OPPO A 6x 4G vs Samsung Galaxy S25
Our Verdict: The Samsung Galaxy S25 leads on camera hardware with a 50MP main sensor to the OPPO A 6x 4G's 13MP, plus a 12MP selfie camera against 5MP, and only the S25 is a 5G phone; the A5 2020 6x 4G maxes out at 4G. The A5 2020 6x 4G has the bigger battery of the two, 6500mAh against 4000mAh, which usually means longer between charges, and the A5 2020 6x 4G has the bigger screen at 6.8" against 6.2", while the S25 has the sharper one at 416 PPI. Only pay up for the S25 if you'll use what it offers; if not, the A5 2020 6x 4G makes more sense.
The A5 2020 6x 4G is the cheaper one to own: around £257 over a typical contract, £336 less than the S25.
