You're burning up your battery. Time is of the essence, resolve this issue fast. Shutdown the phone if it gets too hot!!!
Auto thermal shutdown may not protect the display/mobo especially if in hot ambient temperatures, in direct sunlight, or when charging.
Keep brightness at 50% or less.
Factory reset.
If that fails...
Find the apks or/and services causing to high drain.
If that fails, return the device.

The clock is ticking, Mr Wick tic-tok... 💣

This is a serious problem. I took some photos and videos (4k and slowmotion) while standing in the sun. Outside temperature was about 23°C (73°F). After about 5 minutes I got an overheat message.

An app that I installed earlier registered an internal temperature of 40.5°c. It felt really hot to (while in a bumper case).

After I put the phone on a granite kitchen table it cooled down in about 10 minutes.

It is serious. Turn off the phone when it feels very warm before it goes over temperature.
Using a AMOLED display in direct sunlight is never a good plan. Limit it to seconds of use.

Just another aggravating issue with this phone. Some are having boot loops of a sort also! What is wrong with these companies? Can they not produce a decent product anymore? 1300.00 and it's junk???????????

I am getting overheating as well, a little warm most of the time I use the phone.

Definitely was the 120hz display turned on. Less warm when the 60.
When using the wireless charger.
Anytime I use the cameras.

I am on the latest update as well.

Hm, very intriguing issue with $1300 flagship smartphone from such a respectable brand. I had similar problem with Xperia 1 II in several occasions. And... I think I know what's the problem (not bloody hot SD888 as you might suggest!). Please have a good look at dissasembly video:
Then compare it with $390 LG V60 ThinQ disassembly video from the same guy. Spot the difference! And it is - missing cooling system on Xperia 1 II / 1 III whereas LG V60 has quite big copper vapour chamber! Maybe that's why my LG V60 never gets really hot. So the question is ... WTF are you doing SONY?!

Well, I just sent back my first Pixel - 5A - for overheating. I have been watching the 1 iii and the 5 iii as a possible purchase...but I am turned off by the dedicated assistant button that might possibly be remappable... but for sure I will NOT buy either of these mark 3 phones if they overheat! Makes me sick just how badly most new phones are functioning.

Yeah same, it seems to turn off randomly when using the cameras and when 120HZ screen is on.
I think it's the case for warranty replacement or even return if possible. This is one of the reason why I don't buy expensive brand new phones parallel imported (not officially sold in my country). Just because it means no proper warranty, no service, no nothing.

My Xperia 1 III is getting extremely hot even when taking photos (only 2-3) then get message about hot temperature and apps shutting down.

I use Streamlabs mostly (sometimes Prism) to broadcast to YouTube, foundthe phone almost useless! Overheating in seconds from start of s stream! I'm using my old Samsung Note 10 again as Sony wasn't simply useful.

Now I found a solution to it (sorry solution is too big word)
- I've turned "object tracking" off in camera
- I've turned autofocus on in camera
- I've turned 120hz off

Today we had hot day here in UK (27 Celcius ) I did my tests.

Streamlabs at 1080p , 7000kbps , 30fps run outdoor for about an hour smoothly. Connected to charger started to overheat.
Not to mention that tethering makes it hot quickly (so with Samsung).

Prism at 1080p 60fps run smoothly for couple of minutes and then crashed.
Didn't connect the charger.

I use Streamlabs to transmit 5-6 hours of stream into YouTube using mobile network in most if the times and whilst driving (so changing stations constantly)

I found that using WiFi it doesn't get as hot.

Also charging makes it very hot - SONY advertised it as able to by powered directly by a charger without charging battery, how and where do I find that option?
Is it available using car charger with quick charge 3.0?

I like the phone , like the shape , size and feel to it. Camera is OK (I own Sony a6500 )

Hate the fact of poor selfie camera in such expensive phone (I do live streams using selfie cam too)

Right I've ordered a return of my phone and have 30 days to send it back what alternatives do I have? Really like the SONY if it wasn't overheating I'd love it. Is there a solution to it? Cooler anything?

The things I like about the phone are:
*shape and overall feel in hand
*Cameras are ok don't really see if they great quality or not will still use my a6500 camera.
*Like the fact that can use sd card
*Love finger print reader in power button and seperate camera button
*like the fact that there's no rounded edges - hate them in my Samsung Note

I blame my problems with overheating by poorly made apps not the phone itself and not sure changing the phone will change it.

