Problem:

After the phone is connected to a noise reduction headset and the noise reduction switch is turned on, the phone battery drains more quickly.

Cause:

After the noise reduction feature is enabled, the microphone filters out noise from the surrounding environment to reduce interference and allow you to enjoy a better audio experience while using the headset. If the headset is powered by your phone, the power consumption will be greater than usual.

Solution:

Disable the noise reduction feature or remove the headset when you do not need to use it in order to reduce your phone's power consumption.
