I think ARM themselves once put out an official statement saying that they considered 1.3Ghz to be the optimal operating Frequency for an A15 core in a smartphone (considering the increased performance of successive cores like the A57 and A72 I can't see that this number should have gone up)
Your probably all going to hate me for this (more so than you already do :) but after returning the Z5 I bought the iPhone 6S, I have found it's performance to be superb. Even when setting the device up and restoring an iCloud back up (from an earlier iPhone I once owned) two things that normally make any smartphone quite hot, this phone didn't even get warm.
I have yet to play any long gaming sessions on it so can't speak to it's thermal behavioural properties in that regard, but so far it has been highly impressive.
Surprised as to why Sony didn't use the S808 in this thing. It's cooler and less controversial than the S810. The 720p display ain't gonna draw that much of a power, anyways...

It's the objectivity of his opinion I doubt, Though I hate the term, TannHauser is a true 'fanboy' oozing pro Sony Bias, and like his ilk he will be inclined to prattle on endlessly about Sony Products pro's and reject out of hand any con's (and attack those who maybe voice them).
I don't do brand loyalty as a rule, as such I am free to focus on the pro's and con's on any product I buy, but considering the price we are asked to pay for flagship smartphones I do tend to focus on the con's when I see them.
With regards Snapdragon SoC's, I have in the past had many and enjoyed them all (more or less), it's not until the 810 that I have actually returned one based on the SoC itself.
That said you seem to be more far more level headed than the others I have had exchanges with in this thread and as such I do to accept your opinion of negativity towards your experiences with Snapdragon devices.

After that, there seems to be a progressively worsening current leakage, heat production, and battery waste. You can apparently get away with 1.8GHz just fine, though. Even apple iPhone is having issues trying to clock their processor at 1.8GHz.
And yes I know it's comparing apples and oranges, but trying to clock things too high is problematic. I bet the iPhone 6 SoC will fare better long term than the 6s'

Would be eager to see how the Exynos 7420 and Apple A9 stack up efficiency wise, and then add the Snapdragon 820 to that equation when available.
Like I said I believe 2015 has been something of an off year for Qualcomm and that is due the fact that they are out of their element when not implementing their own custom architecture.
Adiyel, 09 Oct 2015This has been an option since the kitkat and SD801 days. If you look in the power management s... moreYes your right many phones have had this option for while now, usually is under the 'restrict performance' heading of a power saving function. The problem with this being a proposed solution to thermal issues however is that the power saving function usually comes with a number of other features that have to be enabled along with restricted performance, most namely:
1. dimmer screen
2. restricted data access
I don't think anyone would be happy to required to run their device in power saving mode constantly due to performance issues of the SoC as standard.
Besides this I believe is different though from actually down clocking an SoC out of the box so to speak. like I said Oneplus seems to have had success by simply clocking the 810 at a max of 1.8ghz, but it seems other OEM's want to maintain that magical 2ghz number for marketing reasons.
At 1.8ghz the 810 seems to behave just fine thermal wise, ok it's performance figures are then more in line with what the 808 offers at least CPU wise (which are by no means bad), but it still has the benefit of the 430 gpu and superior ISP over the 808 (and other smaller advantages).
Correct me if I'm wrong but didn't Sony attempt to 'fix' the thermal problems the Z3+ was having by issuing a firmware update that did reduce the SoC max frequency, or at least limit the use of the four A57 cores???

Started off at 28 degrees idle, played Asphalt 8, Lara Croft Go, Hungry Shark and some Shadow Fight 2. Max temperature after 45 minutes was a mere 36 degrees... if I was using SD or MTK I'll be exceeding 45-50 degrees by now. I'll say it again, the Exynos SoC is the most efficient chip in the market right now.

Like the guy you quoted "Z5 and its variants ARE the best flagship phones at this moment" he hasn't even tried it.
There's no saving the SD810, be it v2.1 or not. The Crapdragon's heat in several earlier devices I've owned was the reason I sold them.
honest opinion guys
z5 compact or nexus 5x 32 gb.
Since I am in Europe I have 70Â€ price difference.(529Â€ for the nexus 5 32gb and 599Â€ for z5 compact. If I was in Germany(only) z5 compact would have been 549Â€)
Currently I own lenovo P770 (excellent battery life, no software updates).
need a new phone and a good suggestion

Ale, 09 Oct 2015Maybe, but that would just be a concession from Sony that there was an issue in the first placeThis has been an option since the kitkat and SD801 days. If you look in the power management section of settings, the stamina mode option can be both toggled and entered. Once you enter stamina mode, there is an option called "extended usage." It says that it will "restrict device performance to increase battery time."
If you can interpret this, it means they UNDERCLOCK the cpu. It has nothing to do with heat, but everything to do with battery savings

You say "Z5 and its variants ARE the best flagship phones at this moment."
Well that is your opinion pal (which of course you are welcome to) but it carry's no more or less weight than anyone else's, in fact, as you are known on here for your obsessive pro Sony bias, I would say your opinion has a tad less oomph to it.
Still defending the 810 to hilt (despite increasing evidence to the contrary) I see, and for the sole reason being that it is the SoC used in the Xperia line you so adore. Had Sony opted to use a chip from another OEM, I highly doubt you would care one way or another about the 810!

Now maybe they do on the Z5C though, it is a thicker bodied device, so may have more space available for thermal dissipation perhaps???
Clocking the 810 lower seems to have done the trick on the OnePlus 2, as far as I know there have been no performance issues relating to 810 thermal control reported on that device???
