What we"re about to describe is the same kind of phenomenon we experienced with 5-inch phones in 2010. If you recall, that year marked the debut of the Dell Streak 5, an absolutely massive điện thoại cảm ứng thông minh / tablet hybrid for that time. Fast-forward lớn 2013, when 5-inch screens are the norm & 6.44-inch displays are now considered too unwieldy. Such is the case with the Sony Xperia Z Ultra, which borrows many traits from the smaller Xperia Z while taking on a flatter shape. Basically, Sony turned the old Z into a plate phone. As it happens, we got a chance to lớn play with one thanks khổng lồ our friends at Negri Electronics, an online retailer in the US that sells the Z Ultra"s baseline model for about $675. So is the phone comfortable to lớn hold? Does it make more sense as a tablet? & does the Ultra have any redeeming traits outside of its size?

Bạn đang xem: Đánh giá sony z ultra

I"d be using a tired cliché if I said I want khổng lồ talk about the elephant in the room, but when you compare the Z to every other điện thoại that"s crossed my desk, it seems fitting. Compared to lớn the new Motorola Droid Ultra, Sony"s Ultra definitely feels more worthy of that moniker. After all, it remains true khổng lồ the overall design and style of the Xperia Z, but there"s still no mistaking the two devices when they"re phối side by side -- or in your pocket. Yes, when it comes lớn diagonal display size, the Z Ultra is the largest điện thoại thông minh we"ve ever had the opportunity to đánh giá (unless you consider the Samsung Galaxy note 8.0 a "smartphone" since it technically is capable of making phone calls).

The Z Ultra barely edges out the 6.3-inch Galaxy Mega in terms of screen size, but when it comes lớn general dimensions and weight, there"s no question Sony"s offering is the true champion. By the ruler, Sony"s entry into the large-smartphone space comes in at 179.4 x 92.2 x 6.5 mm (7.06 x 3.63 x 0.26 inches), which makes it 11.8 millimeters taller (!), 4.2mm wider và 1.5mm thinner than the Mega. The Z Ultra is also one of the heftiest handsets we"ve played with in recent years, weighing in at 7.48 ounces (212g). Compared khổng lồ the Mega, we"re looking at a difference of 0.46 ounce (13g); given Sony"s use of finer build materials and larger dimensions, this doesn"t surprise us. Fun fact: the Z Ultra is also taller than the Kindle Paperwhite, & it weighs almost exactly the same. It"s also as wide as a standard passport; chief designer Jun Katsunuma confirmed to lớn us that this was done on purpose to lớn mimic the kích cỡ of something that travelers carry around all the time in their coat pockets.


Its kích cỡ puts it in a strange netherworld between a comfortable điện thoại and a small tablet.

But enough of the staggering numbers already -- how does the Z Ultra actually work in real life? Just as you"d expect: awkwardly. Its kích cỡ puts it in this strange netherworld between a comfortable điện thoại and a small tablet, and we have a feeling that even the largest of hands may find it a bit unwieldy. While the display takes advantage of a 16:9 aspect ratio, the bezels are quite tall on the top & bottom. This, combined with squared-off corners and flattened edges, makes for a rather unnatural fit. The Ultra"s thin frame (almost too thin, frankly) helps your fingers curl around & grasp its sides, but it still feels lượt thích a stretch; one-handed use in particular gave our mitts a great deal more exercise than we"re used to. We had no problem using the phone with two hands, although we found ourselves facing the temptation to lớn use it in landscape mode much more frequently than portrait -- in other words, the Z Ultra still feels more lượt thích a small tablet (like the Nexus 7) than a smartphone. And, much like Google"s 7-inch slate, it can technically fit in your pants pocket, but it may be too tall or wide to fit comfortably. We were constantly concerned it would slide out anytime we sat forward or changed our posture, but fortunately that never happened.

We enjoy thin phones as much as the next reviewer, but as we mentioned earlier, the Ultra may actually be a little too thin for its own good, which seems odd to say considering a thin profile is pretty much a necessity when handling a phone this size. The problem lies with the smooth, bulging edges, which make the device difficult lớn pick up off a table or some other flat surface.


Say what you will about its ergonomics, but thanks to tempered glass panels on both the front & back, the Z Ultra is one sleek device. On the downside, though, those shatterproof, scratch-resistant surfaces also make this a fingerprint magnet, & its smooth rear is hard to get a grip on. We"re happy that the designers at least kept the metallic edges raised a hair above the glass, which may be a lifesaver depending on how prone you are khổng lồ dropping phones.

In much the same way that Samsung has maintained a consistent design for its Galaxy S4-era devices (the Mega & S4 Mini are prime examples), Sony is using the same kiến thiết language it introduced with the original Xperia Z. In fact, at a glance you would think the two were close relatives, except for the fact that the Ultra clearly got a different gene for size. Both have a simple Sony logo sản phẩm just above the display with a front-facing camera lớn the left. Both have a circular aluminum power / standby button in the center of the right edge. Both feature the same build materials and squared corners. Heck, both even have holes for lanyards. Look closer, however, và you"ll find each one offers its own distinct personality.

We"ll begin with the edges, which sport small slots where the mic and speaker grille sit. There"s just one slot for each, and they sit at the top-left và the bottom-right, respectively. Both are questionable locations, since your fingers are likely to cover both slots when you use the device in landscape mode. The right is the busiest of the four sides, as it"s home to the volume rocker, power nguồn button, microSDXC / micro-SIM ports & 3.5mm tai nghe jack. You"ll find a micro-USB / MHL / USB OTG port as well as a docking port for a Sony-branded DK30 magnetic charging dock. On the front, there"s a 2-megapixel front-facing camera & an LED notification light above the 6.44-inch display, with nothing of significance below it. An earpiece resides up đứng top with a mic on the bottom, each housed in a tiny, narrow slot. Let"s not forget the back, although for the most part, it"s forgettable: the obligatory Sony & Xperia logos are here, as well as an NFC logo và simple flash-less 8MP camera. The 3,050mAh battery pack, meanwhile, is sealed underneath.

