[News]Xiaomi announces Redmi Note 5 in China

Featuring flagship-level photography capabilities for great photos

BEIJING, China, 16 March 2018 — Global technology leader Xiaomi officially announced Redmi Note 5 in China today, which features flagship-level photography capabilities. With a dual camera featuring a large 1.4μm-pixel sensor, AI camera features, and an LED Selfie light for its front camera, Redmi Note 5 is a powerful device that takes amazing photos anywhere, at any time.

Redmi Note 5 also marks the debut of the Qualcomm Snapdragon 636 platform in China. It will be available in China on 20 March starting from RMB 1099.

Clearer images and faster focusing even in low light

Redmi Note 5 sports a dual camera setup, a combination usually adopted only in flagship smartphones. The main 12-megapixel sensor features large 1.4μm pixels, which can capture more light and deliver better results under low-light conditions.

The camera is also armed with 2PD (dual photodiode) autofocus — a technology commonly seen in professional dSLR cameras, which results in a much faster autofocus speed. Every single pixel of the main 12-megapixel sensor contains two photodiodes (which convert light into current that can be measured) – resulting in 24 million photodiodes in total, which is nearly 30 times more than the number of photodiodes of traditional PDAF-enabled sensors of the same resolution. This allows the sensor to measure phase differences effectively, improving Redmi Note 5’s autofocus speed dramatically.

The front camera of Redmi Note 5 sports a 13-megapixel sensor, complemented by an LED Selfie light. When Portrait Mode is engaged, both the front and rear cameras come with Xiaomi’s latest Beautify 4.0 mode, which has different effects enhanced by AI calculations for a natural look similar to having an expert makeup session. Even without a second sensor, the front camera achieves a great bokeh effect in Portrait Mode thanks to AI technology that helps to isolate the subject from the background.

Redmi Note 5 also uses facial recognition for unlocking the device, which is based on AI technology, enhancing the accuracy of identification for a more secure system.

China debut of Qualcomm Snapdragon 636

Redmi Note 5 uses Qualcomm’s latest Snapdragon 636 platform based on the 14nm manufacturing process. Its Kryo 260 architecture, 1.8GHz maximum clock speed, and the Adreno 509 GPU ensure amazing performance. Compared to Qualcomm Snapdragon 625, Snapdragon 636 has a 40 percent increase in performance — gamers can enjoy demanding 3D games on Redmi Note 5 with no worries.

Redmi Note 5 is the first device in the Redmi family to use up to 6GB of LPDDR4X RAM, usually only found on flagship devices. With more RAM, Redmi Note 5 can run more apps simultaneously and switch between programs even more smoothly.

Other features of Redmi Note 5 include a 5.99 inch FHD+ 18:9 full screen, large 4000mAh battery and support for fast charging. Equipped with the latest MIUI 9 operating system, Redmi Note 5 also comes with full screen display gestures so users can maximize the display area by completely hiding the navigation bar.

Redmi Note 5 comes in three versions: 3GB + 32GB, 4GB + 64GB and 6GB + 64GB, at RMB 1099, RMB 1399 and RMB 1699 respectively. It is available in four colors — Lake blue, Rose gold, Gold and Black. A simple and elegant TPU case will be included in the box with every Redmi Note 5.

Redmi Note 5 is the counterpart of Redmi Note 5 Pro, first launched in India in February. Redmi Note 5 features slight differences in specifications, and it will be available globally at a later date, with details in local markets to be announced individually.

Dual Cameras Come of Age

Smartphone devices with a dual-camera feature aren’t new by any stretch of imagination. However, only recently have dual cameras started to grab consumers’ attention.

Dual-camera phones have become much more powerful and affordable in the past few years. That said, it’s important to note that there are variations in the kind of implementations on the market. With an array of options at camera makers’ disposal, we have spotlighted the different dual-camera features available.

1. Color + Color

The advantage of the color + color camera setup is that it allows the smartphone to capture more light data than a single camera would; it’s basically built on the idea that “two is better than one.” Our first dual-camera smartphone, the Redmi Pro utilized this arrangement.

Another popular case for this arrangement was 3D pictures and video, which again didn’t happen to be a favorite with consumers.

Other smartphones offer a color + color sensor arrangement which leverages narrow- and wide-angle lenses to offer some flexibility to consumers.

2. Color + monochrome

Another popular dual-camera design is a color + monochrome lens. The main advantage of this arrangement is the level of detail captured in every picture; data from both sensors is combined, resulting in pictures with a higher level of detail than standard single camera phones. Most phones with this set-up also allow the user to use the monochrome sensor as a standalone feature.

Until about a year ago, the color + monochrome feature was only found on high-end phones, but is now becoming increasingly popular on phones that are affordable to a greater number of people, for example, Mi 5S Plus.

3.Wide angle + telephoto

While other arrangements couldn’t quite satisfy consumers in producing good enough photos, this wide angle + telephoto implementation helped deliver what consumers really want—pictures that can get thousands of likes on social media.

This arrangement allows smartphones to focus on subjects in the foreground while blurring the background, giving pictures an effect that was previously only possible on a DSLR. The result is achieved by the combination of a wide-angle lens along with a telephoto, which work in conjunction to bring out pictures with a blurred background. Other implementations do achieve this effect mainly through software, but the wide angle + telephoto setup will produce a more natural look.

Because of the hardware involved, this implementation is also the most expensive between the three, and generally produces images that are most pleasing (out of the arrangements mentioned here) to consumers’ eyes. Mi 6 and Mi A1  as well as iPhone 8 Plus are some examples of phones that use the aforesaid arrangement.

Without a doubt, advancements in mobile photography technology will result in even better dual camera solutions in smartphones. The possibilities are endless, and we will continue pushing boundaries in this area.
