The iPhone 13 Trade-In Reality Check
Time is of the essence. Right now, your iPhone 13’s trade-in value is holding steady, but there’s a hard deadline at the end of August.
Current trade-in offers for good-condition devices hover around $229—with the spectrum ranging from $200 for 128GB models up to $400 for those coveted 512GB versions. Third-party platforms like Sell Locked consistently edge out Apple’s official offers, while occasional carrier promotions briefly sweeten the deal.
But this window of opportunity is about to slam shut. Every September, Apple introduces its latest models and trade-in values for older iPhones drop in unison—this year, right after the iPhone 17 reveal.
Why September Spells Disaster for iPhone 13 Values
Historically, trade-in values plunge 10-20% in the weeks after a new iPhone announcement. The reason? In September, the market is flooded with used iPhones and every major trade-in source updates its payout algorithms almost immediately. Annual industry data confirms this pattern year after year.
Market flooding, shifting carrier promotions, and the looming sense of obsolescence combine to drive prices down. Even strong promotional offers end abruptly once the spotlight shifts to the new generation. As carrier trade-in guides and major forums advise, August is the sweet spot—by mid-September, you’re dealing with a far less lucrative landscape.
Your Last-Minute Action Plan for Maximum Payout
Lock in your trade-in no later than August 25th. Each day closer to September means less money in your pocket—this is the year’s most time-sensitive move for iPhone 13 sellers.
Always compare offers from Apple, your carrier, and leading buyback services. Carriers might tempt you with up to $270 for trade-ins, but third-party platforms have pushed values up to $400 for premium models. For the best deal, prep your device: back up data, perform a factory reset, clean the exterior, and have it unlocked if possible.
Finally, keep an eye out for fleeting promotions. It’s not unusual for short-term bonuses to offer $10-30 extra. Act quickly—by the time the iPhone 17 reveal hits, these promos will evaporate overnight.
Storage Capacity: Your Hidden Value Multiplier
Storage size matters—a lot. The 512GB iPhone 13 routinely lands $100+ above its 128GB sibling, making high-capacity devices a goldmine for owners who upgrade early. Buyers pay a premium for plenty of space, and every extra gigabyte boosts value.
256GB versions claim a lucrative middle ground, averaging $30-50 more than base models. Also, an unlocked device commands $20-30 higher offers—if your phone is paid off, unlock it through your carrier’s portal prior to sale.
Device Condition: The Make-or-Break Factor
Your iPhone’s cosmetic and functional condition can swing trade-in invitations by $50-100. “Mint” means pristine—no scratches, all functions perfect, battery above 85%. Even “excellent” (minor wear, battery at least 80%) keeps you close to top-tier returns.
Phones with visible wear, dings, or battery health below 80% tumble into “good” condition, often knocking 15-30% off the payout. The lesson? Spend 20 minutes cleaning and prepping for a big difference on appraisal day. Details here.

Carrier vs. Third-Party: Where to Get the Best Deal
Should you stick with your carrier or sell to a buyback company? Carrier trade-ins can be lucrative—especially when timed with an upgrade—but require a new plan or device purchase. Some programs run limited-time promotions that beat pure resale value.
Buyback businesses like Sell Locked, BuyBack Boss, or GadgetGone typically offer no-strings-attached cash payments, while Apple’s program grants versatile store credit. In late August, check at least three sources—carriers, buybacks, and Apple—to capitalize on the best available offer.
Special Situations: Damaged, Locked, or Financed Phones
Don’t rule out trade-in if your iPhone 13 is cracked, battery-weary, or still carrier-locked—you still have options. Minor screen cracks mean a $50-100 penalty, but some carriers offer promotions even on lightly damaged phones. A battery below 80% can mean a steeper drop; it’s sometimes worth the expense to replace in advance.
Carrier-locked or financed phones restrict your choices—always factor in payoffs or unlocking opportunities to unlock better deals.
