Key Highlights

• Massive 8000mAh Battery
• 45W SUPERVOOC Fast Charging
• 6.8-inch 120Hz HD+ LCD Display
• Military-Grade Durability + IP64 Rating
• Starting Price: ₹14,499

Realme has expanded its budget C-series lineup with the launch of the Realme C100x, a smartphone that puts battery life ahead of everything else. Instead of chasing flagship-level specifications, the company has focused on what many budget buyers genuinely care about—long-lasting battery backup, a smooth display, dependable durability, and reliable everyday performance.

What immediately grabs attention is the massive 8000mAh battery, something rarely seen in smartphones priced under ₹15,000. Add to that a 120Hz display, 45W SUPERVOOC charging, military-grade durability, and Android 16, and the package starts looking quite appealing for users who spend long hours away from a charger.

Interestingly, Realme hasn’t positioned this phone as a gaming powerhouse or camera-centric device. Instead, it’s aimed at students, senior citizens, office users, delivery partners, travelers, and anyone who simply wants a smartphone that can comfortably last well beyond a full day on a single charge.

The Realme C100x follows a clean, minimal design that feels surprisingly premium for its price bracket. The flat frame, neatly integrated camera module, and subtle rear finish help it stand out from many entry-level smartphones that often look overly flashy.

The handset weighs 219 grams, which is expected considering the enormous battery packed inside. While it does feel slightly heavier than most budget phones, the weight is distributed fairly well, making it comfortable to hold during everyday use.

What stands out is Realme’s attention to durability. Along with an IP64 dust and water resistance rating, the phone also meets MIL-STD-810H military-grade durability standards, giving buyers extra confidence against accidental bumps and splashes. That’s actually impressive for a smartphone in this price segment.

Display

The Realme C100x features a 6.8-inch HD+ LCD display with a 120Hz refresh rate, making scrolling through social media, web pages, and the interface noticeably smoother than traditional 60Hz panels.

Brightness reaches 700 nits under normal conditions and up to 900 nits in High Brightness Mode, allowing the screen to remain reasonably visible outdoors. Although the display resolution stays at HD+, colours appear balanced, and the large screen offers an enjoyable viewing experience for YouTube, OTT streaming, and casual gaming.

Of course, users looking for a Full HD AMOLED display may find better alternatives in a slightly higher price bracket. However, considering the aggressive pricing, the overall viewing experience remains satisfactory for everyday entertainment.

Performance & Software

The Realme C100x is powered by the Unisoc T7250 chipset, paired with 4GB LPDDR4X RAM and 64GB eMMC 5.1 storage. The processor is built on a 6nm process and comes with an octa-core CPU setup designed mainly for regular smartphone tasks rather than heavy performance.

During everyday usage, the handset handles basic activities comfortably. Apps like WhatsApp, Instagram, YouTube, Chrome, and banking applications run smoothly, especially when users are not pushing too many heavy apps simultaneously.

The 120Hz refresh rate helps the overall experience feel more responsive while scrolling and navigating through menus. Interestingly, this is one area where Realme has balanced the hardware nicely—the display feels smoother than what many users expect from a budget smartphone.

For gaming, the device is suitable for casual players. Lightweight games run without issues, while popular titles like BGMI or Call of Duty Mobile may require lower graphics settings for a stable experience. This smartphone is clearly designed more for battery-focused users rather than gamers who want maximum FPS performance.

On the software side, the phone runs Android 16 with Realme UI, bringing modern features, customization options, and improved privacy controls.

Camera Performance

The Realme C100x comes with a single 50MP rear camera with an f/1.8 aperture and autofocus support. On the front, there is a 5MP selfie camera for video calls and casual selfies.

In daylight conditions, the main camera can capture decent images with good details when lighting is favorable. Social media users should find the colours attractive, as Realme’s processing generally prefers slightly enhanced tones rather than completely natural-looking photos.

Interestingly, the 50MP sensor gives users enough flexibility for casual photography, but this is not a camera phone aimed at photography enthusiasts. Dynamic range can struggle in challenging lighting situations, and low-light shots may show visible noise.

Portrait shots are acceptable for the price, while the 5MP selfie camera works well for video calls and occasional selfies. For Instagram stories, WhatsApp calls, and daily memories, the camera setup gets the job done.

Video recording support includes Full HD recording at 30fps, along with slow-motion features.

Battery & Charging

The biggest highlight of the Realme C100x is undoubtedly its 8000mAh battery.

This is a massive capacity for a budget smartphone and is designed for users who don’t want to carry a charger everywhere. With moderate usage, including social media, browsing, video streaming, and calling, the phone can easily stretch beyond a full day.

For lighter users, the battery backup can potentially reach multiple days on a single charge. Realme has also included 45W SUPERVOOC fast charging, which helps reduce the waiting time despite the huge battery size.

Honestly, this battery-focused approach makes the C100x attractive for travellers, students, and users who spend long hours outdoors.

The only trade-off is that the larger battery also adds weight. At around 219 grams, the phone feels heavier compared to regular budget smartphones, but that is expected with an 8000mAh cell.

Storage & Connectivity

The device comes with:

• 64GB internal storage
• eMMC 5.1 storage technology
• Expandable storage support
• Dual SIM support
• 4G connectivity
• Wi-Fi 5
• Bluetooth 5.2
• USB Type-C port
• 3.5mm headphone jack

The absence of 5G connectivity may disappoint some buyers looking for future-ready network support. However, users who mainly need calling, streaming, browsing, and social media will find the connectivity package sufficient.

The inclusion of expandable storage is a useful addition because the base 64GB storage can feel limited after installing multiple apps and downloading media files.

Final Verdict: Should You Buy Realme C100x?

The Realme C100x is a smartphone built around one clear idea—maximum battery life.

It does not try to compete with performance-focused phones or camera-centric devices. Instead, it offers an extremely large battery, smooth 120Hz display, durable design, and reliable everyday performance at an affordable price.

For users who prioritize battery backup above everything else, this phone makes a lot of sense. Students, travellers, delivery professionals, and users who frequently forget charging will appreciate what the handset offers.

However, buyers looking for 5G connectivity, stronger gaming performance, or a sharper display should compare other options in the same price range.

At ₹14,499, the Realme C100x is a practical budget smartphone with a unique selling point. If your priority is “charge less, use more,” this device is one of the interesting choices in its segment.
