But article suggests they just lowered the clocks of cpu / gpu with newest update. Otherwise what else they could do???

What is your experience on this update? Is everything smooth? Scrolling / animations? How about when 120Hz is on?

Gaming performance decreased much?
Overall speed of the device?

And most importantly: any difference in battery life? It is so bad right now :(

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!

So far no changes with the performance like I mention in the video, no lags at all.. using 120hz straight and battery life improved..

No changes in performance. Still runs very smoothly. Battery life is the same so so lol. 4 1/2 hrs SOT only for me.

I think if you take SD 855/855+, SD 865 and SD 888 based flagship smartphones you won't distinguish them from each other in real life in 95% of games and apps. Only synthetic benchmarks show the difference. So my guess that Xperia 1 III with the latest update will get less marks in tests for above mentioned reasons (underclocking / undervolting). I don't believe in Sony's programmers magic - Google stole all of them :).

If fairness I do feel the difference in speed of opening apps vs my Note 20 Ultra Snapdragon variant. That's the first thing I noticed when I got the 1 lll. The apps open faster. Might just be me though lol

It's rather exitement impression, the way that Android skin operates / tweaked (Samsung's OneUI isn't the fastest in the world) and other small things than raw chipset performance difference. I feel the same way towards my snow white Galaxy S21 Snapdragon - it really feels blazing fast, the fastest phone I ever had etc. But... when I grab my old Pixel 4 again, I realize that it's rather false impression trick by new, shiny, sleek phone.

Have to sit at the outlet all the time? or how will this happen?
I am experimenting here. I added the MAPS app to the Game Enhancer. Then when you open the MAPS app there will be a floating icon (that can be switched to a pull down menu) where you will need to click on "game Mode" and in here is where you turn on H.S. power control.

According to what is supposed to happen you should be able to plug the phone into your car charger and it will power the phone while running the MAPS app and not charge the battery. This should lower the heating on the phone and spare the battery from being used.

I have the Hong Kong version, during the purchase, we were told to do a reset to the phone, it should sort out the problem, not sure if it's true, but I have not receive any over heating.

I received my phone 3 days ago. During set-up I did 2 firmware updates. Sincerely, I don't know how it was earlier, but now the phone still goes warm when using camera and other apps (sometimes even when I watch YT videos).

Right guys, thanks for all your help, Sony is currently packed up in the bag and waiting to be dropped at the post office... Yes I'm returning it...

After a big excitement I'm very dusapionted with the phone. Being a Sony fan it's even harder for me to return it.

The issues of experienced with the phone:
-when live streaming using Streamlabs phone extremely overheats and slows the stream dramatically, I need my hotspot to be on at the same time which is being turned off.
- during the stream power consumption is greater even using quick charge 3.0 charger in 24v socket with phones screen off
- experienced lost GPS signal when using Google maps (might be just another calibration)
- launching Streamlabs and Sygic Truck sat nav on split screen freezes the phone due to heat.

I'm now back to my Samsung Note 10 and as its getting hot too it doesn't switch off hotspot, stream goes smoothly, charges with the screen on using same quick charge 3.0 charger.

OK, any suggestions what could I get instead? S21 Ultra too big for me, thinking of an iPhone 13 Pro as it has excellent cameras (both)

Cheers
Bart

    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.

    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?!
