The Motorola Droid Maxx is the classier cousin of Droid Ultra, and these two Android smartphones are members of Verizon Wireless' fall 2013 Droid lineup. While the Ultra was a slippery and shiny phone, the Maxx stays true to the Moto Droid heritage with it's zigzag patterned matte Kevlar back. The Maxx is the long life phone in Droid land, and it features a 3500 mAh battery, which is the largest battery you'll find in a non-phablet phone. The Maxx maximizes storage too, with 32 gigs vs. 16 on the Droid Ultra. It also has wireless charging.
Beyond that, you're looking at the same features as the Ultra. Is the Maxx worth the premium $299 on contract price? The answer is yes if you need lots of battery power on the road. Of course, the Droid Maxx competes with the Samsung Galaxy S4 that doesn't match battery capacity, but it does have a removable battery so you can swap in a spare.
The Droid Maxx has a 5" 1280 x 720 AMOLED display, 1.7GHz dual core Snapdragon S4 Pro CPU with custom processors to handle voice recognition (Moto calls this their X8 processing platform), 2 gigs of RAM, 32 gigs of storage, WiFi 802.11n, Bluetooth 4.0 LE + EDR, NFC, a front 2MP camera and capable RGBC 10MP rear camera. It's just a tad thicker and heavier than the Droid Ultra.
Like the Ultra and Moto X, it has Motorola's active notifications, always-on voice command software and Moto Assist. It also has Droid Zap for wireless photo transfer and the usual bad robot collection of angry red-black wallpapers and a screeching startup sound.
