What are the advantages of iPhone 6S compared to iPhone 6?

We bought both the iPhone 6 and 6S plus on September 25 when Apple released its new model. Then we go back to our testing laboratory, and in these days the team members are non-stop to them on a doubled study of testing the performances of both new phones. Compared to last year when I stayed up all night to give you the scene, this time it is quite different. Standing on such a neutral position, we aim to bring potential buyers a more objective truth.

The appearances of two models are almost the same, but there are only several differences in details. First, the biggest change is certainly iPhone 6s added a rose gold, it was said that this is in fact pink, why call it gold? "Rose gold" originally refers to the gold-copper alloy which is common in jewelry industry, is composed of yellow gold and brown copper synthesis that is very similar to the rose metal. Gold price is raised up by Chinese aunt who again and again bargain-hunting, they can’t wait for each finger to wear a gold ring. Rose gold seems introverted luxury, elegant chic. May the similar plot will immediately stage in the field of mobile phones.

Another change is behind the words of the “iPhone 6”, added a big letter "S", is this not normal? Not normal, on the back of neither iPhone 4S nor 5S there is no “S”, it seems Apple is more and more understanding on consumer psychology of Chinese people who like to show off and love the face. This letter lets everyone lost into the problem of whether wearing a case for phone or not. It is imagined that transparent shell may be on hot sale. Compared to the previous generation, their front size has not changed, but the thickness increased by 0.2 mm that insignificant two A4 paper thickness. And the iPhone 6S weight increased more 14 grams, an increase of 11 percent, which in hand feeling can be suddenly reflected, grabbed up feeling heavy. The main reason for this is the increase in 3D Touch that requires pressure sensors, chips and motors and other components.

The metal body of iPhone 6S adopts 7000 series of aluminum alloy. The shell is mixed of different metal elements, from 1000 to 9000 nine series, iPhone from 5 to 6, has been used with 6000 series of magnesium, aluminum, silicon alloy, relatively soft, relatively easy to cut on the machine , easy to processing, but the strength is not enough, easy to bend. 7000 series is aluminum, zinc, manganese alloy, is the highest in all series of a class, can be very effective to improve the iPhone "soft bone" disease. But the first problem is the 7000 alloy is difficult to deal with, this point does not matter with our consumers. With good cutting head or more than a few burns a few knives it will be solved. The second difficulty iPhone 6s is not easy to color when anodized. Apple thickened the metal surface of the antioxidant layer of iPhone 6s. Just be careful, try to avoid the keys and other sharp items to together with your phone.

The A9 CPU equipped in iPhone 6s is Apple's third-generation 64-bit processor. Samsung and Apple have been bite very tight for position of the strongest mobile phone CPU. The performance of Exynos 7420 has beaten Apple A8, and this time A9 ushered in a substantial upgrade, we simply use Geekbench run to do An intuitive comparison, A8 single-core performance is 1627, A9 single-core performance reached 2500 +. IPhone 6s is able to have more than 50% performance improvement, we should cherish it. The reason is that the highest operating frequency from 1.4G straight up to 1.83G, the other Secondary cache increased from 1M to 3M, especially the later gets a huge impact on the CPU.

IPhone 6s is installed with 2G processing memory. Apple IOS system has always been very good for hardware optimization. Even small cache also has a very good experience. But the reason behind it is: only in the absence of considering of different hardware compatibility you can do a good job, iOS memory management precision to every 1Kb. So in every time of Apple's important system upgrade, you have to give up the old model since cache can’t support fast processing of new version. If you buy an iPhone 6S, may be when iOS12 or 13 release, your phone can’t be upgraded, all you can do is buying another new one. At this stage of the iOS system and the software on the platform are not for 2G memory to do optimization, a variety of application experience are the same, only in some extreme use, such as when at the same time open dozens of large pages, or at the same time open more than 30 applications, you will see the difference. The advantage of 2G memory will be reflected only in the future.

If use one word to describe the advantage of iPhone 6S compared to iPhone 6, that is "fast". Fast hardware performance, fast fingerprint recognition, Siri fast response, and 3D Touch brought the efficiency of the acceleration, especially the big move 3D Touch again opened with the advantage to Android phones. If you buy a refurbished iPhone 6s, at least you won’t suffer. After all iPhone 6S is still one of the most brilliant smartphones from the point of comprehensive capability.
