Just in time for the introduction of the iPhone 5, my 4 is taking a major dump on me the past few days. After about 20 months, the battery is finally dying and not doing it in a progressive way. Now, it will go from 100% to under 10% in about 4 hours with no talk and minimal texting. I'm going to get a replacement battery to get me through the next couple of weeks before I can get a subsidized iPhone 5.
