OPPO Reno 16F vs Samsung Galaxy S25 Ultra

Our Verdict: Samsung Galaxy S25 Ultra and OPPO Reno 16F suit different priorities. The OPPO is stronger for portability, helped by its AMOLED panel, a higher-resolution 50MP front camera, and a larger 7,000 mAh battery, while the Samsung is better suited to a sharper 505 PPI display, its Dynamic LTPO AMOLED 2X panel, and a higher-resolution 200MP rear camera. A bigger mAh figure is useful context, but real battery life still depends on software and chipset efficiency. Choose the OPPO for portability; choose the Samsung if display quality matters more.

Over a full contract, the Reno 16F works out around £468 all-in, about £372 less than the S25 Ultra.
