My iPhone wouldn't hold the charge at all, so I brought it here to diagnose what is most likely a battery issue. They replaced the battery for $70. One week later and my phone is doing the exact same thing it had been before it was replaced. Intact worse- it would go from full charge to 1% which it had never done before that. I bring it back and they tell me it must be a "motherboard" problem. Can't help feeling super ripped off. Seems like a big scam.
