Mystery Hiss Plagues iPhone 17 Pro Users Charging

Owners of the iPhone 17 Pro and Pro Max have reported a peculiar hissing noise when charging their devices. This sound, likened to an old radio, originates from the phone's bottom speakers and is noticeable even when the volume is turned down. Initial user attempts to resolve the issue by switching to third-party charging equipment or using MagSafe wireless charging were unsuccessful.

Further investigation revealed that the problem is not hardware-related, as confirmed by an Apple Support engineer through diagnostics. The engineer acknowledged Apple's awareness of the situation and communicated plans for a future software update to address the persistent hiss. Users have noted the sound can also occur when launching the Camera app while charging.

This charging-related hiss is the latest in a series of issues reported by iPhone 17 Pro users since its launch. Previous problems included scratching, color changes on the orange model, and Wi-Fi connectivity failures. While Apple has addressed some of these earlier concerns with guidelines and software patches, the charging hiss remains an ongoing concern for affected users.
