Xperia Z4 heat_2The Sony Xperia Z4 was launched into Japan earlier today and already there are numerous reports of people complaining about heat issues for the handset. Below is a selection of statements on Twitter where people talk about how hot the handset can get. Users have been taking to forums and blog sites to document the temperatures of their devices and how well the handset does in benchmarks, trying to get a sense of the throttling taking place.

Retail shops in Japan are doing their best to warn people about the heating issues relating to the Snapdragon 810 chipset. The notice you see further down was placed in a shop and recommends users who plan to purchase a phone using the Snapdragon 810 chipset to ensure they periodically power off their handset, power off the handset during charging and make regular backups.

None of this is great marketing for Qualcomm and Sony, but the news is hardly a surprise given all we have heard about the Snapdragon 810 chipset. Whichever way you look at it, the Snapdragon 810 chip appears to have thermal issues and we hope Sony can find a way to ensure it does not impact the daily user experience, especially as the global Xperia Z3+ launch nears.
