Forcing 4G/LTE off to save battery - HTC Vivid, Raider, Velocity

Using the Telstra based roms, I can turn 4G/LTE off and my battery easily gets me through the day, with 4G on, I have to recharge by 1pm.
On at&t based roms, there is no way to turn off 4G/LTE when you are in Australia, as all of Telstra's APN's support 4G/LTE, there is no apn you can select which disables 4G/LTE, in the Telstra roms there is an option under settings > Mobile Network which allows you to select 3G only, *#*#4636#*#* forcing to wcdma works but doesn't stick.
is there a mod that could disable the 4G/LTE modem or is this something that needs to be cooked into the ROM?
Maybe I could just kill the 4G/LTE modem "device" via a script in the console?

Get a non LTE enabled simcard, or use hdspa apns and delete the LTE apns, this will disable lte.

Why, especially when the carrier Tel$tra doesnt do non
LTE apns
Stock ROM from this carrier gives the option to just switch it off
Surely this can be cooked into other ROM's

in Australia, all SIM cards from telstra allow for 4G/LTE and all APN's use 4G, the only "odd" sim cards are the iphone ones or the ones that were 2G only, the only way to force LTE to stay off that I am aware of is either using the MIUI rom that doesnt have an 4g/LTE modem driver and so wins by failing, or using a ROM based on the Telstra rom which has an easy switch to turn off 4G/LTE

4g/lte modem driver? 3g/lte is handle by one single modem module...

I'm no ROM developer, I don't know the first thing about the internal devily going on inside a handset, I am only aware that the MIUI ROM is incapable of 4G which to me would point to some difference in the drivers or config, whatever.
The Telstra ROM can turn 4G off, the MIUI rom doesn't have 4G and the at&t rom defaults to LTE as much as you fight it in Australia.
Now that everyone is done poking holes in my knowledge, does anyone have anything constructive to add or should I just give up

i have mine set to GSM auto.
what does that mean? i want to save battery

where do you have that set, under *#*#4636#*#* ?

makes me wonder why more devs dont use the telstra rom as a base switchable lte tethering built in higher clock speed seems to be a better base?

[Q] Would like to set GSM,LTE

Hi,
I noticed at my work my Edge is stronger then my LTE but LTE works better and of course faster then Edge. I am asking if anyone knows how to force only GSM for calls and LTE for data. I go through the options and notice many settings but LTE is always "LTE AUTO" I also use the hidden menu *#*#4636#*#* and set LTE only or CDMA, LTE Unfortunately I am on Rogers and CDMA does not allow my calls to go through and LTE only is exactly that only LTE. Both those options work great but of course drop sporadically which I can live with except the no phone part. What is the point of having a phone if you have no phone reception working on your phone.....
So my question is simple, is there a way to have only GSM and LTE set up or at least GSM and 3G/4G but with out the E network which ever that is.
Thanks
JB
No one?

Are there any Mods to keep LTE active in low reception area.

You could force LTE only, but then when the reception drops off, you'll have zero cell service.
It would be nice if there were more options offered for preferred networks. I leave mine on WCDMA preferred, and just do without LTE until I want/need it.

[Q] is there any way to keep the phone from using LTE?

my phone is unlocked and i use tmobile service..
they just switched on LTE in my area.. and its working great.. i assigned a new APN (fast.t-mobile.com) and i get upwards of 18Mbps.. but..
in my house.. the LTE signal is 1 bar.. most of my calls go straight to VM and i sometimes dont get texts for hours..
in my house the 4g signal which was the default before is 3 to 4 bars.. i never had a problem receiving calls and texts when its on 4g.
so it seems now they have LTE service the phone favors that no matter what the signal is..
i cant find any options in the settings to turn off LTE and just use 4g.
i guess you can disregard this question.. i installed CM10.2 and it has the option to only use WCDMA instead of LTE..
this fixes my issue

no the original firmware did not have the option to select GSM/WCMA/LTE only.
the CM10.2 has 3 options.
WCDMA/LTE
GSM/WCDMA/LTE
GSM/WCDMA only.
along with a use 2g network only check box..

I can't really help you but as far as I know LTE is already unlocked and working on all international S4 Actives. Mine certainly worked perfectly out of the box - although I turned it off promptly because I have ****ty 4G coverage where I live so it was nothing but a battery drain for me.
Are you sure you have a 4G sim card, and that you are in an area where 4G has coverage?
If you go in under settings > connections > more networks > mobile networks > network mode don't you have the LTE option at the top?

