Redmi K100 is a gaming powerhouse with a huge battery. It costs under 10,000 CZK

Xiaomi introduced the Redmi K100 in China, which, several months later, complements the more expensive K100 Pro and K100 Pro Max models. It aims to attract primarily gamers who seek solid performance for relatively little money and care about battery life. The new basic model offers a capacity of 10,000mAh and, in addition to the classic chipset, also features a second chip designed to add fluidity to games while saving energy.

Older flagship processor complemented by D2 gaming chip

The phone is powered by the Snapdragon 8 Elite, which Qualcomm introduced back in 2024. The more expensive Pro Max received the newer Gen 5. However, even the older chip has plenty of power to spare: its two most powerful cores run at 4.32 GHz and are complemented by up to 16 GB of LPDDR5X RAM and fast UFS 4.1 storage.

According to Xiaomi, this is the first basic model in the K series to feature a dedicated D2 gaming chip. In games, it interpolates frames and enhances image resolution. The manufacturer states on its website that in a popular team strategy game (MOBA) at 144 fps, it reduces average power consumption by 22% and peak temperature by 3.9 °C. Furthermore, according to the manufacturer, the cooling system has a quarter larger surface area than its predecessor.

165 Hz display utilized by over 40 games

The front features a 6.83-inch AMOLED display with a resolution of 2772 × 1280 pixels and a refresh rate of up to 165 Hz. According to Xiaomi, over 40 games can natively handle a full 165 fps, and another hundred will achieve it thanks to the D2 chip. However, some titles will only receive the new frequency with an update, which the manufacturer promises by the end of November at the latest.

It shines with a brightness of up to 3,500 nits over a quarter of its area, while at night, you can dim it down to 1 nit. The display is designed to protect eyes with flicker-free dimming across the entire brightness range.

10,000 mAh battery lasts over two days, according to Xiaomi

The silicon-carbon battery has a capacity of 10,000 mAh, just like the Redmi Note 17 Pro Max we tested. Xiaomi promises that with typical use, it will last 2.43 days, which the company claims is the longest battery life of all its mobile phones.

It charges via cable with 100 W power, and the charger is included in the package. Additionally, via USB-C, it can charge headphones or another phone with up to 27 W of power. Wireless charging, however, is completely absent.

Phone weighs over 230 grams and lacks a telephoto lens

The large battery is noticeable in its weight. The phone weighs 234.5 grams and measures 8.65 mm in thickness. On the back, you’ll find only two cameras: a 50Mpx main sensor with optical stabilization and an 8Mpx ultrawide. A telephoto lens is absent; 2x zoom is provided by the main sensor.

The rest of the features are consistent with more expensive phones. The Redmi K100 is resistant to water and dust according to IP66, IP68, IP69, and IP69K standards, unlocks with an ultrasonic in-display fingerprint reader, and the stereo speaker sound was tuned by Bose. It also includes Wi-Fi 7, NFC, and an infrared port, and runs on HyperOS 4 out of the box.

Xiaomi has not yet spoken about a European launch. The more expensive K100 Pro and Pro Max are the basis for POCO F9 Pro and F9 Ultra, which have been sold in the Czech Republic since September. A European version of the basic model has not yet been announced.

Would an older flagship chip be enough for gaming if it’s complemented by a two-day battery?
