The microphones on an iPhone are located in three main places:

• Primary Microphone: At the bottom of the iPhone, near the charging port (Lightning or USB-C). This mic is mainly used for phone calls, voice memos, and Siri

• Front Microphone: Located at the top of the phone, either in the notch (iPhone X and later) or near the earpiece speaker. This mic is used for FaceTime video calls, front camera video recording, speakerphone, and Siri

• Rear Microphone: Near the rear camera on the back of the phone. It captures audio during video recording and assists with noise cancellation

Some newer iPhone models, like the iPhone 15 Pro, may have two microphones at the bottom, but typically only one is the primary mic for voice recording

. In summary, the iPhone's microphones are positioned at the bottom edge near the charging port, at the top front near the earpiece or notch, and on the back near the camera(s) to handle different audio tasks efficiently.
