Friends who often assemble their own computers have discovered a problem. In the second-hand market, mobile phones depreciate much faster than computer accessories. A graphics card may be sold for 3,299 yuan, and the price may rise a lot after a while, unless a new model is released, but even if a new model is released, the price of the graphics card will not drop much, and mobile phones will see a very obvious price reduction after a while. Why is this?
In the past 10 years, all related supporting industries in the smartphone industry have been updated very quickly, and the upgrade rate of each generation is also very large, which has accelerated the "speed of depreciation". In fact, another point is that the parts of the computer can be reused. If the memory module is not enough, add more, the hard disk will be added if it is full, and the screen will be replaced if it is not working. There is no special reason to buy a new computer. It is all about replacing individual parts. But mobile phones are not good. If the hard disk is full, you have to consider buying a new phone. If the screen is broken, you have to buy a new phone. If the system freezes, you have to buy a new phone. If the running memory is small, you have to buy a new phone.

The public’s demand for computers has not increased significantly, and computers are basically sufficient. However, mobile apps are deliberately negatively optimized to slow down and jam your phone, stuffing all kinds of things into them, and having nonsensical functions that make you have to change them, and you cannot just cancel the version. The irreplaceability of the product also determines the speed of depreciation. Mobile phones and computers that are highly irreplaceable will naturally depreciate slowly, and those with many similar products that can be replaced will naturally depreciate faster.

Before buying electronic products, you must first consider your own usage needs. It is best to buy them for practical purposes, so as not to worry about the value retention rate and add worries.
