iPhone 6S internal hardware circuit design exposure: or support fast charging

Recently, more and more news about the next generation iPhone 6S, from camera pixels to 12 million pixels, using dual cameras, front camera with flash, support night self-timer, then fingerprint recognition technology, then cancel the home button, by The touch button is directly replaced, and every time the news bursts, it represents the next generation iPhone 6S wants to take a different approach from the current smartphone design, and thus stand out. It is said that the iPhone 6S mainly has two major versions. With the screen size almost unchanged, it will use a more powerful processor and upgrade to 2GB of running memory, which is more smooth. In addition, it is said that a new generation of iPhones has a pink color, which is expected by many female users. A lot of information is currently indicating that this new iPhone will be an upgrade and improvement of the iPhone 6/6 Plus.

According to the latest leaked logic board photo of the iPhone 6s prototype, the new module is equipped with Qualcomm's MDM9635M chip, which belongs to Qualcomm's fourth-generation LTE baseband Gobi 9X35 mobile platform. The speed is twice that of the Gobi 9X25 platform currently used on the iPhone 6, reaching 300Mbps, but the uplink rate is still 50Mbps. However, Apple is not the first company to adopt the MDM9635M chip, and Qualcomm has already launched the chip as early as the end of 2013, but due to the delay in standardized production time, it was not loaded to the Samsung GALAX S5 for the first time until last year. The key to the increase in the speed of the chip is to support LTE Cat.6 technology, which is twice as fast as the LTE Cat.4 technology provided by the iPhone 6 on the 4G network.

Processor chip 14nm and 16nm process Apple A9 platform, power optimization is a bright spot equipped with the new Apple A9 processor is already well known, but Apple has never published too much information on the processor, according to the current supply chain Information, the biggest feature of the A9 processor should be the improvement of power consumption, there is no revolutionary upgrade in performance, so the processor surprise may be limited. According to reliable sources in the relevant supply chain, the Apple A9 processor is actually a fine-tuning of the "Cyclone" architecture. The architecture starts with the A7 processor and the A8 processor is Enhanced Cyclone. A9 is likely to be upgraded on the basis of A8, so there should be no fundamental performance changes.

From the overall design concept of the previous A8 processor, whether it is process technology, graphics chip, or M8 coprocessor, Apple's focus is more on power consumption and battery life. Plus the iPhone 6's battery currently does not exceed 2000 mAh, so it is expected that the A9 processor will agree to continue the previous chip ideas. Of course, this does not mean that performance has not improved, but in many aspects of hardware upgrades, more improvement will be in the reduction of energy consumption, rather than the arrogance of performance.

Even though the performance and architecture of the A9 processor will not be revolutionized, the 14/16nm FinFET manufacturing process is one of the highlights, and it has a more eye-catching performance in the graphics GPU. Samsung's 14nm Exynos 7420 Just about 40% of the graphics performance of Apple A8, I think everyone will see the power of this chip. However, it is important to point out that there are news that Apple's 14nm process chip can't meet Apple's huge market demand, so Apple will hand over some orders to TSMC. But the problem is that TSMC uses the 16nm process. Whether the chips under these two processes have performance differences is still unknown, but if it is true, then it will be necessary to entangle the user again in the future.

The fuselage capacity is still 16GB, but the running memory is upgraded to 2GB for the first time.

Previously, there was a lot of information to pass Apple to increase the standard capacity to 32GB, and 16GB will go into history. However, according to the current spy photos and chip information, the new iPhone's body capacity is still 16GB, and it provides 64GB/128GB high-capacity version, and has not made any other changes. The significance of the existence of the 16GB iPhone is not difficult to understand, especially in China. Many users' needs for the iPhone are still in simple daily use and a small number of applications. Without a lot of music and video, they don't need a large-capacity iPhone at all, which just solves their needs. For users with capacity requirements, 16GB is obviously not enough. In this case, you can only purchase a larger 64GB or 128GB version, which is Apple's layout on a large capacity.

The latest exposure of the iPhone 6S spy photos, showing that its memory chip is still 16GB capacity, although the body memory is still 16GB, but another good news is that the running memory is finally upgraded to 2GB, and this is definitely the new iPhone in terms of hardware upgrades Obvious. At present, Android mobile phones have entered the 4GB storage era, and the iPhone 6S uses 2GB of memory, which seems to be few, but it can bring obvious memory optimization under the operating mechanism of iOS system, making running speed and multi-tasking more smooth. Previously, the feedback from the browser that the browser has opened the window will be solved. I believe this will make the iPhone 6S not lose to any Android phone.

