How can I turn off Bluetooth from the Control Centre on my iPhone 13?

OK. Swipe down on your home screen from the top right hand corner, to open Control Center. Look for the Bluetooth Symbol and tap it to turn off Bluetooth. NOTE: this will disable Bluetooth but it will turn back on the next day on its own. If you want it permanently off, open Settings > Bluetooth and turn it off there, where it will remain off.

if you turn it off there then it will reenable after 24 hours or so at least that is how it used to work

if you wish to permanly turn it off then you need to do so in the settings under well bluetooth

if your post is that you wish to turn off bluetooth in control centre and it's absent then there you can add it to control centre by following this
