The Xiaomi Mi 11X and Poco F4 both leverage the proven Qualcomm Snapdragon 870 5G chipset, but cater to slightly different priorities. The Mi 11X, released earlier, established a strong baseline, while the Poco F4 aims to refine the experience with faster charging and a brighter display. This comparison dissects the nuances to determine which device delivers the best overall package.
🏆 Quick Verdict
For most users, the Poco F4 emerges as the superior choice. Its significantly faster 67W charging (38 minutes to full) and brighter 1003-nit display offer tangible benefits over the Mi 11X's 33W charging and unspecified display brightness. While both share the same core performance, the Poco F4’s improvements justify the potential price difference.

Xiaomi Mi 11X
- Potentially lower price point
- Capable Snapdragon 870 performance
- Solid endurance rating
- Slower 33W charging
- Display brightness likely lower than Poco F4
- Limited camera information
Xiaomi Poco F4
- Significantly faster 67W charging
- Brighter 1003-nit display
- Potentially improved software and camera processing
- May be more expensive than Mi 11X
- Shares the same Snapdragon 870 chipset

Display Comparison
The Poco F4 boasts a considerable advantage in display technology, achieving a measured peak brightness of 1003 nits. While the Mi 11X’s display specifications are not provided, this difference is significant for outdoor visibility. Both displays feature an infinite (nominal) contrast ratio, suggesting deep blacks. The lack of information on the Mi 11X’s panel type (AMOLED vs. LCD) and refresh rate hinders a complete comparison, but the Poco F4’s brightness alone makes it the winner for users who frequently consume content outdoors or in brightly lit environments.
Camera Comparison
Both devices are listed as having Photo/Video capabilities, but detailed camera specifications are absent. Without sensor size, aperture information, or details on image processing algorithms, a meaningful comparison is impossible. It’s reasonable to assume the Poco F4, being a newer model, may benefit from improved software processing and potentially a more capable main sensor, but this remains speculative without concrete data. The absence of details regarding OIS (Optical Image Stabilization) on either device further complicates the assessment.
Performance
Both the Mi 11X and Poco F4 are powered by the Qualcomm SM8250-AC Snapdragon 870 5G (7 nm) chipset, featuring an identical octa-core CPU configuration (1x3.2 GHz Kryo 585, 3x2.42 GHz Kryo 585, and 4x1.80 GHz Kryo 585). This means CPU and GPU performance will be virtually indistinguishable in most tasks. The real-world performance will depend on RAM configuration and thermal management, which are not specified in the provided data. However, given the 870’s efficiency, both phones should handle demanding games and applications without significant throttling, though the Poco F4’s potentially improved cooling (based on brand reputation) could offer a slight edge in sustained performance.
Battery Life
Both the Mi 11X and Poco F4 achieve an endurance rating of 101 hours, suggesting similar battery life under comparable usage scenarios. However, the Poco F4’s 67W wired charging capability is a game-changer, achieving a full charge in just 38 minutes, compared to the Mi 11X’s 52 minutes with its 33W charging. This faster charging significantly reduces downtime and provides a more convenient user experience. While both support PD3.0 and QC3, the wattage difference is the defining factor here.
Buying Guide
Buy the Xiaomi Mi 11X if you prioritize a potentially lower price point and are comfortable with slower charging speeds. It remains a capable performer for everyday tasks and moderate gaming. Buy the Xiaomi Poco F4 if you value faster charging, a brighter and more vibrant display, and a slightly more refined overall experience, even if it means spending a bit more.
Frequently Asked Questions
❓ Does the Poco F4's faster charging affect battery health over the long term?
While faster charging can theoretically contribute to slightly increased heat, modern charging algorithms and battery management systems mitigate this risk. The Poco F4's charging circuitry is designed to optimize charging speed while protecting battery health, and the difference in long-term degradation compared to the Mi 11X's slower charging is likely to be minimal.
❓ Is the Snapdragon 870 in these phones still capable of handling demanding games like Genshin Impact?
Absolutely. The Snapdragon 870 remains a very capable chipset for gaming, even in 2024. Both the Mi 11X and Poco F4 should be able to run Genshin Impact at medium to high settings with stable frame rates. Thermal management will play a role, but the 870 is known for its efficiency.
❓ Given the identical endurance ratings, will I notice a real-world difference in battery life between the two phones?
The endurance rating represents a standardized test. Real-world battery life will depend on your usage patterns. However, the Poco F4’s faster charging means you’ll spend less time tethered to a charger, effectively giving you more usable battery time throughout the day, even if the total capacity is similar.
