My battery of iPhone 3GS was completely out of order.

My Problem

My battery of iPhone 3GS was completely out of order.

Now I've got brand new iPhone 3GS.

I am using it for 3 hour in a row, however, my battery level is still 100%.

Thanks a lot, ifixit!

My Fix

As a guide of "Installing iPhone 3GS Battery" (without pagination ;-) I 've been replacing my battery. Now I have "a" brand-new iPhone 3GS. ;-)

My Advice

"Don't touch..." sticker was very tearable. You need much patience.
