using lte phone in hspa+ mode battery consumption - Galaxy Note 3 Q&A, Help & Troubleshooting

If using an international LTE capable note 3 in a country with incompatible bands, the phone will run on hspa+ mode, but the phone will be constantly looking for an LTE signal.
A phone consumes the most battery when searching for a signal.
Does this mean that using an LTE capable phone in a HSPA+ environment will cause a battery drain? I.e. its better to get the n9000 and not the n9005 if using an international unlocked phone in the USA.

Even if that is true m8 you can disable LTE in network settings and you will be fine so don't worry.

Does LTE consume more battery than HSPA+ in non LTE areas?

I've received conflicting answers:
1. It is constantly searching for LTE and wastes battery
2. It doesnt use any more battery because you aren't in an LTE area.
On at&t since you cannot change your network mode it will drain due to constantly searching for lte signal.

Will this make that not happen?
I need to know, because the ability to turn off LTE is my deciding factor between the AT&T US version and the International version.

USA unlocked with LTE?

will the N7100 or the N7105 work on Tmobile or AT&T's 4G? and will it work on Tmobile's HSPA+?
No LTE on international version.
You can get H+ on AT&T I know.. Not sure about tmo

So what you're saying is there is no LTE chip in the international version, correct?
I'm using the international one on the AT&T. Just have the H+ only but speed is good.

Yep. I was contemplating selling mine and getting the LTE version (on contract) but HSPA+ is fast enough for Netflix in HD. Fast enough for me! Don't need the carrier bloat, contract extension and battery reduction.
I'm getting 5-8 Mbps down and 750-1,000 kbps up on Tmo in NYC with my N2.

so what would you guys say? should I go for the Tmo version for LTE or international and skip the carrier bloat? I only have a 3G phone right now, is the increase in speed of LTE over HSPA+ a big enough deal? also will the international version work on Tmo HSPA+ or only on AT&T?
U should consider on battery consumption..i heard lte using high consumption battery..better ask community from att for note 2 thread it self..

Uhh... if you want to use it on T-Mobile expect 2G speeds unless you're in an area where they've started or finished the 1900 MHz refarm (even if they do, it'll be pretty much limited to a city or county, but anywhere else you won't get 3G/HSPA speeds at all)
here's a link to a website with reported sightings of 1900MHz refarm on T-Mobile:
http://www.airportal.de/
Also, the T-Mobile version of the Note II has support for AT&T HSPA as its HSPA radio is a pentaband (so it'll work pretty much everywhere else on HSPA), also the radio of the T-Mobile version is DC-HSPA, or more commonly known as HSPA 42mbps whereas the Internaltional and AT&T versions have HSPA radios with support for only 21mbps. The T-Mobile version also has LTE bands for AT&T and the eventual T-Mobile LTE network, but is currently DISABLED in the software, so we'll have to wait to get that unlocked (I also heard there'll be requirement of a LTE SIM card, but I can't say that for a fact yet).
In essence, if you're going to spend ~$700, get the T-Mobile one, at least you'll have warranty, better signal on HSPA, LTE support later for T-Mobile and AT&T, and as a result, you'll get a better resale value when its time.

I wonder if that's because it lacks the right bands or just because it's disabled in the software?

thanks for the info! I'll prob get the tmobile version after all. I am in a refarm area according to your link, but I wouldn't want to be restricted to my area and lose good speeds when I drive somewhere else.

Exactly, achu, are you sure it's possible to get LTE working on T889 on AT&T's network in the future? Please be certain when you state so, because we already have enough mis-info here on the forum thanks to the Samsung's decision on making *this* many variants. (already 14 or so)
Guys, I have the tmo version. This thing is amazing, and now I'm thinking of buying another one to send to my brother in the philippines. Not sure which would be the best model to buy, tmo US version or international version? Anyone from the phils who can cobfirm the bands use and iis it hspa or lte or something else??
Thanks

I have an international N2 bought in France (N7100XXALIH), and I am having trouble to get the H+ in Atlanta with tmo even though it's fairly well covered. I am stuck with Edge (which is quite frustrating) and tried to flash a few radios without any success. The tech guy from tmo told me that only tmo-N2 can use H+ so what you wrote is encouraging. Did you guys use a specific modem? Or did it work straight out of the box? Please help.
Just put your phones mode to wcdma it will only force h+ settings> moresettings>mobile networks > network mode choose wcdma if ur area has h+ it will pick it up otherwise no signal wont default to edge

I did this already and, as you mentioned, the phone defaults to no signal if no h+ is fetched, and is rendered unusable. However, my friend is able to pickup the h+ network with much more ease using a tmo GN1 (both phones operate on WCDMA in this case). So I suspect something with the radio rather than the hardware, no strong statement here. I tried to flash icsblaze and others without any success (actually had to recover my system several times due to major crash). Are there any tmo radios available for Jelly Beans?

