iPhone 14 vs Samsung Galaxy S24 - Complete Review
iPhone 14 vs Samsung Galaxy S24 - Complete Review & Comprehensive Buying Guide
Choosing between the iPhone 14 and the Samsung Galaxy S24 represents a clash of two different eras and philosophies. While the iPhone 14 remains a staple of Apple's reliable ecosystem, the Galaxy S24 is a newer generation device boasting cutting-edge AI features and superior display technology. As a technical consultant, I have analyzed both devices extensively to help you decide if the newer Android flagship justifies the price jump, or if the older iPhone still holds its ground in 2024. This guide goes beyond the spec sheet, diving into thermal performance, PWM dimming for eye comfort, and long-term resale value.
Expert Opinion Snapshot
Before diving into the technical benchmarks, here is the executive summary for quick decision-making.
| Feature | iPhone 14 (The Safe Bet) | Samsung Galaxy S24 (The Tech Leader) |
|---|---|---|
| Best For | Social media creators, video enthusiasts, and those already in the Apple ecosystem. | Power users, display snobs, and those wanting telephoto zoom and AI tools. |
| Major Pros | • Unmatched video stability • High resale value • FaceID security • Optimized app performance | • 120Hz LTPO Display (Smoother) • 7 Years of OS Updates • Dedicated 3x Optical Zoom • Galaxy AI Features |
| Major Cons | • 60Hz Screen (Feels slow) • Slow Charging (20W) • Lightning Port (Not USB-C) | • Shutter lag in moving shots • Resale value drops faster • Exynos variant runs warmer (Region dependent) |
Full Technical Specifications
A side-by-side look at the raw hardware reveals the generation gap between these two compact flagships.

Ergonomics, Build & Materials
Both phones champion the "compact flagship" category, but they feel very different in hand. The iPhone 14 retains the notch design, which now looks dated compared to the S24's modern, tiny punch-hole camera. The Galaxy S24 has moved to completely flat sides, mimicking the iPhone's industrial design, but with slightly softer corners that dig less into the palm. The S24 is also marginally lighter and features thinner bezels, giving you more screen real estate in a body of roughly the same physical size. Expert Insight: The matte finish on the S24's back glass resists fingerprints much better than the glossy back of the standard iPhone 14. If you plan to use the phone without a case, the S24 stays cleaner.
Display Analysis: The Refresh Rate Gap
This is the most critical differentiator. The iPhone 14 utilizes a 60Hz OLED panel. In isolation, the colors are accurate and contrast is perfect. However, when placed next to the Galaxy S24, the difference is jarring. The Samsung Galaxy S24 features an LTPO panel capable of varying its refresh rate from 1Hz to 120Hz. This results in significantly smoother scrolling, system animations, and gaming. Furthermore, the S24 reaches a peak brightness of 2600 nits, making it far superior for outdoor visibility compared to the iPhone 14's 1200 nits. PWM Dimming Note: For users with sensitive eyes, the iPhone 14 uses 480Hz PWM dimming, while the S24 uses 492Hz. Both are comparable, but neither offers the high-frequency dimming (2160Hz+) seen in some Chinese competitors.
Performance, Thermals & Gaming
The iPhone 14 runs on the A15 Bionic chip (the 5-core GPU version from the iPhone 13 Pro). Despite being older, it remains an optimization beast. iOS keeps the phone feeling snappy, and it handles heavy games like Genshin Impact with remarkable stability, though it does throttle brightness after prolonged sessions. The Galaxy S24 sports the Snapdragon 8 Gen 3 (or Exynos 2400 in global markets). In raw benchmarks (Geekbench 6, Antutu), the S24 obliterates the iPhone 14. It is a generation ahead in processing power. However, thermal management is key. The smaller chassis of the S24 means heat dissipation is limited. While the S24 has a larger vapor chamber than its predecessor, it still gets warm under heavy 5G usage or 4K video recording. For daily tasks, the S24 is faster, but the iPhone 14 is surprisingly consistent.
