I just ordered myself an iPhone 5. Now I am a little worried when I read all these threads from people who have had their iPhone 3, 4 and 5 damaged by an expanding battery... Will the battery expand and damage the phone some day no matter what or does the battery only expand under extreme conditions/because it is faulty? The reason I am asking is because I'm the kind of person who uses the same phone for a very long time and plans on replacing the battery when it is dead to keep using the phone. But if the battery damages my iPhone 5 by expanding when it dies then I won't be able to use it anymore... So what is it, do all battery expand and damage the phone eventually?
