What CompareTab says about OPPO F21 Pro 5G vs POCO F9 Ultra
POCO F9 Ultra has clear advantages in memory, battery capacity and display refresh rate over F21 Pro 5G, with 12 GB of RAM versus 8 GB, 256 GB of storage versus 128 GB, a 8050 mAh battery versus 4500 mAh, and a 185 Hz display instead of 60 Hz. It also adds a higher-resolution rear camera (200 MP versus 64 MP), optical image stabilization on the main camera, an ultrawide rear camera, and 100W charging. OPPO F21 Pro 5G, however, is around $446 cheaper, lighter at 173 g versus 235 g, and thinner at 7.5 mm versus 8.74 mm. The main trade-off is the F9 Ultra’s extra RAM, storage, faster charging, battery capacity, and smoother display versus the F21 Pro 5G’s lower price and lighter, thinner build.
