Practical Scenario: A User Want To Know Is S21 Ultra Overheating Issue Is Normal For Everyone

S21 Ultra overheating issues?

I have the US S21 Ultra, and it’s pretty hot to the touch after opening just a few apps and browsing. After only 90 mins of screen time, I’m already down to 67%. I looked at the battery log and the majority of the drain is from phone calls. But even when I’m not on calls, it’s regularly at 41 degrees Celsius or more. Is this normal for everyone?

Also, I have VZW prepaid and moved my Sim from a 4g note 10+ to this phone. I don’t seem to get 5g, nor is there a selection on the settings to choose 5g. Do I need a different Sim?
