Sony unveiled the C5 Ultra along with the M5, though the C5 Ultra is slightly lower in terms of specifications. However, it makes up for what it lacks in specs with a bigger screen of 6 inches. The C5 Ultra is more of a phablet, but the specifications are not as good as the M5. The features are not equal to those of flagship devices. However, the phone reigns at the upper edge of the mid-range devices.

The C5 Ultra has a huge screen and a good camera. It is stylish and has a unique design. The battery life is good and so is the speaker.
