Galaxy S5 with QHD and Snapdragon 805 announced

http://www.engadget.com/2014/06/18/korean-samsung-galaxy-s5-has-qhd-snapdragon-805
Only for Korean market.

Oh Dear.... soon to be an influx of Samsung haters, saying the usual things like Samsung can go to hell, Samsung betrayed us ect ect ect.
Me i will continue to enjoy my bog standard S5, until i decide next year what to replace it with.

Too bad it's a korean exclusive for now

I still don't see how anyone could be surprised about that.
Or has everyone forgotten about the S4 Advanced LTE-A already?
Honestly people, business as usual...

Did S4 advanced have a better screen than S4 ?

Out of interest, will it ACTUALLY be that much/if any faster anyway?
Would be interested if anyone with the tech knowledge could chime in....because it seems to me that the slightly faster snapdragon 805 is probably 'cancelled out' in effectiveness by the fact that the handset is now having to power a quad hd screen instead of standard 1080p.
Thoughts?
I can tell you for a fact that my gf's older macbook pro is snappier in day-to-day ui movements than my newer retina mbp which I'm guessing must be due to the added strain of those extra pixels.

There's been quite a bit of discussion in the M8 comparison thread about the impact of QHD on the LG G3. Cliff notes:
- Performance on S-801 took a pretty big hit
- Battery life took a hit
- Display contrast, black levels, and reflectivity all took hits
S-805 isn't a minor upgrade. It and Adreno 440 should allow QHD to perform as well and most likely better than S-801/1080P. So battery life and the quality of Samsung's QHD display are questions left to answer. The M8 thread also has discussion on the value of going from 1080P to QHD which is really pretty limited.

Performance isn't 'canceled out' since the 805 can handle Ultra HD (4K) screens. The following scteenshot is from Qualcomm's site which summarizes the specs of both the 801 and 805. Snapdragon 805 breakdown

However, QHD content is currently limited to whatever bloat comes pre-installed from Samsung and wallpapers you can find online . As a result, people can't yet take full advantage of of that high res screen until app developers update their apps and there are very little YouTube videos above 1080p.

3GB RAM vs 2GB in the S5.
Great Samsung. Great.

That phone is a beast. But so is the regular galaxy S5. I don't think ppl should be upset really, its business. If you enjoy your phone then just enjoy it.

There will be little or no QHD (2K) native content. Commercial content will be 1080p or UHD (4K). That means it'll be up and down scaled which impacts image quality. QHD is a marketing ploy of questionable value. Lots of reasons supporting this in the M8 comparison thread.

This is indeed a good read regarding Snapdragon 805's cpu and gpu power.
http://www.anandtech.com/show/8035/qualcomm-snapdragon-805-performance-preview
From there I got couple important points:
The 805 can handle a QuadHD resolution device at the same frame rate and with same performance that an 801 can drive a 1080p device.
It is said to use 20% less power and provide 40% more performance compared to an 800 SoC
The 805 has small (comparatively) cpu boost and significant gpu and video engines boost.
The GPU tests were there. It nailed pretty much everything.
The 805 has HEVC HW decoder, but no HEVC HW Acceleration until the 810 SoC comes out in H1 2015.
I personally did not know what HEVC was. It is actually H.265 codec that provides magnificent video output at much lower bitrate than ax264/h.264 encoded video.
I curiously downloaded Big Buck Bunny 1080p encoded with HEVC that sized only 130 MB. The h.264/x264 encoded video was available at the Big Buck Bunny's official website to download which was roughly 700 MB. The 130 MB file indeed provided great output compared to its regular 700MB variant!

The only thing I´d like in my S5 is 3GB ram. I do not want a QHD display which will only drain extra battery without me even being able to tell the difference.

Why would you like 3gb of ram? Have you ever run out of it on your S5?
Sent from my SAMSUNG-SM-G900A using XDA Premium 4 mobile app

Yeah alot of times, many apps have to reload when multitasking, it´s clearly not as good at multitasking as the note3 for instance.

