LTE usage on non-LTE areas - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I'm thinking about buying the s2 skyrocket, and as I already know, LTE drains the battery very fast.
The problem is that I dont have LTE in my country and I was wondering whether or not the LTE will still drain the battery even when there
is no LTE reception, by constantly searching for LTE network?
Thanx in advance!

No, just switch to H+

AT&T LTE phones don't have the option to switch to 3g or turn off LTE, so that simply won't work.

I'm guessing the phone is unlocked... If you can't get it to change manually by going into network selection and searching for networks manually, install a non at&t modem. (Rogers, Bell) than try again. If you are on stock touchwiz than you're SOL.

It should let you as long as you aren't on touchwiz. Just go to the network selector, choose your network from the list, and then set it to GSM/WCDMA preferred. Or check use 2G networks only if that's what floats your boat. I'm on AT&T using AOKP and it just worked for me.
EDIT: Almost forgot, you have to redo it every time you reboot your phone.

It has nothing to do with TouchWiz. It's the modem. Use a non AT&T modem and you will be able to switch to H+ on a TouchWiz rom.

So many scenarios on battery life.
Signal strength, Apps, Wakelocks, brightness the list goes on.
You will have to play with it and give and take for your liking.
The best I've gotten was 3 days some odd hours.
Its a great phone you will not be disappointed.

With that said you need to do your homework first and READ READ READ.

So I'll just ask it differently then - Does the battery last a whole day (from morning to night) on non-LTE areas (auto brightness always on)
when only doing light-moderate use (just phone calls, texting, light apps like calculator, camera, playing a little music/videos, no gaming, no wifi, no internet)
Thanks!

LTE radio will not turn on if network apn doesn't provide it ..
So if network doesn't provide LTE , phone will connect to H+ if available ... No extra battery drain (from LTE) in this scenario.. I had a similar situation when I was on Starighttalk , they don't provide LTE , my location is an LTE market if I was using an at&t sim
Although it's a great phone , but it is getting old nowadays .. You might think of the international S3 maybe or an S4 .. Just my 2 cents..
PS :Custom roms aren't magic by selecting network preferred setting , you can do it in touchwiz with *#*#4636#*#* in dialer , but you have to use a RAT unlocked modem like the Roger's ones...

Does anybody get bad call quality, Because I read on some reviews that the call quality on the skyrocket is not the best...

Does the UCLA3 modem work for Rogers LTE?

I just switched to Rogers with an LTE plan and LTE SIM card, and my area is has complete LTE coverage but the best I am getting is HSPA+. Does the UCLA3 only enable LTE on the 700mhz band? If so, what is the best Rogers modem to use for LTE? Thanks!

Does the nandroid restore the baseband? I know a nandroid restores everyhting else but you might actually have to reflash the original radio that you were on before the UCLA3 version...not actually sure though.
This radio is the best for Rogers everything work great, lte as well and reception is great. At work where I only sometimes got connection at all, I have min two bars now, and internet works perfect. Thanks for makers and uploader

i concur.
lte picks up where the rogers modem doesn't I go between that and the telus modem (which doesn't do LTE but has good hspa speeds) It also does a great job in just automatic mode selecting the right band for low signal areas.
Yep I use it on Rogers with LTE working.
Also, someone mentioned a fix where you dial *#2263# to change the baseband to LTE only.. which works, but I stopped getting incoming calls and couldn't make outgoing calls when I did that.. fyi. Maybe it was just my case.

Not only data uses LTE network. When I used LTE data plan I got missing calls sometime (the call went directly into voice mail). Called rogers and the tech confirmed that calls work through LTE as well. If the signal of LTE is weak the call then bounces back into voice mail.

i've been switching between LA3 and KJ7 modems past 2 weeks...signal seemed great on LA3, but i'm not convinced it's good for me....
Consistently past several tests I get 2-3Mb down and 0.5-0.8Mb up on LA3......and if I flash to KJ7 I get 2-14Mb down and 1-3Mb up.....flash back to LA3 and it changes back....and flash again to KJ7 and back to other numbers....
In my area, KJ7 actually seems to be better, and I've switched back for now. I'm mainly around HSPA, not LTE though...
It also seems to be giving me better battery life...albeit we're talking difference of maybe 30 minutes to 1 hour...this phone is a PIG when it comes to battery life
So I've been using this modem since yesterday and I haven't been able to pick up an LTE signal but maybe Rogers coverage map is incorrect? idk but the 3g signal has been great
The only problem I'm facing (which I'm not sure if it's caused by the modem or something else) is that I couldn't send a text message to anyone but myself cuz it would fail... but if that person sends me a text first, then I can start sending text messages back no problem...
I registered for Rogers One Number, does that have anything to do with it?
UCLA3 radio works fine for me and I'm on Rogers network.
To check if your problems are radio dependent, why can't you just flash back to the Rogers radio? I believe it is on the same radio thread.

