S21 Ultra overheating issues?

[Morty2264]

Not looking for a signal. I live in LA. Always a strong signal. Plus I use wifi calling when needed.

Okay, that's good to know! How does the phone fare when it's on the charger?

It charges fine.

It would be helpful if others could tell me how many degrees their cpu get up to when they're watching YouTube and playing with their phone for half an hour. Otherwise it's hard to tell whether my phone is acting normally.

I haven't noticed anything abnormal with heat with my S21U over my S20U. The phone for me that was really bad with overheating was the S7! I still remember walking out of the AT&T store with it brand new and the thing was nearly burning my hand! And I had two of them! Both overheated bad!

Same with my s7 edge

If you just got it and set it up, you can expect it get warm a little until settled in , if it's doing this past 5 to 7 days then I would put in safe mode to see if any 3rd party apps are causing this .

The problem is there's no way to have it measure cpu temp in safe mode. That's why it'd be helpful to get a comparison of other's screen on time.

Understand but you mentioned that it's pretty hot in the hand no? Also a temp gun like these are cheap

Yeah, I just ordered one.

But I watched YouTube and there's a guy who did a battery test that was fairly rigorous. I think the phone averaged about 32 degrees Celsius. The problem is he is just using an infrared censor on the screen, which isn't comparable to my cpu temp scanner.

Also what's weird is that YouTube doesn't seem to heat up the phone much, but other video sites make my phone burn up. Is there any reason for that?

I watch a lot of youtube videos and web browsing and I feel no overheating. To me it seems like when a long list of apps are updating is when it gets the warmest but nothing to cause concern. I think doing long UHD filming with stabilization on will be the true test.

I've use these type of temp gun in my field for surface temp and they are pretty good . See what happens.

I also notice that once it gets hot, like 40c+, it can take 20 mins to cool down to normal temp. I thought that was interesting.

Looks like a pretty big thread of over heating issues in the eu? It is a different prossesor so may be a different issue ?

True, but they're correlated, so it'll still give you a reasonable way to measure what's going on, especially if you record both measures a few times when you're not in Safe Mode. Plus, the temperature gun will tell you whether your phone has Covid.

This is a good plan.

The 888 has some throttling issues when playing games and does not seem to manage heat as well as the 865+. It should not have heating issues with not taxing tasks.

Hm, doesn't sound normal. How about in Safe Mode?

When using 120Hz+5G+WQHD and you open the camera it only take 60 sec to overheat.
