When the mobile phone is charging while playing, does the power consumed come from the battery or the charger?

Let’s first take a look at the battery usage when charging. When the phone is charging, the current from the charger will be divided into two parts. Most of the battery will be supplied to help the battery to be stored. The other part will be supplied to the phone’s motherboard. Meet the needs of the phone to do other work. If it is used while charging, the current supplied to the main board of the mobile phone will increase, and accordingly, the current supplied to the battery will be reduced.


Since the battery can only be in the one-way working state, either charging or discharging, it is impossible to output power while inputting the power. At this time, it depends on the power of the charger.

If the power of the charger is very high, it can bring a huge current, so if the mobile phone is used while charging, the battery will always be stored, that is, the power is always increasing; but if the power of the charger is very low, or The quality of the data cable is not good, and the power consumption of the mobile phone is very large, so the power from the charger will be in short supply. How to do it? At this time, it is necessary to use the battery storage power.


Therefore, when the power of the charger is high enough, the mobile phone can still be charged when it is used, but the charging time will be longer; when the power of the charger is not high, the charger can not only charge the mobile phone but also need to be powered by the battery. The mobile phone will be charged less and less.

This latter situation is very common in the past, but with the popularity of fast charging, the power of the charger is very high, so the current mobile phone can basically meet the charging while using.


However, because the charger charges the battery, in the process of converting electrical energy into chemical energy storage, heat is generated due to loss; at the same time, the mobile phone generates heat when it is operated under high load, so the mobile phone will appear hot.

So the conclusion is that the phone is used while charging, and the power consumed comes from the charger. Unless your charger has low power or poor data quality, you will need the battery to supply power.


In addition, although the mobile phone can be fully charged while using it, the heat generated in this process will damage the battery and reduce the battery life; there are also uncertain risk factors such as an explosion.

Therefore, it is recommended that everyone use the mobile phone reasonably. Not only does the mobile phone need to replenish energy, but the person himself needs to rest. The mobile phone will also produce health problems such as cervical spondylosis and myopia.
