iPhone 17 Pro is annoying with noise in the speaker when charging

Owners of the current iPhone 17 Pro models report a noticeable audio phenomenon. In forums and social networks, many users report static noise or hissing from the speakers as soon as the device is charging.

Noise during charging

The sound is reminiscent the reports according to one Radio without reception. It mainly occurs when charging with a USB-C cable, but can also be heard when using MagSafe chargers, but is usually quieter there. The noise is not necessarily linked to media playback. Some users notice it when music or videos are muted, others even without an active audio app. Some people even report a slight crackling noise when scrolling through websites. If the power is disconnected, the noise disappears immediately. This suggests a connection with the charging process. It is still unclear whether the cause lies in the hardware or the software.

Investigation by Apple engineers

How now MacRumors Citing forum reports, Apple is aware of the problem. One affected Reddit user wrote that the case was escalated to the engineering team after contacting Apple Support. Accordingly, the developers requested, among other things, video recordings of the noise as well as photos of the charging port and the accessories used. The problem has been acknowledged, but a solution is still pending. The feedback from the user community so far can be summarized as follows:

• Both the iPhone 17 Pro and the iPhone 17 Pro Max are affected.
• Replacing devices via Apple Care often didn’t help because replacement devices were also affected.
• The noise also occurs with original Apple accessories.
• The current operating system iOS 26.2 does not yet contain a fix.

Technical background and causes

Since replacing the hardware often had no effect, users and observers suspect a more fundamental error. Both a possible problem in the shielding of certain batches of devices and a software error that leads to disruptions in audio processing during the charging process are discussed. Similar cases have occurred in the past with previous iPhone generations, but had different triggers. Apple has not yet given a timeline for a fix. It is currently unclear whether a future software update can provide a remedy or whether further measures are necessary.
