Is their a way to charge iphone 5 faster?

I must admit the iPhone 5 chargers pretty fast! But are their any ways to make it charge faster? Such as airplane mode or something?

Turning your phone off while charging decreases the charge time. The less energy you use while charging. The faster it charges.
Either that or you can overvolt your charger. Which may cause it to melt and I highly recommend not doing that.

The best method is to turn the phone off totally. There may be other methods using third party products but with prematurely burning out the battery.

This may sound stupid but there's a rumor that you can microwave your phone to charge it. I would look into it before actually trying it though. But i'm just sayin its a possibility
