Question Has heating issue of this phone been fixed?

[stebrick]

I'm considering whether to buy this phone because how compact and elegant it is.

Thing is the heating issue I've heard of is holding me back. I've heard that the heating issue of Zenfone 8 has been fixed over the last 2 updates but I'm not quite sure about it. Can anyone confirm this? Does intense use (such as 4k video shooting or gaming) make it very hot?

And I wonder, in case it has been fixed, is the Snapdragon 888 CPU performance still the same? I'm worrying that Asus might have lower the CPU frequency or such so that the CPU generates less heat...

Hey,

Intense gaming and 4k video recording will still make the phone hot. After several minutes of 4k recording camera app will close because of overheating.

What? Maybe in Marrakesch that's true. I just did 5min 8k recording to check that nonsense statement. The phone got warm under the camera. Did not close nor did it give any warning.

Are there any phones that do not get hot during intense gaming??

I am using the provided case and the warmth is there but nothing untouchable nor risky.

I assume it depends where you live. In very hot countries you may get the warning that's it's getting hot.

In Munich, Germany which is not a "hot" country.

Nonsense? Not sure why you have that attitude but there are multiple threads on Zentalk forums about this issue.

Example 1: https://zentalk.asus.com/en/discussion/51884/shut-down-camera-overheating#latest


Example 2: https://zentalk.asus.com/en/discussion/49295/heating-issues-asus-zenfone-8#latest

Which says: "I am barely able to record 6 minutes of 4k 60 fps before the camera app shuts down. And mind you, this happens at an ambient temperature of about 29 °C, not 35. "

There is probably more but I didn't want to waste more time into it


I own and like the phone but the thermals are not the best and I just have said objectively what is the situation right now. Many other phones with the SD888 chipset are suffering from the same issues

So you live in the same climate as I do. My phone gave me a warning on recording once, when in direct sunlight at around 34C. It has been after around 15min of recording and cooling it in shade or water instantly allowed me to record more.

You say that the camera closes after few minutes of recording. So this happens to you often? Not in a forum - how many times did you have it?

I own flagship phones (LG, Huawei, Asus) since many years and they all get warm under some conditions. Never had any issues because of that.

So it happened to me 3 times and I switched the video recording to FHD 60fps after that.

As I said, I really like the phone, for my usage it is really good and I am sacrificing the thermals for the small form factor and performance. I anyway rarely record videos in general, so I am not at a loss.

For comparison on my previous pixel 3 during summer when the phone is in the car under direct sunlight and android auto is connected I would get the "phone is getting hot" once or twice a year. With the Zenfone 8 it never happened and it even almost doesn't get hot at all under the same circumstances, probably due to a more powerful SoC. But it does get pretty warm during gaming, I think without a case it would be impossible to hold the phone

I have the phone since August 28. Had heating issues until the update on September 3rd. Never since then.

Think carefully about buying this phone. I had a problem with a dying phone and it just came back om repair yesterday. It works, but the ASUS support leaves a lot to be desired. It heats up similarly like before, but what is disturbing only in one place - next to the camera. Previously, heat was distributed over the entire surface of device. Next thing, on sides of the back, you can see that the phone was opened. Previously the color at the edges was uniformly black, now the edges are kind of transparent and there are dust spots underneath them. Premium phone ... please ... my phone is not looking good anymore just because the manufacturer made a mistake at the production stage and it had to be repaired .... and something that annoyed me, when I was looking at the phone, I noticed that a few small particles of dust had fallen under the glass with the cameras. They are not too big to create problems with the pictures, but they are there and you can see them. I am slightly disappointed that the phone returned from an authorized service with something like that.

I have the phone about two months now, normal heat during random bit heavy tasks.
It heats a bit while playing PUBG in highest graphic setting but nothing crazy, you can play full hour with slight heat, I point fan to my phone and hands all ok.
After installing LinageOS I keep battery saver on all the time and phone doesn't heat and battery last all day long, got about 8 hours of display time (but didn't play any game all casual apps/shopping reading and music, some YouTube).
Seems like the 888 chip got more power than needed, I wish Asus make same compact phone with Dimensity or 7xx chips, that would more suits the type of people uses this phone, I think.
