Sony Mobile last year gave us a deep impression. I can't forget its half kilogram fitness equipment Sony XZ2 Premium. The barbell costs are saved. Every time you take it out to play is an opportunity to exercise.
This year's Sony is a little different, Xperia 1， The biggest highlight of Sony Mobile's flagship mobile phone this year is that it is no longer as heavy as half a kilogram. The biggest highlight is that the body is equipped with a 4K 21:9 OLED screen. Previously, Sony mobile phones have been equipped with a 4K screen as standard, but all of them use LCD materials. This time, Xperia 1 uses Samsung's 4K OLED panel, which should be the first mobile phone equipped with a 4K OLED.
screen
Let's take a look at the detailed parameters of this screen. The resolution is 3840 × 1664, and the screen scale is 21:9. It supports HDR content display. The panel supplier is Samsung.
Other manufacturers use the 16:9 ratio of native 2K resolution to lengthen the vertical resolution to 2K level resolution. For example, Samsung and OnePlus use 2560 x 1440 at 16:9 to 3120 x 1440 at 19.5:9.
Sony's approach is more like compressing the 4K horizontal resolution at 16:9 to 21:9, which is well proved by the previous generation of XZ2 Premium, The resolution of Xperia 1 is 3840 × 1664, while the resolution of XZ2 Premium is 3840 × 2160. Obviously, the horizontal resolution is reduced while the vertical resolution is unchanged, resulting in the total number of pixels of Xperia 1 being only 77% of that of XZ2 Premium.
This does not mean that Sony is making false propaganda, because the definition of 4K is that the number of pixels on either side of the screen reaches or approaches 4000 pixels, and the number of vertical pixels of Xperia 1 is 3840, which is undoubtedly close to 4K.
The system integrates two optional color modes: master mode and standard mode. The default option is standard mode.
By convention, we tested the objective data of the screen.
Manual maximum brightness is 380nit, full white excitation brightness is 642nit, and local excitation brightness is 800nit.
In the standard mode, the sRGB gamut covers 133.5%, while the P3 gamut covers 98.4%. Gamma and gray scale data are also good. The first impression of the screen is quite good, and it's comfortable to see.
In master mode, The sRGB color gamut covers 95.4%, the average color deviation is 1.9, and the maximum color deviation is 4, which is very excellent. There is also a 10bit color depth. Although this 10bit color depth is achieved through 8bit pixel jitter, the hard quality of the screen is good.
In addition, the Xperia 1 screen also supports the BT.2020 color gamut. BT.2020 is the color standard for the next generation of UHD video production and display system issued by the radio communication department of the International Telecommunication Union. The BT.2020 standard defines that the display resolution of UHD images is 3840 × 2160 (4K) and 7680 × 4320 (8K), and the image display ratio is 16:9, and progressive scanning is used.
Compared with BT.709, the BT.2020 standard has greatly improved the performance specification of video signals. The color depth has been increased from 8bit to 10bit or 12bit in the BT.709 standard. The area covered by the color gamut is also much larger than that in the BT.709 standard, which can display more rich colors.
The above figure shows the area occupied by BT.2020 and BT.709 in CIE 1931 chromaticity diagram respectively. It can be seen that BT.2020 is much larger than BT.709, which means that BT.2020 can display more colors than BT.709.
BT.2020 Color gamut is widely used in professional fields, such as professional displays, professional cameras, and film industries. The 4K HDR video uses the BT.2020 color gamut.
The above description of BT.2020 may be difficult to understand. In short, BT.2020 is a higher specification color range and the next generation color gamut standard.
The Xperia 1 screen on our hand covers 49.4% of the BT.2020 color gamut.
Let's talk about the daily use of this 4K screen:
Daily browsing text The experience is higher than 1080P A screen, and the words are more sharp. More importantly, the content displayed vertically on the screen is more than the current mainstream 19.5:9 full screen mobile phones. It is the first time to see the hairtail screen with this ratio on the mobile phone, and the browsing effect is quite good.
Video viewing Thanks to this 4K OLED HDD screen, it is very enjoyable to watch some 21:9 movies. Movies occupy the whole screen of the phone, without wasting any part of the screen. It is really a pleasure.
