Lastly, the G7 Play and the G7 Power fall a half-step below the Moto G7. Though they have the same processor as the G7, they only have one rear camera each, and the G7 Play has a smaller, lower-resolution 5.7-inch display. The G7 Power, however, stands out from the whole pack by having the highest capacity battery of the bunch. It features an impressive 5,000-mAh battery, which is expected to yield a long battery-run time. 

The G7 Play and Power cost $199 (£149, or about AU$280) and $249 (£179, or about AU$420), respectively. They will be available in Brazil, Mexico and countries in Europe, Latin America and North America. The G7 Power will have a slightly wider distribution, and Motorola will sell it in India and countries in the Asia Pacific region as well.
