Best Pre-Owned iPhone for Apple Intelligence and Siri AI:

The iPhone 15 Pro, iPhone 16 and iPhone 17e all support Apple Intelligence and Apple’s upcoming Siri AI experience.

So which one should you buy pre-owned?

At Maple, we would not decide based on the processor alone. We would compare the display, cameras, storage, battery condition and price of the actual device available.

Here is our quick answer:

Do All Three iPhones Support Siri AI?

Yes.

Apple Intelligence supports the iPhone 15 Pro and iPhone 15 Pro Max, followed by the iPhone 16 generation and later. That includes all three phones in this comparison. Apple says Siri AI will roll out as a beta for supported devices set to English. 

We have covered compatibility and Apple Intelligence features separately in our guide to Which pre-owned iPhones support Apple Intelligence.

Here, the real question is what kind of iPhone you get around the AI.

iPhone 15 Pro vs iPhone 16 vs iPhone 17e

Choose the iPhone 15 Pro for the Display and Cameras

The iPhone 15 Pro is the oldest phone here, but it offers the strongest premium hardware.

Its ProMotion display can refresh up to 120Hz, making scrolling, animations and supported games feel noticeably smoother. Its camera system includes a 48MP Main camera, an ultra-wide camera, macro photography and a dedicated 3x telephoto camera.

We would choose it when:

• You notice the difference between standard and 120Hz displays.
  
• You regularly take portraits or zoomed photographs.
  
• You use ProRAW or advanced video features.
  
• You specifically want a Pro iPhone experience.

The main issue is value.

That does not make it a poor choice. It means ProMotion and the telephoto camera must justify the additional price and the condition of the older device.

Our take: Choose the iPhone 15 Pro for its display and cameras, not simply because it supports Siri AI.

*Please check current prices before buying. Price, battery health, condition and availability may vary by unit.

Choose the iPhone 16 for the Best Overall Balance

The iPhone 16 is the easiest model for us to recommend to a broad range of buyers.

Its A18 chip supports Apple Intelligence, while its 48MP Fusion Main camera and 12MP Ultra Wide camera give you standard, 2x, wider and macro photography options. It also includes Camera Control and the Action button. 

We would choose it when:

• You want a balanced phone for work and everyday use.
  
• You take Ultra Wide or macro photographs.
  
• You do not need a dedicated telephoto camera.
  
• You want a newer device than the iPhone 15 Pro.
  
• You find a well-checked unit at a strong price.

The main question is storage.

A 128GB iPhone 16 may be the most affordable option here. Buyers who record plenty of video, keep large WhatsApp libraries or plan to retain the phone for several years should compare the 256GB version too.

Our take: The iPhone 16 is the safest all-round choice, particularly when you value its Ultra Wide camera more than additional storage.

Choose the iPhone 17e for Storage and Newer Hardware

The iPhone 17e has the newest processor in this comparison and starts with 256GB storage.

It uses the A19 chip and has a 48MP Fusion camera that provides standard and optical-quality 2x views. It also supports MagSafe charging. 

We would choose it when:

• You need 256GB.
  
• You intend to keep the phone for several years.
  
• You mainly take standard and 2x photographs.
  
• You value storage more than camera variety.
  
• Its price is close to a comparable iPhone 16.

The compromise is straightforward: The iPhone 17e does not include a separate Ultra Wide or telephoto camera.

At a similar price:

• Choose the iPhone 17e for 256GB and newer hardware.
  
• Choose the iPhone 16 for Ultra Wide and macro photography.

Because the iPhone 17e belongs to a newer generation, we would expect it to offer a longer remaining ownership runway. Apple does not promise a fixed number of software-support years for each model, so this remains a practical expectation rather than a guarantee.

Our take: The iPhone 17e can offer the strongest storage value, provided you are comfortable with its simpler camera system.

Can the Condition of the Phone Change the Answer?

Absolutely.

A healthier iPhone 16 can be a better purchase than a more worn iPhone 15 Pro. A 256GB iPhone 17e may offer better long-term value than a cheaper 128GB phone if you know you will need the additional storage.

Before you buy a pre-owned iPhone, compare:

• Battery health
  
• Storage
  
• Cosmetic condition
  
• Display and Face ID
  
• Camera operation
  
• Parts and Service History where available
  
• Activation Lock and IMEI status
  
• Remaining Apple coverage
  
• Seller warranty
  
• Final price

At Maple Store, every eligible Maple Certified Pre-Owned iPhone goes through our structured 32-step check. We check areas including identity and ownership, Activation Lock, battery behaviour, hardware, software, connectivity and cosmetic condition. 

This is why we compare the actual unit rather than recommending a model name in isolation.

Our Final Recommendation

Buy the iPhone 15 Pro when:

You want ProMotion, a dedicated telephoto camera and more advanced photography features. Its battery condition and price must justify choosing an older Pro model.

Buy the iPhone 16 when:

You want the best balance of price, cameras and everyday usability. It is our safest recommendation for most buyers, especially when 128GB is enough.

Buy the iPhone 17e when:

You want 256GB, newer-generation hardware and a longer ownership runway. It is the stronger value when its price sits close to a 128GB or 256GB iPhone 16.

Siri AI gets all three phones onto the shortlist.

The best purchase depends on what matters after that: the cameras you will use, the storage you need and the condition of the specific pre-owned iPhone in front of you.

FAQs

Q1. Which is best: iPhone 15 Pro, iPhone 16 or iPhone 17e?
A. The iPhone 16 is the safest all-round choice for most buyers. Choose the iPhone 15 Pro for ProMotion and telephoto photography. Choose the iPhone 17e for 256GB storage and newer-generation hardware.

Q2. Is an iPhone 15 Pro better than an iPhone 16?
A. The iPhone 15 Pro is better for display smoothness, optical zoom and advanced camera features. The iPhone 16 is better for buyers who want a newer device, Camera Control, Ultra Wide and macro photography, and potentially stronger pre-owned value.

Q3. Should I buy a pre-owned iPhone 16 or iPhone 17e?
A. Choose the iPhone 16 when camera flexibility matters. Choose the iPhone 17e when 256GB storage and newer hardware matter more. Compare the condition and storage of the actual devices before deciding.

Q4. Is Siri better on the iPhone 17e?
A. Apple lists the iPhone 15 Pro, iPhone 16 and iPhone 17e as supported devices and does not identify separate Siri AI feature tiers for them. The iPhone 17e has the newer A19 chip, but that alone does not make it the better purchase if you prefer the iPhone 16’s cameras or the iPhone 15 Pro’s display and telephoto lens.
