Realme C100 Specifications
The Realme C100 5G is built for speed and long-lasting power. It runs on a MediaTek Dimensity 6300 chip with 5G support, meaning faster downloads and smoother streaming if you are on a next-gen network. The 6.8-inch IPS LCD screen is buttery smooth thanks to a 144Hz refresh rate, and it gets bright enough (up to 900 nits) to use outdoors. Under the hood, you get either 4GB or 6GB of RAM with 128GB of storage, plus a massive 7,000 mAh battery that supports 45W fast charging. The main camera is a solid 50MP shooter, and the phone comes with a side fingerprint sensor, stereo speakers, and a headphone jack. It also has basic IP64 water resistance, so it can handle splashes but not a swim. Available in Purple or Green, it is priced at around $190 (Rs 17,990 in India) approximately.
Now, the Realme C100 4G takes a completely different approach; it is a rugged beast. Instead of 5G, it focuses on durability with an IP66/IP68/IP69K rating, meaning it is dust-tight, survives high-pressure water jets, and can be submerged up to 6 meters for 30 minutes. It is also drop-proof from up to 2 meters. The screen is a 6.8-inch 120Hz display but cranked to 1,200 nits for extra brightness outdoors, protected by tougher ArmorShell Glass. Inside, it uses a Helio G92 Max chip, paired with a generous 8GB RAM and 256GB storage. The battery is even larger at 8,000 mAh, though charging is slower at 15W. It also upgrades the selfie camera to 8MP and includes NFC (market dependent). Expect to pay around $170 (Rs 15,990 in India) approximately for this one, available in White, Purple, or Brown.
So, which one should you pick? If you want faster screen refresh rates, 5G connectivity, and speedier charging, go with the Realme C100 5G. But if you work outdoors, drop your phone often, or need something that can survive rain, dust, or even a dunk in water, the Realme C100 4G is the clear winner. It trades 5G and charging speed for serious armor and an even bigger battery. Both run Android 16 with Realme UI 7.0, keep the headphone jack, and pack stereo speakers, so everyday use feels modern and fun.

Realme C100 Pros and Cons
Based on the above specs, you can see the list of pros and cons (advantages and disadvantages) of the Realme C100 Smartphone.
Pros
- The 4G version packs a massive 8000 mAh battery, while the 5G version has a 7000 mAh battery. Both phones easily last a full day or even two days of heavy use without needing to charge.
- The 4G model features IP66/IP68/IP69K dust and water resistance, making it fully waterproof up to 6 meters and resistant to high-pressure water jets. This is extremely rare for a phone at this price.
- Both phones have a 144Hz (5G) or 120Hz (4G) high refresh rate display. This makes scrolling through social media and playing games feel very smooth and responsive.
- The 4G version includes 256GB storage and 8GB RAM out of the box, which is double the storage of the 5G model.
- The 5G model supports 45W fast charging and reverse charging.
Cons
- Both models only have a 720p screen resolution on a large 6.8-inch display. This makes text and images look less sharp compared to phones with 1080p screens at this price range.
- The 5G version has a weak 5MP selfie camera, and the 4G version has only an 8MP one. Neither takes good quality selfies, especially in low light or indoors.
- The durable 4G model only supports 15W charging, which is very slow for an 8000 mAh battery and will take over 3 hours to fully charge.
- The 5G model has no NFC, so you cannot use Google Pay or tap-to-pay features.
- Realme C100 5G only has basic IP64 splash resistance, so it is not safe to submerge it in water.
