One issue with the MG-X Pro is that it is wireless and lacks a lighting cable plug to connect your iPhone into. This means that there is no power throughput, which becomes a problem when using cloud gaming services, like Xbox Cloud and PS Remote Play, that need a lot of power to stream games. The lack of pass-through charging makes it difficult to play for extended periods, and users must take similarly extended breaks to recharge their phones.
Additionally, the companion app for the MG-X Pro does not offer enough to warrant its download. It offers the ability to calibrate the two analog sticks, but users worry that they could drift in the future, and walkthroughs of what the MG-X Pro is capable of. That’s not all that much.
