The September Cliff: Why Your iPhone 15 Value Is About to Plummet
Every September, iPhone owners face a value “cliff”—your device is worth hundreds one week, then rapidly nosedives the next. With the iPhone 16 launch on the horizon, trade-in values for iPhone 15 are poised to drop 10-20%—or more—practically overnight. That’s a potential loss of $100+ for sitting on the fence.
Think of it like the last concert ticket before showtime: if you wait, you’ll be giving your phone away. Industry data confirms that the best time to trade in is late July to mid-August, right before Apple’s big event. Don’t let FOMO cost you real cash.
Current iPhone 15 Trade-In Values: The Numbers That Matter
As of August 2025, here’s what leading platforms are offering for an iPhone 15 in good to excellent condition:
- Standard iPhone 15 (128GB): $363.50 average, up to $546 at buyback services
- Apple’s Official Trade-In Values: Pro Max $630–$650, Pro $500–$600, Standard $400–$500 [source]
- Third-Party Buyback: Up to $541 for a 512GB iPhone 15 [details]
Don’t be fooled by today’s numbers—Apple typically adjusts trade-in values downward before every major unveiling. Today’s “fair offer” is tomorrow’s missed opportunity.
Storage Size Matters: Why Bigger Means Better Payouts
If your iPhone 15 has extra storage (256GB/512GB), your device is worth more to buyers—and you’ll see $50–$100 extra at trade-in. It’s like having a house with a bigger garage: everyone wants the extra space. The resale premium only gets more noticeable over time.
Platform Showdown: Where to Get the Most Bang for Your Buck
- Apple Trade-In: Safe, quick, and pays $400–$500 (store credit/gift card). Great for Apple shoppers, less so if you need cash. [details]
- Third-Party Buybacks: Competitive, cash-based offers (up to $546) via companies like BankMyCell and BuyBack Boss. [see guide]
- Private Sales (Swappa, eBay, Facebook Marketplace): Highest payout potential ($400–$550+), but more hassle and risk.
- GizmoGrind: A “just right” blend: competitive payouts, lightning-fast quotes, and pro-level convenience.
Timing Is Everything: The August Action Plan
Late July to mid-August is your golden window. After the iPhone 16 announcement, your iPhone 15’s value will plummet. Industry stats show a 10–20% drop within weeks [see data]. Avoid the September rush; trade in now for top dollar.
Condition Is King: Preparing Your iPhone 15 for Maximum Value
- Excellent (like-new): Highest payout. Cared-for, no visible blemishes.
- Good: Minor wear but fully functional.
- Fair: Noticeable wear or minor flaws but working.
Boost your value with simple prep:
- Factory reset after backing up your data first!
- Clean it thoroughly—microfiber magic.
- Gather original box and accessories (adds value!).
- Make sure it’s unlocked from your carrier.
Storage Premium: Why Your 512GB Model Is Golden
Higher capacity iPhones keep their value—often $50–$100 more than 128GB models. Buyers want storage, and that demand lifts resale prices. If you bought bigger, you win big now. [source]
Platform Comparison: The Ultimate Showdown
- Apple vs. Third-Party: Apple = store credit convenience; third-party = more cash.
- Private Sale vs. Buyback: Private sale can bring up to $50 more but takes effort and risks; buyback = fast, safe, and reliable.
- GizmoGrind: Your “smart seller” move—competitive offers, ease, support, and green-focused.
Special Considerations: The Fine Print That Matters
- Carrier Locks: Always unlock your phone for better value. Instructions usually found free via your carrier.
- iCloud Lock: Don’t forget to disable Find My iPhone—a locked device is unsellable.
- Water Damage: Even minor damage is a deal-breaker for most services.
The Environmental Angle: Feel Good About Your Trade-In
Trading in through responsible firms like GizmoGrind ensures your phone is refurbished for a second life or recycled ethically. It’s the win-win-win: you get cash, someone else gets a quality phone, and the planet wins too.
Quick Sale Tips: Your Speed-Selling Toolkit
- Challenge: Prep your phone to sell in 24 hours—
- Back up your data
- Sign out, factory reset, and clean
- Take photos of condition
- Get 3–4 quotes and pick your winner
- Extra Docs: Receipt, proof it’s paid off, original accessories—these boost value.
- Red Flags: Avoid offers that require upfront payment, look suspicious, or lack business credentials/tracking.
Model-Specific Values: Know Your Phone’s Worth
- iPhone 15 Pro Max: $630–$650 (top tier value)
- iPhone 15 Pro: $500–$600, high resale
- iPhone 15 (standard): $400–$500, still strong
- iPhone 15 Plus: Between standard and Pro, thanks to screen size and demand
Seasonal Patterns: Why September Is the Danger Zone
The value cycle is clockwork predictable:
- July–August: Stable, high value—smart sellers act now
- September: The drop. Apple’s event triggers mass sell-offs and rapid price falls.
- October–December: Flooded market, prices hit yearly low
- January–March: Small recovery, but never returns to summer highs.

Frequently Asked Questions
How quickly do iPhone 15 trade-in values fall after the iPhone 16 launch?
Values typically drop 10-20% (often $50-$100 or more) within weeks of Apple’s September announcement. The fastest drop happens in the first 2–4 weeks as the market floods with old models.
Where do I get the most cash for my iPhone 15 in 2025?
Third-party buyback services (like GizmoGrind or BankMyCell) usually pay more than Apple’s program. Private sales may pay the most, but require more time and effort.
What makes my iPhone 15 worth more at trade-in?
Storage size (256GB/512GB), excellent condition, unlocked status, and including the original box/accessories can increase value significantly.
Can I trade in a damaged or water-damaged iPhone 15?
Most platforms, including GizmoGrind, do not accept water-damaged devices. Minor wear is fine, but phones must be fully functional.
How do I prepare my iPhone for trade-in?
Back up your data, factory reset, clean it, unlock from carrier, and sign out of iCloud/disable Find My iPhone.
What if I wait until October or later to sell?
Expect much lower offers. Most sellers upgrade in September, overwhelming the market and making your phone “old news.”
