This is an interesting test. Looks like apple doesn't throttle at all. I don't know if they are totally confident about their cooling or what but it will be very interesting to see how long they can sustain this. If they don't have any hard limits on 4k recording time, I'm pretty sure the recording can go on far an hour or two with the 128gb variant. Some guy put up a 30 minute+ video of iphone 6s plus recording continuous 4k. I must say that is pretty impressive.

What is the highest reported temperatures for unthrottled SD810?
[Nexus 6P Q&A, Help & Troubleshooting] Batfink33:
To be fair, the IPhone 6s is only pushing 1334x750 pixels, that's not even 1080. That'll be one reason it's not heating up as much.

Cheap parts? Qualcomm sd processor, Samsung ddr4 Samsung amoled panel sony camera sensor.... And more I'm listing.... Samsung makes all their junk in house to keep costs down. And I say junk because premium hardware with touch whiz **** on it doesn't make for a premium phone.
[Nexus 6P Q&A, Help & Troubleshooting] cb474:
I don't know specifically how hot the 810 has gotten. I'm not sure it's really the relevant way to look at it. Because, of course, with v2.1 it doesn't get that hot, since it throttles to prevent this. I do know that some of the early 810 phones without throttling had issues where the phone would spontaneously shut itself down. That is the extreme measure CPUs take to basically avoid melting. So that means the 810, without throttling, pretty easily reaches its design limits. That's usually around 105 C, I think, for CPUs.
[Nexus 6P Q&A, Help & Troubleshooting] Abu-khulzat:
I agree completely with all the argumentation regarding the big flaw in the design of the SD810 SoC. However, I have a question: do you guys think that Nexus 6P will perform worse than other phones out there?

As far as I know, all flagship devices use this chip but Samsung. I own Note 5, international version. So I witness personally frequent hiccups of the TW despite having the best hardware in the market. There are lags while scrolling in youtube, in recent apps switcher, and many other 3rd party apps. Sometimes expanding notifications drawer is not smooth too. Poor ram management doesn't let you enjoy 4Gb of RAM. Apps are forced out of RAM. These are all known issues.

I personally don't see any other alternative in the market if you'd like to get a really smooth device other than the new Nexus. If you go for any other brand having SD810 chip, you are not winning, perhaps you will get less smooth performance due to a custom skin. If you go for Exynos 7420, which is very powerful and doesn't have the heat issue, you still lose, due to TW's failing to utilize the chip effectively.

So it seems to me that even with the throttling chip, Nexus 6P is still going to be smoother and less laggy than all other devices in the market.
[Nexus 6P Q&A, Help & Troubleshooting] M@rs:
maybe the s810 throttles (high chance), but even if it does, we still can tweak the kernel. (Uv, disable cores, tresholds.) This will slow down the phone too but it's still on par or better than an s808.
[Nexus 6P Q&A, Help & Troubleshooting] cb474:
Nope. ArsTechnica ran this test and showed that the 808 is much faster than the 810, once the 810 starts throttling. In fact, in their review of the LG G4 they found that the 808 is faster than the 810, in many instances, even before the 810 starts throttling (when running cold).

See: http://arstechnica.com/gadgets/2015/04/qualcomms-snapdragon-808-doesnt-get-so-hot-under-the-collar/

And: http://arstechnica.com/gadgets/2015/05/lg-g4-review-more-than-competent-but-less-than-stunning/2/

People need to get over the idea that somehow the 810 in the Nexus 6P is going to be ahead of or even tied for the top of the pack. The reason Google chose the 810, as I say above, is not for the CPU performance. They're putting up with the somewhat subpar CPU performance in order to get other benefits of the chipset. The 6P will most likely just be in the middle of the pack, somewhere, or even only on a par with year old phones. It's not Google's fault. Qualcomm screwed phone manufacturers with the 810. But it is what it is.

(By the way, the first of those two Ars articles also addresses a topic that has come up in this thread. Just because the 810 has had issues in all previous phones, should we assume it will in the 6P? Ars says that from years of testings phones they've found that the same chipset in different phones pretty much perform the same and have the same issues. So, they say, they expect the 810 in any phone to have heat issues.)
[Nexus 6P Q&A, Help & Troubleshooting] Geordie Affy:
Before it gets hot enough to throttle, I'll just throw it in the freezer. Problem solved!

I was intrested at reading this thread at first now I'm bored. Will see how it performs on day to day tasks like web browsing, watching videos and youtube etc, if all is well I will buy it if not then I will have a think what to do next.

