In the current domestic mobile phone market, despite manufacturers' push into the high-end segment, it is cost-effective models that continue to drive sales. This isn't because users of cost-effective phones can't afford flagship devices; rather, many people don't have stringent requirements for daily phone use. Cost-effective models fully meet their needs at a fraction of the cost, making them a more rational choice for most. Among these models, Redmi stands out as a favorite, particularly with its well-balanced K80 series in terms of comprehensive functional configuration.

For instance, competitors struggle to match the K80 series' combination of a 2K screen, ultrasonic fingerprint recognition, top-tier waterproofing, and a large battery at a comparable price. While its strengths are evident, the series' imaging capability remains a notable shortcoming. Recognizing this, Redmi appears poised to address this issue in the next generation.

According to recent leaks, the Redmi K90 series will indeed tackle its camera shortcomings, though specifics remain unclear. It's unclear whether this will involve new lenses or an improvement in existing ones. Personally, enhancing existing lens quality seems more likely. For example, the standard version might retain the same main camera pixel count but feature a slightly upgraded sensor. The ultra-wide-angle lens, however, is poised for a significant upgrade; an 8-megapixel lens is no longer sufficient, and I predict a doubling of the pixel count. The Pro version, meanwhile, might switch to a periscope telephoto lens without an increase in pixel count.

The CPU processor will also see routine upgrades. The standard version will adopt the Snapdragon 8 Ultimate, while the Pro version will step up to the Snapdragon 8 Ultimate Gen 2. Their capabilities are undoubted, but what's noteworthy is the advanced release date. While the K80 series debuted in late November, the K90 is expected in October, indicating Redmi's intent to gain a first-mover advantage. If competitors lag behind, Redmi could capture a significant market share.

However, as a sub-brand, Redmi's upgrades shouldn't encroach on Xiaomi's digital flagship models. While the standard version poses no threat, the Pro version's functional configuration edges closer to Xiaomi's top-tier flagships, and its earlier release date could sway potential Xiaomi 16 buyers. Xiaomi, however, is likely prepared for this. The Xiaomi 16 will undoubtedly offer capabilities unavailable in the K90 Pro.

Battery life will also see improvements. The K90 is likely to boast a capacity exceeding 7000mAh, with the K90 Pro at least reaching 6500mAh. Moreover, as AI becomes a trend across the internet industry, and mobile phones serve as key carriers, the K90 series will certainly optimize in this area.

Ultimately, price remains a key concern. If the K90 series, with its addressed camera shortcomings, maintains its starting price, it will exert considerable pressure on competitors.
