Key Highlights
- 6.75-inch HD+ LCD display with up to 120Hz refresh rate

Realme has launched the C100i 4G in India at ₹14,999, putting a large 6,500mAh battery and 120Hz display at the centre of its budget offering. While the phone skips 5G connectivity, it focuses on features that matter to buyers looking for long battery life and a smoother everyday experience.
The realme C100i 4G comes with a 6.75-inch HD+ LCD display, Unisoc T7250 chipset, 4GB RAM and 64GB storage. It also runs Android 16-based realme UI and supports 15W charging, while its IP64 rating and MIL-STD-810H shock resistance add extra durability.
At ₹14,999, however, the C100i enters a competitive segment where several rivals offer 5G connectivity and more capable cameras. That makes its large battery, 120Hz screen and durable build the main reasons to consider it.

Design & Build
The realme C100i uses a practical budget-phone design with a flat profile and a rear panel featuring realme’s Horizon Design. It is available in Midnight Black and Skyline Silver.
Durability is one of the more notable aspects of the phone. realme says the C100i has passed MIL-STD-810H military-grade shock-resistance tests and carries an IP64 rating for protection against dust and water spray. The company also highlights ArmorShell protection and a range of durability tests.
The handset includes a side-mounted fingerprint scanner, a USB Type-C port and a 3.5mm headphone jack.
Display
The realme C100i features a 6.75-inch HD+ LCD display with a resolution of 720 × 1,570 pixels and a refresh rate of up to 120Hz. It also supports up to 240Hz touch sampling and up to 900 nits of HBM brightness.
The 120Hz refresh rate should make scrolling through apps, websites and social media noticeably smoother than a standard 60Hz screen. The large panel should also work well for video consumption.
However, the display remains HD+ rather than Full HD+, so text and fine details will not look as sharp as they would on a higher-resolution panel of similar size. The LCD panel also does not offer the deeper blacks and contrast associated with AMOLED displays.
Performance
Powering the realme C100i is the Unisoc T7250, an octa-core chipset with two Cortex-A75 cores running at up to 1.8GHz and six Cortex-A55 cores clocked at up to 1.6GHz. Graphics are handled by an ARM Mali-G57 GPU.
The India model comes with 4GB of LPDDR4X RAM and 64GB of UFS 2.2 storage, with microSD expansion available. realme also advertises dynamic RAM expansion on the device.
This hardware is aimed at everyday tasks such as messaging, social media, web browsing and video streaming. The 120Hz display can make normal navigation feel smoother, but the T7250 is still an entry-level 4G chipset and should not be viewed as a gaming-focused processor.
There are no independent benchmark results included here, so gaming performance beyond the specifications should not be overstated.
Camera
For photography, the realme C100i has a single 8-megapixel rear camera with an f/2.0 aperture, autofocus and a 78-degree field of view. It supports up to 10x digital zoom and video recording at up to 1080p/30fps.
The front camera is a 5-megapixel f/2.2 sensor designed for selfies and video calls. It supports up to 720p/30fps video recording.
The camera setup is clearly focused on basic photography rather than versatility. There is no dedicated ultrawide or telephoto camera, so buyers who prioritise photography will find more capable alternatives around this price.
realme also provides software-based editing tools, including features such as AI Eraser and AI image enhancement on the device.
Battery & Charging
The India version of the realme C100i packs a 6,500mAh battery with support for 15W wired charging and reverse charging. realme says the battery is designed to retain more than 80 percent of its original capacity after five years under its stated testing conditions.
The large capacity is one of the phone’s strongest features and should appeal to users who spend long periods away from a charger. Reverse charging also allows the C100i to provide power to compatible accessories or another phone.
The main compromise is charging speed. At 15W, replenishing such a large battery will take considerably longer than on phones with faster charging systems.
It is worth noting that 7,000mAh is listed for some international versions of the C100i, but realme’s India product information confirms a 6,500mAh battery for the Indian model.
Software & AI
The realme C100i runs Android 16 with realme UI. The software includes practical features such as AI-based editing tools, AI NetPilot for network optimisation and one-press access to Gemini.
realme also promotes a three-year smooth-experience claim, although this should not be confused with a formal promise of three major Android version upgrades.
The software package is therefore more feature-rich than the basic hardware might suggest, although the actual experience will depend on how well the entry-level chipset handles heavier applications over time.
Connectivity & Special Features
The realme C100i is a 4G-only smartphone, with dual-SIM support, Wi-Fi 5, Bluetooth 5.2, GPS and USB Type-C connectivity. It also retains a 3.5mm headphone jack.
Other notable features include IP64 protection, MIL-STD-810H shock resistance, a side-mounted fingerprint scanner, reverse charging and stereo speakers.
There is no NFC support and no 5G connectivity.
Price & Availability
The realme C100i is priced at ₹14,999 in India for the sole 4GB RAM + 64GB storage configuration. It is available in Midnight Black and Skyline Silver.
The phone went on sale in India on August 27 through Flipkart, realme’s online store and mainline retail channels. Eligible students can receive a ₹250 coupon discount, while additional EMI offers are available through participating sales channels.
Competition & Alternatives
At ₹14,999, the realme C100i competes with several phones that prioritise performance or 5G connectivity over battery capacity.
| Alternative | Why Consider It? | Why Choose realme C100i Instead? |
|---|---|---|
| Lava Virat V1 5G | 5G connectivity and 13MP camera | Larger battery and 120Hz display |
| Lava Virat V1 Pro 5G | 5G, 50MP camera and 120Hz display | realme UI and 6,500mAh battery |
| realme C100x | Larger battery and faster charging in its positioning | C100i offers a lower-priced configuration |
The Lava Virat V1 5G is particularly relevant because it starts at ₹12,999 and offers 5G, a 6,000mAh battery and a 13MP rear camera. The newer Virat V1 Pro 5G also targets the same broad price segment with a 6,000mAh battery and 50MP camera.
This makes the C100i’s value proposition less about maximum specifications and more about its combination of battery capacity, 120Hz display, durability and realme’s software ecosystem.
Pros & Cons
Pros
- Large 6,500mAh battery
- 120Hz display
- IP64 protection
- MIL-STD-810H shock resistance
- UFS 2.2 storage
- Stereo speakers and 3.5mm headphone jack
- Android 16-based realme UI
Cons
- No 5G connectivity
- HD+ resolution on a large display
- Only 4GB RAM + 64GB storage in the India launch configuration
- 15W charging is relatively slow
- Basic 8MP rear camera
Final Verdict: Should You Buy It?
The realme C100i makes the most sense for buyers who prioritise battery life, a smooth 120Hz display and everyday durability over camera performance or 5G connectivity. Its 6,500mAh battery, IP64 rating and MIL-STD-810H shock resistance give it a practical advantage for users who want a phone built around endurance.
However, ₹14,999 is a competitive price point. Buyers who want 5G, a more powerful chipset or a significantly better camera can find stronger alternatives, including the Lava Virat V1 series.
Best for: Battery-focused users, students, casual smartphone users and buyers who value durability.
Consider alternatives if: You need 5G, stronger gaming performance or a more capable camera system.
Bottom line: The realme C100i is a straightforward endurance-focused 4G smartphone. Its 120Hz screen and large battery are compelling, but the lack of 5G and relatively basic camera hardware make it worth comparing with 5G alternatives before buying.
