According to data gathered by SellCell, the iPhone 14 models have lost more value than the iPhone 13 in the past year.

SellCell uses average trade-in values from over 40 vendors. The data shows that the iPhone 14 and iPhone 14 Plus are performing poorly in terms of value retention, depreciating twice as much as the iPhone 13 and iPhone 13 mini in the same 10 day period after launch. In the 10 days after launch, the standard iPhone 14 models lost more than twice as much as the iPhone 13 models.

The worst-performing model is the 512GB version of the phone. The 512GB iPhone 13 mini was Apple's fastest depreciating model, losing 29.8% of its value 10 days after it was released.

The aftermarket prices for the device show an expected depreciation of 38.6 percent, even though the device is not yet available. The market can better evaluate demand once the device is available.

The situation is not as bad for the iPhone 14 Pro Max. In the 10 days after launch, this is better than last year's Pro Max. The 512GB iPhone 14 Pro Max lost 18.2 percent of its value, but it was still the best-performing model. The iPhone 14 Pro and iPhone 14 Pro Max have the same depreciation rate as the iPhone 13 Pro and iPhone 13 Pro Max.

Multiple reports claim that there is low demand for the iPhone 14 and 14 Plus. Panel orders for the iPhone 14 are down 38 percent compared to the same time last year according to Ross Young. The panel orders for the iPhone 14 Pro Max are up 18 percent.

The demand for the two devices is "lackluster", with worse pre-order results than the previous generation of the device. He claimed that Apple's product segmentation strategy for standard models fails this year and that the company is not increasing production of the two devices. High demand continues for the iPhone 14 Pro and iPhone 14 Pro Max.
