The exterior Xperia Premium Z5 is larger, heavier, thicker Xperia Z5, but 5,5--inches Sony, as opposed to two smaller Xperia Z5 was glossy finish, not opaque. This fits well with the two selected by the designers of Sony color modifications of this phone: black and silver, but gold will begin more in keeping with matt surface smaller Xperia Z5. On the other hand, the glossy sheets very fingerprints, dust and scratches, so all the possible raptures over her appearance arrive fairly quickly;) Xperia Z 5 Premium is a gadget for those who love to feel the weight of the equipment in hand, because although 180 g is yet it is not a record in this class smartphone device a pain in the hands and pockets. Well, that weight is properly distributed and shiny, glass surface back is much less slick matte finish other Xperia Z5. Thanks to Premium Z5 not constantly slips out of your hand, and despite everything it can somehow use it. But in smartphones this size rather prefer shapes similar to the figure of Motorola Moto X Styles (particularly wedge-shaped edges of the casing and narrow frame), because xperiowy style bad Scales to such an extent and the handset does not belong to the very ergonomic and handy.

Xperia Premium Z5 inherits from its smaller prototypes all their advantages and disadvantages. Among the advantages replace good quality, discreet stereo speakers, waterproof housing without the cap with the micro-USB connector, flat key lock system with an integrated fingerprint scanner, as well as ... grip on the leash. A defect? Definitely a plastic tray at the nano-SIM card and a micro-SD card (that you can not remove a memory card without disabling the phone) and senseless location of the volume buttons. Here, it bothers even more than in smaller Xperiach Z5, as a way of keeping such a large smartphone is changing more difficult and less pleasant. We hope that in the future generation of Xperia Z manufacturer do something about it. Description Xperia Premium Z5 began by saying that it is larger, heavier, thicker Xperia Z5, and so it will end, because it is difficult to write something insightful. It is a properly designed and well-made phablet, after which you can actually see that it is a first-class equipment, but if you counted on for a breath of fresh air, and any innovation, know that you've come to the wrong article. Xperia Z5 Premium is just - and until - the essence squeezed out of the last actions of Sony in the market of smartphones and the essence of this one responds, Let's get to the most important questions related to the Xperia Z 5 Premium: is whether the screen resolution on your smartphone makes sense.

Resolution 3840 × 2160 and 5.5-inch diagonal give density at 806 pixels per inch, while the 5.5-inch screen G4 LG QHD amounts to 538 ppi, and devices with full HD - 401 ppi. Even when testing the LG G3, which is the first commercially available phone to display QHD, we mentioned that the difference between Full HD and Quad HD hard to see, so it's easy to guess that watch to advantage between the Quad HD and Ultra HD is even harder. But is it impossible? No, but can be held only in specific situations or in pictures with a lot of very small, closely spaced parts, particularly when an image is displayed with a high number of thick and parallel or nearly parallel line. And of course the most important condition is to look at the screen from a distance of a few centimeters. So in the normal course of typical viewing photos and videos advantage Xperia smartphones Z5 premium over not endowed with so many pixels, is highly theoretical. The more that the Xperia Z5 Premium renders the image at a resolution of UHD only when displaying photos and videos, and the interface, games and all other programs are rendered in full HD - mainly just to save energy and relieve layout, which simply would not offer satisfactory liquidity image in any situation in resolution of UHD.

But it is not all related to the Screen hooks Xperia Z5 Ultra. Next, it is noted when it falls on a little more light. Then it turns out that Sony still does not know where you're ordering good digitizers: Yet another is associated with a poor color reproduction. They are very intense, a little less than Samsung's AMOLED-ah, but white is frighteningly blue and the gamma curve reveals a strong exaggerate colors. The result may please some, but next time please some sensible color profiles in smartphones of the brand.During testing we noticed, too, that when you turn on the screen for the first 2-3 seconds. the image looks strange and is devoid of contrast, if the system needed a moment to load the correct profile of the color.In summary, Sony Xperia Z5 Premium installed the most advanced presently LCD screen. It has a space resolution, great images of black, it is very clear (as in the case so dense packing of pixels is no small achievement), and - thanks to technology Triluminos - is able to show very intense color. However, its potential to inhibit both certain - typical for smartphones Sony - shortcomings and technical constraints as well as ... the possibility of human eyes and brain. Ultimately, this screen tests ended with slightly mixed feelings, because in many ways delights, but also in many slightly disappointing and makes seriously consider whether the pursuit of pixels makes any sense and whether it would be better to first take care of the fine tuning basics .. . Having said that, we thought the Xperia results in tests Z5 Premium operating time will be disastrous. Firstly, because the longer the performance of Xperia Z5 did not fill us particularly optimistic, and secondly because the screen resolution must consume a lot of energy. It turned out, however, that the Z5 Premium is doing in this regard much better than expected, although to a large extent it depends on how you use your smartphone. During typical use getting an approximately 4.5-5 hours with the screen on, which is a good result. We did not notice any onerous or wakelocków, so uptime at rest is also good.

The problems begin when the user wishes to use the maximum brightness of the display or take full advantage of the resolution, because the recording and playback of UHD here is very costly energetically. Here is an example. Discharge cells of the smartphone continuous playback of Full HD video takes 6-7 hours (depending on the set the backlight brightness), and continuous movie playback Ultra HD - 4-4.5 hours. The noticeable difference, right?The remainder still to discuss the issue of charging. Xperia Z5 Premium supports QuickCharge 2.0 technology, so when you connect the dedicated charger its cells can be filled from zero to 100% in about 1.5 hours, but ... in the kit is accompanied by mere 1.5 amp charger that does it in less than 3 hours All Xperia Z5 are very similar to each other in terms of components and software, so instead of a full description of multimedia features, camera, and other elements of this smartphone, which were already in the Articles of models Z5 and Z5 Compact, here we put a few loose perceptions. Traditionally, the strength of the Xperia is a multimedia support.
