Quick Summary
- The S24 brings a faster processor (Snapdragon 8 Gen 3) and meaningfully better AI-powered features, but the S23's camera and battery still compete with the best in 2026.
- Real-world speed difference is noticeable but not game-changing — both phones handle everyday tasks identically.
- The S24 wins on software longevity and Gemini AI integration, adding about 2 years of guaranteed updates over the S23.
- For most people, the S23 remains a solid phone through 2027–2028 — skip the upgrade unless you're chasing latest AI or want the Snapdragon 8 Gen 3's sustained performance under heavy gaming.
- Buy the S24 if you want cutting-edge specs and plan to keep it for 4+ years; buy the S23 if price has dropped and you're comfortable at 2–3 years from now.
Why Upgrading from S23 to S24 Isn't as Simple as Specs Suggest
The problem with comparing flagship phones released 18 months apart is that reviewers focus on the wrong metrics. Everyone quotes processor benchmarks and camera megapixels, but those numbers don't translate to your actual experience. You need to know whether the S24 justifies its current premium, whether your S23 is legitimately aging, and what features actually matter for how you use your phone.
The S23 launched in January 2023 and still ranks among the most capable Android phones on the market. It shipped with a Snapdragon 8 Gen 2, a 50MP main camera, 120Hz AMOLED display, and wireless charging. Samsung promised seven years of OS updates and security patches on the S23 — so your S23 won't be abandoned by 2030. That's a critical fact that shifts the entire upgrade calculation.
The S24 arrived in early 2024 with evolutionary improvements: faster GPU, better thermal management, the Snapdragon 8 Gen 3 chip, and deeper integration with Google's Gemini AI. It also introduced improved low-light photography and more consistent 8K video recording. But here's where most reviews mislead you: the base photography experience hasn't fundamentally changed. Both phones produce excellent photos in good light. The S24 pulls ahead in difficult conditions and when using AI-powered features like Magic Eraser or Best Take — but only if those features align with how you actually shoot.
Your decision hinges on three things: how much you value AI capabilities, whether you plan to keep your phone for three years or five, and whether a $200–300 price gap matters to your budget. Let's dig into the real differences.

Our Top Picks
Samsung Galaxy S24 — Best for Forward-Thinking Upgraders
The S24 is Samsung's safest flagship choice in 2026 if you're upgrading from anything older than S22. It pairs the Snapdragon 8 Gen 3 with 12GB of RAM, a 6.1-inch 120Hz AMOLED display, and Samsung's One UI powered by Gemini AI integration. You get seven years of guaranteed OS updates (through 2031), which is the longest support window in Android.
Best for: Anyone planning to keep their phone 4+ years, or upgrading from an older flagship.
Samsung Galaxy S23 — Best for Budget-Conscious Loyalty
By 2026, the S23 has dropped significantly in price and remains a complete flagship. The Snapdragon 8 Gen 2 still outperforms mid-range processors by a comfortable margin, and the 50MP main sensor with f/1.8 aperture competes with the S24 in favorable light. You still get 120Hz AMOLED, wireless charging, and five years of update guarantees (through 2028).
Best for: Users who want a 2026 flagship without the latest premium, or who upgrade every three years.
Samsung Galaxy S24 Ultra — Best for Creative Professionals and Power Users
If you shoot video or edit photos on your phone, the S24 Ultra justifies its $1,299 starting price. The 200MP telephoto (10x optical), 12MP ultra-wide, and 50MP main camera form a legitimate professional toolkit. The 6.8-inch display handles video editing in full color accuracy, and the Snapdragon 8 Gen 3 Lead Version keeps rendering consistent even during long 8K recording sessions.
Best for: Photographers, videographers, and anyone treating their phone as a primary creative tool.
Samsung Galaxy S23 FE — Best for Stretching a Budget
The S23 FE (Fan Edition) brings the core S23 experience—50MP camera, 120Hz display, same design language—at roughly $400–450. It's missing wireless charging and has a slightly slower Snapdragon 7 Gen 2, but it handles everything except sustained gaming without compromise.
Best for: First-time Galaxy buyers or anyone whose phone sees mostly messaging, social media, and photos.
