Will 12W charger charge iPhone 6 Plus any faster?

Impossible because it doesn't happen. The iPhones only pull 5 watts regardless of what you think.
I charge my iPhone 5 quite often with a 10W iPad charger. A couple of weeks ago I noticed that my screen was starting to pop out of the chassis at the top. I took it in to the Apple Store and they discovered that my battery was swelling. I don't know if the iPad charger caused this, but I know that I am not going to be charging my iPhone 6 Plus with the iPad charger anymore.
No it makes you the liar. Unless you can show me proof the iPhones do in fact charge at a maximum 5w in official Apple documentation, the maximum wattage the iPhone can handle can be anything from 5 to 12 or even higher wattage.
Yes that I am correct.
iPhone plugged into a Macbook Pro. 500mA (standard USB max) + 500mA (extra) = 1000mA
1000mA * 5V (standard USB voltage) = 5 watts
iPad plugged into the Macbook Pro. 500mA (standard) + 1600mA (extra) = 2100mA
2100mA * 5V = 10.5 watts, maybe the iPad can take more but the Macbook can't provide it. But this shows that the Macbook is capable of providing extra current but the iPhone (5) doesn't want it.
Updated with iPhone 6+ screenshot (courtesy of ToroidalZeus) - confirmation that iPhone 6(+) charges faster from Macbook or iPad charger versus 5W wall charger!

CAN a 12 watt charger charge faster? Absolutely, but WILL it depends on the phone itself. If Apple has designed to to draw more than 5 watts then yes, if they have a 5watt cap on it, then it won't. The rate of charge depends on BOTH the charging unit and the device being charged when we are talking about iPhones
If the phone is powered off, 12w will not charge the battery any faster than the 5w. The phone sets the max current it will pull. However, if you have the phone on and are running background tasks, it WILL charge faster because those apps are pulling current away from what would otherwise be allocated to charging the battery.
The battery has a max charge of x. The apps use y. The 5w provides the x current. The 12w provides x + z current.
So if the phone is off, the phone will pull the max current, x.
If the phone is on, the 5w provides the full current x, but y is pulled away for the apps, so you only get x-y to charge the battery. The 12w charger, provides the full current x to charge the battery, plus you have up to z additional to go towards the apps, so the phone will pull x + y (with a max of x + z).
If your charger provides less than x, let's say w, and y > w, you end up pulling power for the app plus y - w from the battery. This happens when I run Waze and have the phone plugged into the car charger. The car USB doesn't provide the full current x.
So the battery isn't charging any faster, there's just more power available to charge and do other things.

This is the best explanation I've heard so far as to why people experience faster charging when using a 2.1 Amp charger.
Nice find.
It's not a matter of what I think. It's a matter of fact. And your facts are not that they are opinions. And it's all in your head.
The iPhone dictates the power draw@ 5 watts. This has been proven time and again. And you can't change that no matter how many times you state it as fact on the Internet.
That being said this may have changed in the new 6 and 6 plus.
This page (and related pages on the site) describe how the iPhone 'tells' the charger what it is and has the charger provide a certain amount of power.

You'll notice that according to the facts on this page, a 12W Apple Charger will provide only 5W of power to an iPhone because that's what the iPhone asks for. So the question is ... "Will a 5W charger charge iPhone faster than a 5W charger?"

Dude you can think what you like. I couldn't care less
As for your video I wouldn't watch it even for money.
I know what the specs state and what the facts are. So I am done.
As for the Mr know it all wisecrack. Thank you.
No.
It will not.
It doesn't.
They're not. It doesn't.
OK thanks. I opened my mind. However the fact still remains the same it doesn't charge any faster. What happened my mind was open to the idea. Funny how fact and fiction work.
This thread reminded me about this kickstarter project I saw a few weeks ago. Some hardware engineers were trying to hack the standard USB protocol by increasing voltage to 5.5 volts and doing all kinds of seemingly reckless things. They clearly had spent many thousands of dollars on prototypes.

That proves it then, the phones can charge faster on a 10W (and possibly 12W) charger. Guess we'll need to use Yosemite to get the extra current from our macbooks
