More and more Americans hold the iPhone for more than 3 years

According to foreign media reports, a new survey shows that more than ever, Americans have used iPhones for 3 years or more. CIRP data shows that this proportion has risen steadily from 12% in the first quarter of 2016 to 28% this year. For Apple, the good news is that most iPhone users will still upgrade their devices every one or two years, but since 2016, the proportion of users who have been upgrading less frequently has increased year by year.

Mike Levin, a partner and co-founder of CIRP, said: "We clearly see that iPhone users have been using mobile phones longer and longer. In the most recent quarter, 28% of consumers kept their old phones for three years or more, Which was only 12% four years ago. "
"The percentage of iPhone users who upgrade their phones has remained stable at a single-digit high every year. So, the good news for Apple is that consumers are increasingly buying the latest and more expensive phones. But they now save The time is much longer than the typical two-year cycle a few years ago. This slows down the upgrade cycle and reduces unit demand in a saturated market. "
CIRP said that the basic version of the iPhone 11 is currently the most popular model.
Josh Lowitz, CIRP partner and co-founder, pointed out: “iPhone 11 is the dominant model among all (iPhone) models. Not surprisingly, it replaced last year ’s iPhone XR as the most popular mobile phone. Compared to one Similar to the high-end iPhone XS and XS Max years ago, the market share of the more expensive iPhone 11 Pro and 11 Pro Max has increased. It is worth noting that the sales share of the oldest and lowest-priced iPhone 8 and 8 Plus is relatively high Small, only 13%, lower than the level of the same period last year. The release of the new price leader iPhone SE and the possible retirement of 8 and 8 Plus should change the sales mix and further highlight the newly released models in the next quarter. "
For all high-end smartphone brands, the longer the upgrade cycle is a problem, more and more consumers believe that the difference between new models launched every other year is relatively limited, so they do not think that high prices are reasonable and acceptable Accepted.

How to choose iPhone XS, iPhone XS Max and iPhone XR? what's the difference?

At the Apple conference in 2018, Apple released a total of three iPhones, namely iPhoneXs, iPhoneXs Max and iPhone XR.
The three mobile phones in 2018 all look similar. The iPhone XS, iPhone XS Max, and iPhone XR are all designed for full-screen bangs, and there is no fingerprint to unlock. In order to make it easier for everyone to choose to buy, I will now introduce to you the differences between iPhone XS, iPhone XS Max and iPhone XR!

Screen size and display

The iPhone XR is a 6.1-inch LCD display with a pixel density of 326ppi.
The iPhone XS is a 5.8-inch OLED display with a resolution of 2436 × 1125 and a pixel density of 458ppi.
The iPhone XS Max is a 6.5-inch OLED display with a resolution of 2688 × 1242 and a pixel density of 458ppi.
The iPhone XS has the smallest screen of the three, while the iPhone XS Max has the largest screen, with 6.5 inches of space for viewing. The iPhone XR uses Apple ’s past LCD screen and lacks the pressure-sensitive 3D Touch feature introduced on the iPhone 6S. Conversely, when you long-press an icon on the display, it uses haptic feedback like a trackpad.

Material and color

iPhone XR: aluminum body with glass on the front and back; available colors: blue, coral, yellow, white, black, red
iPhone XS: stainless steel body, glass back and front; selectable colors are gold, silver, space gray
iPhone XS Max: stainless steel body, glass back and front; selectable colors are gold, silver, space gray
Camera function
iPhone XR: 12-megapixel camera (f1.8), 5x digital zoom, three portrait lighting effects
iPhone XS: dual 1.2-megapixel camera (f 1.8 wide-angle and f2.4 telephoto), 10x digital zoom, five portrait lighting effects
iPhone XS Max: dual 12-megapixel camera (f 1.8 wide-angle and f2.4 telephoto), 10x digital zoom, 5 portrait lighting effects
All three iPhones are equipped with at least a 12-megapixel rear camera (with OIS) and a 7-megapixel front camera that supports Face ID unlocking and Animojis. Although the iPhone XR lacks a second rear camera, it uses the software to shoot an artistic portrait style with a background blur effect. Smart HDR is a new feature that is suitable for the automatic detection and repair of three iPhones, bringing out highlights and deepening shadows. Enhanced portrait selfie software.

