AC Question

how many amps does my samsung galaxy s3 draw from the battery?

I plan on using this battery to power a device that draws 2amps, since the galaxy s3 is 2100 aMp that means it could only run it for 2.1 hours on a full charge correct? but if my samsung battery lasts for 12 hours it only draws .175 amps which does not seem right at all.
