is a better source about Samsung Galaxy S3.
@Skylit: That isn't necessarily Samsung's fault. It is the U.S. carriers fault because they want something unique to their carrier. Which is why they look different from the original Galaxy S2.
The specifications for the SGSIII are of course subject to change, but are Samsung-developed 2.0GHz quad-core CPU (no codename given), 1.5gb RAM, 32gb internal memory (with sd card slot), and a 4.65 inch screen. A new display called Super AMOLED III is being developed specifically for the phone (SGS had Super AMOLED, SGS II had Super AMOLED Plus, SGS III has Super AMOLED III) with 1280x1024 resolution, giving the phone a ppi of 352, which they emphasized that a 352ppi will make it the highest ppi mobile phone.
The device also “has a 2250 mAh battery, 10 megapixel camera and is capable of shooting 1080p video at 60 frames per second,” and “will come with an inbuilt NFC chip.” We are yet to see how much juice a device like this would suck out of a battery, but 2250 mAh sounds like it should get you through the day easily.
So, no.. it wouldn't have bad battery life. And this is all speculated rumors.
