iPhone 17 Pro Charging Hiss Reported by Users

Owners of the iPhone 17 Pro and iPhone 17 Pro Max have reported a subtle hissing or static noise emanating from the devices' bottom speakers while charging, according to numerous accounts shared on online forums since the phones' launch in September. The issue, described by users as resembling interference from an old radio or low-level electrical buzz, appears limited to Apple's latest Pro models and does not affect the standard iPhone 17.

The noise typically emerges when the device is connected to a power source, whether via Apple's official wired chargers, third-party cables, or MagSafe wireless pads. Affected individuals note that the sound ceases immediately upon unplugging the phone. In many cases, the hiss becomes audible when playing audio or video with the volume turned down to mute, or even when no media is active and the screen is awake. Some users have also detected faint crackling during actions like scrolling through webpages. While the disturbance is not constant for everyone, it tends to stand out in quiet settings, such as a bedroom at night.

Discussions about the problem have proliferated on platforms including Reddit, Apple's Support Community, and MacRumors...
