First Galaxy S7 teardown reveals the liquid cooling system

First Galaxy S7 teardown reveals the liquid cooling system
It's barely been a day since the Galaxy S7 and S7 edge were announced to take on the smartphone world by storm, and the Galaxy S7 already has its very own teardown treatment, watertight chassis or not. A Russian tech blog has gotten their grubby mitts on an S7 unit, and gave the trusted heat gun a bit of work to disassemble the back panel, and expose the internals.

First off, the Galaxy S7 indeed has a liquid cooling technology inside, how cool is that? We don't know, but it is built on some intricate flat copper piping with a tiny amount of liquid housed inside that is weaved around the CPU/GPU combo to take away the heat that the new Exynos 8890 and Snapdragon 820 chipsets would generate under, say, gaming stress. Samsung put a specific emphasis on the gaming abilities of its new handsets, as the phones support the new Vulcan graphics, and it has even created a dedicated Game Launcher that will minimize notifications and other disruptions while you game. The excessive heat generated by the GPU in these scenarios will now be taken away and distributed more evenly, thus avoiding any chance of overheating, freezes or shortened motherboard lifespan.

The other interesting observation that the folks who disassembled the S7 had, is that there is only very strong and watertight adhesive gluing the rear cover to the frame, no rubber seals around, so they began wondering whether you could lose the IP68 waterproof rating if you leave the phone for a prolonged time in the heat somewhere, or if you take off the cover in a repair shop to replace the embedded battery or the screen. The other takeaway is that the power button is built on a very sturdy mechanism, and is unlikely to break easily with time, which sounds reassuring. Take a look at the first Galaxy S7 teardown below.

Samsung did say they made the s7 waterproof form the inside, over stopping it from going in,if that means anything, no idea, but that what they said?

Yeah when Samsung does it then its a like natural wonder of the world. But when the 810 phones (Z5 has DUAL heat pipes) copied this tech from PC's, they were being bashed left right and center. PA should be ashamed of their disgusting behavior.

No they were being bashed because the pos 810 was still overheating

The only thing that sucks in this phone is the exynos. Pretty much sd820 version is flawless. I hope that the phone has no 4k recording limit finally. Otherwise, I'll be greatly disappointed.

I ve seen some antutu benchmark tests where the exynos scored higher than the sd820.
But even if it had a lower score, it is still getting more than double what 2015 was scoring.
So I fail to see how it sucks.

He's a Snapdragon fan. He can't accept that he's Cpu is crap. Comparing it to the Exynos. Though 1 good point the SnapDragon is more Dev friendly.

Looks, for android muti-score is better so I do not give a crap what antutu says I more about geakbench says and that ver close single core and a killer muti
Also the m1 keeps the score on many tests

The SD800 was fast enough for me. From here on out it's all about power efficiency and I can't wait to read about which one performs better. I'm probably going to go with the G5 though so I guess it won't matter anyway.

SD has more wide developer's support. This is the reason I want SD. Otherwise, what Qcomm did last year is not forgettable.

The Exynos is more powerful. Exynos chips were always underclocked to meet same expectations to the SnapDragon variant. Or-else Exynos destroys the SnapDragon. Due to heat. Now they've used cooling system to reduce heat. They should've used an advance version and use the Exynos Soc at standard or uprated settings.

Sammy had to OC the exynos to keep up with the sd820, not the other way around. 810 was crap and exynos was amazing in 2015, but now the tables have turned. I'm not disappointed with the exynos cpu as much as I am with the crappy mali gpu that comes with it. Andreno has always been superior. That's the problem.

Exynos is actually underclocked LOL. Exynos 7420 was 772 MHz on GPU, 8890 is just 650 MHz.

Talk to me again when proper tests are done. I'm pretty sure both will be pretty much equal.

Underclocked but probably bigger cores.

It should be underclocked with 12 cores! I like this approach, though. Not sure about Adreno's architecture either.

Wait for the real proper tests by reputed sites who know what they are doing in field( like anandtech or tomshardware), before coming to conclusion.

Currently it looks like Exynos has 20% faster CPU and 10% slower GPU. It may change(for better or worse) with final software/hardware. Also keep into account that mali and powerVR are usually faster in real life games than adreno GPUs.

What I wonder is if those websites will get the phone before launch. Basically, are we going to see proper tests before launch date?

I don't think so. Anandtech will release the review around early-mid April. They take their time but the end result is worth it. i prefer a late review which I can trust over an early half-baked one.

Damn.. I've been waiting for S7 to come out. But I think I was hoping for something slightly better (mostly in the camera department - still no info w.r.t. slow motion capabilities). Especially to go for a pre-order buy.

Nonetheless, I don't see myself waiting for iphone 7 (which is unlikely to have a huge improvement camera wise). Decisions, decisions.

True, but the only thing I don't like about Anandtech is their focus on Javascripts targeting single core and/or browser optimized performance, where they usually compare Chrome (not very Javascript optimized) vs Safari on iOS to draw conclusions. When in reality, the browser optimizations are doing most of the work. See Chrome vs Samsung stock browser (which they even acknowledges) showing over a factor 2 difference, or their 6 Plus results from their review, vs the 6 Plus results at the time of the 6S review, with up to 50% improvement using an updated Safari on the same SoC...

In other words, apples vs oranges, when insisting Chrome on Android tells us much about SoC performance.

You can't ignore that. Javascript is an important performance metric. I agree it doesn't necessarily compare hardware as software plays a huge part, but it shows how good your browsing will be. What good is a monstrous CPU if it lags while browsing?

Instead, google must fix chrome. I can't believe how bad chrome is compared to safari.

Anandtech tests geekbench, PCmark and basemark too. All of those being related to absolute performance. So they don't JUST test javascript.

At least they don't use Antutu LOL.

Why does the Exynos suck? It score 131,000 on Antutu, based on honest testing by other parties and not PA's testing where the phone is obviously in power save mode or something.

Actually that wasn't anything impressive. My iPhone 6S+ scores 133813. I know partly is thanks to lower resolution but it is a 5 months old phone already. The SD820 scores about there as well.

For me I would prefer to get the SD820. I want custom roms, kernels and more mods. I don't want to be stuck to Samsung rom again after the s6 terrible ram management. Even if SD820 might be weaker but it is worth it.

26. S.R.K. (banned) (Posts: 678; Member since: 11 Feb 2016)


Yes it did. The Z3+ and Z5. Oems are asking soc makers to make their chips more efficient, instead them using liquid cool based pipes to reduce heat, and also using lower Mah batteries. Stupid dumbass Oems.

It was on the Z3 first, along with Dragontrail glass instead of Gorilla glass, to reduce heat.

True. I am happy more and more Android manufacturers are treating thermal dissipation seriously. Hopefully we gets lesser and lesser thermal throttling.

There was a thread about this where the z3 used a different variation than what the 950 used, and not entirely comparable in terms of 'liquid'.

59. xondk (Posts: 1203; Member since: 25 Mar 2014)


That just is not right, phase cooling is sort of liquid cooling, taking advantage of the fact that more heat can be absorbed when switching between liquid/gas and it is in a lot of high end graphic cards what spread the head to the main headsink, meaning it is highly effective...