So true. Someone above wants S-805 because it's "faster." Faster at what? 85% of apps don't use more than two cores according to Qualcomm. Screen transitions and app openings certainly don't need S-805. In every upgrade cycle (720p/S-600<>1080p/S-800<>QHD/S-805) the potentially huge gains in performance and battery life ended up minor because of the resources consumed by the display. Let's see some benchmarks from the SGS5 LTE-A before everyone wets themselves over it. Display quality took a big hit on the LG G3. Let's see how Samsung does.

Yeah, that's exactly why I asked. I don't think people understand how ram works, they just want more because it sounds good.
Unused ram is exactly that, unused ram. No matter how many apps I've had open at once, I've never reached near 2gb of usage.

That´s because the phone hibernates apps before it ever reaches full RAM usage. More RAM = more open apps which allows for faster multitasking. You´d think this was basic knowledge by now.
I´m sure you all have switched to an open app only to have it reload like it was first opened.
Coming from an iPhone with 1GB of ram I am overly aware of this issue.
And no I do not want the new S5, I just wish Samsung had put 3gb in the S5 in the first place, like they did in the note3.

New Mi3 in 2015?

I just want to know if it makes sense to buy this device in 2015? I always buy midrangers and don't like shelling out more money. So, what are your thoughts on this? With Lollipop supporting 64-bit does waiting for Moto G 2015 makes sense?

I think yes . It' s very fast and good

I have a Mi3 and i'm very glad with it, bought it in February.
But if it was now, i'd probably go to the Mi4i, It comes with MIUI V6 based on Android L and it's a Snapdragon 615 (64bit)

The 800's CPU, on paper and benchmarks, yes. (Antutu on my Mi3, running latest beta MIUI V6 is on the 43k mark)
The GPU is not that different on actual performance, but the 615 is much more energy efficient.
The 800 (as well as the 801 and the 805), are beasts but warm up pretty quickly and Qualcomm's MP-Decision hotplug does not take very long to cap the CPU to half the speed, because the SoC goes very near the 60ºC mark in no time under heavy load.
If you read the news, that's why the 810 is a flop, they pushed the Krait architecture beyond what it can do, and they turned a mobile SoC into an instant frying pan.
Of course, you can always ditch MIUI, go to a Custom Rom along with some custom kernel, ditch MP-decision too, and go with manual frequencies... but then again, if you risk too much heating, the SIM card slot fries (because it's the only place on the Mi3 that expels heat more rapidly), the touch screen begins to take damage and after a while you'll be replacing it, and in the end it will render your phone useless.
Don't get me wrong, i love Krait based Snadragon's, especially the 800 and the 801, but the new 615 and alike, are made with smaller architecture and are much more energy efficient, which means, more battery friendly, and can sustain heavy loads for longer time, because they don't heat up as much, or as faster as their predecessors.
It's not the paper sheet specs that count in the end, it's the day-to-day real performance and behaviour that shows whether a specific SoC is really that good or not.
The PC world learned this some 10 to 15 years ago, when Intel lauched the Pentium 4's with ridiculously high frequencies, everyone was mind-blown to see those speeds right of the shelf, but everyone pretty much realized that those CPU's were pretty much useless in no time, unless you had expensive custom cooling on your setup. Qualcomm made the same mistake.

IMO SD800 is the better option. Here's a couple of reasons why:
* big.little is relatively new tech and needs more time to mature. It might look good on both performance and battery life fronts on paper maybe, but is there really any one phone in the market currently that beats current SD80X in both performance and battery life? (GSMArena's reviews suggest that Xperia Z3C is the recent gen phone that scores solidly on both counts and it runs on a SD801. One other phone with a better battery is the OnePlus One which also runs on the same chip.). The funniest thing that I find about SD615 is that big.little is supposed to bring two architechtures together as it was demoed using Cortex A-15 & A-7 clusters, but both clusters of SD615 are A-53 (A53 = 64bit A7).
* Both SD80x and SD615 are build on the same 28nm process. The HPM process also supports ultra-low modes which LP doesn't. More here: http://www.tsmc.com/english/dedicatedFoundry/technology/28nm.htm
* SD80x can give you both performance (on >2Ghz) and battery life (when underclocked) though not at the same time.
* Finally the Adreno 405 on SD615 is less powerful that the Adreno 330 on SD80x.
These are just a few reasons that came to mind. I am sure that I can find many more reasons if I looked around a bit more.

