The IPhone 5S has not impressed the media since its formal release, when feedback was limited. After an in-depth experience with the IPhone 5s, a more detailed evaluation report is released today. The article summarized 5 media's evaluation, focused on touch ID fingerprint sensor, larger aperture of the main lens and 64-bit A7 chip. Listen to their feedback ...
Touch ID
Engadget
There's a whole bunch of reasons you don't want to see fingerprints on your phone: Past models show how unreliable fingerprint identification is, and it brings more trouble than it creates. For example, the Motorola Atrix 4G with optical fingerprint scanners needs to be scanned repeatedly, but the success rate is very low.
Apple implanted the capacitive fingerprint sensor into the IPhone 5s home button, and the sensor covered with a layer of sapphire glass to protect it. The metal ring around the home key collects fingerprint information from the user and passes it to the sensor. The sensor captures the user's fingerprint image from various angles and transfers it to the A7 processor. The touch ID captures the fingerprint information from the finger's epidermis, not the skin's dead skin, capturing the image with a maximum quality of 500ppi.
The setup process is simple, generally speaking, no more than 1 minutes. The IPhone 5s stores up to 5 different fingerprints, from different fingers of the same person or from different people. Fingerprint collection looks cumbersome, but after several tests it becomes simpler. The first thing you need to do is touch the home key a few times and once you've collected enough information, the IPhone will prompt you to flip your finger to rescan. After the fingerprint was collected, the handset asked to name the fingerprint so that it would not be confused when it had multiple fingerprints. To prevent fingerprints from being unrecognizable, the IPhone 5s also requires a password to unlock the phone after the scan fails.
The touch ID is very fast and the finger touches the home key to complete the scan in less than 1 seconds. The process was so natural that we almost forgot that the IPhone 5s was set with a password and a lock screen. Countless times we subconsciously unlocked the iphone 5 and iphone 5c in the same way, only to find that the "old-fashioned" slide unlocked. Of course, the touch ID is not perfect: the fingers are moist or partially touched the home key cannot unlock the phone, but we do not find that sticky fingers can not unlock the IPhone 5s phenomenon.
For privacy reasons, Apple says all fingerprint information has been converted to digital signatures, encrypted and stored in the chip. In other words, the fingerprint data will not be uploaded to the Apple server and ICloud. At the same time, cutting off the main finger to unlock the IPhone 5s is not going to work.--touch IDs can only scan live organizations. In addition, the mobile phone reboot or 48 hours unlocked, users can only use the password to unlock.
Times
Fingerprint sensor is one of the most important features of the IPhone 5s, which is intelligently implanted under the home key. Click the Home button to wake the IPhone, and the finger touches the home button for half a second to unlock the phone. The touch ID is always valid during the testing process, unlike the previous annoying fingerprint sensor. It's really amazing that people who hate it can get a dock to jump down.
When buying books, music, and apps, you can also scan your fingerprints with a touch ID. Although there are still some bugs, Apple says it will push fix patches in Friday.

