Realme C100i 4GB + 128GB, 7,000mAh Titan Battery, 4G LTE, 2 Years Warranty

The realme C100i (128GB/4GB variant) is an entry-level smartphone designed for exceptional endurance and rugged everyday durability. Launched as a specialized addition to realme's budget C-series, this device focuses on structural toughness and long-lasting power over processing muscle.

The standout trait of the realme C100i is its robust construction. Built with ArmorShell Protection, it features military-grade shock resistance (MIL-STD-810H compliant) and can withstand drops from heights up to 2 meters. It carries an IP64 dust and water resistance rating, safeguarding it against heavy rain and splashes. Weighing 208 grams with a thickness of 8.38mm, it manages to remain relatively sleek despite its massive internal components.

The device sports a large 6.8-inch HD+ IPS LCD display with a fluid 120Hz refresh rate, offering incredibly smooth scrolling and animations for its class. The panel reaches a peak brightness of 900 nits (HBM), making it highly readable outdoors. It is shielded against scratches by Corning Gorilla Glass (or Panda MN228 depending on the region) and supports a "Wet Hand Touch" mode so you can operate the phone seamlessly even with raindrops or moisture on the screen.

The realme C100i runs on the Unisoc T7250 chipset, an entry-level 12nm octa-core processor paired with an Arm Mali-G57 GPU. This specific variant features 4GB of LPDDR4X RAM and 128GB of eMMC 5.1 internal storage, which can be expanded significantly via a dedicated microSDXC card slot. Out of the box, it operates on realme UI 6.0 based on Android 16, incorporating basic AI features like Google Gemini integration, AI Outdoor Mode, and an AI Image Eraser.

Power is the phone's greatest asset. Depending on regional configurations, it carries a massive 6,500mAh to 7,000mAh Titan battery capable of yielding up to two full days of intermediate use. It supports 15W wired charging and useful reverse wired charging to charge other smaller accessories. Additionally, the phone includes an Ultra Volume Mode capable of driving the external speaker up to 300% to combat noisy city streets.

The optics are minimal and intended for basic documentation. It features an 8MP rear camera (f/2.0) with autofocus and a 5MP front selfie camera (f/2.2) housed in a waterdrop notch. Video recording tops out at 1080p at 30fps on the rear setup. It is strictly a 4G LTE device (no 5G support) that includes dual Nano-SIM compatibility, Wi-Fi 5, Bluetooth 5.2, a secure side-mounted fingerprint reader, and a traditional 3.5mm headphone jack.
