iPhone 17 Pro and Pro Max owners are experiencing issues with their devices' speakers, as they have complained about a static or hissing sound that appears when the iPhone is charging.

There are many discussions about the issue on Reddit, the forums , and the Apple Support Community, where affected users report a noticeable static sound “like an old radio.” Some report hearing it when playing audio and turning the volume down, while others say the static is heard without anything playing through the speakers. In some cases, there is a low-pitched click or hiss when browsing websites while the iPhone is charging, and some hear the sound at low volumes even when the iPhone is not charging.

Affected users report that the sound can be heard with all types of chargers, including official Apple chargers. Charging with MagSafe also causes the issue, but users report that the static sound is quieter. Unplugging the iPhone from the charger eliminates the sound for users experiencing static noise while charging.
Some iPhone 17 Pro users have exchanged their devices for new ones, but have encountered the same problem.

A Reddit user has contacted Apple support and says the issue has been escalated to Apple engineers. Apple appears to be working on a fix, but the iOS updates released so far don't seem to be fixing the issue. The sound is subtle according to most reports, so it could be a widespread issue that only those who are sensitive to sound have noticed.