I tried that twice but when I check under Status it still shows the UCLA3 and not the one I flashed.
Also, I keep setting to to GSM/HSPA/LTE (Auto) mode but it keeps switching back to the one without LTE
EDIT - For some reason the APN settings were only for non-LTE access. Changed the apn to ltemobile.apn and now it works

What rom and kernel combo are you using

With all the development and new roms which combo are you using? I'm currently on nexus mod 4 stock UCLA 3 2.3.6 kernel getting outstanding battery life.
On NexusMOD 4 and was on romracers stockish0.3
just switched to faux010m UV-75 and UC to 1.4. Gonna see how that runs
I tried the faux kernel uv and uc but the silver stock ucla kernel is amazing for me with heavy usage
I would use juggernaught 5.0

I'm using Sky-ICS on the 2.6.35.11+ kernal. Pretty decent battery life, although I am not in a LTE area so I'm not sure how that would be on the battery. ROM is fast, smooth, and pretty customizable.

I have that ROM, it's not missing it.
And every single rom for Skyrocket has LTE Support, actually the phone hardware is always there, that I know for sure.
some ROM's don;t even have an option to choose and still applying apn works perfect. On AT&T ROM the icon will say 4G and small LTE under it, on Rogers it will say LTE.
If 4G is working there is no way you can be missing LTE as LTE is 4G just faster.

AT&T uses regular LTE which is just 4G updated it's called 4G-LTE, Canadian network is way more advanced.
http://en.wikipedia.org/wiki/4G
coming back to my original point, if your phone shows 4G sign and you don;t get LTE, two reason's 1) you are not in the range for LTE 2) your apk is wrong. This is tested and retested, just change the apn and get in the LTE range and see the magic.

well there u go, becuz I'm on rogers in Canada and LTE is LTE, 4 g is slower. Yes, the LTE radio remains active but the rom is incompatible with the frequencies of Rogers LTE = no LTE. That being said a RAT unlocked radio like kj7 may work, but 1) i highly doubt it, and 2) I never got around to testing this as the UCLA3 modem and kernels combo work great for me

no it only turns back after you reboot...
Entering a new APN should do the trick. Not sure what you should use on Rogers or Virgin. But for AT&T, they have different APNs for LTE versus non-LTE phones. So entering the APN info for non-LTE seems to disable LTE.
That dialer trick doesn't work, all of the options not containing LTE revert back to the original right after you select them.

This may disable it but it doesn't turn off the LTE radio in your phone. It still searches for an LTE signal and still yields the same battery life.

Depends on your goal. If you are in a fringe LTE coverage area, this will solve connection problems, and thereby improve battery drain to some degree.
But I see what you are saying. It prevents connection to a certain LTE network, but doesn't turn off the LTE radio.

[Q] Radio Flashing for Noobs?

So I've been having the same battery problems as everyone else. I'd like to disable LTE on my ATT 727. Knowing that I could force protocols on prior phones, I went looking for the options to find none. So I decided to flash CM10. I learned after flashing CM10 on my device that the radio needs to be flashed also. I've tried flashing a few different radios but it appears that they simply aren't flashing. Recovery goes through the motions but the version never changes. I've read rumors that I need to do a subsidy unlock but I haven't seen any real confirmation of it. Is that true? A carrier subsidy unlock must be done to flash over the RAT locked ATT radio? I would expect that to be in the noob listts with radios if so.
Baseband version: I727RUXLF3
Kernel: 3.0.49-cyanogenmod-g5756af3
Recovery: CWMR Touch v5.5.0.4 _sk8_
Thanks in advance for the advice. I really want to like this device. Hopefully between wakelock and LTE we can get it useable.

There is a dialer code you can use to access radio settings and turn off lte. I don't remember what it is offhand.
This: *#*#4636#*#*
^^Type into dialer^^
Also, try updating to a newer version of sk8's cwm.

Thanks for the info. I wasn't able to find the text you referenced to read it in detail. It looks like you're telling me that CM10 has a bug where the network mode can't be set for AT&T Skyrockets.

This is the same for pretty much all recent at&t smartphones. Last 5 I have had have had that option blocked. There is a possibility if you pull the sim card out, boot phone back on, use the dial code listed previously to set it and then put sim back in you might get the desired results. Not sure they will stick though.

