xz2 high temperature

[tridious]

Hi, I have been using the phone for the past 2 days and realised that it heats up pretty quickly. It was particularly hot at the top part of the back of the phone, the area where the NFC logo is located. I did several "tests" to see how fast it heats up, and I made sure that the phone was cooled down before each try.

Firstly, I used the phone for browsing the internet for about 15mins and realised that the temperature(battery) has risen to 43 degrees celsius. Next, I tried using its camera and took several shots and after about 5 minutes of use, the temperature has also risen to 44.2 degrees and the a message was prompted stating something like "the temperature is too high! camera needs to turn off." I then tested the video recording in 4K resolution. The recording lasted for only about 3mins 40secs before the message was prompted, and the recording was not saved. The temperature rose to 44.5 degree celsius.

I understand that the automatic shut off of the camera was to prevent any hardware damage from the high temperature. However 15 mins of browsing and less than 5 minutes of 4k recording does not appear satisfactory from a user's point of view, especially after the device being touted as the best Sony has built. I hope that a software update can help mitigate this issue, as it will be a huge hindrance to the day to day usage if the issue remains. Does anyone else have the same issue?

I've seen that once with my Xperia Z1 and twice with my Xperia S, if you are running a lot of apps, or syncing quite a bit of accounts/services/apps and its a hot day and/or you have been using your phone for quite a bit of time it will get hotter and hotter so it is normal, now, this could also mean that you have an app running in the background that its creating this problem, restart your phone on safe mode and check again, if not you could re-install the latest update with SUS or PCC

Hi uliwooly, thanks for the suggestions. I upgraded from a Xperia S too, which had overheating issues too. I took your advice and re-updated the latest firmware, rebooted it in safe mode and retry. However, the same issues persist, the camera seems to last a bit longer but 4k recording still doesnt cross the 4 minute mark. Can anyone else give it a try and see if its a widespread occurence or maybe its just the handset i got. Thanks!

That's quite odd, where are you saving your videos? (SD card or Internal Storage)

[tridious]

i tried both, sd card before the reupdate and safe mode reboot and internal storage after.

When you store the videos on your Internal Storage, does the video stops at 4minutes? 

[tridious]

it stopped just before 4 minutes, about 3 minutes and 55 secs, just a slight improvement.
