Differences in battery information and phones printed labels
mA is not the same as mAh. The former is a current rating, and the latter is the capacity of the battery. 1000 mAh means the battery can supply a current of 1000 mA (at its rated voltage) for 1 hour, or equivalently, a current of 500 mA for 2 hours, etc. It tells you how much energy the battery can hold.

The number in mA printed on the phone tells you how much current the phone can draw. It's like a safety rating, though I suspect the numbers are somewhat made-up for phones: it would be very unusual for the phone to actually draw that much current, and most of the time the amount drawn will be much less.

There's no reason for those two numbers to be the same.
