I have a problem charging my iPad while I am using it. Thus is a little diffrent from other people's problem with charging. Anyways, when I leave the iPad charging, it charges. But when I am using the iPad and charging it at the same time, the percentage just goes down slowly and not up. I have reset my iPad, got a new charging cable, replaced the battery. Still same problem. By the way, when I put the new battery in, I noticed it did go up while charging and in use for like a day or 2. That was after I replaced the cord also. So both was bad. It is about 5 years old I think. I still have this charging problem. I do not know what else it could be. Help. Thanks in advance.
