Frequently asked
Does the Poco C85 have a headphone jack?
Yes, it retains a 3.5mm headphone jack along with NFC and a side fingerprint sensor.
What is the screen resolution?
It uses a 6.9-inch LCD at HD+ (720p-class) with a 120Hz refresh rate.
Is the Redmi 15C 5G still supported?
Yes, with years to spare. It arrived in September 2025 running Android 15 with HyperOS 2, and Xiaomi's commitment carries security patches to around September 2031. In 2026 it is barely a fifth of the way through its window.
