In 2024, choosing between older iPhones like the iPhone X and iPhone 8 isn’t just about nostalgia—it’s a practical decision for budget-conscious buyers, second-hand shoppers, or those who prefer compact devices. Both models were groundbreaking in their time, but how do they hold up nearly a decade later? The answer depends on your priorities: long-term software support, camera quality, app compatibility, or simply getting by with basic functions.
The iPhone X launched in 2017 as Apple’s 10th-anniversary flagship, introducing Face ID, an edge-to-edge OLED display, and a modern design language. The iPhone 8, released the same year, retained the traditional home button and smaller LCD screen but packed powerful internals. While both have been discontinued, they still appear in resale markets at tempting prices. But before buying one in 2024, it’s essential to understand where each stands today.
Performance and Hardware Comparison
At launch, both phones featured Apple’s A11 Bionic chip, which was revolutionary for its time. However, real-world longevity differs significantly due to hardware design and thermal management.
The iPhone X benefits from better heat dissipation thanks to its larger chassis and more advanced internal layout. This allows sustained performance during intensive tasks like gaming or video editing. The iPhone 8, while capable, tends to throttle faster under prolonged load. Over time, battery degradation has also hit the iPhone 8 harder due to its smaller capacity (1,821 mAh vs. the X’s 2,716 mAh).
| Feature | iPhone X | iPhone 8 |
|---|---|---|
| Display | 5.8\" OLED Super Retina | 4.7\" Retina HD LCD |
| Chipset | A11 Bionic (with Neural Engine) | A11 Bionic |
| Battery Capacity | 2,716 mAh | 1,821 mAh |
| Charging | Wireless + Fast Charging | Wireless + Slow Charging |
| Biometrics | Face ID | Touch ID |
| Rear Camera | Dual 12MP (wide + telephoto) | Single 12MP (wide) |
Software Support and Future Viability
This is where the iPhone X pulls ahead decisively. As of 2024, iOS 17 remains compatible with the iPhone X, though it is likely among the last supported versions. Apple typically supports devices for five to six years post-release, and since the iPhone X debuted in 2017, 2023–2024 marks its expected end-of-life window.
The iPhone 8, despite sharing the same processor, stopped receiving updates after iOS 16. It no longer supports iOS 17, making it functionally obsolete for new apps and security patches. Developers are increasingly optimizing apps for newer iOS versions, meaning even if an app installs, performance may degrade or features may be missing.

If you rely on banking apps, messaging platforms, or productivity tools, staying updated is non-negotiable. The iPhone X offers a crucial extra year or two of relevance.
Camera Quality and Everyday Use
For photography enthusiasts, the iPhone X is clearly superior. Its dual-camera system enables 2x optical zoom, Portrait Mode for both people and lighting effects, and better low-light performance due to sensor improvements and image stabilization on both lenses. The front-facing TrueDepth camera also supports Portrait Mode selfies—a feature absent on the iPhone 8.
The iPhone 8’s single rear camera captures decent photos in daylight but struggles in dim conditions. No optical zoom means digital cropping degrades quality quickly. Video recording is limited to 4K at 60fps, whereas the X supports extended dynamic range and better audio sync.
Realistically, neither matches modern mid-range Android cameras, but the X delivers noticeably crisper images and more creative flexibility.
Mini Case Study: Sarah’s Upgrade Dilemma
Sarah, a freelance writer in Portland, wanted a reliable backup phone without spending over $150. She considered both the iPhone 8 and X on eBay. After testing both in-store at a local reseller, she noticed the iPhone 8 lagged when switching between Safari tabs and failed to update to iOS 17. The iPhone X booted faster, had smoother animations, and supported her note-taking app’s latest features. Despite costing $40 more, she chose the X—and replaced the battery for $60. Two months later, she reports it handles email, web browsing, and Zoom calls effortlessly.
When the iPhone 8 Might Still Be Good Enough
The iPhone 8 isn’t entirely obsolete. For users with minimal tech demands—such as seniors using the phone primarily for calls, texts, and simple apps like weather or flashlight—it remains functional. Touch ID is faster and more reliable than early Face ID in certain lighting conditions. The compact size fits comfortably in small hands or pockets, appealing to those who dislike large smartphones.
Additionally, the iPhone 8’s glass back supports wireless charging, and its IP67 rating means it can survive brief water exposure. With a fresh battery and iOS 16, it can serve as a dedicated music player, car phone, or emergency device.
- Best for: Light users, kids, secondary devices
- Not suitable for: App-heavy workflows, social media creators, secure banking
- Lifespan expectation: 1–2 years max with moderate use
Checklist: Is This iPhone Right for You?
Before purchasing either model, go through this checklist:
- ✅ Verify iOS version: iPhone X should run iOS 17; iPhone 8 capped at iOS 16
- ✅ Check battery health: Must be above 85% or budget for replacement
- ✅ Test Face ID / Touch ID: Ensure biometric sensors work reliably
- ✅ Confirm storage: 64GB minimum recommended; avoid 16/32GB variants
- ✅ Inspect physical condition: Look for cracked screens, water damage indicators
- ✅ Consider future needs: Will you need newer apps or features in 2025?
FAQ
Can the iPhone 8 get security updates after iOS 16?
No. Once a device stops receiving major OS updates, it also ceases to get regular security patches. Critical vulnerabilities may go unpatched, increasing risk over time.
Is the iPhone X waterproof?
It has an IP67 rating, meaning it can withstand immersion in up to 1 meter of water for 30 minutes. However, water resistance diminishes over time, especially if the seals are damaged.
Should I upgrade the battery on either phone?
Yes—if the current battery health is below 80%, expect poor daily performance. Apple charges around $69 for out-of-warranty battery service, and third-party shops offer replacements for $40–$60.
Final Verdict: Which One Should You Choose?
In 2024, the iPhone X remains the smarter choice for anyone planning to use the device regularly beyond a few months. It supports the latest iOS, handles modern apps well, offers better cameras, and provides a more immersive display experience. While aging, it still delivers a surprisingly usable smartphone experience with proper maintenance.
The iPhone 8, meanwhile, is only advisable for very light usage or as a temporary solution. Its lack of iOS 17 support severely limits its utility, and dwindling app compatibility will accelerate its obsolescence. Unless you’re buying it for $50 or less—or handing it to someone who only makes calls—it’s hard to justify over newer budget alternatives like the iPhone SE (3rd gen) or even entry-level Androids.