The iPhone 17 Factor: What’s Coming Next
Apple’s September launch reshuffles the used iPhone market overnight. The iPhone 13 goes from “last-gen” to “several years old” the moment the iPhone 17 is announced. Buyer sentiment shifts and trade-in prices drop within hours, not weeks. Industry sources and marketplaces confirm this repeated, lightning-fast transition each September.
If you want to get ahead of the curve, trade in before the hype sets in. Waiting ensures you’ll see your payout fall—history has proven this pattern is reliable.
Comparing Today’s Top Trade-In Programs
As of late August, Sell Locked leads with payouts up to $400 for top-spec devices. BuyBack Boss and GadgetGone offer $240-$277, while Apple’s rock-solid program maxes out at $250. Carriers sometimes match or beat these numbers during rare promotions, often requiring a new activation. Stay alert for short-term deals.
To secure the best price, get instant quotes from multiple sources and act decisively before September rolls around.
Preparation Checklist: Getting Your iPhone 13 Ready
This five-step checklist ensures maximum payout:
- Back up data using iCloud or iTunes and note 2FA/authentication settings.
- Sign out of iCloud, iTunes, and all accounts; double-check Find My iPhone is disabled.
- Factory reset: Settings > General > Reset > Erase All Content and Settings.
- Clean every surface and port; remove all cases or screen protectors.
- Gather original box, cables, and documentation—these sometimes net a bonus.
Test all buttons, Face ID, and cameras. Declare any issues accurately for a smooth transaction. Here’s a detailed guide if you’re not sure what to check.
Understanding the September Value Drop
The annual 10-20% iPhone value drop isn’t hypothetical—it’s well-documented. Each fall, resale prices for prior models hit their lowest mark just days after Apple’s keynote. History from trade-in trackers show the iPhone 12 and iPhone 11 both followed this pattern.
It’s tempting to wait, but recoveries take months. By October, older iPhones stay locked into the new “normal” price until next year’s trade-in cycle starts.
Alternative Strategies: Beyond Traditional Trade-In
Not satisfied with trade-in offers? Try these alternatives: You can sell privately on Facebook Marketplace or eBay—often earning up to 20% more, but you’ll invest extra time and effort (and take on some risk). Here’s how to do it right.
Carrier upgrade programs might package in accessories or bill credits worth more than a pure trade-in. Kiosks such as ecoATM offer instant cash, though their rates are typically lower. Finally, if the cash value isn’t enough to move you, keeping your iPhone 13 as a backup is always a sensible fallback.
Your iPhone 13’s trade-in value could drop 15-20% after Sept, like clockwork. Now’s the window for the top payout—jump on those promos before launch week.

Frequently Asked Questions
How quickly do trade-in values drop after new iPhone announcements?
Values usually dip within 24-48 hours of Apple’s keynote—expect a 10-15% immediate drop and another 5-10% over the next month as more devices flood the market.
Should I repair my iPhone 13 before trading it in?
It depends on cost versus reward—screen repairs are often worth it, while new batteries might not be. Always get both repair and trade-in value quotes to make an informed decision.
Can I trade in a carrier-locked iPhone 13?
Yes, but mainly through your own carrier unless the phone is unlocked. Unlocked models earn higher offers from buyback companies and are easier to sell elsewhere.
What happens if my trade-in evaluation comes back lower than quoted?
Most reputable buyback sites let you reject the revised offer and get your device mailed back for free. Always review terms before you ship your iPhone 13.
Are carrier trade-in promotions worth the hassle?
If you’re already planning to upgrade and remain with the carrier, promo offers can be the most lucrative. Weigh device requirements and plan changes before committing.
Your Two-Week Window Starts Now
The countdown is on. If you want top dollar for your iPhone 13, you have until the end of August 2025 to take action before the inevitable September price drop.
Compare multiple offers, prep your phone, and make your move—those who act now will come out far ahead of those who wait for “one more announcement.”
