A growing number of iPhone 17 Pro owners have begun noticing something strange while plugging in their devices. When the phone is charging, some users report a faint but persistent hissing or static sound coming from the speakers. The issue appears subtle at first, but once you notice it, it becomes difficult to ignore. So far, the exact cause remains unclear.
Reports of this unusual speaker noise have surfaced across multiple online platforms. Discussions on sites like Reddit, Apple’s official support forums, and coverage from outlets such as MacRumors suggest the issue is affecting both the iPhone 17 Pro and iPhone 17 Pro Max. In many cases, users say the sound only appears when the device is connected to a charger, whether through a wired cable or MagSafe, and the display is active. As soon as the phone is unplugged, the noise stops.
A quiet hiss that becomes hard to forget
For some owners, the sound becomes noticeable when audio is playing and the volume is turned down very low. Others claim they can hear a radio like static even when the phone is idle and sitting on a desk. A small number of users have even mentioned hearing the noise when the device is not charging at all, although those cases appear to be less common.
The issue does not seem to affect every unit. While some users hear the noise consistently, others experience it only occasionally, and many have not noticed anything unusual. This inconsistency suggests the problem may be limited to a specific batch of devices or tied to certain charging conditions.
The faint hiss may go unnoticed in busy or loud environments, but it can become much more apparent at night in a quiet room. For people who charge their phone next to the bed, the sound can feel distracting or unsettling, even if it does not interfere with normal phone functions.
Several users have tried exchanging their devices, hoping a replacement unit would fix the problem. In some cases, the noise returned on the new phone, pointing to a potential underlying issue rather than isolated hardware defects. According to reports, Apple support representatives are aware of the complaints and have reportedly escalated the matter to engineering teams for further investigation.
If the cause turns out to be software related, such as power regulation behavior or an audio driver issue, a future iOS update could quietly resolve it. Apple has addressed similar post launch concerns in the past through over the air updates. Earlier this year, the company rolled out fixes for camera related issues affecting the iPhone Air and the iPhone 17 Pro, which were later resolved through software improvements.
For now, Apple has not issued a public statement acknowledging the speaker noise reports. Until more information emerges, affected users are left waiting to see whether the issue will be addressed through an update or require hardware replacements.
