A new leak from 91mobiles suggests the Realme C100 5G will feature a 6.75-inch display and 5G support. The information surfaced on Thailand’s NBTC certification database today, showing a 4GB RAM configuration, the RMX5258 model number, and a “Sprouting Green” color option.
The Realme C100 Leaked Details
Here is exactly what the latest regulatory filings reveal about the Realme C100 5G. No fluff. Just the raw data from the official listings.
- Display Constraints: A large 6.75-inch panel. Crucially, the leak points to an older waterdrop-style notch rather than a modern hole-punch cutout.
- Internals: 4GB of RAM and 128GB of internal storage. A very classic, utilitarian budget configuration that signals an entry-level price point.
- Connectivity: Confirmed 5G support under the RMX5258 model designation.
- Aesthetics: The Realme C100 is officially listed as “Sprouting Green,” which aligns with the brand’s recent push toward vibrant, nature-inspired colorways.
- Design Focus: The chassis heavily prioritizes battery endurance and sheer screen size over premium touches like slim bezels or glass backs.
- Global Footprint: The Realme C100 cleared EU certification and briefly appeared on Amazon Italy. This proves we are looking at a wide global release, not a region-locked exclusive.
Compared to the Predecessor: Let’s look at the Realme C85 5G from late last year to see the real delta. The C85 dropped with a massive 6.8-inch display, up to 144Hz refresh rates, a rugged IP69 durability rating, and a gargantuan 7000mAh battery. The C85 also featured a robust MediaTek Dimensity 6300 processor.
The leaked specs for the Realme C100 5G indicate a noticeable pivot. You are seeing a slight screen reduction down to 6.75 inches. Using a waterdrop notch in 2026 feels completely regressive. You lose display real estate and step backward in design language. Given the 4GB RAM limitation on this new leak, we might be looking at a scaled-down chipset as well, possibly an entry-level Unisoc or a lower-tier MediaTek chip to balance the bill of materials.
While the battery size isn’t explicitly listed in the NBTC filing, the thick chassis design language implies they are chasing that same multi-day endurance crown. They are simply cutting corners on the display tech to keep the entry price low. It is a calculated trade-off.
Why so high? Regulatory databases do not lie. When a phone like the Realme C100 5G hits the NBTC and pops up on retail sites like Amazon Italy, the hardware is locked in. Production is already underway. 91mobiles has a solid track record with these specific certification spots. The accidental Amazon listing also tells us retail packaging and promotional materials are already being distributed to vendors.
My Take: I honestly think this is a highly confusing move by the brand. A waterdrop notch in 2026? Really? We just got away from those. It seems they are aggressively cutting costs on the display assembly to pack in a massive battery or to keep the retail price at absolute rock bottom.
I’ve seen this pattern before with entry-level tech lines. A company gives you the 5G badge so they can put it on the retail box, but they strip away the entire design budget to compensate. It is a classic misdirection. You get the fast network speeds, but you are staring at a screen that looks like it was manufactured three years ago. Running Android on 4GB of RAM in 2026 is also going to be tight. You will feel the lag if you try heavy multitasking.
If you compare this to rivals like the Moto G-series or Xiaomi’s budget 5G tier, the Realme C100 5G is going to look ancient on the shelf next to them. Motorola and Xiaomi are pushing sleek, punch-hole displays down to the sub-$150 tier. Realme is banking entirely on battery life and the 5G moniker to move units here. It feels like a device built specifically for fleet workers, delivery drivers, or anyone who needs a phone to stay alive for two days straight without caring about how it looks.
Conclusion
Should you wait for this launch? If you desperately need a cheap 5G signal and maximum battery life for basic daily tasks, maybe. This phone is a tool, not a toy. It will get the job done, but it won’t be pretty. The inclusion of 128GB of base storage is a nice touch, giving you plenty of room for apps and photos, but that alone doesn’t save the outdated front panel.
If you care about a modern media experience, watching videos, or gaming, I would absolutely skip it. Grab a discounted older model with a better screen instead.
