Realme is significantly expanding its budget lineup in India this year. Recent leaks indicate that a new model called the Realme C100x is in development for the Indian market. This device has the model number RMX5366. It appears the brand aims to offer a unique device, distinct from the global Realme C100 5G and C100i variants.
The company recently launched the Realme Narzo 100 Lite 5G in India on April 14, 2026. Now, they are shifting their focus back to the main C-series. Brands are competing to include the largest batteries in budget phones. The upcoming Realme C100x follows this trend as a true powerhouse. It seems like Realme is aiming at heavy users who prioritize screen time.
The Predecessor
To understand the new Realme C100x, we should look at the older Realme C80 series. The brand released the Realme C85 5G and Realme C85 Pro in November 2025. Those older models set a high standard for physical durability. They had IP68 and IP69K ratings along with MIL-STD-810H military-grade standards.
The C85 5G used the same MediaTek Dimensity 6300 chip but included 6GB of RAM. The C85 Pro went a step further with a faster Snapdragon 685 processor and a unique RGB notification light on the back.
Display and Design Trends
Leaked specs for the new Realme C100x show a large 6.8-inch LCD screen. It supports a fast 144Hz refresh rate for smooth scrolling, but only offers a basic HD+ resolution of 720×1570 pixels. This display choice is a noticeable downgrade compared to previous generations.
The older Realme C85 Pro provided a 6.8-inch AMOLED panel with Full HD+ resolution and a 120Hz refresh rate. You will likely see the lower pixel density on the new LCD screen. Realme seems to prioritize the high 144Hz refresh rate over image sharpness. Positioning it as a budget phone means the brand had to make some compromises.
Durability and Protection
Realme is changing its approach to phone durability this year. The older C85 series had top-tier IP68 and IP69K dust and water resistance. The new Realme C100x drops to a basic IP64 rating for dust and splashes, meaning it won’t survive a deep submersion in water like its predecessors.
Despite the lower IP rating, the brand still emphasizes physical toughness. Listings suggest the phone will have military-grade shock resistance to withstand daily drops. This feels like a strategic choice to keep the phone affordable. They are cutting back on expensive waterproofing while maintaining the drop protection that budget buyers need.
Battery and Charging Upgrades
Power is the main focus for this upcoming smartphone. Rumors suggest a huge 7,400mAh or 7,500mAh battery inside. This is an improvement from the 7,000mAh batteries found in the C85 5G and C85 Pro. You could easily get through two full days of heavy use.
Realme claims the battery will retain 80 percent of its health even after 1,600 charging cycles. That means it will last about four years of daily charging. It will also support 45W fast charging for that large battery. This feature is practical for users who dislike carrying power banks.
Performance and Camera Capabilities
Performance seems average for this price point. The phone uses the MediaTek Dimensity 6300 chipset to provide reliable 5G connectivity. The Realme C100x will only come with 4GB of RAM, with storage options of either 64GB or 128GB.
I find 4GB of RAM disappointing, especially since the older C85 5G offered 6GB. The lower memory may struggle with heavy multitasking in 2026. For photos, there’s a standard 50MP primary sensor and a basic 2MP depth lens. Selfies will be taken with a simple 5MP or 8MP front camera.
| Feature | Realme C100x | Realme C85 |
|---|---|---|
| Processor | Dimensity 6300 | Dimensity 6300 |
| Battery | 7,400mAh or 7,500mAh | 7,000mAh |
| Main Camera | 50MP + 2MP Depth | 50MP |
| Durability | IP64 (Shockproof) | IP68/IP69K (MIL-STD) |
Pricing Strategy and Market Value
Pricing leaks suggest the 4GB RAM and 64GB storage model will cost under Rs 13,000. The higher 128GB variant could be priced between Rs 13,500 and Rs 15,000. This pricing seems a bit high given the low RAM. You are effectively paying more for the large battery and 144Hz screen.
Buyers might consider the recently launched Realme Narzo 100 Lite 5G for better value. Selling a 4GB RAM phone for up to Rs 15,000 is challenging today. Realme seems to believe that the battery capacity will attract offline buyers.
This phone is designed for a very specific user. It targets buyers who work outdoors or travel often, with long battery life as the main feature. It is not suited for heavy mobile gamers or movie fans who need sharp visuals. I suggest waiting for real-world battery tests before making a purchase.
If you’re looking for a budget smartphone under Rs 15,000, the Realme C100x might be worth considering, especially if standby time is a priority. However, if you prefer a sharper screen, last year’s C85 Pro is a better option. Your ultimate choice in the budget power segment could very well be the Realme C100x.
