Alleged leaked photos have surfaced from Chinese website EXpreview of the iPhone 5S. Although it will supposedly have the same processor, it will include an upgraded PowerVR SGX 554MP4 graphic chip. Also, included in the upgraded specs is a 12 megapixel camera, dual LED flash, 2 GB of RAM, and support for NFC and 4G LTE Advanced networks. Rumors are pointing toward a fingerprint scanner from AuthenTech, and a display featuring IGZO technology from Sharp. Previous reports have also pointed to a slightly larger battery as well. Take it all with a grain of salt until Apple officially makes the announcement, but as we've seen over the past few years, new iPhone start leaking in the summer, and they are more often than not exactly what we see Apple reveal.
