Why is there a buzzing sound in the REDMI Note 13 5G during software downloads?

During software downloads, especially when dealing with large data volumes and high power voltage, you can hear a slight buzzing sound due to the electrical current. This is a normal occurrence and does not affect the phone's normal usage or performance. However, it is advised not to download software while holding the phone close to your ear for calls to avoid any discomfort from the buzzing sound. The phone will continue to function correctly, and this sound is just a minor byproduct of the device handling large data transfers and power loads.
