OPPO A 6x 4G vs Samsung Galaxy S25 Edge
Our Verdict: The Samsung Galaxy S25 Edge has the better camera on paper, 200MP versus 13MP, plus a 12MP selfie camera against 5MP, and only the S25 Edge is a 5G phone; the OPPO A 6x 4G maxes out at 4G. The A5 2020 6x 4G has the bigger battery of the two, 6500mAh against 3900mAh, which should mean longer between charges in day-to-day use, and storage goes higher on the S25 Edge, up to 512GB against 128GB. Only pay up for the S25 Edge if you'll use what it offers; if not, the A5 2020 6x 4G makes more sense.
Over a full contract, the A5 2020 6x 4G works out around £257 all-in, about £451 less than the S25 Edge.
