I know some Verizon phones have this, but does anyone know how to disable LTE and force hspa on our note? Just would be a serious boost for battery life when LTE isn't needed.

Saurom ROM has that capability. You'll need to root and flash a ROM to get this afaik. I'm on Saurom 7.0 and it's functional.

Thanks for the reply. Was hoping i didnt need to root/flash atm. Do you notice battery life improvements with this mod?

Personally, I don't ever turn off LTE considering that the way it's supposed to work is that while in a non LTE market, it defaults to HSPA+ anyway. And I've read that the lack of LTE doesn't interfere with battery life. Maybe I'll try for a day and see.

Yeah mine does drop to hspa inside some buildings but LTE blankets my entire county and surrounding ones. Basically I was just curious if forcing it to use hspa would conserve battery (in theory, it should). I'm surprised there aren't more threads addressing this.

I'd like to figure this out too. I was using my Note with my old S2 sim card for a couple months (bought the Note used), and didn't know there was an upgraded SIM card for LTE users. Since upgrading to the LTE Sim chip, my signal bars are around 50% signal strength and I think it is the culprit to draining my battery so quickly. When I used the HSPA+ chip I always had full signal strength.
Are there any mods anyone knows of or ways to update any custom rom? I'm currently trying out the BlackStar ICS Rom.
Thanks!
Canadian ROMs have the Network Mode menu in settings. I don't believe it comes from the Radio so it must come from the settings.apk. Here is the settings.apk from the Rogers ICS ROM and it is already deodexed. Do a nand backup. Then copy this file to your system/app folder overwriting the one included in the ROM. Fix permissions and reboot your phone. You should then have the Network Mode menu in your settings. Let me know if it works.
I'm pulling the trigger now. . .
I'll let you know infive if it worked, ten if it didn't.
This could be GREAT!

Please do. I suspected this would work for some time now. When I installed the KOB4LT mod awhile back it installed the settings.apk from the GSII and it worked fine except there was no settings for the s-pen. Should work on any of the ICS NOTE stock deodexed ROMs. And if your stock ROM is not deodexed just delete or rename both the settings.apk and the settings.odex too
This would be interesting. Definitely helpful since so many reviews said LTE kills battery faster than 3G.
This is why I went with the Rogers stock ROM instead of the ATT version. Network Mode, HotSpot allowed, and no carrier ID on notification bar.
Daaarn!

turn off lte att note
i came across this thread as im looking for a desktop widget to turn lte off on my att note 3.
theres a few reasons for this. I hadnt thought about battery life until i read this but it cant help but increase battery life. this is because lte and hsm are two different radios. the gsm will always be on to controll the phone and sms functions and i believe the mms functions.
but simply here in the bay are most areas hspap seems to be faster.
lte upload is always faster and it penetrates buildings better. but i switch back and forth and do tests all the time.
this is a very urban area and hspap seems to have 5 bars a lot more than lte.
7.1
ill do a random test for you from where im typing this.
hspap 7.13 down 1.10 up. 5 bars. lte 4.12 down 3.76 up. 3 bars.
and as soon as i get to two bars lte seems to throttle below 1 down and stays at 3 up.
whereas hspap never goes below 6 down until its lost reception.
so anyhow i switch between the two without a rom by doing this
*#*#4636#*#*
device then i change the radio from lte/gsm auto to gsm auto.
that works immediately
now all that im lacking is a simpler one click way to change the setting.

I got an S3 a couple of weeks back.
I've noticed that the battery duration is subpar.
I haven't even rooted the device yet and it doesn't seem to be the same for everyone.
On the pic attached you can see that it has been a few hours since disconnected and it has already consumed almost half of the battery.
I wasn't doing much other than about 20 minutes of web surfing, 3 or 4 texts and about 15 of playing music for my car stereo through the aux. Other than that nothing, no pics, no calls, etc.
I'm on 3G (H,H+) all the time. Do you think that's the issue?

Depends. Please use the dialer code *#0011# (or *#*#0011#*#* on AOSP-based ROM's) and check if the RRC-state goes to "IDLE" when your phone has not transferred any data for some time and HSPA is active.
If not, your carrier probably does not disable Fast Dormancy or you have Fast Dormancy disabled for whatever reason.
Please, if rooted, let Better Battery Stats (free APK here in Xda) record the Wakelocks across several hours and make a screenshot of the Kernel wakelocks and Partial wakelocks.
All I can see from your current screenshot is that you're constantly discharging and probably are on an older firmware (Upgrade!) since it doesn't include the Fix for the cosmetic issue causing the Cell standby being battery drain Nr.1
Are you using Apps like Skype or Facebook? Both are known battery drainers.
Have you been in low-signal or no-signal areas?

