In 2025, the iPhone 13 Pro Max remains one of the most popular smartphones in the secondhand market. With its powerful A15 Bionic chip, premium design, and pro-level cameras, it still holds strong value. However, as technology rapidly advances — especially now that AI has become a core feature of next-generation smartphones — deciding whether to sell, trade in, or continue using it requires careful consideration.

 

Overview of the iPhone 13 Pro Max Secondhand Market in 2025

 

Data from online marketplaces and refurbished stores indicate that while demand for the iPhone 13 Pro Max still exists, prices are trending downward. This is mainly because users are shifting to newer versions such as the iPhone 16 or iPhone 17, which come with enhanced AI functions and longer software support.

The Importance of iOS Updates: iPhone 13 Pro Max and the Latest OS

 

Even though the iPhone 13 Pro Max still receives iOS updates in 2025, many expect that major update support will end within the next one to two years, as per Apple’s typical lifecycle. Once major OS updates stop, users may face issues with security patches and compatibility with newer apps requiring the latest iOS versions.

 

Tip: Check the latest iOS compatibility on MacRumors’ Buyer’s Guide or on Apple’s official site to better estimate your device’s lifespan.

 

Technology Gap: When AI Features Become the Standard

 

Phones released in 2025 — particularly iPhone 16 and 17 — are equipped with AI-powered features that enhance camera performance, voice recognition, and Siri’s intelligence. The A15 Bionic chip inside the iPhone 13 Pro Max has limited capability for advanced machine learning tasks, meaning users may not experience the full benefits of AI as with newer models.

 

This could be a key reason to consider an upgrade, especially if you rely on AI-driven apps or perform tasks like professional video editing.

Circular Economy and Selling to Refurbished Stores

 

Selling your old iPhone to a refurbished store has become increasingly popular in 2025. These shops typically restock, refurbish, and resell devices in international markets, offering higher prices for high-quality, original-condition phones.

 

In addition, supporting the circular economy is an eco-friendly choice that helps reduce electronic waste and extends product lifecycle.
