The Qualcomm Snapdragon 810 processor has been the subject of many allegations of overheating, and while Qualcomm has refuted these claims and updated their chipset, it would appear that some devices are still reporting overheating. The most recent reports centre around the Sony Xperia Z5 Compact, the smallest of the Xperia Z5 smartphones that Sony announced at IFA 2015, and despite Sony taking every precaution with thermal paste and heat pipes, it appears that shrinking the size of the device has done no favours to the heat dissipation.

The reports originate from China and allege that several Xperia Z5 Compact handsets are overheating so much that touch and performance is severely affected, and in extreme cases, the touchscreen will stop working entirely. We’ll have to see whether Sony responds with a fix or not, or exactly how widespread the issue is, but it would appear that no matter how much Qualcomm thinks it’s fixed its Snapdragon 810, a combination of its tendency to heat up and a smaller device still results in a non-ideal situation.

What do you think about reports that the Sony Xperia Z5 Compact is overheating? Let us know your thoughts in the comments below.

    I watched an iPhone 6 Plus get thrown across a room earlier today and the girl that threw it saying “Owwww, it burned me”. All phones can overheat. Hell, people are getting 3rd degree burns from a particular brand of phone regularly when they explode during carriage rides and whatnot.

    Your story is what is called “confirmation bias”. You had an idea in your head ahead of time, and you found information to support your bias.

      Perhaps, but there sure are a lot of reports of this particular chipset is overheating. Not denying that all smartphones can overheat though.

        Also, there’s no proof about anything for the Z5C … Every touch problems that’s been post on internet these recent days are in fact a problem of screen, not overheating.
        Every android website are copying/pasting without checking anything …

          A lot of tech journalists simply aren’t….. degreed engineers. I know, that’s shocking right. They are trained journalists. And a lot of the time their job is simply to relay information that they’ve been told is gospel. Also, a lot of the time their editors tell them what they are going to write about, then change it around on them and they have no say in it. That being said…

          The second a product threatens Apple, you will see stories magically appear to trash that product. It happened to Lenovo. The day they passed Apple on PC profits, there were magically 50 stories about malware in Lenovo computers. Turned out to be utter lies, but it happened. So you can’t trust any story about any product that competes with Apple. Especially Sony’s little phone that makes the iPhone look exactly like the midrange garbage it is.

        Yeah, I’m not really giving you hell for it. It’s an easy thing to do. I do it.

    • Adobo King

      Good point. This is why I deleting this rumorsite from my RSS. So much junk and bias!

      • Scott Wilson

        That’s a little too far. I’m not giving him crap really. I do the same thing sometimes. So you do.

    I have my Z5 Compact for a week now and it did not get hot to the touch once. Sure it can get pretty warm while gaming, but never hot.

    • FILA

      where the hell are people buying these phones at????!!! Does it work with T-Mobile band 12

      • tj

        They are available in Japan and Europe. Most models should be compatible with all of t-mobile’s bands, but to be sure, check out this site you can look at the different models there and see which ones carry which bands. I want the full sized version really badly too, but I’ve seen a couple of less than flattering reviews of the camera for video and still images. Even though the sensor is better on paper, when you look at the side by side comparisons, the s6 does a much better job IMHO but it doesn’t have the expandable memory card slot, so i’m hoping that the camera comparisons I’ve seen are just due to the settings not being optimized on the z5. Fingers crossed. Either way, unless you have money burning a hole in your pocket and you don’t care about the warranty, I’d wait for an official north american release before buying this phone.

      Mine gets to 31ish degrees just browsing the phone w/o wifi or 4g switched on.

    The Snapdragon 810 is the reason I won’t get a flagship phone this year.
    Sure, there are flagships using the 808 chip, but then I feel like I’ve paid a premium price for a “lesser” product, no matter if its true or not, since I’d get a 6 core CPU instead of an 8 core.
    Not that it really matters in the daily life situation. It’s only in my head.
    But still… No upgrading for me unless one of my current phones dies, and if that happens, I’ll get something cheap while waiting for next years releases.

    • Stephen Yuen

      You could always get a Samsung device with the Exynos processor 😉

      • Daniél Lecoq

        True, true…

  • masi0

    I can bet no one of you confirmed that and you just copy and paste this gibberish

    I’ve been using the Z5C every day for more than a month now, and the only time it really warmed up was when I ran the 3DMark benchmark out of curiosity. Regular use, even when doing things like watching video, got it slightly warm but not to the point of being uncomfortable.

    I’m not sure how accurate the readings are, but I use an app called Battery Widget that purportedly reports battery temperature, and I’ve never seen it exceed 35°C so far. In any case, I’ve never been concerned about the temperature, in contrast to the Z1 Compact I’ve used for the two years prior, which did get pretty hot on occasion.
