People experiencing battery issues need to note a few things:
1. First, use only official Apple chargers and cords. Why wouldn't you? It came with them.
2. Your battery life degrades over time(especially if you abuse it, i.e, run it flat or trickle charge it overnight, every night). These batteries are a couple years old now. A new Ipad3 battery takes 5-6 hours to charge. Leaving it trickle charging all night long every night is not recommended, and it will reduce the life of your battery.
3.. My Ipad3 battery still runs strong, charges to 100% in 6 hours, and holds it's charge. How? Well, I charge it only when it needs it and I use the official Apple accessories that it came with. I run the battery to around 5% and then I charge it(during the day) to 100% and immediately take it off the charger. At night, I turn my Ipad off. Do you need your Ipad running while you sleep? Apps and resources are still being used when your Ipad is not in use. Turn it off when not in use. Also go to Settings>General>Background App Refresh and turn it off.
