Its understandable- everyone wants their cellphone to complete the journey of the desktop- but the battery is just to bad. Even with a dedicated chip for drawing - open pubg and the batterys power-supply falls like a rock.

What is a game other- then a lightshow- No-Sleep-Bug?

In my opinion, as long as there is demand and physics unaligned, "building it and they will come" will not archive anything.

So why not instead build a miniserver with gfx cards into WiFi and do the computations for AR, VR and games (mostly downstream data) and catch that with a passive WiFi-Reciever? It is still video displaying - but it does not come with the usual computational burden.

I know, that is a bad architectural choice - away from the expected model, that should batterys get good, would triumph any day now. But if you plan in for that eventuality - you can still program architecturally near neutral and you could walk ahead into the future, not just glimpse it while tied to a charger.
