Motorola made the decision to resurrect its most successful mobile franchise and give it the Android treatment. The end result would be the Droid RAZR. While the phone donned one of the sleekest industrial designs every seen on a smartphone and high-powered specs, battery life (like the compact models) was considered its kryptonite. Three months later, it welcomed a newer version—one equipped with a 3300 mAh Li-Ion battery and featuring Moto’s game-changing Smart Actions software, which designates commands to preserve phone vitality up to 30 percent. Mark our words: greatest battery-life phone ever!
