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.

Dear Ms Sophia,

Problem is this that whenever I download a app or charge mobile it heat up till 70 degree C in the meantime sometimes I have to call so it's disappointing I will have to use hands-free to avoid ear damage due to immense heat, kindly do the needful and it's not the backup issue.

Your solution doesn't work. tried it myself and the overheating problem is still there.

How come you don't contact your local Xperia care in person?

Owing E2303 for a couple of days. Came with the letest firmware 26.1.A.2.99.

Well its performance is unacceptable for a handset using 615 soc.

Its antutu 26-27K score is almost on par with moto g 3rd gen 23-24K which carries the much slower 410 soc.

Tried a dozen brosers, all lag in scrolling and web page rendering is slower than my 2013 moto g!

Lag is everywhere except navigating in the UI. Even swithing to the previous app is laggy.

I saw a handset which did not had this firmware installed, scored 35K in antutu and was really running flawlessly, hooter than mine but usable. The performance i saw was the reason to buy it.

Now i am disapoinited and i can't take my money back...

PS. I have already done factory reset, nothing changed. The new forware in order to reduce heat reduces performance as well.
