OPPO Reno 16 vs Samsung Galaxy S25 Ultra

Our Verdict: Samsung Galaxy S25 Ultra and OPPO Reno 16 suit different priorities. The Samsung is stronger for display quality, helped by a larger 6.8-inch screen, a sharper 505 PPI display, and its Dynamic LTPO AMOLED 2X panel, while the OPPO is better suited to its AMOLED panel, a higher-resolution 50MP front camera, and a larger 6,700 mAh battery. A bigger mAh figure is useful context, but real battery life still depends on software and chipset efficiency. Choose the Samsung for display quality; choose the OPPO if portability matters more.

Over a full contract, the Reno 16 works out around £608 all-in, about £232 less than the S25 Ultra.