However, the above scenes are rarely encountered in daily use. At present, except for some movies that use the ratio of 21:9, most of the other videos still maintain the ratio of 16:9. At this time, it will be counterproductive to watch videos on this screen. The black edges on the left and right sides of the horizontal screen are particularly wide, wasting a lot of screen space. Actually, the domestic online video software Tencent and iQI can't turn on 4K resolution and HDR, so if you want to see high-quality movie sources, you can only use scientific Internet or Internet to find resources.
Game experience Thanks to the strong compatibility of Android system, currently popular games can basically run at a ratio of 21:9. But there will still be one or two games that don't fit. It doesn't have much effect on people like me who play with little hands.
It should be noted that Xperia 1 does not render at the screen's native resolution, but at 2560 × 1096 resolution.
This leads to the fact that the actual sharpness is not even as good as the 2K screen rendered with native resolution. Take One Plus 7 Pro for comparison. Two mobile phones open the same web page and take a screenshot. Then put the screenshot on the computer to compare.
It can be seen that the right OnePlus is clearly clearer than Sony. Both the edge of the text and the pictures in the screenshot are slightly better than OnePlus. The font of Xperia 1 seems a bit blurry. Of course, the physical resolution of the mobile phone is up to 4K, so it will not be as obvious as the enlarged screenshots on the mobile phone, so it is naturally higher than those 1080P A screens.
When will Sony Xperia 1 use native 4K resolution to render?
The author tried most of the applications on mobile phones and found that only when photo albums and 4K videos are played, the original resolution of the screen will be fully used for rendering. Usually, browsing the web, watching videos, and playing games are rendered in 2560 × 1096 resolution. This must be a compromise for Xperia 1's endurance.
appearance
This Xperia 1 adopts the design of glass and metal middle frame at the front and back. The front 6.5 inch screen is free of water drops and bangs.
However, the width of the forehead and chin is not the same. The forehead is slightly wider than the chin. It's better when not found. When I know this cruel truth, I will involuntarily pay attention to the forehead and chin. The forehead is integrated with a notification light, a light sensor, a front camera and a receiver. The receiver and the bottom speaker form a stereo speaker, which supports Dolby sound effect.
There are many slots in the middle box. The first is the allocation of keys. All the keys of Xperia 1 are placed on the right side of the fuselage. This generation has returned to the side fingerprint identification. The fingerprint identification key and the power key are designed separately. And Sony's ancestral shutter button.
Therefore, there is a strong contrast between the left and right sides of the middle box. On one side, there are no buttons, and on the other side, there are uneven buttons. The area of the power key is relatively small, which increases the difficulty of blind operation.
The experience of fingerprint identification is also ordinary, the unlocking speed is ordinary, the success rate is not high, and the experience is too unfriendly for students who are used to playing with mobile phones with their left hand.
There is a SIM card slot on the top of the middle frame. The SIM card slot can be taken out without a card taking pin. There is a waterproof rubber ring. The card slot is designed as 2 out of 3, which can expand the TF card. It makes up for the fact that the body has only 128GB of storage.
However, Sony always gives me a chance to say that this generation still does not support hot plug. When you pull out the card slot, you can see the familiar words "restarting".
The back is designed with glass. The Xperia 1 has four colors in total: dark at night, fog grey, snow white, and magenta. The texture of these four colors is good, and they are all very beautiful. My favorite is purple. Unfortunately, we were out of stock when we bought it, so we had to return it and buy foggy grey.
The most conspicuous thing on the back is the camera design. The cameras are arranged vertically and the modules are prominent. From top to bottom: main camera, telephoto, ultra wide angle. There is also an NFC tag on the left of the camera module. Sony's logo is placed in the middle. This logo is the value of this phone. The Xperia 1 body supports dustproof and waterproof IP68 and IP65 certification, which is the standard configuration of Sony mobile phones.
In general, Sony Xperia 1 has a good texture and is worthy of SONY's LOGO. The whole machine is exquisite, revealing a high-end flavor. Its weight has also been successfully reduced to less than 190g, and its appearance is more in line with the author's aesthetic. But there are some small details that are not so good.
camera
Sony Xperia 1 is equipped with a popular three camera combination, a combination of standard wide-angle, ultra wide-angle and telephoto lenses, which has become a flagship standard configuration this year.
The three camera parameters of Xperia 1 are as follows:
Main camera: IMX4451200W pixels, 1/2.6 "sensor size, 1.4 μ m unit pixel size, f/1.6 large aperture, OIS optical anti shake support.
