Revised Qualcomm Snapdragon 810 no longer overheats? Video of a Sony Z3+ prototype begs to differ

Revised Qualcomm Snapdragon 810 no longer overheats? Video of a Sony Z3+ prototype begs to differ
With more smartphone manufacturers turning to the Snapdragon 810 SoC, the first comments from the peanut gallery are usually along the lines of  "Boy, is that phone going to be hot," or "The only thing that phone will be good for is playing hot potato." But some manufacturers have been working on ways to prevent the Snapdragon 810 from overheating without resorting to throttling the chip's performance. The latter is what HTC was forced to do with the HTC One M9.

While Xiaomi came up with its own fix for the problem when it used the chip on the Xiaomi Mi Note Pro, Sony is using the Snapdragon 810 v. 2.1 for the Sony Xperia Z3+ and Sony Xperia Z4 Tablet. Reportedly, this version of the Snapdragon 810 SoC does a better job at managing the heat generated by the chip. The revised version of the chip was discovered in the source code for the Xperia Z3+ and Xperia Z4 Tablet, published by Sony. The code refers to the MSM8994-v2.1. For those unaware, the MSM8994 is the model number for the Snapdragon 810.

The Snapdragon 810 is also expected to be powering the Microsoft Lumia 940XL and the third-generation Motorola Moto X, as well as other handsets. We have to assume that the new version of the chip will be employed on these models or otherwise the manufacturers would worry about the prospects of consumers complaining about having to hold a hot device.

If the revised version of the Snapdragon 810 SoC doesn't overheat, Qualcomm is hoping that word spreads just as fast as the original reports about the overheating did. However, a video has surfaced showing that overheating issues are still present on the Sony Xperia Z3+. A couple of warnings pop up relating to high temperatures and you can see this for yourself by clicking on the video below. Keep in mind that the Xperia Z3+ in the video is a prototype using pre-release software which could be changed by the time the phone is released.

TIL that your flash could also be forcefully disabled during camera use while the phone waits to cool down.

Not a single M9 user came back to my store saying the phone overheats.. PA need to stop the propaganda! PS: i had 3 customer with S6/S6 edge thats had overheating issues on another hand...

I have a feeling PA hates sony, and htc. Specially sony. Sammy and Ip, not do much. But I might be wrong.

Don't know about that, they definitely have Apple favoritism but after seeing HTC and Sony screw up again and again, I think they actually are run by incompetent twats.

Because after an update it got very limited clock speeds.

They didn't say that the m9 overheats, they said that HTC throttled the chip specifically so that it *wouldn't* overheat. Facts are not propaganda just because you don't want to hear it. I get it, you don't like Samsung. But there's really no need to bring them up in half of your posts. Especially when they have nothing to do with the article by any stretch of the imagination. All you seem to do is read whatever the problem is listed in any given article, claim Samsung is suffering from whatever the flavor of the day is and deny that it affects anyone else but them. It's not like your personal crusade is going to have any effect on them in the real world anyway, so I don't see the point. Which is a shame, because the s6 does have some issues but when you try to claim that it suffers from everything under the Sun, you take away from that legitimacy.

Oe m9 is throttled to much, it won't overheat for sure.Check out single core and multicore score of htc one m9 and lg g4, even with 2 less A57 cores, g4 performs better.

It's because the M9 is software-throttled, making it slower than qualcomm's 2014 SOCs. At least with the S6, even though it's warm, you're still getting more or less the same performance (which trumps the SD810 when warm). Not a Samsung or HTC fan, hah.

I have played with galaxy S6 for few mins and it heats up very quick...and more than my oneplus.

Btw, even tho im using Sony, Z2 and Z3 are overheating with camera. The camera app is to blame not the cpu.

Overheating, in term of a CPU/GPU/SoC, can be understood as - Too hot, or - The temp reaches the thermal limit and has to be throttled down (agressively) THe second case is of HTC One M9. Many tests has shown that One M9 is slower than One M8, and play games more laggy than One M8

That's because they fixed the issue, problem is that the device doesn't perform at its full potential. It's not bad as articles claim it's still 15% more powerful than the M8, but considering its change to 64 bit and using higher end cores it should have been even more powerful (apparently the device runs mostly on A53 cores rather than the A57 to prevent this overheating).

Same cry baby attitude here also Marorun , Exactly the same comments even in the post where they mentioned abt htc plummeting . Did you buy a M9 and now stuck with it as no one is going to buy it off you for a decent price . HTC m9 sucks , live with it. Sony should have gone for exynos instead of SD810.

You do realize that exynos is likely a Samsung exclusive, so I don't understand why people keep saying they should have used exynos when exynos has only ever been used on Samsung devices.

The clock speed as been under clocked big time on the m9 and why it does not over heat, but is why the lg G4 easy opens apps faster than the m9 and the m9 even as more lag

Too bad, even android authority too said the z4/3+ does overheat. Even Japanese carrier warned about the overheating issue. So get over it, sd810 is crap.

The user most probably used the camera to do 4k video... my S6 clients thats had overheat issues had those after filming 4k videos.

Sorry to say mate but when the s6 came out without any updates the only thing that make the phone overheat is the bug in the theme Maganer and when you install themes not when you use the themes, only when you install loads of them, when you done if you gave time for it to stop overheating then the theme work without problems, why there was reports of laggin when using themes by review like on pocketnow I.e. They installed them and then started using them

Not Good, Sony needs to address this quickly why go with the snapdragon 810???? Why not Just bite the bullet and use Samsung's SoC? Whats the big deal Samsung users Sony camera sensors? Don't let your flagship suffer because Qualcomm was to slow to get to 64 bit architecture and rushed the 810 to market to catch up. Unless Samsung just can't meet demand of its's SoC for its own mobile devices and has no spare capacity ( Think I answered my own question) .

Easy, no sd card support and you have to use ufs 2.0 on the bus of the 7420

Oh dear, the Snapdragon 810 strikes again. If HTC and Xiaomi couldn't keep the chip cool, what made you think Sony would be able to? Especially with the Z3+ being IP68, meaning tightly sealed. Good thing is that you can always dip it in ice cold water if it heats up and it will be fine. Qualcomm need to get that Snapdragon 820 out ASAP.

It can be cooled by water, but not by ice cold one. Temperature shock would probably cause the glass to shatter. Putting it under the tap or in a glass of water at room temperature should be fine.

Previous Sony flagships (Z2 or Z3) had similar heating problems with SD801 while running camera app. He should have run Gfxbench and measure the temperature.

Its weird to think Sony skipped the Snapdragon 805, which just so happens to be the coolest running chip of the whole S8xx range. My Note 4 barely heats up and you do not hear much about the Nexus 6 or Motorola Moto Maxx heating up either, all 3 based on the 805. :)

Only time my Droid Turbo (QSd 805) heats up just a little is when i "turbo" charge it, otherwise no heat issues at all.

Oh dear, they should stop wasting money on this lemon. Just fix 808 with Adreno 430 and you got a nice balance. I blame the oem's that continue to buy this cursed SoC.

This would be a better solution, the CPU arrangement on Snapdragon 808 work fine, it's GPU performance that's lacking.
