HONOR 400 Smart vs Samsung Galaxy S25 Ultra

Our Verdict: Samsung Galaxy S25 Ultra has the more advanced display and camera hardware here, pairing a 505 PPI Dynamic LTPO AMOLED 2X panel with a 200MP rear camera and storage up to 1TB. HONOR 400 Smart is 30g lighter and has the larger battery capacity at 6,500mAh rather than 5,000mAh, though capacity alone cannot predict endurance. Pick the Ultra for screen sharpness, camera flexibility and IP68 protection, or the HONOR if lower weight and a large battery are more useful.

Over a full contract, the 400 Smart works out around £467 all-in, about £373 less than the S25 Ultra.
