As we move deeper into 2024, many smartphone users are reevaluating their devices—not just for upgrades, but for platform shifts. The iPhone 13 and Galaxy S21, though released years apart from today’s flagships, remain in active use thanks to strong performance and continued software support. For Android loyalists considering iOS—or vice versa—the question isn’t just about specs. It’s about ecosystem fit, longevity, user experience, and whether changing platforms delivers real benefits now.
This comparison dives beyond raw numbers to examine how these two phones perform in everyday life, how they’ve aged, and what switching actually means in terms of cost, convenience, and future-proofing.
Performance and Longevity: How Do They Hold Up?
The iPhone 13 runs on Apple’s A15 Bionic chip, a powerhouse even by 2024 standards. Paired with iOS optimization, it continues to deliver smooth multitasking, fast app launches, and efficient background management. Most users report no slowdown after two years—rare for smartphones—and Apple promises iOS updates through at least 2027, possibly longer.
The Galaxy S21, powered by the Exynos 2100 or Snapdragon 888 (depending on region), was top-tier in 2021. But both chips have shown thermal throttling under sustained load, and over time, some users notice lag in heavier apps. Samsung has committed up to four major Android OS updates and five years of security patches, meaning the S21 received its final update in 2025. In 2024, it’s functional—but not future-proof.
Camera Comparison: Real-World Results Matter
Both phones launched with impressive camera systems, but their philosophies differ. The iPhone 13 uses computational photography to produce natural colors, excellent dynamic range, and reliable low-light performance. Its Smart HDR 4 and Deep Fusion technologies work silently in the background to enhance detail without oversaturation.
The Galaxy S21 leans into vibrancy. Its 64MP telephoto and 12MP main sensor capture sharp images with rich contrast, especially in daylight. However, aggressive processing can lead to unnatural skin tones and blown-out highlights. Night mode is capable, but often less consistent than Apple’s implementation.
In video, the iPhone 13 dominates. With Dolby Vision HDR recording up to 4K at 60fps, it remains unmatched in its class. The S21 supports 8K, but file sizes are massive and stabilization lags behind.
“Apple’s consistency in photo quality across lighting conditions gives it an edge for users who want 'set it and forget it' reliability.” — Jordan Lee, Mobile Photography Analyst
Software Experience: Ecosystem Lock-In Is Real
This is where the “switching teams” decision becomes more than technical—it becomes behavioral. iOS and Android offer fundamentally different workflows.
- iOS emphasizes simplicity, privacy controls, tight integration with Macs, iPads, and Apple Watches, and uniformity across apps.
- Android offers customization, file system access, multi-tasking flexibility, and broader hardware compatibility.
If you’re deeply invested in Google services (Gmail, Drive, Photos), switching to iPhone may feel disruptive. Conversely, if you own a MacBook or AirPods, staying on Android means missing seamless handoff, Universal Clipboard, and optimized audio tuning.
In 2024, iCloud has improved cross-platform access, and Samsung’s integration with Windows via Link to Windows helps bridge gaps. But subtle advantages—like iMessage effects, FaceTime grid view, or Samsung DeX desktop mode—can tip the balance depending on your habits.

Real User Scenario: Sarah Switches from S21 to iPhone 13
Sarah had used Samsung phones since 2016. When her Galaxy S21 began slowing down in late 2023, she considered upgrading within the Android ecosystem but noticed her new MacBook wasn’t syncing seamlessly with her phone. After borrowing a friend’s iPhone 13, she tested continuity features: instant hotspot, clipboard sharing, and Find My linking with her AirPods.
She made the switch in early 2024. While she missed the high refresh rate display and expandable storage, she gained faster app performance, longer update assurance, and smoother integration with her other devices. After three months, she reported spending less time troubleshooting and more time being productive.
“It wasn’t the camera or battery that sold me,” she said. “It was how everything just worked together.”
Step-by-Step Guide: Making the Switch in 2024
Moving between ecosystems requires planning. Follow this timeline for a smooth transition:
- Week 1: Audit Your Data – Identify essential apps, photos, contacts, and accounts. Back up your Galaxy S21 to Google Drive and export any local files.
- Week 2: Set Up iCloud – Create or sign in to your Apple ID. Enable two-factor authentication and set up Family Sharing if needed.
- Day of Switch: Use Move to iOS – During iPhone setup, select “Move Data from Android.” This secure tool transfers messages, contacts, photos, calendars, and free apps.
- First Week: Reinstall Paid Apps – Download equivalents from the App Store. Some Android apps don’t have iOS versions, so research alternatives ahead of time.
- Second Week: Optimize Settings – Customize notifications, enable Focus modes, set up Siri, and link Apple Watch or AirPods if applicable.
Checklist: Before You Switch Platforms
- ✅ Verify carrier compatibility and unlock status
- ✅ Back up all data from current device
- ✅ Check app availability on the target platform
- ✅ Transfer subscriptions (e.g., Samsung Pay → Apple Wallet)
- ✅ Prepare for differences in UI navigation (gesture controls vary)
- ✅ Consider accessory compatibility (chargers, cases, earbuds)
Frequently Asked Questions
Can I use my Galaxy Buds with an iPhone?
Yes, but with limitations. Galaxy Buds will connect via Bluetooth, but you’ll lose features like firmware updates, ambient sound controls, and seamless switching. For full functionality, Apple’s AirPods are recommended.
Will my iPhone 13 still get updates in 2025?
Yes. Apple typically provides 5–6 years of iOS updates. The iPhone 13 launched with iOS 15 and has already received iOS 16, 17, and will likely receive iOS 18 and 19. Security updates will continue beyond that.
Is the Galaxy S21 obsolete in 2024?
Not entirely. It still handles daily tasks well, but lacks newer features like satellite connectivity, advanced AI photography, and long-term patch support. It’s best suited for light users or as a secondary device.
Final Verdict: Should You Switch?
For Android users attached to customization and open file systems, sticking with the Galaxy S21—or upgrading within Samsung’s lineup—makes sense. But if you value long-term reliability, ecosystem cohesion, and consistent software updates, the iPhone 13 offers a compelling upgrade path—even in 2024.
The real advantage isn’t just in specs; it’s in sustainability. The iPhone 13 will likely outlive the S21 by 1–2 years in both performance and support. And for users already in Apple’s ecosystem, switching back feels less like a change and more like coming home.
If you're frustrated with slowdowns, update uncertainty, or poor cross-device integration, making the jump could be one of the most impactful tech decisions you make this year.