Battery Life

Apple never shares a specific battery capacity, but it does provide guidance on how long other devices can last than expected. The iPhone XR may have the three longest battery life.
iPhone XR: Apple claims it will run 90 minutes longer than iPhone 8 Plus, which is the most durable iPhone of 2017
iPhone XS: Apple claims it will run 30 minutes longer than iPhone X
iPhone XS Max: Apple claims it will run 90 minutes longer than iPhone X

Purchase advice

iPhone XR

The iPhone XR is increased to 6 colors at once, with more options, but it is not difficult to imagine the iPhone XR as the iPhone 5C many years ago. That is what everyone said is the cheap version, but the iPhone XR is positioned after the iPhone 8 and iPhone 9, which is quite satisfactory. If you are not too demanding on mobile phones, you can choose iPhone XR.

iPhone XS / iPhone XS Max

The iPhone XS is positioned in the standard version of the iPhone XS Max. The choice between the two models is nothing more than a big screen and a small screen. The iPhone XS is the most top-notch in Apple's product line regardless of the screen camera size. If the situation is ample and you have high requirements on the details of the mobile phone, you can choose any of the iPhone XS / iPhone XS Max.

Now ready to change the machine, is the iPhone 12 worth the wait?

According to Apple's practice in previous years, the new iPhone will be released in less than five months, but this year's new Apple product may have to be postponed to October. For the new product, the 5G version of the iPhone is the focus of everyone's attention. At present, iPhone 11 has started to cut prices, but it does not support 5G, so is the new iPhone 12 still worth waiting for?

Failure to catch up with the first 5G bus has affected Apple's voice volume in 2019 to a certain extent. However, this year the iPhone 12 all support 5G, and the lineup and number of models are unprecedented. In terms of storage, Apple has always been conservative, especially relative to domestic Android phone manufacturers, but this year's iPhone 12 series is expected to carry up to 6GB of storage, while the iPhone 11 series comes standard with 4GB of storage.
Increasing storage is not unfounded. If a 5G network is supported, the quality of the video or pictures loaded by the device will increase correspondingly in an ultra-high-speed network environment, which inevitably increases the operating burden. In order to ensure a good mobile application experience for users, Apple needs to ensure that the iPhone 12 series still has a smooth multi-tasking capability in the 5G environment. Only then has this action to change the traditional 4GB storage.
In addition, the area of ​​the iPhone 12 bangs will be significantly reduced compared to the past, and the design style of the appearance will be very similar to that of the iPhone 4. There is no arc treatment between the middle frame and the front and rear glass, and the design style is tougher. The Yuba lens module is still placed in the upper left corner of the back of the phone, adding the same LiDAR radar as the new iPad Pro.
As for the selling price, it has been reported that the price of the iPhone 12 may be from 699 to 799 US dollars (about 4875 yuan to 5567 yuan), and the iPhone 12 Pro series may be priced from 999 to 1099 US dollars (about 6561 yuan to 7658 yuan) Yuan), and iPhone SE2 may only need 399 US dollars (about 2780 yuan).
Although Apple ’s 5G mobile phone cost will increase by at least 20% compared with previous years, it will not significantly increase the overall selling price. The first reason is that the price of iPhone ’s high-end models is not cheap, and the current environment is not suitable for continued price increases; The second is that Apple hopes that 5G mobile phones will quickly ship to occupy market share. Excessively high selling prices are not conducive to accomplishing this goal.
If your phone has a long service life, it is recommended to wait for the new iPhone 12 to be released before starting. If the replacement cycle is within two years, it is also a good choice to start with iPhone 11.

Why will Apple use mini LED screens in many products in the future?

Although OLED has now become a very popular display technology, the display industry has turned its attention to innovation to the next major change, which is MicroLED technology. MicroLED has the characteristics of high resolution, low power consumption, high brightness, high contrast, high color saturation, fast response, thin thickness and long life. The power consumption can be as low as 10% of LCD and 50% of OLED. The next-generation display technology the industry expects.
Some well-known international companies, including Samsung, Apple and Facebook ’s Oculus, have already begun to equip future products with this technology, and various companies and manufacturers have recently begun to apply for various patents on MicrOLED technology. Starting in 2018, as major manufacturers such as Samsung, Sony, and AUO have successively launched Micro LED related conceptual products, the next-generation display technology and application market expected by the industry is accelerating.

