There are several reports in the community of other members experiencing the same issue. It’s a possible bug, but better to error on the side of caution and get your device properly diagnosed.
Please have Apple perform diagnostics on your iPhone. It can be done in person at an Apple Retail Store or at an Apple Authorized Service Provider. You can also contact Apple Support and request remote diagnostics.
If you’re in the US, please call 1-800-MY-APPLE, or outside the US, consult the support articles below. In Canada, call 1-800-263-3394.

See the post from Jeff Donald and schedule an appointment at the Genius Bar to have your phone tested.

Same with me. It’s frustrating using my iPhone 15 pro max now. And to think that the phone is so cold, yet false temperature warning just keeps popping up.
