Bluetooth stuttering with IOS 18.6

Apple really needs to get it together.

Bluetooth interference can potentially disrupt wireless communication between devices, causing connectivity issues. Bluetooth operates in the 2.4 GHz frequency range, which is also utilised by various devices such as Wi-Fi routers, microwaves, cordless phones, and baby monitors. When multiple devices operate simultaneously in the same frequency band, interference occurs.

It is important to note that every device in the environment will experience some degree of stuttering or performance degradation due to this interference. This limitation is not specific to Apple devices but rather a consequence of the shared frequency spectrum. Consequently, Apple may not have the ability to directly address interference issues in specific locations, as they are largely dependent on the surrounding devices and wireless traffic rather than the iPhone or Mac itself.

To effectively mitigate Bluetooth interference and reduce stuttering, the following measures can be implemented:

1. Reduce the number of active Bluetooth devices: Minimise the proximity of active Bluetooth devices to minimise interference. Disable or relocate devices that are not in use or causing disruption.
2. Increase the distance between Bluetooth devices: Maintain a sufficient distance between your Bluetooth devices, such as your iPhone and Bluetooth speaker/headphones, to reduce the impact of interference.
3. Keep device firmware up to date: Ensure that your iPhone and any Bluetooth accessories are running the latest firmware updates. Manufacturers frequently release firmware updates that enhance the performance and stability of Bluetooth connections.
4. Optimise signal strength: Obstructions like walls, furniture, or large metal surfaces can impede Bluetooth signals and contribute to interference. Maintain a clear line of sight between your devices to maximise signal strength.
5. Manually switch to different channels: Some Bluetooth devices allow users to manually select different channels within the 2.4 GHz range. Refer to the user manual or settings of your Bluetooth accessory to identify and select a less congested channel.
6. If your Wi-Fi router supports it, consider using the 5 GHz frequency band for Wi-Fi connections instead of the 2.4 GHz band. This can reduce potential interference between Bluetooth and Wi-Fi signals.

By implementing these steps, you can help minimise Bluetooth interference and improve the overall performance of Audio.

If it happens in specific places, and the same places every time, it is almost certainly microwave interference→Resolve Wi-Fi and Bluetooth issues caused by wireless interference - Apple Support. The frequency range used by Bluetooth is in an unlicensed band, and is also included in S band (2 to 4 GHz) radar. Uses include airport surveillance radar, air traffic control radar, surface ship radar, weather radar and ground penetrating radar. So if you are near an airport, body of water when larger boats and ships are present or you are near weather stations that is a likely cause. Bluetooth’s 2.4 GHz is right in the middle of S band.

To troubleshoot to see if it is a problem with your iPhone start with Reset Network Settings:

• Open Settings
  • Tap General
  • Tap Transfer or Reset Phone
  • Tap  Reset
  • Tap Reset Network Settings

• • This will erase all Wi-Fi passwords, but will not result in any other data loss.

Something else to check:

Do you have a 3rd party VPN installed, even if you are not using it? If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN, then restart your device. Don't just turn it off; delete the profile. If that fixes it, you can try reinstalling VPN, but probably shouldn't.
