I have an iPhone 5 that's eligible for Apple's battery replacement program. I haven't actually had any trouble with it, but I suppose I should take advantage of the offer before it expires. There are two Apple stores in the area, so I'd prefer to take the phone to one of them. But the web page doesn't actually say whether battery replacements are done on site or how long the process takes.
What should I expect here? Would Apple replace the battery while I wait? Would they ask me to leave the phone a few hours or overnight? I don't imagine they'd swap it for another phone, if only because they wouldn't have the original iPhone 5 in stock at this point.
