Because the price of iphone13 has been reduced recently, netizens bought a new iphone13pro of 99. After checking the machine, they found that it was a capacity expansion machine. After the release of

1iphone14, the price of iPhone13 has indeed been reduced a lot. In addition, 13 has been released for a year, and even the second-hand phones are mostly of better quality. As a result, I never expected that the iPhone13pro bought by netizens was actually an expansion machine. It was originally 256g of memory, but it was expanded to 512g.

Size expansion machines like this have two disadvantages, one is the price. You should know that the price difference between iphone 13 pro's 256G and 512G is more than 1,000 yuan, but the cost of expanding the capacity of the machine is not high. Therefore, some merchants will expand the capacity of small-capacity iPhones into large capacity and then sell them at large-capacity prices.

, on the other hand, is quality. The expansion requires removing the hard disk of the machine, heating the motherboard, and the process of high-temperature heating may affect CPU, which has relatively high technical requirements for the master. If the installation is not good, the phone may become impatient with falling and may easily have black screens. In addition, the waterproofing of the disassembled iPhone will be greatly discounted and the recycling price will be reduced.

So, when you buy a second-hand iPhone, it is best to do a GSX verification machine first, check whether the various information of the machine is accurate, whether there is expansion and modification, whether there is a network lock activation lock, etc.
