Realme appears to be strengthening its C100 lineup with new devices, as fresh details about the Realme C100i and a new variant called the Realme C100x have surfaced online. The latest listings suggest that both smartphones could be launched soon in global markets, with the C100x also expected to debut in India.
The Realme C100i has recently been spotted on the Google Play Console, confirming several key specifications. Reports indicate that the device, carrying the model number RMX5377, will be powered by the Unisoc T615 processor along with 4GB of RAM. This setup suggests that the smartphone will support 4G connectivity instead of 5G.
In terms of display, the Realme C100i is expected to feature a resolution of 720 x 1570 pixels with a pixel density of around 320dpi. Previous leaks hint at a large 6.8-inch LCD panel offering brightness levels of up to 900 nits, making it suitable for outdoor usage. The device is also tipped to pack a massive 7000mAh battery while maintaining a slim profile of approximately 8.35mm thickness.
Additionally, the phone may come with durability enhancements, including a MIL-STD-810H certification for shock resistance and an IP64 rating for protection against dust and water exposure. Despite multiple global listings, the Realme C100i has not yet appeared on Indian certification platforms, leaving its India launch uncertain for now.
Meanwhile, another model, the Realme C100x, has also been making rounds online. The device, identified by the model number RMX5366, is expected to launch in India soon. It is likely to feature 4GB RAM and offer storage variants of 64GB and 128GB. Reports suggest that it could be available in attractive colour options such as Golden Coast and Deep Blue.
According to database listings in Europe, the Realme C100x could house a battery capacity of approximately 7,285mAh, which may be marketed as around 7,400mAh or higher. The battery is expected to retain up to 80 percent of its capacity even after extended charging cycles, ensuring long-term reliability.
The listing further reveals that the Realme C100x will feature an IP64 rating, along with strong endurance performance of over 90 hours. It also receives a high energy efficiency rating, along with decent durability and repairability scores, making it a balanced option in the budget smartphone segment.
