Navigating the Dynamic iPhone Resale Market
The iPhone market is always evolving, and the years 2025-2026 are no exception, marking significant shifts driven by technological advancements and changing user behavior. Understanding which models are “คนขายเยอะที่สุด” (most sold or traded) is crucial for anyone looking to upgrade or sell their device strategically in the secondary market.
This period is characterized by new innovations like advanced on-device AI capabilities and groundbreaking new form factors, all of which heavily influence device lifecycles and user upgrade cycles. This article aims to identify the top iPhone models people are actively selling and provide actionable insights to help you maximize their value.
The Shifting Landscape: Key Trends Driving iPhone Upgrades & Sales (2025-2026)
The 2025 “Super-Cycle” & New Model Appeal
The year 2025 was a “super-cycle” for Apple, with shipments projected to hit approximately 247 million units, marking a significant year-over-year increase. This was largely driven by two key launches:
- The much-anticipated iPhone 16e, launched in early 2025 at around $599, served as a major entry point into Apple’s new AI ecosystem, featuring the A18 chip and 8GB of RAM to support “Apple Intelligence.”
- The transformative iPhone 17 series, launched in September 2025, saw the introduction of 120Hz ProMotion displays on base iPhone 17 models for the first time, a major incentive for many users to upgrade from older devices. The base iPhone 17 itself became a standout performer during the holiday season, with initial sales 16% higher than the iPhone 16 series launch.
The AI Revolution with “Apple Intelligence”
On-device AI capabilities, branded as “Apple Intelligence,” have become a primary reason for users to upgrade. By the end of 2025, over 30% of all shipped smartphones were expected to be GenAI-capable, featuring dedicated Neural Processing Units (NPUs). Apple is projected to take the top position in the GenAI smartphone market by 2026, leveraging its integrated AI across its massive user base. Consequently, older iPhone models lacking these integrated AI features increasingly become prime candidates for selling.
New Form Factors & Premiumization
Innovation in design continues to drive upgrades. The ultra-thin iPhone 17 Air (5.5mm–6.0mm) was introduced in 2025, targeting users seeking a premium, lightweight design. Looking ahead to late 2026, the highly anticipated Foldable iPhone is expected to debut with a price tag above $2,000, further solidifying Apple’s presence in the ultra-premium segment. These groundbreaking innovations encourage early adopters and premium users to sell their current high-end models quickly to always have the latest technology.
The 2026 Market Correction: Memory Crisis & Price Hikes
While 2025 saw significant growth, 2026 is predicted to face a slight decline in new unit shipments (down 1–2%) due to a global memory component shortage and rising Average Selling Price (ASP). ASPs are forecast to rise by 14% in 2026, potentially hitting a record high of $523. This structural downturn could lead to a significant 12% drop in global smartphone shipments, impacting budget brands. For the used market, this trend could make selling existing models at good prices even more attractive, as new devices become scarcer and more expensive.
The “Most Sold” iPhones in 2025-2026: A Deep Dive into Trade-in & Resale Patterns
In 2025-2026, the market for used and trade-in iPhones is exceptionally active. Here’s a breakdown of the models that people are most frequently selling, categorized by the driving factors:
iPhone 13: The Legacy Powerhouse Nearing its Upgrade Peak
- Why people are selling: The iPhone 13 possesses one of the largest active user bases, making it the most *widely used* iPhone model for much of 2025. Now 4-5 years old, it’s entering its typical upgrade cycle as users seek newer features, especially “Apple Intelligence.”
- Seller insight: The iPhone 13 still holds good initial resale value, but expect a rapid decline as it ages further. Selling now maximizes returns before its value drops significantly by 2027.
iPhone 14: The Smart Upgrade Sweet Spot
- Why people are selling: After the iPhone 17 launch in 2025, the market price of the iPhone 14 became highly attractive, often in the range of $215-$250. This offered a compelling upgrade path to the iPhone 16/17 series, which brought significant feature improvements like “Apple Intelligence” and 120Hz displays on base models.
- Seller insight: There is high trade-in demand for the iPhone 14, presenting a strong opportunity for a smooth transition to newer technology, as buyers are looking for good value.
iPhone 17 Pro Max: The Early Adopter’s Rapid Turnover
- Why people are selling: Ultra-premium users frequently upgrade to the absolute latest models, often anticipating devices like the iPhone 18 or the Foldable iPhone. Data from early 2026 indicated the iPhone 17 Pro Max saw surprisingly high trade-in rates (around 11.5% of total trades). These users prioritize preserving high resale value by selling soon after purchase, sometimes after only a few months of use.
- Seller insight: For such high-end models, maximize value quickly after a short period of use, tapping into peak demand for high-end second-hand devices.
iPhone XS, XR, & iPhone 11: The End-of-Life Exodus
- Why people are selling:
- iPhone XS/XR: Software support is ending (iOS 18 was likely their last major update), leading to looming app incompatibility issues and a less secure user experience in 2025-2026.
- iPhone 11: Despite still being functional, it lacks 5G connectivity, which has become a crucial factor for modern mobile internet usage. This makes it a prime candidate for selling or discarding for users seeking faster speeds.
- Seller insight: These models should be sold as budget devices or for parts; their market value is dropping rapidly. Act swiftly if you still wish to get any value from them.
iPhone 15 Pro / 15 Pro Max: High Demand in the Quality Used Market
- Why people are selling: Many users of the iPhone 15 Pro/Pro Max are upgrading to the newer iPhone 17 Pro/Pro Max. However, these 15 Pro series models are still highly desirable in the quality used market due to features like USB-C, a titanium design, and powerful performance. They represent excellent value for buyers who want premium features at a more accessible price point.
- Seller insight: These models command excellent resale value due to strong demand from buyers. If you have one in good condition, you can expect a very competitive offer.
