Does your Iphone charges more quickly with Ipad charger ?

I use my chargers interchangeably and have no idea at this point which is which - iPad vs. iPhone. I plug them in at night before bed and unplug them in the morning, all charged and ready to go. Never seems to be a problem for either.
But that was not the question being asked. The question was whether or not the iPad 10w charger would charge the iPad any faster than the standard iPhone charger. And from my personal experience, I'd have to say yes.
My guess would be because the iPad charger is almost 4 times the size of the iPhone charger. Wouldn't fit properly in the iPhone box.
It does charge a bit faster in the beginning. After a certain point the current will naturally drop since the battery can't draw as much at higher charge levels (that's why it's so much faster to charge the first 80% than the last 20%)
Also guys, 1 ampere (abbreviated as amp or A) is a unit of measure for current; there's no such thing as "amperage"

My iPhone is usually charged from a USB port on either my MBA or Mac Mini. Just curious if anyone knows how much faster/slower this is than with a charger?
Charging through a USB port on a laptop/computer takes roughly twice as long to charge than a wall charger.
FYI: Also, The iPad charger is 10W. Notice I stayed out of the main discussion.
The iPad charger is 10W, but if you notice, they mentioned Voltage, not Wattage. It is a 5V output (10Watts/2Amps).
Yup, what he said.
They're all 5 volts including USB from your computer. They just differ in available current.
iPad - 5 volts * 2 amp = 10 watts
iPhone - 5 volts * 1 amp = 5 watts
USB - 5 volts * .5 amp = 2.5 watts
These are all max currents. The iPhone can handle more than 1 amp of current when it's fully depleted so it will charge faster with the iPad charger. But as it gets charged/full, it draws less and less current so for a topping off charge, I doubt the charger makes a difference.
Here's what the current draw looks like for a LiPoly 4.2 V battery charging:
The cable is the same. The iPhone Power Adapter is much smaller (shaped like a cube). When you look at an adapter it has the information on it.
From the last two iPads they're labeled "10 W USB Power Adapter" (which is why I mentioned it earlier). In very very very small print it gives the output as 5.1 V / 2.1 A. On an adapter that comes with an iPhone the fine print says 5 V / 1 A.
That's not my experience. When you say calibrate do you mean letting the phone run down to zero percent once a month as Apple recommends?

As long as you also drain it 15-20% in the same month, yes. It just needs to total 100% once a month.
proof please!
i use my iPad charger in the bedroom and the iPhone charger is downstairs... somewhere...
i have used the iPhone charge on my iPhone the first time, but then i just used the iPad charger next to the bed overnight.
what i have noticed as a marked difference, but i don't know if its due to the charger... is that my battery life compared to other users is simply magnificent!
i have a usual "away from charger" time of 18 hours, and at the end of the day its unusual to have less than 50%.
around once a week i tend to let it run off charge overnight, to drop as low as possible and then charge to 100%.
this i have done for the entire 2 year contract, and i have never had an issue.
upping to the 5s i have followed the same routine, and i took a test (as everyone i know lives on >20% battery, and mine lasts for easily a day, 24 hours and 9 hours usage and 33% battery remaining. leaving overnight i lost 2% for 8 hours sleep and then a further 6 hour usage before 1%.
i have no idea if the 2A charger is the reason for having decent battery life, but I'm sticking with it!!
also, iPhones have a current limiter, so if you plug too much in it will deflect / draw so much... saying that if you plonk a 50A charger into it, it'll probably fry... not charge in 2 mins...
