Lenovo is working on a new Yoga convertible that will be powered by Android and offer 15 hours of battery life. The upcoming Yoga Book doesn't use Windows 10 like some other Lenovo convertibles and it can function as an Android-based tablet or laptop. It can also be put into "tent mode" using its 360-degree hinge.

Other Android-based Yoga devices only come with kickstands, limiting their transformability.

The Yoga Book reportedly uses a 10-inch 1080p display, an Intel Atom Cherry Trail processor, 2/4 GB of RAM, and 16/32 GB of storage. It'll only be 10 mm thick when closed and it will offer fast charging.
