The Xperia series has changed its name again, from the previous XZ to the digital series, but it is not as simple as launching a new flagship under a different name, and the Xperia 1 means that the One Sony concept is finally embodied in Sony's mobile division. The display is powered by a BRAVIA X1 mobile processing engine, the triple camera system is powered by Sony's Alpha Binoz X mobile image processor, the sound effects are in collaboration with Sony Picture Entertainment, and the CineAlta team is also involved in the tuning of the video shooting function. It can be said that since the Xperia 1, Sony Mobile has really received the support of other advantageous departments of Sony, regardless of whether the support is large or small.
 
In terms of exterior design, Sony's early OmniBalance design language on the Z series caught the attention of consumers, while the XZ series adopted the Ambient Flow design language, although it was not loved by consumers, but it still had an excellent grip. When it comes to the Xperia 1, Sony seems to have found a balance between the two languages, with the boxy shape of the OmniBlance, and at the same time, the edges on both sides have a 2.5D arc, and the grip is also comfortable with Ambient Flow.
 
Because the Xperia 1 uses a rare 21:9 with a fish screen in the industry, the body length reaches 167mm, which is currently the longest flagship phone. The width is relatively restrained, only 72mm, which is relatively easy to hold, but for the sake of feel, the inside of the fuselage can only continue to reduce the size of the battery, which has advantages and disadvantages.
 
Sony on the XZ3 is inspired by the four seasons, and the Xperia 1 also uses 4 colors, but this time it did not work on the color change like other flagships, but returned to black, white and gray and unique purple, of which black and gray are more business-like, the texture of white is amazing, and purple is very pleasing to the eye due to its unique hue of blue and purple and not purple.
 
Xperia 1Behind is a vertically arranged triple camera combination,Left and right symmetry,This design is also very rare in flagship models,In the past, Meizu pursued symmetry in design,But in 16s, because of the internal structure of the fuselage, the vertical middle camera module was abandoned,From this point, it can also be seen that Sony still has its own uncompromising side,It's just that this design will squeeze the vertical space inside the phone,The battery size will also be affected。
 
The buttons are concentrated on the right side, and Sony's side fingerprint has also returned, but it's not a good thing, it is placed separately from the lock screen key, making the elements of the right side of the bezel a little complicated, and the unlocking speed is slow compared to Goodix's latest under-screen fingerprint solution, and the early models will occasionally have the bug that fingerprint recognition cannot be recognized, so we can only wait for the update to solve. There is also a two-stage shutter button on the lower right side, which allows you to press to focus and repress to shoot, much like the shutter button on a camera. There are speakers on the top and bottom, Dolby Atmos support, there is no headphone jack, but there are Hi-Res and Hi-Res Wireless certifications, and LDAC is also supported.
 
The "dynamic vibration system" on the XZ series is also inherited from the Xperia 1, when watching movies, listening to music, and playing games, the phone will vibrate accordingly with the picture and sound on the screen, but in daily use, the vibration of this horizontal linear motor is relatively average, and even a bit like a rotor motor, and the tuning is not very good.
 
The screen is a big selling point of the Xperia 1, as it is the world's first 21:9, 4K, HDR, OLED screen, provided by Samsung. The physical resolution of this screen is 3840×1644,643PPI, even if converted to a standard RGB arrangement, it is still very delicate. At the very beginning, this screen caused a debate about real and fake4K, but in fact this is a question of standard applicability. In TV and consumer media, 3840×2160 (4K UHD) is the dominant 4K standard, while the cinema projection industry uses 4096×2160 (DCI 4K), and 3840×1620 is compliant with the 4K UHDTV standard according to the SMPTE (Society of Motion Picture and Television Engineers) HUDTV1 standard. In addition, the Xperia 1 screen has also passed the SID (International Society for Information Display) 4K certification, so the Xperia 1 is indeed a 4K screen, and there is no dispute.
 
What is the significance of 4K mobile phone screen? According to DisplayMate's long-standing point of view, due to the sub-pixel rendering technology, and the small screen size of the mobile phone, so the significance of 4K resolution in the field of mobile phones is actually not great, like Apple XS Max and Samsung S10+ models with a long side of more than 3k, compared with Xperia 1, unless the details are very large, it is difficult to detect the difference with the naked eye in daily use. 4K mobile phone screen is more in the form of a long board, mainly because no one has me, people have my excellent selling point, Xperia 1 can also be said to be the best in the current smartphone.
 