Thanks a lot for the reply.
I'm in Mexico and we haven't had the update released here. That's why I haven't upgraded yet.
I'd love to go to CM9 but as it stands I don't want to take risks with the modem, the scene is kind of young still.
I'm not using skype or facebook. I do have them installed but I don't have them running. I actually have sync for FB disable.
I'm very willing to uninstall both if you think it will help.
About RRC-State:
If I'm on wifi it says iddel.
The phone seems to go to HSPA only when downloading something and stays on 3G while idle. While on 3G RCC State reads "FACH".
How can I enable fast dormancy?
By the way, since 12 am today, I have downloaded less than 7MB of data from my mobile network. Anything else has been over wifi.

If it doesn't go down to IDLE then fd is confirmed off or not working. However not all providers support it so it's not that easy.
You can try this, but do a backup of the corresponding files first and of course replace wherever required the values with your provider's:

The problem is, your phone keeps a full-fledged high-speed data connection open at all times since it or the network is unable to go to Fast Dormancy. Open 3G/HSPA connections drain the battery faster than you can look. Talk about carriers sucking you dry =)

The modem doesn't change when flashing CM9. You should flash the BFLB modem though since otherwise you get issues with voice calling.
Plus, you can always go back to stock by flashing your (or a close) firmware from samfirmware.com through Odin.
I highly recommend trying CM9 =)

Thanks a lot for the help. I don't think I have the data required for doing that mod for fast dormancy. Most likely that is the culprit then...
I was waiting to root and such because of the flash counter but I guess there is no point in waiting. The phone like this actually doesn't do much for me. It's a pain to be concerned about enough power and I totally need to have the data on all the time (critical work emails). I always carry a backup iPhone 4 in case I have problems with my main android but I rather just use Android all the time (it rocks!).
I guess I'm down for CM9. Just one more question, my firmware doesn't appear as it is on samfirmware. How can I find out which one is closer to the one I got right now?
Edit:
Actually I found it. It wasn't there before but it is now. It might be newer to what I got right now.
I rooted my device and made a nandroid.
Just for research, instead of putting a new ROM I'll try to do a bbs log of my phone as it is to try to find out the reason for the drain although it might very well be the carrier config.
Hello, I have been thinking about how to automate the use of 2g and 3g. Now to switch from one to another must go to settings and change it manually etc etc, google dont allow to do direcly otherwise there is not widgets or anything
As you know, 3g is much faster but it takes a lot of baterry, while 2g is slow but it doesnt waste too much battery, so for example when I turn screen off I prefer to be connected in 2g, or for example when my battery is <20€, or whenever I want.
I found this app
http://forum.xda-developers.com/showthread.php?t=739530
But is only compatible with Cyanogen. I would want to get this working on our Roms or on our stock firms. There says there is a possibility but we would have to resign the rom or something, I dont understand very well what do they mean. I would try but is a risk because If goes wrong Im gonna lose everything and Im not very experimented with this, has anyone here tried this? Works on stock ICS with locked bootloader? How do we could do?
Thankss

android doesnt allow programatically switching between 2g and 3g. Thats the reason why most of the switching apps just work as a shortcut to the settings page.
There are workarounds that are employed by juce defender and tasker and probably some other apps too but they only work on certain roms, usually AOSP or Cyanogen derivitives.

Sorry, it might be a myth for you but practically, with the same use; my battery last about 24 hours with 3G always activated and about 3,5 days with 2G activated. It's a fact... But It might be linked to differences between 2G and 3G network cover and quality... I don't know.
Set your phone @ 3g only :angel:
but yes... it has most likely to do with 2g/3g switching
Yeah I know that android doesnt allow switching it automatically, I know there are methods that only work in Cyanogen, thats why I open this thread, lets see If we can find a solution for our stock firm Xperia S

This mod work on my Neo 2g/2g+3g/3g, but need some edits to work on XS...
Just side track, Nokia asha 300 uses 2g on standby, only when traffic exceed certain amount, it changes to 3g, and once you close the browser, it returns to 2g. Quite amazing though

If you are getting over 3 days then you must never ever turn the screen on or do anything with the phone.
anyone is interested about getting this feature? I have investigate about re-signing our firm to make it compatible with the Mod, but they talk about resigning .zip flasheable files while we use ftf files. Maybe there is no way to get this mod in our stock firms, or it could be only compatible with custom Roms which are installed through recovery with zips
any idea, any experimented user who wants to involve here?
um.....am i being slow? or does this option not already exist? wcdma preferred/gsm......that just swtches between the two depending on what's available?
Depending on your netwerk operator there shouldn't be a big difference in 2G vs 3G battery use. The XPERIA S supports fast dormancy, which will reduce power usage while connected to 3G. XDA-TV has an item about this subject.
Long story short, it isn't really necessary unless your operators coverage is bad. Then it would be smart to keeping on 2G.
Sent from my GT-P7510
I couldnt find an app either. One simple work around though. After selecting GSM/WCDMA mode, press the home button. The rule is to keep the current settings page in background. Switch it as and when necessary. Simple, not a concrete one though!
According to Sony the standby battery life is nearly double when using 3G in standby so not sure why you'd want to do this.

