xperia z5 overheat?

[billking1]

When my z5 start the update to new version the temps are high.

30seconds after finish the os and apps update the cpuz sensors tsens_tz_sensor 2.3.4.5.6 was 64+celcius and it needs 30more seconds to cool down (30c)

The room temps are 22-23celcius

For the update my phone drain 9% of battery from 90%-81% and take more than 15mins.

After Marshmallow update installation is finished, apps will be optimized with the new software. The more apps you had installed the longer this process will take, leading to more battery consumption and more heat generation. Once optimization is finished, your phone performance will be back to normal.

After 8 month of use Xperia Z5 I regret that why I bought this heater. Those days everyone told me that don't buy Sony phones and now I can understand the reason of Sony losses in market. I paid over 520$ for a simple heater. It's ridiculous my phone battery percentage decrease even while it's connected to a UCH10 fast charger and I'm playing a online game. The temperature easily reach 57 degree so you feels burning skin. I did factory reset, repair, reduce display brightness to zero and etc. Nothing changed. Please never buy any sony phone. E6633. Android 6.0.1 build number 305. Seriously Do NOT buy Z5. Here is screen shots from cpu-z

Does anyone else find their Xperia z5 heats up excessively when your using it?

[MarlonUk1]

it depends on your usage,

1.) the device heats up during heavy usage like playing games 1-2 hours or more, 4k recording or using the AR and other camera apps, using the device for prolonged length of time. etc

2.) environment, thick cases

3.) after app installations , updates, software updates,

4.) using the phone while charging

only when it is doing something online and the reception is poor.

I earned new achievement last night. This smart heater reached 60 C degree. Marshmallow has reduced temperature but it ruined battery endurance. New screen shot:

Hey guys, I found out something weird! In Gsmarena and all other review sites they have wrote that Snapdragon 810 has 4*1.5 ghz A53 +4*2.0 ghz A57. But I checked couple times and CPU-Z shows my Cpu structure is 4*1.96 ghz A53 and 4*1.56 ghz A57. Their Clock is vice-versa. Maybe that's my phone gets too hot. Please check is it same for you!?!

It drives me crazy couple minutes ago This Heater reached 65c degree! It's crazy why they don't think about this problem! I uninstalled every application that I used less and nothing changed, please please please send them our user feedback. Something is not right about Z5 E6633. I have scared of use this phone because I think it might burning itself. Over 60 degree is not a joke. Just look at this screenshot:
