I'd abused my battery quite a bit and I needed to change it. I plan on handing this one down for my son to use as an iPod Touch when the new model comes out so why not take advantage and change the battery now while I can gain some of the benefits.
The repair was fairly simple. It was much easier to open and maneuver around the insides than the previous iPhone models I've toyed with. The iFixit.com 54 Bit Driver Kit that I purchased a couple of years ago had all of the bits that I needed for the work. That's a great buy, I use it all the time. You definitely need the spudger and the suction cups. I used the heavy duty suction cups (already had them from a project where I needed to remove the glass from my iMac). It was a little big for the device but it worked. The battery itself was a little tough to remove, the adhesive is fairly strong, but I followed the instructions and got it out eventually. Overall it went very well, I was done in less than 20 minutes and everything is working A-OK. My battery still isn't lasting very long but at least now I know it has more to do with my heavy usage than with the life of the battery.
Don't go by the pictures alone, READ THE INSTRUCTIONS before and during the process! The photos are great and an invaluable resource but the wisdom offered in the text is of UTMOST IMPORTANCE. I found myself on the verge of breaking something a few times when going by the photos alone. If you read the instructions then likelihood of doing damage to your device will reduce significantly.
