Use this guide to replace the microphone in your iPhone 16 Plus.
If your iPhone's having a hard time picking up your voice, or has intermittent issues, the microphone might need to be replaced.
The microphone in this guide is the primary of three microphones, and can be replaced as a single unit. Another microphone is integrated with the charging port assembly, and a third is integrated with the power button assembly.
