If the iPhone 6S beat the latest Galaxy Note 7 so easy like the video below (which is just a dual-core compared to octa-core), what more with the iPhone 7?
I wonder what kind of optimization and black magic did Apple made with their iOS? I was amazed.
So now I use an iPhone 7 as a daily phone. Compared to my 4+4 core of my HTC A9, iOS has no lags. Oh and the headphone jack is not a big deal for me (yet) since I always hook my headphones to my computer to satisfy my audiophile demands.
