Samsung Galaxy S23 launched February 2023 — 3 years old in 2026. Galaxy S25 launched 2025. Two generations of improvements. The Galaxy AI integration is the biggest change.
TL;DR
Upgrade if: Battery degraded, want Galaxy AI features, photo enthusiast, gaming user
Hold if: S23 working well, light user, budget tight
Wait for S26: If you can hold 6 months, S26 expected with major refresh
What Changed: S23 → S25
Processor: Snapdragon 8 Gen 2 vs Snapdragon 8 Elite
Galaxy S23 to S25 is a meaningful 2-generation upgrade, but Samsung's hardware-focused improvements aren't as dramatic as Apple's year-over-year (Galaxy AI is the major story). For most S23 users in 2026: $80-100 battery service is the smarter financial move than $400-800 upgrade.
The biggest upgrade reason is Galaxy AI — if you'd actively use Live Translate, Photo Assist, or Note Assist, S25 is justified. For typical users: S23 remains capable in 2026.
Wait for S26 (February 2026) if you can hold 6 months — major refresh expected.
