iPad 2 battery, always switches off when it gets down to 40%

Has anybody else experienced this or similar, your ipad 2 suddenly switching itself off when the battery gets down to around 40%? Any tips much appreciated!

Seems that it might be related to battery calibration.

Do you charge to 100%?

No, on iPad 1 and 2 my batteries work fine. I get battery warnings at 10 and 5 percent and the iPads auto-shut down at 2 percent.

As bat0nas says, your battery calibrator might be wonky. Apple advises draining your iPad battery once a month to keep the battery calibrator accurate.

If that doesn't work, I suggest you consult Apple. Your battery should still have plenty of life even if you've used your iPad 2 a lot in the past year or so that iPad 2 has out.
