The Galaxy S25 Ultra costs £555 more than the S24 Ultra.
You get: faster wireless charging and a faster chip.
You give up: nothing in the specs we compare.
Worth it if you want faster wireless charging and a faster chip. Keep the money if those extras don’t matter to you.
The Galaxy S25 Ultra charges faster without a cable (25 W vs 15 W on the S24 Ultra), so cable-free top-ups are quicker.
The Galaxy S25 Ultra's chip (Qualcomm Snapdragon 8 Elite) scores higher in benchmark tests than the one in the S24 Ultra (Qualcomm Snapdragon 8 Gen 3), so it should feel quicker in demanding apps and games.
Both have a similar size (162.8 × 77.6 mm and 162.3 × 79 mm) and a similar thickness (8.2 mm and 8.6 mm), close enough not to matter much day to day.
