Battery was hardly lasting me or my father for a full day, and we have had ours since August 2010. It seemed like this was the most economical attempt to preserve the life of our phones
Easy installation, easy swapping out.
I recommend doing this process on a white piece of paper to see the screws, and with gloves on to protect all the electronics from skin oils. I would love it if iFixit gave us the best location to dispose of the batteries at.
