Drone maker DJI has revealed the Osmo Mobile 2, an upgraded version of its stabilizing smartphone gimbal, set to launch through apple.com on Jan. 23.

The accessory's main improvement is a better internal battery, said to offer up to 15 hours of video shooting — more than three times what the original Osmo Mobile allowed. The Mobile 2 is also lighter than before, and equipped with a revised button layout, including a built-in zoom slider.

While iPhone video is normally best shot in landscape mode, the Mobile 2 can also be used to shoot in vertical orientation.

Software-based features include subject tracking, panoramas, timelapses, and "Motionlapses," which are timelapses shot while an iPhone is moving.
