Why do all mobile phones, not just iPhones, prefer one-piece bodies?
If you pay attention to the new phones released in 2015, you will easily find that in addition to the hardware configuration, the appearance design of smartphones is also gradually becoming unified. As a joke, today's smartphones are exactly the same if you cover the trademark. Of course, this is partly because the design of smartphones has reached a bottleneck period. In the absence of breakthroughs in technology and new materials, it is destined that there will be no major breakthroughs in design in the short term. On the other hand, with Apple dominating the market, various manufacturers will naturally adopt designs similar to Apple's in order to attract users and reduce risks. So in recent years, we can see that metal frames, three-section back covers, 2.5D glass and even protruding cameras have all become popular without exception. The all-metal integrated body that Apple mainly promotes on the iPhone 6 has also begun to be widely adopted recently. It is foreseeable that in the coming 2016, most new phones will still adopt this design. However, when it comes to the integrated body design, we have to mention another topic, that is, the issue of removable batteries. When the iPhone 4 came out in the early years, the debate on whether the battery should be removable had already begun. Although until today, neither side of the debate has produced enough evidence to overwhelm the other. However, for manufacturers, the choice is very clear. Abandon the removable battery design and turn to an integrated body. So we can't help but ask, what are the advantages and disadvantages of the integrated body design? 1. Advantages First of all, from the perspective of the development of smart phones, lighter and thinner is destined to be the overall development direction of the industry. On the one hand, lighter and thinner smart phones can bring a huge improvement in hand feel. On the other hand, lighter and thinner smart phones are obviously more suitable for people to carry when traveling and reduce the burden. It can be said that the integrated body has a natural advantage in making lighter and thinner smart phones. For mobile phones with detachable back covers, in order to protect the battery and the internal circuit of the mobile phone, a layer of plastic must be used to separate the battery from the inside of the body. And this design will design both the SIM card slot and the TF card slot. Obviously, this card slot design is not only more complicated in design, but also wastes a certain amount of space. It can be said that without the removable back cover, the space inside the body can be more fully utilized. Under the same components, the volume of the integrated body is significantly smaller. From the perspective of the mainstream development direction of smart phones, three-proof and even N-proof are destined to become a major development trend in the future. The integrated body has a natural advantage in three-proof. As we all know, the key point of a three-proof mobile phone is to minimize the exposure of parts, add a cover at the USB interface, and add a waterproof rubber ring inside. However, the removable back cover is obviously not good in this regard. With the increase in the number of disassemblies, the plastic structure of the back cover of the mobile phone will gradually age and fall apart. Even the back cover with waterproof function will become unsealed after being disassembled many times. Moreover, even with advanced technology, there are still gaps during manufacturing. The integrated body does not have to worry about these problems at all. It is foreseeable that in the case of wireless charging, wireless transmission and Bluetooth headsets, the future mobile phone can completely achieve no interface on the body, so that the three-proof function can be achieved to the extreme. The integrated body design also has certain significance in terms of safety and aesthetics. For the removable battery design, some users may choose other cheap batteries because the original battery is expensive, but they don’t know that safety hazards are buried. Moreover, when the mobile phone is lost, the non-removable battery will give the user a certain amount of time to remotely locate the mobile phone or destroy the data in the mobile phone. On the other hand, the removable back cover will definitely have more slots and gaps than the integrated body, and the thickness problem will greatly reduce the appearance of the phone. 2. Disadvantages After talking about the advantages, let's take a look at the disadvantages of the integrated body. First and foremost, the problem is the battery life. In today's world where battery technology has not made a big breakthrough, the battery life of mobile phones has always been a headache for people. The problem with the integrated body is that it firmly limits the battery capacity inside the phone. Although the integrated body is good for power optimization, it is not as comfortable as changing the battery at any time. Of course, some people may say that this is not a problem at all, after all, we still have mobile power banks, right? However, the convenience of carrying mobile power banks is far inferior to the second battery. Even with fast charging, it seems vulnerable in the face of BUG-level tricks such as replaceable batteries. Moreover, although the stability of the current mobile phone system has reached a very high level, there are still cases of freezing. If it is a removable battery, the problem can be solved by simply pressing the button when the phone freezes, which is convenient and quick. Secondly, the integrated body also brings a lot of trouble in maintenance. Because it is an integrated body, users can only choose official after-sales service, although the quality is greatly guaranteed. But at the same time, its price is also "very beautiful". Moreover, for users, the IMEI code of the integrated body mobile phone will be directly printed on the outside of the mobile phone, which will affect the appearance to a certain extent. At present, the integrated body design can significantly reduce the thickness of the body, and it has strong impact resistance. Even if it falls accidentally, there will be no big problems. The overall airtightness of the body is also better, which can effectively prevent dust from entering and better protect the phone. These advantages can completely outweigh its disadvantages. It can be seen that the integrated body design must be a major trend for future mobile phones. However, what new tricks can each mobile phone manufacturer play on the integrated body, and how to solve the antenna problem, these are the real focus of our attention in the future.
