Sony Xperia Z Ultra Review

If you think that Samsung Galaxy Note III, HTC One Max, and Sony Xperia Z1 are huge, Xperia Z Ultra dwarfs them all. The latest from Sony, the phablet aims to compete with the other giants, but does it have what it takes to stand out?

Design and Build

If you’re having trouble operating the likes of the Nokia Lumia 1520, then you’re going to complain about the Z Ultra’s immense size. Because of the larger screen and fat bezels, it’s even bigger and definitely a struggle to use with one hand. Measuring 179mm long and 92mm wide, the 6.4-inch phone is just massive you might be uncomfortable holding it to your ear to place a call. Still, the size makes video watching a pleasurable experience, although you’d have to decide carefully if you want to bring a phone this huge with you all the time. On a positive note, the device is very slender, measuring only 6.5mm.


The enormous screen has full HD resolution of 1920x1080 with crisp texts and sharp icons. The screen is super sensitive, and while it does not include a stylus in the package, you can use just any pen or pencil to write or draw on it. While it’s not as precise as the Note III’s S Pen, it’s way better than using your finger.

Performance and Hardware

The Z Ultra is powered by a 2.2 GHz Qualcomm Snapdragon 800 quad-core processor, putting it on par with the Galaxy Note III. The device performed well not only on benchmarks, but also in actual usage. It is fast and responsive, and responded smoothly even while playing highly demanding games.


While the Xperia Z1 has already been able to introduce a 20.7-MP camera, the Z Ultra took a huge step down and is equipped with only an 8-MP rear cam instead. While we have witnessed outstanding 8-MP snappers, such as in the iPhone 5s, the Z Ultra fails to impress. It does produce decent quick snaps, but if photography is your passion, the Z1 is a much better alternative.

Battery Life

While Sony claims 16 hours of battery talktime, it unfortunately drains away quickly when gaming, and even in standby. As usual with most smartphones, you need to keep brightness down and turn off connectivity when not in use, but just to be safe, make sure you charge it fully before going out.

The Verdict

The Sony Xperia Z Ultra packs a wonderful display and a powerful processor in a slim, water resistant body. It’s certainly nice for watching movies and playing games, and if you don’t feel awkward bringing a phone this huge to your ears, and an immense size is important to you, then it might be worth checking out. But if you’re unsure if you’ll feel comfortable bringing this huge gadget around each time, then you might want to consider its slightly smaller predecessors or perhaps check other competitor phones within the same class.
