The Sony Xperia Z5 Compact is apparently facing some overheating issues, and the Snapdragon 810 chipset is again considered the culprit.
The Qualcomm Snapdragon 810 64-bit processor is no doubt powerful, but overheating issues have been plaguing nearly every device it powered. By now it's no longer a secret that smartphones packing the Snapdragon 810 tend to overheat, but some OEMs have found various ways to prevent this from becoming an issue.
Others, meanwhile, have chosen to avoid the Snapdragon 810 altogether. Samsung, for instance, preferred to equip its flagships with Exynos chipsets, while some other OEMs opted for the Snapdragon 808 instead of the overheating 810.
Nevertheless, there are still plenty of OEMs that still relied on the Snapdragon 810 for their handsets, and most of them are now facing criticism and complaints of overheating issues.
Sony, meanwhile, equipped its top-notch Xperia 5 Premium with extra heat pipes and thermal paste on the processor so it wouldn't face overheating issues due to the Snapdragon 810, indicating that it was well aware of the situation. The extra heat pipes allow for the heat to dissipate more quickly and effectively so the device wouldn't overheat.
It remained unclear initially whether the smaller Xperia Z5 Compact had the same treatment to avoid the Snapdragon 810's issues, but it now seems that question has been answered.
The Xperia Z5 Compact is apparently overheating just like other smartphones that pack the Snapdragon 810 without other precautions to prevent it from running too hot. Owners of the latest compact flagship from Sony have started to complain that their phones are getting excessively hot, and this overheating could lead to other issues.
New reports out of China claim that the Xperia Z5 Compact gets so hot at times that the screen actually becomes either sluggish or completely unresponsive, unable to register touch input. A video of such an instance surfaced on MyDrivers, showing obvious issues with touch input on the Sony Xperia Z5 Compact. It remains unclear at this point, however, whether these touch issues are indeed related to overheating, as subsequent reports argue they may stem from other causes.
On the other hand, some Xperia Z5 Compact owners have reportedly been able to overcome the touch issues at least temporarily by throttling the chipset to lower the temperatures, albeit apparently this method didn't work for everyone.
It also remains unclear for now whether these overheating and touch issues affect only a small number of Xperia Z5 Compact units or whether the problems are more widespread. It's also worth pointing out the Xperia Z5 Compact has yet to reach more markets, including the U.S., which makes it even more difficult to determine how widespread the issues are.
