With the SISWOO C55, the manufacturer has created a device for users which are in need of larger screen sizes than the previous C50 while the performance has been also upgraded with a better SoC, now housing eight cores at 1.3GHz each. The camera quality does not disappoint and reaches the impressive levels of color detail which we have also seen with the C50, only that the focus may not be spot on sometimes. The battery has also suffered a small upgrade, but since we are now dealing with a more powerful SoC and a bigger screen size which both consume quite a bit of battery resources, the tests reveal a lower usage time versus the C50.
