They did mentioned what the phone can do, watch the ad again. Nothing wrong with poking fun at your biggest competitor
They actually talked about it quite a bit.
But the point of the ad is just more of the Apple vs Samsung debate. This gets right to the heart of each phone.
I half expect Apple to subtly kick back with "uuuh my phone fits in my pocket with room to spare"
It's all to keep us talking about the device.
Mike: hey did you see that ad?
Bob: Oh you mean the one talking about how Apple users are always charging but Samsung users have the Ultra Power Saving mode and can swap batteries?
Mike: Eventhough Apples can't swap batteries or have the battery life like Samsung they're still awesome.
Bob: ok..... yeah.... I like battery life though.
