The K30 5G Extreme Edition is powered by a Snapdragon 768G processor, and the K30i is powered by a Snapdragon 765G processor, both with a 4500mAh battery and 30W fast charging.
The K30 Pro, K30 Pro Zoom Edition, and K30 Ultra Edition are the ones shown in the picture below, continuing to use a true full-screen display with a lift-up camera. Both the K30 Pro and K30 Pro Zoom Edition use a combination of a Snapdragon 865 Shen U and a 4700mAh battery + 33W fast charging, with the main difference between the two being the telephoto camera. K30 Extreme Edition is the K30 Pro's replacement "core" product, the processor is replaced with MediaTek Dimensity 1000+, the battery is reduced to 4500mAh, and it is equipped with stereo dual speakers for the first time, and the memory specifications are also castrated.
K30S Extreme Edition was officially released on October 27, 2020, equipped with Qualcomm Snapdragon 865 processor, the rear is a 64 million pixel main lens + 13 million pixel ultra wide-angle lens + 5 million pixel macro lens, the ultra-wide-angle lens uses the same K30 Pro model, but the 200W pixel depth of field lens has been cut, and the front is a 20 million pixel camera.

Redmi K40 series
On February 25, 2021, the Redmi K40 series went on sale, and Redmi K40, Redmi K40 Pro, and Redmi K40Pro+ were launched, and the metal middle frame was canceled in the whole series, and the plastic middle frame was installed as standard, and at the same time, the first game mobile phone of the K series, K40 Game Enhanced Edition, was born, and a Redmi K40S was also launched on March 17, 2022. So, the K40 series has released a total of 6 mobile phones.
Due to the very successful sales of the K30S Ultra, this time Redmi divided the model into three versions: standard version, Pro version, and Pro+, and the standard Samsung E4 substrate OLED cut-out screen with a refresh rate of 120hz can excite 900nit global maximum brightness, and the battery capacity is 4520 mAh. Among them, the standard version is equipped with a Snapdragon 870 processor, and the two Pro versions are equipped with Qualcomm's "Fire Dragon 888" processor, so the experience of the standard version is better than that of the two Pro versions, and it has become a "flagship" mobile phone.
Redmi's first K-series gaming phone has been adjusted to varying degrees for the ultimate gaming experience, not only using the metal middle frame back, but also adding a breathing light to the rear image module, and integrating pop-up "shoulder buttons" on the metal middle frame. The storage has been changed to LPDDR4X, which is lower than the standard version. The screen is adjusted to excite a Huaxing Optoelectronics screen with a brightness of less than 800ni, although the substrate of the screen is not as good as E3, but the touch sampling rate is higher. However, the phone uses a MediaTek Dimensity 1200 with a better experience than the Snapdragon 88, adding dual speakers tuned with JBL, increasing the battery capacity to 5065mAh, adjusting the wired fast charging to 67W, and optimizing the heat dissipation.
Redmi K50 series
On February 16, 2022, the first product of the K50 series was released, which is the second gaming phone of the K series, the Redmi K50 Esports Edition, and on March 17, 2022, the standard version of the Redmi K50 series K50 and the large cup K50 Pro products were released, and the Redmi K40S product was also released. On August 11, 2022, Redmi released the last product in the K50 series, the Redmi K50 Extreme Edition.
The Redmi K50 Gaming Edition debuts the CyberEngine ultra-wideband X-axis linear motor, which adds support for 1920hz high-frequency PWM dimming, and upgrades the previous generation's 2 JBL-certified speakers to 4, and reuses LPDDR5 for memory, with a reduced battery of 4700mAh but supports 120W fast charging. The configuration of the whole mobile phone is very good,But it still can't withstand the violent heat brought by the "Fire Dragon8 Gen1",Even if Redmi has equipped it with dual VC vapor chambers,But it is still powerless,So far, only 2 generations of Redmi's game mobile phone have been discontinued,Completely burned Redmi's game phone dream。
The K50 and K50Pro products of the Redmi K50 series were first released on March 17, 2022, and the main change of the K50 series compared with the previous generation K40 series is that it is equipped with the world's first mid-range god U Dimensity 8100 processor, which performs better than the Snapdragon 870 in terms of process technology, architecture, multi-core performance, GPU performance, and energy efficiency. The battery capacity has also been increased to a large 5500 mAh battery, and the screen has been replaced with a 2K screen. The Pro version is optimized on the ordinary version,The processor has been replaced by Dimensity 8100 to Dimensity 9000,In order to balance the relationship between large battery and fast charging,As well as the layout,5000mAhLarge battery is equipped with a surging P1 charging chip120W super fast charging,The rear main camera is replaced with a 108 million pixel (Samsung HM2) outsole sensor。
The K50 Extreme was released on August 11, 2022 and will be available in Mercedes · Mercedes-Benz's co-branded model, compared with the regular K50 series products, removes all game-related configurations (shoulder buttons, four Yang, dual VC, breathing lights, metal middle frame, super large motor, etc.), and these configurations are replaced with ordinary X-axis motors, double Yang, single VC, etc. K50 Extreme board also uses a custom straight screen with 1.5K resolution, the color depth of the screen is increased to 12bit, and the main camera that supports optical image stabilization exceeds 100 million pixels, and the under-screen fingerprint is also back online, and the processor does not continue to use Dimensity, but is replaced by a "firefighter" Snapdragon 8+, and the battery capacity and charging power are the same as those of the Pro version.
Redmi K60 series
The Redmi K60 series was released on December 27, 2022, and the naming is finally unified, with the cost-effective version being K60E, the standard version being K60, the large cup model being K60 Pro, and the extra-large cup model being K60 Extreme, of which the K60 Extreme Edition was released on August 14, 2023.
The K60E is actually a "core change" version of the K50, and there are only regular upgrades in terms of processing, with the Dimensity 8100 being replaced with the Dimensity 8200, and the performance gains are almost negligible. The K60 upgrade is more realistic, the processor has been replaced by a Dimensity 9000 to a downclocked version of the Snapdragon 8+, the main improvement is to replace the screen with a 2K screen exclusively supplied by Huaxing Optoelectronics, the local peak brightness can reach 1400nit, and K60 has also begun to support under-screen fingerprint and 30W wireless fast charging (the first time in the K series), and it is also equipped with OIS optical image stabilization, supporting VC liquid cooling and heat dissipation, Dolby Vision Atmos and other functions. The main change of the K60 Pro is that the processor is replaced with a high Snapdragon 8 Gen2, the memory is matched with the LPDDR5X+UFS4.0 (UFS3.1 for the beggar version)" combination, and the sensor is the same as the Xiaomi 13, and the image has also reached a high level. In terms of dual-band GPS, compared to the K60E and K60, the K60 Pro uses the full version.
The K60 Extreme Edition released on August 14, 2023 is equipped with a MediaTek Dimensity 9200+ flagship processor, equipped with a Pixelworks point-by-point X7 graphics chip, supports up to 24GB of RAM and 1TB of storage memory, uses a combination of LPDDR5X + UFS 4.0, and is also equipped with the new Fury Engine 2.0. The screen also supports a 144Hz refresh rate as well as a 1.5K resolution, and in the Genshin Impact Super Frame Superresolution concurrency test, it was claimed that "the average frame rate is as high as 143.4fps, which is almost full frame". In order to maximize the cost performance and compress the cost to the extreme, Redmi has canceled the wireless charging function. If you have a strong need for wireless charging, I recommend you to choose the K60Pro.
Redmi K70 series
On November 29, 2023, Redmi released its latest K-series, the Redmi K70 series. The model released this time follows the naming of the K60 series, and the cost performance is still the E version of the K70E, the standard version is the K70, and the large cup model is the K70 Pro.