For now I'll wait for the thing to release before I make a judgement eitherway.
[Nexus 6P Q&A, Help & Troubleshooting] cougzzz:
My moto x pure with 808 had its share of issues too. With its inferior gpu and 2k display, the phone seemed to be taxed resulting in microlag and heating issues. Also coming from a htc one m9 as well, the 810 felt smoother in everyday experience despite its known indication for throttling its cpu. But then again, htc only had a 1080p display.
[Nexus 6P Q&A, Help & Troubleshooting] ambervals6:
Throttling the cpu due to heat is my main concern with this device.

[Nexus 6P Q&A, Help & Troubleshooting] michaelearth:
The Snapdragon 810 in the 6p is definitely worrisome, to a certain degree. However, with all the information available regarding the 810's thermal issues, one would hope that Google and Huawei came up with a solution to it before putting it in their flagship.

With that said, some people are dismissing this device before its even released which is never a smart move. I'm going to keep my preorder and hold judgement until its in my hands. Also, everyone has two weeks to return the device for a full refund, so there is almost no risk involved.
[Nexus 6P Q&A, Help & Troubleshooting] Batfink33:
One things for sure, Qualcomm have completely messed up with the 810 and they've done over a lot of phone manufacturers in the process. No matter what version of the 810 you have, there's inherent design flaws in it. They need to knock it out of the park with the 820.
[Nexus 6P Q&A, Help & Troubleshooting] michaelearth:
Couldn't agree more. The 820 needs to be flawless if Qualcomm wants to stay on top. It's really too bad that Texas Instruments stopped producing the OMAP processors. They provided some real competition to Qualcomm that I think is desperately needed today.
[Nexus 6P Q&A, Help & Troubleshooting] madmike23:
All those SnapDragons heat up unbearably time to time when you play heavy games. Its just not the 810, it's all of them (eg. Galaxy Notes and S's). Zenfone 2 has Intel and handles everything like a champ! I stunned why there aren't more Intel phones out there.
[Nexus 6P Q&A, Help & Troubleshooting] XRaptor29:
One of the reviewers that got to play with the Nexus 6P for 10+ minutes mentioned that he didn't feel any heat issues on the device and that it stayed quick and responsive.

While that's true, he was the only one that noted that. No one else did. He also mentioned that it was a demo model and that further use with the final product would need to be to confirm the over heating isn't existant.

I'm sure Google has worked with Qualcomm and the Android team to optimize the 810.
[Nexus 6P Q&A, Help & Troubleshooting] LNJ:
This thread is like a broken record. We all know that the SD810 is a dud. No need to keep repeating it.
[Nexus 6P Q&A, Help & Troubleshooting] cb474:
I don't think the fact that Google and Huawei put this in their flagship means they are confident they came up with a good solution. It just means, there's not really a good choice out there for them this year. So they're putting up with what they have to put up with.

But I'm not dismissing the phone, despite having insisted above that people who think the 810 in the 6P might somehow magically not have problems are fooling themselves. I think if the 810 is throttled properly it could turn out to be fine, it's just not going to be amazing. If it's good enough, I'll be happy to get a 6P. But I think good enough is really all we can reasonable hope for. It won't be the fastest phone out there or even at the top of the pack. It may not outperform year old phones. But I'm waiting for reviews.

*

As I explain above, there's no reason to expect problems with the 820. Qualcomm designed the 810 in a way not following their normal practices, because they were trying to have it be a 64 bit processor to compete with Apple's first 64 bit processor, when they weren't ready yet. The 810 really is an outlier. With the 820 they've gone back to their usual design process, so there's every reason to expect it to be fine.

*

That's really not a meaningful way to test the phone. It couldn't be less scientific. You have to leave it running something that puts full load on the processor for 10+ minutes, before it starts to throttle. Just playing around with it for 10 minutes wouldn't provoke the problem. Read ArsTechnica's article about the 810 linked to above to understand better. Most journalists just don't seem to have the technical know how to test the phone correctly. There are a lot of bogus articles out there, even with phones that have the 810 and are known to have problems, that run a test or two, in the wrong way, and say it's fine. That's just ignorance and bad journalism. Or they don't care and they're just hyping the phone, because their articles are really advertorials.
[Nexus 6P Q&A, Help & Troubleshooting] oneandroidnut:
Has the 810 been solved with marshmallow though? I think it was all software that made these chips run hot
[Nexus 6P Q&A, Help & Troubleshooting] Batfink33:
No, in the 810 it's a hardware design flaw. The heat can be limited with software tweaks like thermal throttling (reducing the maximum CPU speed as the chip gets hotter, but this impedes on the performance) the heat design flaw in the 810 can never be solved.
[Nexus 6P Q&A, Help & Troubleshooting] clorbag:
Many op2 users are reporting that the 810 is performing well even under stress . I'm not worried about it tbh nexus devices are known for their best of the best devs and lots of interest so it will work out
[Nexus 6P Q&A, Help & Troubleshooting] jonny_mako:
I think one plus made some optimizations with their oxygen os so that they try to keep adjacent cores from activating for as long as possible. Hopefully google has done the same with 6p.
[Nexus 6P Q&A, Help & Troubleshooting] Batfink33:
Remember, the OP2 is only 1080. The N6P is QHD so the CPU and GPU will be working harder to push the extra pixels making it warmer.
[Nexus 6P Q&A, Help & Troubleshooting] oneandroidnut:
I understand that and know the 810 has been a hand warmer ever since it come out in the g flex I think? I find it odd Android's code is still lacking
[Nexus 6P Q&A, Help & Troubleshooting] LNJ:
Also the OP2 is underclocked by default.
[Nexus 6P Q&A, Help & Troubleshooting] ambervals6:
Their optimizations = underclock to keep heat down. Underclock = performance decrease = same as having 2013 device.

