my phone has been hot for no reason for like 15 min

Let's define overheating. When an iPhone actually overheats, it displays a red thermometer and a message the phone can't be used until it cools down. If you're not seeing this, your phone may be warm, but isn't overheating. What are you doing on your phone when it was hot? Streaming videos, using social media, particularly Meta apps, like Instagram/WhatsApp/Messenger or Facebook, taking photos, streaming music, etc., are notorious users of power and when something uses power, the battery has to work harder. When a battery works harder, it generates heat naturally.

What is your current Battery Health? Open Settings > Battery > Battery Health - if it is near, at or below 80%, the useful life of the battery has been used and when batteries are on their way to failing, they get hot just to work.
