Realme C100x India Launch: 4GB RAM, 7000mAh Battery & Colours Leaked

Here’s a good news for budget friendly phone seekers: Realme C100x (RMX5366) is coming to India with 4GB+64GB/128GB variants, Golden Coast and Deepblue Tides colours. Here are the latest leaks on its 6.8-inch 144Hz display, Dimensity 6300, 50MP camera and massive 7000mAh battery.

They just launched the C100 5G and C100i in Thailand a few days ago. Now, fresh leaks point to a new model headed for India — the Realme C100x.

Realme C100x: A Fresh Budget Option

Realme keeps growing its C-series to reach more people who want their first 5G phone. The C100x carries model number RMX5366. It looks like an even cheaper version than the new C100 5G.

Leaks shared by sources like 91mobiles just yesterday show the phone will come in two simple variants: 4GB RAM + 64GB storage and 4GB RAM + 128GB storage. You’ll probably be able to expand storage with a microSD card, just like other models in the series.

The colors sound nice and lively. You can pick between Golden Coast — a warm, sunny shade — and Deepblue Tides, a calm ocean blue. These options suggest Realme wants the phone to look good without pushing the price higher.

The C100x sits at the entry level of the C100 lineup. It targets students, first-time users, or anyone who mainly needs the phone for calls, WhatsApp, YouTube, and light daily use.

What the C100x Is Likely to Offer

Early leaks give us a good idea of what’s inside.

You should get a big 6.8-inch LCD screen with HD+ resolution and a smooth 144Hz refresh rate. That makes scrolling and watching videos feel nice and fluid. The screen should stay bright enough for outdoor use too.

Power comes from the MediaTek Dimensity 6300 chipset. This processor handles everyday tasks well and supports 5G. With 4GB of RAM, it should manage basic multitasking without much trouble.

For cameras, expect a 50MP main rear camera with LED flash. It should take decent photos in good light. Up front, there’s a 5MP selfie camera for video calls and quick snaps.

The real highlight is the battery. The C100x is expected to pack a huge 7000mAh cell. That means you can easily get one and a half to two days of use on a single charge. Charging will likely be modest, around 15W or 18W.

Other handy features include a side-mounted fingerprint sensor, IP64 dust and splash resistance, a 3.5mm headphone jack, USB-C port, and dual SIM with 5G support.

The phone should run Android 16 with Realme’s user-friendly interface on top. It will have a plastic body, which keeps the weight light — around 210 to 212 grams.

Here’s a quick look at the expected specs:

Keep in mind these details are from leaks, so small changes could still happen before launch.

How the C100x Fits with Its Siblings

Realme quietly launched the C100 5G and C100i in Thailand on April 3, 2026. Both share the same large 6.8-inch screen and massive 7000mAh battery. The 5G version uses the Dimensity 6300 and offers higher RAM options in some markets. It goes on sale there around April 22.

The C100i is the 4G-only model with a simpler build. Prices in Thailand start low — roughly equal to Rs 17,000 or less.

The C100x seems aimed even lower for the Indian market. With just 4GB RAM and 64GB base storage, it could launch under Rs 10,000 or in the early Rs 10,000–12,000 range. That would make it one of Realme’s most affordable 5G phones yet.

Compared to the C85 5G (which starts around Rs 14,999), the C100x trades some speed and RAM for a bigger battery and smoother screen at a likely lower price.

Why This Could Matter to You in India

If you’re shopping in India, the C100x might be a solid choice for entry-level 5G. Many people still look for their first 5G phone or a simple device for parents or kids. The huge battery means less worry about running out of power during long days or power cuts.

The 144Hz display will make scrolling social media or watching short videos feel smoother than on older phones. The 50MP camera should handle everyday shots well enough for sharing on WhatsApp or Instagram.

Realme has built a strong name for delivering good value in budget phones. The C-series focuses on the basics done right. You get reliable performance without paying for extras you may never use.

We still need official word on exact pricing, charging speed, and real-world camera performance. But the leaks paint a clear picture of a simple, long-lasting phone.

End Note

Realme hasn’t announced a launch date for the C100x yet. Since the storage and color details appeared so quickly, we could see an official reveal in the coming weeks.

Keep an eye on Realme’s India website, Flipkart, and Amazon. Sites like 91mobiles and GSMArena will update the full specs and price as soon as they drop.

If long battery life and smooth daily use top your list, the C100x looks like one to watch. It builds nicely on the C100 series while keeping the price as low as possible.

You can compare it later with other budget 5G options from Redmi, Poco, or Moto. For now, the mix of a 7000mAh battery, 144Hz screen, and 5G support makes it interesting.
