The Camera
Very important to media junkies who want high quality picture and video capture options. Once again the Galaxy S3 is much better in this field. The S2 sports a 8 megapixel camera with 3264×2448 pixels and with 1080p HD video capture, as well as a secondary 2 MP camera for video calling. The camera of the S3 is still hidden in a veil of mysteries and rumors, but it will probably be a 12 MP camera with 4000×3000 pixels and of course 1080p HD video capture. There will also be a front 2MP camera which is becoming quite standard.
The Battery
A lot of room for debate here as well. Those who are interested in the outcome of the Galaxy S2 VS Galaxy S3 mash-up will be particularly interested in this feature. In short the Galaxy S2 sports quite a standard battery with Li-Ion 1650 mAh. We aren’t sure about the Galaxy S3, however, it is predicted that it will come with a good-looking, slim 2250 mAh battery.
