The Zino 2 Plus is pretty much a very slight upgrade from the Zino 2, in which Hubsan has optimized and tweaked some things like the battery life and range and added a few new flight modes.
The battery of the Zino 2 plus isn't necessarily bigger, yet it can fly for 35 minutes (36 min hover) compared to the 33 min (31 hover) of the original Zino 2.
Flight modes
The new Zino 2+ has a few additions to the mix:
Dronie - drone flies away from you and takes a video Fly to the sky - it flies above you and far away IMU calibration - ability to calibrate the GPS better And here are the original flight modes:

The drone also comes with optical flow sensors at the bottom, allowing for a more stable indoor flight (if there's no GPS) and visual landing support, where the drone adjusts the trajectory to land more precisely.
