The iPhone 4S, released in 2011, was a landmark device—featuring Siri for the first time and a design that defined Apple’s early smartphone era. Fast forward to the iPhone 11 Pro, launched in 2019, and you’re looking at a powerhouse with triple cameras, OLED display, and A13 Bionic chip. But does upgrading from an iPhone 4S to an iPhone 11 Pro in 2024 make sense? With nearly a decade between them, the technological leap is massive—but so are cost, practicality, and personal needs.
For users still clinging to an iPhone 4S—perhaps out of nostalgia, minimalism, or budget constraints—the idea of jumping straight to a modern flagship like the 11 Pro raises real questions. Is the upgrade truly necessary? Can the 11 Pro justify its price when used today? And what tangible benefits will you actually experience?
Performance & Hardware: A Quantum Leap
The gap in processing power between these two phones isn't just wide—it's astronomical. The iPhone 4S runs on Apple’s A5 chip, a dual-core processor with 512MB of RAM. It struggled with multitasking even in 2012. By contrast, the iPhone 11 Pro features the A13 Bionic chip, a 6-core CPU with 4GB RAM, neural engine, and advanced GPU capabilities. This isn’t evolution; it’s revolution.
On the iPhone 4S, loading a single web page over 3G can take 10–15 seconds. Apps frequently crash or fail to launch. iOS updates stopped at iOS 9.3.5, meaning no support for modern apps like Google Maps, WhatsApp, or Instagram beyond very limited versions—if they work at all.
The iPhone 11 Pro runs iOS 17 (and supports iOS 18), handles 4K video editing, plays graphics-intensive games smoothly, and manages dozens of background apps without lag. Safari loads complex pages instantly. Machine learning tasks—like photo recognition or voice processing—are handled in real time.
Camera Comparison: From Basic Snapshots to Professional Photography
The iPhone 4S has an 8MP rear camera with no flash stabilization, poor low-light performance, and no front-facing camera capable of quality selfies. Video tops out at 1080p at 30fps, and there’s no slow motion or portrait mode.
The iPhone 11 Pro changed the game with a triple-camera system: 12MP ultra-wide, wide, and telephoto lenses. Features include Night mode, Deep Fusion, Smart HDR, 4K video at 60fps, and cinematic stabilization. You can shoot professional-grade photos in near darkness, switch seamlessly between lenses, and capture detail invisible to older sensors.
In practical terms, this means sharing high-resolution photos on social media, scanning documents clearly, using FaceTime in HD, and capturing memories with clarity that simply wasn’t possible a decade ago.
“Smartphone photography today is less about hardware and more about computational intelligence. The 11 Pro processes multiple frames per second to create one perfect image.” — David Lin, Mobile Imaging Analyst at TechScope Review
Display, Battery, and Daily Usability
The iPhone 4S has a 3.5-inch LCD screen with a resolution of 960x640 pixels. While sharp for its time, it feels cramped by today’s standards. Text is harder to read, videos are constrained, and touch responsiveness is sluggish compared to modern capacitive screens.
The iPhone 11 Pro boasts a 5.8-inch Super Retina XDR OLED display with 2436x1125 resolution. Colors are vibrant, blacks are true, and brightness adjusts dynamically. Reading e-books, browsing websites, or watching YouTube becomes a vastly superior experience.
Battery life is another critical factor. The 4S lasts about 6–7 hours with light use and lacks fast charging. The 11 Pro offers up to 18 hours of video playback, supports fast charging (50% in 30 minutes), and works with wireless chargers.

Real-World Example: Maria’s Upgrade Journey
Maria, a 68-year-old retiree from Portland, had been using her iPhone 4S since 2012. She resisted upgrading because she “only uses it for calls and texts.” But last winter, her bank notified her that their app would drop support for iOS 9 devices. Suddenly, she couldn’t check her balance or pay bills.
She bought a used iPhone 11 Pro for $220 from a certified reseller. Within days, she learned to use FaceTime with her grandchildren, scan receipts with Notes, and navigate using Google Maps. “It felt like I went from horse and buggy to a spaceship,” she said. “But now I feel connected again.”
Her story reflects a broader truth: staying on outdated hardware doesn’t just limit convenience—it risks exclusion from essential services.
Is the Upgrade Worth It in 2024?
Yes—but only if you need functionality beyond basic calling. If your goal is to send messages, set reminders, and occasionally browse the web, alternatives exist. Refurbished Android phones under $100 offer modern app compatibility and decent performance.
However, if you want reliability, long-term software support, seamless integration with other Apple devices (like AirPods or Apple Watch), and future-proofing, the iPhone 11 Pro remains a compelling option—even in 2024. Used models are widely available, often under $250, and many still have excellent battery health and full functionality.
Step-by-Step Guide to Upgrading Smartly
- Evaluate your needs: List what you currently can’t do on your 4S (e.g., video calls, mobile banking).
- Set a budget: Decide how much you’re willing to spend—consider refurbished options.
- Research sellers: Buy from reputable sources like Apple Certified Refurbished, Swappa, or Best Buy Renewed.
- Backup your data: Use iCloud or iTunes to transfer contacts and photos (if supported).
- Set up your new device: Follow Apple’s setup assistant, enable Find My iPhone, and update to the latest iOS.
- Learn key features: Spend time exploring the camera, Siri, and accessibility settings.
Frequently Asked Questions
Can the iPhone 4S still be used safely in 2024?
No—not for anything involving personal data. Without security updates since 2016, the 4S is vulnerable to malware, phishing, and unpatched exploits. Even web browsing poses risks. Using it for online banking or email is strongly discouraged.
Will apps work on the iPhone 4S today?
Very few. Most major apps—including Facebook, WhatsApp, Gmail, and Zoom—require iOS 12 or higher. The App Store itself no longer functions properly on iOS 9, making downloads nearly impossible.
Is the iPhone 11 Pro still supported?
Yes. It runs iOS 17 and is expected to receive updates through iOS 18 or 19, likely until 2025. Security patches continue for several years after feature updates end.
Final Verdict: Upgrade for Functionality, Not Just Speed
Upgrading from an iPhone 4S to an iPhone 11 Pro isn’t just about faster performance—it’s about joining the current digital world. The 11 Pro offers secure access to banking, healthcare portals, communication tools, navigation, and entertainment platforms that the 4S simply cannot support.
If you’ve held onto the 4S for sentimental reasons or simplicity, consider this: modern smartphones can be customized to be minimalist. Turn off notifications, delete unused apps, and use grayscale mode. You’ll gain security and capability without digital overload.
The technology gap between these two phones represents more than eight years of innovation. In human terms, that’s a generation. Bridging it isn’t frivolous—it’s necessary for participation in everyday life.
