Frequently asked
Does the Poco C71 support 5G?
No. The Poco C71 is a 4G-only device powered by the Unisoc T7250.
What is the Poco C71's display like?
It has a large 6.88-inch HD+ IPS LCD with a smooth 120Hz refresh rate.
When will the Redmi 15C 4G stop getting security updates?
Under Xiaomi's expanded budget policy the Redmi 15C is set to receive four Android-based upgrades and around six years of security maintenance, so from its August 2025 launch it should be patched into 2031. It is already confirmed eligible for HyperOS 3 with Android 16 and future HyperOS 4. For a phone that often sells for barely over $100, that is an exceptionally long safe-to-use window.
Is the Redmi 15C 4G worth buying in 2026?
It is a sensible pick for anyone who needs the cheapest possible phone that will still be secure for years. The roughly $129 price across six supported years works out to under $2 a month, and the big battery, large screen and expandable storage cover the basics. The compromises are real, an HD+ LCD, 4G only and a slow chip, so it suits light users rather than anyone wanting speed or a sharp display.
