The phone features a 5-inch HD LCD IPS screen, coated with Gorilla Glass 3, Google Android Lollipop 5.0 operating system, a Qualcomm Snapdragon 400 quad-core processor clocked at 1.2 GHz, 1 GB of RAM, with a "splashproof" coating, curved backing, and front-mounted stereo speakers below and above the screen. The Moto G has 8 GB of internal storage, which can be expanded up to 32 GB with a MicroSD card. The Moto G 2nd Generation supports 2G and 3G connectivity in all its variants. It is available as Single SIM model. The device includes a non-removable 2070 mAh battery, which Motorola touted as having "all-day" battery life. The Moto G features an 8-megapixel rear-facing auto-focus camera; the device includes a flash and a front-facing 2-megapixel camera. The device is available in either black or white front colors, and has an interchangeable rear cover with different color options.
The phone is closely related to the Motorola devices Moto X and Moto E; although there are some key differences despite their similar appearances. The Moto G does not have active notifications, quick capture, and touchless control like the Moto X due to the Moto X using a special processor that would be cost-prohibitive for the Moto G. However, the phone gets the Ambient Display feature in the Lollipop update, but it only works for new notifications. Unlike the Moto X, the Moto G has a removable back cover so that users can customize the phone in whatever color they want; although the Moto X has its online Moto Maker that also allows the user to customize their phone, the casing on it is permanent instead of interchangeable like the Moto G.
