Performance and Software (One UI 8 / Android 16)
The Samsung Galaxy S24 delivers some of the best performance you can find in a compact flagship — even in 2025. Powered by the Snapdragon 8 Gen 3 for Galaxy, it offers a major leap in CPU and GPU efficiency compared to the S23 lineup, with faster app launches, smoother multitasking, and noticeably better thermal management. Whether you’re gaming, recording 4K videos, or juggling multiple apps, the S24 holds peak performance longer without overheating.
One UI 8 (Android 16), released in late 2025, brings a polished software experience with improved speed, better animations, enhanced privacy tools, and deeper AI integration. Samsung’s latest version of One UI introduces a range of Galaxy AI features, including:
- Live Translate: Real-time, two-way voice translation during calls
- Circle to Search: Instantly search anything on the screen with a single gesture
- Chat Assist: Helps rewrite messages, adjust tone, and correct grammar
- Generative Photo Editing: Background fill, object removal, and AI enhancements
- Battery & App Optimization: Adaptive power controls that extend runtime
More importantly, S24 is the first model that Samsung promises seven years of major Android upgrades and security patches. Since it launched with Android 14 (One UI 6) in 2024, it will receive updates through at least Android 21 (One UI 13) and security updates well into 2031.
This combination of blazing-fast hardware, efficient battery usage, and long-term software support makes the Galaxy S24 one of the most future-proof Android phones you can buy in 2025 — especially at refurbished pricing.
Camera and Display Quality
The Galaxy S24 delivers premium camera performance that still competes with newer 2025 devices. Its triple-camera system — 50MP main, 12MP ultrawide, and 10MP telephoto — offers sharp details, excellent color accuracy, and improved low-light quality thanks to Samsung’s upgraded image processing engine.
Low-light photography benefits greatly from improved noise reduction and multi-frame processing, delivering brighter, clearer shots with more natural skin tones. The 10MP 3x telephoto lens is one of the best in its class, offering consistent zoom performance without loss of detail. Samsung’s computational photography pipeline has also improved HDR handling, reducing blown highlights and shadow crush in high-contrast scenes.
On the video side, the S24 continues Samsung’s tradition of strong stabilization and crisp 4K 60fps recording. AI enhancements help improve exposure, reduce shake, and maintain clarity during fast movement — making the S24 a reliable choice for vloggers or users who frequently record video.
The display is another major strength. The 6.2-inch Dynamic AMOLED 2X panel offers:
- Up to 2600 nits peak brightness — excellent for outdoor use
- FHD+ resolution with vivid colors and deep contrast
- 120Hz adaptive refresh rate for smooth scrolling and battery efficiency
- HDR10+ support for rich media playback
Compared to the Galaxy S23, the S24 offers brighter output, better color balance, and more accurate tone mapping, resulting in richer, more immersive visuals whether you're streaming movies or playing games.
In short, the Galaxy S24’s camera and display quality remain flagship-level in 2025 — making it a top-tier choice for photography, content creation, and multimedia consumption.
Battery Life and Charging
Despite its compact size, the Samsung Galaxy S24 delivers impressive battery performance in 2025 thanks to its efficient Snapdragon 8 Gen 3 for Galaxy processor and optimized power management in One UI 8 (Android 16). The 4000 mAh battery provides reliable all-day endurance, even for medium-to-heavy users.
Real-world battery performance includes:
- 6–7 hours of screen-on time for typical daily use
- Improved efficiency during gaming and high-brightness tasks
- Better standby battery life due to optimized background processes
- Adaptive refresh rate adjustments for lower power draw
Charging performance remains solid. The S24 supports:
- 25W wired fast charging (0–50% in about 30 minutes)
- 15W wireless charging
- Wireless PowerShare for charging accessories like Galaxy Buds or smartwatches
While charging speeds haven’t increased from the previous generation, the improved efficiency of the Snapdragon 8 Gen 3 makes the S24 last longer on a single charge compared to the S23. Most users can comfortably get a full day of use without needing a midday top-up.
For a compact flagship, the Galaxy S24 offers some of the best battery optimization Samsung has achieved — delivering consistent, dependable longevity in daily use.
Price and Value in 2025
In 2025, the Samsung Galaxy S24 stands out as one of the best-value compact flagship phones in the refurbished market. According to UpTrade’s Price Tracker, Certified Used or Refurbished Galaxy S24 models start at around $230+, a steep drop from its original $799 launch price.
At this price point, the S24 offers:
- Flagship performance at a midrange cost

Value Alternative — Galaxy S23
For shoppers who want premium performance at an even lower cost, the Galaxy S23 is one of the strongest alternatives to the S24 in 2025. While it’s a year older, it still offers flagship-level performance, excellent cameras, and the same software experience with One UI 8 (Android 16). And with Certified Used / Refurbished prices starting around $170+, it delivers exceptional value for buyers looking to maximize savings.

Key Differences
1. Chip Upgrade & Performance Boost
The Galaxy S24’s Snapdragon 8 Gen 3 for Galaxy delivers faster speeds, better heat control, and improved GPU performance compared to the S23’s Snapdragon 8 Gen 2. Both are powerful chips, but the S24 handles demanding tasks like high-frame-rate gaming, heavy multitasking, and AI features more smoothly — giving it longer usability over time.
2. Galaxy AI Enhancements
While both models run One UI 8 (Android 16), only the S24 supports the full suite of Galaxy AI features. This includes better on-device translation, enhanced photo editing tools, and improved natural-language processing. The S23 receives many AI upgrades through software, but some processor-intensive features remain exclusive to the S24.
3. Camera Tuning & Image Processing
The camera hardware is nearly identical, but the S24 benefits from improved computational photography. It offers brighter low-light images, more accurate skin tones, and better HDR performance. The S23 is still excellent, but the S24 produces more balanced photos — especially in challenging lighting.
4. Display Brightness
This is one of the biggest differences:
- Galaxy S24: 2600 nits peak brightness
- Galaxy S23: 1750 nits peak brightness
Outdoors, the S24 remains significantly more readable under harsh sunlight. Indoors, both look great, but the S24 offers more accurate color calibration and improved contrast handling.
5. Battery Optimization & Efficiency
Although the batteries are similar in size, the Snapdragon 8 Gen 3 inside the S24 is more efficient than the 8 Gen 2. The S24 consistently lasts longer during video playback, gaming, and high-brightness use. The S23’s battery is still solid — but the S24 offers more reliable all-day endurance.
6. Software Support
While S23 comes with the standard 4 years of Android Upgrade and 5 years of Security Updates, the S24 has a 7-year commitment from Samsung for both Android Upgrade and Security Updates. In other words, S23 will get support until 2028, but S24 has been extended to 2031.
Which One Should You Buy?
Pick the Galaxy S24 if you want the best long-term value, full AI feature set, brighter display, and longer update support.
Pick the Galaxy S23 ($170+) if you want to save money while still getting a fast, compact, flagship-level phone with excellent cameras and software support through 2028.
Both are excellent devices — but the S24 is the better long-term choice, while the S23 is the best budget-friendly flagship option in Samsung’s 2025 lineup.
