Too many thread that lead to nothing. I want a professional opinion based on this info: iPad air has a7 and a higher resolution, yet everything seems flawless. iPhone 6 plus has smaller resolution AND a8 yet people continue saying it lags (whether it's true or not i don't really know, mine arrives Wednesday and I still haven't decided if i want it or i want the 6) What i want to know 1)Could it be software? Or is it the scaler to blame? 2)Can it improve? Or the scaler is eating all the power? I don't care about games (or care but very little), i care about iOS 9 and iOS 10. Will this be a problem? Please, reply ONLY if you really know what are you talking about. Specifically.. How the scaler works and if it is indeed eating all the resources. I just can't find a plausible explanation.. why iPad air with a7 and higher resolution would work better than a8 and a smaller resolution.