[Q] Feedback required from Virgin Mobile Canada Galaxy S4 Users

Hey folks,
I am currently using an unlocked S4 from Wind Mobile on the Virgin Mobile network. It is technically the T-Mobile variant - SGH-M919V.
In comparison, the Virgin/Bell S4 is the SGH-I337.
My phone usually stays on LTE but it tends to revert to 3G in some areas, but never on 4G or H+. I had thought that the bands were compatible on the virgin mobile network, which brings me to my question.
Does your S4 ever revert to 4G or H+ when not on LTE? If that is the case, I am thinking of trading my Wind S4 for the Virgin/Bell S4.
Appreciate your feedback.
Thank you.
I'm pretty sure the M919 should fully support the 850 and 1900 MHz UMTS/HSPA bands, also you'd never see 3G or be able to do voice calls and texts without them.
I just got my SGH-I337M from Virgin yesterday and it definitely reverts to H+. So far it seems that it reverts from LTE to H+ after the phone has been sitting a while, and then if I start using the data it will kick up to LTE (probably doing that to save battery instead of keeping LTE on all the time?).
Who knows what could be going on with your unit. That is a Wind unit right? Maybe the software is different. One thing I know is that ROMs can show 3G/4G/H/H+ differently. Have you done a speed test while it is showing 3G? If it is true that you are falling all the way down to basic 3G/UMTS and not getting HSPA/HSPA+ then your speeds should be limited to less than 0.5 Mbps I think.
Thanks for the quick reply.
I managed to run a couple of speedtests when not on LTE. And they were around 2 Mbps down and 1.5 Mbps up. I don't think those are necessarily H+ speeds. But it's decent enough. Maybe then the reason I am seeing 3G is because of the way the ROM chooses to display non-LTE connections.
I double checked the supported bands, and it is true that the Wind S4 (T-Mobile variant) not only supports all the bands that the Bell/Virgin S4 does but the additional AWS band as well.
Is there a way for me to force the H+ connection on the phone, just to see that it works? Or should I possibly flash the modem/radio from the virgin/bell ROM?
Open up the Testing Menu, go into Device Info and see what it says for Network Type.
Make sure your wifi is off and hit "Run ping test" as few times and look at what it changes to.
HSPAP:15
HSPA:11
HSUPA:10
If you see these then it's fine, just icons are different.
Solved!
Okay,
I did a few things to verify that despite the phone showing 3G, it is in fact on 4G or H+ when not on LTE.
I went into ServiceMode by entering *#2263# in the Phone Dialer.
I forced non-LTE connections by changing the automatic preference to WCDMA 850 and WCDMA 1900 respectively.
These are the 2 bands that are 4G or H+ for Bell and Virgin Mobile Canada.
Then I ran speedtests to a close by server and got around 7 Mbps down and 3 Mbps, which are definitely 4G/H+ speeds.
Also, following @ChronoReverse advice, I found that the network type was in fact HSPAP: 15 and HSPA: 11 (screenshots attached).
So, in conclusion I can rest my obsessive personality and accept the fact that the phone is in fact capable & is running on 4G networks. It's a ROM thing I suppose.
Or in other words, the Galaxy S4 from Wind Mobile (or T-Mobile) is completely capable of running on Virgin Mobile Canada, Bell Canada, Rogers networks with full support of LTE and 4G/H+.
Embarrassed to say what a small little 3G icon does to a person these days!
Thanks for all the help!

[Q] GS4 users, 4G mode only?

is it possible to switch only 4G mode just like before it was possible to use only 3G or 2G or 3G+2G
8previous models)
Also interested in seeing if that is possible. I'm usually set to WCDMA only since I get HSPA+ most of the time. If I go into Auto with LTE it just cycles. Like crazy.
Sent from my GT-I9505
i ask this too because i do not have S4 yet so i like to know if pure 4G mode is possible, it even may save battery by turning off 2G and 3G if not needed. If someone has S4 pleace check it out if you are in 4G area, thanks.
On my unbranded device I have
Auto LTE 3g 2g
Auto 3g 2g
2g only.
Carrier branded devices will be different.

MetroPCS compatibility

Recently with the T-Mobile merge MetroPCS has supported bringing your own device, such as the nexus 4.
Most devices connected will use both Metro and T-mobiles towers, giving us overall better coverage.
The issue is that the Nexus 4 not supporting LTE by default won't connect to metro's network. So this halfens the merge, back to only T-Mobiles tower.
My question is, does anyone know how to connect the Nexus 4 to both networks? So far none of the LTE enabling mods don't work.
Sent from my Nexus 4 using Tapatalk
That's not possible. The nexus 4 only supports band 4 LTE, which is what t-mobile uses. However, metropcs LTE is band 2, thus making it incompatible with the nexus 4.
http://en.m.wikipedia.org/wiki/T-Mobile_US#Radio_frequency_spectrum_chart
Metropcs does have band 4 LTE, but that might already be integrated with T-Mobile and there'd be no distinction between the two networks.

You shouldnt need to do anything to get your phone working on metropcs gsm except get a metropcs gsm simcard(no the ones in their old phones that had sim cards will not work), change the apn to metropcs lte (fast.metropcs.com) and of course activation. If youre only getting signal on 4g then you might have your phone on lte only. Be sure to enable lte/gsm only that way it can go down to 2g/3g/H. And it techinally runs only under tmobiles towers so if your area has weak tmobile towers thats the problem. you can use everything on the nexus 4 including band 4 lte if its included in your area. Metropcs is slowly becoming another mvno on tmobile. They still have cdma phones but theyre being phased out. Band 2 is most likely referring to their cdma LTE which is a differently system all together. Im on MetroPCS GSM. obviously you cant use cdma bands with this phone but on metropcs gsm you'll be fine. You get hspa+ and lte. Its quick and cheap and works pretty good. I get speeds ranging from 8mbps to 25 max when on lte. I flash phones and unlock phones to metro all the time so feel free to ask me any questions
