Apr 2, 2014 6:24 PM in response to LauraMackieby Philly_Phan,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. If the above test does, in fact, indicate a problem, read this.
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.

Apr 2, 2014 6:26 PM in response to LauraMackieby Texas Mac Man,Could be the charger, cable or iPad. Plug the USB cable into your computer. It may say "Not Charging", however, it is charging slowly and will verify that the cable is good.
Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery

At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

In rare instances when using the Camera Connection Kit, you may notice that iPad does not charge after using the Camera Connection Kit. Disconnecting and reconnecting the iPad from the charger will resolve this issue.

Apr 2, 2014 7:30 PM in response to Texas Mac Manby LauraMackie,Thank you everyone for all the suggestions. I always use an official apple wall charger, but I just rebooted the ipad by holding the home button and the sleep button so we will see if that helps. I'm working through reading all the suggestions too so thank you. I'll let you know the results.

Apr 4, 2014 9:45 PM in response to LauraMackieby LauraMackie,Well...after doing everything possible posted here, the battery drain is still horrendous. It's ok on standby but the minute I start to use it, it drains very quickly. 90 minutes ago it was at 100% and it's now 65%! This never happened before this latest update. What a disappointment. Not sure what I should do now. I'd love a new ipad but we can't swing that now. :(

Apr 4, 2014 9:58 PM in response to LauraMackieby sberman,Really? This is the behavior you see after doing all 8 numbered tips in the article, as well as the non-numbered tips at the bottom (turning off Bluetooth, etc.)?
I'm surprised.
Perhaps an Apple Store or Authorized Apple Service Provider would tell you about your battery status. Perhaps it could be replaced.
