Is it any good?
The C100x is a 4G phone with a battery bigger than most 5G phones realme makes: 8,000 mAh, sold as 4GB + 64GB for ₹17,999. It is for buyers who find 4G enough and want as much battery as the money allows.
It runs a UNISOC T7250 with realme UI on Android 16, and has a 6.8-inch 120Hz LCD, 45W charging, 6W reverse charging, a 50MP rear camera, a 3.5mm headphone jack, a microSD slot and IP64 splash resistance.
The catch is that ₹3,000 more buys the NARZO 100x 5G, with the same 8,000 mAh battery and 45W charging plus 5G, a Dimensity 6300 and a 144Hz screen. At 219g the C100x is also heavy for a 4G phone, and no update promise is published. Unless the budget stops at ₹17,999, the NARZO is the better buy.
