    There's no bug.

     

    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.  Admittedly the labeling is hard to read but, if you use a magnifier and squint your eyes, you'll see "Output 5.1V, 2.1A."  The symbol between volts and amps is the symbol for DC.  Do NOT use an iPhone charger.  Do NOT use an iPod charger.  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 exact 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 whether or not a battery problem exists.

     

     

     

     

    According to Apple:

    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.

    There is no bug.  However, if you're happier claiming that there is one instead of resolving the problem, that's your right.

    First you are only talking to other users here NOT Apple. This is a user-to-user help forum hosted by Apple. Everyone here is just another user like yourself. Apple does not participate in this forum.

     

    That being said:

     

    Something may have gone amiss in the upgrade to iOS 6.1.2 on your iPad.

     

    To correct this follow these steps:

     

    1. Backup your iPad using iTunes or iCloud.
    2. Use iTunes to completely restore your iPad as new.
    3. Monitor battery usage to see if it is normal. If not, you may have a hardware problem - if so, contact Apple support.
    4. Restore your iPad from your backup taken above in step 1.
    5. Check battery usage to confirm that it is normal.