Perhaps I've misunderstood but I thought I had read that flashing the Roger's radio would fix the problem as it's RAT unlocked (whatever that means).

you could also go to your APN's and switch to the non LTE one
this will stop you from having mobile data altogether in some areas but will give you the desired battery effect

Don't know about Rogers that is why I said at&t. I haven't even been able to get the rat selection screen to give any other option but lte ones on this device. On my lg thrill I was able to get different options by popping the sim out like I suggested but of course that is a non lte phone.
As a side note, I haven't seen much difference in battery life between running lte data or wifi data. I could see this as beneficial if in a non lte area or weak signal area.

The Rogers radio is the only one that is rat unlocked.

Which I have flashed. Does you know what the requirements are to disable LTE, to take advantage of the rat unlocked radio? I don't believe I'm in a good signal area and would like to at least try changing protocols. If I can't get this phone to a 12 hour life, it's going back.
Thanks!

You have to select search manually in the networks menu. Let the phone search and select at&t when it finishes. You can than change network settings. I do it all the time on aokp with a Rogers radio.

[Q] LTE problems?

Been on the iPhone for close to a year. I'm tagging out! Coming back to android and the ultra or maxx has been the device I've set as my decision. However I'm a tmobile user. Maxx has the battery life I need so I want to clarify before I pick one up what any glitches of the device may be on the network. I've been reading with the kitkat update there is some sort of issue with the enabled lte and not being able to utilize SMS/phone at the same time as lte data? Is this true? If so any possible way to remain on H+ without activating lte or inputting apn settings? Or has this been rectified? Lol.....rectified.
Any input anyone has is appreciated. And yes I know. I should get verizon. I've been with tmobile for 12 years. I just can't beat their price right now and I live in an lte city. When I go out in the county it's a different story. But one day I'll jump ship. Maybe intervention is required. But right now I wanna stay with the T.

"LTE Thunderbolt" on the play store will be your best friend while on T-mobile
Works wonders with moto devices, you can choose which exact signal the phone should look for (LTE included)
Great phone period. On vodafone with it right now, used that app to ONLY look for HSPA+ and everything is golden Lemme know if you have any other questions, but that app should fix ya up
Awesome thanks bud. I was a but concerned about that whole hiccup and was making me second guess getting it, but the phone seems to be the best choice for me out of any available android phone. Hopefully this will get worked out. Do you find it a little inconvenient to switch signals or do you just stick with the hspa signal permanently?

With the KitKat update. It's pretty annoying that I can't make phone call and send text message when it is on LTE. Gotta switch back to 2g , edge before sending text , make call. There is no option to disable LTE to stay on H+ .

That's disappointing. Unfortunately I just spent 400 dollars on one. Welp I guess I'll keep my fingers crossed. Glad I didn't trade my iphone off yet in case. Well I hope this can be tweaked. =\
You can switch the phone into gsm only using phone info. If lte is disabled you'll be fine on KK until they fix it. LTE/GSM works fine on 4.2. I'll link a copy of phone info to make the change. Please don't modify other settings as you can potentially permanently damage the radio. You'll get HSPA+ in refarmed areas. EDGE everywhere else.

Thanks for this! Are the odds pretty good that this will be taken care of in a future update? I feel like I don't expect it since it's not a verizon critical issue. Would this be taken care of in a future KK update or firmware? Thanks for your help so far everyone
I had talked to a contact of mine at Motorola and they were unaware of the issue til I brought it to him. It's on the list of things to fix.

Great! I'll keep my fingers crossed and I'll have the phone by the end of the week. Glad it will be useable!

You're doin it wrong GSM only disables the LTE radio.
If I'm understanding arcanexvi's post correctly it instructs to switch to "gsm only" and not "gsm auto", though it's circled in the illustration. Hard for me to speculate though until I have the phone in hand.
Lol you beat me to it. I can see the confusion though since gsm auto is circled in the photo. It's like sitting in the drivers seat getting directions from the passenger and they say left and point to the right lol. I'll let ya know how it goes when I get the phone. Thanks bud.

If the phone realizes you're not in the mode selected on the mobile network page it'll revert. I have it noted in the thread I created regarding this issue.

Ugh USPS apparently left the signature slip on top of my note in the mailbox with a signature date and note to leave the package with office staff
That's just cruel

Got it working off the bat with your instructions from the other thread perfectly bud. Thanks! How long do you think it will be before this gets tweaked and released?