Camera Capabilities
This is a battle of "Reliability" vs. "Versatility". iPhone 14: The dual 12MP setup takes photos that are natural, with excellent dynamic range. The standout feature is video recording. The iPhone 14 remains superior in video stabilization and seamless lens switching, making it the preferred choice for TikTok and Instagram Stories due to better app optimization. Samsung Galaxy S24: The S24 wins on hardware utility. It includes a dedicated 10MP Telephoto lens with 3x optical zoom. The iPhone 14 relies on digital crop for zoom, which results in loss of detail. The S24 also processes images with more "pop" and vibrancy. The "Nightography" mode on the S24 pulls more light in extremely dark scenarios, though sometimes at the cost of noise. Verdict: If you zoom often, buy the S24. If you shoot video primarily, stick with the iPhone 14.
Battery Endurance & Charging Speeds
The Galaxy S24 has a slightly larger 4000mAh battery compared to the iPhone 14's ~3279mAh. However, iOS is incredibly efficient with standby time. In real-world mixed usage: • iPhone 14: consistently delivers 6-7 hours of Screen On Time (SOT). • Galaxy S24: delivers similar 6-7 hours SOT, thanks to the efficient LTPO screen dropping to 1Hz when static. Charging: Neither phone is fast by modern standards. The S24 supports 25W charging, while the iPhone 14 tops out around 20W. Both take over an hour to fully charge. The S24 adds value with Reverse Wireless Charging (Wireless PowerShare), allowing you to charge earbuds on the back of the phone—a feature the iPhone lacks.
Market Value Guide (New vs Used)
Understanding the price trajectory is crucial for smart buying.
| Condition | iPhone 14 (128GB) | Galaxy S24 (128GB) |
|---|---|---|
| Brand New | ~$600 - $699 | ~$799 |
| Used / Refurbished | ~$400 - $500 | ~$550 - $650 |
| Depreciation Rate | Low (Holds value well) | Moderate (Drops faster) |
Pre-owned Inspection Checklist
If you are buying either device on the secondary market, use this checklist to avoid lemons.
| Component | How to Test (iPhone 14) | How to Test (Galaxy S24) |
| Display | Check True Tone in Control Center. If missing, screen may be non-genuine. | Dial *#0*# and select "Red/Green/Blue" to check for dead pixels. |
| Battery | Settings > Battery > Battery Health. Avoid if under 85%. | Use Samsung Members App > Diagnostics > Battery Status. |
| Security | Test FaceID. If it fails, the ambient light sensor is damaged. | Test Ultrasonic Fingerprint sensor. Ensure it registers quickly. |
Top Alternatives Comparison
If neither of these fits your exact needs, consider these strong competitors: 1. iPhone 15: Addresses the main iPhone 14 flaws by adding the Dynamic Island, USB-C, and a 48MP camera, though still stuck at 60Hz. 2. Google Pixel 8: Offers a cleaner Android experience and amazing cameras at a lower price point than the S24, but with a weaker processor. 3. Samsung Galaxy S23: Almost identical to the S24 but cheaper. If you don't care about the 7-year update promise or AI features, the S23 is better value for money.
Critical Advice
Buying New? Go for the Galaxy S24. The 7 years of software support means this phone will remain current until 2031. The iPhone 14 is already two years old, meaning it has fewer major iOS updates left in its lifecycle. Buying Used? The iPhone 14 is the safer bet. iPhones are generally more durable, and replacement parts are easier to find. Additionally, if you decide to resell it in a year, you will lose less money compared to reselling a used Android device. Storage Warning: If you buy the Galaxy S24, try to get the 256GB model. The 128GB model uses slower UFS 3.1 storage, whereas the 256GB model uses the much faster UFS 4.0 standard. The iPhone 14 uses NVMe across all storage sizes, so speed is consistent.
Final Verdict
The Samsung Galaxy S24 is objectively the better piece of hardware. It has a superior screen (120Hz vs 60Hz), a more versatile camera system (optical zoom), and a modern USB-C port. It is a true 2024 flagship. The iPhone 14, however, remains the champion of consistency. It is the phone you buy if you just want things to work, you prioritize video quality for social media, or you are locked into iMessage and FaceTime. My Recommendation: Unless you are deeply tied to Apple's ecosystem, the Galaxy S24 offers significantly more value and "future-proofing" for your money today.
