Redmi continues to build anticipation around its upcoming flagship, the K80 Ultra. After teasing the device’s design and chipset earlier, the company has now revealed additional hardware details focused on battery, charging, audio, and haptics.
According to the latest teaser shared on Weibo, the Redmi K80 Ultra features a massive 7410mAh battery. Xiaomi claims the device delivers up to 2.26 days of usage on a single charge based on its internal “Days of Use” (DOU) metric. The phone also uses microarchitecture-level tuning to reduce power consumption during extended use.
Redmi has also introduced a new Bypass Charging Plus system, which directs power separately to the motherboard and the battery. This design helps minimize heat generation, particularly during gaming. The K80 Ultra also becomes the first Redmi device to support 100W fast charging.
The device includes an upgraded CyberEngine haptic motor with ultra-wideband feedback and nearly 100 customized vibration patterns. Xiaomi claims this is the strongest and most refined haptic system on any Android phone. It uses a closed-loop driver chip for consistent tactile response across various use cases.
In terms of audio, the K80 Ultra features what Xiaomi calls “Master-Class Coaxial Symmetrical Dual Speakers.” Each speaker includes both tweeter and woofer units in a coaxial structure, supported by aerospace-grade domes and an ultra-smooth diaphragm. The setup is designed to deliver a broader frequency response, reaching up to 20kHz, and reportedly improves 8k–20kHz sound pressure levels by 16dB on average.
As confirmed earlier, the K80 Ultra is powered by MediaTek’s flagship Dimensity 9400+ chipset and Xiaomi’s in-house D2 discrete GPU. The device scored over 3.24 million points on AnTuTu V10. It also integrates the brand’s largest 3D IceLoop vapor chamber and uses Fury Engine 4.0 for deeper performance optimization.
Xiaomi is also preparing to launch the Redmi K Pad alongside the K80 Ultra later this month in China. The tablet features an 8.8-inch LCD panel with 3K resolution and a 165Hz refresh rate. It runs on the Dimensity 9400+ chipset, supports up to 16GB of RAM, and ships with Android 15. The device also includes 67W fast charging and a minimalist design with a single rear camera and LED flash. It is positioned to compete with the iPad Mini 7, Red Magic Gaming Tablet 3 Pro, and Lenovo Legion Y700 (Gen 4).