For example where I work is a poor coverage on 3G (it's inside a factory). When forced on 2G I have 1 and half day more battery. The problem appear because phone try to stay more on 3G, if the 3G is poor or zero than is switch on 2G (if exist). These switches drain the batt. So I force on 2G and when I need internet connection I set on 3G only and I activate data. For that reason a switch 2g/3g in toggle is very usefull (I have it on my Neo but I want on my new SXP too).
Ok so I did this and it helped streaming a little bit.
http://forum.xda-developers.com/showthread.php?t=1632687
Then I tried something else that doubled my internet speed it may not work on non sense Roms, but you can try it.
Open your dial pad, type in *#*#4636#*#*
Edit:tap on phone information,
then go towards the bottom of the page. Tap on "set preferred network type" then select CDMA/EvDo/GSM/WCDMA/LTE auto, then your 3g should turn off then back on. Next go towards the very bottom of the screen and there is a button that says toggle dns I believe. (Sorry, I'm on my phone so I can't check) hit that so it says 0.0.0.0 allowed. Then all you have to do is tap your home key and it'll save by itself. I have noticed that this won't stay there if you restart your phone, but once you get used to it it's pretty quick to set. I don't reboot every five minutes so it doesn't bother me. It's a small price to pay for fast internet!. My internet speed used to be about 200-300 download, now I see up to 2200Kb download.

It kills some if you pick the wrong one. figured that out right away. Pick specifically the one I listed and you should be fine. I've been running like this for about 2-3 weeks. By the way I'm on ota, dev unlocked, rooted, on viper Rom, and awesome sauce kernel.
Sorry, to answer your question...I do send and receive text and picture mail, send and receive calls (regular number and Google voice number). Now I just have really fast internet.
have you also checked if you're not roaming without knowing?

One test is not definitive.
Do 3-4 with it off, 3-4 with it on, and a couple with it off

That sounds like that menu that you go to to mess up your phone from roaming on the 850 band.
It's all a myth to me. If I can get 2500 on a rural tower but go to another and get poor speeds then nothing I do to my phone is going to change that except for roaming of course or maybe toggling in hopes to get on another carrier if the tower has more than one active and it's the air interface congested not the backhaul.
Sent from my C64 w/Epyx FastLoad cartridge
Though changing this could in theory improve speeds in specific scenarios, its unlikely (and proven when I did a similar test on androidforums.com) that the masses will gain little if anything from these changes.
What we have confirmed is that if you are experiencing slow speeds, the cdma only setting can drastically improve them. The LTE cdma evdo setting is trying to (in some areas) connect to the enhanced cdma technology that is not yet available in most areas, thus the phone ends up on evdo or 1x speeds.
Problem is, the average user has no way of accessing the tower information to even know what areas are complete, in progress, or not effected. Thus results will vary for literally everyone.
And as mentioned, some changes there will result in loss of voice, data, text and or mms

I have reflased to stock 4.04 and have downloaded every radio possible and I get same results. I have seen great results when it says H or H+ with low bars. Any help would be nice. If I cant find a soultion I'll sell it and go back to the mini S 4g lol

Does it hang only with the stock browser? Have you tried FF, Chrome or Dolpin? Try to d/l 7/26 GApps through Goo and see if that moves along well.

well that didnt work. Put back to factory ...going to sell ...anyone interested let me know. I do have it already posted in craigslist in the socal orange section. thanks everyone for the help
Well some success...I did one for the road. Reflashed to Saurom 7.0/7.1(Ginger Bread) and used the tmobile blaze and it actually works..here at work at my parents it hit 11Mb/s ! at my house though it cant get out of it own way. So 10 flashes and over 10 hours of fiddling...here ya go

inconsistent speed
525iEnjoy said:
I have searched and read and searched some more, so I joined here to see if anyone has a form of an answer.
I have a i717 Note rooted, unlocked and flashed to CM10. I have full bars and it says H+ and when I go open my browser it hangs. I used Speedtest and it gives me .5 Mbs/s . I have reflased to stock 4.04 and have downloaded every radio possible and I get same results. I have seen great results when it says H or H+ with low bars. Any help would be nice. If I cant find a soultion I'll sell it and go back to the mini S 4g lol
Ugh i cant post my screenshots!!

