The iPhone X was a landmark device—Apple’s first edge-to-edge OLED display, Face ID, and a design language that shaped years of future iPhones. Released in 2017, it was revolutionary for its time. The iPhone 12, arriving three years later in 2020, brought 5G, a flat-edge design reminiscent of the iPhone 5, and a more powerful A14 Bionic chip. Now, in 2024, many iPhone X owners are asking: should I finally upgrade? With both devices still functional and occasionally found in refurbished markets, this comparison isn’t just nostalgic—it’s practical.
For users clinging to an aging iPhone X, the decision hinges on real-world usability, software support, and whether the benefits of newer hardware justify the cost. Let’s analyze the key differences and determine if the jump from iPhone X to iPhone 12 holds meaningful value today.
Design and Build: Evolution of Form
The iPhone X introduced a glass-and-stainless-steel design with curved edges and a notch-centric front. It felt premium but was prone to cracks and had a glossy back that attracted fingerprints. The iPhone 12 adopted aerospace-grade aluminum edges and a flatter design, making it easier to grip and more compatible with modern MagSafe accessories.
Both phones feature glass backs for wireless charging, but the iPhone 12 uses tougher Ceramic Shield front cover, which Apple claims offers better drop performance. In everyday use, the iPhone 12 feels more durable and aligns better with current accessory ecosystems.
Performance and Software Longevity
The heart of any smartphone is its processor. The iPhone X runs on the A11 Bionic chip—a powerhouse in 2017 but now significantly outpaced by modern silicon. The iPhone 12, equipped with the A14 Bionic, remains capable of handling iOS 17 and is expected to support iOS 18 and possibly iOS 19.
In practical terms, this means smoother multitasking, faster app launches, and better longevity. Apps like Snapchat, Instagram, and video editors have grown more demanding, and the A11 can struggle with extended use or high-resolution media processing. The A14 handles these tasks effortlessly, even in 2024.
“Devices with A12 and later chips are far more future-proof. The A14 in the iPhone 12 ensures at least two more years of reliable updates.” — Mark Tran, Mobile Analyst at TechPulse Insights
iOS updates are critical. As of 2024, the iPhone X supports up to iOS 16, but no longer receives major feature updates. Security patches may continue sporadically, but core functionality improvements have ended. The iPhone 12, meanwhile, remains fully supported and benefits from features like App Library, improved Focus modes, and enhanced privacy controls.
Camera Comparison: Night Mode and Computational Photography
Cameras have evolved dramatically between these models. The iPhone X has a dual 12MP rear system (wide and telephoto) without Night mode. Low-light photos often appear grainy or underexposed. The iPhone 12 introduces Night mode across all lenses, Deep Fusion image processing, and Smart HDR 3—resulting in sharper details, better dynamic range, and vastly superior low-light performance.
In daylight, both phones produce solid images, but the iPhone 12 consistently delivers richer color accuracy and better noise reduction. Video capabilities also leap forward: the iPhone 12 supports Dolby Vision HDR recording at 4K up to 60fps, while the iPhone X maxes out at 4K 30fps without advanced stabilization or HDR.
| Feature | iPhone X | iPhone 12 |
|---|---|---|
| Rear Cameras | Dual 12MP (Wide, Telephoto) | Dual 12MP (Wide, Ultra-Wide) |
| Night Mode | No | Yes (all cameras) |
| Video Recording | 4K@30fps, no HDR | 4K@60fps, Dolby Vision HDR |
| Front Camera | 7MP TrueDepth | 12MP TrueDepth |
| Slofies (Slow Motion Selfie) | No | Yes |
If photography matters—even casually—the iPhone 12’s camera system is a substantial upgrade. Capturing moments in dim lighting or wanting crisper group selfies makes the newer model a clear winner.
Battery Life and Charging: Real-World Endurance
Apple rated the iPhone X for up to 13 hours of video playback. The iPhone 12 improves slightly to around 17 hours, thanks to more efficient architecture and larger battery capacity relative to screen size. However, real-world usage shows a more nuanced picture.
With iOS 17 and modern app demands, the iPhone 12 typically lasts a full day with moderate use, including social media, messaging, and some streaming. The iPhone X, especially with aged batteries, often struggles past midday without a recharge. Battery health degradation is common in units from 2017, and replacements—while possible—are an added cost.
Charging is another differentiator. Both support Fast Charging and Qi wireless charging, but the iPhone 12 adds MagSafe, enabling snap-on chargers, wallets, and accessories. This ecosystem integration enhances convenience and opens new utility beyond what the iPhone X offered.
Mini Case Study: Sarah’s Upgrade Journey
Sarah used her iPhone X daily from 2018 to early 2024. By late 2023, she noticed apps taking longer to load, frequent crashes in messaging apps, and poor photo quality during evening events. After replacing the battery in December 2023, performance improved briefly, but iOS lag persisted.
In February 2024, she upgraded to a refurbished iPhone 12. Immediate changes included faster Face ID response, smoother scrolling in Instagram, and dramatic improvement in night photos of her toddler. She also adopted a MagSafe wallet, eliminating the need to carry a separate cardholder. “It feels like going from dial-up to broadband,” she said. “I didn’t realize how much I was missing until I upgraded.”
Is the Upgrade Worth It in 2024? A Practical Checklist
Before spending money on a new (or refurbished) iPhone 12, consider your current needs. Use this checklist to evaluate whether the upgrade makes sense:
- ✅ Is your iPhone X experiencing slow performance with everyday apps?
- ✅ Have you noticed frequent app crashes or freezing?
- ✅ Are you unable to update to the latest iOS version?
- ✅ Do your photos look blurry or grainy, especially at night?
- ✅ Is battery life less than a full day on normal use?
- ✅ Do you want access to 5G, MagSafe, or better video recording?
If three or more apply, the iPhone 12 upgrade is likely worthwhile. Even in 2024, it delivers tangible improvements in speed, camera quality, and ecosystem compatibility.
Frequently Asked Questions
Can the iPhone X still be used in 2024?
Yes, but with limitations. It runs iOS 16, lacks modern security updates, and may struggle with newer apps. Basic tasks like calling, texting, and light browsing remain functional, but expect reduced reliability over time.
Does the iPhone 12 support 5G, and does it matter in 2024?
Yes, the iPhone 12 supports 5G. While not essential for everyone, 5G improves download speeds, streaming quality, and future-proofs your device. In areas with strong coverage, it enhances cloud gaming, video calls, and large file transfers.
Is buying a refurbished iPhone 12 a good idea?
Absolutely. Refurbished units from Apple or trusted retailers often come with warranties and battery health above 80%. Given the iPhone 12’s age, this is a cost-effective way to gain several more years of solid performance.
Final Verdict: Taking the Leap in 2024
The iPhone X was a pioneer, but technology moves quickly. By 2024, its hardware is outdated, software support has stalled, and user experience lags behind modern expectations. The iPhone 12, while no longer Apple’s flagship, remains a highly capable device with meaningful advantages: faster performance, better cameras, longer software support, and access to modern features like MagSafe and 5G.
For iPhone X users still holding on, the upgrade isn’t about chasing novelty—it’s about reclaiming responsiveness, reliability, and relevance in a digital world that expects more from its devices. If you rely on your phone for work, communication, or capturing life’s moments, the iPhone 12 represents a justified and practical step forward.
