Apple finally Of the two new phones, what new features and improvements will the iPhone 5S have as an upgraded version of iPhone 5? Should iPhone 5S users who used to only have iPhone 5 pay for it?

First of all, we can easily see from the official publicity that the upgrade of iPhone 5S to iPhone 5 is mainly in fingerprint recognition, 64 bit A7 chip, camera and wireless network.

Touch ID Fingerprint Identification

In fact, fingerprint recognition is not a new word for smart phones. As early as Windows Mobile, some business models have fingerprint recognition ▼

And the new flagship mobile phone A880 recently launched by Fantai has also added fingerprint recognition on the back of the phone, and has also realized the function of touchpad ▼

The iPhone 5S uses the Home key at the location of fingerprint identification. We just need to put our finger on the Home key to unlock the phone, which is more convenient and fast than the previous way of entering passwords and graphics. In addition, Touch ID has some outstanding features. For example, it will automatically fill in the fingerprint integrity after multiple uses. The more you use it, the higher the accuracy. At the same time, the sensor resolution of iPhone 5S is higher than that of general fingerprint recognition

A7 chip

For most users, the A6 chip on iPhone 5 is strong enough, and the combination of dual core Swift 1.3GHz and SGX543MP3 is strong enough. Of course, Apple will not fall behind in the hardware arms race. This time, the A7 chip paired with the iPhone 5S is the first 64 bit processor in smart phones. Apple also claims that its processing performance will be twice that of A6. Of course, we should know that a 64 bit system is composed of 64 bit processors, 64 bit operating systems and 64 bit software. For the iPhone 5S, iOS7 is also an operating system that supports 64 bit creation. The next problem is the popularity of 64 bit applications. In addition, the GPU of A7 is also powerful, and the promotion of "twice the graphics performance" has appeared on Apple's new products for many times. The graphics processing capacity of the iPhone 5S is twice that of the iPhone 5. The GPU with A7 also supports OpenGL ES 3.0, which is also a new technology supported on the 2013 Nexus 7. According to the above characteristics, the iPhone 5S is likely to use PowerVR 6 series chips. Although twice the graphics processing capacity of the iPhone 5 is not enough to compete with the Adreno 330, which is the strongest Android for the time being, we should think that the iPhone 5S still maintains a low resolution of 1136 * 640, so the game performance of the iPhone 5S will be unprecedented.

In addition to the performance improvement of the A7 chip, the iPhone 5S also has an M7 coprocessor that works with the A7. It is responsible for measuring motion data from acceleration sensors, gyroscopes, and compasses. In this way, the A7 does not need to be used during some low load operations, thus reducing power consumption. This also reminds us of the "4+1" structure in Tegra 3 and Tegra 4, where the "1" is also a low-power coprocessor responsible for some low load operations.

camera

Since the iPhone 4S, Apple phones have used an 8 megapixel camera. The 8 megapixel camera is still used on the iPhone 5, but the effect has made great progress. This time, the iPhone 5S still uses an 8 million pixel camera, but the sensor and aperture of the iPhone 5S have been enlarged. The sensor has increased by 15%, the aperture has increased to f/2.2, and the size of a single pixel has been increased to 1.5 microns. The iPhone 5S also has two LED fill lights, and the colors of the two fill lights are different, white and yellow. Through the use of intelligent software algorithms, it can be combined into more than 1000 different combinations to adjust the intensity and color temperature of the fill light to better take pictures at low brightness.

wireless network

In addition to the common GSM and CDMA dual versions, the iPhone 5S also has three LTE supported versions coded A1453, A1457, and A1530. The A1530 supports FDD-LTE and TD-LTE.

Although the iPhone 5S has brought about improvements in all aspects, it still has many regrets. We have not seen a larger screen, a 12 megapixel camera, or a larger battery capacity. From the perspective of hardware, its improvement over the iPhone 5 may be more difficult to attract old users to replace it. Of course, compared with the iPhone 5C in the same period, the price of the iPhone 5S is less than 1000 higher than that of the iPhone 5C, and it can get better performance and photography. The cost performance ratio is still relatively higher. For iPhone 5 users, the iPhone 5S is not attractive to them. For some new users who want to experience iOS, the iPhone 5S is undoubtedly a good choice.