You can use any ics/jb rom you like and use ics blaze modem.The tricky part is how to get consistent speed which I think I found it.After flash the rom and modem You need to reset your network,I used fresh network app from market(must be not in the same area/walk around)after that test the speed using speedtest app,when you acquire very fast speed stop there do not reset the network again or turn off your phone again.If you do that your phone will be slow again and you have to repeat the step again.I tried many rom(ICS/JB)the best modem I think is icsblaze modem,also trying all that #combination thing.The best solution for me is to walk around to get the best network first.I got about 7-10 mbps down and 1-1.7 up using that method
I was wondering if anyone has had any luck changing the band on any of the 4.2.2-based roms?
to be sure, i mean making the band "3g" only by dialing *#*#2263#*#* and then changing the band.
In all the 4.2.2 based roms i have tried, trying to go into service mode by any means results in an empty service mode screen with no options to select from.
my need to change the band is so that i can get out of the perpetual "H" or "H+" mode that eats my battery like no tomorrow.

If you are using the ATT network, then I'm afraid you are stuck with the automatic band selection you are seeing now.
ATT networks are RAT restricted for this generation of device, and manual band changes cannot be made, regardless of the ROM you are using.
How nice it would be to drop back to an edge 2g connection at work and enjoy the battery life, like I could only 1 year ago using my inspire 4g, But the note will not allow it on this network.
Several other networks are able to change at will.......(C'mon ATT !! Seriously ??)........sorry......g
The Collective Room has a 4g(I think modem)on it works good but I like Rootbox better not 4g do http://d-h.st/TYO or look around cheers!!!!!!!!

Its screen time/ brightness that eats battery. Why would H to H+ affect the battery? That change is an indicator of signal strength/distance to tower not what your modem is doing.

That's what I was thinking. Kind of noob around here and with this whole rooted and rom thing but I'm liking it. Haven't had alot of time to search around but is there a way to change the screen time? i know the brightness yes but wasn't sure about screen time. Sorry if a stupid question

Change screen time by using screen less.
Less brightness is easy using the slider on the status bar.

While i agree that screen time has a lot to do with this, i am talking about battery being eaten away without the screen being on - like 6%-12% drain per hour range. This is probably network related. For example, in my tests, keeping the radio on an LTE band would induce such battery drains. For comparative purposes, on the blackstar xi rom i was on before, battery drain was ~1.5% per hour range when screen off.
Just in case someone is wondering, these numbers are based on fresh installs (after full wipes x2) of several of the latest 4.2.2 roms (the latest (3/13, i think) collective rom included). the brightness is set around the 10% range. and the percentages are taken after the rom has had a chance to "settle down" (i.e. maybe 5-6 hours into it).
Also, in case someone was wondering, i have tried resetting the battery stats when installing a couple of roms (although this should be a non-issue) without any effect on the battery life.
Furthermore, there is a preponderance of evidence to support the 3g/H/H+ battery saving method (for quick summary, google *#301279#)
gregsarg - im on bell network in Canada.
Thanks for your comments so far, guys. keep 'em coming.
Also, it would be great if you guys could share some of your battery drain experiences with the new 4.2.2 roms. Perhaps stating the rom name/version, whether data is always on, and any battery saving apps/tips/tricks used?
Edit: Another thought is CPU usage - and ive tried underclocking, trying diff kernels and governors just to get marginal benefits.
hello? bump
What baseband are you using? Try installing a Canadian ICS baseband/modem and see if that allows you to change your bands. They are not locked like ATT modems.
Uclf6.. I think that's the att one.
Latest Canadian ICS modem i could find was Uclf4. Let me try that.
Is the latest ucmb (sp?) Modem locked too?

Actually, i also wanted to find what sort of drain are others seeing with data on, screen off?
Any modem that was released with at&t ROMs will be restricted. Canadian released modems or the Singapore ROM modem should allow band switching.
Latest Canadian modems can be downloaded from here:

Thanks Agoattamer and rangercaptain. I tried MUGLF4 since im on bell - still no dice with the band menu.
*#*#BAND#*#* shows up as a blank screen.

any other ideas? maybe its a rom thing..
The ROM has the menu selectable band "Use 2G network only", so I think its a modem thing. I used an older Bell modem last year, and it had the service menu unrestricted.
I m using china vf695 4.2.2 6180 can I go for LTE mode ??
