S24 ultra getting really hot

[Krystian101]

I've been ignoring this problem for a while but my phone would get really hot whilst just being in my pocket with nothing on.

I've used a good third party app to see that my phones battery temp goes up to 41*C whilst doing nothing.

This is starting to worry me now and I'm wondering for any help/advice ?

Restart the phone. Could be a runaway app.

I've been restarting the phone every so often the last time was 17 hours ago

What's is running typically? Check the apps you have installed around about the time issue started

I've just uninstalled apps I don't use or are suspects of it, although i can't remember if an app caused it as this problem was roughly after 2 weeks of getting the phone, so some time ago

Hi,
While it’s normal for your phone to heat up occasionally, the optimal temperature can range from 0°C to 35°C. Temperatures between 36°C to 43°C are still considered normal, but anything above this is unsafe.

Just back up your phone and factory reset it. Leave it as stock for 24 hrs and monitor. In that time, don't load any 3rd party software or customisations. Don't load your backup. If the phones temperature remains normal, then consider reinstalling your backup, but refrain from installing any of the 3rd party stuff. If you really need 3rd party apps, then download them manually one by one and check what effects each one has on the phone temperature.

@Krystian101 perhaps try these troubleshooting steps. 

• Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 
• Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. Alternatively long press the power off button and then long hold on Turn Off to get to Safe Mode. 
• Run the diagnostic tool in your Samsung Members App. 

If your not seeing a pop up warning on the phone and or the phone isn't shutting down then the phone isn't seeing itself presenting a problem. 

If i can be of any further help please don't hesitate to ask  😎
