In 2024, choosing between the iPhone 12 and the Samsung Galaxy S20 isn’t just about specs—it’s about long-term value, ecosystem loyalty, and how well a three-year-old flagship holds up in today’s demanding mobile landscape. Both devices were top-tier in 2020, but time has tested their resilience. The question now isn’t which was better at launch, but which remains more practical, reliable, and future-proof today.
This isn’t a nostalgic look back. It’s a real-world evaluation of two aging flagships facing modern expectations: app bloat, high-resolution video streaming, multitasking demands, and security updates. Whether you’re considering a secondhand purchase or deciding whether to keep your current device, this breakdown delivers clarity on what truly matters in 2024.
Performance and Longevity: How Do They Handle Modern Use?
The iPhone 12 runs on Apple’s A14 Bionic chip, while the Galaxy S20 uses either the Snapdragon 865 (in the U.S.) or Exynos 990 (in some international markets). At launch, both chips were leaders in mobile processing, but their long-term trajectories have diverged significantly.
Apple’s silicon consistently outperforms Android counterparts in sustained workloads and efficiency. The A14, despite being older in architecture, still handles iOS 17 with ease. Apps launch quickly, multitasking is smooth, and even newer games run without throttling. iOS optimization plays a major role—fewer background processes, tighter memory management, and uniform hardware across models mean less strain over time.
Samsung’s S20, however, shows signs of aging. While the Snapdragon 865 was powerful, the Exynos variant struggled with heat and power efficiency. Even on Snapdragon models, One UI 5 and later versions have introduced heavier animations and background services that slow down the experience. Users report occasional stutters when switching between apps or using split-screen mode.
Software Updates and Security: The Hidden Lifeline
One of the most critical factors in 2024 is software support. The iPhone 12 is eligible for iOS 18, expected later this year, and could receive updates through 2026. That means five years of major OS upgrades—a rarity in the smartphone world.
In contrast, the Galaxy S20 received four major Android updates (up to Android 13) and five years of security patches. As of early 2024, it no longer receives monthly security updates. This gap in ongoing support is significant: outdated software increases vulnerability to malware, limits compatibility with banking and productivity apps, and reduces access to new features.
“Long-term software support is now a primary differentiator. iPhones maintain functionality and security far longer than most Android flagships.” — David Lin, Mobile Security Analyst at TechShield Labs
For users concerned about privacy or those who rely on secure apps (like corporate email or financial tools), continued patching is non-negotiable. The iPhone 12 clearly wins here, offering peace of mind well into 2025 and beyond.
Camera Comparison: Real-World Results in 2024
Both phones launched with strong camera systems, but their evolution under software updates tells a different story.
The iPhone 12’s dual-camera setup (12MP wide and ultra-wide) benefits from Apple’s computational photography. Smart HDR 4, Deep Fusion, and Night mode are constantly refined through software. In 2024, its photos remain consistent—natural color science, excellent dynamic range, and reliable low-light performance. Video recording is unmatched, supporting Dolby Vision HDR at 4K/60fps, a feature still rare among competitors.
The Galaxy S20’s 64MP telephoto, 12MP main, and 12MP ultra-wide system offered versatility in 2020. However, aggressive pixel binning and inconsistent HDR tuning have aged poorly. Many users report washed-out skies, oversharpened textures, and sluggish autofocus in low light. While Samsung improved processing over time, the lack of recent updates means no further enhancements.
| Feature | iPhone 12 | Galaxy S20 |
|---|---|---|
| Low-Light Photo | Excellent (Night mode) | Good, but noisy |
| Video Quality | Dolby Vision 4K/60fps | 4K/60fps (no HDR support) |
| Zoom Performance | 2x optical, digital beyond | 3x hybrid zoom |
| Front Camera | 12MP, TrueDepth | 10MP, f/2.2 |
| Software Improvements | Ongoing (iOS 17+) | Stopped at Android 13 |
If you prioritize photo consistency and video quality—especially for social media or content creation—the iPhone 12 continues to deliver where the S20 falls short.
Battery Life and Charging: Practical Daily Use
Battery health is a silent killer for older phones. After three years, even well-cared-for batteries degrade. The iPhone 12 originally had a 2,815mAh battery; the S20, 4,000mAh. On paper, Samsung wins. But real-world endurance depends on software efficiency and charging habits.
iOS’s power management is more aggressive. Background app refresh is limited, location tracking is stricter, and display brightness adapts intelligently. As a result, the iPhone 12 often lasts a full day with moderate use—even with a degraded battery. Fast charging (20W) and MagSafe offer convenient top-ups.
The S20 supports faster charging (25W) and wireless power sharing, but One UI tends to keep more apps active in the background. Over time, this drains the battery faster, especially if not optimized. Additionally, Android’s adaptive battery learns usage patterns but can be less effective on older hardware.
Ecosystem and Resale Value: The Hidden Advantages
Apple’s ecosystem creates lock-in—but also long-term value. If you own AirPods, a Mac, or an Apple Watch, the iPhone 12 integrates seamlessly. Handoff, AirDrop, iCloud sync, and Continuity Camera enhance productivity. These features don’t exist on Android, making the switch costly in terms of convenience.
Resale value is another area where the iPhone dominates. A used iPhone 12 in good condition retains 40–50% of its original value in 2024. The Galaxy S20, meanwhile, sells for 20–30%, reflecting lower demand and shorter software support. For budget-conscious buyers, this makes the iPhone a smarter investment—even if the upfront cost was higher.
“I’ve kept my iPhone 12 since 2020. It got iOS 17, runs all my apps, and my wife uses it as her secondary phone now. The S20 I gave to my nephew lagged within a year.” — Marcus T., Software Developer, Chicago
FAQ
Can the iPhone 12 still run the latest apps smoothly?
Yes. Most apps on the App Store are optimized for A12 and later chips. The iPhone 12 handles social media, streaming, gaming, and productivity tools without issue in 2024.
Is the Galaxy S20 obsolete in 2024?
Not entirely, but it’s limited. Without security updates and major OS upgrades, it’s risky for sensitive tasks. It can still function as a secondary device or for basic use, but not as a primary smartphone for most users.
Should I buy either phone new in 2024?
No. Neither is sold new by carriers or retailers. If purchasing, opt for certified refurbished units with replaced batteries and updated software. Prioritize the iPhone 12 for longer usability.
Checklist: Choosing Between iPhone 12 and Galaxy S20 in 2024
- ✅ Check software version: iPhone should be on iOS 17, S20 on Android 13
- ✅ Verify battery health: Replace if below 80% capacity
- ✅ Confirm storage: 128GB minimum recommended for long-term use
- ✅ Avoid Exynos variants of the S20
- ✅ Test cameras and charging ports before purchase
- ✅ Prefer iPhone if using other Apple devices
- ✅ Consider resale value if planning to upgrade in 1–2 years
Conclusion: Is the iPhone 12 Still Worth It?
In 2024, the iPhone 12 stands as a testament to Apple’s long-term vision. It delivers consistent performance, ongoing software support, superior camera processing, and ecosystem integration that the Galaxy S20 simply can’t match after its update cycle ended. While the S20 was a formidable competitor in 2020, it has not aged gracefully under the weight of modern software demands and security expectations.
For anyone seeking a reliable, secure, and functional smartphone without paying flagship 2024 prices, the iPhone 12 remains a compelling choice—especially in the refurbished market. It proves that in the smartphone world, longevity isn’t just about hardware. It’s about sustained support, intelligent optimization, and a commitment to user experience over time.
