Because when the mobile phone is charging, the mobile phone will heat up, causing the battery to expand, making the internal parts of the mobile phone appear small displacement, these small displacement will bring great interference to the microphone when the voice is issued, resulting in the voice signal is affected, resulting in the voice easy to break.
If you want to avoid voice interruption, you can try to make a voice call without charging, or use another device to make a call. At the same time, it can also minimize the use of the phone when charging, so as not to cause damage to the internal components of the phone.
This may be due to the increased temperature of the phone's battery while charging, which causes the phone's performance to decrease and the network signal to weaken, which can lead to voice calls being disconnected or the quality of voice calls being reduced.
In addition, there may be power interference or electromagnetic interference when charging, which will also affect the quality of voice calls. It is recommended to try to avoid making long voice calls while charging, or to use peripherals such as headphones to make calls.