Long focus: S5K3M31200W pixels, 1/3.4 "sensor size, 1 μ m unit pixel size, f/2.4 aperture, OIS optical anti shake support.
Ultra wide angle: S5K3M31200W pixels, 1/3.4 "sensor size, 1 μ m unit pixel size, f/2.4 aperture.
To evaluate Sony's CMOS combination, the main camera uses the IMX445 provided internally, while the telephoto and wide-angle use Samsung's S5K3M3. It is rare to use the S5K3M3 on ultra wide-angle. It is said that the CMOS packaging screen will be sold more cheaply, so there are two S5K3M3.
The parameters of the surface hardware are relatively close to last year's IMX363. In fact, the hardware is much higher than this year's IMX586. The IMX445 uses three-layer dbi technology, Gen6 architecture (IMX586 is Gen2), built-in DRAM chips, and 960fps super slow motion video mode has also been enhanced.
But Sony always uses the best hardware and gets the worst results. Let's take a look at the sample:
First, let's take a look at a group of backlight scenes. The sky of Xperia 1 is heavily exposed, and there is a ghost in the branches. The dark green is also restored to light green, and the restoration is relatively correct.
The exposure of Xperia 1 is still high, and the picture is white, while the exposure is low, and the real scene is between two mobile phones.
Another picture of a cloudy science park. The picture of Xperia 1 seems to brighten the dark part and shadow in the later stage, so the overall picture is a bit "gray", with low saturation and contrast, which has a cinematic feel.
This Xperia 1 is the same as the previous one. It brightens the dark part and reduces the contrast and saturation.
Zoom in to see the details. It is found that the purity of the Xperia 1 picture is poor, and the noise and smear marks are obvious.
Summarize that Xperia 1's daytime picture exposure is high, sometimes white and gray, HDR effect is good and bad, and the picture purity is poor.
Nightscape
At night, the performance of Xperia 1 is completely opposite to that of daytime. At this time, the brightness contrast plus 7 Pro is no longer dominant, and the exposure of dark shadows is relatively low.
The high light of Xperia 1 is over exposed, the dark part is under exposed, the light box and the image look are obviously inferior to that of one plus 7 Pro.
Zoom in to see that the highlights have become a mess, and the color details are seriously lost.
Most importantly, the anti glare ability is really poor. Here, Xperia 1 seems to have photographed the whole universe. It greatly affects the appearance of photos.
If the light is not very complicated, the imaging quality of Xperia 1 is still acceptable, at least in terms of analytical power, there is no significant difference with One Plus 7 Pro.
long-focus
The telephoto lens of Xperia 1 is 2x zoom, and the following tests are double zoom of two mobile phones.
It can be seen that the analytical power of Xperia 1 using the telephoto lens is better than that of one plus 7 Pro using the main camera digital cutting.
Super wide-angle
Ultra wide angle continues the main shooting algorithm, giving priority to dark details, and the sky is overexposed.
Photo experience
Xperia 1 has an independent shutter button. When the screen is stopped, long press the shutter button to activate the camera. In the camera, half press the shutter to focus, and press it to take a picture.
Sony has a lot of photo experience slots. The first is:
The viewfinder resolution is low. For several times, I thought it was out of focus. It is reasonable to say that the 4K resolution screen would be clearer, while the viewfinder of Xperia 1 would be blurry.
It is easy to lose focus at close range. When taking a picture near an object, the phone sometimes focuses to the side, and you need to manually click the screen to focus.
The background synthesis takes a long time. After pressing the shutter, the photos will be processed in the background. At this time, you can't see the whole picture. You need to wait for a moment.
To sum up, Sony Xperia 1 still has a big gap between its camera comprehensive strength and the current domestic camp. The experience is also the same as that of Sony's micro single camera, which is one iPhone away from the word "easy to use". But after all, this is Sony, and we are used to it. We don't have much expectation for the photo quality and experience of Sony mobile phones.
Battery life charging
Now that the endurance is mentioned above, let's test the endurance performance of Xperia 1.
