About product
The realme C100x is an entry-level, budget-focused 4G Android smartphone launched mid-2026. It stands out primarily for its exceptionally massive battery capacity and ruggedized, durable design tailored for long-lasting use.
Below is the comprehensive, technical description and specification breakdown of the device:
Battery & Charging
The definitive highlight of the realme C100x is its heavy-duty power system:
Battery Capacity: 8,000 mAh silicon-carbon battery, offering up to 3 days of light use or over 21 hours of continuous benchmark performance.
Charging: 45W SUPERVOOC fast charging (takes roughly two hours to charge fully).
Bonus Features: Supports Power Delivery (PD), Programmable Power Supply (PPS), and reverse wired charging to charge secondary electronics.
Design & Rugged Durability
Despite its budget placement, the device is heavily reinforced to withstand everyday wear and tear:
Durability Certifications: MIL-STD-810H military compliance for shock resistance, paired with realme’s proprietary ArmorShell protection.
Water & Dust Protection: IP64 rating (resistant to heavy dust and water splashes).
Build Quality: Features a drop-resistant case, reinforced corners, and a unique 9-color RGB pulse/notification light on the back panel.
Dimensions & Weight: 166.5 × 78.2 × 8.6 mm; weighs 219 grams due to the massive battery cell.
Display
Screen Size: 6.8-inch IPS LCD panel.
Refresh Rate: 120Hz Ultra Smooth Display for smooth UI navigation and scrolling.
Resolution: HD+ (720 × 1570 pixels), sitting at approximately 254 PPI density.
Brightness: Reaches a peak brightness of 900 nits, allowing for solid outdoor legibility.
Performance & Hardware
The phone trades 5G connectivity for a highly functional, everyday budget chipset.
Processor: Unisoc T7250 (12nm architecture) octa-core processor.
Graphics: ARM Mali-G57 GPU.
Camera Setup
The camera architecture focuses on a high-resolution primary lens rather than filling the back with low-quality auxiliary sensors.
Rear Camera: 50MP AI Main Camera (f/1.8 or f/2.0 aperture) featuring autofocus, accompanied by a decorative auxiliary sensor. Video recording caps at 1080p @ 30fps.
Front Camera: 5MP sensor (f/2.2 aperture) housed inside a waterdrop notch for casual selfies and video calling.
Connectivity, Software & Audio
Operating System: Ships with Android 16 configured via the realme UI overlay skin.
Network limitations: 4G LTE only (No 5G support).
Sensors: Side-mounted fingerprint reader, Accelerometer, Proximity sensor, Compass, and Ambient light sensor.
