Is it safe to use the phone while charging?

Many people have cell phone dependence, even when charging, we are also used to look at the phone or call while charging. But is it safe to use the phone while charging?

Will it hurt the phone to use the phone while charging?

In fact, the work load of the phone is mainly related to its running programs, charging is not going to increase the load of the phone. However, as we all know, the temperature of the phone itself will be higher than normal when it is charging, and when we use the phone for a long time, the phone will often get hot.

The lithium battery inside the phone has a tolerable operating temperature range, continuous high temperature can easily lead to a decrease in battery capacity, and may even cause internal short circuit or rupture of the battery shell, and in serious cases will lead to leakage, spontaneous combustion and other accidents.

Of course, cell phones generally have a temperature protection mechanism, and the degree of battery heating will be controlled within a safe range. That is to say, when the phone is charging, in principle, you can use it, but once the phone gets hot too much, you have to stop charging and using it. Of course, the PTC in the USB cable can also prevent overheating.

Does the radiation increase to use the phone while charging?

Mobile radiation is mainly related to its signal sending and receiving process, and mobiles have a set of internal automatic power control (APC) system, which make the signal to remain relatively stable. 

The radiation produced by the cell phone is non-ionizing radiation, electromagnetic wave frequency is low, the energy is weak, the impact on the human body is subtle. As long as the certified cell phone, its radiation will not exceed the radiation safety standards.

Simply words, the amount of mobile radiation has nothing to do with charging and is not a health hazard!

Does it cause electrocution to use the phone while charging?

You may have seen similar news: Using the phone while charging leads to electrocution or fire. But when we use the phone while charging ourselves, there is no accident, why? In what situation is it easy to cause an accident?

1. Using poor quality chargers

From the accidents in recent years, the victims mostly used counterfeit and shoddy chargers. Due to the cost, many inferior chargers are prone to short circuit, causing leakage. Once the charger leaks, the dangerous voltage will be transmitted to the ground end of the phone power 5V, if the body touches the phone, and other parts of the body touch the ground, it will form a circuit to the ground, thus causing an electric shock accident.

2. Charging your phone from computer

Many people have tried to use the computer to charge the phone, especially at work, in fact, this charging method is a safety hazard.

The computer's USB port is not equipped with intelligent regulation of current and voltage chips like cell phone chargers, when the computer is reading and writing hard disk, running software and other work, the internal voltage of the USB port is unstable. If the quality of the charging cable is poor, it may lead to electrocution due to high voltage output from the charging port.

3. Charging during a lightning storm

A moment of lightning occurs, the huge voltage generates may impact some electrical equipment, into the house on a variety of wires will generate high-intensity electromagnetic induction, resulting in an instantaneous increase in voltage in the wire, resulting in circuit failure.

When the charger is connected to the indoor power supply, lightning energy may be transmitted through the wire to the charger, and then transmitted to the phone, if you are playing with the phone at this time, it is possible that the current fluctuations may cause electrocution. So in the time of thunder, it is not recommended to use the charger to charge the phone.