This is from op blog: https://forums.oneplus.net/threads/oneplus-2-cpu-qualcomm-snapdragon-810-v2-1.316786/

As for software, OxygenOS has been optimized to work beautifully with the Snapdragon 810. We’ve created a proprietary technology, which handles a variety of tasks for the chipset inside the 2. Of the aforementioned eight CPU processors, these vary in size for different tasks in the phone. For example, one or two of the larger processors would be used for graphics-heavy gaming, while in contrast, the small processor would be used for simple text messaging. In layman’s terms,

one of our ROM’s features is to intuitively know which processor should be used for what task, and it avoids using two or more processors that are right next to each other

[Nexus 6P Q&A, Help & Troubleshooting] cb474:
In their review of the OnePlus 2 (which I've already linked to only a couple pages back in this thread) ArsTechnica shows that it throttles heavily, once the CPU heats up, like all other recent phones with the 810. The OnePlus 2 did nothing special to mitigate the issues with the 810, this is just marketing hype (which if any company is the champion of marketing hype and undelivered promises it's OnePlus). The throttling is done by updates Qualcomm made in v2.1 of the 810 chipset and has nothing to do with anything OnePlus did.

http://arstechnica.com/gadgets/2015...s-the-wrong-corners-to-stand-out-on-a-budget/

You can see in ArsTechnica's tests that once it heats up, the 810 in the OnePlus 2 has a performance drop of about 50%. It's only barely faster than the 801 in the OnePlus One; indeed in several tests it's a good 25% to 30% slower than the 801 in the OnePlus One. And it underperforms the 808 in the LG G4 as well.

This is a perfect example of how manufacturers hype up some bogus claim that they've dealt with the problems with the 810. But then in tests it performs exactly the same as it has in every other phone. As Ars notes in a separate article (I link to it above), form years of testing chipsets, they have found that chipsets pretty much don't vary in their performance from one phone to the next. It's not the phone and the design of the phone that determines the performance of the chipset. It's the chipset's intrinsic design itself that determines its performance.

No one is saying the 810 is not a good chipset. It's just not better than chipsets of a year ago or technically lesser recent chipsets like the 808, as far as CPU performance goes (as long as it's throttled properly--without throttling it overheats and causes serious problems). But the 810 does have other non-CPU related advantages.
[Nexus 6P Q&A, Help & Troubleshooting] Xileforce:
The knowing which processor should be used for which task is not a special feature to their rom. That is qcom heterogenous multiprocessing software and scheduler stuff in the kernel. The hmp is what allows all cores to be used at once and schedules tasks appropriately depending on its needs to one cluster or anothe or both. I don't know about the not using cores next to each other though. That could be normal Qualcomm behavior too or they did something special themselves.

Fake 810 overheating rumors

A long read but VERY informative.

[Nexus 6P Q&A, Help & Troubleshooting] Batfink33:
Lol, "fake". That'll be why there's multiple versions of the same processor and phone manufacturers having to build in specialised cooling in their devices.
[Nexus 6P Q&A, Help & Troubleshooting] Xileforce:
That article doesn't seem to line up with numerous scientific testing articles done by the likes of ars and anandtech, nor with other users who have used the 810 in other devices. Plus we have seen companies like Sony develop their first device with 810 and then have to make another with enhanced cooling(z3+ and z5) in order to fix heat issues... If the 810 had no heat issues why would Sony spend the money to upgrade the heating in their device?
[Nexus 6P Q&A, Help & Troubleshooting] turboencab:
You mean the part where they say, "...it seems that Snapdragon 810 was not as the rumors claimed. In my experience, I didn’t notice any of the development devices getting hotter than what I’d come to expect from a modern SoC."

