Same here, the only HW problem I have had is when I got my Z2 at launch and the backplate was a bit loose, turned it in and they reglued it and returned it to me within a week and then it was perfect until I sold it off before I bought my Z3+ which feels like a solid piece of metal and glass!
[Xperia Z4/Z3+ General] miker71:
OK back to overheating discussion - I wanted to see how long the camera app would record 1080P HD video to see how it compared with my Z2. I record onto ExFAT microSD so I know it's not filesystem limitations that might otherwise cause issues.

My Z2 would record ~35 mins video before camera shutdown.

My Z3+ can only record ~9 mins before camera shutdown.

I'm hoping I can work around the issue when I need to by using 'A Better Camera' which on the Z2 allowed me to record for 1 hour+ (I sometimes do video interviews that last about an hour).

This suggests to me that the overheating issue still exists for specific tasks. However day-to-day casual use it's not a problem at all for me.

The overall quality of the results from the camera on the Z line are what make me stick with it, plus, it records an adequate stereo sound stage (I know most Androids do but I am a switcher from iPhone which is still mono after all this time).

I have also noticed some UI/UX stutters on the Z3+ but not enough to be annoying - but the Z2 on 5.1.1 was buttery smooth all the time.

Casual gaming 'Respawnables' the phone gets a little warm but hardly noticeable. Other stuff like Words and Jetpack Joyride are so casual the phone doesn't break a sweat.

I do think Sony needs to fix the issue once and for all, or, admit it cannot be fixed but must be managed by the user.
[Xperia Z4/Z3+ General] JR5968:
Same issue here

1080 p 30 lasts less than 15 minutes

Average 8-9 minutes

I was dissatisfied with the phone so sent it back for a repair with Sony
[Xperia Z4/Z3+ General] miker71:
Ok so this morning I let 'A Better Camera' do a continuous take on my Z3+ - it only managed a little over 14 minutes which is pretty poor. Phone didn't even seem to get that hot (sure it got warm to touch).

How this phone won the EISA award is anyone's guess!

https://www.eisa.eu/awards/mobile-devices/58/european-multimedia-smartphone-2015-2016.html

I do still really like the phone though, it's just a pity its video functions are not more robust. Maybe with 5.1.1 .... ?
[Xperia Z4/Z3+ General] schecter7:
Temp. threshold for camera app is too tight (55C). If the CPU is at ~50C after using bunch of other apps, I'd not bother to record if I need more than 3/4 minutes. Before long recording, I just let the phone cool down for 2/3 minutes till the temp drops to the low 30s. It can easily do 20 minutes of 1080p afterwards.
[Xperia Z4/Z3+ General] JR5968:
My one does max 14 mins after a long cool down , if I have used the phone for browsing just before 1080p 30 fps stops within 5,6 minutes

if it cools down for 2,3 minutes the maximum it can do was 9 minutes

So it has been sent to Sony SBE and waiting to receive it back after repair
[Xperia Z4/Z3+ General] miker71:
This morning I tried one long take with video using Google Camera app from https://play.google.com/store/apps/details?id=com.google.android.GoogleCamera

Although it saves to internal memory, the fact the Z3+ has 32GB internal (about 22GB free on my device with my apps and games installed) means it's not a problem like it was on my Z2.

Result: I successfully recorded 58 minutes before I pressed the stop button. This encourages me that this camera app will remain stable when recording my video interviews. The resulting file was 7.3GB so the only thing I have to manage is to check I have 8GB free on my device internal memory.

The Z3+ did get warm, but not as hot as when using 4K or AR etc.

The autofocus, AWB, AE on the Google Camera are fine for my purposes - all re-calibrate very quickly easily on-par with my old iPhone 6 Plus.

So ... phew ... another Android another workaround implemented :)

Really hope Sony can fix thermals with the native camera app though cos I do really like it - but obviously limited to short takes.
[Xperia Z4/Z3+ General] JR5968:
Got my phone back from Sony today

It seems to perform much better, doesn't heat up like before

Yes it gets warm but all phones do......
[Xperia Z4/Z3+ General] sstanton86:
My Z3+ is less than 24hrs old. Haven't really felt this heat thing as much as some people have suggested. Been browsing the Web for a while and it's a bit warm but nothing out of the ordinary.

