Why is there a faint noise near the earpiece when the Xiaomi 15 is in standby mode?
The faint noise near the earpiece when the Xiaomi 15 is in standby mode is a result of the phone's routine background processes. While in standby status, the phone continuously searches for a stable network connection, either through mobile data or Wi-Fi. This intermittent search for the network, including signal adjustments and connection handoffs, can sometimes produce a soft noise that is heard near the earpiece. This is completely normal behavior and does not indicate any malfunction or issue with the device. Please rest assured that this noise does not affect the phone's performance, and you can continue using the device as usual.
