Apple releases new iPhones every September. That single event is the biggest driver of used iPhone prices — and knowing how to time your sale around it can net you an extra $50–$150.
What Happens to iPhone Prices Around September
iPhone resale prices follow a predictable curve every year:
- June–August: Prices slowly decline as people anticipate the new release
- September (announcement): Prices drop 10–20% within days of Apple's event
- September–October (new model ships): Prices continue falling as new devices arrive and trade-ins flood the market
- October–November: Prices stabilize at their new lower floor
- Holiday season: Minor uptick in demand, slight price recovery
Real Example: iPhone 14 Pro Max Value Over Time
| Time Period | TechITAZ Buy Price (256GB) | Change |
|---|---|---|
| June 2023 (pre-announcement) | ~$580 | — |
| September 2023 (iPhone 15 launched) | ~$480 | -$100 |
| January 2024 | ~$420 | -$60 more |
| June 2024 | ~$370 | -$50 more |
| September 2024 (iPhone 16 launched) | ~$340 | -$30 more |
The Simple Rule
Sell before September, not after. The worst time to sell is in the 3-4 weeks after a new iPhone launches — that's when the market is flooded with trade-ins and prices are at their lowest.
The best window is typically June through mid-August. You capture the last few months of peak value before the pre-announcement decline.
💡 If you've already missed the window, sell now rather than waiting for "next year." Prices continue declining — the longer you wait, the less you get.
What About Mid-Cycle Releases?
Apple also releases new iPads and MacBooks throughout the year. The same principle applies — sell before the announcement, not after. Watch Apple's event calendar at apple.com/apple-events.
