Bluetooth disconnects automatically after iOS 26 update on iPhone 12 mini.

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.

Remember, the right question often leads to the solution!

Was/Is your device Jailbroken? If that's the situation, please be informed that attributing the issues to iOS updates may not be accurate.

iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.

Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

Bluetooth interference can potentially cause connectivity issues due to the disruption of the wireless communication between devices. Bluetooth operates in the 2.4 GHz frequency range, which is also used by various other devices such as Wi-Fi routers, microwaves, cordless phones, and even some baby monitors. When multiple devices are operating nearby and using the same frequency band, interference can occur.

To mitigate Bluetooth interference issues and reduce stuttering:

1. Minimize the number of active Bluetooth devices near each other. Switch off or move away devices that are not in use or causing interference.
2. Increase the distance between your Bluetooth devices (e.g., your iPhone and Bluetooth speaker/headphones) to reduce the impact of interference.
3. Keep your devices' firmware up to date, including your iPhone and any Bluetooth accessories. Manufacturers often release firmware updates that can improve the performance and stability of Bluetooth connections.
4. Objects like walls, furniture, or large metal surfaces can obstruct Bluetooth signals and contribute to interference. Ensure a clear line of sight between your devices to optimize signal strength.
5. Some Bluetooth devices allow you to manually switch to different channels within the 2.4 GHz range. Check the user manual or settings of your Bluetooth accessory to see if you can change channels to find a less congested one.
6. If your Wi-Fi router supports it, consider using the 5 GHz frequency band for Wi-Fi connections instead of 2.4 GHz. This can reduce potential interference between Bluetooth and Wi-Fi signals.

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