Realme has launched the C100x in India, and this one is clearly built for people who want battery backup more than anything else. The phone comes with a massive 8,000mAh Titan Battery, 45W fast charging and a starting offer price of Rs. 14,499.
This is not a premium gaming phone or a camera-heavy flagship. It is a practical budget phone for users who spend long hours outside, watch videos, attend online classes, use hotspot, travel often or simply do not want to keep looking for a charger.
The Realme C100x 4G is available from July 16, 2026, through mainline stores, Flipkart and Realme’s official website. Yesterday, Realme launched Narzo 100X with 8000mAh battery.
Realme C100x price in India
The Realme C100x 4G is priced at Rs. 14,999 for the 4GB RAM and 64GB storage variant.
Realme is offering a Rs. 500 launch offer, bringing the effective price down to Rs. 14,499. The first sale offer is available from July 16 to July 20, 2026.
At this price, Realme is targeting buyers who want a long-lasting phone with decent everyday performance, not those looking for top-end gaming power.
Biggest highlight – 8,000mAh Titan Battery
The main reason to notice the Realme C100x is its 8,000mAh battery. Most budget phones still offer around 5,000mAh or 6,000mAh batteries, so this is a big jump.
For regular users, this can mean two-day battery life or even more with light use. For heavy users, it should still last much longer than a normal budget phone.
The phone supports 45W SuperVOOC fast charging. That matters because a large battery can become annoying if it takes too long to charge. It also supports reverse wired charging, so it can help charge smaller devices like earbuds or another phone in an emergency.
Display and design
The Realme C100x gets a 6.8-inch HD+ IPS LCD display with 720 x 1570 pixel resolution.
It supports a 120Hz refresh rate, which should make scrolling and app movement feel smoother. Brightness goes up to 700 nits typical and 900 nits in high brightness mode.
The display is protected by Panda MN228 glass. The resolution is not Full HD+, so users who watch a lot of high-quality video may notice that sharper screens exist in this segment. But the lower resolution may also help stretch battery life further.
Performance and software
The phone is powered by the UNISOC T7250 processor, paired with Mali-G57 MP1 GPU.
This is an entry-level 4G chipset, so expectations should be realistic. It should handle WhatsApp, YouTube, Instagram, browsing, calling, payments, light games and online classes without much trouble.
But if you play heavy games at high graphics settings, this is not the phone for that. The Realme C100x is made more for battery life and durability than raw performance.
It runs Android 17 with Realme UI 7.0. Storage is 64GB eMMC 5.1, and it can be expanded up to 2TB using a microSD card.
Camera setup
The Realme C100x has a 50MP rear camera with f/1.8 aperture and LED flash. On the front, it gets a 5MP selfie camera.
The rear camera should be useful for daylight photos, documents, casual portraits and social media shots. The front camera is basic, so selfie lovers should check samples before buying.
At this price, Realme is clearly selling battery and toughness first. Camera is useful, but not the main story.
Durability and build
Realme has added ArmorShell Protection to the C100x. The phone has MIL-STD-810H military-grade certification for shock resistance.
It also gets an IP64 rating for dust and splash resistance. That means it can handle dust and light splashes better than a regular phone, but it is not waterproof.
The phone weighs 219g and measures 8.8mm thick. That weight is expected because of the huge battery. If you prefer slim and light phones, this may feel a bit heavy.
Connectivity and other features
The Realme C100x supports dual 4G VoLTE, Wi-Fi 802.11 ac, Bluetooth 5.2, GPS, GLONASS, Galileo, QZSS and USB Type-C.
It also keeps the 3.5mm headphone jack, which many budget users still like. For security, there is a side-mounted fingerprint scanner.
The phone has an ultra-linear bottom-ported speaker, which should be fine for calls, videos and casual music listening.
Realme C100x competitors
The Realme C100x will compete with budget phones from Redmi, Poco, Motorola, Samsung, Lava and Infinix.
Its strongest point is the 8,000mAh battery. Some rivals may offer 5G, Full HD+ displays or stronger processors, but not many will match this battery size at this price.
So the choice is simple. If you want 5G or better performance, look elsewhere. If you want long backup and a tough daily phone, the C100x becomes interesting.
Should you buy Realme C100x
Buy the Realme C100x if battery life is your top priority. It is also a good option for students, field workers, travellers, delivery partners and people who use their phone heavily through the day.
Skip it if you want 5G, a sharper Full HD+ display, strong gaming performance or a premium selfie camera.
Conclusion – Key takeaways
The Realme C100x is a battery-first budget phone. Its 8,000mAh Titan Battery, 45W charging, reverse charging, 120Hz display, 50MP rear camera and rugged build make it a practical option under Rs. 15,000.
It is not trying to beat performance phones. It is trying to solve a simpler problem – keeping your phone alive for longer.
For buyers who want a dependable 4G phone with excellent battery backup, the Realme C100x is worth checking.
