Global variants of Xiaomi 12X and Redmi 10 2022 have received European conformity certification, hinting at their imminent launch. Recall that last month Xiaomi introduced the Xiaomi 12X, Xiaomi 12 and Xiaomi 12 Pro smartphones in the Chinese market. The global variant of Xiaomi 12 recently appeared on the Geekbench certification database. Now the global variant of Xiaomi 12X has appeared on the Xiaomi Global website.
According to previous reports, the Chinese tech giant is planning a global launch of the Xiaomi 12, Xiaomi 12 Pro and Xiaomi 12X smartphones in late February or early March 2022. Xiaomi 12 and Xiaomi 12X feature a 6.28-inch Full HD+ AMOLED display with a 120Hz refresh rate, Xiaomi 12X features Snapdragon 870 mobile platform. Xiaomi 12 and Xiaomi 12X have a 4500mAh battery that supports 67W charging 67 W.
The Xaomi 12X smartphone is equipped with a main 50-megapixel Sony IMX766 camera with optical stabilization, as well as two additional cameras with a resolution of 13 and 5 megapixels. The front camera is 32-megapixel.
The Google Play Console database confirms that the upcoming Redmi 10 2022 is equipped with a Full HD + screen, a MediaTek MT6769 single-chip system and 6 GB of RAM. The phone will run Android 11. The smartphone will have a 6.5-inch IPS LCD display with a refresh rate of 90Hz and a 5000mAh battery. Redmi 10 (2022) should receive a main camera with OmniVision OV50C40 or Samsung S5KJN1 image sensors with a resolution of 50 MP. He will also receive an 8-megapixel Sony IMX355 sensor and a 2-megapixel GC02M1B or OmniVision OV02B1B.
iPhone totally dominates the list of best-selling premium smartphones
Despite the fact that the smartphone market as a whole continues to decline, the segment of expensive models is growing. According to Canalys, in the first quarter of this year, sales of smartphones with a price of $ 500 grew by 4.7%, while the overall market sank by 13.3%.
As a result, premium devices accounted for 31% of all smartphone sales, and it seems that this is the best-selling segment at the moment!
And dominates in this segment, of course, Apple. In the list of best-selling smartphones priced at $500 and above, the first four places are occupied by the iPhone, with the iPhone 14 Pro Max at the top. Fourth place was taken by the Samsung Galaxy S23 Ultra, the fifth was the iPhone 14 Plus, followed by the Galaxy S23, and behind it, curiously, the iPhone 12. Moreover, the iPhone SE is also on the list, and of the devices from other manufacturers, there are only Xiaomi 13 and Huawei Mate 50.
A 10-cent clip on a smartphone will measure blood pressure as well as a sphygmomanometer
Scientists at the University of California – San Diego have created a very useful yet tiny device called the BPClip. It is a clip that is attached to a smartphone and allows you to measure blood pressure. The device is made of ordinary plastic, it can be printed on a 3D printer, while the cost of one copy will be only 80 cents, and with mass production – even 10 cents. It turns out that the BPClip is much cheaper than a conventional blood pressure monitor with a cuff, and the measurement accuracy is almost the same, experts say.
The BPClip needs to be attached to the corner of the smartphone in such a way that the small hole in it is located above the lens of the built-in camera of the mobile device, and the light guide covers the flash. The user has to press on the hole clip with a fingertip: the spring provides resistance, allowing readings of pressures made with different strengths. With each press, the smartphone camera takes a picture of the fingertip illuminated by the flash: each image will be shaped like a red dot. Its diameter increases as more pressure is applied, and the color becomes brighter depending on the volume of blood in the finger.
The smartphone app then analyzes the size and brightness of the dot in various photos and determines the user’s current systolic (highest) and diastolic (lowest) blood pressure. The scientists conducted laboratory tests on 24 volunteers and it turned out that the measurements taken by BPClip are about the same as when using a traditional cuffed blood pressure monitor. So far, the medical gadget has only been connected to the Google Pixel 4, but its creators are already working on compatibility with other smartphone models. American scientists consider the main advantages of their development to be low cost, availability and ease of use: BPClip does not require configuration and can be used by anyone anywhere, without the need to visit a medical facility.
Arm introduced the Immortalis-G720 GPU, which may not appear on smartphones at all
In addition to the new Cortex-X4 supercore, Arm also introduced the new Immortalis-G720 GPU along with the Mali-G720 and Mali-G620 junior solutions.
Immortalis-G720 can have 10 cores or more, Mali-G720 can have 6 to 9 cores, and Mali-G620 can be configured with up to 5 cores.
Overall, Arm talks about a 40% reduction in memory bandwidth usage and a 15% performance boost.
It is also worth noting that the Immortalis-G720, as befits a fresh flagship solution, has a ray tracing acceleration unit, but, interestingly, the Mali-G720 can also have it, but is not required to. This is an explanation of Arm itself, probably meaning that it is physically present in the GPU, but SoC manufacturers can turn it off.
Separately, Arm notes the Immortalis-G720 graphics core’s support for deferred vertex shading and the presence of a 2x MSAA anti-aliasing module.
It is also worth noting that the Immortalis-G715 GPU is used, apparently, only in the SoC Dimensity 9200/9200 Plus. And if MediaTek does start using Nvidia GPUs for its new top-end SoCs, it’s unclear if there will be another company that will bring the Immortalis-G720 to smartphones, as Qualcomm has its own GPU and Samsung continues to partner with AMD.
