You bought your iPhone for full price. A year later, it’s worth a fraction of what you paid. Two years later, even less. This isn’t bad luck – it’s a pattern. And once you understand it, you can work with it instead of losing to it.
Every iPhone model follows a depreciation curve. Some drop fast and flatten out. Some hold value longer than others. A few surprise people by staying relevant well past their launch year. Knowing where your model sits on that curve is the difference between a good sale and a regrettable one.
This guide walks through how different iPhone models lose value, what drives the drop, and when you should actually sell – backed by real market behavior, not guesswork.
At CellCashr, we’ve seen thousands of iPhones come through Sell iPhone New Jersey, and the patterns are consistent. Here’s what the data tells us.
The First 30 Days: The Sharpest Drop You’ll Ever See
The moment you walk out of the Apple Store, your iPhone begins losing value. That’s not a figure of speech – it’s literally true. A sealed, brand-new iPhone from a third-party seller already trades at a discount compared to Apple’s retail price.
But the first real depreciation shock happens when the next model is announced.
Apple announces new iPhones every September. In the two to four weeks surrounding that announcement, the previous generation loses a significant chunk of its resale value – sometimes 20 to 35 percent almost overnight. Buyers who were willing to pay top dollar for your iPhone 15 in August suddenly want to wait and see what the 16 brings.
This is the single most predictable and avoidable value loss in the entire iPhone resale market.
- Sell in July or August – you’re ahead of the announcement wave
- Sell in October or November – you’ve absorbed the full announcement hit
- Sell in December or later – you’re competing with a market flooded with trade-ins from people who just upgraded
The first 30 days after a new launch is the worst possible time to sell the previous generation. If you’ve already missed that window, wait for the market to stabilize – usually 6 to 8 weeks after launch.
Standard Models vs. Pro Models: Very Different Depreciation Curves
Not all iPhones age the same way. The biggest split is between standard and Pro models – and most sellers don’t account for this.
Standard iPhone Models (Base and Plus)
Standard iPhones depreciate faster and more steeply than Pros. Here’s why:
- They’re priced lower to begin with, so the absolute dollar drop hits a floor faster
- They’re purchased in much higher volumes, which means the resale market is flooded with them
- They lack the camera and chip differentiators that keep Pro models relevant longer
- Buyers looking for a budget iPhone have many more options to choose from
A base model iPhone typically loses a large portion of its launch value within the first 12 months. By the time it’s two generations old, resale value has usually settled at a much lower level where it holds relatively steady for a while.
The window to sell a standard model at a strong price is narrow – ideally within the first 10 to 14 months of ownership, before the next generation is announced.
Pro and Pro Max Models: Slower Burn, Higher Floor
Pro models hold value better, for longer. The reasons are straightforward:
- They start at a higher price point, so the curve is less steep in percentage terms
- The camera systems, LiDAR, ProMotion display, and other Pro-exclusive features retain appeal among buyers who specifically want those capabilities
- They appeal to a more serious buyer segment – content creators, professionals, power users – who are willing to pay more for older Pro hardware over a newer base model
- Lower sales volumes mean less resale market saturation
An iPhone Pro from two years ago still commands a meaningful price on the secondary market, especially in 256GB and higher storage configurations. The same can’t be said for a two-year-old base model.
Bottom line for sellers: If you own a Pro or Pro Max, you have more flexibility on timing. If you own a base or Plus model, act sooner.
The Generation-by-Generation Breakdown
Let’s be specific about how different generations behave in the resale market today.
iPhone X Through iPhone 11 Series
These models are at a late stage in their resale lifecycle. They’re still functional, still supported on current iOS (though the X and XR are approaching end-of-support), but their market value has largely bottomed out.
The good news: the value is relatively stable at this point. It won’t drop much further. The bad news: it’s not going up either. If you’re holding one of these, sell now rather than waiting, because iOS support removal will trigger another drop when it happens.
The iPhone 11, in particular, holds its value better than the X or XS because it was sold in massive volumes, is still widely supported, and remains a capable daily driver for budget-conscious buyers.
iPhone 12 Series
The 12 series sits in an interesting position. It was the first 5G iPhone lineup, which kept demand stronger than previous generations at the same age. Buyers who want 5G on a budget still look here.
The 12 Pro and 12 Pro Max still fetch reasonable prices, especially in good condition with healthy batteries. Standard 12 and 12 Mini models have dropped more sharply – the Mini never found a large audience, which kept resale demand limited.
If you have a 12 Pro or 12 Pro Max in excellent condition, you’re still in a position to get meaningful value. Don’t wait another year.
iPhone 13 Series
This is currently one of the strongest value-to-age ratios in the resale market. The 13 series was a genuine performance leap, received strong reviews, and sold in high numbers – which means buyers know and trust the model.
The 13 Pro and 13 Pro Max still hold solid resale value. Battery life on the 13 series was a significant improvement over the 12, and buyers are aware of this.
