Official machine replacement is an after-sales benefit for fruit fans. If there is any problem, just replace it with a new one, and the National Bank machine is The one-year warranty period is recalculated. Hong Kong companies can also replace the machine with a new one in China, but the warranty period extends the previous warranty of the machine. However, this welfare policy is used as a loophole by scalpers. After a large number of machines insured by the Bank of China are recycled, most of them resort to various malfunction methods to obtain a brand new official replacement machine and sell it after the sale. This is also the case under the guarantee of the Bank of China. The main reason why used mobile phones can be sold for a good price.

The scalpers go to war, but not a blade of grass grows. It even got to the point where the number of people asking for new phones every day was more than the number of new phones Apple sold every day. Apple finally couldn't bear it anymore and decided that starting from November 2016, it would no longer implement the "replacement instead of repair" policy in China due to motherboard failures. The machines usually only replace the new motherboard or some accessories.

Under Apple's strict enforcement, the loopholes in after-sales replacements have been basically closed, so scalpers have inevitably opened a new era called the "official repair era."

However, after Apple’s strong technical support and strict factory inspection process, it is delivered to users. Generally, all functions are normal, and currently official repair machines are basically directly replaced with a brand new motherboard. As we all know, the motherboard is responsible for controlling everything. All accessories, as long as the motherboard is brand new, will be no different from a brand new machine.

Of course, a small number of official repair machines also have repaired motherboards, but Apple’s official repair technology should be more reassuring. Official repair machines also come with a warranty, usually Extend the previous warranty period of the machine. If the warranty period is less than three months, the three-month warranty will generally be defaulted.
