In addition to weather and environmental factors, there are five main reasons why mobile phones heat up:
1. Run high-energy-consuming apps such as playing 3D games, playing videos, and transmitting large amounts of data, causing the CPU to continue to run at a high load.
2, while charging while playing games or phone battery input, output, which will not only lose double power, but also may cause harm to battery performance, it is best to avoid this behavior.
3. Using a bad lithium-ion battery or a poor-quality copycat is not a problem for iPhone users, as long as they don't buy an iPhone that can replace the battery and has dual SIM and dual standby.
4. Mobile App fault Sometimes some apps run abnormally, which will occupy a large amount of memory and cause the CPU to run with high load.
5. Protective Cases and other coverings With certain protective cases may affect the heat dissipation of the iPhone and cause the phone to become hot. Mobile phone fever may not only feel too hot to hold the iPhone, and even some people because of half an hour of mobile phone talk, close to the left cheek of the phone burns, rub medicine for three or four days, but also cause damage to the battery, and induce other risk factors, causing additional harm.
