What the POCO X7 5G 8 GB + 256 GB Silver is worth

The POCO X7 5G packs 8 GB of LPDDR4X RAM, 256 GB of UFS 2.2 storage and a 6.67" screen displaying 2712 x 1220 pixels at 120 Hz. Brightness peaks at 3,000 nits outdoors, with 12-bit colour depth and full DCI-P3 gamut coverage. The 4 nm Dimensity 7300-Ultra processor drives eight cores up to 2.5 GHz, backed by a Mali-G615 MC2 GPU.

The 5,110 mAh battery scores 79/100, well above the market median. Fast charging reaches 45 W. The triple rear camera combines a stabilised 50 MP Sony IMX882 at f/1.5, an 8 MP ultra-wide at f/2.2 and a 2 MP macro at f/2.4. The 20 MP front camera at f/2.2 records 1080p at 30/60 fps. Rear 4K recording runs at 24/30 fps.

IP68 certification protects the 162.33 x 74.42 x 8.4 mm frame weighing 185.5 g. Fingerprint reader, face recognition, proximity sensor, accelerometer, electronic compass, gyroscope and infrared emitter join stereo speakers with Dolby Atmos. Connectivity includes Dual SIM 5G, Wi-Fi 6, Bluetooth 5.4, NFC and multi-constellation GPS (Galileo, BeiDou, GLONASS, QZSS).

The overall 69/100 score reflects a balance between solid battery, fluid display and decent photography. Storage at 256 GB sits slightly below the median, scoring 58/100. This model suits users seeking all-day endurance, precise visuals and fast charging within the 250 to 600 € bracket.