Im not 100% but i got the textmessage from my provider, so i recon they only send it to people who are able to use the 4G.
Yes, i am in a 4g coverage area
i dont have the LTE option at the top no. i have:
- wcdma/gsm
- only wcdma
- only gsm

Well then I really have no idea - the only thing I can think of is that you might need to replace your sim card if your provider didn't already do so in advance of the 4G rollout. Hopefully someone with more information might step in here, but the international version is LTE capable out of the box. If you don't hear anything else I'd suggest to try and contact vodafone and get a clear answer from them first.
If you check the mobile networks in your area and don't see anything that supports LTE, you may just live in an area that doesn't have it yet (people get 4G and LTE somewhat mixed up - 4G is the overall identifier for a whole class of technologies with "4th generation cellular networks" basically while LTE is technically one of those technologies so, it should rightfully be classified as 4G in most respects.
Having said that, the only way I got my GS4A to function in LTE mode - meaning it actually shows LTE in the notification bar under the 4 with a small G and LTE underneath it - was to go into the service menu (*#*#4636#*#*) and change the preferred network type to either LTE only or LTE/GSM auto (PRL). Once I did that the radio would reset and connect and then it would be in proper LTE mode. Doing a speedtest with the Speedtest.net app shows LTE as the connection whereas with my standard setting which is WCDMA Preferred (T-Mobile AWS) it'll just show as "4G."
I've had no luck making alterations in the Settings/Mobile Networks section, I have to change it in the service menu to get LTE functional. I don't use it because here in Vegas where I live (specifically my home location) the LTE mode gets me about 1-2 bars of signal (about 8-12Mbps) whereas the WCDMA Preferred setting pulls in 5 bars rock solid and 25-35Mbps.
Can't do screenshots or I'd add them, I'm running the pre-release MI2 ROM presently and that aspect is borked.

I can check my area on the vodafone site. I live in a 4G network area 100%!
i guess my wcdma is sufficient then.. didnt experience speedboost tho..

That would be because you're on the i537 from ATT, rather than the i9295 that this discussion is about. I checked google and vodafone holland does indeed use LTE on the right bands in its brand new rollout, so it isn't that - most likely it's his sim that needs replacing or it's just not activated on his account yet.

No 3G!! service loss when on "cdma only" mode

My phone is sim unlocked, using viper one rom, i'm always stuck on gsm even though my carrier "ooredoo algeria" supports 3G, i have checked and the cdma network frequencies are well supported on the device, how do make i the phone use 3G.

Have you tried going into *#*#4636#*#* and scrolling to the bottom, and changing the frequency to WCDMA only? Also, if you have a SIM card, your phone is GSM. CDMA phones are always without SIM cards, unless they support 4G (since 4G needs a SIM card to work)
ooredoo dz network mode switch must be Automatic

Hey Abdou, you have to put your network mode on "automatic" and ooredoo's network will choose the right netmode for you
Problem solved

Thank you for the reply, but i already fixed the issue, i was a noob when i asked it and i didn't understand what cdma and gsm meant i thought cdma meant 3G, but now i know that UMTS means 3G haha, and that i am on a gsm network, i figured it out.

[Q] XT1053. Preferred network type question. No 2G/3G ?

Hey Guys!
I'm from Argentina and I have bought (via Amazon) this amazing phone. It is the Developer Edition 32GB, XT1053. I think it runs the T-Mobile rom. I bought it because it is the global GSM version and its LTe bands works down here (same bands as US) well.
So far so good with this little and fast phone, but I was really surprised when i went on to check the preferred network types options, and found I only have 2 options: Automatic or 2G. There is no "3G/2G" option as I use to see in other phones. Normally you would expect 3 options here:
LTE (which includes 3G and 2G also), 3G (which includes 2G also) and just 2G.
Thing is, so far I don't mind this since Its cool to have it automatically, the phone will always try to find LTE and if not, 3G... and if not, 2G. The thing is, Argentina is currently setting up LTE over the country these days (yes, we suck), and in the future the operators 'might' charge an extra cost for using LTE instead of 3G, and that's what worries me... not having the option to limit the phone to 3G/2G was something I wasn't expecting and honestly I don't want to flash the phone to another rom, not at least in the near future.
Anyone knows if this "Automatic - 2G" setting is normal to see in this version ? Do you know if there's some kind of workaround to make it work under 3G/2G only in case I need to avoid LTE in the future for extra fees and so ?
Thanks for your help guys!
Edit: Forgot to mention, the phone came out with 4.4.3 but I upgraded it via OTA to 4.4.4 right away.
Yes the Automatic - 2G option is normal for the xt1053 retail stock. Android has hidden menu that gives more options tho.
Use this app to access hidden menu: https://play.google.com/store/apps/details?id=com.snclabs.radioswitcher&hl=am
Scroll down to where it says set preferred network type and change to whatever you want. gsm only being 2g, wcdma only being 3g, and so on
If the setting doesn't stick after reboot you can try toggling data off then on after changing the setting. try a few times it will stick after reboot.

Thanks man! That app will be really helpful to me if it happens that the operators start charging extra fee for LTE use in the near future.
Btw, I don't understand that much all that names. What would be the options for having 3G and 2G ? Should it be "WCDMA preferred" ? (I guess that takes away LTE) I will not use it under 3G only since I will be without signal if I happen to run into a 2G zone. (yes, we still have a lot of 2G zones in this country )
Thanks!!!!
