iphone 15 overheating especially with silicone case/charging

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, 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.

I have the pink iPhone 15 and usually use the pink silicone MagSafe case. when charging it and using heavily it has been running very hot. I have had to take the case off because it felt like it was literally burning. it's been better the last couple days but don't know if it is bc I switched to a thinner plastic amazon case or because I haven't charged it yet.

what should I do? get a bumper or a different case? not use when charging? I usually keep bluetooth on for my AirPods--should I turn it off?
