Overview & Key Details
The Xiaomi Poco C81x marks a definitive entry standard in the Ultra-Budget Smartphone landscape, prioritizing expansive display area and lasting battery efficiency. Driven by an energy-conserving 12nm Unisoc T7250 processor paired with 3GB of LPDDR4X RAM and 64GB of built-in storage (expandable up to 2TB via a dedicated MicroSD slot), it maintains a streamlined routine running on Android 15-based Xiaomi HyperOS 3. The front is highlighted by a massive 6.88-inch 120Hz HD+ IPS LCD display that delivers rare scrolling smoothness for a sub-budget phone alongside a peak high-brightness mode of 650 nits. Encased in a lightweight 193g chassis with basic IP52 dust and splash resistance, it packs a dependable 5,200mAh battery with 15W wired charging, 7.5W reverse wired power routing, a single 13MP primary camera, and an essential side-mounted fingerprint security lock.
