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.

Hey, I have an USA T-Mobile Vibrant.
It is rooted and running the Vibrant edition of Darky's 9.3 Final ROM.
I am also using the latest overstock kernal and the honeycomb 2.0 theme from the I9000 forums.
Enough background info. This isn't really a problem as much as my curiosity.
My phone almost constantly is switching back and forth between 3G (UMTS) and H (HSDPA) on my data connection.
It doesn't seem to affect battery life or service too much (though H might be faster), so I'm not worried; but does anyone know what the deal is with this?
Thanks ahead of time!!!
Sent from my Vibrant using XDA App
Mine has been doing this lately as well. It's only been happening since I installed my current ROM (Trigger 2.7).
Noticed this just now as well...might have something to do with the mods to show H or 3G.
I wonder if it has anything to do with signal strength. I know that shouldn't make a difference but I can't think of any other reason.

I would agree, but I went to my settings/ phone info/ signal page and the reason it was changing was because it was physically switching between UMTS and HSDPA.
Why? I have no idea.
I do live in a T-Mobile 4G enabled area, though I am not on their so called "4G plan".
I did notice that it did not have this switching problem on Bionix Frost-u2.
So, if anyone has some insight, please help us all understand

I was just watching my signal strength change and it doesn't seemed tied to the change from 3G to H.
For example, it would be around 67dBm and be on UMTS. Raise to up to around 75dBm and be on UMTS. Then it would switch to HSDPA and still be at 75dBm or sometimes lower down to 69-72dBm and still be on HSDPA.
So with that type of cross-over stats, I would be skeptical of that solution.
HSDPA is a temporary data link. If it was on continously the phone would have very poor battery life.
When network server has a data packet for your phone it 'pages' up your HSDPA capability. Your phone can also request HSPA to initiate a data transmission.
The HSPA paging process is similar to receiving and initiating a voice call.
If no more packets have qued at their server or received from your phone after some period of time it will revert to normal 3G battery saver cycling. It has to be re-paged up to reinitiate HSPA data link. The wake up HSPA function does add some initial delay.
So is there a way to force it to stay on HSPA while tethered, for example? (Or always)
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
Sent from my ThunderBolt using XDA Premium App
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, I looked for this in all motorola forums but I couldn't find any real solution.
It seems the latest update to my home network (HSDPA to HSPA) is not well received by my phone. My battery is draining really fast since this upgrade.
Is there a way to enable ONLY HSDPA? I mean, HSPA is great for downloading and uploading, but battery life is really poor. I had very good battery life with HSDPA and I'd like to set my phone to this type of data connection.
Somebody told me to look for some entries in build.prop but I didn't find anything. Does someone know how to do it? Thanks

Hey, thanks for your help. Well, I'm not suffering battery draining for any other reason. I don't want to use 2G networks only. Just want to change HSPA to HSDPA. That way, I'll go back to having the usual battery consumption.
Any other suggestion?
HSPA is a term that encompasses High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) - if your network was using HSDPA, it was an HSPA network.
Enhanced HSPA (HSPA+) is an enhancement to HSPA that enables download speeds of up to 21Mbps and beyond, up from the typical 7.2Mbps. The Atrix is a 14.4Mbps compatible HSPA+ device.
So you saying you don't want HSPA, but want HSDPA doesn't make any sense. Do you want to disable the increased upload speeds? (HSUPA) or the HSPA+ speed enhancements? (up to 14.4Mbps) I know Samsung have an option to disable certain parts of the network through a hidden network, no idea about the Atrix though.

Yes, I want to disable HSUPA (what makes it HSPA) since it's killing my battery. I found a lot of info on Samsung phones but I don't know how to do it in a Motorola mobile
Sorry to bother again. Any solution yet to prevent phone from going on HSPA and stay in HSDPA? Thanks in advance
Just for your information, I found some build.prop tweaks to set HSDPA only, but none of them worked. Any ideas? Am I doing something wrong?
Thanks

BUMP... Still trying to set phone to HSDPA only... Any thoughts?
it can be done, it took me three weeks to figure this out. we had a flood come through here about three weeks ago and it did something to just one antenna on the tower, i dont know what it did but it prevented anybody using a phone on hsupa from using their internet on their phone, i called att multiple times on the issue with no fixing of the tower that was transmitting a bad hsupa signal, the same antenna was transmitting a good "3g" signal or "hsdpa" both of my 4g phones would work anywhere else in the world except for at my house where the bad hsupa signal was. so i knew i had to find a way to downgrade to hsdpa to get my phones operational again, no help from att as to when or even if they would fix the towers. att thought i was crazy because i was the only one complaining about it because everyone on 3g was unaffected, probably only a handful of houses on this one antenna, att locks you out of your phone from being able to go to 3g or 2g, all automatic. 3 weeks of this crap then one day i remembered when the atrix first came out hsupa was locked out, remember all the scoff att got for that one, so here's what i did to shut off hsupa and get my phone back running again:
1. make sure your bootloader is unlocked - not sure if this will brick your phone if it isn't
2. download these radio packages http://www.megaupload.com/?d=V0LDOGFJ
3. flash the one radio that says att shipping radio or something like that through rsd lite (this is the original radio that shipped with the atrix) and don't worry its safe to flash if you are on gingerbread..
4. reboot your phone and you will be locked into 3g or hsdpa thus locking out hsupa
5. if you want to turn hsupa back on just flash the other file
this method worked great for me and got my phone working great again and no hsupa for me anymore until att gets the tower fixed which may be never since i'm probably the only one on this particular antenna with a hsupa phone.
all we need now is a nifty dev that can hack one of these radios to shut off automatic network selection for those of us that are stuck on it.

Hey pal, your method worked! After flashing the old radio, the phone is on HSDPA only and battery life is way better, back to Froyo times. I don't really care about the enhanced upload. Download speeds are as good as they were on HSPA.
Thanks a lot.
Can you please upload those radio again? I'm suffering the same thing with my atrix. Thank you.
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.
I'm confirmed that my hometowm support the 21M hspa+ network,but why my gs3 can't lock the hspa+ network.When I open the data,H+ just showed at a very short time,and then it turns to H.
And I moddified the build.prop hsxpa=2,and flash the modem.but it just can't lock:crying:who can help me. thanks
I'm pretty sure that phones will only go to H+ if they actually need it. Hence you'll find that if you start requesting data, it will switch over to H+ again, and then revert to basic H when it's done. Probably not an issue.

and I have tried my white one and the blue one,it all can't,may be I should connect the network engineer
To expand to what anthropolyte said, the GS3 has a Fast Dormancy mode, where it'll connect to H+ network when is truly needed (heavy surfing/streaming, etc), and when the phone is mainly idle or doing light/periodical syncing, it'll switch back down to H or even 3G to conserve battery. As far as I know, Fast Dormancy must be supported by your carrier (which it does in your case) and must have a compatible phone to toggle between different network mode (GSM/HSPDA/UMTS, etc) to increase battery life.

but I have tried a lot of network things to do,such as online video,downloading sth,and etc.I saw there is nothing can even use the hspa+ network.I'll connect the network engineer and I think this is their problem.btw thanks a lot,and I'm a chinese user
mine alternates between 3g and H+ too. It bumps it up to H+ when I start using apps. The slight lag before it kicks in is not a bad trade off for better battery life.

In which case it's a problem with either your network provider or your phone. I'd suspect your provider primarily; give them a call and see if they can help.

Same here. 3G <---> H <---> H+ but when I start using apps like Youtube, H+ kicks in and everything is ok...
