Went to the Genius Bar yesterday since my iPhone's battery isn't good at all. The phone is kept in a case, no scratches, dings or anything. He ran the tests and battery status came back as "normal". He then points out the overall average usage I'm getting out of my phone is 4h 16min. He emphasizes that this is below average from what I should be getting. I was expecting that his next words would be "I'll go ahead and exchange the phone for you" but he didn't say that. He said that since there is no physical damage to the phone that he can't exchange it. It's an iPhone 5 purchased a month ago. I don't feel entitled to a new phone nor did I demand it, but I was pretty disappointed that they didn't exchange the phone after acknowledging that the battery performance was below average. Has this happened to anyone else? Why wouldn't they exchange it?
