iPhone battery drains wicked fast, even at 100%?

[Neeliosis]

Even at 100%, the battery dies in about 20-40 minutes. I tried restoring about 5 times, no luck. I got the phone replaced about 3 months ago, so it hasn't hit the 300 charge cycle, but I read somewhere that Apple charges you for it. The iPhone 4 is obviously still under warranty. So will Apple replace it for free?

EDIT: I close out my apps in Mutlitasking, so that's not an issue either.

Unless I am mistaken the iPhone 4 comes with a 1 year warranty so you should be fine. The only time the charge for a battery replacement is when it is out of warranty.

You're jailbroken.

You're jailbroken.

So are you just taking a completely blind guess or are you the next Miss Cleo?
My phone is jailbroken and I get great battery life.

Mine too is jailbroken, and I can confidently say I get even better battery life now, thanks to auto3g.

If you're not under Apple care plan, then good luck. Either they charge for the battery or large amount..

Just restore with 4.1 and go to the Genius Bar. Your phone can be replaced.
