First of all, the depreciation problem of iPhone is inseparable from the upgrade of the product. Since its birth, iPhone has undergone a series of version upgrades such as iPhone 3G, iPhone 4, iPhone 5, etc. Each upgrade will bring a certain degree of technical enhancements and improvements.At the same time, the original product value also gradually declines, resulting in depreciation problems.

Although this phenomenon cannot be completely eliminated, the corresponding treatment method also exists. First of all, in response to the depreciation problem mentioned above, consumers can choose a more comfortable mobile phone protective cover to avoid more damage and defects in the mobile phone and protect the integrity of the appearance of the mobile phone. Secondly, consumers can choose to upgrade their mobile phones after one or two years of use, so that they can enjoy the most cutting-edge mobile phone technology in a more timely manner, and they can also reasonably recycle their certain value before recycling the old phone. If you are really worried that your mobile phone will depreciate in the process, you can choose a more affordable and functional Chinese brand to achieve better cost performance.In summary, there is no doubt about the depreciation of the iPhone, but it does not affect its popularity in the market. Users can slow down the depreciation of iPhones through more careful purchase plans and protection measures, and upgrade mobile phones at any time according to market demand.
