The Droid Maxx maintains a similar design shape to its predecessor, the Droid Razr HD, including the Dupont Kevlar unibody form. It included Motorola's proprietary X8 Mobile Computing System, which consists of 8 cores: 2-core Qualcomm Snapdragon S4 Pro applications processor, 4-core Adreno 320 graphics processor, 1 low-power core for natural language processing, and 1 low-power core for contextual awareness processing to enable the new Touchless control feature. The internal battery was increased in size to 3,500 mAh. The on-screen buttons for back, home, and multitask functions were moved to off-screen capacitive soft-keys below the screen. The Droid Maxx also includes Motorola's Active Notification feature.
