What CompareTab says about Realme C100i vs POCO F9 Ultra

POCO F9 Ultra has clear advantages in memory, battery capacity and display refresh rate over C100i, with 12 GB of RAM versus 4 GB, 256 GB of storage versus 64 GB, a 8050 mAh battery versus 6500 mAh, and a 185 Hz display instead of 120 Hz. It also adds a higher-resolution rear camera (200 MP versus 8 MP), a higher-resolution front camera (32 MP versus 5 MP), an ultrawide rear camera, and 100W charging. Realme C100i, however, is around $639 cheaper and lighter at 210 g versus 235 g. The choice comes down to F9 Ultra’s extra RAM, storage, faster charging, battery capacity, and smoother display versus C100i’s lower price and lighter build.
