Depends on which battery you bought; I'm guessing it was an aftermarket one - there are lots of 'em flying around only some of them are better than the stock one.

Don't just believe the mah they state on the battery.

i'd check this thread, a lot of good stuff written on buying high mAH batteries of places like ebay.

Thank you for this post
There are some people who have had unpleasant surprises when changing battery
I was wondering about batteries made ​​in China.
I will focus on a battery where there will be a good return, like your 1800 mah stock ;)

Get the samsung galaxy S2 Epic 4g touch battery. 1800mah and fits perfectly.

I have a chinese battery (otb original) and, when it's some hours power the phone with that battery, is like if I'm making long press on home key, and constantly jump the window with last open applications. As if it were a charged capacitor...

Many of the batteries you can find on ebay etc are fake. The mAH is just a sticker and easily printed
A fairly good/simple way to test is to weigh the batteries. If the new battery is lighter, it almost definitely is fake.
Another way is to peel off the sticker. Usually the manufacturer will print the actual capacity on the aluminium thing under the sticker (I peeled off the sticker of a 2.99 battery that was '1500' mAH - said it was 1000 underneath).
