Users in the mobile phone after the fall conference, ushered in the Apple iPhone and Samsung Note the new phone. Samsung in order to be able to dance with Apple on the same stage, but also skip the naming rules of 6, directly from the name to upgrade to 7.
“Hiss” ring iPhone 7 series phones and “a word” to the explosion of the Note 7 mobile phone, after the fall conference after the peak season, and finally “surprised at first sight” of the market. These two currently represent the top-level handsets in both the ISO and Android camps, and despite their small footprint, are still leading the way in terms of stand-alone shipments, representing the industry’s most advanced process technology Research and development and the most powerful supply chain management level.
In addition to Apple announced that its first iPhone 7 series mobile phone within a few days has been completely sold out, Samsung in less than a month and re-organized 500,000 new battery Note 7 to the United States, more than 90% of the Note 7 users choose a new, direct refund of less than 10%, which is less than 50,000 people. This ratio for a total recall of 1 million, the US market, the Samsung Note 7 is still very successful. Note 7 Due to the battery accident, 2.5 million cell phones with quality problems need to be recalled from the market.
Apple and Samsung have adopted a lot of innovative technologies in new phones, such as Apple’s A10 computer chip, imitation glass metal case, with AI learning extension of the “dual camera” camera, with W1 chip wireless headset, active waterproof Functions such as Samsung’s iris recognition, “three defenses”, flexible surface display, double-curved cover glass, S PEN underwater operation. Two leading mobile phone brands, in the smart phone technology, have reached the current industry’s highest level. 7201k2zge
However, as a pioneer in the development of technology, Apple and Samsung have to bear the product defects brought about by the market risk. Which Samsung Note 7 battery explosion, so that Samsung had to recall the use of the same batch has hidden batteries of 2.5 million mobile phones, can be described as heavy losses.
Samsung’s Note 7 phone, due to the use of double-curved cover glass, to control the weight of the phone made more stringent requirements. Although Samsung has adopted a thinner flexible AMOLED display, significantly reducing the weight of the touch display module, but Samsung did not give up to optimize the weight of their mobile phone control. Industry analysis, Samsung in order to limited space, enhance the capacity of the battery, some models sold in Europe and America, using the latest battery separator technology to produce thinner battery separator, so that the battery performance better.
However, it is this technology upgrade, so that Samsung’s battery in the assembly process, the need for more precise process tolerance control measures. Samsung itself also said that if the battery assembly process, subject to unexpected pressure squeeze, resulting in deformation of the battery separator thickness, it is likely to change the spacing between the electrodes in the battery is full or overcharge caused when the breakdown short-circuit, causing fire Explosion.
However, in the Note 7 for the full dismantling and analysis, there are mobile phone industry practitioners, Samsung Note 7 in other designs, but also to the battery more harsh use of the environment. “Samsung is also in order to improve the performance of the CPU to the CPU to increase the heat of a piece, but the root piece directly attached to the battery and the metal in the box, is equivalent to the CPU High temperature heat directly to the battery, once the user runs the phone at high load, heat will soon be gathered to the battery. 74435572200
He said that Samsung uses double-curved glass cover design, because the thermal conductivity of glass itself is now only one hundredth of the popular aluminum alloy body, thermal efficiency is poor, leading to Samsung’s battery is always in a high temperature environment. “And Samsung’s wireless charging sensor is also in the battery above, in the charging state of the battery with the charge sensor heat generated are not easily transmitted out.”
According to his analysis, Samsung should also take into account the impact of this area, so the user does not replace the new machine before the recall of hidden mobile phone, through the remote lock to limit the battery charge capacity of about 60% to avoid Charging and intense operation, the battery capacity is too high and lead to security incidents. “Samsung, like Apple, the components of the integration done very high, the motherboard as small as possible, the distance between the components are very close, so the limited space, the work of the energy components to disperse to go out very test Their design capability. ”
I do not know is not a coincidence, the market also verified the analysis of the industry. South Korea Herald Tribune reported that South Korea started the replacement of 100,000 after the implementation of replacement mobile phone after the new battery problems still exist. Samsung’s after-sales department found that some users get a new phone charging is easy to overheat, when the phone’s charging circuit to start the protection mechanism, the new Note 7 mobile phone power will quickly run out.
Apple’s new machine market, also encountered some of the risks brought about by technological innovation. Mentioned earlier, some users to buy the iPhone 7 mobile phone will be in high-load operation, A10 near the main chip came the “hissing” noise. Apple on this issue, although not given a specific explanation, but the mobile phone peer has been found from some of the Doubt.
Apple in order to hide the user has been criticized the antenna “leucorrhea” problem, not only redesigned the phone’s metal case, but also enhanced the phone’s antenna design. “But Apple still retains the 3D pressure on the new machine touch function, during charging or high-speed operation, baseband chip noise, functional chip noise, display and battery power management device noise, it is easy to be capacitive touch snesor sensor And pressure-sensitive snesor sensors to capture and amplify.And Apple has adopted a different from the traditional analog signal pure digital signal-driven audio program, it is not clear how Apple is dealing with its audio noise correction, it is difficult to say that the cries “The noise has nothing to do with Apple’s current structure.”
Apple and Samsung released the information are said that the next generation models will be introduced into the 3D surface double cover glass program. From the current two models revealed the information displayed on the show, Apple and Samsung are looking forward to the next generation models, all the components, are completely coated in the glass inside.
In order to achieve this effect, cover glass manufacturers in addition to overcome the difficulty of the current 3D processing bottlenecks, but also need to overcome the more optical coating technology. There are sources, Apple and Samsung are required to provide cover glass manufacturers can directly on the glass cover the processing of the camera lens optical layer to replace the current camera blue glass, reduce the glass digging holes.
At the same time in order to strengthen the strength of glass or thermal conductivity, to the glass cover composite materials of other technology has also attracted the attention of Samsung and Apple. “At least on the back of the glass, it is possible to integrate the metal frame layers of the various antennas and glue them directly onto the inner surface of a moderately thick glass cover,” said the source. “It is possible to solve the two Signal with battery problem. “
