Just so you guys know, I am replacing the battery in my iPhone 4S exactly one year after purchase. Because in that year I easily did over 300 full cycle charges and the battery is only rated for 400. Which means mathematically my battery is now somewhere around 85% of its original storage capacity. And it was showing before I replaced it with the iPhone 5. When I got the iPhone 4S I was averaging 7.5 hours of use each day. When I retired it last weekend, I was only getting 6.25 hours. 6.25/7.5 = 83.3%.
It ain't easy being an iPhone around me
Skull - now this is something we have to pay Apple to do, correct? You would do this even if your battery has not reached "end of life"? Is it expensive to have Apple replace the battery? Or is that something covered by Applecare in the first two years of our coverage plan?
