As a model listed in 2021, the relative cost performance of the Redmi K40 has made it the shoulder handle of the Snapdragon 870 mobile phone that year, and the sales volume is gratifying, but it has to face the practical problem of delisting, and even Lu Weibing has sent a weibo for the delisting of the Redmi K40 to praise the Redmi K40 as the "flagship machine goalkeeper". However, at last night's press conference, Redmi launched the replacement of K40, Redmi K40S, so Redmi K40S should be regarded as an upgraded version of Redmi K40, right?
I personally feel that I can't talk about it, let's first look at the changes in the Redmi K40S,
First, compared with the Redmi K40, the Redmi K40S has more optical image stabilization functions, the main camera still uses a 48 million pixel lens, the main camera sensor is still SONY IMX582, the ultra-wide angle lens is still the 8 million pixel lens of the SONY IMX355, but the rear 5 million pixel telephoto macro lens is downgraded to a 2 million pixel macro lens, which is the most uncomfortable place.
Second, the Redmi K40S wired fast charge has increased from 33W of the Redmi K40 to 67W, and the battery capacity is 20mAh less than that of the Redmi K40, and the change is not large.
Other hardware parts, the Redmi K40S and the Redmi K40 have remained consistent without much change, such as the continuation of the Qualcomm Snapdragon 870+ UFS 3. 1 flash memory + LPDDR5 memory combination, this combination still belongs to the high version of the same specifications of the mobile phone; the screen is still the flagship machine level, using a 6.67-inch, Samsung E4 material AMOLED screen, support 120Hz high refresh rate, the display effect is also relatively excellent; X-axis linear motor, multi-function NFC, dual speakers, infrared remote control, etc. are also retained one by one.
Compared with the improvement of wired fast charging, the rear camera part can be said to be not rising but falling, and this should also be the reason why the price of Redmi K40S is relatively low, but Redmi K40S is not an upgraded version of Redmi K40, at most it is only the successor of Redmi K40. If you have a limited budget and have certain requirements for performance but don't care about the imaging performance of the phone, then you can consider the Redmi K40S.
