Switching between Bluetooth devices

Cobra123,

While auto-disconnecting isn't a feature you can turn on or off right now, we do think that leaving feedback would be great as it gives you an opportunity to tell the developers of features you'd like to see in the future: Product Feedback - Apple. As far as disconnecting a specific device, you're exactly right that control center will disable Bluetooth at large rather than specific devices. However, in the Settings > Bluetooth app you'll be able to do this without issue.

Hopefully this info helps a bit.

Hey there, Cobra123!

Thanks so much for using Apple Support Communities.

It's definitely super important that you're able to use the right Bluetooth device at the right time. If you're noticing that the iPhone is auto switching between active devices, we think it might be best to disconnect from the ones you're not actively using. This won't involve fully un-pairing them from your iPhone, but rather just closing the active connection which allows them to switch back and forth. Here is how to do that: Set up and use Bluetooth accessories on iPhone

We hope that this information is helpful.

​Have a great day!
