Fans of the Xperia line and Sony's software will no doubt love the phone, with the possible exception of battery life, but those who aren't loyal to the brand may find the durable metal casing and better display on the HTC One and the myriad features and replaceable battery on the Samsung Galaxy S4 more captivating.

Reviews Word on the street for the Sony Xperia Z Ultra

That quad core S4 Pro CPU was hot stuff in the fourth quarter of 2012, but in Q2 of 2013, the world has already moved on to the Qualcomm Snapdragon 600 that's clocked a bit higher and benchmarks even faster.

The Z Ultra towers above all those phablets not only in screen size, but in specs and design, too, so if you've thrown out ergonomics and pocketability with the decision to get one anyway, you might as well do the full song and dance.

The reason the phone is so big, is because the Z Ultra sports a 6.4-inch display with a resolution of 1920 x 1080 pixels.

Where the Xperia Ultra Z made us want to cry with its camera performance, when it came to the media offerings, we were really impressed.

What People Are Saying Give it to me straight


The only caveat is that the phone slightly underexposes the frames in sunlit conditions, even in Superior Auto mode, so you might want to bump up that exposure slider a notch before taking shots outside in the bright sunlight.

The 6.4” screen is a Triluminous display with OptiContrast and X-Reality – behind all that marketing speak you see a Full HD display that is simply better than the one you'd find on the Xperia Z, for instance.
by PhoneArena (Aug, 2013)
The Xperia Z Ultra has the most beautiful display.
by TechRadar (Nov, 2013)


1080p video capture is sharp, bright and image stabilization works well.
by MobileTechReview (May, 2013)
The phone chews through every major video format you load on it, and 1080p movies look gorgeous on that 6.4” screen in their native resolution.
by PhoneArena (Aug, 2013)
This automatically makes it the world's thinnest HD smartphone, and while the bezel to the sides of the display are very narrow, there's plenty of extra emtpy space to the top and bottom, making the Xperia Z Ultra longer than we'd like.

Gmail users are automatically signed in to Google's own email app which handles Gmail with style and seamlessly integrates with mailboxes, labels and so on.

Sony's sound enhancement set is present also, with the ClearAudio+ music mode, and the Dynamic normalizer setting that evens out the volume between songs.
by PhoneArena (Aug, 2013)
It can be very agressive, but you can at least make sure that all those apps you love aren't pulling on your data connection while you're not looking at the phone.
by PocketLint (Oct, 2013)


Sure, Sony and others will say that you aren't buying this as a camera phone and most people who will want to take photos will use a dedicated camera.
by TechRadar (Nov, 2013)
The 13 megapixel rear camera with LED flash and EXMOR RS sensor takes superb photos and has HDR for both photos and 1080p video.

Close up in macro mode, the Xperia Z Ultra can distinguish text.
by TechRadar (Nov, 2013)


A heavy gaming session of Zombieland, Real Racing 3, Riptide GP2, or a hour-long run using the GPS clearly has impact on the battery life remaining.
by PocketLint (Oct, 2013)
That capacity is plenty for way above average talk times, at 14 hours cited in 3G mode, and 22 days of standby.
by PhoneArena (Aug, 2013)
The battery life is quoted by Sony as having 16 hours max talktime, 820 hours of standby, 110 hours of music and seven hours of video playback.
