My Iphone will only charge to 3%, then goes back down to 1%. When it is 'charging' it does not say it is and will not go any higher. I have reset my phone, restored it, turned it off mulitple times and nothing will fix it. Also, I have tried 6 different chargers and muliple outlets, and tried plugging it into my laptop and it still wont work.
This means either the charging unit or the battery is done. If your phone has warranty left, contact the closest Apple store near you & make a appointment with the Genius bar. Have them look at it & they will most likely replace it with another iPhone ( same model as yours)
If your phone has NO warranty left, you will need to pay to get it fixed & the amount is something Apple or any cellphone store will give you as on here no one knows whats wrong with the phone.
