Just wanted to wake up this old thread because the Slim S3 extended battery is now available in U.S. I picked it up last month and haven't looked back. It really makes a huge difference particularly for those of us that use to get through the day, but with our fingers crossed. This is the way to go for anyone wanting extra Juice without turning their phone into a brick. Amazon.com: Genuine Samsung Galaxy S3 i9300 Extended Battery Kit 3000mAh + Blue Cover: Electronics. There is also a TPU case by Diztronic that comes in a variety of colors Amazon.com: Diztronic Pink GlitterFlex Extended Battery Flexible TPU Case for Samsung Galaxy S III (Works with Genuine Samsung 3000 mAh Extended Battery Kit Only) - Retail Packaging: Cell Phones & Accessories . I personally go naked. Extended battery cover and weight actually improves the grip of the S3.
Anyone by chance use this extended battery with the Superleggera Pro case for S3? I've got the case new, but don't want to open package unless it'll fit this extended battery. Thanks!
The 4200 battery is HUGE though. I keep too much in my pockets to justify that.
Anyone have any thoughts on the size of the 3000? Maybe a comparison of about how thick it is? For instance the Bionic slim extended literally only added about a credit cards worth of width. It was amazing.
