My iPhone 4 won't turn on, how do I get it work?

The battery has completed died but when I plug the charger in it doesn't charge.
The charger is new so it definitely works because I tried it on another iPhone.
It's been like this for 2 days now and on the first day it used to charge for on and off but it didn't make a difference. Now nothing happens at all.
I tried using 2 other chargers and still nothing.
Please help!

Firstly, if the battery is dead, and I mean Really dead, leave the charger in for a while because the phone won't even light up until a few minutes of charging.

If that fails try putting it into Recovery mode:

1.
Open iTunes and connect the iPhone to your Mac/PC

2.
Press and hold the Home button and the Sleep/Wake button at the same time.

3.
After exactly 10 seconds release the Sleep/Wake button. Continue holding the home button until you iTunes pops up a message telling you that it has detected an iPhone in recovery mode.
