You could have only had your iPhone for a few days at best at this point. Your phone is still indexing the data you moved over to the device, which can take a few days to complete. So even not using the phone much doesn't mean the phone isn't doing anything. And during this process the battery is being used, which does generate heat naturally in a process called Thermo Dynamic Exchange. Give the phone a few days to complete it's housekeeping activities.


And let's also define overheating. When an iPhone overheats, it displays a red thermometer on the screen and advises you can't use the phone until it cools down. If you're not seeing that, your phone ISN'T overheating.


I would recommend you Force Restart your phone, which will force close any app running in the background by following this procedure exactly. In the last step, while holding the side power button, KEEP HOLDING even when you see the slide to power off slider and KEEP HOLDING it until the screen goes black and KEEP HOLDING it until the Apple Logo appears, THEN let go --> Force restart iPhone - Apple Support
