Was wondering. iPhone 4 charges upto 100% in few hours. iPad 3 charges 7-8% per hour. So from 0 to 100% takes 14 hours to charge the battery. Is this normal? Device has been in use for about 2 months. Like right now as typing this and plugged into wall, charge dropping (3% so far). So in conclusion wifi connection taking more power then the wall outlet can provide? Someone please give me answer before I complain to store that sold me this. Or is this normal? Kinda understandable as if battery life 10 hrs and 14 hrs to charge it makes exatly hrs in a day.
