Overheating even after update

[DerKrieger]

So i bought this phoen 10 days ago. It surpirised me  that only after 4-5 minutes of using it it became exageratly hot. So 3 days ago i updated the o.s. but the problem didn't go away. I had smartphones even from theyr begining and never encountered such a problem that escalades so fast . I mean i never get the passed the 5 minutes video recording time because the camera app. shotsdownd due to overheating. same goes for data connection and i don't even want to talk about gaming o better yet gaming online( i am a Hearthstone fan and i never got to play more than a game due to overheating). The phone becomes unbearably hot that I cannot hold it in my hand and i close whatever i do because of the fear of damaging it permanently. I understand that this is a waterproof phone Sony but please don't make us use it all the time submerged. Hope u solve this problem soon.

Settings > power management > battery > which apps are using up the battery, it could be play services, do you have an antivirus app or taskillers?

[DerKrieger]

The most battery goes to the display, atenna and so on. Play services only covers 9% of the consumption. I only have the antivirus that was preinstalled and no taskillers. As i said the phone is new and i have 4 aps installed one of which is a game and the rest are activation dependent not background functionality.

This is what I would do 

Repair the phone with PCC > uninstall any preinstalled antivirus apps > restart the phone > play store > settings > uncheck auto update > restart the phone > report back in 4-6 hours.

Kinda weird, I live at tropical country, and this July the temperature is reach 34 celcius degree. I'm using Xperia M4 Aqua to take pictures on the beach at miday for a hours. I don't have overheat problem, although if I look into CPU-Z, the internal hardware sensor reach 60 celcius degree. I hope you get solved this problem. Cheers.

And 60 Celsius is ok for a plastic phone? How long before all that heat damages the nearby pieces? Is not ok is a fault in the Snapdragon 600 series that needs to be repaired with an update.

Yes, 60 degree Celcius is hot, if the sensor are accurate. I have Xperia SP, CPU-Z detected only around 50 degree celcius maximum, but when I touched it's warmer than Xperia M4 Aqua. I also notice after update to 26.1.A.2.99 the high speed quad core part is never goes below 960 MHz when idle.

I have purchased M4 last night and it is messing giving heat upto 70% while charging and downloading something from play store, I already updated but issue still exist, This is very disappointing, Because I can't talk use my phone, Sony Kindly solve this issue ASAP.

Hi Qaisarshah, welcome to the community!

Are you using the phone while it is charging? If so, what are you doing on the phone? 

You could try running a software repair on the handset with PC Companion to see if that helps, you can back up your phone first by clicking Start under Backup and restore and then when that finishes go to Start under Support Zone > phone/tablet update > repair my phone/tablet > continue to follow on screen insctructions). If this doesn't help, you can then contact your local Xperia Customer Care team.
