The M6 ships with a 5000mAh battery and the M6 Plus packs with a 6020mAh battery. Both have 9V/2A fast charging support with a dual charging chip.

By embeding with low power consumption components, including power-efficient displays and chips, and also the smart power consumption management software operated under Android Marshmallow with Amigo OS 3.2 on top, the company promised the M6 Plus could be continually used for two days without being charged.

Both phones are equipped with infrared sensors on top, but the M6 Plus doesn't provide the frequently used 3.5mm audio jack.