Xperia 1 is equipped with 3330 mAh battery as standard. For a mobile phone with 4K OLED screen, Sony only equipped it with more than 3000 mAh battery. Sony Heart is really big.
after Love to play computer games In the two-hour endurance test, the remaining power of Xperia 1 is 79%. Sure enough, the endurance is worse than that of Xiaomi 9 with similar battery capacity. It is also expected to use the 4K screen and 3330mAh battery range, but I don't know why Sony doesn't equip the Xperia 1 with a larger battery. The flagship mobile phones released this year have been continuously powered by 4000mAh batteries, including Samsung, an international manufacturer. Sony is still independent. No matter how your industry progresses, Sony is still standing still.
Sony Xperia 1 is equipped with standard C to C data cable and PD charging head. The data cable is close to Google, an international manufacturer. If you need to connect a PC to transmit data, you may need to buy an A to C data cable. In addition, the Type-C port of Sony Xperia 1 supports the USB3.1 Gen1 standard, which is much faster than the conventional USB2.0 in the wired transmission speed.
The charging head supports PD protocol and PPS QC4+fast charging protocol. Using ammeter to induce protocol test, there are 4 constant voltage gears and 2 PPS gears, with the maximum power of 18W.
What's more interesting about the standard charging head of Sony Xperia 1 is that the standard charger rarely has a PD charging head that provides a constant voltage gear of 7V, and this charging head supports the PPS protocol. In fact, the maximum charging power of a very good looking charging head is only 18W, and it is not possible to charge those 27W charge pump fast charging mobile phones, which is a bit chicken ribs.
The original charging head is used for charging, the maximum power is about 15W, and the PD protocol 7V/2.57A gear is used for handshaking. The power change during charging is shown in the figure above.
The peak power of Xperia 1 remains about 15W 40 minutes before charging, and then drops to about 8W. After charging for an hour, the power drops to about 5W. Charging starts from 0%, 47% in half an hour, 81% in one hour, and it takes 1 hour and 40 minutes to fully charge. For a battery with only 3330mAh, it is not fast, or even slow.
The author also uses other PD charging heads for charging test. At this time, Xperia 1 will give priority to the PD gear of 9V/2A.
Measured with a third-party PD charging head, the maximum charging power is about 15W, which is almost the same as the original charging head.
According to the actual measurement, 0% starts charging, 45% charges in half an hour, 79% charges in one hour, and it takes 1 hour and 45 minutes to fully charge, which is no different from the official charging head in terms of charging duration.
In addition, the author also tested the charging compatibility of Xperia 1, and found that Xperia 1 does not support fast charging protocols other than PD. That is, if you want to fast charge Xperia 1, you can only use the C to C data cable and the PD charging head to achieve a maximum of 15W fast charging.
System experience&use experience
Sony's Xperia 1 system is not easy to use. It is also a platitude. The Xperia 1 system is based on Android native, so many native features have been completely preserved.
The use experience is also very close to the native Android, which means that this mobile phone does not have any localization services, such as yellow pages, automatic blocking, duplicate verification code, cloud backup service, and bus card. WeChat and Alipay cannot use fingerprint payment.
When using the telecom 4G card for Xperia 1, please note that you can only use data to access the Internet and make calls if VoLTE is supported. If your region does not support VoLTE or your telecom operator cannot open VoLTE, it means that your Xperia 1 mobile phone will not be able to access the Internet and make calls. China Mobile and China Unicom certainly have no such restrictions.
After disassembly, it was determined that the vibration motor was a transverse linear motor. However, this vibration did not make me feel that it was a normal experience for a transverse linear motor. On the contrary, it was inferior to some longitudinal linear motors. It is estimated that only Sony has the strength to optimize the transverse linear motor.
Moreover, the system is already so difficult to use, and the official system update frequency is also slow. This mobile phone has been upgraded twice since it was bought back in June to the deadline (7.12). One update was updated when it was just bought out of the box, and the upgrade log did not clearly write what was updated. Sony feels good about its own system?
summary
Sony Xperia 1 is a mobile phone with very distinctive features. The sleek R angle, narrower border, wireless charging, fingerprint under the screen and other popular elements of modern smart phones are all absent.
In contrast, it has black technology that other mobile phones do not have, such as the 21:9 4K OLED screen, X1 for mobile image processing chip, the recording function of "movie master", and the display technology of BRAVIA black technology.
So is Sony Xperia 1 a phone worth recommending? Obviously not. The high price of ￥ 6299 is enough to buy all mainstream mobile phones except the iPhone XS Max, and Xperia 1 is not superior to them.
So this phone is recommended to the following people:
