The S Pen is far more capable than ever before. It now has Bluetooth Low-Energy, meaning you can use it to control the Note 9 up to 30 feet away. You can do things like control presentations, take selfies or group photos (without having to touch the Note 9), or control music playback. You can customize what the S Pen’s button will trigger through the Settings menu on the Note 9.
**While this does mean you have to charge it, the built-in supercapacitor battery in the S Pen only needs 40 seconds in the Note 9 to give it 30 minutes of charge.**
