dial *#*#4636#*#* then go to phone information > set it to WCDMA only (3G only). Default is WCDMA preferred.
thanks! guessed i learned something new today
Hi again everyone..
Well one day into testing GSM only, what a difference in the battery life..
This is my default setting definately when on holiday to save on power, and when I am not using data roaming. But the speed difference is bummer, i.e GSM only gives me GPRS slow-ish speed, and not fast speeds that 3G gives you, if you are in a 3G area that is.
I have now found an easier way to switch bands, well at least between CDMA preferred and GSM only mode's, and you don't have to switch off your N1 or even put it into flight mode anymore.
1-Swap your band to GSM only mode via phone keypad.
2-When you need 3G speed if available just go to settings/wireless & network settings/mobile network settings, and untick box to use only 2G networks.This re activates the CDMA preffered mode.
3-When you want to go back to GSM only mode, re tick 2G box as detailed in 2 above.
If you use GSM, and by extension GPRS, most if not all of your calls will go to voicemail. 2G only means your phone can do either voice OR data at a particular time - eg If you're browsing or reading messages or syncing you wont get calls. Conversely if you're talking on the phone you can't browse the web. This is why 3g is so much better - you can do both simultaneously.
You may already be aware of this but I thought I'd mention it just in case you weren't.

actually when android receives or makes a call on EDGE / GPRS it automatically turns off data to allow the call to get through.
This is a must solution if you are on AT&T, with the phone only being gsm capable for me it has increased my battery life by I say 20-30% and going into settings also and switching to only use 2g networks works amazing.
I wonder if there will ever be an AT&T nexus AT&T thats what all my family use..

AT&T doesn't support this (or didn't a year ago when I last looked into it) for incoming calls, so be careful if you're using AT&T (of course, if you're on AT&T there's no other option).
T-Mobile supports this, so it'll work fine.

thanks alot for this code it helped
I dont know why everyone is treating this GSM vs 3G battery life stuff as if its something new..
Those who remember, the iPhone 3G suffered from the very same issue...
wooo hooo!
Poll in..
Finished testing..
GSM only mode is a definate winner as far as battery life goes, but the down side side is the slow data speed side, and the fact that you can't recieve calls when say surfing, or when data is being downloaded in back ground, it just goes to voice mail... Try it.. change to GSM mode, phone yourself via a land line while surfing etc and see your calls go to voice mail.
The easy switching via the 2G mode does help, and you can swap as and when required, but as alot of my current N1 apps connect to the web for updates etc (beautiful widgets for weather updates, e-mail checking etc) I will stick to CDMA only mode for now, and just use GSM mode when I go on me hols abroad when I don't use data at all.

Receiving calls during 2D data transfer is a feature that needs to be supported by your mobile network. Your mobile operator probably needs to implement a Gs interface and change the Network Operation Mode. That way your phone can be paged during 2G data transfer and you'll be able to receive the call.
I found something a couple days ago that helps the standby battery life on all Android devices, and figured I'd share for those of you who don't know.
I've tested this on a Captivate and an Evo 3D GSM, and both have noticed significant improvement. Normally if I leave my phone unplugged at night, when I wake up I'd be almost dead. Now, I went to sleep at around 60% Battery, woke up and it was only 40%. Not too shabby.
Anyway, what needs to be done:
1. in the dialer, punch in *#*#4636#*#* (You don't have to press send, it will automatically bring you to the next menu)
2. from here, go to "phone information"
3. There is a dropdown menu that says "Set preferred network type". By default this is set to GSM/CDMA auto(PRL), change it to the specific network type you need. I'm with Rogers, so I went WCDMA only. If you have the Sprint version, you'd go CDMA only.
4. Now, on the main screen again, press Menu>Select Radio Band
5. Select the appropriate band for your location. In Canada, USA is the same band, so I went with this. The options are Automatic, Euro, USA, Japan, AUS, AUS2
6. Exit this screen and use your phone as you usually do now. This won't affect battey usage while actually using it for calls, browsing, etc. But in standby mode it does increase your battery life.
Hope that can help at least a couple people.
How interesting. I remember this setting for the EVO 4G. But, I only drop a few % in standby mode and that's overnight..
I just took a peek first to see. I have two questions.
(1) What's the difference between "CDMA only" and "CDMA auto (PRL)"? Mine was set to the latter.
(2) I pressed menu on both the main screen and under "Phone information". My phone has no selection for "Radio Band".

1. Not sure. I'd assume cdma only will only care about cdma vs other types of signal. The 3d only has thecdma radio so cdma only would be the way to go for you, I suppose this option is here for dual cdma/hspa phones. There must be some background processes running when you have it in auto mode.
2. No idea here. Perhaps this isn't an option on cdma phones? Doesn't make much sense though. I tested this on my 3d,, captivate and a nexus a, all were hspa phones, but it was there for all of then

Odd..
Must be something unique to GSM phones only. Sorry guys. However, I'd imagine setting it to CDMA only would help a bit as well.
Did this on Sprint Evo3D yesterday, there is no option for the radio. Also just going CDMA only still have my standby drain at 39%..
it should be noted OP that this will only work for GSM 3d because CDMA 3d (Sprint) doesnt allow radio band changes since their is no other frequency to receive service from a different carrier. The only two US CDMA providers Verizon and Sprint use the exact same frequency for 3G and 1X which is why CDMA phones are not world phones. Good info though too bad it doesn't apply for the majority of 3d owners
I dialed ##3282# entered msl code and was able to see the setting freeza mentioned.

