2020 marks Xiaomi's 10th anniversary, and the Xiaomi Mi 10 Ultra debuted as the first flagship device in the second half of the year. Compared with Xiaomi Mi 10 and Xiaomi Mi 10 Pro, Xiaomi Mi 10 Ultra has done a very good job in terms of appearance recognition, the reason is that it places four high-spec cameras in a vertical row, resulting in a very huge rear camera module, which is really not good-looking, but it is really easy to recognize.
In addition to the rear camera module, the process and color matching are also the direction of the Xiaomi Mi 10 Ultra's efforts, and the three colors are ceramic black, bright silver and transparent, all of which are the directions that Xiaomi has explored in CMF. The three colors are very good, the most difficult process is bright silver, the most distinctive style is the transparent version, in contrast, ceramic black really has no characteristics.
Ceramic black pays tribute to the MIX ceramic version, although it is called ceramic black, but it is actually sprayed with 200nm ceramic coating on the surface of the glass back cover, which feels and looks very similar to ceramic. If it is completely made of ceramic, the original 224g body weight will have to be added, which is difficult to accept for daily use, this scheme has a gap with Meizu 17 Pro's ceramic white, but it balances texture and weight, which is a compromise option.
The transparent version is blackened around the glass to cover the viscose, and because the internal components are mainly black, the transparent version also looks black. Unlike the transparent exploration version of the Xiaomi Mi 8, the transparent version of the Xiaomi Mi 10 Ultra does not make a pattern on the back cover of the glass, but really uses a piece of transparent glass, which is very geeky.
The Bright Silver version appeared on the Xiaomi Mi 6, which was not officially commercially available at the time, and now it is finally a wish. This bright silver is electroplating coloring,In the year of Xiaomi Mi6,The yield rate is only 6%,After process iteration,Now it can finally be mass-produced,But the yield rate is still not high,It is also the lowest output of the three colors。 None of these three colors are easy to care for, but unlike the AG matte process, they are very susceptible to fingerprints and need to be wiped frequently.
In terms of other configurations, Xiaomi Mi 10 Ultra is still equipped with stereo dual speakers, but the top is changed to an earpiece speaker, and the external sound quality has maintained a relatively high level, but after all, the specifications have shrunk, which is not as good as Xiaomi Mi 10 Pro. This is mainly because the rear camera module occupies too much internal space, and even the double-layer motherboard is designed as a special-shaped with nine curves and thirteen bends, and there is no place to put symmetrical speakers.
Xiaomi Mi 10 Ultra has replaced the screen, Xiaomi Mi 10 Pro was an OLED screen supplied by Samsung in the early stage, and now there is Huaxing Optoelectronics as a secondary supply, and 10 Ultra is directly supplied by Huaxing Optoelectronics. The refresh rate of this screen is 120Hz, and the touch sampling rate is 240Hz (180Hz for daily and 240Hz for gaming), which is an improvement over the 10 Pro's 90Hz 180Hz. The color depth has also been upgraded from 8bit to native 10bit, the color transition is smoother, the previous model with 10bit color depth as a selling point is Sony Xperia 1, but that is to use 8bit jitter to10bit, Huaxing Optoelectronics is the industry's first native 10bit screen.
Screen brightness is the advantage of SamsungE3 screen,Xiaomi Mi 10 UltraAfter replacing the OLED screen of Huaxing Optoelectronics,It can also have similar performance in this regard,Manual maximum brightness450nits,Full screen excitation brightness reaches about 790nits,And the official 800nits belong to the error range,The peak brightness is up to 1120nits,supportHDR10 Image display。
Color accuracy has always been the advantage of Xiaomi's digital series, and there are independent color grading before leaving the factory, which belongs to the first echelon in flagship models. The official DeltaE is less than 1, and the JNCD is less than 0.63, and in the actual measurement, the primary color mode can reach this number, the Delta E of sRGB is 0.9, and the adaptive mode and vivid mode are both P3 color gamut, and the average Delta E is greater than 3.
Huaxing Optoelectronics' panel adopts the Pearl sub-pixel arrangement, which is similar to the Samsung Pentile arrangement, the blue sub-pixel and the red sub-pixel are four-pointed stars, and the green sub-pixel is oval, and the discount rate is similar to that of the Samsung diamond row. From the front, there is no obvious difference between the look and feel of Huaxing Optoelectronics and Samsung, but the angle is a little off, and you can see that the 10 Ultra screen is yellow-green, and the viewing angle is not as good as Samsung.
In addition, it should be noted that the DC dimming and 120Hz refresh rate in the early stage of the Xiaomi Mi 10 Ultra cannot be turned on at the same time, and the refresh rate will be limited to 60Hz when using DC dimming, which is expected to be solved by OTA upgrade in the later stage. In general, from Samsung to Huaxing Optoelectronics, the screen quality of Xiaomi Mi 10 Ultra is still upgraded more, and the yellow-green color at low angles is also flawed, if there is a 2K resolution, then there is nothing to regret.
