iPhone 15 Pro Max overheating and battery health at 79

My iphone 15 pro max has been really bad with heat management ever since I got it, I now sit at 79% with only 666 cycles. If I use it heavily it genuinely gets uncomfortable to hold. Is it just my phone?

iPhone 15 Pro Max, iOS 26

Apple recommends replacing the battery in an iPhone when its health dips to 80%. Your heat issues are being caused by a battery which is starting to fail and you need to schedule an appointment at your Apple Store to have them replace the battery --> iPhone Battery Replacement - Apple Support
