If the 1650mAh battery in your Samsung Galaxy S II just isn’t enough to get you through the day, then it looks like you’ll want to be buying this new 2000mAh battery when Samsung release in Australia come September 29th.

The battery is 110% official, so there’s no worrying about a crappy knock-off that might explode. The only downside is that the new battery comes with a new back cover which makes the device ~1mm thicker (~9.5mm) but that’s a fair trade-off for an extra 350mAh of juice.

It’s priced at $40 which also isn’t too bad — I’ll be getting one, I reckon — and will be available from Samsung Australia’s official accessories site. Go on, click the source link, you know you want to bookmark it.
