Why is my iPhone charge going down while it's plugged in?
My iPhone's battery charge is going down while it's plugged in to my car charger. It only does this while I have the Maps app running, and as soon as I close down the app it begins to charge again.
I use this app fairly regularly and haven't had problems charging and using the app at the same time until now. Is the GPS app somehow using more power or is my battery faulty?
Es esta una buena pregunta?
