Owners say that TSMC A9 SoC delivers two hours more battery life than Samsung’s A9.
Problems coming for Apple. This doesn’t make much sense: TSMC chips are made with 16nm vs Samsung’s 14nm. That would benefit the latter in efficiency and raw power but the tests show exaclty the opposite.
I wonder if this is some kind of weird support for the chips at the kernel level in iOS 9. Let’s see what Apple has to say (and do) in this regard.
