This disconnection issue with Beats Flex and Studio 3s specifically when Apple Fitness is active on iOS 26 is a known Bluetooth audio routing conflict. When the Fitness app starts an active workout session, iOS 26 aggressively manages audio routing and can inadvertently trigger a Bluetooth reconnect cycle on W1-chip Beats devices.
Here are the steps to resolve it:
1. Forget and re-pair both Beats devices:
- Go to Settings > Bluetooth, tap the (i) next to each Beats device and select "Forget This Device"
- Re-pair them fresh by holding the power button until the LED flashes
2. Disable Automatic Ear Detection (if applicable):
- Settings > Bluetooth > tap (i) next to the Beats device > turn off "Automatic Ear Detection"
- This prevents the device from disconnecting when it detects it has been removed
3. Check for Beats firmware updates:
- Connect the Beats to your iPhone and open the Beats app (if installed), or check Settings > Bluetooth > device info for firmware version
- Outdated firmware can cause compatibility issues with newer iOS versions
4. Reset network settings on the iPhone:
- Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings
- Note: This will also reset Wi-Fi passwords, so have those handy
5. Workaround while Apple investigates: Before starting your Apple Fitness workout, manually disconnect and reconnect the Beats from Settings > Bluetooth. This refreshes the Bluetooth session and can prevent the mid-workout dropout.
If the issue continues after iOS updates, please report it at feedbackassistant.apple.com with your device model and iOS version.
