As consumers pursue the "cost-effectiveness" of mobile phones, it is difficult to buy a mobile phone with balanced performance and imaging for less than 3,000 yuan. After all, no mobile phone brand can violate the consumer concept under the condition of limited cost. , the ability to change consumer attitudes.
Even so, among the many models, there are still outstanding mobile phones. For example: vivo S15, this mobile phone is priced under 3,000 yuan. It not only takes into account the performance of the mobile phone, but also achieves the best image quality at the same price. Vivo S15 is definitely the best choice besides performance!
The appearance is beautiful, and the screen is material
When it comes to mobile phones, appearance is indispensable. Appearance is always the best productivity of a product. In the face of an environment full of public models around the world, vivo has long been on the market. The Tianjie Cloud Window-style family-style design not only ensures personalization, but also enhances the appearance of the phone. The vivo S15 continues to adhere to the family-style design style, with only minor changes in details.
vivo S15’s Tianjie Cloud Window rear lens can give people a clean and simple feeling visually. The entire square lens module is embellished with metal of the same color as the body, and the built-in lens is also wrapped in a metal ring of the same color. The entire design is not obtrusive, but also adds the finishing touch and enhances the appearance.
The vivo S15 is also quite solid in terms of body materials, with an integrated aviation aluminum middle frame + AG fluorite frosted back cover. Such a configuration is currently uncommon at prices below 3,000 yuan. In fact, the in-hand experience is also very wonderful. The metal middle frame feels refreshing and cool in the hot summer. The AG fluorite frosted back cover not only does not have that rough and rough feel, but is delicate and silky. In terms of anti-fingerprints, The frosted after-feel effect is even better.
Although the vivo S15 has solid body materials and a good feel, the weight and thickness have become the machine’s negative points. The weight of previous generations of the S series was basically controlled at around 180g, and the thickness would not exceed 7.5mm. However, the weight of this S15 has soared to 197g, and the thickness has reached 8.08mm. Although the data is not very intuitive, users who are used to using thin and light mobile phones will definitely be a little uncomfortable.
After talking about the body design, let’s talk about the screen. The vivo S15 is equipped with a 6.62-inch OLED straight screen, and vivo has also made the upper, left and right borders of the screen equal width this time, so it is not too wide. Chin, the overall visual sense is very good. In addition, vivo S15 also designed the front lens hole to be very small, and placed a very delicate silver embellishment around the hole. Although this small design does not mean much, it shows that vivo takes the design details seriously. .
In addition to the polished periphery of the screen, the screen quality of vivo S15 is also remarkable. A Samsung E4 screen with high contrast, high color accuracy, and low power consumption has a local maximum brightness of up to 1,300 nits. Whether in bright sunlight or at night with insufficient light, vivo S15 can always present the clearest picture. At the same time, vivo S15 also supports a 120Hz refresh rate, which not only makes up for the shortcomings of previous generations of low refresh rate, but also witnesses the transformation of the S series. The
imaging chip V1+ is calibrated with Zeiss to create extraordinary samples. The
S series has always been vivo’s mid-range selfie imaging flagship. This phone’s imaging accomplishments have already surpassed most models in the same price range, and this time the S15 is no exception. . The vivo S15 is equipped with a 32MP single camera on the front and a 64MP main camera + 8MP wide angle + 2MP macro camera on the rear. The rear main camera supports OIS optical image stabilization and has super night scene blessing. Compared with the previous generation S12, the S15's front lens has been significantly changed. The dual camera has been replaced by a single camera, and the polar night flash has also been eliminated. So, what is the imaging quality of this machine?
We can see from the sample picture above that although the front lens of the vivo S15 is reduced to a 32MP single camera, the shooting effect is still excellent. The subject of the character is clear and natural, the background is blurred just right, and the details of the character are not missing. Not even the hairline is sticky.
Although the vivo S15 has canceled the bipolar night flash, it still retains the soft light ring. When the environment is dim at night, we can choose to turn on the soft light ring, so that the screen light of the mobile phone can illuminate our eyes. face. The picture above shows the effect of turning on and off the soft light ring. We can see that the effect is still very obvious. After the soft light ring is turned on, the face is brighter and the facial features are clearer and three-dimensional.
In addition, vivo S15 also adds beauty, aperture adjustment and stylized design to the camera. Beauty and aperture adjustment may be familiar to everyone, and stylized design allows you to choose different styles when taking selfies, which mainly include There are three categories: classic, light and shadow, and filter, and these three categories correspond to styles such as freshness, texture, garden, pop comics, starlight, green and orange , rainbow, macaron, evening breeze, island, etc. In short, style The number is beyond imagination.
Thanks to the ultra-high resolution of the 64MP main camera, the vivo S15 performs quite well in daytime sample photos with sufficient lighting. The color of the object itself can be highly restored, basically close to what the naked eye can see. At the same time, this phone also retains details. It's very good, and after the picture is enlarged, there is no obvious blur, focus, etc., which greatly facilitates secondary editing and creation.
