Xiaomi Poco F6
- Excellent battery life (10:36h active use)
- Bright 1218 nits display
- Competitive price point
- Snapdragon 8s Gen 3 is outperformed by Dimensity 9300+
- Slower 90W charging
Xiaomi Redmi K70 Ultra
- Superior performance with Dimensity 9300+
- Ultra-fast 120W charging (24 minutes to full)
- Likely more advanced camera system
- Battery life potentially lower than Poco F6
- May command a slightly higher price
Display Comparison
Both phones feature displays suitable for multimedia consumption, but the Poco F6 boasts a measured peak brightness of 1218 nits. While the K70 Ultra’s display specs aren’t provided, Xiaomi typically equips its ‘Ultra’ models with high-quality panels. The absence of LTPO technology in either device suggests both will rely on adaptive refresh rate switching rather than variable refresh rates for power saving. The Poco F6’s brightness advantage will be noticeable in direct sunlight, offering better visibility.
Camera Comparison
Without detailed camera specifications, a direct comparison is limited. However, given the ‘Ultra’ branding, the K70 Ultra likely features a more sophisticated camera system with a larger sensor and potentially optical image stabilization (OIS). Xiaomi typically prioritizes camera capabilities in its ‘Ultra’ line. The Poco F6, while capable, likely focuses on providing a solid, all-around camera experience rather than pushing the boundaries of mobile photography. The absence of information on lens apertures and sensor sizes makes a definitive judgment impossible.
Performance
The core difference lies in the chipsets. The Redmi K70 Ultra’s MediaTek Dimensity 9300+ features a unique CPU configuration with 1x 3.25 GHz Cortex-X4, 3x 2.85 GHz Cortex-X4, and 4x 2.0 GHz Cortex-A720 cores. This contrasts with the Poco F6’s Qualcomm SM8635 Snapdragon 8s Gen 3, which has 1x 3.0 GHz Cortex-X4, 4x 2.8 GHz Cortex-A720, and 3x 2.0 GHz Cortex-A520 cores. The K70 Ultra’s inclusion of *three* Cortex-X4 cores suggests a performance edge in multi-threaded tasks. The 4nm fabrication process is shared by both, but the Dimensity 9300+’s architecture appears optimized for sustained performance, potentially mitigating throttling during extended gaming sessions. The K70 Ultra’s CPU clock speeds are also slightly higher across the board.
Battery Life
The Poco F6 delivers an active use battery score of 10:36h, indicating respectable endurance. The K70 Ultra’s battery capacity is not specified, but its 120W wired charging (100% in 24 minutes) significantly surpasses the Poco F6’s 90W charging (2-100% in 35 minutes). This faster charging speed is a major advantage for users who frequently need to top up their battery quickly. While the Poco F6’s battery life is good, the K70 Ultra’s faster charging could offset a potentially smaller battery capacity.
Buying Guide
Buy the Xiaomi Poco F6 if you need a balanced device with solid performance, a bright display, and excellent battery life for everyday tasks and moderate gaming. It’s ideal for users who value efficiency and don’t necessarily demand the absolute highest frame rates. Buy the Xiaomi Redmi K70 Ultra if you prioritize uncompromising performance, especially for demanding games and applications, and value the convenience of incredibly fast 120W charging. This phone is geared towards power users and mobile gamers.
