Phone overheating

[Ocean_Waves_S21plus]

My samsung galaxy s21+ often overheats after only 15-20 mins of gaming/scrolling on YouTube. Has anyone got any suggestions on what might be going on?

When you say over heating, do you mean gets warm to the touch. Or over heating to the extent the phone comes up with an over heating warning and will shut down?

First things first - have you ever Wiped Partition Cache on your device?

It is recommended to do so after each major OS update and every so often after security patches.

I perform this on my device every 3 months or so. It won't delete your data but does get rid of temporary cached files.

Hi @Ocean_Waves_S21plus 👋 

Excellent advice and suggestions by @Piper123  and @Fiona26  👍

I would suggest to try Safe Mode. 

• 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.
