We expect to find out more about Samsung’s new flagship phones and features starting at 1PM ET on January 22nd.

On the Galaxy S24 Ultra and previous Ultra Samsung flagships, the S Pen communicates over Bluetooth and Bluetooth Low Energy. It is also an active stylus, unlike many aftermarket offerings, enabling support for features like Air gesture controls and the ability to act as a remote shutter for the camera.

Attempting to look on the bright side, having no Bluetooth will have a small impact on the phone's battery life, since the S25 Ultra will no longer have to donate power to the S Pen to keep it functional. But given the power demands of an S Pen are so small, this is unlikely to have a noticeable effect.
