According to Venture Beat, these add-ons will be called "Amps" (LG calls them "Friends”", and Motorola already have six ready for launch. Each Amp brings the following additional feature: stereo speakers, extra battery, a camera grip with optical zoom and additional flash, a wide-angle lens attachment, and a projector.
The dual-phone release includes a "premium" flagship phone and a less powerful phone aimed at the mid-price market. The Vector Thin is the top dog here, with a 5.5 inch Quad HD AMOLED display and a Snapdragon 820 processor. The Vertex runs Snapdragon 625 and a 1080p HD display. The Vector Thin also features a 16-megapixel camera to its smaller brother’s 13-megapixel. Both phones have fingerprint scanners.
The more powerful Vector Thin has a much smaller battery (2,600 mAH) to the Vertex’s (3,500 mAH).
There’s no word on pricing yet, but Android Police reports that The Moto X Vertex and the Moto X Vector Thin will be officially unveiled on June 9 at Lenovo’s Tech World event in San Francisco.
