Let’s define “overheating”. If an iPhone overheats it shuts down so it can’t be used, and displays a message saying it must cool down before it can be turned on, and it will probably be unusable for an hour or so. If you are seeing this it is a hardware problem and you should contact Apple support:
- Click on “Support” at the top of this page
- Go to Contact Official Apple Support
Note that both of the above have options to receive a callback or chat
If you are not seeing this your phone has not overheated. However, if you fast charge your phone may get very warm, and may pause charging at 80% and display a message saying that charging has paused, and will resume when the phone cools down. This is NOT overheating, and is normal when fast charging. It also won’t prevent you from using any app you have on your phone.
Also, some apps that use a lot of energy or that use cellular data rather than Wi-Fi can cause the phone to run warmer.
==========================================
Regarding Bluetooth, as you clearly have a new phone it must be individually paired with each device that you want to communicate with. Pairings do not transfer from one device to another. See→Pair a third-party Bluetooth accessory with your iPhone, iPad, or iPod touch - Apple Support. And note that most BT devices can only pair with a small number of phones before they need to be reset, or have the pairing table cleared.