If you flash roms, go for moto G. If not, go for Mi4i

Sorry about the architecture comparison, i had the idea that the newer 615's and alike were not 28nm.
Still, does the 615 heat up as much, or faster than the 800 on the Mi3? I'd like to know more about that, because what i was saying was, the 800's are more powerful, but they heat up fast, so in some heavy tasks, they get capped pretty fast...
So unless you put it in "performance", the CPU and GPU will be put on lower freqs in just a few minutes of gaming for example...

You can see that throttling is not as bad as earliest SD800 in Nexus 5 and Note 3. This is because the 8274AB is actually the 3g version of 8974AB v3 a.k.a. SD801. More info here and here.
Bonus: Mi4i also suffers from overheating back. Video here

If anyone is wondering, I did get the Mi3 and it totally rocks!

MI3W (Over)heating

Hi all,
So I got a question related to MI3W, the cooling system of it, and mainly:
Is it normal that while I'm doing basic stuff like internet browsing, using Tapatalk, Skype, whatever, the phone temperature is usually around 45-60°C? I think that's waaaay too much. Also I can feel the back and front of the phone(display) heating a lot. One thing I would like to say is that it's not dependent on any ROM or kernel, I'm facing this issue even in MIUI.
Now, this is not such a problem, but, the real problem appears when it comes to games or performance demanding apps. To get higher framerate or performance, I switch to High Performance mode (performance governor). But then, the SoC temperature rises to 90°C and I can't even touch the display so I won't burn myself.
Now, this sometimes happens even in idle mode, even though it's not this high temperature, but still it's about 60-70°C.
It could get pretty unpleasant if I received a call and had to put the burning phone on my face.
So I'm wondering if there's anything I can do with this issue and if anyone else has it, and if this is eventually an issue of the whole MI3 model.
Last thing, no other phone with S800 has this issue, I saw Xperia Z1 mini and Nexus 5 and none of them had such a crazy temperatures, I know this version of S800 is the one with overclocked GPU but still, it's not that much of difference and I don't think it receives any right to heat as much as it does to me.

This app is actually accurate, CPU-Z reports the same temperatures, it just shows more sensors so I thought it would be better to just show a single temperature..

Not sure what the single one is, but i'm sure it's not the SoC temperature. CPU-Z of my friend who owns Xperia Z1 mini was showing 30-35°C in the tab with many sensors. Even after calculating Pi to 10,000,000 decimal places it didn't go above 40°C.. and his calculation time was even higher than mine. I found out that the calculation time is dependent on the SoC temperature, if it's overheating then the performance is lower. So I can't try it more times because it usually rises to 60-70°C.

Okay, thanks for letting me know it's not an issue just for me but in general. I like this phone but I'm a bit dissapointed by this not well thought off cooling. I'm sometimes afraid the heat would destroy the LCD at one point because sometimes it's really intensive. Mostly after flashing an update for a ROM and upon the "Optimizing apps" screen.
One strange thing that I don't get though, is why nobody else is complaining about it, nor any reviews of the phone are mentioning this excessive heating.
I've been thinking about this for some while now.

Don't use while charging and stay with balance power profile. These are mainstream device so don't push these to limits very often (these are not dedicated gaming device) and limited passive cooling for SOC. Otherwise you will inviting a premature component failure. Device temperature is also closely associated with ambient temp so if your ambient is close to 24is C the device will sustain performance bit better.

The problem is I can't use it while charging anyway, because the phone otherwise discharges faster than charges.
Also mostly I use balanced performance mode, since I know it starts to heat a lot and it gives me way too much performance for what i need most of the time. But when it's time for games, I need to use high performance mode otherwise the game isn't running so smooth. And in case of Piano Tiles, I experience unpleasant random stuttering of the game, which pretty much makes it unplayable. And that's not even any resource demaning game. So I'm forced to switch to HiPerf. mode anyway But it's really not that I'm overloading the phone and having it as a rendering station
About Mi3 being mainstream: I don't believe it's mainstream for its initial price, even though it was cheaper than other manufacturer's devices. Anyway, I will be careful with it. Still I don't get, if this is a mainstream device, why did Xiaomi use S800 SoC? It was a flagship when it was released 2 years ago. To me it looks like a fail from this point of view, trying to make a mainstream device(not so much dedicated to cooling) using high end components(which in fact need a better cooling).

