In early 2018, smartphone users faced a pivotal decision: stick with Apple’s revolutionary iPhone X or go Android with Samsung’s Galaxy S9. Both devices represented the cutting edge of mobile technology at the time, but for users already on flagship phones, the upgrade question loomed large. Was trading in a perfectly functional device for either model truly worth the cost and adjustment? This analysis dives into real-world performance, long-term usability, and tangible benefits to determine whether the leap to either phone delivered meaningful value.
Design and Build: Form Meets Function
The iPhone X introduced a radical redesign for Apple—removing the home button, embracing an edge-to-edge OLED display, and adopting a glass-and-stainless-steel body. The result was sleek, premium, and unmistakably futuristic. Its 5.8-inch Super Retina display offered deep blacks and vibrant colors, setting a new standard for iOS devices.
Samsung’s Galaxy S9, meanwhile, refined an already proven formula. With its 5.8-inch Quad HD+ Dynamic AMOLED screen and symmetrical bezels, it felt familiar yet polished. The aluminum frame and glass back made it durable, and unlike the iPhone X, it retained a 3.5mm headphone jack—a small but significant detail for many users.
While both phones were water-resistant (IP68), the iPhone X’s face recognition via Face ID replaced Touch ID, marking a shift in user interaction. Some users adapted quickly; others missed the tactile feedback and speed of fingerprint scanning.
Performance and Software Experience
Under the hood, both phones packed powerful hardware. The iPhone X ran Apple’s A11 Bionic chip—an industry leader in efficiency and raw performance at launch. Paired with iOS 11 (and later updates), it delivered buttery-smooth animations, rapid app launches, and excellent multitasking even years after release.
The Galaxy S9 used either the Snapdragon 845 (in the U.S.) or Exynos 9810 (internationally), depending on region. While capable, real-world benchmarks showed the A11 consistently outperforming both processors in single-core tasks. However, Samsung’s software layer—TouchWiz rebranded as One UI—offered more customization than iOS, appealing to power users who wanted control over their interface.

iOS updates arrived faster and lasted longer. Apple supported the iPhone X with major OS upgrades until iOS 16, nearly five years post-launch. In contrast, Samsung committed to only two major Android updates for the S9, limiting its lifespan despite solid initial performance.
Camera Comparison: Photos That Matter
Both phones excelled in photography, but in different ways. The iPhone X featured a dual 12MP rear system—one wide, one telephoto—with optical image stabilization on both lenses. Apple focused on natural color reproduction, smart HDR, and consistent low-light performance. Portrait mode improved significantly with better edge detection and lighting effects.
The Galaxy S9 had a single 12MP rear sensor with a variable aperture (f/1.5–f/2.4), allowing it to adapt to lighting conditions dynamically. This gave it an edge in dim environments where wider apertures captured more light. However, processing sometimes oversaturated images, especially skies and skin tones.
| Feature | iPhone X | Galaxy S9 |
|---|---|---|
| Rear Camera | Dual 12MP (wide + telephoto) | Single 12MP (variable aperture) |
| Front Camera | 7MP with Portrait Mode | 8MP with autofocus |
| Low-Light Performance | Strong, balanced exposure | Excellent due to f/1.5 aperture |
| Video Recording | 4K at 60fps, stereo audio | 4K at 30fps, mono audio |
| Zoom Quality | 2x optical, up to 10x digital | 1x optical, up to 8x digital |
For videographers, the iPhone X was clearly superior—supporting 4K at 60fps and delivering richer sound through dual microphones. The S9’s video lacked stereo recording and smoother frame rate options, making it less ideal for content creators.
Real-World Upgrade Value: A Mini Case Study
Consider Mark, a long-time iPhone 7 user who upgraded to the Galaxy S9 in March 2018. He appreciated the brighter screen, expandable storage (via microSD), and headphone jack. But within months, he noticed inconsistent app behavior, slower update rollouts, and battery degradation by late 2019. When Android 10 launched, his device felt sluggish, and several apps began dropping support.
Conversely, Lisa switched from an iPhone 6s to the iPhone X at the same time. Despite the learning curve with Face ID and gesture navigation, she found iOS updates kept her phone feeling modern. By 2021, her iPhone X still handled daily tasks efficiently, including banking, streaming, and social media—something few S9 owners could claim.
This contrast highlights a critical factor: long-term usability. For users prioritizing future-proofing, the iPhone X offered better return on investment, even at a higher initial price.
Battery Life and Charging Realities
Battery capacity favored the Galaxy S9 (3000mAh) over the iPhone X (2716mAh), but actual endurance told a different story. Thanks to iOS optimization, the iPhone X often matched or exceeded the S9 in screen-on time. Independent tests showed both lasting around 10–11 hours of mixed usage.
Charging, however, revealed key differences. Neither came with fast charging in the box—the S9 required a separate adapter, while the iPhone X needed a USB-C to Lightning cable and a compatible power brick. Wireless charging worked well on both, supporting Qi standards.
Frequently Asked Questions
Was the iPhone X worth the $999 price tag?
For early adopters of facial recognition, edge-to-edge displays, and long-term software support, yes. The design influenced all future iPhones, and its build quality justified the premium for many. However, budget-conscious users might have found the value proposition weaker compared to previous models.
Did the Galaxy S9 justify upgrading from the S8?
Marginally. The improvements—better camera low-light performance, slightly faster processor, and revamped speaker tuning—were noticeable but not transformative. Most S8 owners saw little reason to upgrade unless their device was failing.
Which phone held resale value better?
The iPhone X retained value significantly longer. After two years, used models sold for 40–50% of original price, while Galaxy S9 units dropped to 25–30%. Apple’s ecosystem loyalty and extended software support contributed heavily to this trend.
Final Verdict: Was Upgrading Really Worth It?
For users coming from older devices—iPhone 7 or earlier, Galaxy S7 or prior—the upgrade to either phone was absolutely worthwhile. The jump in display quality, processing speed, and camera capabilities brought a genuinely next-generation experience.
However, for those already on recent flagships like the iPhone 8 or Galaxy S8, the gains were incremental. The iPhone X offered more innovation and long-term relevance, particularly with Face ID and full-screen gestures becoming standard. The Galaxy S9, while excellent, felt like an evolution rather than a revolution.
- Choose iPhone X if: You value long software support, superior video recording, seamless ecosystem integration, and are willing to pay a premium for future-proof design.
- Choose Galaxy S9 if: You prefer headphone jacks, microSD expansion, more customizable software, and prioritize still photography in low light.
- Don’t upgrade if: You’re on a recent flagship and don’t need the latest features immediately. Wait for clearer advancements or consider mid-cycle savings.
Conclusion: Make Smarter Upgrade Decisions
The iPhone X vs Galaxy S9 debate wasn’t just about specs—it was about what kind of user experience mattered most. Technology moves fast, but meaningful upgrades should enhance your life, not just your specs sheet. Whether you chose Apple’s bold new direction or Samsung’s refined excellence, the real value lies in how long your device serves you reliably.
