Hello!
We're grateful for your participation in the Apple Support Community. I can offer some suggestions to help you with your situation:
Monitor Usage:
If your iPhone 12 Pro is still running hot even after a battery replacement, it might be helpful to monitor your device's usage. Check the battery usage settings to see if there's any specific app or process that's consuming an unusually high amount of power.
Restart Your Phone:
Sometimes a simple restart can help resolve software-related issues that might be causing your phone to run hot. Hold down the power button and slide to power off. Then turn your phone back on after a moment.
Check for Software Updates:
Make sure your iPhone is running the latest version of iOS. Software updates can include bug fixes and optimizations that might help with temperature issues.
Check Background Activity:
Some apps or services might be running in the background and causing your phone to heat up. Go to "Settings" > "Privacy" > "Location Services" to see which apps are using your location, and consider disabling location services for apps that you don't need them for.
Check for Overheating Apps:
If a particular app is causing your phone to overheat, try deleting and reinstalling it. It's possible that a corrupted installation might be causing the issue.

If you've tried these steps and your iPhone is still running hot, it might be best to contact Apple Support Tel.: 0800 6645 451 (DE) directly. They can provide more personalized assistance based on your device's specific situation.
