Tips to improve iPhone call quality and address common issues

Addressing Call Quality Issues

iPhone users experiencing poor call quality, including muffled sound, intermittent cut-outs, or excessive background noise, can implement several strategies to improve their experience. These issues are often attributed to weak signal strength, outdated carrier settings, or physical obstructions.

In-Call Adjustments

During an active call, users should first verify volume levels and speaker settings. If signal bars are low, moving to an area with better reception, such as near a window, can help. iPhones running iOS 16.4 or later (on iPhone XR/XS and newer models) offer a 'Voice Isolation' feature. This uses machine learning to reduce environmental noise, making the user's voice clearer to the recipient. It can be activated via the Control Center during a call under the Mic Mode options.

Optimizing Device Settings for Calls

To improve cellular connection, users can toggle Airplane Mode on and off for 10 seconds. This action forces the device to re-establish a connection with the cellular network, potentially securing a stronger signal. Additionally, enabling Wi-Fi Calling can route calls over a Wi-Fi network, which is beneficial in areas with poor cellular reception.

Impact on Call Participants

It is important to note that features like Voice Isolation primarily enhance the audio quality for the person receiving the call. If the user is having difficulty hearing the other party, and that party also uses an iPhone, they should be encouraged to apply these same optimization techniques on their device.
