Sony Xperia Z5 Compact overheating issues reported: UPDATED

#

Sony recently announced its new Xperia Z5 flagship along with the Z5 Premium and Z5 Compact. Some were a little surprised that they all use the Snapdragon 810 chipset, which has previously been the source of some widely documented overheating problems. Now it seems that the company might regret this choice, as Sony Xperia Z5 Compact overheating issues are being reported.

Back in June we told of problems with some units of the Sony Xperia Z4 overheating. This also uses the Snapdragon 810 octa-core processor and some retailers were alerting customers about heating issues with the handset. The same thing happened with the Sony Xperia Z3+, also powered by the Snapdragon 810, and we’ve seen some manufacturers turn their back on the 810 to the Snapdragon 808 hexa-core CPU instead. For example the recently announced LG V10 packs the Snapdragon 808 chipset, as does the upcoming BlackBerry Priv.

It looks as though Sony thought they might have solved any problems with the Snapdragon 810 though, as was shown in a recent teardown of the Sony Xperia Z5 Premium. This showed dual heat pipes had been used as well as thermal paste being applied on the chip in order to prevent rising temperatures. It would make sense that they did the same to the standard Xperia Z5 and Sony Xperia Z5 Compact, but if so it doesn’t seem that this measure has worked.

The Xperia Z5 Compact is the subject of reports from China saying that the device is running hot. It appears that when it begins getting too hot the screen gets sluggish and causes a problem with registering touch input. In fact some users report that the issue is severe enough that sometimes the handset doesn’t register touches at all. The reports also mention that some owners of the device are attempting to solve the problem by rebooting the Z5 Compact, but find this doesn’t always work.

Sony might be able to alleviate this with an update to lower the temperatures, but this would involve throttling the chipset. At the moment though this could be a way of resolving the issue, at least for the short term. One owner of the Sony Xperia Z5 Compact has produced a video showing the issues he is encountering with his handset (see update).

At the moment it’s not clear whether this is a widespread issue or involves only a limited amount of units, but it might make some buyers about to order one think again. What are your thoughts on the overheating issues being reported for the Sony Xperia Z5 Compact? Were you surprised that the company went for the Snapdragon 810 chipset again?

UPDATE: We have removed the video from this article as it was brought to our attention that the title had changed. This implied that it was wrongly used by one of the sources to suggest overheating rather than a simple touch issue.

    I have a Z5 in my hands right now. Although it does get warm, it doesn’t overheat. Not in regular use at least.

      I think maybe the z5 is bigger so it’s better at keeping the temperature in check. And Z5 compact teardown would be needed to make sure they used the paste and the pipes in there too (maybe too small and also the lower price has to come from somewhere), it would be better than wild guess.

        Take a look at the title of the video again. It says PhoneArena is lying. There is no overheating present. That was a touch issue.

    I’ll take the same stance I took before the phone came out… I’ll wait until a big enough sample size is available to make an accurate decision on whether or not it will overheat. So far I have only seen 2 claims, and since this has been released in quite a few markets already – 2 seems to be a very small number and within margin for error.

      Take a look again and see the title of the video. It says that PhoneArena is lying. PhoneArena was probably paid by Samsung to bash other brands and stop them from rising, especially ones that are pushing new innovations like Sony.

    810 is a failure just accept it,LG knew this & its the main reason why they went the older low end 808 for their latest device,V10. Remember the 810 is a rushed project by Qualcomm in order to catch up with the Octa/64bit soc era because their CEO claim that wasn’t necessary in mobile.

    Damn phonearena lying, there’s no overheating issues, that’s just a device with a faulty touch screen, it was replaced with aa perfectly working one.

  5. Francis.F says:

    Glad I clicked the video it has noting to do with over heating its just a bad touch responds which the user replaced No Over heating issues

  6. Mike says:

    Overheating? Dunk it in ice-cold water. 🙂
    Kidding aside, I’ll believe this when every single z5 compact user complains about overheating.

    Just upgraded from Z3C to Z5C… Phone really warms up fast during the downloading of apps… When i woke up this morning, did a few minutes of browsing, phone warms up again really quick… I really hope Sony would have a software fix to this heating problem… Otherwise i would regret the upgrade from Z3C… The Z3C is an awesome compact phone.. Battery life is awesome.. My Z5C is heating up quite hot now as I’m typing this comment… 😢
