I have the opposite experience: GrapheneOS has an option to automatically turn your bluetooth off after a configurable period of not being used. So when I need to use bluetooth, I turn it on like normal. Then, without thinking about it, it automatically turns off. The end result is my bluetooth is only ever on for a couple hours each month when I'm making phone calls.
I only see an option to turn back on tomorrow. How do you find this option?
It's under Settings > Security and Privacy > Exploit Protection > Turn off bluetooth automatically
Definitely not the most obvious location. I would have expected to find this under the bluetooth settings.
Did not realize I could do that! Thank you!
