Sony Xperia Z5 Premium leaked teardown photo reveals dual heat pipes and thermal paste

Most of you guys have probably been introduced by now to the Sony Xperia Z5 Premium, the world's first smartphone with a 4K display. Although our quick hands-on time with the Sony Xperia Z5 Premium was enough to verify that the smartphone really comes with a breathtaking display, there are still many reasons why we think that the industry doesn't need a 4K smartphone just yet. One of these reasons is that current-generation chipsets already have a tough time dealing with QHD displays and that the extra stress on the chipset will lead to increased temperatures and sluggish performance due to thermal throttling.

Since the Sony Xperia Z5 Premium comes with a Qualcomm Snapdragon 810 chipset, a mobile SoC that's been very often criticized for its thermal performance, many are probably wondering if Sony was able to keep the overheating issues in check without limiting the performance of the chipset too much. While that's still to be discovered when the final units get to our testing lab, a new photo leaked online today allegedly revealing the measures that Sony had to come up with in order to keep the Snapdragon 810 overheating issues under as much control as possible. Take a look:

If this image turns out to be the real deal, then Sony did its best to ensure that the heat coming from the Snapdragon 810 is dissipated as efficiently as possible. Aside from integrating a pair of heat pipes, it looks like Sony has also applied some thermal paste right over the chipset. As the name suggests, thermal paste is a viscous substance that can be applied over the CPU to help with the heat dissipation. Thermal paste is a vital thermal control ingredient as far as desktop-class CPUs are concerned, but we've never seen it applied on smartphone SoCs until now.

Unfortunately, the real question - does the Sony Xperia Z5 Premium overheat to a greater extent compared to other high-end smartphones? - remains unanswered for now. It will be interesting to see just how efficient the dual heat pipes - thermal paste combo turns out to be, but that cannot be analyzed until the Sony Xperia Z5 Premium is officially launched.

pitty on all companies (and us also) that they dont have any choice except 810. Why Qual Comm is not moving to 14nm for sd 810? why they are keep doing the same thing and keep getting the same result. It is very sad that there is no other option is this world.

Mediatek Helios x10 and kirin. There are choices, they just believe that there's hope for the 810 and it's good for consumers because we can have all of them in different products.

kirin is for huawei only, bro and hello X10 is a midranger

Why would they move to 14nm process for a chip that came out last year? The SD 820 IS using the 14nm process: Unfortunately, it's not really out yet.

Same result? did you test the phone? So you see the future? Do you have a SD810 device? do its make you trouble? I am just curious to understand as i personally use the M9 and love it. No slow down ever the phone become less hot to the touch compared to the S6 after a few hours of gaming ( the whole phone get a bit warm but the S6 there is a zone in the back thats i am afraid will melt my case lol ) I also never had 1 M9 come back for overheating problem but lots of S6 edge ( no S6 ) Sure benchmark benchmark and benchmark are better on S6 so are benchmark making you live? Also did you know S6 and note 5 are limited to 5 min of 4k movie before its turn itself off? Samsung put a limit because if you do many 5 min 4k video in a row you will see the camera app will close because of overheating. I can easily do 10 min or more on my HTC M9 but yeah if i keep on doing it non stop its eventually close the app for heating as well. Same for the Z3 its can easily do 10 min or more but again dont repeat it in a loop or its will overheat. Never forget thats company with lots of resources have more power to make ppl say thing they want. Thats called propaganda.

it is useless to argue with a delusional freak. I have used Lg G flex, M9, G4, Z4 for your information. Yes, I see the future and at the moment I am seeing the future of one moron whoes PA profile name sound like moron and he is a delusional freak. His future is this that he will remain delusional about sd810, HTC and Z series even numerous reports will suggest otherwise. He will keep considering geniun reports as propaganda. He will keep talk about S6 overheating, but still he will not be able to sell any HTC M9 on his counter in the store where he work. Thats his future, save my comment and just watch getting it come true

Blah blah blah :D No proofs as usual. You must be a crazy qualcomm fanboy or even its marketing specialist.

Interesting. The Z3+/4 certainly didn't have this. We'll see soon I guess.

Jesus Christ, Qualcomm sure laid an egg with the 810. I wouldn't even consider a phone based on that SoC. Good thing it looks like they got it figured out with the 820

6. MSi_GS70 unregistered

Exactly .. I really do not understand that manuf. know months, that 810 is bad and they still keeping implementing it.. why ? Why?

My guess is because they've been working with Qualcomm hardware for the past few years they've become accustomed to coding for it, should they have gone with Exynos there would definitely be a lot more bugs that would have need addressing. Samsung can get away with that because Exynos is their own product so they know it better.

Ram issues with the Exynos too.

thats with the Software i.e Touchwiz

Nope it as nothing to do with the software and touch wiz or ram problem, it's just a system setting that can easy be changed if you root the phone, Samsung are doing it to keep the phone super fast and iPhone like when running a vm, so after 7 apps open they start to close, I do think they need to add an easy setting that says if you click this your battery will drain and your phone will lag but you be able to open 14+ apps

Maybe because its not as bad as some try to make it? Wake up dude!

The same with exynos in their early models. Those first meizu phones really can burn your palm.

been using the M9 since its came out. Not a single problem with it. So too bad for you.

ok, we accept that HTC M9 is used as a refrigerator to make ice and also used as an AC for cooling buildings. I hope you are happy now and will stop your desperation.

they're really going all out with that thermal paste...

Even pc gaming riggers use thermal paste and large heat sinks in their overclocked cpus. If the thermal paste works then why not use it? I think it's a simple yet practical idea if that's the only problem 810 encounter.

Higher clock higher performance mean worse battery life..but I guess thats still better than phone throttling all the time.

I will probably still buy one, but had they done this internal design and used an aluminum body for superior heat transfer, this phone could have been beastly.

Props to Sony for trying to deal with Qualcomms disaster chipset. Qualcomm needs to be sued for releasing a product to market that simply isnt' fit for purpose.

ppl who say propaganda and exagerate reality should be sue by Qualcomms. I love my M9 never had any issue with it and no app ever closed for overheating beside my camera after doing about an hours of 4k movie in a row .

and you shoud be sued by my poop for being look a like

The 810 was a bit rushed to market but that was due to pressure from OEMs and their 12 month flagship cycles. QC just said f**k it and concentrated all there time in the 820.

PA, when will analyze Xperia Z5 Compact?

PA hates Sony. They'll just bash the Z5.
