Motorola Mobility (GOOG) refreshes its Droid lineup ahead of its Aug. 1. Moto X event. The 5" Droid Maxx is the highlight: aided by a giant 3,500mAh battery, Motorola claims the Maxx delivers 48 hours of continued use (the current Razr Maxx boasts 32 hours). The Droid Ultra is slightly thinner and offers less battery life, and the Droid Mini uses a 4.3" display, but the phones are otherwise similar. Much like the X, Motorola is offering features such as voice control and swipe/shake gestures to stand out. Each phone has a 720p display (many rivals are at 1080p). Verizon will sell the Maxx for a steep subsidized price of $300; the Ultra goes for $200, and the Mini $100. In a slight negative for QCOM, Motorola is using a home-grown app processor called the X8.
