Frankly, LTE kills batteries. Fast. Often times the hit battery takes makes LTE is not worth turning on at all.
But the Razr Maxx has an enormous 3,300 mAh battery that allows you to browse on. And on. And on.
Everything that makes the Droid Razr so amazing is in the Droid Razr Maxx. The only compromise is the thickness of the device, and what you get for it is a whole lotta battery.
Unlike most LTE phones that don't even last seven hours, the Motorola Droid Razr Maxx allows you to browse on LTE for seven hours. Or talk for 21 hours. Or watch videos for 15 hours.
In other words, it's the world's first LTE phone you can use like a normal phone.
If you absolutely must have an LTE phone, and you absolutely must use 4G speeds at all times, the Droid Razr Maxx is the snazziest phone you'll find.
