OPPO Find X9 Ultra vs Samsung Galaxy S25
Our Verdict: The OPPO Find X9 Ultra has the better camera on paper, 200MP versus 50MP, plus a 50MP selfie camera against 12MP, and the X9 Ultra has the bigger battery of the two, 7050mAh against 4000mAh, which should mean longer between charges in day-to-day use. The X9 Ultra has the stronger screen, bigger at 6.8" against 6.2" and sharper at 510 PPI, and the Samsung Galaxy S25 is the lighter phone at 162g against 235g. The X9 Ultra is the one to have if you want what it adds, but the S25 is the smarter buy if you'd rather keep the money.
The S25 is the cheaper one to own: around £593 over a typical contract, £728 less than the X9 Ultra.
