Wondering if updating to iOS 17.3 may help: About iOS 17 Updates - Apple Support

(Seems there are bug fixes, improvements. and more.)

NB: It is always wise to back up your device before updating.

To check for updates go to: Settings > General > Software updates

Else: If you already have iOS 17.3 installed and still experience issues:

See if restarting your iPhone helps (deletes temporary files, re-establishes connections, often restores order):

Re: "overheating during charging"

Your device may get warm

You may notice that your device feels warmer when you:

• Set up your device the first time
• Restore from a backup
• Wirelessly charge your device
• Use graphics-intensive or processor-intensive apps, games or features, including augmented-reality apps
• Stream high-quality video

These conditions are normal and your device will return to a regular temperature when the process has been completed or when you have finished your activity.

NB: If your device doesn't display a temperature warning, you can keep using your device.

If needed, also scroll to: "If your device gets too warm" in the article below:

All the best :-)
