Usually, about once per month, you need to recalibrate the battery sensor. To do this, let the device run down (out of power) and then charge it up again.
This was a pretty informative article on the issue: http://ipadnerds.com/battery-charging-very-slow-ios-7/
They recommend you use a 12 watt wall charger to charge your iPad. Apparently a lot of people are having this issue.
Using the battery level meter in this manner is comparable to using your car's fuel gauge to calculate miles per gallon. The only thing that matters is the total amount of operating time from full charge to auto-shutdown.
Use the wall-mount charger that came with the iPad and charge overnight. Do NOT use an iPod/iPhone charger. Do NOT use a computer's USB port. Then, operate it normally until auto shut-down (ignore any low level alerts that may appear). An irony is that doing that test to determine the total operating time is also the procedure necessary to calibrate the battery level meter.
I'm not claiming that you do not have a problem. I am stating, however, that we don't yet know.
Use Your iPad Regularly
For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).
Elsewhere, Apple elaborates and explains that two half-discharges (or four quarter-discharges, etc.) equals one full discharge.
