iPhone 15 Pro Max 與新一代 iPhone 17 升級換購概念圖
對於資深的果粉來說，「兩年一換」是公認 CP 值最高的升級節奏。時間來到 2026 年，隨著新一代 iPhone 17 即將登場，手持 iPhone 15 Pro Max 的用戶正是這波換機潮的主力軍。然而，一支旗艦機動輒四、五萬元，如何將舊手機的價值最大化，成為了省錢的關鍵。今天我們就來比較不同的台中 iPhone 舊換新管道，幫您精打細算。
For veteran Apple fans, “changing every two years” is recognized as the upgrade rhythm with the highest cost-performance ratio. As we reach 2026, with the upcoming debut of the new iPhone 17, users holding the iPhone 15 Pro Max are the main force of this wave of replacements. However, a flagship phone easily costs forty to fifty thousand dollars; maximizing the value of the old phone has become the key to saving money. Today, we will compare different Taichung iPhone Trade-in channels to help you calculate carefully.
手機折舊曲線顯示，旗艦機在上市後的第 24 個月（即兩年期滿）通常還保有約 50%~55% 的殘值。
iPhone 15 Pro Max 作為首款搭載鈦金屬邊框與 5 倍光學變焦的機種，在二手市場依然非常搶手。若您等到 iPhone 17 正式發售後才賣，屆時市場將湧入大量同型號拋售潮，價格恐會瞬間下跌 10% 以上。因此，在「新機發表前的空窗期」進行估價，是鎖住高價的秘訣。
The phone depreciation curve shows that flagship phones usually retain about 50% to 55% of their residual value in the 24th month after listing (i.e., the expiration of the two-year period).
As the first model equipped with a titanium frame and 5x optical zoom, the iPhone 15 Pro Max is still very popular in the second-hand market. If you wait until the iPhone 17 is officially released to sell, the market will be flooded with a large wave of selling of the same model, and the price may drop by more than 10% instantly. Therefore, conducting a valuation during the “window period before the new phone launch” is the secret to locking in a high price.
許多人為了方便，會直接選擇 Apple 官網的 Trade-in 方案。但若您仔細進行Apple Trade-in 比較，會發現兩大缺點：
第一，官方估價偏低：為了確保利潤，官方回收價通常低於市價 15% 至 20%。
第二，只能換禮品卡：官方僅提供折抵金（Gift Card），無法換取現金。這意味著您必須被綁定在 Apple 體系內消費。
For convenience, many people directly choose the Trade-in program on the official Apple website. But if you carefully do an Apple Trade-in comparison, you will find two major disadvantages:
First, official valuation is low: To ensure profit, the official buyback price is usually 15% to 20% lower than the market price.
Second, gift cards only: The official only offers credit (Gift Card) and cannot be exchanged for cash. This means you must be tied to the Apple ecosystem for consumption.
最靈活的做法，是找一家信譽良好的收購店（如青蘋果 3C），將您的 iPhone 15 Pro Max 換成「現金」。
拿到現金後，您不僅可以用來購買 iPhone 17，剩下的錢還能去買喜歡的手機殼、保護貼，甚至吃一頓大餐。這種「現金為王」的策略，讓您的資金運用不再受限，且通常能換到比官方更高的金額。
The most flexible approach is to find a reputable buyback shop (such as GreenApple 3C) and exchange your iPhone 15 Pro Max for “cash”.
After getting the cash, you can not only use it to buy the iPhone 17, but the remaining money can also be used to buy your favorite phone case, screen protector, or even have a big meal. This “cash is king” strategy allows your fund usage to be unrestricted, and usually exchanges for a higher amount than the official offer.
