Thorough Comparison of iPhone 17 Pro and Previous-Generation iPhone 14/15/16 Pro Series

As the much-anticipated iPhone 17 series arrives and the world buzzes with talk of its latest features, smart users who are well-versed in smartphones may actually be paying attention to different models.

Indeed, it's the "Pro models" from slightly older generations, such as the iPhone 14 Pro, 15 Pro, and 16 Pro.

That's because the release of the latest model signifies the perfect timing to buy these high-performance models, as their prices on the used market become most attractive.

"The iPhone 17 is too expensive, but I don't want to compromise on performance..."
"I want to upgrade from my current smartphone at a good value."
"Which Pro model is ultimately the best fit for me?"

If you're feeling this way, then this article is exactly for you.

PRODIG, an expert in used smartphones, thoroughly compares the three Pro models you should target "now that" the iPhone 17 has been released. We'll help you find the perfect device for your usage and teach you how to get it more intelligently and affordably than anyone else.

By the time you finish reading this article, you should be able to confidently choose the iPhone that will give you the highest satisfaction, glancing past the latest model.

At a Glance! iPhone 14 Pro, 15 Pro, 16 Pro Spec Comparison Table

First, let's look at a comparison table of the main differences between the three models. You'll quickly see how high-performing these models are, even when compared to the iPhone 17.

As this table shows, each generation brings steady improvements. In particular, materials, weight, chip, camera, and connector are significant changes. In the next chapter, we'll delve into how these spec differences affect the actual user experience.

What's New? In-Depth Look at Key Evolutionary Points by Generation

The "actual user experience" that can't be gleaned from a specs table alone is the most crucial factor when choosing a model. Here, we'll delve into the evolution of each model from four perspectives: "design," "performance," "camera," and "convenience," which are likely of particular interest to men in their 20s and 30s.

Design and Feel: Is the Lightness of Titanium Justice?

Since it's a smartphone you hold every day, design and how it feels in your hand are non-negotiable points.

The iPhone 14 Pro features glossy stainless steel, offering a satisfyingly hefty and luxurious feel. Its shine still evokes a strong sense of ownership today.

On the other hand, the biggest topic for the iPhone 15 Pro is the adoption of aerospace-grade titanium. This reduced the weight by approximately 9% from 206g to 187g while maintaining durability. This "19g" difference is more significant than the number suggests; it feels noticeably lighter in hand. The burden when carried in a pocket and fatigue during long hours of operation are greatly reduced, making it an excellent upgrade for those who believe "lightness is justice."

The iPhone 16 Pro also inherits the titanium frame, while the display has increased from 6.1 inches to 6.3 inches. This not only enhances the immersive experience of watching videos and playing games but also increases the amount of information displayed at once when browsing websites and social media, allowing for more comfortable operation. While the weight of 199g is lighter than the 14 Pro but slightly heavier than the 15 Pro, it's well within an acceptable range considering the benefits of the larger screen.

Furthermore, the "Action Button," which replaced the traditional "Ring/Silent switch" starting with the iPhone 15 Pro, is also a significant evolution. It allows you to assign functions to your preference, such as launching the camera, voice memos, or specific app shortcuts, dramatically improving the iPhone's usability if mastered.

Brain (Chip) Performance Differences: How Powerful are the A16, A17 Pro, and A18 Pro?

The "A-series chip" is the heart that governs the iPhone's smooth operation. Even with the release of the iPhone 17, the performance of the chips in these Pro models remains completely unblemished.

• iPhone 14 Pro with "A16 Bionic"
  This is a very powerful chip that still holds up exceptionally well by today's standards. Everyday tasks like social media, browsing, and video viewing run smoothly, and most 3D games also perform without a hitch. Now that its used price is most affordable with the advent of the iPhone 17, getting this performance at such an astonishing price is its biggest appeal.

• iPhone 15 Pro with "A17 Pro"
  This is an innovative chip that was the first in the industry to use a 3-nanometer process. Both CPU and GPU performance have improved from the A16 Bionic, with a particularly remarkable evolution in graphics performance. The inclusion of hardware-accelerated ray tracing in the GPU allows for console-level realism in light reflections and shadow rendering in compatible games. For gamers who want to play high-quality games like "Genshin Impact" and "Call of Duty" in the best possible environment, the A17 Pro remains one of the top choices.

• iPhone 16 Pro with "A18 Pro"
  This monster chip was Apple's cutting edge until very recently. In addition to overall processing power improvements, the performance of the Neural Engine, which handles AI processing, has been significantly enhanced. This allows for full utilization of "Apple Intelligence," AI features integrated into iOS, enabling future iPhone experiences such as text correction, image generation, and a smarter Siri. It perfectly suits those who find the iPhone 17 too expensive but desire a top-tier, current-generation experience.

How Different are the Cameras? If Photography and Videography are Important to You

One of the main reasons to choose an iPhone Pro series is its outstanding camera performance. While all models take excellent photos, each generation brings definite improvements.

The iPhone 14 Pro already featured a 48MP main camera, capable of capturing beautiful, high-definition photos. It has the ability to take satisfying shots in any scene, from everyday snapshots to landscape photography.

The iPhone 15 Pro has camera hardware similar to the 14 Pro, but it has significantly evolved on the software front. This includes improved image processing capabilities thanks to the A17 Pro chip, and a next-generation portrait mode that allows you to change the focus point even after taking the picture.

And if camera performance is your priority, the iPhone 16 Pro stands head and shoulders above the rest. First, the ultra-wide camera has been significantly upgraded from 12MP to 48MP. This allows for detailed and vivid photos even with the ultra-wide lens. Furthermore, the telephoto camera now supports 5x optical zoom, bringing the powerful zoom feature previously only available on the iPhone 15 Pro Max to the more compact Pro model. This will undoubtedly be a huge advantage for events like children's sports days, concerts, and travel photography, allowing you to zoom in on distant subjects with minimal loss of image quality.

For video recording, "Log recording" and "ACES (Academy Color Encoding System)" supported since the 15 Pro are extremely powerful features for creators who want to perform serious video editing like color grading.

Battery and Charging: The Benefits of USB-C and Battery Life

Let's also check the battery performance, which is the lifeline of a smartphone, and the convenience of daily charging.

Regarding battery life, compared to the iPhone 14 Pro and 15 Pro, which offer up to 23 hours of video playback, the iPhone 16 Pro boasts a significant improvement of up to 27 hours. It's a welcome benefit that it can be used for longer periods despite the larger display. For those who frequently worry about battery levels when out and about, the iPhone 16 Pro will be a reliable companion.

And the biggest change in terms of convenience is the connector. While the iPhone 14 Pro has the traditional Lightning port, the iPhone 15 Pro and 16 Pro feature a USB-C port. This offers immeasurable benefits, as it allows you to unify charging cables across many devices, such as MacBook, iPad, the latest Android smartphones, and mobile batteries.

Furthermore, the USB-C on the 15 Pro and 16 Pro is USB 3 compatible, allowing for high-speed data transfer up to 10Gb/s (requires a compatible cable). This is up to 20 times faster compared to Lightning (USB 2)'s maximum of 480Mb/s. This dramatically reduces waiting time when transferring high-quality photos and ProRes videos to a PC, providing a significant advantage for users performing creative work.