Unfortunately MIUI has bad thermal tweaks...blah blah..
So i suggest you to lower the screen resolution from FHD to HD (Not much of difference) and lower the lcd density. By this u will see hell lot of difference (I tested this method myself).
** Secondly try using a good ROM with Better cpu and thermal tweaks like if u want MIUI taste then try "SMIUI"
Or use Mettallium OS (I use this myself)
*** (OPTIONAL) u can flash some .zips that contain some tweaks and many improvement (u can find them on XDA easily)
like Lspeed etc.
I was facing the overheating issues but lowering down the resolution does the magic.
U can find resolution guide in MI3 GENERAL.
have a gr8 day

Yes it does heats up during installing roms (optimizing apps). I cool it off by air forced cooling (holding device in front of cooler during installation else battery discharges by 20 percent).
Normal heating during gaming, but stays cool in daily use... on cm 12.1 stock kernel

If you are using miui. Try God's Kernel R3 or R4. And report.

That seems to be the problem of Snapdragon 800.

Last thing, no other phone with S800 has this issue, I saw Xperia Z1 mini and Nexus 5 and none of them had such a crazy temperatures, I know this version of S800 is the one with overclocked GPU but still, it's not that much of difference and I don't think it receives any right to heat as much as it does to me.

Thank you for your feedback and hopefully this gets solved.

Okay, so a little update - Recently I reached an incredible temperature of 107°C on the CPU chip!!! And then thermally shut down. I think this isn't fun anymore. I don't know if i have some defective piece or if it's normal for all MI3's but I'm starting to think about returning the phone or just claiming a replacement. Both the front and back of the phone gets hot very soon, just by watching some youtube vids or browsing internet...or JUST having the phone simply unlocked and idling. The temperatures don't go under 40°C. I think that this is the reason why MI3 was cheaper than other phones with the same SoC.
In the worst case, I will revert the partition table back to stock, install latest MIUI 7 on it and send it to a service center.

Which rom are you using? And kernel?

The superhigh temperatures were in recovery and before the phone boots up. I was reaching 80-90°C in any ROM, including MIUI(while gaming) and 60-70°C at normal use. Sadly, no ROM affects the temperature, it's always high. I was using all stock kernels, until yesterday, when I flashed Moshi stock kernel, expecting lower temperatures. Well, they were lower, but still 60°C with JUST watching youtube videos, that's a bit too much.
I think Xiaomi just didn't think off the cooling well, because Nexus 5 and Galaxy S5 don't suffer from so high temperatures, 60°C at most while gaming, and people at forums complain about getting 50°C while i'm glad to have 45°C in idle state. And I'm not talking about the surface temperature, I'm talking about the on-chip temperature, which to me is more important.

GUYS - What if https://youtu.be/hZDNpp--E0Y was applied to MI3? Maybe my device is just poorly greased and the heat doesn't transfer to the aluminium plate effectively. That could be a solution, if it's possible, which I believe it is, because MI3 has the same aluminium plate on the back of the LCD as a heatsink(i believe it is aluminium).

I understand your problem. May be yours is a hardware problem. But try flashing God's kernel R3 or R4

Xiaomi Mi Mix slower than most Snapdragon 821 phones ?

