隨著 2026 年 Apple 秋季發表會的臨近，iPhone 17 系列的規格傳聞已甚囂塵上。對於持有舊款 iPhone 的用戶而言，最關心的莫過於手中的裝置還剩多少價值。根據 台中青蘋果3C 的市場大數據監測，每當新一代 iPhone 上市前後，二手市場皆會出現顯著的價格波動。本文將深入剖析 iPhone 17 上市後的舊機跌幅趨勢。
As the 2026 Apple Autumn Event approaches, rumors about the iPhone 17 series specifications are rampant. For users holding older iPhone models, the biggest concern is how much value their device retains. According to market big data monitoring by Taichung GreenApple 3C, significantly price fluctuations occur in the second-hand market whenever a new generation of iPhone is launched. This article will deeply analyze the depreciation trend of older models after the release of the iPhone 17.
iPhone 17 上市效應：舊機跌幅預測 (The Launch Effect)
歷史數據顯示，在新款 iPhone 正式發售的前一個月，舊款機型的回收價格平均會下跌 15% 至 20%。這是因為大量「早鳥換機族」會在此時拋售舊機，導致市場供過於求。特別是上一代的旗艦機型（如 iPhone 16 Pro Max），其價格敏感度最高。
Historical data shows that in the month before the official release of the new iPhone, the buyback price of older models drops by an average of 15% to 20%. This is because a large number of “early bird upgraders” sell their old phones at this time, leading to an oversupply in the market. In particular, the previous generation flagship models (such as the iPhone 16 Pro Max) have the highest price sensitivity.
影響回收價格的三大關鍵因素 (Key Factors)
除了新機上市的時間點外，決定您手中 iPhone 最終回收價的因素主要有三點：電池健康度、外觀保存狀況以及盒裝配件的完整性。專業的市場分析指出，電池健康度低於 80% 的手機，其折舊幅度會比正常二手機多出 5% 至 10%。
In addition to the timing of the new release, three main factors determine the final buyback price of your iPhone: battery health, physical condition, and the completeness of the box and accessories. Professional market analysis points out that phones with battery health below 80% depreciate 5% to 10% more than normal second-hand phones.
- 電池健康度 (Battery Health)：80% 為重要分水嶺，建議在健康度過低前脫手。
- 外觀等級 (Physical Condition)：邊框刮痕與螢幕鍍膜狀況直接影響分級（Grade A/B/C）。
- 容量規格 (Storage)：大容量版本 (512GB/1TB) 的保值率通常優於入門容量 (128GB)。
最佳脫手時機點分析 (Best Time to Sell)
如果您計畫升級 iPhone 17，我們強烈建議在「發表會前兩週」進行估價與出售。此時二手商為了備戰新機上市，通常仍願意以較高的行情收購優質庫存。一旦新機正式開賣，官方 Trade-in 價格調整，市場行情將會出現斷崖式下跌。
If you plan to upgrade to the iPhone 17, we strongly recommend valuing and selling your device “two weeks before the launch event”. At this time, second-hand dealers are usually still willing to buy high-quality inventory at higher market rates to prepare for the new release. Once the new phone officially goes on sale and the official Trade-in prices are adjusted, the market trend will experience a cliff-like drop.
