Chinese technology giant Xiaomi has once again proven its ability to surprise. It has just introduced its new flagship Redmi K80 Ultra (also referred to as Redmi K80 Extreme Edition) on the domestic market, which stands out primarily for its minimalist design, top-tier performance, and especially its massive battery, whose capacity exceeds the 7,000 mAh mark. Combined with an aggressive pricing strategy, it presents an interesting challenge even to significantly more expensive competitors.

Premium hardware led by MediaTek

Unlike some other flagship models of the brand, Redmi K80 Ultra relies on a chipset from MediaTek. Specifically, it’s the Dimensity 9400+, which can also be found in devices like OnePlus Ace 5 Ultra, Oppo Find X8s, or Vivo X200s. The phone is available with up to 16 GB of LPDDR5x memory and up to 1 TB of UFS 4.1 storage, which matches the specifications of flagship models.

In addition, it features a truly impressive 7410 mAh battery that supports 100W wired charging. As is typical for the Redmi series, wireless charging is unfortunately missing, which represents one of the compromises to keep the price favorable.

Premium display, but weaker cameras

Another significant advantage of the new model is its display. The 6.83-inch AMOLED panel offers a resolution of 2772 x 1280 pixels, a 144Hz refresh rate, and a peak brightness of up to 3,200 nits. Xiaomi also boasts the implementation of full DC dimming technology, which completely eliminates pulse-width modulation (PWM) and thus protects users’ eyes.

In terms of cameras, the Redmi K80 Ultra offers a 50Mpx main sensor and a 20Mpx front camera. However, the ultra-wide-angle lens with a resolution of 8 MP is rather below average compared to the competition, representing another area where costs were saved. There is no telephoto lens included in the rear camera setup at all.

It is therefore evident that Redmi definitely did not aim at photography enthusiasts and instead delivered a device that, in a minimalist package, offers fantastic performance and excellent battery life.

Aggressive price tag in China, potential arrival in the Czech Republic

The Redmi K80 Ultra starts in China at a price of 2,599 yuan (approximately 7,700 CZK excluding tax) for the version with 12 GB RAM and 256 GB storage. The most equipped variant with 16 GB RAM and 1 TB storage costs 3,799 yuan (about 11,200 CZK).

Regarding availability on the Czech market, it is likely that the phone could arrive here under the designation Xiaomi 15T Pro, which would correspond to the manufacturer’s current strategy. The previous generation Redmi K70 Ultra was sold globally as Xiaomi 14T Pro. However, it is necessary to consider that the global version may offer certain changes compared to the Chinese model, especially in the area of cameras, where there could be an improvement to the ultra-wide-angle camera and the addition of a telephoto lens. Typically, this could be the result of cooperation between Xiaomi and the German company Leica.