You"ll also notice that all but one of the important slots are covered with sealable tabs; the only one that isn"t is the tai nghe jack. Whereas the Xperia Z was IP57-certified khổng lồ withstand dust và up khổng lồ 30 minutes of submersion in three feet of water, the Z Ultra is IP58-certified, which means it"s technically considered "waterproof" & can survive in five feet of water for 30 minutes. This is still a rare unique in a large điện thoại thông minh sold outside of Japan, và one we"d lượt thích to see more of in our neck of the woods. It even adds khổng lồ the device"s sleek design, as the edges of the phone aren"t interrupted by very many ports. Just be careful here, because we often had difficulty snapping the tabs back into place properly.

Our đánh giá unit was the C6802 in black, with quad-band GSM / EDGE & penta-band (850 / 900 / 1700 / 1900 / 2100) HSPA+ promising up to lớn 42 Mbps down and 5.8 Mbps up. This particular model is devoid of LTE radios, so if you"re looking for the higher speeds, you"ll want to lớn seek out the C6806 (for North America) & C6833 (the European model) next month, both of which feature cat 4 with a theoretical max of 150 Mbps downlink speeds. Rounding out the specs, the Xperia Z Ultra features 16GB of internal storage (11.8 gigs of which are user-accessible), công nghệ bluetooth 4.0 with AptX và ANT+, aGPS / GLONASS support, DLNA, USB 2.0, MTP support, FM radio, WiFi Direct and dual-band 802.11a/ac/b/g/n/. Finally, you can choose from three different colors: black, white và purple.

Of course, we"d be remiss to lớn talk about the size of the phone without actually discussing the display. Before we started playing with the unit, we were concerned that Sony would approach the Z Ultra in the same way it did the Xperia Z. Despite having a much higher px density, that 5-inch TFT screen -- with its poor lighting, subpar viewing angles & unimpressive outdoor performance -- proved to lớn be one of the weakest 1080p panels we"ve reviewed thus far. Fortunately, the 6.44-inch Triluminos display is a much-needed improvement & hopefully foreshadows future flagships with smaller screens & full HD resolution.

Since this is our first encounter with a Triluminos smartphone, let"s offer a brief explanation as to lớn what the tech offers. These displays recently reappeared in Sony TVs after a lengthy absence -- the technology was dropped in 2009 due to lớn its high costs -- so it was a pleasant surprise to lớn see it show up on smaller devices so quickly. It"s an RGB LED công nghệ that employs the use of QD Display"s quantum dots -- nanoparticles that emit very specific wavelengths of light. Each dot measures between 2nm và 10nm. Rather than using a white backlight which passes through RGB filters to create the intended color, the display uses a xanh LED that stimulates quantum dots which emit pure green and pure red. In short, this new technique is supposed to create exceptionally pure colors.


The Ultra"s non-PenTile display comes has 1,920 x 1,080 resolution, which means you"ll get a pixel density of 344 ppi. This doesn"t sound very good when you compare it khổng lồ the 441 ppi density found on the Xperia Z, but we"re confident you won"t be bothered in the slightest. The Ultra"s LCD panel is much brighter & offers more natural colors than the Z (in spite of the fact that it doesn"t let you change trắng balance like the Z does). Those colors are less saturated than what we"ve seen on AMOLED panels. It also has excellent viewing angles & is one of the easiest lớn read in direct sunlight -- as long as you have it cranked up to lớn full brightness, anyway. Needless to say, we were wholly impressed by the Z Ultra"s screen; if Sony plans to lớn use the same tech for smaller smartphones going forward, we imagine it"ll give other 1080p-bearing handsets a run for their money.

Stylus fans, take lưu ý (see what we did there?): the Z Ultra doesn"t come with any special pen or capacitive stylus. (As an aside, the S Pen used on the Galaxy cảnh báo series will not work on the Z Ultra.) However, the capacitive touchscreen is coated with a "super hard coat ASF" that"s responsive và strong enough to tư vấn pen và pencil input. This, too, was included on purpose since business travelers often carry such relics with them. After hunting down a ballpoint & a trusty ol" No. 2, we can confirm that they do in fact work, though the cảm biến sensor isn"t capable of registering pressure, which means you can"t push down on the screen to get a thicker stroke.

What"s more, the slim bezels make it difficult to lớn actually write on the phone, since we naturally want khổng lồ rest the sides of our hands on the screen much lượt thích we vị when taking a pen to actual paper. As a result, we often found ourselves accidentally pressing other keys -- including the trang chủ key, sadly -- which interrupted our workflow. In ideal conditions, the handwriting-recognition software was able to accurately interpret my chicken scratch, but even then it was successful only half the time. We still prefer the good old-fashioned virtual keyboard for text input, but we imagine people can get better with time và practice. In the meantime, it makes for a decent way lớn draw pictures & do whatever else that strikes your creative fancy.



Out of the box, the Z Ultra features game android 4.2.2 Jelly Bean, although Sony has said it plans to lớn update the firmware to 4.3 at some point. The build is thick with customizations & pre-loaded software, which is true of most recent Xperia devices, frankly. You"ll be greeted by no fewer than trăng tròn apps, most of which are Sony-branded. (For what it"s worth, you can uninstall nearly half of them, while most of the rest can be disabled.) You"ll also find a couple stock features missing, lượt thích the quick-notifications panel & Photo Sphere, but Daydream & lock screen widgets are there.