P.s best phone I've used and I've used them all!
[Xperia Z4/Z3+ General] illetyus:
My average temps are 35-42. What are yours? I am using SYSTEM INFO DROID app..
[Xperia Z4/Z3+ General] hasona:
Those are pretty much average temps on all Z phones. So you're good :)
[Xperia Z4/Z3+ General] illetyus:
When should i get worried? I have seen 47 degrees celcius at most.
[Xperia Z4/Z3+ General] hasona:
47 on which temp sensor? On the battery temp sensor I have never crossed 41 C on my Z3+ which is mostly when I am charging my phone and using Chrome at the same time otherwise it never crosses 40. My Z2 used to hover around 43-44 on battery temp when charging and using it which seriously feels a lot hotter than 40-41
[Xperia Z4/Z3+ General] illetyus:
What sensor should i use? What app do you use to get temperatures? I use cpu-z
[Xperia Z4/Z3+ General] hasona:
In CPU-Z you have a lot of temp sensors, usually the most important ones are the battery sensor and the cpu sensor follow my picture and give me your results
[Xperia Z4/Z3+ General] markdave.medina:
Cannot post yet external image links, but my msm_therm hovers around 36-40 °C and battery gives 32-37 °C on normal usage. When I do medium browsing and games, it shoots up to 40-45 °C. Is this ok or I am encountering overheating?
[Xperia Z4/Z3+ General] schecter7:
It's perfectly fine. I bet you'd see higher numbers on your older phone.
[Xperia Z4/Z3+ General] hasona:
Thats totally fine and alright, the concern i more when you start hovering around 55-60C on a longer timeframe then its cause of concern
[Xperia Z4/Z3+ General] Dathrex:
Just watch this video guys , I recorded it... Z4 turns into 400 bucks smartphone after 2-3 mins of gaming (When it gets hot) .

Epic fail Sony...

[YOUTUBE]Fb2GlgZx8a0[/YOUTUBE]
[Xperia Z4/Z3+ General] zabi1994:
Well, PPSSPP was never a fully optimized PSP port anyway.. Performance drop was always an issue with it..
[Xperia Z4/Z3+ General] Dathrex:
and what about other games?

I installed Reckless Racing 3 and got 12-15 fps from 30 after phone got hot
[Xperia Z4/Z3+ General] zabi1994:
Well, that is exactly what is expected right ?? Phone gets hot, drop in performance.. All devices do that.. Look, the phone may still has its overheating issue.. If the phone gets really hot, then I guess you've pushed it a little too far.. Just give it a break when its too hot.. We all know the overheating issue is there in certain cases, there is no point bringing it up anymore..
[Xperia Z4/Z3+ General] Dathrex:
And Companies call such phones flagships? I haven't had high end smartphone until now and now I see that high end smartphone is nothing but pure marketing....
[Xperia Z4/Z3+ General] illetyus:
If you are comparing devices just by gaming, then buy Nvidia Shield. It has better gaming performance over ALL mobile phones.
[Xperia Z4/Z3+ General] LitoNi:
Lol i can't believe there are people out there who would play intense games on a smartphone haha, kids. If you got the money go build a desktop and get a gtx 980. Sorry i just believe mobile games are pathetic.
[Xperia Z4/Z3+ General] zabi1994:
Not a single flagship smartphone in the world is perfect man.. Always a downside somewhere.. You just got to find the right one for you.. If you can't settle with this phone due to its weaknesses mainly overheating, then the best thing for you is to change to a new one, one with "less" weaknesses.. That's about it.. If you're not in the market for a new smartphone any time soon, then you probably made a mistake buying this phone.. Just settle with it and get over it already..
[Xperia Z4/Z3+ General] Dathrex:
Yea, I demand multitasking and performance from the phone. I'm not interested in instagram,texting and such things.I had mid end phone for that. Well, I am very disappointed finding out the truth - 800 bucks for mobile radiator :/

Litoni, I have high eng gaming PC, just wanted to transform it into the phone. I'm very enthusiastic about this case.
[Xperia Z4/Z3+ General] [NUMINIT]:
Weirdly, it seems to be very random with my unit. Some days I can play, say, World of Tanks Blitz for half an hour with no hiccups whatsoever, other days it's five minutes and my hand burns and fps drops from the usual 40-50 to under 20. I haven't noticed any major variables in the way I use the phone so far.
[Xperia Z4/Z3+ General] propov:
With the last update 28.0.A.8.251 the heating is reduced.Before i think to sell the phone because overheting.Now I will keep them.

