S23 Temperature Throttling after Factory Reset

[zenfaust]

Hey,

I've been having pretty bad heat issues with my base s23 ever since the one ui 7 update, and I'm not sure what to do... hoping all have some advice, or maybe can confirm similar issues?

I'm being constantly temp throttled doing basic tasks, even just typing here has my phone at 50°C... this never used to happen. I cleared the cache, tried light performance profile, turned down refresh rate and screen brightness, stopped using 5g, turned off ram+, etc etc. None of this worked.

I eventually did a factory reset with no setting transfered, to make sure I didn't carry over problems. Then I reapplied light profile, dark mode, and all the stuff above. I did not install anything new and gave the phone a week to settle in.

Still no dice. Phone cooks if I do even the lightest of work on it, and also boils itself every time I restart it... current temp record for that is 97°C. It's worth mentioning that my battery life is fine, it's only a heat issue. As far as I can tell, there's nothing running in the background that's causing this (at least that I know how to check for) and I live in a cool climate... so its not an already hot enviroment. I'm at my wits end with this. 

Also notable: after every adjustment, like turning on light performance profile for example, the temps stayed EXACTLY the same across all tasks. You would think that it would help at least a tiny bit? But nothing I try moves the temps even the tiniest amount. Could the problem be some new feature running in the background? Maybe the ai or something?

Is there anything else I can try? My phone was cool as a cucumber for two years straight before this most recent ui update, so I know it *can* run cool. I just can't get it there anymore. Any advice would be greatly appreciated...

Hi. Im having the same issue since the update. It's frustrating. I have done all except the factory reset. I will do the factory reset today and if this does not fix it, it's bye bye Samsung for me. I love my phone and I've had it for 2 years without issue too.

Good luck... if the factory reset works for you, would you report how you managed to do it?
What's s maddening about this, is that some people claim their phone is okay... so there must be some variable causing this, or else every one would be hot now...

Clearing the cache partition is a first step.  I understand that YouTube is a prime offender of overheating, even if you don't use the app.  Go to the YouTube app settings and under "battery", make sure it is either optimized or restricted.  You can also put the app to sleep.  Putting the app to sleep and/or restricting the battery usage will still keep the app usable, it just won't wake up and go running in the background trolling for new content.  Content will update when you open the app. Since the app cannot be deleted, if you don't use it you should be able to disable it.  If you can't disable it, the next best thing is deep sleep.  You will still be able to view YouTube videos on the web through social media apps or a web browser.

You can also download Good Guardians and the Thermal Guardian module from the Galaxy store.  Using the thermal guardian will give you an idea of which apps are causing your overheating situation (if it's something other than YouTube).

Yeah, I tried the cache clear twice now: once as my initial attempt to troubleshoot, and a second time after I did my factory reset. Neither had any effect.

And unfortunately, disabling YouTube doesn't seem to be helping. I've got the guardians app, and it's not very helpful, because the phone gets hot during everything, and it says every app is the cause. Was I charging? Then charging was the cause. Did I use Firefox? Then Firefox was the cause. The only time it's happy is when it's completely idle and the screen is off. I can't disable 100% of everything... that's like saying the phone will work so long as you don't use the phone.

I'm so frustrated with this, it's unreal.

One of my older devices just after 1UI7 installed did heat up for about a week, then one of the batteries started to show signs of heat damage, that's expensive to replace.
When I brought it to my neighbor who's an Assurion tech he said the battery didn't fail bc of the heat per se, but that the battery failing is what caused the heat.., i dunno, it's left me feeling that Samsung can intentionally (randomly) run secret code to fail a phone to get more sales.. lol

[zenfaust]

I hope that's not the case... my phone actually has a brand new battery in it... my original started bulging in January, so I had it replaced, and the replacement battery has been fine from then on until now. Even now it lasts as long as it ever did. I'm almost 100% this is something else, but I'll be damned if I can figure it out.

According to the internals, it's my cpu that cooks, and eventually that starts warming up the rest of the phone.

One thing to note is that you have an older phone and the newer operating system makes more demands on the hardware, which can cause overheating.  No, you can't turn off everything, but you can make sure your battery optimization settings are correct.  You can go into settings/battery/background usage limits and turn on "put unused apps to sleep". This will prevent apps you don't use very often from running in the background, including updating.  They will still be usable when "woken" and updates and new content will download when they are opened.

[zenfaust]

Yeah, I've pretty much disabled everything except the bare necessities at this point to no success... do you really think the snapdragon 8 gen2 isn't powerful enough to run oneui7? Despite spiking in heat for everything, guardians app says the cpu usage isn't even touching 50%

Maybe *carefully* try codes here to diagnose..