As we all know, when shooting in a cloudy environment, the sky will be darker, and because the clouds are fluid, the colors are not uniform. This environment takes great care of the mobile phone's own algorithm. The performance of vivo S15 in this environment is pretty good. Although the colors of the buildings are still too dark, the details are well preserved and the tones are relatively uniform.
Compared with the daytime when there is sufficient light, the night environment is more complex. Not only does the hardware need to meet the standards, but the algorithm of the mobile phone is also considered. The performance of the vivo S15 at night is also pretty good. This phone can effectively suppress highlights and maximize the shooting rate. The sample photos are not only uniform in color, but also the details are well preserved, and the dark areas are pure and natural. There is no noise, the picture is clear and interesting, and the overall shooting quality is still very good.
Snapdragon 870 Peak Edition + Gaming-level Bionic Cooling, the performance is very impressive
Different from previous generations, this time the vivo S15 has also significantly improved in terms of performance. It is not only equipped with the Peak Edition Snapdragon 870 processor, but also With e-sports-level bionic heat dissipation, the S15 series has relatively strong performance, and is also officially defined by vivo as the strongest S series in history. So, is this really the case?
In accordance with international practice, we will first conduct an entertainment rabbit benchmark for vivo S15. Based on the actual test, we can see that vivo S15 is still somewhat different from the benchmark score at the press conference. The running score of this mobile phone reached 77W+, but in actual testing, the running score of S15 was only around 74W. Although the running score did not meet expectations, 74W has surpassed most models with the same processor.
Of course, whether the game card is stuck or not, ultimately the frame rate and have the final say. vivo S15 supports Honor of Kings 120 frames. After running the game for half an hour, we started doing the frame rate test of Honor of Kings. We can see that during the 10-minute game, vivo S15 ran very smoothly, with the frame rate around 119-120. Although there was a slight frame drop between FPS, there was no lag in the actual gaming experience.
Compared with Honor of Kings, vivo S15 does not adapt to Peace Elite’s high frame rate , so it only supports 60 frames. From the picture above, we can see that in the 10-minute game, although the frame rate also has small frame drop fluctuations, the frame rate of the vivo S15 is basically around 60 FPS. Relatively speaking, the S15 will be more stable when running Peace Elite. , the game is also extremely smooth.
finally tested Genshin Impact . The frame rate of this game fluctuated greatly, and there was also a frame rate lock in the middle.The frame rate can be maintained at 60 FPS for the first 15 minutes, but the frame rate fluctuates greatly. After 15 minutes, the game frame rate drops directly from 60 FPS to 40 FPS, which lasts for 10 minutes, and then rises to 60 FPS. , but after only 3-4 minutes it dropped to 40 FPS and finally started running at 60 FPS again. However, the game experience is pretty good, there is no significant lag, and the perception is not strong.
As we all know, the reason why mobile phones experience frame rate locking is closely related to the temperature of the mobile phone. The reason why Snapdragon 870 will still be widely used by mobile phone manufacturers this year is due to its excellent temperature control and energy consumption. Inseparable relationship. For this reason, Xiao M measured the surface temperature of the machine after running Genshin Impact for 1 hour. When the room temperature was 27.4℃, the temperature of the machine was 39.4℃. As for the performance, everyone can judge for themselves!
4500 mAh battery + 66W flash charge, can carry and play
The reason why the weight of vivo S15 can reach 197g is partly due to its appearance, but the battery must also contribute. This phone is equipped with a 4500 mAh battery and 66W wired fast charging. Both battery capacity and charging power are greatly improved compared to the previous generation S12. So, what is the actual battery life performance of this phone?
Through actual measurement, when the mobile phone battery is at 100%, start watching online 1080P videos, adjust the sound and screen brightness to 50% respectively, vivo S15 loses 1% of power in 10 minutes, 2% of power in 20 minutes, and 30 minutes of power loss. 3%, 7% power loss in 60 minutes, and the power dropped from 100% to 20% in 12 hours and 50 minutes. This battery life is still quite good. Compared with the Snapdragon 888 model with the same battery capacity, it is at least 3 hours longer. In terms of battery life, the reason why the S15 can achieve such good results is mainly because the power consumption of the Snapdragon 870 is indeed lower, and also because vivo’s optimization of battery life is also good!
Charging power is the focus of the upgrade of the S15 series, and the actual test is acceptable. Start charging the phone when the battery is at 20%. Charge it to 33% in 5 minutes and charge 13%. Charge to 45% in 10 minutes and charge 25%. Charge to 87% in 30 minutes and charge 67% in 43 minutes. The battery is charged to 100%, and the trickle charge is completed in 45 minutes. The entire charging process is not too fast, but it is not slow either, and is basically at the expected level of 66W.
is written at the end
Overall, this vivo S15 has indeed improved significantly compared to previous generations. This phone not only inherits the excellent images of previous generations, but also takes into account performance. Among cost-effective models, vivo S15 is undoubtedly more comprehensive. If your purchase budget is around 3,000 yuan, and your demand for a mobile phone is a balance of performance and imaging, then vivo S15 is definitely a good choice. Of course, if you just play games and don’t have much demand for images, then choose a cost-effective model!