And for the gamers. Open the sim door to help cooling proces. It works for me from first Z.
[Xperia Z4/Z3+ General] illetyus:
Actually placing aleminium folio helps. I used to record 4K at most 10 minutes. Last day i was able to record for 14 minutes. It is %40 more.
[Xperia Z4/Z3+ General] Sunjay140:
Is the census that the Z3+ drops frames quickly when gaming? That sucks, I mainly play emulators and PPSSPP performance is important for me.
[Xperia Z4/Z3+ General] Dathrex:
Same here bro. Actually I placed Aluminium folio and phone gets hot a bit late compared to stock. The only hope for me now is root to set some badass governror or at least just set it to performance
[Xperia Z4/Z3+ General] addicted1900:
I think setting the governor to performance will throttle your device earlier... Maybe there is a way to adjust the thermal throttling. This would be helpful for your goal.

Was playing that Tomb Raider Relic Run, after about 40mins the device was heating up and the game became really slow and laggy.
[Xperia Z4/Z3+ General] DryKillLogic:
It's a shame we have to look for workarounds with a so-called "flagship".
[Xperia Z4/Z3+ General] victorgti:
Marshmalow Z3+

It could resolve the heating issue the new version Marshmallow?

Sony has announced about the imminent and direct update of the Z3+

:confused::o:laugh:
[Xperia Z4/Z3+ General] LucifersDemon:
Idk about that, tbh. Sony seem to have *abandoned the Z3+. *Maybe that's exaggerating, tho I am not under the impression that they'll do anything else for it.
[Xperia Z4/Z3+ General] yuunanase:
I had been a frustrating z3+ user since day 1. The device was not VERY hot, but warm. The problem is the throttling, which causes everything so slow down so much, that I sometimes have to force restart the device. Recently, moving to z5, I found that the temperature to be more or less the same, but the z5 does not throttle! And this is what the z3+ suppose to be!

Or this is what I though.

Until I factory resetted my z3+. I found the performance was exactly the same as z5! It might have been the background apps, I wondered, so I installed all the apps I used on my z3+, but the device remained consistent. No throttling, launching apps was lightening quick, perfect camera, etc.

Ok, not exactly the same, especially the camera: got 22min 4k video on z5, compared to 5min on z3+, but other than that, I am very happy with z3+
[Xperia Z4/Z3+ General] victorgti:
I have the z3+ from two month ago and "HEATING IS TERRIBLE" if per example it is charging, with brightness 100% and browsing, the temperature raises until the brightness decreases for protection until the minimum brightness, the back of the phone almost burn.

I repaired the phone with Pc Companion after Update to 28.0.A.8.266

I need help.

Many Thanks
[Xperia Z4/Z3+ General] mark_q07:
Maybe, a factory reset may help lessen the heating issue. It worked on other users; it may also address your concern. :)
[Xperia Z4/Z3+ General] amit694:
Hey friend r u sure that its not overheating as mentioned on internet? Can you please show me a video of using mobile camera for normal photo shoot to know for how much time it can work without warning message. And also while normal 3g browsing.
[Xperia Z4/Z3+ General] addicted1900:
Hi,

I'm sorry but my z3+ got stolen and I purchased a z5 compact so i cannot post a Video. In fact, till i lost the Phone i never encoutered any overheating issues. Last year I took many Photos with the Phone in my summerholidays where ambient temperatures where about 30-40°C and the Camera never stopped working. I didn't even got the "shut down- warning".

I'll have to add, that I am not a mobile Gamer nor I tested the 4k Video function.
[Xperia Z4/Z3+ General] ChiDi9901:
I have just got my Z3+ and after unboxing it I have immediately updated it to Android 6.0. I really hope that I will never experience the "overheating" issue. I'll see then. It should be optimized software wise by then.
[Xperia Z4/Z3+ General] farrokh19:
Some feedback about overheating after these two days? Because I really want to buy this beautiful device, I have found the copper one at 300 €, a lower price that Z3 one. It's worth buying it ?

Thanks
[Xperia Z4/Z3+ General] ChiDi9901:
Here is my honest response: when I do a bit of gaming on this phone - I've only played Ingress (see Play Store for description if you don't know what it is) and an HTML5 online game on What's New so far - it did get pretty warm. I noticed that the most warmth came from the upper half of the phone. But I didn't encounter apps crashing nor the softwares starting to slow down, so no lags if you want to say it like that.

I also played around with the camera a bit and it also got warm. Now, just to let you know, I haven't shot 4K videos nor any videos yet and have only taken pictures. Luckily, on Android Marshmallow I didn't receive the notice that the camera was going to close because of the device getting too warm. So let's say no problem there.

