Whatever. Bottomline is you have no proof that this can give 2x the battery life to games. So you are still making stuff up.
Im overexaggerating a bit by when I say 2X, but from experience, playing a game like Vainglory on Wi-Fi, multiplayer games online with my brightness at 60%, i literally have been able to play for over 4 hours and a half until my 6 Plus died, (on a flight) I bet it I was playing offline on Airplane Mode I would of got even more run. So the Note 4 gets roughly on average 3 and a half hours of gaming or so, and the 6 Plus can get over a hour and a half extra of gaming depending on the type of game and if your playing online

The more significant boost on the iPad Air 2 is the GPU. Right now, there aren't many mobile applications that can make great use of multiple cores. Dual core is beneficial since the OS can use one of the cores while an active app uses the other. Perhaps Android can make somewhat better use of a 3rd and 4th core since it permits more multitasking by third party applications, but that's at the expense of battery life. If Apple can match or exceed the performance of quad-core processors running at higher clock speeds with a lower speed dual-core, it's better given the current state of mobile applications and technology.
Apples choice of going with a 3rd core makes a ton of sense and really in essence, would be and will be alot easier for developers to be able to utilize all the cores in a iOS setting then persay Android, since developers on iOS are not dealing with 10 different quad core SoC's and a few different octo cores,etc , deveoping and optimizing their app to all these SoC's employed in Android devices
Apple is focusing on strong single core performance and IPC, and ever slowly but (surely) making its transition to quad core design eventually (who knows honestly, Apple might honestly even make the A9 quad core finally next year on a 14nm node)
Im thinking the 6S will have a tri-core 14nm CPU with 2GB of RAM. a new/better architecture based on ARMv8.1 on a 14nm node with a 3rd core and slight clock bump again (probably 1.4 ghz to 1.5 ghz per core) and that would give it it's 2x cpu gain Apple usually claims every year(and delivers on those claims)
Its either that, or Apple is going to basically double the cores in the A9 on a 14nm node with 2 gb of RAM with some slight architectural tweaks again and obviously better ISP/other functions (4 "enhanced cyclone" cores at 1.5 ghz)