It is equipped with Xiaomi Surging OS system, which is also the first time that Xiaomi Surging OS has landed on the Dimensity platform. Position yourself as the king of all-scenario performance.

Summary of the charging head network
Behind the 28 K series products released by Redmi is Redmi's keen insight into market development trends and in-depth understanding of consumer needs. They accurately grasp the needs of consumers for mobile phone performance, photography, battery life, screen, etc., and continue to meet these needs through technological innovation and product upgrades. At the same time, Redmi also pays attention to the design and quality of its products, and does its best in every detail, so as to attract more consumers' choices. In the future, we expect Redmi to continue to maintain this innovation and competitiveness, and continue to launch more excellent products. At the same time, we also hope that consumers will continue to support and pay attention to the Redmi brand and witness its growth and progress together.
However, Redmi is not resting on its laurels. They are always looking for new breakthroughs and innovations. Starting from the K50 series, Redmi began to pay attention to the comprehensive upgrade of the product, not only improving the performance, but also comprehensively optimizing the camera, battery life, screen and other aspects. The K60 has finally added the wireless charging function that users have dreamed of, and it is a private protocol of 30W wireless fast charging, which makes more users like Redmi K series mobile phones. In the K70 series, Redmi has introduced a new design concept and technological innovation, which has made the product reach a new height in all aspects, becoming a proper flagship level of "bucket machine", but the K70 series has cut wireless charging in order to balance the thickness of the machine, or for cost considerations. It is hoped that the follow-up K80 series can return to the embrace of wireless charging again, challenge the flagship beyond the level, and become a "true flagship" mobile phone.
