OPPO Reno 16 vs Samsung Galaxy S25 Ultra
Our Verdict: The Samsung Galaxy S25 Ultra leads on camera hardware with a 200MP main sensor to the OPPO Reno 16's 50MP, and the Reno 16 packs the bigger battery, 6700mAh against 5000mAh, which should mean longer between charges in day-to-day use. The S25 Ultra has the stronger screen, bigger at 6.8" against 6.3" and sharper at 505 PPI, and the S25 Ultra goes up to 1TB of storage, where the Reno 16 tops out at 512GB. Only pay up for the Reno 16 if you'll use what it offers; if not, the S25 Ultra makes more sense.
Buying outright, the S25 Ultra starts at £570 SIM-free.
