I believe that many friends will encounter this situation. When they are chatting or watching TV series, they suddenly find that their mobile phone is going to run out of power. Please connect the power and continue watching. So the question is, if the mobile phone is used while charging, then the power consumed by the mobile phone comes from the battery or the charger?
Let's first learn about the power consumption when charging the mobile phone. When the mobile phone is charging, the current from the charger will be divided into two parts, the vast majority of which will supply the battery to help the battery complete the storage; the other part will supply the main board of the mobile phone to meet the needs of the mobile phone to complete other work. If it is used while charging, the current supplied to the main board of the mobile phone will increase, and correspondingly, the current supplied to the battery will decrease.
Because the battery can only work in one-way state, either charging or discharging, it is impossible to output the power at the same time as the input power, so it depends on the power of the charger.
If the charger's power is very high, it can bring huge current. Even if the mobile phone is used while charging, the battery will always be storing power, that is, the power has been increasing. However, if the charger's power is very low, or the quality of the data line is poor, and the power consumption of the mobile phone is very large, then the power from the charger will be in short supply. What should I do? At this time, I need to use the battery power.
Therefore, when the power of the charger is high enough, the mobile phone can be charged when it is in use, but the charging time may be longer; when the power of the charger is not high, the charger not only cannot charge the mobile phone, but also needs battery power, and the phone will charge less and less.
The latter is very common in the past, but with the rapid charging becoming more and more popular, the power of the charger is very high, so the current mobile phone can basically meet the needs of charging while using.
However, when the charger charges the battery, heat will be generated due to loss in the process of converting electrical energy into chemical energy storage; at the same time, heat will also be generated when the mobile phone is running under high load, so the mobile phone will be hot.
So the conclusion is that when you use a mobile phone while charging, the power consumed comes from the charger. Unless your charger has low power or poor data line quality, you need the battery to provide power.
In addition, although the mobile phone can be charged while using, the heat generated in this process will also damage the battery and reduce the battery life; at the same time, there are uncertain risk factors such as explosion.
Therefore, it is recommended that you use the mobile phone reasonably. Not only the mobile phone needs to supplement energy, but also people need to rest. Playing the mobile phone all the time will also cause cervical spondylosis, myopia and other health problems. It's also a good choice to put down your mobile phone occasionally to exercise and chat with your family and friends face to face.