It is worth noting that the benefits of using this Qualcomm chip for the iPhone 6s are not only in terms of download speed, but also improve battery life under 4G networks. According to the 9to5mac, the iPhone 6s motherboard is narrower and more compact than the iPhone 6, which leaves more room for the battery. Coupled with the power-saving features and low-power modes brought by the iOS 9 system, the iPhone 6s may not only be equipped with a larger capacity battery, but also the endurance performance of the whole machine is expected to improve. Just from the current exposure of the iPhone 6s shell spy photos, the machine does not have any significant changes in appearance compared to the iPhone 6, including the bottom of the fuselage and the interface completely copied the past, while the camera and microphone on the back There is also no change in the opening of the LED flash. However, the 9to5Mac does not indicate whether the exposed iPhone 6s metal case has changed in material, but it is said that the final version of the iPhone 6s will be adjusted in color, such as the dark gray version will be darker, with Apple The gray version of Watch is relatively close.

Baseband chip upgrade for Cat6-class 4G standard

The network surprise is that the baseband chips used in the iPhone 6S will be upgraded, and there will be more eye-catching performance in terms of network and speed. It is reported that the new generation of iPhone will use Qualcomm MDM9x35 series baseband chip, support LTE Cat.6 standard, the theoretical downlink rate can be increased to 300Mbps, but the uplink rate is still 50Mbps (of course, compared to the Qualcomm Snapdragon 810 Cat9 is still a lot behind) This is a big improvement over the current Qualcomm MDM9625M (LTE Cat.4, downlink rate 150Mbps) used by the iPhone 6.

Also, is the Qualcomm MDM9x35 baseband chip the latest? The answer is also to make you regret. This baseband is actually launched by Qualcomm at the end of 2013. It has been applied to the Samsung Galaxy S5/S6. It is currently the most mature and mainstream baseband chip. As for Qualcomm's latest baseband. It is an MDM9x45 series that supports the LTE Cat.10 standard of 450Mbps downstream (it is estimated that you can see it on the iPhone 7 in 2016).

The Qualcomm MDM9635M series baseband equipped with the new iPhone supports full Netcom and Cat6 4G standards, but we need to separately explain that both the existing iPhone 6 and the new iPhone 6S are multi-mode multi-frequency products. And also have already supported carrier aggregation and VoLTE, so for users, both have full Netcom features (depending on the different versions, the Bank of China should be no problem), and both support the current 4G+ (that is, LTE- A) Characteristics. As for the LTE Cat6 problem, due to the development status of domestic operators, the deployment of LTE Cat.6 has been promoted, but it will not be fully popularized to the Cat6 standard, let alone Cat8/Cat10. The actual situation is Cat4. The status quo of the network has to be several years.

Battery capacity has been slightly upgraded and will support fast charging

The most difficult thing to guess about every generation of iPhone products is the battery data. Apple's secrecy is better than other aspects. Even we need to disassemble it through the real machine after the press conference, and we can know the battery data by unit conversion. The current iPhone 6 uses a 1810 mAh battery, and the iPhone 6 Plus uses a 2915 mAh battery. According to industry sources, the iPhone 6S's battery capacity will be 1850 mAh, while the iPhone 6S Plus battery will exceed 3,000 mA. Ann (unofficial data, from the network, for reference only).

Of course, in addition to the large-capacity battery, the new iPhone will also support the fast charging function, and the A9 chip and the updated iOS 9 system will also extend the battery performance of the iPhone through various methods, which is believed to bring about certain growth.

The internal test code for the iPhone 6s series is N66 and N71, which will load 2GB of memory and upgrade the main camera to 12 megapixels, and will be equipped with a "Force Touch" panel, which is also consistent with the past. The appearance of the iPhone 6s has not changed much, and the internal promotion has been more. In addition, the iPhone 6s and iPhone 6s Plus have not changed much in appearance compared to the past. There are also two 4.7-inch and 5.5-inch touch screen versions, so in the case of similar appearance, the final assembly process is expected to be smooth. The mass production is expected to be officially released in September this year.
