In the design and manufacture of modern mobile phones, long-term use and heat management have been fully considered, which will not cause substantial harm to mobile phones. Playing music and watching videos for a long time will consume a lot of battery power and shorten the use time of mobile phones.
Prolonged exposure to the noise of music or other audio will have a negative impact on hearing. Pay attention to control the volume and time when listening to music or audio on your mobile phone to protect your hearing health.
