Realme is expanding the C100 lineup with two new models that have now started to surface in certification databases and leak channels. The Realme C100i and Realme C100x appear to continue the brand’s push in the entry-level segment, where long battery life, basic performance, and durability matter more than premium features.
The new information suggests that Realme wants to turn the C100 series into a more complete family after introducing the Realme C100 5G in Thailand. Recent filings point to devices that are built for daily use, with one model leaning toward 4G value buyers and the other aimed at a larger market such as India.
Realme C100i appears in certification lists
The Realme C100i has been spotted with model number RMX5377 on NBTC and Google Play Console. Devices that appear on both platforms are usually close to launch, which makes the C100i one of the clearer signs that Realme’s next entry-level phone is moving toward release.
Leaked specs indicate that the phone uses the Unisoc T615 chipset and 4GB of RAM. That combination points to a 4G-only device that should be focused on everyday tasks, light apps, and power efficiency rather than high-end gaming or advanced connectivity.
The display is also starting to take shape through the leaks. Reports mention a 6.8-inch LCD panel with 720 x 1,570-pixel resolution and 320 dpi density, while another leak points to peak brightness of up to 900 nits.
A huge battery is the main attraction
One of the biggest talking points around the Realme C100i is its 7,000mAh battery. That capacity places the phone in the group of devices designed for long uptime, especially for users who need a handset that can last through work, streaming, messaging, and social media without frequent charging.
The phone is also said to measure around 8.35 mm thick despite the large battery. If this figure holds up, Realme may offer a more balanced design than many battery-focused phones that usually feel bulky.
Durability seems to be part of the plan as well. Some leaks mention MIL-STD-810H certification and an IP64 rating, which would help the C100i stand out in the affordable segment with some level of resistance to dust and water splashes.
Realme C100x targets India with larger storage options
Alongside the C100i, Realme is also preparing the C100x, which carries model number RMX5366. This model is expected to launch in India and has been linked to 4GB of RAM with 64GB and 128GB storage options.
The C100x also appears in two color options, Golden Coast and Deepblue Tides. That detail suggests Realme still wants an attractive design identity even in a low-cost phone.
According to EPREL data, the battery capacity is listed at around 7,285mAh. In retail branding, that figure may be rounded up and marketed as 7,400mAh or 7,500mAh, which is common practice in the smartphone industry.

What Realme is signaling with the C100 series
The leaks suggest Realme is building the C100 line around a simple formula: big batteries, modest hardware, and stronger durability for budget users. That strategy fits a segment where many buyers want a phone that lasts all day, handles basic needs reliably, and costs less than mid-range alternatives.
The C100x may also include a stated battery life of more than 90 hours and an A energy efficiency rating based on EPREL data. If those details are confirmed at launch, the model could become a solid option for buyers who value endurance more than headline specifications.
Realme has not announced an official launch date for the C100i or C100x yet, but their appearance in certification databases usually means the release window is getting closer. For now, the growing number of listings and leaks shows that the Realme C100 series is becoming more complete, with two new models prepared to strengthen the brand’s entry-level presence.
