Overview of the Xiaomi Redmi 15C 4G
The Xiaomi Redmi 15C 4G, which we have recently examined, navigates this challenge quite effectively. For just above $100, users receive a substantial battery, a reasonably bright display without PWM flicker, and a commendable update commitment.
Battery Performance and Charging
Diving deeper into our findings, during our real-life Wi-Fi assessment, the Redmi 15C 4G lasted just shy of 21 hours. This duration is sufficient for multiple days of usage without needing to recharge, making it great for those who enjoy binge-watching shows or films. In case of emergencies, its 33-watt charging capability is also quite impressive.
The extended battery life is attributed to a 6,000 mAh power source, which is uncommon for phones in this price range. Thanks to innovations in battery technology, this device isn’t heavier than other models with smaller batteries.
Features and Build Quality
If having a 3.5 mm audio jack is important to you, rest assured, it is included. There’s also NFC support for mobile payments and an ID app, plus a fingerprint sensor for quick unlocking. We were pleasantly surprised by the promise of six years of updates. It will be interesting to see if this commitment holds true for such a budget-friendly device.
As indicated by its name, this economical smartphone does not support 5G. Xiaomi also had to make some compromises with the body design. While it features an eye-catching back cover with a shimmering wave pattern, the overall build quality is quite average. The camera performance and audio quality are also not top-notch.
