realme C100X - Price in India, Features and Specs

The C100X features a large 6.78-inch IPS LCD screen with a 120Hz refresh rate, making scrolling, gaming, and video watching feel smooth and lag-free. The punch-hole design keeps bezels minimal, giving users more screen to work with. At 259 PPI, text and images look reasonably sharp for everyday use.

The realme C100X runs on an octa-core processor paired with 6GB RAM and up to 6GB of extended virtual RAM, giving users up to 12GB of effective RAM for smoother multitasking. This means switching between multiple apps, browsing, and streaming can all happen without the phone slowing down noticeably.

128GB of onboard storage gives users ample room for apps, photos, and media. The hybrid SIM slot also supports a microSD card for users who need extra space, though using it means giving up the second SIM slot.

The C100X keeps photography simple and capable with a 50MP wide-angle rear camera that handles everyday shots well, backed by a 2MP depth sensor for portrait photos with background blur. The 16MP front camera is a strong performer for a budget phone, delivering clear selfies and reliable video call quality.

Android 16 with realme UI 7 brings a clean, responsive interface with useful customisation options. Users benefit from up-to-date privacy controls, smoother animations, and a well-optimised system that keeps the phone running efficiently day to day.

The C100X covers all the everyday connectivity bases, including 4G VoLTE, Wi-Fi, and Bluetooth 5.3 with support for high-quality audio codecs like LDAC and aptX HD — useful for those who use wireless earphones. USB-C makes charging and data transfer straightforward, and the phone also supports OTG for connecting accessories directly.

The side-mounted fingerprint sensor allows quick, one-touch unlocking — a practical choice for a phone of this size. Face unlock adds another convenient option for users who prefer it. The full sensor suite supports navigation, gaming, and automatic screen adjustments.

The realme C100X supports a wide range of audio formats, making it a capable media phone for its price. Bluetooth 5.3 with support for high-quality codecs like LDAC and LHDC means wireless audio performance is notably better than what most budget phones offer, and users with good wireless earphones will notice the difference.

The 7,500 mAh battery is one of the largest available in this price segment, and it shows in real-world use. Most users will find it lasts well beyond a full day of calls, streaming, and social media. When it does need charging, 45W SUPERVOOC fast charging brings it back up quickly — so users are not stuck waiting at a plug point for long.