What are the options should I consider? Samsung S21 Ultra ? iPhone 12,13?

I'm a SONY fan and had many if their phones and that's why I'm looking for a solution otherwise would send it back straight away...

Can anyone help me with my problem?
Many thanks
Bart

Unfortunately greedy sony didn't provide any cooling solution to mark 3... Check disassembly videos, there is no any cooling solution at all, like you will find in asus - small vapor chamber etc. Literally nothing!

They knew snap 888 is overheating. They must have tested this device before releasing it, isn't it?

But no, still didn't apply any cooling solution. And that's a big shame and huge problem of this device.

Not sure if qualcomm provide any updated drivers to assess this problem or not. Or if sony will try to fix it. So far they did nothing and still it overheats. Mine too and you are right by saying that on 3G/5G it is hotter than on wifi.

I wonder how they can market battery as capable and better for 3 years with such hot device. Temperature of course has huge negative impact on battery longevity.

Sad but true :(

I'm quite shocked! Thanks for the info about disassembly videos...

I'm thinking if getting a cooler which you attach to the body.

What I forgot to mention that cameras itself (the lenses) don't get that hot is the area under them and closer to the centre. So must be processor and lack of cooling system.

Not sure what to do...
We have a hot weather now so I will test it intensively (if I was a Sony tester I'd never allow for the phone to be released like this).

Heating problems is why I keep saying that for any SOC/CPU/GPU manufacturer to keep upping the speeds of these things is STUPID! I can virtually guarantee that from now on every new CPU produced by all OEM's is going to overheat! Have you ever walked into a data center, with hundreds of servers running? You have to wear ear protection because the roar of all the internal cooling fans is deafening!
So then "we" attempt to put similar CPU's inside a device the size of a small remote control WITHOUT a fan and wonder why it overheats? There are only so many ways to keep the phone(s) cool. Use them while frozen solid in a block of ice, or better yet, stop running so many CPU/GPU intensive apps all at the same time. It's simple thermodynamics at work here. The more you have running at the same time, the harder the SOC needs to work, the hotter it is going to run. Another solution, that is literally unacceptable to most people, is to code in a lowering of the speed of the SOC. If this needs to be done then it becomes very clear that building a new, faster SOC every year is STUPID!

One more thing... I've heard that Xperia 1III is capable of powering the phone directly without battery charging to lower the heat...Does anyone know how do I turn this future on?

This is applicable with the game enhancer. You can add some apps there and when you open it, you can enable HS power control. Also sony just release a new firmware that answer you with this issue.. you can check my video

Thanks a lot , tomorrow I will be testing - doing long live stream on YouTube using Streamlabs, I always keep my phone under charger as I drive HGV sometimes for 3-4hrs non stop so battery would die.
It also going to be hot day here in UK and having the phone close to windscreen won't help - I know I shouldn't complain about overheating in such circumstances but my phone overheats even when taking photos although I have a feeling that after last system update its looking better , also as I mentioned before switching off object tracking has improved how smooth camera works using Streamlabs and Prism.
I'm considering buying a cooler for my phone too.
I will post my report tomorrow of how it went.

Many thanks
Have to sit at the outlet all the time? or how will this happen?
I found the future now in Game Enhancer app, you can power it directly. Not sure how it will perform yet. Tomorrow will send my report.
I often run streaming app in the background and not sure if Game Enhancer will work that way. I run nav app (Sygic Truck).

    Heat problem has gone down significantly for me after the latest update yesterday. Usually the phone got really warm even with me just browsing using Chrome or going through Facebook. Now even when playing ROK or Mobile Legends it doesn't get that warm.
    I'm not complaining because I certainly do not want my phone to overheat...but it makes you wonder what Sony did to accomplish this? In my years with IT tech I know that there are only three ways to make a CPU run cooler...either you lessen the load by running fewer apps per CPU cycle...or you spin up a really good cooling fan (even water cooled system) OR...or, you slow the CPU! Now which one do you think Sony is doing? Personally I don't care if Sony slows the CPU as I think that all fairly new ones are way overkill anyway. As long as everything still runs good I will be happy. Mine should arrive Friday!
