Xiaomi Redmi K30 Ultra
- Excellent price-to-performance ratio
- Capable Dimensity 1000+ chipset
- Solid battery life
- Slower charging speeds
- Potentially less advanced camera system
Xiaomi Mi 10 Ultra
- Incredibly fast 120W wired charging
- 50W wireless charging
- Likely superior camera system
- Higher price point
- Snapdragon 865 may run hotter
Display Comparison
Both devices share an 'Infinite' (nominal) contrast ratio, suggesting excellent black levels typical of AMOLED panels. However, detailed display specifications like peak brightness and color gamut coverage are missing. Given the Mi 10 Ultra’s positioning as a premium device, it likely features a slightly more color-accurate display and potentially higher peak brightness for better outdoor visibility. The K30 Ultra, focusing on value, may have made compromises in this area. Without specific nit ratings, it's difficult to definitively declare a winner, but the Mi 10 Ultra likely has a slight edge.
Camera Comparison
The context data only states 'Photo / Video' for both devices, lacking crucial details like sensor size, megapixel count, and OIS. The Mi 10 Ultra, being the flagship, almost certainly features a more advanced camera system with a larger primary sensor and more sophisticated image processing. Xiaomi’s history suggests a focus on camera innovation in their ‘Ultra’ line. While the K30 Ultra likely offers a competent camera experience, the Mi 10 Ultra is expected to deliver superior image quality, especially in low-light conditions and with dynamic range. The absence of details prevents a precise comparison, but the Mi 10 Ultra is the likely winner based on brand positioning.
Performance
The core difference lies in the chipsets: the Redmi K30 Ultra utilizes the Mediatek Dimensity 1000+ (7nm) with an octa-core CPU configuration (4x2.6 GHz Cortex-A77 & 4x2.0 GHz Cortex-A55), while the Mi 10 Ultra boasts the Qualcomm Snapdragon 865 5G (7nm+), featuring an octa-core CPU (1x2.84 GHz Cortex-A77 & 3x2.42 GHz Cortex-A77 & 4x1.80 GHz Cortex-A55). The Snapdragon 865’s higher peak clock speed on its prime core and the more efficient 7nm+ node suggest a slight performance advantage in demanding tasks. However, the Dimensity 1000+ is a very capable chip, and real-world differences may be minimal for most users. Both devices likely utilize LPDDR5 RAM, but the speed isn't specified. Thermal management will be crucial; the Snapdragon 865 is known to run hotter, potentially leading to throttling under sustained load.
Battery Life
Both phones have an endurance rating of 85 hours, suggesting similar overall battery life despite the K30 Ultra’s unspecified battery capacity versus the Mi 10 Ultra’s. However, the charging speeds are drastically different. The K30 Ultra supports 33W wired charging, taking 58 minutes for a full charge. The Mi 10 Ultra, on the other hand, boasts 120W wired charging (41% in 5 minutes, 100% in 23 minutes), 50W wireless charging (100% in 40 minutes), and 10W reverse wireless charging. This makes the Mi 10 Ultra significantly more convenient for users who frequently need to top up their battery quickly. The faster wireless charging is a major advantage.
Buying Guide
Buy the Xiaomi Redmi K30 Ultra if you need a powerful daily driver with excellent performance for gaming and everyday tasks, without breaking the bank. It’s the ideal choice for users who value a balanced experience and aren’t willing to pay a premium for the absolute fastest charging or top-tier camera features. Buy the Xiaomi Mi 10 Ultra if you prioritize the fastest possible charging speeds, including 50W wireless, and demand a potentially superior camera system, even if it means a higher upfront cost.
