iPhone 17 Pro and iPhone 17 Pro Max users are experiencing something very unusual: a faint hissing or static-like noise coming from the phone’s speakers while charging.
According to a report by MacRumors, citing discussions on Reddit, Apple’s Community Support, and its own discussion forum, affected users are noticing a hissing sound or noise when their phone is charging (via a wired or MagSafe charging solution), and the screen is awake. Unplugging the iPhone stops the sound.
Subtle but hard to ignore once you hear it
While some users report hearing an unusual sound when playing an audio track through the iPhone 17 Pro’s speakers and lowering the volume, others claim the noise (like static from a radio) is audible when the phone is sitting idle. In fact, a couple of users have reported hearing the sound even when the iPhone isn’t charging.
While the issue isn’t widespread (at least at the moment), it is big enough to have gathered enough coverage. Some users are hearing a hissing or static sound consistently, others only randomly, while many aren’t experiencing the issue at all, suggesting it affects only a limited number of iPhone 17 Pro users.
While you might not hear the subtle hissing in a noisy environment, it may become more noticeable when you plug in your phone at night in a quiet bedroom. Even though the issue doesn’t seem to affect day-to-day operations, it raises questions about potential causes and the workarounds.
Some users have reportedly exchanged their iPhones for new ones, only to reencounter the issue. The report also mentions that Apple support is aware of the problem and has forwarded it to its engineers.
If the issue is related to a software fault, such as power regulation levels or audio driver malfunctioning, an OTA update could quietly resolve it. However, if that’s not the case, the company should provide free replacements. So far, Apple hasn’t acknowledged the issue.
At launch, the iPhone Air and the iPhone 17 Pro also had specific camera issues that Apple later fixed.
