How to increase the memory of iphone5s;
Iphone5s uses built-in memory and cannot be expanded. Choose a large capacity when you can buy it.
Built-in memory is the memory solidified in electronic equipment, just like the hard disk of a computer, which determines the capacity of user equipment.
From the early 16M and 32M to the present 64M, 128M and 256M, and the existing 5 12M and 10Gb. Moreover, with the progress of technology and cost reduction, and in order to meet the needs of consumers, the mainstream built-in memory of most electronic devices has been significantly improved, such as mp3, and most of them have reached the G level.
IPhone5S is newly equipped with a touch ID. The surface of the new Home button is laser-cut sapphire crystal, and the button is surrounded by a stainless steel detection ring. The lower layer is a capacitive single touch sensor, and the lower layer is a touch switch. Sapphire crystal generally refers to synthetic sapphire, which can be made into various colors by adding various chemical elements, and the common one is colorless. Its advantages are higher hardness and higher price than ordinary glass.
Sapphire is a general term for corundum gems of other colors except ruby. Its main component is alumina (Al2O3), which is blue because it contains trace elements of titanium (Ti4+) or iron (Fe2+). It belongs to triangular crystal system, and its crystal morphology is often columnar, short columnar and plate-shaped, and its geometric shape is mostly granular or dense block. Transparent to translucent, glass luster. Sapphire has a refractive index of 1.76- 1.77, a birefringence of 0.008, and strong dichroism. Not an isotropic body. Sometimes it has a special optical effect-starlight effect. The hardness is 9, second only to diamond, and the density is 3.95-4. 1g/cm3.

Jony Ive, Apple's vice president of design, said in an interview with the Financial Times that Apple invented a new ultra-hard 18K gold material, which can effectively solve the durability problem of watches. The author of the Financial Times also speculated on its description, claiming that "Apple uses new technology to combine gold molecules more closely to achieve high hardness", but this view was later overturned by the editor of Ars Technica.
In fact, through the industrial design patent applied by Apple, we can see that Apple uses the special gold production process of Apple Watch Edition, which involves mixing gold powder and ceramic powder, and then heating and compressing them to form a harder and more scratch-resistant material than ordinary gold. However, "ceramics" is just a vague term. As can be seen from its patent, the description of raw materials is more than two lines, including boron carbide, diamond, titanium nitride, aluminum ferric silicate, silicon carbide, aluminum nitride and so on, which is very complicated.
In the manufacturing process, the key point is to build the prototype with this porous ceramic material and fill it with gold material. Simply put, a metallurgist constructs a multilayer ceramic, then injects gold into it for fusion, so that gold molecules are inserted between ceramic molecules, and then compresses and heats it until the metal and ceramic become solid substances. In the end, the stunning 18K gold Apple Watch body was formed, which is also a process equivalent to "hand-customized" luxury goods.
Interestingly, the patent also describes another method, that is, adding diamond particles (carbides) as "wetting agents" to build gold equipment. In other words, Apple is still brewing a new way of metal fusion, that is, combining gold and diamonds.
Although all this sounds avant-garde, in fact, Swiss luxury watch manufacturers have made "magic gold" by mixing ceramic materials into 20 1 1. Of course, for a technology company, Apple's research in materials and metallurgy has reached the level of a jewelry manufacturer, which seems to indicate that the company will focus more on luxury electronic consumption in the future.

Hermes Edition: This series is jointly created by Apple and luxury goods company Hermes [1]. There are three strap options, namely single patrol, double patrol and cuff.
Since its debut in June, 20 15, consumers can only buy this series of watches in certain boutiques and Apple retail stores such as Los Angeles, San Francisco, new york, Toronto, Milan, London, Tokyo and Beijing.