After getting warm the device did cool down again and, as I have mentioned above, the device didn't noticeably slow down or stutter.

If you can get this device for 300€, there is no problem going for it. I got mine for 380€ and I don't regret it. I bought it because I didn't enjoy my previous phone (the Zenfone 2 with 4GB...) so I am much happier now. Yes, it's a gorgeous looking device and it's really light.

If you expect a fuller opinion of this phone then I am sorry, two days usage is not enough for me to say how good this device is. But my first impression is positive.

[Xperia Z4/Z3+ General] farrokh19:
These are good news and I understand that you can give just your first impression after two days. So probably with MM Sony solved partially the heat problem. Anyway if it's only warm or hot it's not a problem, the real problems were lags and camera crash but by yours and others opinion seems that they are disappeared.

Just a last question. When you will try 4k video, could you say me if you can some minutes of video without advice and crash? I'm not interested to do 30 min of 4k video but just 5 more or less.

Thanks again
[Xperia Z4/Z3+ General] ChiDi9901:
OK, I did my first 4K test just now for fun. Sadly I received a notice about high temperature. Then, somehow not so unexpected, when I reached 4 min. and 54 sec. the camera closed itself. Conclusion, you can't shoot 4K tutorials videos with it for example.

One thing I haven't mentioned before is that after unboxing the device I updated it immediately via OTA and not via PC companion or any method using a PC. So maybe it would be better to update through PC to have a clean flash of the firmware. So there is that. If you really need a phone that can record 4K properly, then this phone is not really recommended.

Cheers!

Hi man !

I'm looking to return my phone (Zenfone 2 ) and probably buy this one. Is it an upgrade?
[Xperia Z4/Z3+ General] Robert-:
Thanks for the awesome post!

Well,tbh the only negative that I kinda care about is the overheating while recording. But ,let's be fair : The ZF2 can't even record 4k and the camera is ..well..ok?

How is the actual battery life. Worse or the same?Better?

Thanks !
[Xperia Z4/Z3+ General] ChiDi9901:
It's somehow the same. Depends on the daily usage and if you do intensive tasks. If you're a heavy user, both phones will not last a complete day at all. If you are a user that only checks emails or messages or browses the web now and then, it should be okay (for one day-ish). If you don't use your device at all then the battery drop rate seems little. Be aware, the warmer the processor gets the faster is the battery drain rate and that's sadly the weak point of the Z3+ (for now?). If the device stays cool then yeah, you get the point. I never had a phone where its battery life satisfies me, only the Z3 tablet does a great job haha. Also in the next Android 6 update, Sony will add back stamina mode (yes, it's been removed in the recent version of Android 6 because of Google's 'Doze') which should improve battery life hopefully.

Mmh,i don't know. When i had the phone running (had to sent it back after 1 week because i couldn't power the ZF2 up anymore) I had like 5hr SOT..

I'm mainly using my phone for

Internet

Music

20-30 mins of gaming/day.

:confused:
[Xperia Z4/Z3+ General] Aniruddha10:
Hey everyone. I'm thinking about buying this phone and coming from a sony xperia zr it's definitely an upgrade. I've been hearing that the new updates have resulted in better usage of the 810 processor and less overheating but I've also heard there hasn't been much change. Would really appreciate anyone's feedback on their experience of stock Marshmallow.

Btw, if this isn't the right place to ask I apologise and will post my question elsewhere.
[Xperia Z4/Z3+ General] diemadedrei:
You will hear different things from different people. Some didn't have problems in the first place, some, like me, had problems that are much improved since marshmallow and some still have problems now. But the overall situation seems much improved.
[Xperia Z4/Z3+ General] kongha:
I would also like to know.

What I can see is that the issue is still there.
[Xperia Z4/Z3+ General] sxtester:
Definitely, there were severe overheating issues up and including Android 5.0.2 (.266) and I wasn't really too happy with the phone.

But now, after upgrading to MM (installed .185 and did a full reset while flashing with Androxyde Flashtool) the heat issue is completely(!) gone. Even better,... it's fast as hell. Yes, there are still some (minor to me) glitches in that FW, but I'm sure it will receive 6.0.1 soon enough.

So happy that I bought the phone for a heavy discount recently :p
[Xperia Z4/Z3+ General] kongha:
Got the sony z3+ yesterday (and wow! such a nice phone). Ive the latest softwareupdate 32.1.A.1.185 and tried 4k video recording.