Xperia 1 also can't stay at 4K resolution for a long time, after testing, it will only turn on 4K resolution when needed, such as opening an album or playing 4K video, if you forcibly lock the 4K resolution, it will cause a large area of touch failure, in addition, turning on 4K resolution for a long time will also lead to a significant reduction in battery life.
 
21:9This ratio plus a complete screen,No water drops、No notch、It's not a curved screen,It does have a very good immersive experience when watching movies,But this also means that when it watches mainstream 16:9 video,There will be black edges on both sides,When you pull to the full screen,Part of the content will be missing up and down,This is the disadvantage of the screen using niche proportions。 The Xperia 1's ability to show two programs at the same time is also a highlight, but its limitation is that there are not enough apps that support the split-screen feature.
 
The Xperia 1 supports 100% of the DCI-P3 color gamut, compared to 88% for the Samsung S10+. It also supports the ITU-R BT2020 color gamut, which covers 75.8% in the CIE 1931 color space, 53.6% in DCI-P3, and 52.1% in Adobe RGB. This screen also supports 10bit tone level,It is also the top level in the field of mobile phones,It can make the color transition smoother,But this 10bit is not native 10bit,But through 8bit jitter becomes 10bit。 On the display, it is also a routine operation for 6bit to become 8bit by jitter, but the color transition will inevitably become disordered, and the native 8bit color transition on the small screen of the mobile phone is already very smooth, even if the jitter is 10bit, the naked eye can not see the difference, which is also the presentation of BRAVIA technology.
 
There is not much to introduce in terms of performance, it is still the current flagship SoC Snapdragon 855, and the running score is also in line with normal performance, but there is only 6GB as an option in terms of memory, according to the current mainstream flagship machine, 6GB can also meet the use, but consumers with a longer replacement cycle, there is still a lot better with the 8GB version.
 
When it comes to taking pictures, the previous mobile phones may not have reflected the quality that Sony should have, but this time with the participation of the Alpha department, the Xperia 1's photo performance directly entered the first echelon. In terms of hardware, the Xperia 1 only has the IMX 445 for the main camera from Sony, and the rest of the wide-angle and telephoto are Samsung's S5K3M3, and all three cameras are 12 million pixels. The front camera, also from Samsung, is an 8-megapixel S5K4H7.
 
Although the three cameras come from different manufacturers,But the adjustment of the cable shift is very good,Switch different lenses,The style of the finished film is very consistent,There will be no obvious differences,It's just that the application of this photo doesn't seem to be high,The process of switching is relatively slow,You always need to wait for a while。 The main camera is very good during the day, with an overall style bias towards natural realism, moderate saturation, accurate white balance without forced sharpening, excellent detail preservation, and Auto HDR only turns on when it's absolutely necessary, with improved highlight reduction and shadow detail preservation.
 
The Xperia 1 uses eye tracking when shooting portraits, which is a very good focus advantage, with very natural portraits in motion and excellent background blur. Compared to the Pixel 3, the contrast ratio is a little lower, and it looks more pleasing to the eye.
 
In the night scene, the Xperia 1 also tends to be more natural, trying to preserve dark details and suppress highlights while ensuring chiaroscuro, which seems to be a good sign for the mobile phone industry. However, it is important to note that when a portrait appears in a night scene, the camera will actively focus on the face, which will affect the brightness of the background, in which case it is best to turn on the manual mode to switch the metering method.
 
Xperia 1The video recording is also worth mentioning, although most consumers may only use the normal mode, but the Xperia 1 has added the Cinema Pro mode, the whole interface looks very professional, different cameras have a very uniform imaging style, and there will be no color changes back and forth during post-editing. The playability of this mode is very high, but unfortunately Sony does not have its own editing software, and you need to download it separately or do post-production on PC. For the average consumer, Steady Shot and 960fps slow motion may be more likely to be used. When shooting video with Steady Shot, the Xperia 1 is less prone to blur than the iPhone XS Max. Slow-motion shooting is Sony's long-standing strength, as it's a real slow-motion shot, not a PPT slow-motion with interstitial frames, but it does require a lot of light to shoot usable video.
 
The system is Sony's shortcoming,Its localization is not as good as other domestic manufacturers,And also based on Android9,Sony's system is also more prone to bugs,Even if it's the main Side Sense function,It's not accurate every time,The user experience is worse。
 
In terms of charging range,Xperia 1Support PD fast charging,The peak power can be maintained at about 15W,It's not slow for a battery with only 3300mAh,It's just that Xperia 1With this battery capacity4K screen,Power consumption is really amazing,Even if you turn on power-saving energy,You can only barely cope with light use,If you use it moderately,It's normal to charge twice a day,After all, no matter how you optimize power use,Battery capacity is still limited。