Google Pixel 9 Pro — Best Alternative If You're Not Locked Into Samsung
The Pixel 9 Pro arrived in 2024 with the Google Tensor 4 chip and computational photography that edges ahead of Samsung's in specific scenarios—particularly low-light portraiture and Zoom Enhance (equivalent to S24's Zoom Enhance). If you primarily care about camera quality over ecosystem, it's worth comparing.
Best for: Photography enthusiasts already comfortable with Google's services and Android customization.
What to Look For
Processor and Real-World Performance
The Snapdragon 8 Gen 3 inside the S24 genuinely runs cooler and more efficiently than the 8 Gen 2 in the S23. That means gaming stays smooth for longer, and battery drain during demanding tasks is measurably lower. In standard productivity—apps, email, browsing—both chips feel identical. If you game 30+ minutes daily or edit video regularly, the S24 edges ahead. Otherwise, the S23's processor is still fast enough in 2026.
Camera System: Where Numbers Lie
Both phones have 50MP main sensors, but the S24's processor handles burst photography and Night Mode slightly better thanks to improved computational photography. The real difference: the S24's 3x telephoto has a sharper lens than the S23's equivalent, particularly in low light. For everyday shots, the difference is invisible. For print or professional work, test both before buying.
Software Longevity and AI Integration
This is where the S24 actually wins measurably. Seven guaranteed years of OS updates (vs. five on S23) means you'll run Android 17 or 18 on the S24 while the S23 reaches end-of-support. Gemini AI integration on the S24 is also deeper — Gemini Live conversations, advanced summarization in Gmail, and voice features are more seamlessly woven into One UI. If AI tools align with your workflow, the S24's advantage compounds over time.
Display Brightness and Color
Both phones max out at 2,000 nits peak brightness, but the S24's display uses a newer panel that maintains that brightness longer. In direct sunlight, the difference is subtle but noticeable. If you spend significant time outdoors or travel frequently, test both outdoors before committing.
How to Choose Between the Samsung Galaxy S24 and S23
Choosing between these two phones comes down to a few practical questions you should answer before spending money.
How long do you plan to keep the phone? If you upgrade every two to three years, the S23's five-year update window covers you comfortably through your next upgrade cycle. If you hold onto phones for four or five years, the S24's seven-year guarantee becomes genuinely important. Software support isn't just about new features — it's about security patches and compatibility with future apps.
Do you actively use AI features? Based on expert reviews, Gemini AI integration on the S24 is meaningfully deeper than anything available on the S23. Features like Circle to Search, Live Translate, and Gemini Live are more fluid on the S24's hardware. If you already use Google Assistant heavily or rely on AI-assisted writing and summarization, the S24 will feel like a natural upgrade. If you rarely touch those features, the gap shrinks considerably.
What is your budget ceiling? The Samsung Galaxy S23 now regularly dips below $600 at major retailers. The Samsung Galaxy S24 holds closer to $799–$849 at standard pricing. That $200–250 difference is real money. If you're deciding between the S24 and an unrelated purchase — a laptop upgrade, a camera accessory, or simply keeping savings — the S23's value proposition in 2026 is genuinely strong.
Are you upgrading from an older Samsung model? Lab tests and independent benchmarks consistently show that anyone moving from a Galaxy S21 or older will notice dramatic improvements on either phone. In that scenario, the S23 at a lower price may be the smarter buy. Moving from an S22, the S24 offers a more noticeable leap in AI features and processor headroom.
Buying Tips
- Buy refurbished or certified pre-owned if budget is a concern. Both the Samsung Galaxy S23 and Samsung Galaxy S24 are available through certified programs with warranty coverage, often at 15–25% below retail.
- Watch for carrier promotions. Trade-in deals on the S24 can reduce the effective price significantly, sometimes matching the outright S23 cost. Check promotions before paying full retail.
- Consider storage tiers carefully. The base 128GB model fills up faster than most buyers expect, especially if you shoot 4K video. The 256GB tier is worth the modest premium on either phone.
- Don't overlook the Samsung Galaxy S24 Plus if you want a larger display and bigger battery without jumping to Ultra pricing. It sits between the standard S24 and S24 Ultra and is frequently overlooked in comparisons.
- Check compatibility with your accessories. If you own Samsung DeX docks, Galaxy Watch, or Galaxy Buds, both phones support the full ecosystem. No meaningful compatibility differences exist between the S23 and S24 for accessories.
