I've only had this iPad for 8 months and I looked in settings and it says it takes 32 1/2 hours to charge, it used to only take 4. That's a lil much isn't it?
That's too excessive. Take it to the Apple Store to have them take a look at it. Even I you don't have the apple care, I would think that sounds like a faulty battery possibly. If less than a year, manufacturing faults should be covered. It won't hurt to check.
