Locating iPhone Microphones

Before cleaning an iPhone microphone, knowing where it is located is necessary, as the device comes with multiple ones for different purposes. In total, your iPhone has 3 microphones consisting of the bottom, front, and rear mics

The bottom microphone is on either side of the charging port and is mainly used for phone calls

In contrast, the front mic is located on the top of your iPhone, next to the earpiece. This microphone is responsible for recording front-camera videos, connecting to Siri, and speaking on the speakerphone.

Lastly, the rear mic is located at the back of your device and fulfills the purposes of recording videos from the rear camera, phone call noise cancellation, Siri, and FaceTime.
