Please share overheating related experience & issues, or lack of it you have had with newer Xperia 1 V model.
Any rigorous and real-life testing data will also be highly appreciated.

In short, does it overheat? And if so, to what extent?

Thanks 🔥
it doesn't have any overheat message anymore... according to this review and many other reviews i watched these past couple weeks...

Yeah, I also watched couple of reviews but I wanted to get the info from someone who actually uses the phone daily.

Not having a overheat message displayed is a good start but by no means solves issue mk IV had, basically it was always hot, so I'm curious if mk V is really up to the task.

Thank for the link anyway

actually the issue was not in the phone itself but rather the SD Gen1 had overheating issues across all devices but in Xperia was more because Sony didn't have the best heat dissipation hardware but as for the Xperia 1 V it's another story ( they solved it)... so, my assumption is that the phone won't get the overheat message anymore and in addition to that the SD Gen2 doesn't have the same overheat issue the pervious gen has

Cooling concept is still as bad as before. SoC just doesn't draw as much....

There are phones with SD8Gen2 and WAY better results.

BUT they do claim that there is no overheating issue while filming.

Now, the good news.

First, the Xperia 1 V never became hot, warm - yes, but never uncomfortably hot.

Second, there is no display throttling; the screen refresh rate remained at 120Hz even after prolonged benchmark testing.

And third, the most important news is no more camera overheating! It was incredibly awful for a cameraphone to overheat after just 5 minutes of 4K video recording (Xperia 1 IV, we're looking at you), but that's a thing of the past. The Xperia 1 V is not even warm after shooting for 30mins in 4K, which is excellent news.

The camera overheating warnings are still there in the menus for some features, but we never experienced them, and we hope you will never do, as well.

We played a game for half an hour, too, and the Xperia 1 V was not hot and did not throttle, not obviously, at least. That's why we think most gamers and photographers alike would be happy with the improved thermals even if this was not reflected in the synthetic tests.

you just need the phone rooted and lower the clock speed to prevent overheat.. save battery too

Underclocking and any kind of battery savings together is a myth as well as snake oil, considering that the CPU core(s) have to spend a longer time out of idle for getting the same thing done that could be done at a faster pace on a higher frequency.

In theory maybe, but in reality with lower frequency you can prevent CPU from throttling which will result higher average performance ;)
Just look at the test results above and compare it with my tweaked 1IV which is supposed to be worse. For longer tests visit "thermal confirm mod" topic in 1 iv forum.

No Issues with mine apart from its quite hot whilst charging. The phone is a breath of fresh air though in my hoineymoon period!
 
Overall it is vetter than mark IV because of two reasons:
1. Cpu -snapdragon 8 gen 2 overheats much less than gen1
2. Dramatic throttle made by sony. Yes sony squashes cpu and gpu frequency aggressively which impacts performance. While it has not that much impact on the apps or browsing itself it does have it for gaming. I hope sony reads it, frequences for gpu are too low, tests proved we are losing 55% of performance... While gaming and its too hot frequency also drops from 120hz to 60...

Overall they added 60 or 70% more film inside and that's it? That's their hardware solution at this price? It should be some vapor chamber or liquid metal as we have in ps5 or pc... Tests and comparisons also shows other brands again are dealing with it much better. Newest Shamesung does not drop frequency so much while being cooler at the same time, so it's definitely possible.

Hardware in mark V they will not change for sure. What they could do to prevent this dramatic frequency drop is to do some small undervolting via update.

Hope they will do this.
 
I have device since 2 days only and it was extremely hot for me only at the beginning. You know where all apps are installing, os update installing at the same time, google setup etc.
At this time and it was after charging, not during, it was extremely hot. Let's see how ot will be when I use it more.

Does anyone know if using their original cover helps with heating dissipation or it is worse for the phone?

    Based on his testing, it seems much improved over the Xperia 1 IV