I have been working far too long on this phone to make it perform as all other Snapdragon 821 phones perform.
I have zero understanding as to why this thing is so much slower.
Check the Antutu Benchmark results to see what I mean, most Snapdragon 821 phones are in the top 10 devices yet the Xiaomi Mi Mix is below the 20 mark and even beaten by a few Snapdragon 820 phones.
I can tell the difference greatly with both the OnePlus 3T and the Xiaomi Mi Mix right beside each other playing the same game.
Is there any way we can somehow improve the performance on this device.
I have tried running the CPU and GPU in performance mode , disabling the Thermal throttling with Kernal Auditor , underclocking to match the OnePlus 3T's lower clock speed. The CPU temp never goes above 38 celcius so it can't be throttling.
Wiped reformatted , tried Lineage , Epic ROM , Stock , Resurrection ROM and they all still underperform and as far as I know these are all odexed.
Please if anyone has any ideas let me know I'll try anything.

you must be high, it is on par with my galaxy s8

try a custom rom, like resurrection, and u will have a op3t performance.

i feel it pretty weird tho, for example, i just have the Mi5 (not s) and 32GB (LPDDR3), and i score 149-150K on Antutu, meanwhile the 64GB+ (LPDDR4) users score like 160-165K
and i saw a Mi5S scoring near 170K too, using MIUI tho and not custom roms, meanwhile on the normal Mi5 i score a lot more in Custom than in MIUI
Anyways don't take much in mind Antutu, it is very variable
the weird thing here is, that is going slow compared to the 3T, when it shouldn't

The device runs just fine when doing day to day tasks but when trying to play CPU intensive emulators it is much slower than the OnePlus 3.
This should not be expected as the specs are the same.
I am using the same version of the emulator on both devices with the exact same settings and the OnePlus 3 is always 10% to 20% faster on every game.
That adds up almost exactly to the Antutu score difference.

I looked into the details of the Antutu scores and the failing scores are mainly attributed the 3D processing sections, if it's not hardware then it must be software right.
There's no reason for this.
The only thing I haven't tried is a custom CPU governor , software driver manipulation , removing Qualcomm MP decision.
If you have any ideas or have done any work on this let me know, there is basically no information on the internet on why a soc would perform so poorly unless it was due to poor drivers or thermal throttling.

It might be cause MIUI's temperature control，you can try to delete it.

I too think so. When i ran Antutu(device was cool a bit); it wasnt getting full throttle because of thermal throttling although i disable it. What do you mean by 'try to delete it' though?
There is no custom kernel support on this device, somehow, nobody(devs i mean) interested in miui-kernel. The device has really bad kernel management, especially while getting charged from low percentages; feels the death. Perhaps shut down whole the cores smh.
Mi MIX
7.5.4 Épic

I think people should focus less on synthetic benchmarks and more on actual user experience... Just my two cents. The phone runs perfectly well, never encountered any sort of slowness or performance issues.

I've tried different ROMs (xiaomi.eu, epic, RR official and unofficial).
With stock MIUI (Android 6.0 based) antutu score: 145000
With stock MIUI (Android 7.0 based), RR and Epic antutu score: 160000 and over
My personal advice: don't worry too much for benchmark score, it doesn't represent the real potential of the smartphone.
I can't see differences in speed with all the ROMs. The Mi Mix works great in every​ condition.

My point wasn't getting a bad antutu score, the point was 'thermal throttling' trouble when device getting forced to slow down easily. Even performance governor gets no fuğk. Im checking real-time cpu and battery temperatures btw, no higher temps in case. There is no big deal tho, just getting some UI glitches in some apps makes me confused.
And the other thing while charging etc, whatever. I god dam like this device and Miui.
Mi MIX
7.5.4 Épic

There are better benchmarks than antutu... Mi mix goes.... FAST.(with little tweak)

I simply cut it from it's current location and moved it to root, the changes have been quite noticable, runs much better without it and it never gets too hot. Low battery impact here.

Which Hardware Revision do you have?

Hi,
After reading in another thread that there are different Hardware Revs i took another look at my Box and found out that's true.

So how many different version are there? Someone said he had Rev 3.
How is the distribution? Timebased? and How many of each...
And most important, what's the difference.... anyone knows anything?
So, as you can see in the Picture above, i got the H8216 in Rev 2.
What do you have?

I don't know about differences but I have revision 3.

H8266 revision 3 here.
I'm not sure if I am not noticing it, but I do not experience touch screen sensitivity issues when I play games or maybe they are minimal. Granted I play rhythm games and mobile rpgs, not fps or fighting games so maybe its just me.

