Realme C100x Launched in India with Massive 8,000mAh Battery, 6.8-inch 120Hz Display: Price, Specifications

Realme introduced the Realme C100x in India on Thursday, the latest entry in its C-series lineup. It’s a budget phone built around two things: a massive 8,000mAh battery and a 6.8-inch display. Durability and battery life take priority here, not flashy extras. Realme hasn’t confirmed anything about a Nepal launch yet, but the spec sheet already gives local buyers a fair idea of what’s coming.

⚡ Highlights:
  • 6.8-inch 120Hz IPS LCD display
  • Unisoc T7250 chipset
  • 50MP AI dual rear camera
  • 8,000mAh battery with 45W fast charging

Display and Design

The Realme C100x comes with a 6.8-inch HD+ IPS LCD display, a 120Hz refresh rate, and around 254ppi pixel density. Scrolling and everyday use should feel noticeably smoother as a result. Touch sampling goes up to 240Hz, peak brightness hits 900 nits, and Panda MN228 glass protects the panel. There’s also a Rain Touch Mode on board. It’s built to keep the screen responsive even when fingers are wet or a little oily.

Design-wise, the phone ships in Deepblue Tides and Golden Coast colours and weighs 219 grams. Realme has clearly built this one to survive rough handling, with an ArmorShell chassis, MIL-STD-810H military-grade durability certification, and an IP64 rating for dust and splash resistance. Unlocking happens through a side-mounted fingerprint scanner. A small Pulse Light LED on the back flashes for notifications and charging status too.

Performance

The Realme C100x runs on an octa-core Unisoc T7250 processor with an Arm Mali-G57 GPU, plus 4GB of LPDDR4X RAM and 64GB of eMMC 5.1 storage. This is a 4G-only phone, so anyone wanting 5G should look elsewhere. Need more storage? Virtual RAM expansion and a microSD card up to 2TB can help. None of this is built for heavy gaming, but calling, browsing, and social media should run just fine.

The phone ships with Realme UI 7.0 on top of Android 16. Two features are worth calling out: AI Outdoor Mode automatically adjusts screen brightness and volume, while AI Netpilot works to stabilise the signal in weak network areas. Google Gemini and Circle to Search come pre-installed too, both just a long press of the power button away. That’s a nice touch for a phone in this price range.

Camera

On the camera front, the Realme C100x sticks to a single 50-megapixel rear sensor with an f/1.8 aperture, a 5P lens setup, and a 75-degree field of view. The AI-backed sensor handles exposure and colour adjustments on its own, so first-time smartphone photographers should be able to get decent shots without touching manual settings.

A 5-megapixel front camera with an f/2.2 aperture takes care of selfies and video calls. The camera app itself supports Portrait, Night, and Panorama modes, plus Dual-view video recording. It also throws in basic editing tools like an object eraser and Smart Image Matting, handy for quick touch-ups without leaving the phone.

Battery and Connectivity

The 8,000mAh battery is the real headline here. Realme claims it can handle more than 17 hours of continuous navigation on a single charge. Charging comes through a 45W fast charging setup, plus 6W reverse wired charging for topping up other devices. The company also says the battery should hold onto more than 80 percent of its original capacity even after seven years of regular use.

For connectivity, the dual-SIM C100x covers Bluetooth 5.2, GPS, GLONASS, BDS, and Galileo for navigation, plus Wi-Fi 5, a USB Type-C port, and a 3.5mm headphone jack. On the sensor side, there’s an accelerometer, an ambient light sensor, and an electronic compass. Security comes down to a side-mounted fingerprint scanner and face unlock.

Realme C100x Price and Availability in Nepal

In India, the Realme C100x is priced at INR 14,499 for the single 4GB RAM and 64GB storage variant. It’s available in Deepblue Tides and Golden Coast colours through Realme’s website, Flipkart, and select retail stores. Nepal doesn’t have an official price or launch date yet. It could land around NPR 26,000, though that figure stays unofficial until Realme confirms anything for the Nepali market.

Conclusion

The Realme C100x clearly bets on its massive battery and rugged build rather than raw performance. That fits its budget positioning well. Nepali buyers who care more about long battery backup and durability than top-tier speed might find this one appealing, but the Nepal launch is still unconfirmed. Until Realme makes it official, buyers here will just have to wait and watch.
