In less than 3 years, the iPhone 15 has lost over 60% of its value. And with the new iPhone 18 launch just months away, the value is only going to drop harder.
Not too long ago, the iPhone 15 was Apple’s latest and greatest with a huge price tag, but as is natural, depreciation set in, leaving the iPhone 15 a fraction of its original value.
Now in 2026, many owners are asking, “Should I sell my iPhone 15 now or wait?” With newer iPhones out and value steadily dropping, waiting too long could cost you real money.
In this article, I’ll break down what the iPhone 15 is worth right now, what’s driving its value down, and most importantly, whether 2026 is the right time to trade it in or sell it for cash.
How Much Is the iPhone 15 Worth in 2026?
Based on current market data at the time of writing, the resale value/trade-in value of a 128GB iPhone 15 in excellent condition ranges around $290 and around $250 for one in good/fair condition.
The 256GB iPhone 15 in excellent condition currently has a resale value of around $320, and $300 for iPhone 15s in fair/good condition.
Lastly, the highest tier, a 512GB iPhone 15, currently sells for around $360 and $340 for excellent and good/fair condition devices.
Current vs. launch price
If we take a look at the launch price of this device, we can see just how much value it has lost in less than 3 years.
| Storage | Launch Price | Current Value | Depreciation |
| 128GB | $799 | ~$290 | ~63% |
| 256GB | ~$899 | ~$320 | ~64% |
| 512GB | ~$1,099 | ~$360 | ~67% |
This means the iPhone 15 has already lost over 60% of its value in just about 2–3 years, which is typical for non-Pro iPhones but still a significant drop. With the iPhone 18 series release less than 5 months away, the iPhone 15’s value will only drop harder and faster. It could lose another $100 in value.
What’s Driving the iPhone 15’s Value Down?
-
Natural depreciation curve after 2-3 years.
Most smartphones lose the bulk of their value in the first three years. The iPhone 15 is right in that window, and the slide doesn’t slow down from here.
-
Impact of newer models (iPhone 16, 17, etc.).
Every new iPhone release shifts buyer attention and pulls demand away from older devices. With the iPhone 18 on the horizon, that pressure is about to increase.
-
Heavier apps, iOS updates, and performance perception.
As software demands grow, older hardware starts to feel slower even when nothing has technically changed. That perception alone drives buyers toward newer devices and pushes older ones down in value.
-
Battery health and hardware aging.
A degraded battery directly affects your offer on most platforms. The longer you wait, the more charge cycles stack up and the lower your condition rating gets.
-
Market saturation (more sellers = lower prices).
When a new iPhone drops, the secondary market gets flooded with last-gen devices. More supply with the same demand means lower prices across the board.
Trade-In vs. Selling: What Gets You More Money?
Carrier Trade-Ins (Convenience vs. Lower Payouts)
Carrier trade-ins are the most convenient option. You hand over your phone, get a discount on your next device, and move on. No shipping, no listings, no back-and-forth with strangers.
But that convenience comes at a cost. Offers are almost always tied to bill credits spread over 24 to 36 months, which means you only see the value if you stay on the contract (which includes their selected mobile data plan) and complete the term.
The actual payout tends to fall well below what your phone is worth on the open market, plus you’ll end up spending more overall. If maximum cash is the goal, carriers are rarely the right move. Our article on whether carrier deals are still worth it covers this in more detail, including how much a carrier trade-in ends up costing.
Retail Programs (Store Credit vs. Cash Problem)
Retail trade-in programs sit somewhere in the middle. You’ll generally get a slightly better offer than a carrier, but the gap is smaller than most people expect. The bigger issue is how you get paid: most retail programs pay in store credit, not cash. That limits what you can actually do with the value you’re getting and locks you into buying from that store specifically.
Best for people who already planned to shop there. Less useful if you want flexible, spendable money.
Online Buyback Platforms (Higher Payouts, Faster Cash)
This is where the math starts working in your favor. Online buyback platforms price offers based on real market demand, which typically puts them ahead of both carriers and retail programs. Payment is usually fast, often within a few days of receiving your device (a select few, like The Whiz Cells, send payment in 1 business day), and there are no long-term commitments attached to the deal. Plus, online buybacks are usually as convenient as carrier and retail programs.
Best for people who want the most money when selling their iPhone with the least hassle.
Private Selling (Highest Value, More Stress/Risk)
Selling directly through a marketplace or social platform has the potential to fetch you more money for your iPhone.
The tradeoff is real, though. You’ll deal with lowball offers, no-shows, and the occasional scam attempt. Shipping adds another layer of friction, and even local meetups take time to coordinate while being incredibly risky. Then, depending on which platform you use, fees can eat into your money.
Best for squeezing out maximum value, but takes much more effort without the guarantee of a better deal. So, it’s not worth it if your time or peace of mind is the priority.
| Platform | iPhone 15 128GB Good Condition | iPhone 15 512GB Excellent Condition |
| Carrier(T-Mobile) | $210 | $240 |
| Apple Trade In | Unknown | $310 |
| Private Selling(Swappa) | $380 | $520 |
| Online BuyBack(The Whiz Cells) | $265 | $371 |
Note: Apple Trade In does not ask for storage capacity when generating an online estimate, so the quoted value may not accurately reflect the exact storage variant of your iPhone.
Is 2026 the Right Time to Sell Your iPhone 15?
Whether or not now is the right time to sell your iPhone 15 depends on a number of things.
Sell Your iPhone 15 Now If:
- You plan to upgrade soon; your iPhone 15 can finance part of your upgrade.
- Your battery health is declining.
- You want to get the most value for your iPhone 15 before it declines further.
Hold If:
- The phone still performs well for your needs.
- You’re not upgrading anytime soon.
How Much Value Will The iPhone 15 Lose If You Wait?
Based on historical depreciation trends, over the next 12 months, the iPhone 15 will lose around 20% to 30% of its value. In other words, expect the resale value of the iPhone 15 to drop to around $250. The same device you spent $800 on just a few years ago.
Best Time of Year to Sell Your iPhone
Now
Your phone starts losing value the moment you unbox it and continually depreciates. So the best time to sell your iPhone 15 is NOW because the more time passes, the more value your device loses. If you truly want to get the most value when selling your iPhone 15, then sell it now (as soon as possible). Then again, selling now isn’t a realistic option for everybody, so the next best time to sell your iPhone 15 is…
Before The New iPhone Launch
With the hype and buzz of every new iPhone launch comes the steep downfall of older iPhones’ resale value. So every year, the window between Apple’s announcement and the actual release date is your next best opportunity to sell. Once the new model is official, buyers shift their attention, and sellers flood the market with last-gen devices. Supply spikes, demand drops, and prices follow. For a full breakdown of every selling window across the year, check out the Best Times To Sell an iPhone.
Tips to Maximize Your iPhone 15 Trade-In Value
- Keep battery health above key thresholds; 80% battery health.
- Maintain physical condition (screen, body)
- Include original accessories/box, if possible.
- Factory reset + proper listing strategy

If getting the most from your iPhone 15 is the priority, sooner is the safer bet. Values will keep sliding, especially as the next iPhone cycle gets closer.

A declining battery makes the case even stronger since the condition affects your payout directly.

Is a trade-in better than selling an iPhone?

Among buyback platforms, Whiz Cells pays competitively and sends payment within one business day of receiving your device.
What to do before trading in your iPhone?
Back up your data, turn off Find My iPhone, and sign out of your Apple ID. Do a factory reset to wipe the device clean. Check your battery health since it directly affects your offer.
