Quick verdict

Verdict

The realme C100i is best approached as a battery-first everyday phone. Its 6500mAh battery, 120Hz display, 4GB RAM, UFS 2.2 storage and Android 16 provide a balanced base for calls, messaging, web use and media. The 8MP rear and 5MP front cameras are simple rather than versatile, and 15W charging is modest for such a large battery. It makes most sense for buyers who value screen size, battery capacity and essential connectivity over advanced cameras or 5G.
