Why does the REDMI A5 have noise when listening to FM Radio while charging?

Thank you for supporting REDMI products.
If the phone has noise when listening to FM Radio while charging, please refer to the following details:
1. Due to inherent design of the REDMI A5, it is common to experience unwanted noise or interference when listening to FM Radio while the device is charging;
2. This will happen because the charging process generates electromagnetic interference, which can disrupt the radio signal;
3. Additionally, the phone’s charging cable and internal circuits will act as unintended antennas, further amplifying the interference and degrading the overall audio quality of the FM broadcast.
It is recommended that you not charge the phone while using FM Radio to avoid interference.
