About the only thing that makes sense is using APU that can deliver docked performance in hand-held mode.
Probably as option you can turn off, in favor of better battery life.
Really there is huge room for improvement because they didn't even use standard 14nm process even cheap Androids do.
That process alone offers ~30% power/performance benefit from my understanding, which along with other updates
could probably allow same performance as docked while in hand-held mode (if resolution isn't increased, even more easily).
