After two years of faithful use my battery was acting erratically and dying without warning. Since I want the phone to last another 2 years and I don't want to constantly carry around a charger I decided to replace the battery.
It went well overall. Popping the sucker open was pretty nerve racking - it takes a good amount of force! Also, removing the old battery was a challenge. My phone started right back up after putting it together. I noticed, however, that there was a slight discoloration at the top of my screen. I think that I loosened a cable between the screen and the back of the phone. I pried it open again, nudged all the connections, and the problem has been largely eliminated.
Be SUPER careful with the connections to the screen. One of the 'bands' is a flat connector that can be accidentally pried from its intended location.
That being said my new battery is working like a charm! I can make it through a day of medium use with over 50% battery! No lugging around cables or bumming chargers off my friends anymore!
