As you may know desire has a built in feature that monitors when you do need 3g connection and when not, so when you do not need it it automaticly switches to 2g. I have also read somewhere that this feature consumes less battery then being always on 2g. Is that true? I still heard a lot of people that are most of the time on 2g while they do not browse the internet, reporting decent battery lives.
So, as the title says, which is better?
2g uses less battery than 3g. Use 2g when not using data for the best battery life.
Whoever said that 2g and sometimes 3g uses less battery that 2g only needs to go back to school, its mathematically impossible if 3g uses more battery.

are you completely sure about that? my phone seems to be always in 3G as long as it is available and switchs to 2G if it cant get a 3g connection.
anyway, 2G is the best option battery wise.
there is a video from google i/o 2k9 talking about this. I think it's this one : http://developer.android.com/videos/index.html#v=OUemfrKe65c
I have used both modes for some weeks, but i didn't see any difference.
http://forum.xda-developers.com/showthread.php?t=688492
How about this? Does it apply to desire as well? I am curently using gsm only when im not browsing the net.
2g only will use the least battery.
Auto is great but the issue is that it will preferentially seek 3g. To seek 3g more power is required. (Now this is a negligible amount on its own). However if comparing the battery use in only a 2g area the 2g phone will last longer.

if you have signal i recommend to use 3g. the cells needs more power to have/transmitt fast data connections like hdspa and in that case the cellphone need less battery to connect to it. in Romania the network it's kinda new hardware, because we use cellphones later than anyone else and the tech was envolved when we first install the network, but remember if your cellphone go from 2g to 3g often, this will consume a lot of power.

So you recommend wcdma only? Even when I don't use the internet? Its true that I have signal most of the time, but I am on "gsm only" all the time, switching to wcdma only when I browse the net.
I would recommend GSM auto (PRL) from the testing menu ( *#*#4636#*#* ) then in phone information. Your phone will still use 3G but only when the signal is strong. Otherwise it will prefer 2G.
WCDMA preferred will try to force 3G even when the signal is weak. Consuming more battery.

2G only uses the least power.
3G only uses moar power.
Constant switching uses the most, it peaks at 600mA battery drain in the process.
3G only will only give you signal outages, therefore I would not recommend it. It is not widespread as GSM signal is.
Oh I finally know how to acces PRL options, thanks. But regarding this, I found this thread on the nexus one section, which says wcdma prl is better. Any of you know how accurate that is?
Edit:
sheek360 said:
He mentioned that gsm auto prl will save the user a bit more power because it wont force the phone to continuasly hunt for a stronger signal. Typically this option gives our n1's a weaker signal and slower data speed. But he said it depends on our network in our city.

Nvm, it wasn't battery related anyway. And I found what I needed. Thanks a lot.
Im back to gsm only, gsm auto prl didn't seem to be better in terms of battery saving.
I have tried several different APN's and none give me data. AT&T has eliminated the GSM toggle menu under mobile networks. It should have:
GSM/HSPA/LTE
GSM Only
HSPA Only
GSM/HSPA auto
How can we turn off LTE? and use only "4G" (HSPA+) My phone sits in my desk drawer all day at work and I'd rather not have it on LTE killing the battery. I'd also rather NOT turn off mobile data as then I can't receive e-mails or picture messages.
AT&T really is doing more harm than good by eliminating the GSM toggle menue under mobile networks.
SOLUTION:
1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect.

It's very strange that they would remove it from the Note II but allow it for the iPhone 5
I look forward to hearing the answer to this as well. Being forced to kill my battery if I'm not in an LTE area would piss me off.
just run juice defender. It will shut off your lte when your phone is locked and turn network data back up when you unlock the screen. It improves my battery by 1.6x-1.8x on my note 1. havent installed it on my note 2 yet, maybe after i see how the battery life is as is.

The iSheep wouldn't quit bugging Apple if they didn't include an LTE toggle. But AT&T can't touch the iOS software on the iPhone 5, which is probably why its on there.

The claim above regarding battery life doesn't help other people much without scientific testing. Battery claims need details on what was done and for how long, screenshots, screen-on battery time, and LTE signal strength.

So I guess we can conclude that att are real pricks and would rather sacrifice our battery life in the hope that LTE always being on will take some of the pressure off their 3G network
Even though I used LTE all day today, it really didn't affect my battery life. I know these chips are not first generation LTE chips and much more battery efficient.
I know this sounds contradicting but if I wanted HSPA+ only I could have very well purchased the international version.
I am hoping that every developer adds the option in their roms.s

att has forced this on the gs3 and the first note as well the only way to really get it off is to run a canadian base rom.
If you download "Phone Info" from the Play store, under device information, you should be able to choose between the modes and bypass ATT's bs.

This was taken from a Galaxy S III forum so they didn't take in the Note's form factor obviously. You just have to remove the sim, power on the phone, and then select your preferred network, and then power off, and pop the battery in.
It works though, I get my normal strong HSPA+ signal with NO LTE showing up.
Not sure if this was posted already but looking through the menus I found how to easily disable LTE. It's not around here and I read having it enabled eats battery. My HSPA speeds are 5-10 megs which is more than enough for what I do.
Anyway:
Settings
Connections Tab
More Networks
Mobile Networks
Network Mode
Choose GSM/WCDMA (auto connect). 2nd one from the top.
It seems this device sucks up battery at twice the rate of my former Note 2. Maybe this will help.

It just says 4G when you have LTE on the Galaxy S4. At least for Sprint anyway. I use Cyanogenmod so mine does say LTE. For AT&T I know for a fact that it says LTE on the top right of the 4G icon.
i use Menu Code *#197328640# to get rid of LTE on my Note 2. The option to switch to 4g only came on version 4.1.1. now its permanently off from the phone... no matter how many time i restore my phone.. :laugh::laugh::laugh:

I think some people are too obsessed with this notion of battery life. Sure, LTE might degrade it a little, but is it really worth disabling completely? I'm sure I wouldn't, I want the full features of a phone, whether that is data speeds or other features. Unless you don't have a LTE plan, then I understand completely.

I think that's backwards move there! Because I love my LTE speeds I get, almost faster than some WiFi at home!!
If you don't want lte speeds, then don't get a LTE PHONE!
And another thing if your really concerned about battery life then purchase a extended battery! They start out at 6200 mAh, 6500, 7600, 9300. Don't think they'll have to worry about battery life with one of those!:thumbup:
And tons of external back up batteries also. I have a16,000 mAh backup battery

I work for Sprint (not an official spokesperson or anything, so don't think my word is an official statement representing them), and I had a similar issue with the Nexus. I saw it again on the S6, so I tried the same thing I did on the Nexus 6, and it got way better:
Settings->Mobile Networks->switch to LTE/CDMA
Also be aware that if your bedroom is in an area of the house that doesn't get good reception, it's going to drain the battery trying to find it, like the other user mentioned above. Change it and see if it helps.

I would assume you're going to lose LTE by going to just CDMA....and Sprint's 3g is poor so losing even average LTE is not desirable for me.

CDMA only means you're not going to get LTE.
Regarding Sprint's service, it got very rocky when they started upgrading the network, but has gotten so much better, at least in my area. I get LTE pretty much everywhere I go now. I lose it at the gym sometimes, but that's about it.
Its such crap that Google removed the ability to toggle LTE on or off via a widget or toggle switch (you cant even toggle data on or off, you need to manually go to the networks page).