If you’re planning to upgrade and you have a 13 series, the next 6 to 12 months are your best window before the 15’s successor pushes the 13 further down the curve.
iPhone 14 Series
The 14 base model was controversial at launch because it didn’t use the new A16 chip – Apple used the A15 from the 13 Pro in the base 14. Buyers in the resale market have figured this out. The base 14 doesn’t command the premium its price tag might suggest.
The 14 Pro and 14 Pro Max are a different story. They got the A16, the Dynamic Island, the 48MP main camera, and always-on display. These features keep the Pro models desirable, and resale value reflects that.
Sell a base 14 sooner rather than later. Hold a 14 Pro if you’re not in a rush – but don’t sleep on it past next summer.
iPhone 15 Series
The 15 series is still in its active depreciation window. Value has dropped from launch highs but hasn’t reached the stable floor yet. If you’re planning to sell a 15, the next few months before Apple’s 17 announcement are your best opportunity.
The 15 Pro and 15 Pro Max introduced titanium build quality and USB-C, both of which buyers notice and value. These will hold up better than the base 15 over the next 12 to 18 months.
What Accelerates Depreciation Beyond Normal Cycles
Some iPhones drop faster than they should because of factors that have nothing to do with age.
iOS Support Removal
When Apple drops a model from new iOS updates, that phone’s resale value takes a hit. Buyers don’t want to buy a phone that’s already running its last operating system. Watch Apple’s support cutoff announcements – they can trigger a value drop in a matter of weeks.
Widespread Reported Issues
If a model becomes known for a specific hardware or software problem – battery swelling, camera defects, signal issues – resale demand drops and prices follow. This has happened to specific models in the past and will happen again.
Major Carrier Promotions
When carriers offer heavy trade-in incentives to push a new model, the secondary market gets flooded with the previous generation. More supply, same demand, lower prices. CellCashr monitors these cycles so we can give you accurate timing advice when you come to SellIPhoneNJ.com.
Physical Damage
A cracked screen or compromised casing doesn’t just affect the sale price proportionally – it can push your phone into a lower condition tier entirely, which affects the price more than the damage itself would suggest.
The Depreciation Math Most Sellers Ignore
Here’s a practical way to think about it:
iPhones generally lose the most value in the first 12 to 18 months. After that, the curve flattens significantly. This means:
- Holding your phone from month 6 to month 12 costs you more in lost value than holding it from month 18 to month 24
- The “I’ll sell it when I upgrade” strategy often means you’ve already absorbed most of the depreciation
- The optimal sell window – if maximizing value is the goal – is before the next model launches, regardless of how long you’ve had the phone
Many sellers wait until their new phone arrives before listing the old one. By that point, the announcement has already hit, launch demand has already peaked, and they’re selling into a flooded market.
The smarter move: list your current phone before your new one arrives. Use the proceeds to offset the upgrade cost. This is exactly what CellCashr helps New Jersey sellers do at SellIPhoneNJ.com – quick, accurate quotes so you can time your sale without guessing.

Mini Models – A Special Case
iPhone Mini models deserve their own mention because they behave differently from every other line.
The 12 Mini and 13 Mini were commercially disappointing for Apple – sales were lower than expected. In the resale market, this cuts both ways. Lower supply means the market isn’t flooded. But lower demand means finding a buyer willing to pay a fair price takes longer.
Mini models also tend to have smaller batteries, which buyers check carefully. If your Mini’s battery health is below 85%, expect questions.
If you have a Mini, sell through a channel that actively reaches buyers who want compact phones. A local buyer like CellCashr who knows the NJ market is more likely to give you fair value than a national buyback site with a one-size-fits-all pricing algorithm.
FAQs
Which iPhone model holds its value the best?
Ans: Pro and Pro Max models consistently hold value better than base and Plus models. Within the current market, the 14 Pro Max and 15 Pro Max have the strongest resale value among recent generations.
When is the worst time to sell a used iPhone?
Ans: The two to four weeks immediately after Apple’s September launch event. The market is flooded with trade-ins and demand temporarily shifts toward the new models.
Does the color of my iPhone affect resale value?
Ans: Marginally. Some colors in certain models are more popular and sell faster, but the price difference is usually small. Condition and battery health matter far more.
How much value does an iPhone lose per year on average?
Ans: The first year is the steepest – often 20 to 40 percent of retail value depending on the model. Years two and three see slower, steadier drops. Pro models lose less percentage-wise in year one than base models.
Is it better to sell to CellCashr locally or use a national buyback site?
Ans: Local buyers like CellCashr at Sell iPhone NJ inspect the phone in person and don’t adjust the price after the fact. National mail-in programs build uncertainty margins into their offers and sometimes revise prices downward once the phone arrives. For most sellers, local is the better deal.
Final Word
iPhone depreciation follows real patterns – by model, by generation, by season, and by condition. Understanding those patterns doesn’t require being a tech expert. It just requires knowing when to act and who to sell to.
