Japanese giant announces software update to alleviate processor overheating on Xperia smartphones

The Xperia Z3+ and Xperia Z4 have officially joined the list of smartphones suffering from overheating problems due to the Snapdragon 810 SoC. Owners in Japan were the first to report and complain about the problem to the point where retailers began warning new customers before purchasing. Additionally, certain games and photo applications would automatically close without notice.

Dutch website gsminfo.nl has requested an official response from Sony and the Japanese manufacturer has now confirmed the overheating issues. The self-closing apps are apparently also tied directly to the overheating processor. Users can expect a software update in the near future that will likely throttle processing power to lower heat production. The reduced processing power should be barely noticeable during day-to-day activities as we have observed in the similarly-equipped HTC One M9. Instead, the main overheating culprit is more specifically the integrated Adreno 430 GPU, so demanding games may see a small drop in performance after the hotfix.

Snapdragon 810 SoCs have generally been known to overheat in the past. The fact that Sony launched its flagship Xperia smartphones with such vital issues overlooked has led to many disappointed customers. The Z3+ is currently slated for a July launch in Germany, so we will definitely pay close attention to any potential temperature or throttling issues in our inevitable review.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
