Deeper sleep on MacBook so it will stop connecting to bluetooth and draining battery I have the Sony MX1000 Bluetooth headphones, that can only connect to 1 Bluetooth source. So after work I put my MacBook to sleep, and would like to connect my headphones to my phone. This is not possible though, because my MacBook is still holding on to it, draining it's battery in the process. 

To stop my mac from keeping its connections open, I tried this solution where I set stand-by mode as the default with sudo pmset -a hibernatemode 25 and then invoke it with  Command+Option+Eject (Computer sleep), but it didn't work. The bluetooth stays on. 

Does anyone have any other ideas?
You could install blueutil and SleepWatcher via homebrew and set a .sleep code to do "/usr/local/bin/blueutil -p 0" in order to disable bluetooth when going to sleep mode. I had the same issue and this did the trick !

To use SleepWatcher: make a shell script in your home directory named .sleep and give it permission with the command chmod +x ~/.sleep.

You also can do a .wake code to turn bluetooth back on with blueutil -p 1 when waking up.
You can find out how to use SleepWatcher here 

You can do all of this with Keyboard Maestro too, if you prefer a GUI tool. You can have Keyboard Maestro call blueutil to control your Bluetooth. However, the first thing to do is make sure that “Enable Power Nap” is OFF in System Preferences under Energy Saver.