After 5 minutes inside an office I got a warning about temperature and after 8 minutes of recording I did turn off the recording. No app crash but the top part of the phone become warm in a not so comfort way.

Edit: 15 minutes of Asphalt 8 outside in the sun. No issues :)
[Xperia Z4/Z3+ General] ravichandrabr:
Can u pls confirm how closely it takes macro shots??

Can u pls review camera specially close-up shots??

Am thinking to buy it
[Xperia Z4/Z3+ General] kongha:
if you can find the phone with a good price. Buy it. Its the best Ive used :)

I dont know how to review macro images. I would say it captures what I photo quite well. If you can, please link to how to make a macro image for a review (what object I should take and such :))

Here is an example of an orchide at my workplace, dunno if its what you ask for:

Hey all

Just bought my new Z3+ and I have to be honest, I agree with the OP, yes it gets really warm to the touch on the odd occasion, but not the disasterous symptoms Ive read about... No app crashes, stutters, lock ups or battery drain, just gets hot when using the camera app and in some games, I almost didnt buy this phone because of some "forecasts of Doom" ive read...

I have yet to fully test it, but i bought this phone for the great Colour reproduction and White balance in the camera images (I find the cameras best at 8mpx, less processing, ... in fact images are all "mushy" at 15.5 and even better than the Faulty camera of the Z5 ) and the Walkman music player through headphones is stunning (better than my G4 and any Apple ipod/iphone).

Im really happy with it, and its nice to read a thread that doesnt just point out a devices faults all the time..

Nice :)

I bought mine a week ago - cooper colour! It's really great phone actually! I only get heat issues when surfing with 4g with high outside temerature! So I am good! About video, well I never had to record a video more than 4 minutes..!

I am very pleased with my purchase, hope Sony will keep supporting it :cool:
[Xperia Z4/Z3+ General] r_diaz13:
Agree, gets a little warm compared to my previous phone (2013 Moto X) but overLl is not a huge deal. Battery is a bit iffy here and there but gets me through an entire day without needing to plug in before bed time. I bought for a steal in amazon ($307) which is absurd given the quality. Never had a Sony phone but the design and quality feel amazing. Love the UI and everything it brings to the table.

In my opinion Moto's conceptual featured are ahead of the game in the smart phone Industry but the design of this phone surpasses the new Moto X. Not a fan of jigger and bigger phones and I think Sony did a tremendous job with the Z.
[Xperia Z4/Z3+ General] kongha:
anyway to see the batchnumber of the phone?
[Xperia Z4/Z3+ General] NightOrchid:
My old M9 got hotter than this, even after HTCs update, but I do like SONYs UI, I know many dislike it... but SONY have some great apps... I just wish theyd create better speakers, but I think its the waterproof membrane that prevents them from being their best, but the headphone amp sure makes up for it.. :) At least SONY have finally increased the Ringtone volume under MM and theyre nice and loud

Would you rather have better speakers or waterproofing?.

Tis a great device though
[Xperia Z4/Z3+ General] mugglearchitect:
Hi! So all in all, I should not be afraid of buying this device? Should I go for it?
[Xperia Z4/Z3+ General] AntwnisGr:

[Xperia Z4/Z3+ General] mugglearchitect:
Thanks! I was originally wanting a Z5 but it's more expensive, so I decided to have Z3 instead. But then I remembered there's a Z4 (Z3+)! I hope I'll love the device :)
[Xperia Z4/Z3+ General] akashsgpgi:
if you are heavy gamer then just stay from this phone. Otherwise I have no reason to not recommend this phone.
[Xperia Z4/Z3+ General] mugglearchitect:
I'm not. Though I play sometimes when I'm bored. I mostly do facebook, watch videos (a lot), reading. Is this kind of activity incur too much heat, you think?

I'm leaning towards this phone, but still thinking of Z5. The arguable better camera, the new design, two heat pipes. Those are basically what I like about Z5 over this phone. But again, I'll save around $110 if I'll go for the Z3+
[Xperia Z4/Z3+ General] akashsgpgi:
Then you'll be fine. The phone does get a little hot sometimes but there will be no lag in general use and applications.

Just to let you know z3+ and z5 have have nearly identical kernel and software. Sure z5 would have better thermal control but from what I have heard that even z5 gets really after heavy usage and starts to lag just like z3+. The only difference is that z3+ lags just after 5 mins of gaming and z5 would lag after 15 mins. The snapdragon 810 is too much for small devices like smartphones. Surely the smartphone manufacturers were not ready to handle such a power hungry chip.
