What CompareTab says about Realme C51 vs POCO F9 Ultra
POCO F9 Ultra offers more RAM, storage, battery capacity and a smoother display than C51, with 12 GB of RAM versus 4 GB, 256 GB of storage versus 64 GB, a 8050 mAh battery versus 5000 mAh, and a 185 Hz display instead of 90 Hz. It also adds a higher-resolution rear camera (200 MP versus 50 MP), optical image stabilization on the main camera, an ultrawide rear camera, and 100W charging. Realme C51, however, is around $670 cheaper, lighter at 186 g versus 235 g, and thinner at 7.99 mm versus 8.74 mm. The choice comes down to F9 Ultra’s extra RAM, storage, faster charging, battery capacity, and smoother display versus C51’s lower price and lighter, thinner build.
