Some users have experienced very hot phone in a morning, I am sure. That is usually caused by an other app that have high CPU usage. There is a way to read CPU usage. That combined can prevent phone overheating, and prevent damage to the phone. When certain app high CPU usage is detected at the start of sleep tracking, then user wuold be alerted and if plausible app that caused it name stated.
