For millions of iPhone 6 owners, the decision to upgrade to the iPhone X wasn’t just about new features—it was a generational shift. Released four years apart, these two devices represent vastly different eras in Apple’s design philosophy and technological capability. The iPhone 6, launched in 2014, brought larger screens to the mainstream. The iPhone X, released in 2017 as Apple’s 10th-anniversary flagship, introduced Face ID, an edge-to-edge OLED display, and a radical redesign. But does that leap justify the cost for long-time iPhone 6 users? Based on real-world feedback, performance benchmarks, and usability insights, here's an in-depth look at whether the upgrade truly delivers.
The Design Leap: From Curves to Glass and Stainless Steel
The physical transformation between the iPhone 6 and iPhone X is dramatic. The iPhone 6 featured a compact aluminum body with curved edges and a home button anchoring the interface. In contrast, the iPhone X adopted a premium glass-and-stainless-steel build, removing the home button entirely and replacing it with gesture navigation and Face ID.
Users consistently praised the iPhone X’s modern aesthetic. “It feels like stepping into the future,” said Mark T., a longtime iPhone 6 owner who upgraded in early 2018. “The screen takes up almost the entire front, and the phone feels more solid, more intentional.” However, some noted that the glass back makes it more prone to cracks if dropped, a trade-off for wireless charging support—a feature absent on the iPhone 6.
Tip: If you're upgrading from iPhone 6, invest in a protective case immediately—especially one that covers the edges, since the iPhone X’s glass is more fragile than the aluminum chassis.Performance and Speed: A Night-and-Day Difference
Under the hood, the gap is staggering. The iPhone 6 runs on the A8 chip with 1GB of RAM, while the iPhone X packs the A11 Bionic chip and 3GB of RAM. This translates to significantly faster app launches, smoother multitasking, and far better handling of graphics-intensive games and augmented reality apps.
Real-world tests show the iPhone X completing tasks up to four times faster than the iPhone 6. Apps like Instagram, which often lagged or crashed on older hardware, open instantly on the iPhone X. Safari scrolls fluidly, even with multiple tabs open—a common pain point on the iPhone 6 by 2017.

Display Quality: Retina HD vs. Super Retina OLED
The iPhone 6’s 4.7-inch LCD screen was sharp for its time, but the iPhone X’s 5.8-inch Super Retina OLED display represents a quantum leap in visual quality. OLED technology delivers true blacks, higher contrast ratios (1,000,000:1), and more vibrant colors. HDR video playback and improved color accuracy make streaming services like Netflix and YouTube noticeably better.
Despite the larger screen, the iPhone X remains manageable thanks to optimized bezel-free design. Many users initially worried about one-handed use, but adaptive gestures and Reachability mode help bridge the gap.
| Feature | iPhone 6 | iPhone X |
|---|---|---|
| Display Type | Retina HD LCD | Super Retina OLED |
| Screen Size | 4.7 inches | 5.8 inches |
| Resolution | 1334 x 750 | 2436 x 1125 |
| Contrast Ratio | 1400:1 | 1,000,000:1 |
| True Tone Support | No | Yes |
Camera Improvements: More Than Just Megapixels
The camera system sees one of the most meaningful upgrades. The iPhone 6 has a single 8MP rear camera without optical image stabilization (OIS) for stills. The iPhone X boasts a dual 12MP setup—one wide-angle, one telephoto—with OIS on both lenses, Portrait Mode, and Portrait Lighting effects powered by the A11 chip’s neural engine.
In practical terms, this means sharper low-light photos, crisper zoom capabilities (up to 10x digital zoom with decent quality), and professional-looking depth effects. Front-facing performance also jumps dramatically: the iPhone X’s 7MP TrueDepth camera enables Animoji, better selfies, and accurate Face ID mapping.
Jamie R., a photography enthusiast, shared: “I didn’t think I’d care so much about Portrait Mode until I used it. My family portraits now have that soft background blur you usually see in DSLR shots. It’s not perfect, but it’s impressive for a phone.”
Battery Life and Charging: Incremental Gains
Battery life improves, but not as drastically as other areas. Apple rated the iPhone X for up to two hours more usage than the iPhone 6. In real-world testing, most users reported gaining about 1.5 extra hours of screen-on time. While helpful, heavy users may still need midday charging.
The bigger change is in charging options. The iPhone X supports fast charging (up to 50% in 30 minutes with a compatible charger) and Qi wireless charging—neither available on the iPhone 6. These conveniences add subtle but lasting value over time.
Tip: To maximize battery longevity, enable Optimized Battery Charging in Settings > Battery > Battery Health. This reduces wear by learning your daily charging habits.Mini Case Study: Sarah’s Upgrade Journey
Sarah M., a teacher from Portland, used her iPhone 6 for nearly four years before upgrading to the iPhone X in late 2018. Her old phone struggled with iOS 12—apps froze, messages delayed, and battery drained by noon. After switching, she noticed immediate improvements.
“My school uses a lot of iPad-integrated apps, and the iPhone X handles them seamlessly,” she said. “I can now record student progress videos without lag, scan documents faster, and even use Face ID while wearing gloves via a third-party workaround. The upgrade paid for itself in saved time.”
However, Sarah did face a short learning curve. “I missed the home button at first. Swiping up took practice. But within a week, it felt natural.”
Is the Upgrade Worth It? A Practical Checklist
Before making the jump, consider these factors. Use the checklist below to evaluate your needs:
- App Performance: Are apps crashing or loading slowly on your iPhone 6?
- Camera Needs: Do you want better photos, especially in low light or with depth effects?
- Security: Would you benefit from Face ID over Touch ID?
- Software Support: Is your iPhone 6 still receiving updates? (Note: iOS 12 was its final major update.)
- Budget: Can you afford the cost, or would a newer model offer better value today?
If three or more apply, the upgrade likely makes sense—even years after the iPhone X’s release, many users found it revitalizing.
Frequently Asked Questions
Can the iPhone X still run the latest iOS versions?
The iPhone X supports up to iOS 16, but not iOS 17. While it no longer receives major updates, it remains secure and functional for everyday use with current apps.
Is Face ID reliable compared to Touch ID?
Most users report Face ID is faster and more convenient in daily use, especially when unlocking while walking or typing. However, it can struggle with masks, extreme angles, or very low light. Touch ID is more consistent in those scenarios.
Should I upgrade directly to a newer model instead?
If buying today, models like the iPhone 12 or later offer better long-term support, improved cameras, and 5G connectivity. However, if you already own an iPhone X or find one at a steep discount, it’s still a massive leap from the iPhone 6.
Final Verdict: A Transformative, If Costly, Upgrade
Moving from the iPhone 6 to the iPhone X isn’t just an upgrade—it’s a redefinition of what an iPhone can be. The removal of the home button, the immersive display, the powerful processor, and advanced camera system collectively create an experience that feels modern and future-ready, even by today’s standards.
While the financial investment was significant at launch, long-term users consistently report high satisfaction. The speed, reliability, and usability gains address the core frustrations of aging iPhone 6 hardware. Yes, there’s a learning curve. Yes, the glass is fragile. But for those ready to leave the past behind, the iPhone X delivers a compelling next chapter.
