Hello there, Baryco.
When having issues with Bluetooth connections, the following Knowledge Base article offers some great initial steps as well as more in-depth troubleshooting for attempting to resolve your issue:
iOS: Troubleshooting Bluetooth connections - Apple Support
if after following the initial recommendations, the following can also be helpful:
- Move your iOS device closer to the Bluetooth accessory.
- Position your iOS device and Bluetooth accessory in direct line of sight of each other. For example, move the Bluetooth accessory and iOS device to the same side of your body.
- Remove any case, stand, or other accessories from your iOS device and see if performance improves.
- Check for sources of potential interference and move both the iOS device and the Bluetooth accessory away from other electronic devices.
- Reset network settings by tapping Settings > General > Reset > Reset Network Settings.
This will reset all network settings including: previously connected Wi-Fi networks and passwords, recently used Bluetooth accessories, VPN, and APN settings.
If the steps above have not resolved the Bluetooth behavior you are experiencing, perform a software restore in iTunes.
If the issue persists after restoring your iOS device in iTunes, contact Apple for support and service options.
Thanks for reaching out to Apple Support Communities.
Kind Regards,
Pedro.
