Japanese Sony Xperia Z4 users are already complaining of overheating issues

Japanese Sony Xperia Z4 users are already complaining of overheating issues
Well that didn't take long, did it? The supposed overheating issues of the Snapdragon 810 have been well-documented over the past months, but it was thought that a revised edition of the mobile chip had put paid to any lingering doubts. Yet following on from a recent clip of a prototype Sony Xperia Z3+ getting a little hot under the collar during camera app usage, it looks like early adopters of the Xperia Z4 are also having these troubles.

With the Z4 being just hours old in the Japanese retail market, Sony would have been hoping for a smooth, incident-free launch. But trouble seems to follow devices powered by the Qualcomm Snapdragon 810 just lately, as a number of (translated) tweets by Japanese consumers demonstrate:


Sure, a few posts on Twitter don't exactly constitute damning evidence that the Xperia Z4 is overheating. But what's telling is that retail stores across Japan are warning customers about the heating issues relating to its processor. They also recommend prospective owners of the Z4 power down the handset at regular intervals, power off during charging and take regular backups -- not the kind of hoop-jumping anybody would want to partake in after coughing up hundreds of dollars for a flagship device. 

Processor report tool CPU-Z also throws up some worryingly high temperatures in a reading from an Xperia Z4:


The fact that retailers are warning shoppers at the point of sale is not great press for Sony, nor indeed for Qualcomm. The chip maker has vehemently defended the 810, with the "revised" version of the SoC intended to ensure that overheating would be no more. The early reaction out of Japan suggests that both Sony and Qualcomm could have a real problem on their hands, and with the global launch of the Xperia Z3+ upcoming, it's one that quickly needs to be nipped in the bud.

Because the breath of the fiery Snapdragon 810 is too much to bear.

Beauty of Android. What was with that "platform-agnostic" crap? Almost non-existent.

Hey, my iPhone 6+ doesnt get any overheating issues even when im playing intensive games like Asphalt 8, Vainglory, FIFA 15, MC5, GTA : Trilogy, Infinity Blade : Trilogy etc. Well, premium brand, premium phone as always. A9 64 bit RULES!!! Android phones with overheating issues, so what do you expect? If you dont use iPhone 6+ premium like me, dont talk BS abt iPhone to me.

"If you dont use iPhone 6+ premium like me, dont talk BS abt iPhone to me." you are saying this to bobbybuster? OMG, Bobbybuster is a very well known lover of apple and hate everything beyond insanity which doesnt have a half bitten apple on it... if you like ip6+ then atleast you should give some respect to Bobby... SD810 turn out to be a nightmare for OEMs. This is what you get when there is no competition... now there are very less choices for OEMs to ditch QComm... this is the same very reason which make me hate apple, bcoz apple have a monopolistic approach too

SD 810 was not so much of a failure but it was the first octa core core chip of Qualcomm is better than the first of Samsung but it is the best thing that OEMs can have there is no alternative it's the only choice.

Samsung were the very first big little adopter. They got a few things wrong with it (ie, how both quad cores talked to each other, it was more like 4 + 4), but it did not overheat like this.. Makes me laugh, Qualcomm was offered a solution by Samsung based on all of their many years making Octa cores.... but Qualcomm chose not to take it.. such a shame. Some handset manufacturers will suffer a great loss over this...

It's qualcombustion not android, samsung s6 doesn't overheat

Samsung S6 do overheat under heavy use but it needs not note time than the SD 810 hope they used Intel CPUs it's much stronger in terms of performance while have less cores and frequency.

Huh? you obviously don't have one. I've played Asphalt 8 for a solid 3 hrs, and using CPUz afterwards, only 39 deg.. To me that is acceptable

It depends highly on the weather degree or situation you are in your home no phones probably overheat.

Nothing premium in your crappy 6+, 1GB RAM and a 1080P Display, those are late 2011 specs.

touch screen gaming, swipe here and there! wow! I am so impressed this type of gaming and non tactile controls, it's like using buttons to drive a car! while I use my dual shock 3 controller( with bracket) to play on my so called inferior xperia z2 phone

Zzzz idiot troll it's the sd810, not 'Android' in general. Sigh your stupidity is tremendous.

LG did it right by going with the 808 instead and it wasn't much of a trade off in terms of performance. I wonder what they did in the Revision 2.1 if it didn't mitigate any of the problems found in the earlier release.

OEMs should just use the 808.

qualcomm should have made Snapdragon 809, which basically an 810 with 6 cores and same GPU

4k recording is the hot stuff but even hotter with SD810!

The 810 is a defective product. There's no disputing it. I can't believe it's continuing to be used. The 808 or even 805 chips are more than adequate for any flagship and perform perfectly. Hell, even the 801 is fine. Specs are nothing more than bragging rights at this point. In real world use, last years flagships are just as fast as this years and everyone knows it.

It's not only S810...ARM's big.little architecture is equally responsible for excessive heat. It's failure on both fronts...if oems disable A57 cores completely and use only A53 cores...their heating problem will be gone easily.

It's Qualcomm's implementation of big.LITTLE the problem here. Samsung's Exynos 5433 and 7420 use the same core configuration and they don't overheat. Granted Samsung has worked with big.LITTLE for over two years now so they have the knowhow but truth be told, the first Exynos Octa was a complete mess.

Samsung always have heating issues since the note 2 good that phone was hot lagging issues and freezing in its Exynos socs it was never did since the 7420 one the big.little architectures is the one to blame quad core CPUs was just as good as octa cores.

Disagree.. you obviously had a faulty handset

SD810 is very rushed. Apple just scared the hell out of Qualcomm and they rushed, tripped and fell. And now Samsung kicked them a couple of times while they are down with Exynos. Next SoC should be custom and good.

True - Apple indeed caught them off guard. You probably recall this funny post about a QC executive's claims (who eventually had to step down). I still can't believe how they managed to be so behind with their custom 64 bit roadmap. http://www.phonearena.com/news/Apples-64-bit-A7-processor-offers-zero-benefit-according-to-Qualcomm_id47889

The good thing about all this negative publicity is that the 820 or the 821 or 830 or whatever they call next years SD810 is going to be ice cold cool as a cucumber because they are going to overcompensate and make something crazy cool. Lol

61 degrees is insane!

Those are internal temperatures of device not surface...just to test on my S801 device...I recorded 3 mins of 4k video...and guess what...cpuz reported 60 degree temperature...though it fell down quickly to ~45 and settled at 37 degrees after phone was idle for few mins.
