As a mid-term facelift, the performance of the iPhone Xs is bound to be better than the iPhone X, but the problem is that in terms of actual experience, the upgrade of the Xs is not significant enough to make X users have the urge to change their phones, and after the launch of iOS 12, the smoothness of the old iPhone has also been greatly improved, and it is even difficult for Xs to attract 8P users to change phones. Apple is also aware of this problem, so the official simply stopped selling the iPhone X and let the operator sell it, but at the same time retained the previous generations of products, completing a very "ingenious" product layout.
According to Apple's three-year convention, the Xs series has only very slight differences from the X in terms of id appearance, for example, two antennas have been added at the bottom, and the number of holes in the microphone has changed, and the more obvious differences can only be reflected by the screen size of the Xs Max and the newly added gold.
The Xs series still has a good grip, the screen size of the Xs Max is larger, and the size of the whole machine is the same as that of the 8 Plus, which is easy to get used to in terms of operation, but the weight of the Xs Max has reached an unprecedented 208g, and after adding the phone case and film, it can easily act as an Apple brand mobile fitness equipment, which is not suitable for long-term holding.
Apple's new products will always be said to be the strongest glass in the industry, but in fact, it does not score high in the category of fall resistance, in the roller test of "Consumer Reports", the iPhone Xs Max after 50 falls, the editor scored "Very Good", and the Samsung Note 9 was "Excellent", after 100 falls, the editor only gave a "Poor" evaluation, while the Samsung Note 9 is still "Excellent", therefore, It is recommended to prepare a phone case for your Xs.
The XS also achieves IP68 water resistance, the sealant between the screen and the bezel has been widened, and the opening position is still sealed with rubber rings to resist water. Apple advertised at the press conference that the Xs can be left underwater for 30 minutes, and it can also resist the splash of juice and coffee, which is more than enough for daily use, but don't test its water resistance too much.
The XS continues to use the Super Retina OLED screen, still maintaining a relatively wide notch, and 85%, which is not a high screen-to-body ratio. XR will use LCD screens, so that the LCD party that will never be a slave will also have a reason to buy a new iPhone. In terms of screen-to-body ratio, Chinese brands are still trying to be a little more diverse, and it seems that Apple is a bit complacent.
The Xs screen has been well received by all parties, and DisplayMate said that it is one of the best OLED displays in the smartphone world after testing the Xs Max. The specific indicators are: color accuracy of 0.8 JNCD, full-screen brightness of 660Nit OLED mobile phone, peak brightness of 769Nit, contrast ratio (1,000,000:1), and screen reflectivity (4.7%). Not only does the Xs perfectly support the DCI-P3 color gamut and the sRGB color gamut, but the color management can automatically switch between these two modes depending on what is displayed on the screen.
In the description of the iPhone X, we focused on Face ID, but with the current technical level of various manufacturers, there is no very significant difference in the experience of using Face ID, the main difference is in security. Most mobile phones in the Android camp are still using 2D facial recognition, and a few will use 3D structured light, but they are also mainly coded structured light, Apple's speckle structured light will project 30,000 light points, the amount of computing is very large, and the overlap rate is only 1/1000000, which is still the most secure in the industry.
Xs's face unlock is a little faster than X, and it also supports Face ID with two faces, but it still doesn't support landscape screen unlocking, and there is a certain probability that it can't be unlocked while lying on the bed.
The Xs series is powered by Apple's latest A12 Bionic processor, and as always, the A12 will be the most powerful SoC in the mobile phone industry for a long time. The two big cores of the CPU are called Vortex, 2.5GHz, and the four small cores are called Tempest, 1.59GHz, using the 7nm process, and the chip size is smaller than that of A11. According to Anandtech's tests, the A12 is far ahead of the Snapdragon 845 and Kirin 970 in almost all test items, and even the 2.7GHz Exynos M3 is much worse than the Vortex, and even the Snapdragon 855 and Kirin 980 only close the gap a little.
In terms of GPU, Xs uses a 4-core G11P, which is officially said to have a 50% performance improvement compared to A11 GPU, in addition to the poor performance in 3DMark, A12 in GFXBench 5.0 Aztec Ruins, compared with A11, there is also a 50% improvement, and the results in other projects are a huge gap with the Android camp. The GPU's performance is quite strong and very stable, with minimal frame rate fluctuations in large games, and although the throttling is more severe when the body is hot, the performance per watt is still very good, reaching 20.18fps/W in Manhattan 3.1 and 11.99fps/W in Snapdragon 845. Because the performance of the CPU and GPU is extremely good, it is possible to directly use the power-saving mode in daily life, although the CPU and GPU will be downclocked, but the gap between the performance and the A11 is not large, and it can also increase the battery life.
In terms of photography and videography, the A12 also has an advantage, using two 12-megapixel cameras with optical image stabilization, Sony's CMOS, and the main camera has been increased from 1.22 microns to 1.4 microns. With an overall score of 105 on the DxO Mark, the Xs scored 110 in the Photo section and 96 points in the Video section, ranking fifth, and the Huawei P20 pro is still in first place. In actual shooting, Xs's Smart HDR can do what you see is what you get, and you don't need to worry about the image deviation after pressing the shutter, which requires a lot of computing to do. The Xs's dynamic range in high-contrast scenes is significantly improved compared to the iPhone X, and it is also a very top presence in the mobile phone field. Among the flagships, Xs is still inferior to Huawei P20 pro in terms of night scenes, and the zoom function also has a lot of room for improvement, while the front camera, which has always been based on realism, has been exposed to its own dermabrasion effect, losing Apple's unique advantages.
Soon after the release of the Xs, a large number of users complained about the bad signal and pointed the finger at the Intel baseband, but this has little to do with the Intel baseband, because the iPhone 8 has begun to use the Intel baseband on a certain percentage of models, and the main problem is the antenna. Although this generation of iPhones has increased to 4 antennas, the FCC test report shows that the XS and XS Max have low "equivalent isotropic radiated power" (EIRP), and the Xs has even worse signal power than the iPhone 8 in various frequency bands.
Apple added dual SIM dual standby function to mobile phones for the first time, but only Xs Max and XR have this feature, and Xs does not support it. Supporting dual SIM dual standby itself is an advantage, but it does not currently support dual VoLTE, and the use experience in China also has a lot to do with the operator, only the main card is mobile/Unicom, and the secondary card is Unicom can be 4G 3G standby, and the secondary card in other cases is 2G standby, which does not support dual telecommunications, and there may be no service when the telecom is a secondary card.
In terms of charging range, the Xs has improved over the iPhone X, with a battery capacity of 2658mAh for the Xs and 3174mAh for the Xs Max. Because the overall power consumption of the screen is high, the battery life of Xs is still a weakness, and there is pressure to use it for a day moderately, even if it is Xs Max, it is still not enough for heavy users. iPhone Xs supports wireless charging and fast charging, but the original factory is only equipped with a 5W charging head, Xs Max takes 3 hours to fully charge, and the 10W charging head of the iPad can be fully charged in about 2 hours.