Hey XDA,
I'm running Android Revolution HD 3.0.0 with S-OFF and SuperCID. I am using Mobilicity as my carrier. When I first installed Revolution HD, I did not back up my APN's (it didn't say to do that in guide). After booting up for the first time, I was unable to use Mobile Network until I posted here asking why it wouldn't work, and I was told to put my APN's in.
After putting the APN in for Mobilicity, Mobile Network began to work. Here's the problem though - my phone is trying to use 4G on a network that hardly supports 3.5G. Prior to installing Revolution HD, my phone would switch between using 3G and HSDPA to manage battery consumption better. Now when I turn Mobile Network on, it consistently stays on 4G, burning up more power than before.
I can tell you that 4G is useless on Mobilicity because my data speeds are about 2Mbps download (Speedtest.net App).
Could someone provide me with APN to disable 4G from turning on, or if a different APN is not the solution, provide me with an alternative method.
Thank you so much XDA, you've been great,
Robert
Actually ARHD is based on T-Mobile's ICS, which actually switches between 3G and H (on T-Mobile they label it 4G but it's actually H), as I was saying, it actually switches but T-Mobile had HTC modify the system files to show 4G whether the phone is on 3G or H, it just shows 4G all the time, so calm down.
Next point is, your phone switching between 3G and 4G, it's not a form of saving power, it's just your phone showing what coverage it has, therefore your phone is constantly switching between the two, so your power consumption isn't to blame on your coverage if you're in basically the same areas as you were before flashing and your coverage remains similar, but most likely on some programs you have running in the background or well, you just find the phone more usable with ARHD and you're just glued to it more than you used to be. APN settings have nothing to do with 3G or 4G, most if not all carriers use a general apn, it's upto the devices capabilities to determine what data type would connect and what data coverage they provide.
Alternative to reduce power us would be to switch your phone to GSM (2G) coverage only, which would be slow, compared to your current 3G.
Okay thank you for your reply, but I will dispute the fact that ARHD does not use more power than Stock (or just the same).
Using the built in battery monitor, it shows me how fast my battery dies based on the type of usage (it has that graph thing, i'm pretty sure most android phone have it). The phone remains pretty much stagnant with battery usage when its screen is off, but when I turn the screen on, BAM, the battery begins falling vertically. If I get a chance I will upload a picture of my battery usage.
It is literally the same as stock, I honestly get no better battery life with ARHD than before. Although I am not saying that ARHD does not have its advantages such as running the OS much smoother and ICS being awesome.
Robert
Check if your brightness level is too high, I use auto brightness, ARHD is basically stock, just tweaked and a few additions to make it better and smoother.
You can also check the Amaze Bible thread for tips and tricks on improving battery life, it's a general list, so should be able to help, at least a bit.
Anyone have any luck finding a toggle or switch to disable 4g? Running eclipse tw based. My office is on the borderline between three and four G. Kills my battery.

I have an app I got from here called Phone info. Don't think it's on the Play store though. It's similar to what LTE switch was on my Rezound. It gives you the abillty to select the radio. However, I've noticed this phone is not "happy" when LTE is switched off. Many times when I know there is a 3g signal, and I force into EVDO it doesn't always take. And other times when it's stuck on 3g and I KNOW there is LTE and I force it into LTE only mode, it says not signal until I put it back into LTE/CDMA and then it picks up LTE. What I miss was the option the Rezound had where it was LTE/1x so it was LTE only but still had voice and texts.
see that:
http://forum.xda-developers.com/showpost.php?p=44962652&postcount=37
This app works fine for me. Its a couple of more keytaps but does the job like lte toggle app.
Of course until VZW gets their act together and launch band 4 across the country to fill in the gaps, this is the best to get around the constant switching/searching for baseband.
Would you use a 3G only option if it was available on the G3?
I spoke to a Verizon Regional Exec today about the G3 and other Verizon phones that no longer have the option to run on CDMA only. The rep has an iPhone and regularly sets it to 3G only, especially when he let's his kids use the phone. He could not give me a reason why the G3 and other phones no longer has the ability to go to 3G only. He said he would look into this and see if it could be delivered in a future update.
Honestly I rather not have data at all then be stuck on 3G, just my opinion
I would like that option. There are areas where I play Ingress, for example, where the 3g Verizon signal is strong and uncluttered so its a much better option than LTE, which is either weak and eats battery trying over and over to reconnect, or is good but WAY oversold so there is no way to get good speeds on my unlimited data plan, much of the time.
One of the tricks we used to use on the VGNexus phones was select 3g only and save much battery life. 3g can sometimes be faster than 4g and it saves power by not running the rg radio.

I can do this using com.lge.hiddenmenu. it has an intent that if launched will allow you to pick your desired frequency/bandmode. it includes lte only, cdma only, evdo only, cdma/evdo, and lte/cdmA/evdo as well as global.
i often have poor band 13 lte coverage and so it saves a lot of battery. sometimes it is nice to block 1x to improve speeds and force 3g if the signal is producing more speed then 1x. just my 2 cents,,,and if you get creative you can create a shell script to "su" then run the intent and then exit. place a shortcut on the homescreen and profit.
im reflashing my softbrick now or i would put the exact intent needed, maybe tomorrow if i remember but its network selection, network mode, something like that and way towards the bottom (last third) of the intents i viewed within hiddenmenu,apk
Please conform that the coma,option is available on works on the vs985

The GNex was one of the last phones to be affected by that. Since Qualcomm took over Android, their integrated LTE radios use no more power than 3G radios.

Completely agree, even a very weak LTE always works better for me, even over a full 3G signal at times.

Basically. I think a full 3G signal is a little faster a very weak LTE signal, but at this point anywhere there's full 3G there's LTE.
Just download a massive amount of data and the carriers will throttle you down to 3G or lower, with occasional 4G use. As for some people saying that 3G is never faster, it depends on the carrier. Verizon throttles all 3G usage in an effort to convince 3G users to upgrade to 4G.
