Hardware & Performance
Moto Mods modules are the killer feature of the Motorola Moto Z smartphone. They snap onto the back of the device, augmenting its functionality - by adding a projector, a stereo speaker set, or simply a huge battery, for instance. Or you can simply use a stylish back plate with natural leather, wood, or fabric finish. As far as specs go, the Moto Z is a beast, boasting plenty of memory and the fastest chip Qualcomm has in stock. All that hardware, along with the 13MP camera and 2600mAh battery, is packed inside a super-slim, metal-made body. Expect seeing this phone on Verizon's shelves in the US.
