Is it harmful to send text messages when the mobile phone is first charged?

During the trip, or afraid of delaying the call, many friends will use the travel charger to turn on the phone when the phone is dead. Charging in the boot state, as long as you don't operate the phone, there will be no adverse effects. However, if you answer the phone, send text messages, download CRBT, MMS and play games online, it will be harmful to your mobile phone, people and batteries. There are three reasons:

First of all, the voltage of the mobile phone is higher when it is charged than when it is in standby. If you answer the phone and make a call at the same time, the voltage at the moment of talking or connecting to the network will be many times higher than usual, which is easy to damage the sensitive parts inside the mobile phone. Secondly, it goes without saying that while using the mobile phone while charging, the radiation amount is dozens of times that of usual. Thirdly, because the service life of the battery is calculated according to the charging and discharging cycle, the charging times directly affect the battery life. If the power supply is unplugged many times during charging, the service life of the battery will be shortened due to repeated charging and discharging. Therefore, when using the travel charger with the phone turned on, don't answer the phone. If you have to answer an important phone call, it is recommended to use another phone to call back. If you have to, unplug the charging power and then answer the phone.
