What the Galaxy S26 changes
The newest Samsung phone in this line is the Galaxy S26 at £879, released 6 March 2026. Judged row by row against our published thresholds; the full table is at Galaxy S26 vs Galaxy S25.
On the makers’ published figures, the Galaxy S26 wins on storage (base) (256 GB against 128 GB) and battery per charge (51 h against 37.27 h); the Galaxy S25 wins on battery lifespan (2,000 cycles against 1,200 cycles). One gap is borderline, a difference most people would not notice: 3DMark Wild Life Extreme (6,531 against 5,664, both from 3DMark) for the Galaxy S26. The differences in weight, display size, battery capacity and claimed video playback are below the thresholds you would notice. Both state the same refresh rate, peak brightness, RAM, fast charging and wireless charging. The other 34 rows have no threshold or no direction to judge by, so nobody wins them.
- Storage (base): 128 GB → 256 GB
- Battery per charge: 37.27 h → 51 h

Our reading of the figures
The Galaxy S25 is committed to security updates until 31 January 2032, so nothing forces a move yet.
The Galaxy S26 clears our noticeable threshold on 2 rows: storage (base), battery per charge. One more gap is borderline, which most people would not notice. You would give up battery lifespan.
At £879 new, less the £296 CeX was paying for a grade A Galaxy S25 on 2025-10-03, the move costs about £583.
