Realme C100i Summary
The Realme C100i enters the budget mobile segment with an emphasis on rugged everyday durability and long-lasting battery power. Featuring an 8.38mm slim body profile and a solid 208-gram weight, the phone incorporates an ArmorShell protective structure built with reinforced corners. It carries an IP64 dust and splash resistance rating alongside MIL-STD-810H shock compliance, offering added peace of mind against accidental drops, pressure, and rain.
At its core, the device is powered by the 12nm Unisoc T7250 octa-core processor combined with 4GB of LPDDR4X RAM and 64GB of internal storage. Daily tasks run smoothly through virtual memory expansion options that allow allocation of up to 12GB of total active RAM, while an onboard hybrid card slot supports extra physical microSD storage expansion up to 2TB.
Running Realme UI 6.0 built on Android 16, the system provides a user-friendly layout loaded with practical utility tools like AI Clear Face and Smart Image Matting.

Backed by a large 6,500 mAh battery with 15W wired fast charging and reverse charging capability, the smartphone offers reliable battery stamina across multiple days of routine use.
