Trouble charging iPad
So, lately, whenever I try to charge my iPad, it says either "Not Charging" or just shows the battery percentage as if there wasn't even a charger plugged into it. I'm using the charger and block that came with the iPad so I don't know what to do! I have also tried using Low Power Mode. When the battery charges it charges slowly, like 1% per 3 minutes. Do I get a battery replacement? Or do I get a new charger?
