Xiaomi Redmi 15C is a budget Android phone that leans hard into the basics: a giant 6.9-inch display, a massive 6,000 mAh battery with faster 33 W charging, IP64 splash resistance, and a now-brighter screen. Compared to the Redmi 14C, the Redmi 15C retains the frugal Helio G81 Ultra but enhances day-to-day comfort with increased brightness, a larger battery, and quicker top-ups, offering functional upgrades you’ll actually feel. Do note: the selfie camera steps down to 8 MP from the 14C’s 13 MP.

Design
Xiaomi Redmi 15C sticks to a clean, grippy polycarbonate build offered in Midnight Black, Moonlight Blue, Mint Green, and Twilight Orange.
It’s slightly thinner than its predecessor (7.99 mm vs. 8.22 mm), with a side-mounted fingerprint scanner, a 3.5 mm headphone jack, and a practical IP64 rating for dust and water splash resistance, which brings a welcome peace of mind.
Display
You get a big 6.9-inch HD+ (1600×720) IPS “tear Drop” panel that now reaches 660 nits typical and 810 nits HBM, plus up to 120 Hz refresh rate and 240 Hz touch sampling.
That’s a meaningful bump over the 14C’s brightness (450/600 nits), so outdoor readability improves, while the high refresh keeps scrolling snappy. TÜV Low Blue Light, Circadian-friendly, and flicker-free certifications are on board.
Camera
On the rear is a 50-megapixel main camera (f/1.8, 5P lens) with Night mode, HDR, and 1080p/30fps video. A QVGA sensor is also provided on the back to support the main camera.
Up front, the Xiaomi Redmi 15C features an 8-megapixel selfie camera with HDR, Night mode, and 1080p video recording. Versus the Redmi 14C, the primary camera spec is similar, but the 14C’s selfie camera is higher at 13 MP, worth noting if you prioritize selfies.
Hardware and Software
Under the hood, the Xiaomi Redmi 15C features the MediaTek Helio G81-Ultra with Mali-G52 MC2 graphics, paired with LPDDR4X RAM and eMMC 5.1 storage in several configurations starting at 4 GB / 128 GB (up to 8 GB/256 GB), plus microSD expansion up to 1 TB.
Out of the box, it runs Xiaomi HyperOS 2 based on Android 15. However, Xiaomi is not committing to multi-year major Android upgrades and security updates, unlike Samsung with the Galaxy A07. It’s not a gaming chip, but it handles social, school, light gaming, and streaming without fuss.
Perhaps the 6,000 mAh battery with 33W fast charging via USB Type-C is the headline feature of this Android phone. That’s a notable leap from the 14C’s 5,160 mAh/18 W, delivering longer endurance and much quicker top-ups, ideal for long days without power.
Connectivity
Xiaomi Redmi 15C features Dual-SIM 4G LTE, dual-band Wi-Fi (2.4/5 GHz), Bluetooth 5.4 (AAC/SBC/LDAC), FM radio (headset required), GPS/GLONASS/Galileo/BeiDou, and a 3.5 mm audio jack. NFC is region-dependent; check local units if you need them for payments. Side fingerprint and AI face unlock are supported.
If your priorities are battery life, fast charging, and a huge screen on a tight budget, the Redmi 15C is easy to recommend. It outperforms many peers in endurance (6,000 mAh) and charging speed (33 W), while also adding IP64 and dual-band Wi-Fi, and retaining essentials like microSD and headphone jack.
