[Q] Any overheating with 3g/4g lte? - Xperia Z2 Q&A, Help & Troubleshooting

please guys can any one tell me if there is any problems with overheating when using Internet with 3g or 4g Lte.. i used the first xperia Z and it was getting very hot when using 3g Internet only for normal using and i read also problems with z1 about overheating as well.. i really want to get z2 but am afraid of i will get the same problem
please guys share your experiences with this problem if you have any

I haven't had any over heating issues with long time browsing or video viewing. Rumor has it, long 4K video recording will cause heating issue.
Just read something on Android Central stating Z2 uses heat pipe tech to aid in cooling.

thank you for ur reply, but can you be more specific.. you said you used the phone for long hours on browsing and video playback without any problems with overheating BUT is that on 3g or 4g Lte,, or normal wifi?
my concern on 4g Lte. i want to get this phone with T-mobile contract for 2 years, so I want to be very sure of this issue which i had it on my first xperia Z
plus if you can also mention the battery drain how is it on 4g or 3g which one you use..
thank you so much and i wish to hear from more people on this specific situation

Doesn't look like a heatpipe there: http://www.xperiablog.net/2014/03/30/xperia-z2-disassembly-guide/
More like some standard issue aluminium radiators.

Watching MLB on LTE. In any event, signal strength will play a part in this experiment also. Let's see what other users have to say.

Guys, I have a problem. I relative of mine is going to buy me a Z2 from Taiwan. I live in Romania and I wonder if the phone will be compatible with the 3 and 4G network in my country, since it was made for Taiwan.
Thank you!

Find out what bands your carrier utilizes and check the specs for Z2 and see if they're included.

I see. But where can I find those specs? On the box? The phone is going to be bought online. The box will only be seen after it's paid.

1900 (Band II), 2100 (Band I) MHz
GSM GPRS/EDGE 850, 900, 1800, 1900 MHz
LTE (Bands 1, 2, 3, 4, 5, 7, 8, 20)

Thank you!

Make sure the LTE bands (if available on your network) your network utilizes are listed.
Incidentally, I apologize to op for highjacking this thread.

If the Z1-C6903 had all the bands required by my mobile operator, then Z2-D6503 does the same and even has some more. Therefor, I'll look fot D6503 model number.
Thank you and please accept my apologize if I was off topic and also forced augie to be off topic too.

I'm Romanian too and I'm also waiting for Sony Z2 to be available. I looked into it and Romanian carriers use 3 and 7 LTE bands (1800 and 2600 Mhz).

T-Mobile 3G?

Hi guys, I am involved in a deal regarding an international GSII, and have been reading conflicting reports on this.. GSM arena says it supports the 1700 and 2100 bands but I have read other things that say it only receives EDGE?
Any help is appreciated, thanks!
Sent from my Galaxy Nexus using xda premium
Forgot it is 1700 (should be), that is not supported on the i9100. It can connect to tmobile due toe the 850, which is edge speed.
GSMarena says the i9100 supports 1700 only for telus (another variation of i9100 probably)
Yes, T-Mobile needs the 1700 and 2100 bands but GSM arena says it does indeed have both so I'm a bit confused.

Amaze 4g bands

Hi
i want to buy an Tmob AMAZE 4G but i'v noticed that there are 2 types of AMAZE'S with different bands :
http://www.gsmarena.com/htc_amaze_4g-4097.php
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 1700 / 2100
or
HSDPA 1700 / 1900 / 2100
HSDPA 850 / 1900 / 2100
in Israel im using the HSDPA 850 / 1900 / 2100 bands how i'll know that the device is match the bands?
regards
just look at the place you are buying from they should mention it.. ebay seller should mention it and also stores
and if you are in cellcom you only need the 2100 band.
orange and cellcom use 3g 2100 band and pelephone use 850 band
im buying 2nd hand/...
When I was in Palestine, I used my phones and they all worked on Orange. I have my Amaze box in my hand. The T-Mobile Amaze has the 850/900/1800/1900/2100 frequencies. So it will work.

Well it will certainly work to make calls, but the main issue is whether or not it will work on the 850 MHz band to use 3G and 4G. That's what I need clarified.
Looks like your question was answered. In the future, all question related threads belong in the Q&A section only. Thank You.

Compared to the Xperia S, I think battery life will be better on these phones since they use the S4 vs the S3 processor. That being said the capacity of the batteries are similar (1750-1850 mAh). We'll see how they do when they come out though.

