7 Delete Old Bluetooth Profiles
You probably connect your iPhone to quite a few Bluetooth devices in your day-to-day life. And while old unused Bluetooth profiles probably don’t slow down your device significantly, they can pretty quickly clutter up your Bluetooth settings — especially ones that you’ve only used once.
To clean it up, just navigate to Settings > Bluetooth. Tap the “i” icon next to a device and then tap Forget This Device. iOS will then prompt you with another Forget Device button. Tap on that and the Bluetooth device profile will be deleted from your list of previously paired devices. Luckily, it’s also pretty easy to reconnect to devices you actually need to pair to again.
