Motorola Mobility Holdings unveiled Tuesday a new Verizon Wireless smartphone, the Droid Razr, as it seeks to boost sales in its largest global market.

The phone will be available in November for $299. Motorola will begin preorders Oct. 27.

It will run on Google's Android mobile software and boasts as much as 30 percent more battery life than competitive devices, Motorola CEO Sanjay Jha said at an event in New York.
