Sony comments on Xperia Z3+ overheating issues
July 01, 2025
Comments around the thermal management have been plaguingQualcomm’s new Snapdragon 810chipset ever since it was announced and these issues have passed through to handsets running the next-generation processor. Themetal-clad HTCOne M9ran hot on intensive tasks and theSony Xperia Z4andXperia Z3+have also suffered from overheating with the processor.
Qualcomm haspreviously come out and called reports of the overheating issues ‘rubbish’while Japanese carrier NTT DoCoMo has putadvisory warnings on handsetsrunning the processor. HTChas releasedan update for the One M9and Sony has now finally responded to the heating issues that are plaguing its newest flagships.
Dutch websiteGSMinfo.nlfound that theirXperia Z3+sample would overheat frequently and apps such as the camera and other games would automatically close due to overheating. Responding to these issues, a statement from Sony read:
Sony then went on to confirm that, likeHTC, it would be releasing a software update later this summer to address the thermal issue but there are worries that Sony will throttle the processor in order to keep the heating issues to a minimum. Until the update rolls out, Sony says that customers who are unhappy with the handset’s thermal management can contact its service centre in their country to discuss their options.
The Xperia Z3+ is essentially the same handset as the Xperia Z4 but sold under the Xperia Z3 Plus name in markets outside of Japan. Thereason for the name changeis that themodest upgrades offered by the Xperia Z4– which include the advanced 64-bit octa-core processor, higher LTE speeds and a lighter, thinner build – are enough to be worthy of a new model number in Japan but not so in other markets.
The overheating issues in the Snapdragon 810 chipset may have resulted in Samsung switching to theExynos 7420in itsGalaxy S6andGalaxy S6 Edgeflagships this year but others have still stuck byQualcomm. LGworked closely with Qualcommto optimise theSnapdragon 808for itsG4 flagshipwhile Google is working with Qualcomm on aSnapdragon 810-powered Project Tango smartphone.

The jury’s out however on whether Qualcomm and its OEM partners can fix the thermal issues without impacting on the performance and with itsSnapdragon 820 chipsetnot far away, Qualcomm will be hoping to rid itself of the very-public 810 thermal issues.