[Nexus 6P Q&A, Help & Troubleshooting] Xileforce:
That was not only a reference device but also a tablet.... Which allows significantly more area for cooling the SOC and they were likely given a perfectly binned processor to test. If you look at their review of the sd810 v2.1 you will see they mention that while heat issues are improved, it can still hit points where all of the a57 cores turn off.
[Nexus 6P Q&A, Help & Troubleshooting] jonny_mako:
Is Android (and apps) just too advanced in terms of multi-threading that heat becomes an issue with quad (A57) cores?

Heat has never been a problem with the Exynos and it's A57 cores?

I actually think you'd get better performance using an 805 in the N6P. It's without a doubt Qualcomms best SOC to date.
[Nexus 6P Q&A, Help & Troubleshooting] Xileforce:
It's not the A57 cores. The exynos 7420 doesn't have these issues. The only difference is its designed by Samsung and built on a 14nm process, but it uses the same cores. The exynos also scores around 70k in antutu whereas we see around 50-54k for the 810 devices. I would imagine that's mostly from thermal throttling and some performance improvements from 14nm.

If the 808 preforms better, due to not throttling, couldn't we just disable 2 of the a57 cores with kernel modifications and underclock to 1.8ghz? Isn't that the difference between the 808 and 810?

[Nexus 6P Q&A, Help & Troubleshooting] jal3223:
I have the opposite experience with the G4. Mine is idling right now at 23c for example (CPU temp). I don't play games much on it, but when I'm surfing and doing a ton of multitasking it may get up to 48-50. The 805 in my Note 4 would hang around 60c using multiple tabs with chrome or heavy multitasking. Although that could have a lot to do with touchwiz.
[Nexus 6P Q&A, Help & Troubleshooting] Batfink33:
60 on the Note 4?!?! Mine idled at 40.

The worst phone I've had for heat was the G3. That idled at 55 and throttled like no one's business. The G4 isn't great for heat but its nothing like the G3.
[Nexus 6P Q&A, Help & Troubleshooting] jal3223:
Mine idles at 40 as well (Note 4). I meant if I put it under any stress it would quickly rise to 60c or above. I have it rooted with the temp displayed in the status bar.

I have to agree with you, the G3 was terrible. The heat was the main reason I got rid of that phone after only owning it a few weeks. I've had good luck with the G4 though. Maybe the quality control sucks between units on the G4 because according to all of the measuring I've done it's stayed the coolest of any 2k device I've owned.
[Nexus 6P Q&A, Help & Troubleshooting] Batfink33:
I sent my G3 back after 3 weeks it was one of the worst phones I've owned, the throttling made it unusable at times. I just don't think the 801 could handle the QHD display.
[Nexus 6P Q&A, Help & Troubleshooting] oneandroidnut:
Agreed the mxp and g4 I had were hand warmers. Terrible laggy ovens! My note 4 that is a year old runs like a champ and full multitasking and intensive tasks don't get it as hot as idle on g4 or mxp. I'm telling you the 808 & 810 are junk. That's why I haven't ordered nexus 6p
[Nexus 6P Q&A, Help & Troubleshooting] cb474:
But the 810 has been a nightmare in most phones it has shipped it, so that shouldn't be a surprise. Also, ArsTechnica's tests were comparing the phones based on their performance and how much the throttling on the 810 affects it. They were not making comparisons based on heat to the touch. I suppose it's possible the 810 is cooler than the 808, due to throttling, but also underperforms it.

Honestly, I'm fine with the 810 throttling, as long as it's good enough for day to day use. Like others, I don't want a phone that feels really warm all the time. I'm still using a Nexus 4 and it's warm a lot (although I didn't notice this until the last year, it was fine before that). It tends to idle around 40 C, but quickly gets to 50 C or 60 C if I run just about any app. Obvioulsy for me, whatever the performance limitations are of the 810, even throttled it will be an upgrade from the Nexus 4, as long as it can handle the high res display. But having another phone that's super warm to the touch all the time would be annoying.

---------- Post added at 12:56 PM ---------- Previous post was at 12:48 PM ----------

I'm not sure if it's accurate to say its the same A57 cores. My understanding is the chipset manufacturers take the designs from ARM and then customize them to their chipset. But with the 810 (as I've said above), Qualcomm was caught by surprise when Apple released a 64 bit chipset before people expected it. Qualcomm didn't want to be the only one, for a year, without a 64 bit chipset, so instead of customizing the design for their purposes as normal, they used the "off the shelf" design for the A57, without changes. And this is what caused the heat problems.

So the A57 as it exists in the 7420 is not really the same as it is in the 810 and hence making comparisons and saying, "why are there no issues with the 7420?", is really comparing apples and oranges.
