Xiaomi Redmi K90
- Significantly faster processor (Snapdragon 8 Elite)
- Ultra-fast 100W charging
- Potential for a superior display with LTPO technology
- Price likely to be higher than Poco F4
- Battery capacity currently unknown
Xiaomi Poco F4
- Excellent battery life (101h endurance)
- Proven performance with Snapdragon 870
- Potentially more affordable price
- Slower charging speed (67W)
- Older chipset compared to K90
Display Comparison
The Poco F4 boasts a bright display, peaking at 1003 nits, ensuring excellent visibility even in direct sunlight. However, the Redmi K90’s display specifications are currently unknown. Given the K90’s flagship positioning, we anticipate a comparable or superior panel, potentially incorporating LTPO technology for adaptive refresh rates and improved power efficiency. The Poco F4’s infinite contrast ratio is typical for OLED panels, but the K90 could offer further refinements in color accuracy and calibration.
Camera Comparison
Both devices feature photo and video capabilities, but detailed camera specifications are limited. The Poco F4’s camera system is known to be capable, but the K90’s potential is largely unknown. Without sensor size or aperture information, it’s difficult to make a direct comparison. However, given the K90’s higher-end positioning, it’s reasonable to expect a more advanced camera system with features like larger sensors and improved image stabilization. The inclusion of OIS on the K90 would be a significant advantage.
Performance
The core difference lies in the chipsets. The Redmi K90’s Qualcomm SM8750-AB Snapdragon 8 Elite (3nm) is a significant upgrade over the Poco F4’s Snapdragon 870 (7nm). The K90’s octa-core CPU, featuring Oryon V2 Phoenix L and M cores clocked up to 4.32 GHz, promises substantially faster processing speeds and improved efficiency compared to the 870’s Kryo 585 cores. The 3nm process node of the Snapdragon 8 Elite translates to lower power consumption and reduced thermal throttling during sustained workloads. While the Poco F4’s 870 is still capable, the K90 offers a generational leap in performance, particularly in GPU-intensive tasks.
Battery Life
The Poco F4’s endurance rating of 101 hours suggests excellent battery life, despite a potentially smaller battery capacity. The Redmi K90, however, features significantly faster 100W wired charging, utilizing PD3.0, QC3+, and PPS standards, allowing for a full charge in a fraction of the time compared to the Poco F4’s 67W charging (38 minutes to 100%). The K90 also offers 22.5W reverse wired charging, a feature absent on the Poco F4. While the K90’s battery capacity is unknown, the faster charging speeds mitigate concerns about potential battery life differences.
Buying Guide
Buy the Xiaomi Redmi K90 if you demand the fastest possible performance for demanding tasks like gaming, video editing, or running complex applications. Its advanced chipset and faster charging will appeal to power users. Buy the Xiaomi Poco F4 if you prioritize a balanced experience with reliable performance, long battery life (rated at 101 hours endurance), and a potentially more affordable price. It’s ideal for everyday use, media consumption, and casual gaming.
