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 5,000mAh battery, which is expected to yield a long battery-run time. 

The G7 Play and Power cost $199 (which converts to £154 and AU$280) and $249 (£231, AU$421), 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.