H8296 Rev 2

H8266 Rev 3

This thread is pointless if revisions are not linked with specific comparisons in behaviour.

Revision 1, and I'm having massive heat issues. Recording videos, especially with SteadyShot, HDR and 4K activated is stopped after 7 to 10 minutes usually, because the phone got too hot. I'd like to know if later revisions fix these issues.

Does Revision 3 fix the hardware issues?

I have Deep Green H8266 (Rev 3).
I don't experience too much heating issue and don't experience touch sensitivity issue either. Battery life is great and can be really amazing, a lot of time (reaching the point where I'm struggling to drain the phone's battery at night, just because I want to charge the phone at 15%). It is also lightning fast, superb gaming performance, and has great multitasking performance, too.

H8266 Rev 4 here, just bought it a couple of weeks ago after frying my Z5p, I had no intention on getting this phone, was going to wait til the end of the year to see what Sony will offer but necessity obliged ?
Absolutely zero issues, no heat or screen sensitivity as other mentioned, this thing stays cool and is lighting fast, battery life is insane, crossed a few times 10+ hours of SOT...just waiting tight for a drm fix to root and xposed (whenever that is)
The only thing that bugs me is the esthetic of the phone, not a fan of the back side at all (finger print sensor works pretty damn well though, still prefer a side placing)

Interesting. I'm not getting anywhere close to those battery times either. Can you run the GeekBench battery test? I'm at 4 hours and something...

I will ask the support to repair my phone.
Switch it to the latest hardware revision.
And see if this fix my touch screen issue.

Impossible physically. The battery is not big enough to sustain that long of a SOT no matter how efficient you claim to be. unless sony changed the battery capacity in their latest revision, conning people who got earlier revisions.

I haven't had any of the issues reported, the phone never seems to get hot either but I don't play games very much and for the time that I just got slightly warm. I agree with the battery life, it's really amazing compared to everything else I've ever owned.

I've been on xda long enough and I'm not the type to post nonsense ?
This pic below is not from my phone, it's from the xz2 thread on Esato, so you can see that I'm not the only one either...I didn't take a screen shot of mine when I crossed 10+ hours (I will next time)... I said that passed it a few times, mostly range in the ≈9+ hours...
I don't game, few accounts with push notifications and an email client with 3 imap notifications (so those run in the background constantly)
This one below is from my phone...I'm at 1.5 hours of SOT with a 12% down from full charge...you can extrapolate the end results ?
System optimization is an important factor, not only battery size...they did a great job with the xz2...

and WHAT exactly do you want to test? We don't know what they changed, might the supplier from glue which holds the Screen on the phone, might be the a different speaker/microphone inside or something else smaller.
Else we wouldn't be a rev4 already. Changing something during production is no small feat...

Lol.
The Battery inside the XZ2 has:
Min: 3060mAh 11.6Wh
Typ: 3180mAh 12.3Wh
So i've measured the powerdraw for Screen+Phone Idle/flightmode:
Minimum Brightness uses 0.49W
Maximum uses 1.83W
Screen Off uses 0.24W
Doing the Math even at full brightness if you use your phone as E-Book reader you could reach 6h 45min At Minimum even over 25h!
So yes, it is very well possible.

Hm. Before the XZ2 I've had a Xiaomi Mi 6, which impressed me more in terms of battery. Smaller screen, bigger battery (and much slimmer phone).
And IMHO it's not better, perhaps worse than my LG V20. I did take a lot of photos, which does seem to drain the battery badly.
I really wonder what they have done through the revisions. It seems clear to me now that revision 1 had some serious flaws (or maybe my unit is defective), especially in terms of cooling.

Rev 2 i have
Wat is exactly the point of this... More info please and can you explain us what Rev 1, 2 and so on is and what it mean ?

No one except for Sony probably knows. But it is interesting to see, which revisions made it to the market and which didn't. And if people report on issues with their phone, we can at least figure out a bit what was fixed. Also now we know there are 4 revisions so far. Mine is revision 1 and says demo only, not for sale. So maybe it is also possible to find out when these phones were released.
