Z5 heat problem with simple apps

Hello,

I've been using the z5 now for a little bit more than half a year and even as I write this review, my phone stays very well heated...
I am literally just typing a text and the battery heats up like I am playing some 3d application.
I hoped that the nougat update would improve the battery performance but so far I don't see that happening.

Simple things like using chrome and typing messages, causes the mobile to heat up and freeze apps up completely.

I mean why is that happening?
Isn't there some QA test that should have detected this before the release?

Either the energy management is completely messed and no one bothered to tell their supervisor or the phone can't handle more than calls and sms.
There must be a way to improve the power management for this series.
And please don't tell me that a new series will be better. I bought this phone just 6 months ago for 430€, so I expect at least some improvements from Sony to fix this issue either by adding a better process handler which limits the CPU to less power when doing low performance tasks like texting.

A normal Z5 would not heat on typing or browsing, I have my own Z5 and even when playing games it heats slightly. What I'm suggesting is to backup using Xperia Companion, then perform a software repair using Xperia Companion.

This will do a clean installation of the latest firmware and will also wipe your internal memory. Follow the steps given in the blue link, do not connect your phone until prompted to press volume down while plugging USB cable.