In terms of performance, the Xiaomi Mi 10 Ultra still uses the Snapdragon 865 SoC, comes standard with LPDDR5 memory, and the flash memory is upgraded from UFS 3.0 to UFS 3.1. Qualcomm's sales of the Snapdragon 865 have limited the manufacturer's region, Lenovo and ROG have bypassed this restriction to get the supply, and other domestic Android manufacturers have optimized the 865 tuning to achieve the same or even better performance as Qualcomm's official one. Among gaming phones, the Black Shark 3S is even better optimized than ROG, and you don't need to go too far with the 865.
The maximum frequency of the GPU of the Xiaomi Mi 10 Ultra is set at 725MHz, which is one notch higher than the 670MHz officially overclocked by Qualcomm, but only some games on the whitelist can run to the highest frequency, such as the Bright Mountains, and can only last for about 5 minutes, and more often work at 670MHz.
The heating performance is also very good,Peace Elite has the highest image quality60Frames,The maximum body temperature in half an hour43 degrees,This performance is very good even if it is compared with a game phone。
The image part is a very big improvement in the Xiaomi Mi 10 Ultra, first of all, the hardware part is very full. Main camera, 2x portrait, periscope telephoto, and ultra-wide angle are all available. The main camera uses a new CMOS, which is OmniVision's OV48C, with 48 million pixels with optical image stabilization; The double telephoto is the Samsung S5K2L7, with 12 million pixels; The periscope telephoto is a 5x optical change, and the CMOS uses the flagship main camera IMX586 from 2019, with OIS, and the specifications are really high; The ultra-wide angle is the IMX350, and the hardware is nothing special, but there is a night mode.
The main camera has two special technologies, namely dual native ISO Fusion and single-frame progressive HDR, and the Sony IMX689 also has a similar dual native ISO, but there is only one analog-to-digital converter, which can only choose between low gain and high gain, while the OV48C has two analog-to-digital converters, which fuse the two native images of high ISO and low ISO after digital gain, so as to obtain a high dynamic range photo.
Single-frame progressive HDR and multi-frame synthetic HDR principle is not the same, single-frame progressive HDR as the name suggests is in a frame, line by line output three exposure signals, such imaging speed is indeed faster, and can avoid the situation of ghost in multi-frame synthesis HDR when shooting moving objects, however, the requirements for camera stability will be higher than multi-frame synthesis, even if there is OIS optical image stabilization, a little shake when pressing the shutter, it is easier to paste. Roughly speaking, single-frame HDR has higher requirements for handheld stability, and multi-frame HDR has higher requirements for the stability of the shooting object.
In the actual imaging part,OV48C's performance is stronger than Xiaomi Mi 10 ProIt is expected,Although the resolution is weaker than 100 million pixels,But it is in the same gear as the 48 million pixel model of the same level,The dynamic range performance is really good,It occupies a place in the first echelon of the same class。 At night, highlight suppression, shadow performance, and resolution are stronger than those of the Xiaomi Mi 10 Pro, but compared with the OnePlus 8 Pro, the sense of hierarchy is a little worse, and compared with the Find X2 Pro, the color reproduction is a little worse, and the HDR algorithm is too aggressive, and the whole picture will feel flat. Compared with the image quality, the problem of the film rate may be more obvious, whether the hand shakes or not determines the film rate and the quality of the film, as long as the hand does not shake, the night scene of the Xiaomi Mi 10 Ultra is the first echelon, and a hand shake will cause paste.
The 2x portrait lens is a medium focal length that is commonly used in daily life, and there are many scenes where the 2x zoom is pointed, and this lens is also particularly good for half-length photos. The Mi 10 Ultra's portrait mode maintains a high level in terms of color, cutout, and detail, but it doesn't support other camera options for the time being, and 2x full-body shots aren't as good as the main camera.
The 5x periscope light change belongs to the hardware of "there is no hanging", coupled with the IMX586 outsole CMOS, it performs better than vivo X50 Pro and P40 Pro in the 5x focal length, and is close to the Samsung S20 Ultra that also uses IMX586. As for 120x digital zoom, it is a marketing concept, and it is difficult to use it to take photos that can be seen.
The ultra-wide angle has added the night mode, the usability has been greatly improved, and there are no big slots, the main problem is that its position is too low, and when the ultra-wide angle is turned on when held normally, the fingers will inevitably enter the lens, and the position of the fingers needs to be adjusted.
In terms of battery life, Xiaomi Mi 10 Ultra is a 4500mAh graphene-based lithium battery, the discharge efficiency is slightly higher than that of ordinary lithium batteries, although there is a 120Hz refresh rate, but the screen resolution is FHD, the power consumption is lower than the 2K screen, and the 865 will not be particularly high in daily use, so the battery life is not a concern for Xiaomi Mi 10 Ultra.
In terms of charging, the Xiaomi Mi 10 Ultra is already the top level in the Android flagship, 100W wired charging can be charged from 0% to 100% in 25 minutes, and it is also compatible with a number of PPS high-power chargers, up to 45W, and also supports QC 5.0, and the charger of QC 5.0 is also expected to be above 100W in the future. The Xiaomi Mi 10 Ultra's 55W wireless charging is also faster than wired charging on many models, with charging from 0% to 100% in just 40 minutes.
