Would this battery work on a Focus?

Samsung now offers a bigger battery for the Galaxy S II, makes it hard to battle your smartphone addiction

I only ask because I know some Samsung batteries are universal. There's a couple ones you can use on a Focus from their Android lines.

well, since the original battery in the Galaxy II is a 1650mAh, and the original in the Focus is a 1500, the 2000 is likely quite a bit thicker (1.5mm thicker than the 1650), and with the battery flush to the Focus case as it is, it's very doubtful you could shoehorn that in and get the cover on.

so, try this one out, it comes with a new battery compartment! Newegg.com - Black Extended Battery W Door (2400mah) For Samsung Focus I917
