What CompareTab says about Redmi 15 4G vs POCO F9 Ultra
POCO F9 Ultra has clear advantages in memory, battery capacity and display refresh rate over 15 4G, with 12 GB of RAM versus 6 GB, 256 GB of storage versus 128 GB, a 8050 mAh battery versus 7000 mAh, and a 185 Hz display instead of 144 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. Redmi 15 4G, however, is around $614 cheaper, lighter at 214 g versus 235 g, and thinner at 8.4 mm versus 8.74 mm. The choice comes down to F9 Ultra’s extra RAM, storage, faster charging, battery capacity, and smoother display versus 15 4G’s lower price and lighter, thinner build.
