China Mobile said,Under normal circumstances, when the mobile phone is connected to Wi-Fi, the mobile data cannot be opened, and there is no impact on the consumption of traffic. However, if the mobile phone is connected to Wi-Fi without shutting down the mobile network, and the Wi-Fi network is unstable or disconnected, then the mobile phone will switch to the mobile data network, resulting in traffic consumption.
In addition, for Wi-Fi radiation problems of the human body, China Mobile said that in fact, there are radiation everywhere, the qualified mobile phones produced by regular manufacturers, the radiation generated during work is within the acceptable range of the human body, and the radiation of WiFi is lower. The impact on people is completely negligible.
Then there is the maintenance problem for the screen. China Mobile said that some people would use alcohol to wipe the screen, but in fact it is not desirable. Alcohol is a common organic solvent that dissolves some of the materials in your phone's screen, causing damage to the screen.
