Listening to music and reading novels on the phone would generate a certain amount of computing and storage workload, causing the phone to heat up. In addition, the phone would constantly generate heat from friction with the air during use. This heat could cause the phone to heat up. If the phone continues to heat up, it may affect the performance and user experience of the phone. It is recommended to reduce the time spent listening to music and reading novels or turn off the phone when it is hot and use auxiliary equipment such as hand warmers to reduce the temperature of the phone.
