The evolution of the iPhone is one of the most significant stories in modern technology. From the groundbreaking launch of the original iPhone in 2007 to the refined engineering of the iPhone 5 in 2012, Apple redefined what a smartphone could be. Today, both devices are long obsolete by official support standards, but curiosity remains: if you somehow had access to both, would the iPhone 5 still hold meaningful advantages over the original model? The answer isn't just about nostalgia—it's about practicality, functionality, and understanding how far mobile technology has come in just five years.
Design and Build: A Leap Forward
The original iPhone introduced a minimalist, all-glass front with a mechanical home button and a chunky plastic back. It was revolutionary for its time, but by today’s standards, it feels heavy and outdated. At 135 grams and 11.6 mm thick, it’s noticeably bulkier than later models.
In contrast, the iPhone 5 arrived with a sleek aluminum and glass body, weighing just 112 grams and measuring 7.6 mm thick. It was Apple’s first major redesign since the iPhone 4S, featuring an elongated 4-inch display and a Lightning connector replacing the older 30-pin dock. This shift wasn’t just aesthetic—it represented a commitment to lighter, thinner, and more durable materials.
Display and Usability
The original iPhone featured a 3.5-inch display with a resolution of 320x480 pixels (163 ppi). While sharp enough for its era, it offered limited screen real estate, making multitasking and web browsing cumbersome by modern expectations.
The iPhone 5 improved significantly with a taller 4-inch Retina display at 640x1136 pixels (326 ppi). Though the pixel density remained similar, the increased vertical space allowed for an extra row of icons and better compatibility with newer apps designed for iOS 6 and beyond. Scrolling through websites or reading emails felt smoother and more intuitive.
More importantly, the iPhone 5 supported dynamic type scaling and accessibility features that simply didn’t exist on the original model. Even in 2024, this difference translates to a marginally better reading experience—assuming the device can load modern web content at all.
Performance and Hardware Comparison
Under the hood, the gap between these two devices is vast. The original iPhone ran on a 412 MHz ARM11 processor with 128 MB of RAM. It launched with iPhone OS 1.0 and was eventually upgradable to iPhone OS 3.1.3—the final version it could support. Many core features we take for granted today, like copy-paste and third-party push notifications, were absent at launch.
The iPhone 5, meanwhile, used Apple’s custom-designed A6 chip—an estimated twice as fast CPU and triple the graphics performance over the iPhone 4S. With 1 GB of RAM and iOS 6 out of the box, it handled multitasking, HD video playback, and early versions of Siri with relative ease. It even received updates up to iOS 10, giving it nearly five years of software support.

Real-World Use Case: Can Either Phone Function in 2024?
Consider Sarah, a retro tech enthusiast who recently acquired both models from an online auction. She wanted to test whether either could serve as a functional backup phone. After charging both devices, she found the original iPhone couldn’t connect to her carrier’s network—AT&T discontinued 2G service in 2017, rendering EDGE-only phones like the original iPhone effectively offline.
The iPhone 5 fared slightly better. It powered on and connected to Wi-Fi, allowing access to saved bookmarks and locally stored music. However, Safari crashed repeatedly when loading modern websites due to outdated JavaScript engines and lack of TLS 1.2+ support. Apps like Gmail and Google Maps wouldn’t install because they require iOS 12 or higher. Even iMessage was disabled, as Apple ended support for iOS 10 in 2023.
Sarah concluded that while the iPhone 5 offers a marginally better user experience, neither device functions as a practical daily driver. Their value now lies primarily in historical appreciation and collector appeal.
Software Support and Security Risks
This is where the comparison becomes stark. The original iPhone stopped receiving updates in 2009. The iPhone 5 received its last update in 2018 (iOS 10.3.4), which included a critical time-zone fix for devices with 32-bit processors. Since then, both models have been vulnerable to unpatched security flaws.
Using either device to log into email, social media, or banking accounts poses serious risks. Modern encryption standards, phishing protections, and app sandboxing are absent. Even if the hardware worked reliably, connecting these phones to public Wi-Fi networks could expose personal data.
Step-by-Step: How to Get the Most Out of a Vintage iPhone
- Power it on and check condition: Look for battery swelling, screen cracks, or unresponsive buttons.
- Restore via iTunes: Use an old computer with legacy iTunes to wipe and reinstall the latest compatible iOS version.
- Set up as new: Avoid restoring from backup to prevent sync errors with outdated settings.
- Limit connectivity: Disable cellular data and use only private, secured Wi-Fi if needed.
- Use offline: Enjoy pre-loaded music, notes, camera (if functional), or use it as a retro gaming device.
- Store properly: Keep in a dry case with desiccant packs to prevent internal corrosion.
Frequently Asked Questions
Can the iPhone 5 still make calls in 2024?
In some regions, yes—but only if your carrier still supports GSM/3G bands used by the iPhone 5. Major U.S. carriers like Verizon and AT&T have shut down 3G networks, making voice and data services unreliable or impossible.
Is the original iPhone collectible?
Yes, especially early units in good condition with original packaging. A sealed first-generation iPhone sold at auction for over $60,000 in 2021 due to its historical significance.
Why does the iPhone 5 feel faster than the original even today?
Beyond hardware improvements, iOS 6 (on the iPhone 5) introduced optimized animations, background processes, and better memory management. The original iPhone OS lacked preemptive multitasking and efficient touch response algorithms.
Final Verdict: Is the iPhone 5 Worth It Over the Original?
In strictly technical terms, yes—the iPhone 5 is objectively superior in every measurable category: speed, display, camera, connectivity, and software longevity. It represents a mature phase of early iPhone development, whereas the original is a prototype-level device by comparison.
However, “worth it” depends on context. If you're choosing between the two as a functional smartphone in 2024, the answer is neither. Both fail to meet basic modern requirements for app compatibility, security, and network access. But if you're a collector, historian, or hobbyist, the iPhone 5 offers a more complete representation of Apple’s mobile vision circa 2012.
The original iPhone earns its place in history as a disruptor—a device that changed the industry overnight. The iPhone 5, while less revolutionary, delivered tangible improvements that shaped the next decade of smartphone design.
