I don't understand what it patentable about these things. All of the functions described currently exist in devices on the market. The only possibly unique thing is how Nintendo will implement them. As far as I know differently combining existing technologies or functions isn't patentable.
Even operating at different power levels is a thing, albeit devices don't have discreet power set points but rather change power consumption dynamically depending on the processing load being placed on the device.
