Samsung Galaxy S25 vs Samsung Galaxy Z Fold8

Our Verdict: Comparing Samsung Galaxy S25 and Samsung Galaxy Z Fold8, the choice mostly comes down to display quality versus portability. The Z Fold8 gives you a larger 7.6-inch screen, its LTPO AMOLED 2X panel, and a larger 4,800 mAh battery, while the S25 is more appealing for its Dynamic LTPO AMOLED 2X panel and a lighter 162g body. A bigger mAh figure is useful context, but real battery life still depends on software and chipset efficiency. Choose the Z Fold8 for display quality; choose the S25 if portability matters more.

Over a full contract, the S25 works out around £645 all-in, about £730 less than the Z Fold8.
