The Motorola RAZR Maxx is a smartphone designed with a high battery capacity. The original RAZR Maxx was made available to the public in early 2012 (read a review of the Droid RAZR Maxx), and Motorola followed-suit with an updated version called Motorola RAZR Maxx HD in October 2012. Both version feature a huge 3300mAh battery capacity, which was still the largest for a smartphone when the Motorola RAZR Maxx HD was launched.
