Any hope of Apple making the Bluetooth toggle a true on/off?

Apple made a conscious decision to change the function of the Bluetooth switch. While Bluetooth does not need to be turned off generally, the Control Center switch will turn it off it it is temporarily needed to be turned off. Siri will turn it off, or you can go to Settings. You can provide feedback to Apple if you would like to share that you want to see a change, Feedback - iPhone - Apple but that does not mean that they will change it.

I hope they NEVER change the outstanding way it now works. There used to be 4 ways to turn off Bluetooth and Wi-Fi completely. Now there are still 4 ways to turn it off completely, and one additional way to disconnect temporarily with the button on the Control Center. If you really want to turn it off (and there is rarely any reason to) you have:

• Settings/Bluetooth - OFF
• Touch Settings, tap Bluetooth on the floating menu that appears - OFF
• Hold the SIDE button and say “Turn off Bluetooth"
• Say “Hey Siri, turn off Bluetooth"

First of all, your rant won't be read by Apple. This is a user only forum and none of have any inside knowledge of Apple's design decisions or future plans.

It stands to reason what you want is not in keeping with the Bluetooth decisions Apple made some time ago. The feature to turn off Bluetooth in Control Center was clearly designed as a temporary turn off. But the ability to turn it off completely (though I'm not sure why you feel you need to ever do that?) is still available in Settings > Bluetooth.

Ps: I too hope they don't change this as the ability to temporarily turn off Bluetooth from Control Center is actually VERY handy when dealing with multiple BT devices.

Turning off BT won't have much effect on your battery life:
