According to lithium grid analysis, the voltage when charging the phone is higher than standby, if at the same time to make calls and other operations, in the moment of calling or connecting to the network voltage will exceed the usual many times, easy to make the phone internal sensitive and complex parts are damaged, which leads to frequent maintenance of cell phones. Secondly, the radiation during charging is also tens of times higher than usual, which can cause damage to the human body. In addition, because the battery life is calculated according to the charge and discharge cycle, so the number of charges directly affects the phone battery life. If you repeatedly unplug the power will make the battery due to repeatedly put the charge and reduce the life. Therefore, when the phone is charging in the power-on state, Lithium Grid recommends that you do not use the phone while charging it.
Lithium battery can be charged while the hazards
The charging voltage added to both ends of the battery when charging is higher than the terminal voltage of the battery, the battery does not discharge. At this time, the battery is running in the circuit as a load, while the power supply of the phone components is provided by the charger. Therefore, using the phone while charging, in theory, while charging will have an impact on the lithium battery.
What are the hazards of lithium batteries can be charged at the same time
First, overcharge: the lithium battery charging time is too long, charging the power to exceed the rated capacity of the battery. Now the phone will generally have a protection mechanism, after the battery is fully charged, the phone's internal circuit automatically disconnects the charging circuit. But do not exclude some poor quality seat charger or universal charger is not designed to protect the circuit. So when using the seat charger or universal charger, less damage to the lithium battery, please pay attention.
Second, over discharge: usually the phone will automatically shut down when the power is too low (due to low battery voltage). But if you reboot will find that the phone still has power to use (battery voltage back up). Automatic shutdown is a manufacturer's protection mechanism for the phone's battery. Battery over discharge will cause serious damage to the battery life, so when the power is too low, please charge it. It is recommended to charge the battery when it is convenient to ensure that the battery has sufficient power, and some lithium battery users have such a habit.
Third, overtemperature: high battery temperature will also affect the life of the battery. Frequent discharge of the battery will heat up, in the actual use of the battery over temperature, usually due to this reason. Therefore, playing large games or running other power-consuming programs need to pay attention to heat dissipation, as well as control the program running time, reduce the lithium battery harm method.
Fourth, under-temperature: lithium batteries are not allowed to charge when the battery temperature is below 0 degrees Celsius, which has an impact on lithium batteries.
Fifth, overcurrent: the use of excessive power charger to charge the battery, will cause damage to the battery. However, manufacturers are now alarmed when the charging current is too high. Of course, the seat charger and universal charger whether there is an alarm function will not know. The most serious case of overcurrent is a short circuit. Short circuit may cause the battery to explode and burn, please do not try. Basically, in daily life, the common impact on the battery life is so much. Good use habits to extend the use of the battery time and life is very helpful, regulate the use of lithium batteries to avoid risks.
