Overheating z1 compact after KITKAT

[Babar1]

Folks, 

I am so frustrated with Sony. 

JB was working more than well, that they asked us to move to kitkat 

Now the very last version has transformed my mobile into a mobile oven. 

It is so hot that I am afraid to leave it on I am afraid to damage the battery... 

Anyone experience the same issue with the latest firmware? 

Build xxx. 757

Thanks for your help

You should not be experiencing overheating from this update. Do you have any issues with battery life that has gone along with the heating as this could indicate a problematic application?

Had exact the same problem,
Formatting the extended sd card solved the heating.

Try it by frist ejecting your sd....

for some reason it was not working well with KK, after uninstalling it everything when back to normal

No problem, glad it is sorted. It would be worth checking the Playstore for updates to any and all of the installed apps in this circumstance just to preempt any other issues.

I too have had problems with extreme overheating and phone "locking itself up" after the 4.4.4 update,the phone was almost too hot to touch!...not sure I can put it down to instagram as it is an app I don't use! O2 have sent the phone for an expert to look at as the O2 guru looked very perplexed!...shame as I have been very happy with it up until this!

Hi guys,

My phone's been noticably more "toasty" since 4.4, how do I find out which app/s are causing the bother?

My apps are all updated daily btw.

I think this should be a serious concern for Sony. I experienced the same thing with Instamag, hence had to remove the app to stop the overheating.

I usually check for apps that drain the battery (and are a prime suspect for overheating) in the Power Settings:

Settings > Power management > Battery usage

The apps showing on top are consuming the most power.

I do have the suspicion that when you are charging the phone, the readings are not accurate.

I get the best results by disconnecting the charger, let it run for a minute and check.

I have a problem with Google+ and the Picasa uploader.

Once I kick them from the cache, power consumption gets back to normal for me.

You can kick them from the cache here:

Settings > Apps > Swipe to Running > Click on Show cached process > scroll to the app and click on it to stop it

I have the suspicion there is a background task that goes through my photos and is choking on the close to 1000 photos I have on my SD card.

Right, my phone was fully charged when I left home this morning at 7:30 and as I write this (11:05) its showing 42%, which isn't too bad I guess because I've used the phone quite a bit today but earlier I thought the phone was going to catch fire! It was so hot that it was almost to hot to handle... this can't be good for the phone or me can it

In Power Management > Battery Usage was showing Android System as using 47% battery! I've always had the screen showing as using the most battery at on or around 20%. Something was obviously not right? I've just checked and Android System is now down to 33% (its still never been higher than the screen %) and the phone is cool to the touch.

Any ideas?