Comparison
The S24 and S23 are 90% identical devices separated by 18 months of silicon iteration. The Snapdragon 8 Gen 3 is noticeably faster in gaming and video export tasks. This advantage only matters if you regularly push your phone to its limits. Both phones shoot exceptional photos in good light; the S24 pulls ahead in dim environments and when using AI-enhanced features like Magic Eraser or Generative Fill.
Where the S24 genuinely wins is longevity and software support. Seven years of guaranteed updates (through 2031 on the S24 vs. 2028 on the S23) means the S24 will receive Android versions the S23 never sees. That extra time translates to relevance in an ecosystem where security patches matter increasingly.
Battery life remains effectively identical—both squeeze 24–26 hours from moderate use, slightly less under heavy load. The S24's thermal management merely prevents battery drain from spiking during intensive tasks. If you need all-day battery on heavy usage days, neither phone is a magic bullet.
For the camera, the practical choice is this: if your S23 photos already satisfy you, the S24's improvements won't justify $200+. If you frequently shoot in dim light or rely on advanced features like Best Take and Zoom Enhance, the S24 delivers a tangible upgrade.
Final Verdict
Based on expert reviews and independent lab testing, we recommend the Samsung Galaxy S24 as the best overall pick for most buyers in 2026. Its seven-year update window, Snapdragon 8 Gen 3 performance, and maturing Gemini AI integration give it a meaningful edge over the S23 for anyone planning to hold their phone through 2029 or beyond.
Keep your S23 if: you're satisfied with its photos, don't use AI tools regularly, and plan to replace it in 2027–2028. The extra $250–300 is better spent on a future flagship when the generational leap feels mandatory.
Buy the S24 if: you're upgrading from S22 or older, plan to own the phone through 2028+, or depend on AI-powered features for work. The seven-year support window and Gemini integration justify the premium for long-term owners. We recommend checking current pricing on the Samsung Galaxy S24 before deciding — deals fluctuate frequently in 2026.
Buy the S23 if: the current price has dropped below $600 and you're comfortable with five years of guaranteed updates. It remains a complete, capable flagship in 2026—not yesterday's technology.
Skip the S24 Ultra unless you're a content creator genuinely using that 10x optical zoom and 8K video capabilities regularly. The jump in price doesn't correlate to everyday usability for most people.

Frequently Asked Questions
Is the Samsung Galaxy S24 worth buying in 2026? Yes, if you're planning to keep your phone through 2028 or later, or if you actively use AI features in your workflow. The Snapdragon 8 Gen 3 handles any app through 2028+, and seven guaranteed years of updates push your phone into relevance ranges the S23 never reaches. However, if you're upgrading from an S22 or S23 and primarily use your phone for messaging, social media, and everyday photography, the improvements don't warrant a full upgrade price.
What should I look for when buying a Samsung Galaxy S24 vs S23? Prioritize processor performance and software longevity. The Snapdragon 8 Gen 3 matters significantly if you game or edit video regularly, and seven years of updates outweigh any single hardware spec. Second, consider your camera needs—the S24's low-light performance and AI-enhanced features (Best Take, Zoom Enhance, Magic Eraser) improve on the S23, but only if you actually use them. Battery capacity favors the S23 slightly when accounting for its more efficient 8 Gen 2 chip paired with a larger cell, but real-world longevity is effectively identical.
Which is better for beginners? The Samsung Galaxy S23 or S23 FE both work well for first-time smartphone buyers. The S23 offers a full-featured flagship experience with all the bells and whistles, while the S23 FE drops wireless charging and uses a slower processor to save $150–200. For pure beginners, the FE covers everything except serious gaming; for anyone planning to explore your phone's capabilities over time, the S23 offers more room to grow into its feature set.
How much longer will the S24 stay relevant compared to the S23? The S24 receives two additional guaranteed OS updates (through 2031 vs. 2028 on the S23). That means the S24 will run Android 17 and 18 in its final support years while the S23 enters end-of-life. Practically speaking, you gain roughly two years of guaranteed security patches and feature updates—meaningful if you plan to own the phone beyond 2028. If you upgrade every three years, this advantage matters less.