C6833/c6806/c6802 4g lte & networks explained

I've already preordered my Sony Xperia ZU from atgsm.com
Although it's backordered right now and I have to wait another week for it to arrive, ( SUCKS because I even got FedEx 2 Day Shipping! ): )
I can POSITIVELY and SURELY CONFIRM that:
C6833 Works on all networks INCLUDING 4G LTE for T-Mobile as this uses BAND 4
C6806 Works on all networks INCLUDING 4G LTE for T-Mobile and AT&T
C6802 Works on all networks EXCLUDING 4G LTE
Hope this clears up any confusion. The International version of the Xperia ZU will work on all networks that have 4G LTE as well EXCEPT AT&T'S, presumably because it does not have the supported band. (I cannot confirm but am 99% sure) The North American (US) version will be slightly cheaper by $20-$50 depending where you order it from. The only true benefit of this (besides saving money of course) is the ability to connect to AT&T's 4G LTE network. Other than that, they are both the same. (EXLCUDING C6802 which does NOT support ANY 4G LTE speeds)
If you don't want to wait until after October 14 like me, go ahead and get the international version. Some websites have good deals and you might be able to get it at an equal price OR cheaper compared to the C6806 if you look wisely and do your research.
Personally, the international version is the way to go if you aren't on AT&T's network because if you ever go somewhere outside of the US, you can still use prepaid phone plans or such and access the internet. For such an amazing device coming with a premium price tag, I'd like to be TRULY mobile with my phone!
PLEASE stay tuned as when my Xperia ZU arrives I'll do a live video of me taking off the Anti-Shatter Film as some of you wish to do so. (Same here) I'll also post up some pictures of the cases I have and screen protectors I'll be using (SPIGEN TEMPERED GLASS COMING SEPT. 30!) and various tests (NOT the usual ones you see of benchmarks and such, but rather more interesting ones like size and everyday practical use)
If you guys have any questions just feel free to ask, we're a community here so let's see what valuable knowledge we can offer!

Correct. The C6833 has octaband LTE support. The bands on the Z Ultra (C6833) are 1, 2, 3, 4, 5, 7, 8 and 20. The big additions here are 2 and 4 which will open up the Z Ultra for broad use on major LTE networks in North America. AT&T have band 17, Verizon use band 13, Sprint use 25/27 and US Cellular operate on 12. Only T-Mobile have stayed ‘open’ on band 4. The other main carriers mentioned do also use bands 2 & 4, the unique bands allow them to lock down devices they sell to their own LTE networks, but 2 and 4 are open.

So that means you could'nt use the c6833 on At&t LTE network then.

I can confirm this to be the case. I am currently running the C6833 on ATT and an unable to get the LTE to work. I have called them and checked and they have said by not having the 700 band, that is whats keeping me from accessing their LTE network. Right now all I am getting is HSPA+ on their network and it works pretty well. It has been a PITA getting all the network settings to work all at once but I think I have it all good now, so if anyone is trying to use ATT and having problems, I might be able to help.
One question I do have is that most LTE phones that are made specifically for ATT have LTE 700mhz band 17/2100. the C6833 has the 2100 band, so my question is why cant we access the LTE network using that band since we dont have the 700mhz?

You can't use it on LTE because 2100 is Band 1. The US does not use Band 1 (2100) because Band 4 (1700+2100) uses the 2100 for its downlink, therefore it is already being occupied. Make sense? Band 1 (2100) is something one sees mostly in Europe/Asia.
AT&T uses Band 2 (1900), Band 4 (1700+2100), Band 5 (850), and Band 17 (700). The majority of their network currently runs on Band 17. Without Band 17, you will not be able to access their LTE network in most places (I can only think of 3-4 places where they are not using Band 17 due to spectrum constraints).

Normally you will NOT see a LTE logo unless yo do some time of root or customization outside o the stock Sony UI and launcher that came with the phone. (I cannot confirm but so far with my recent phones, this has always been the case.) The only real possible way of proving that you're on LTE from T-Mobile is by getting an app and clocking your internet speeds.
Regardless, if you're satisfied with the speed of your data connection and the lightspeed of the Sony ZU, there's no need to bother. (Unless of course you feel conscious of shelling out the extra 50 or so dollars.)
Rest assured, my ZU C6833 will be coming in this Friday and I myself am on T-Mobile. I've heard time and time that everyone has been able to connect to their respective 4G LTE networks with ease, and combined with the speed and finesse of the phone it's a breeze to surf the web, play games, multitask etc. I hope that you're satisfied with what you have! It would be a shame if you device was faulty! (Let's hope not!)

Not sure what's confusing. Learn what bands your carrier uses and compare them on the spec. sheet.
T-Mobile uses Band 2 (1900) and Band 4 (1700+2100 or AWS) for HSPA+ (a.k.a. 4G) and uses Band 4 (1700+2100 or AWS) for LTE (a.k.a 4G LTE).
The c6833 according to Sony supports Band 5 (850), Band 7 (900), Band 4 (1700+2100 or AWS), Band 2 (1900), and Band 1 (2100) on HSPA+ and Band I (2100), Band 2 (1900), Band 3 (1800), Band 4 (1700+2100 or AWS), Band 5 (850), Band 7 (2600), band 8 (900), and Band 20 (800) on LTE.
Therefore, the 2 HSPA+ bands and the 1 LTE band you need for T-Mobile are on the c6833. It will also work great internationally. If you have AT&T though, you will not be able to get LTE and need the c6906 model.
Thank you for the confirmation.

I have an t-mo s4 and i get lte, funny thing is i get lte speeds no logo shown or in the networks shows 4g not lte
I have the same APN settings on my c6833. I get LTE on T-Mobile in some areas (San Diego, California) but if I go somewhere there is no LTE, I get no data. It's like the phone doesn't want to switch to HSPA+ or anything else if there is no LTE. Do I need multiple APN's or does anyone know how to fix the data being either LTE or nothing?
Edit: I changed the "Bearer" to "Unspecified" instead of "LTE" and now it gets H+ but no LTE... Weird...
