What the POCO F9 Ultra 12 GB + 256 GB Red is worth

The POCO F9 Ultra packs 12 GB of RAM and 256 GB of storage in a red finish. Its 6.9-inch AMOLED screen delivers 2,608 x 1,200 pixels at 185 Hz, with peaks of 10,000 nits on 1% of the surface. The Snapdragon 8 Elite Gen 5 built on 3 nm drives the system, backed by an 8,050 mAh battery that earns a 95/100 battery score, well above the market median of 4,500 mAh.

Photography relies on a 200 MP main sensor (f/1.68, OIS), supported by two 50 MP modules, for a 90/100 photo score. The 32 MP front camera completes the setup. Wired charging reaches 100 W, wireless charging 50 W, and the IP68-rated phone weighs 235 g at 8.74 mm thickness.

This smartphone targets those seeking exceptional battery life without compromising screen quality or camera performance. The 256 GB storage, rated 58/100 against a median of 384 GB, suits average usage, while the 12 GB RAM (80/100 score) ensures smooth multitasking. The overall 79/100 rating places it in the premium segment, above 600 euros.
