Why do today's smartphones no longer support memory cards?

Once upon a time, most mobile phones on the market supported memory cards, through which your favorite music and videos could be copied to multiple devices. With a card reader, it could even be used as a USB flash drive, which was very convenient. But now, most brands of mobile phones have canceled the expandable storage function and replaced it with more large-capacity versions of 256GB, 512GB or even 1TB, with a price difference of several hundred yuan.

##Why mobile phone manufacturers want to "eliminate" the memory card slot on mobile phones ? It may be related to the following three reasons:

1: The reading speed of the memory card cannot keep up with the demand

Initially, many mobile phones will install applications in On a memory card, its reading speed will greatly affect the daily use experience, but the products on the market are mixed, and some inferior memory cards cannot meet the needs, and may even cause the phone to freeze, black screen and other malfunctions. Therefore, mobile phone manufacturers directly build high-quality memory once and for all to reduce the possibility of failure.

2: Enhance waterproofing and reduce the thickness of mobile phones

Many mobile phones now no longer have 3.5mm headphone jacks. Many friends know that this is to ensure waterproofing , reduce the thickness of the phone, and cancel the memory card slot for similar reasons. In order to make mobile phones extremely thin and light, a large number of internal components have been stacked, and a memory card module will take up a lot of space. By the way, do you want thinness and lightness, or do you want a headphone hole?

3: Manufacturers reduce distribution

On June 29, 2007, the first generation of iPhone was officially released. This phone has many historical significances. It not only adopts The leading 3.5-inch multi-touch screen and 2-megapixel camera also show unlimited possibilities to technology enthusiasts around the world. In fact, from the first generation of the iPhone to the current iPhone 14 series, the iPhone has never supported memory cards, and has also "castrated" hardware configurations such as chargers, battery capacity, and charging speeds. However, it can still remain the most popular mobile phone in the world year after year. , a nice word is called "restraint", a bad word is called "reduce allocation". Subsequently, many manufacturers have followed this trend of "reducing configurations". As long as users can accept it, the cost can be reduced.

Different users have different opinions on whether a memory card is strictly necessary.

Some foreign media once launched a questionnaire survey on "whether a memory card is strictly necessary". In the end, only 15.66% of users said that "SD expansion function is not needed", and 38.97% Users even chose "don't buy it if there is no SD expansion", while the remaining 40% of users said "it's better to have it, but it's fine without it". Even though they say they won’t buy it, generations of iPhones are still selling like crazy. This is also a kind of helplessness.
