Samsung Galaxy S25 vs S24 vs S23: Is the Upgrade Actually Worth It in 2026?
Samsung’s Galaxy S line moves fast, and it’s easy to assume you need the newest S25 to get a good phone. I’ve dug through the spec sheets and real owner feedback on all three generations, and in practice, the S24 and even the S23 are still excellent phones — in the US market, older Galaxy flagships consistently sell well because the year-over-year jump usually isn’t as dramatic as the marketing suggests.
Here’s an honest breakdown of what changed across these three generations and which one actually fits your budget and use case.

Galaxy S25: Best If You Want the Full Galaxy AI Experience
⚡ Fastest AI Performance
The S25 is built around Samsung’s latest Galaxy AI push, with the newest chip giving those features more headroom to run smoothly. If on-device AI tools — real-time translation, generative photo editing, smarter search — are something you’ll actually use, this is the model that runs them best.
What stands out:
- Galaxy S26 Ultra vs S25 Ultra
- Fastest chip in this lineup, best suited for on-device AI processing
- Most complete and fastest-running Galaxy AI feature set
- Improved low-light camera performance
Keep in mind: Many Galaxy AI features have also been rolled out to the S24 and even the S23 via software updates, narrowing the gap.
Best for: Buyers who want the newest chip and the smoothest AI experience available right now.
Galaxy S24: The Best Balance of Price and AI Features
The S24 was the phone that introduced Galaxy AI to the mainstream lineup, and it still runs nearly the entire feature set well. A year or more after release, it typically sits at a noticeably lower price than the S25 while covering almost everything most people actually use day to day.
What stands out:
- Runs almost the full Galaxy AI suite smoothly
- Same excellent 50MP main camera as the S25
- Usually a meaningful price drop compared to the S25
Keep in mind: Slightly slower at processing the most demanding AI features compared to the S25.
Best for: Buyers who want Galaxy AI without paying the newest-model premium.
Galaxy S23: The Best Value Flagship
ud83dudcb0 Best Budget Pick
The S23 keeps showing up as a top seller in the US for a simple reason: it’s still a genuinely fast, well-built flagship at a fraction of the S25’s price. If Galaxy AI isn’t a priority for you, the core phone experience — camera, display, performance — holds up remarkably well.
What stands out:
- Lowest price of the three, often by a significant margin
- Still receives major Android and security updates
- Same core camera hardware quality as newer models for everyday photos
Keep in mind: Only a limited subset of Galaxy AI features are available, and processing them is noticeably slower.
Best for: Budget-conscious buyers who want a genuine flagship experience without the flagship price.
How to Choose: What Actually Matters
If Galaxy AI is your main reason for buying: Galaxy S25 or S24 — both run the feature set well.
If you want the best price-to-feature balance: Galaxy S24.
If budget is the deciding factor: Galaxy S23.
Frequently Asked Questions
Does the Galaxy S23 get Galaxy AI features?
Some of them, yes, through software updates — but not the full set, and processing tends to be slower than on the S24 or S25.
How long does Samsung support these phones with updates?
Samsung commits to several years of major Android updates and security patches on its flagship S series, so all three models here are still well covered.
Is the camera really that different between generations?
Not dramatically. The core 50MP main sensor has stayed similar across the S23, S24, and S25, with the biggest gains showing up in low-light processing and AI-assisted editing rather than raw hardware.
Should I wait for the next Galaxy S model instead?
If your current phone still works fine, waiting rarely hurts. But if you need a phone now, the S23 and S24 both remain strong, well-supported choices.
All three of these Galaxy flagships are still strong picks in 2026 — the right one really just comes down to how much of the newest AI features you actually plan to use. For the full technical rundown, Samsung’s own Galaxy S25 product page is worth checking before you decide.
To sum up the Galaxy S25 vs S24 vs S23 decision: the newest model is great if you want the full AI suite, but the S24 and S23 remain excellent value picks.
