Realme C100X 4G
The Realme C100x is a smartphone designed to deliver outstanding battery life, a smooth visual experience, and a build made for everyday use. Its high-capacity Titan battery is paired with fast charging, a 120 Hz display, and ArmorShell protection to keep you going through demanding days.
In addition to water, dust, and impact resistance, it includes smart tools such as Circle to Search, Google Gemini, AI NetPilot, and a dedicated mode for improved outdoor use.
Screen
The 6.8-inch LCD offers HD+ resolution and a refresh rate of up to 120 Hz, making it easier to navigate apps, websites, and social media smoothly.
It reaches a typical brightness of 700 nits and up to 900 nits in HBM mode, improving visibility in bright environments. Its touch sampling rate of up to 240 Hz provides a faster response when gaming or navigating the interface.
The ArmorShell glass and rain-touch mode let you use the screen with greater confidence, even with wet or greasy fingers or compatible gloves.
Battery and charging
The 7,500 mAh Titan battery is designed to provide several days of light use and plenty of power for browsing, media playback, and calls. Realme has also designed the system to retain at least 80% of its capacity after seven years of use, based on its internal tests.
Fast charging of up to 45 W reduces the time spent plugged in. It also supports wired reverse charging of up to 6 W, allowing it to power other compatible devices via USB OTG.
Performance
The eight-core UNISOC T7250 processor delivers the performance needed for everyday apps, browsing, content playback, and occasional gaming. Storage can be expanded with a memory card, making it easy to keep photos, videos, and documents.
The Android 16 operating system with the realme UI interface includes features such as Google Gemini, Circle to Search, AI NetPilot, and AI Outdoor. These tools make it easier to find information, improve connectivity management, and adapt certain settings for outdoor use.
Camera
The 50-megapixel main camera features an f/1.8 aperture, autofocus, and various shooting modes, including night photography, portrait, pro mode, panorama, high resolution, and dual-view video.
It can record Full HD video at 30 fps and slow-motion video in HD resolution. The 5-megapixel front camera is designed for selfies, video calls, and high-definition video recording.
Design and durability
ArmorShell protection uses a reinforced structure, protected corners, and shock-absorbing elements to improve resistance to impacts and drops. The device has passed impact tests in accordance with the MIL-STD-810H standard, as well as internal drop tests from heights of up to two meters.
The IP64 rating certifies complete dust protection and resistance to water splashes. It should not be interpreted as protection against immersion.
The back features a configurable notification light with different colors and effects for calls, alerts, music, and the camera countdown.
Connectivity
The Realme C100x uses 4G LTE mobile connectivity and supports two Nano-SIM cards. It is not compatible with 5G networks or eSIM.
It also includes Wi-Fi 5, Bluetooth 5.2, NFC, multi-constellation GPS navigation, a USB-C port with OTG support, and a 3.5 mm headphone jack. NFC availability may vary by region, although it is listed for the European version.
