Experts reveal: Playing with your phone while charging isn't that scary
|
Many people have the habit of playing with their phones while charging, but the phones tend to get hotter than usual. So some people think that playing with your phone while charging will not only damage it, but also make the phone's radiation stronger. Is this true? According to People's Daily Online, Zhou Hongzhi, an associate professor at the School of Applied Mathematics and Physics of Beijing University of Technology, revealed this. He said that playing with a mobile phone while charging is actually the result of heat accumulation . The charger provides a voltage of about 5 volts when charging the battery, but the mobile phone only needs a voltage of about 3.7 volts to 4 volts when in use. When playing while charging, there is a step-down system in the mobile phone that will play a role in reducing the voltage, but this step-down system will consume power and release the consumed power in the form of heat. This heat is superimposed on the heat generated by the mobile phone during use, and the mobile phone will be hotter than usual. At present, most regular mobile phones have a set of temperature control devices inside. If the mobile phone reaches or exceeds a certain temperature, the charging process will be terminated or the mobile phone will be forced to shut down . In response to some people's concerns that playing while charging will increase the workload of the mobile phone, Zhou Hongzhi said that the workload of the mobile phone is mainly related to its running program. Charging will not increase the workload of the mobile phone, let alone damage the mobile phone . Moreover, the life of the mobile phone battery is usually the same as the use cycle of the mobile phone. As long as you use a regular mobile phone and charger, you don't have to worry about the battery being damaged prematurely. In addition, Zhou Hongzhi said that the amount of mobile phone radiation has nothing to do with whether the phone is charging or not. Therefore, playing with the phone while charging will not increase the phone's radiation. Mobile phone radiation is mainly related to the process of sending and receiving its signals. Nowadays, mobile phones have an automatic power control (APC) system, which can ensure the stability of mobile phone signals. In simple terms, the distance between the mobile phone and the base station will change during the movement, and then the sending and receiving of its signals will also change: if the signal is very strong, the mobile phone will automatically adjust the emitted radiation power to the minimum; when the signal weakens, the mobile phone will automatically increase the emitted radiation power. However, as long as the mobile phone has passed the national 3C certification, the maximum value of its radiation power will not exceed the limit set by the state.As a winner of Toutiao's Qingyun Plan and Baijiahao's Bai+ Plan, the 2019 Baidu Digital Author of the Year, the Baijiahao's Most Popular Author in the Technology Field, the 2019 Sogou Technology and Culture Author, and the 2021 Baijiahao Quarterly Influential Creator, he has won many awards, including the 2013 Sohu Best Industry Media Person, the 2015 China New Media Entrepreneurship Competition Beijing Third Place, the 2015 Guangmang Experience Award, the 2015 China New Media Entrepreneurship Competition Finals Third Place, and the 2018 Baidu Dynamic Annual Powerful Celebrity. |