At first glance, it's easy to think that fingerprint scans are a gimmick, almost useless. But that is not the case. Touch ID is a mature feature that can increase the overall iPhone experience.
The process of registering fingerprints is also simple, and the IPhone 5s will guide the process. Users can register up to 5 fingerprints and decide which fingerprint is used to unlock the phone and which fingerprint to use for the purchase.
Once the registration is successful, you can quickly unlock the iPhone with your finger on the home key, almost as fast as without a password. Some rescan prompts are also encountered during use, but as the usage increases, the hints are gradually reduced until they are completely gone. Apple says the touch ID will increase the success rate by constantly learning the user's scanning style as the number of times is used.
AllThingsD
Laptops and mobile phones have been used in the past for fingerprint scanners, but they are unreliable and users are generally unwilling to use them. The technology used by Apple is different from the past, and the home key becomes a fast and accurate fingerprint scanner.
Apple said the death of the organization can not unlock the phone, a severed finger or a common print copy of the film does not have any effect on the touch ID.
If the scan fails three times, the IPhone 5s will display the password unlock option. After five failures, the IPhone asked for a password to unlock. Apple says the chances of an outsider unlocking a phone by a touch ID are 1/50000, while a four-bit password unlocks 1/10000.
iSight Main Lens
Engadget
Apple's attitude to the IPhone's imaging capabilities: keep getting better and simpler.
The iphone 5s daytime imaging effect is roughly the same as the iphone 5, but with a little more detail, but the low light effect is significantly better than the iphone 5: Images are sharper, richer in detail, more natural in color, and less noisy. However, compared with the Nokia Lumia 1020, the IPhone 5s proofs have much more noise and less detail. I have to admit that the IPhone 5s has a good color reduction capability, but it's still not the best player in the field.
Thanks to A7 's new Isp,iphone 5s support for automatic graphics stabilization, one exposure can take four photos. The mobile phone automatically analyzes the key nodes of each photo, such as exposure value, sharpness and the accuracy of face recognition, from which the best pictures are selected. The IPhone 5s also supports continuous shooting, taking up to 10 photos per second. The photo is automatically saved in the subfolder of the album, and you can open all the pictures when you edit it. Panorama mode is also faster than the IPhone 5, and Apple says the imaging speed is up 50%.
True Tone Dual Flash is another feature of the IPhone 5s. The IPhone 5s can determine the exposure density and the flash combination based on the ambient color temperature. The final imaging effect is natural, still life and portrait are excellent.
SLR and some high-end smartphones have supported slow shooting in the past, but most can only reach 60fps of shooting speed. The IPhone 5s captures 120fps slow video, and the user decides which part of the video can be displayed at a slow speed.

The new camera brings more content: The photosensitive element increases by 15%, and the single pixel particles increase a lot. Compared to previous generations, the IPhone 5s has a better light effect: clearer, brighter, and more accurate.
The IPhone 5s supports burst, 3 times-fold video scaling, Instagram filters and slow video. But strangely, filter pictures and slow video can't be viewed on the computer.

Apple's confidence in the IPhone's 5s camera is consistent with its Long-held view that higher pixels do not equal better photos. The 8 million megapixel iSight camera is the same as the predecessor, but is larger in single pixel size and has a maximum aperture size of f/2.2.
The camera's elevation also includes a True Tone double flash that adapts to the background light and better reflects the surroundings. When used, turning off the flash is still the best shot, but compared to the iphone 5c, it shows that the iphone 5s compensates for natural light better than the iphone 5c. (iphone 5s, iphone 5c flash proofs contrast, pay attention to protect the edge of the lid.) Pictures from TechCrunch)
Lens improvement also includes automatic graphics stabilization system, one exposure to take four photos, the system from the selection of the best one. The burst mode supports 10 photos per second, and burst photos can be used to make GIF images, and wonder why Apple doesn't have a GIF production tool?
AllThingsD
The new camera has larger photographic elements and pixel particles that can capture more light and color. All of the shots were slightly sharper than the IPhone 5, and the details of the pictures in the low light were less likely to be erased by Flash.
A7 Chip
Engadget
A7 uses the ARMV8 instruction set, which makes the IPhone 5s the first smartphone to use a 64-bit chip. In most cases, the 64-bit chip allows for better performance in supported games and high volume applications, without impacting too much battery life. The 64-bit processor-based IOS 7 system also enables developers to achieve higher development efficiencies. Apple says the A7 is twice times as fast and graphic as A6.
Although there is currently no chance to test the support of 64-bit chip applications and games, but overall, it is obvious that the IPhone 5s faster, application loading and operation smoother smooth. A7 's GPU is starting to support OpenGL ES 3.0, and the new protocol allows developers to add more complex scene details to make the game scene more realistic.
The M7 coprocessor, which is used to mitigate the A7 load, mainly handles data from gyroscopes, accelerators, and compasses. With the help of the M7 coprocessor, health classes will consume less power when they run in the background. (iphone 5, iphone 5c, iphone 5s run in contrast, pictures from Engadget)
AllThingsD
The IPhone 5s employs a 64-bit processor, which means the system can handle even more massive amounts of data. However, there was no noticeable acceleration in the test, and it may not have been possible for developers to take advantage of the 64-bit performance for the A7 rewrite process.
CNET
We live in the good times of a mobile chip, which is a fast upgrade to laptops and desktops like a few years ago. The iphone 5 runs twice times faster than the iphone 4S, and the iphone 5s runs at least twice times the iphone 5.