However, such a near-perfect display technology seems to have disappeared in recent times. Moreover, in the conferences of major manufacturers including TV, mobile phones, monitors and other display equipment manufacturers, there is no trace. At most, I only saw the display machine at the exhibition.
So, what is the status of this MicroLED technology, which claims to replace OLED? What about the future? To expand on this topic, it is necessary to first introduce to you what MicroLED technology is.
MicroLED is a micro light-emitting diode, which refers to a high-density integrated LED array. The distance of LED pixels in the array is on the order of 10 microns, and each LED pixel can emit light by itself.
It is the miniaturization of the traditional inorganic LED array, each LED pixel with a size of 10 microns can be independently addressed and lit. Simply put, it can be seen that the size of small-pitch LEDs has been further reduced to the order of 10 microns. The display method of the Micro LED is very direct. Connect the 10 microns LED chip to the TFT drive substrate, so as to achieve precise control of the brightness of each chip, and then achieve image display.
The power consumption of MicroLED is about 10% of LCD and 50% of OLED. Compared with OLED, to achieve the same display brightness, only about 10% of the coating area of ​​the latter is needed. At the same time, the brightness can reach 30 times that of OLED, and the resolution can reach 1500PPI (pixel density), which is equivalent to 5 times that AppleWatch adopts OLED panel to reach 300PPI. Therefore, only from the comparison of various data, there is an opportunity to replace the current mainstream display technology.
However, to a certain extent, the most obvious manifestation of a technology's immaturity in the market is the high cost of its products. This is the case with MicroLED.
At present, MicroLED is limited by some bottleneck technologies, especially in the mass transfer process. Even if the industry can make breakthroughs, it will take time to really improve the yield and reduce costs. In addition, Micro LED also has a big problem is the full color, the consistency of the emission wavelength.
In addition, the improvement of MicroLED's entire process chain is not a result of Asahi, even three to four times that of current LCD or OLED panels. There is no doubt that this will increase the cost of the product a lot, and even affect the investment of the entire industry. After all, many manufacturers are constantly expanding the production line of OLED screens. Therefore, the manufacturing price and cost of MicroLED are also much higher. It should take time to mass-produce and replace existing products.
Therefore, this is why you will see various figures of MicroLED in large electronic exhibitions such as CES and IFA, but you have never seen any manufacturer really sell this type of display products on the market. However, in the long run, high-end display panel manufacturers will take MicroLED as the main research direction in the future, and MicroLED is likely to become the ultimate goal of the entire display industry. https://www.i-simu.com/

How to determine if an Apple phone is a refurbished one? How to identify genuinely and refurbished Apple phones!

Apple-certified refurbished products are second-hand Apple products but are subject to Apple's stringent refurbishment process prior to sale. Although only some products were returned due to technical issues, Apple has a rigorous quality refurbishment process for all products. They work 100% normally and are sold as refurbished products. Since these refurbished products have been opened and used, there may be some surface defects such as scratches, marks, or discoloration. So how do we identify whether the Apple phone is a refurbished machine when we usually buy it? Today, the mobile phone repair network will teach you how to identify genuinely and refurbished Apple phones.

The latest identification method of Apple mobile phone genuine and refurbished

Features of the official iPhones

Unlike the replacement machine, which has only a single head, the official turning machine is packed with new accessories at the factory. The picture below shows the packaging of the official iPhone 5 in a white box with "Apple Certified Pre-Owned" printed on the box.
Tag characteristics, iPhone 5 tags are not the same as iPhone 5s, they are pure black. The "RFB" in front of the iPhone 5 is the abbreviation of refurbished, which means refurbished. The official serial number starts with DQG, DQH, C7G, C3M, etc.

The model is more special, starting with F. For example, the Hong Kong version of the official iPhone 5, 16GB black: FD298ZP / A; 16GB white: FD298ZP / A; 32GB black: FD299ZP / A; 32GB white: FD300ZP / A, pay special attention to, there are In the case, the model on the box starts with F, and the model in the machine starts with N. Because the model of the replacement machine starts with N, it will be mistaken by some buyers as a replacement machine, and the combination of DQG and N also conforms to Judgment method of a replacement machine.
It can only be determined by the warranty duration. The replacement of the replacement machine from port to port has been extended from the previous one, usually from the production time to the end of the warranty, and the warranty calculation method of the official machine Like retail machines, there is a 365-day warranty after activation, so the full warranty is the official machine. For the case and box, models are different, the answer given by Apple 400 customer service is because of different batches.
It is worth mentioning that all Apple-certified refurbished products are backed by a one-year limited warranty.

Refurbished Market Status

When it comes to the refurbished market, the terms second-hand and parallel imports have to be mentioned. Refurbishment is generally second-hand or parallel imports, while second-hand and parallel imports are not necessarily refurbishment.
There has been a rumor on the Internet that the number of "born" iPhones in China is more than Apple's official shipments to China. This is the Chinese iPhone refurbishment market. According to surveys, the percentage of refurbished iPhones sold by merchants is as high as 90%. Consumers who understand the "process" of refurbishment have expressed shockingness.

These iPhones look no different from ordinary iPhones, but most of the motherboards have been replaced. You can buy iPhones in almost every country, British, Singapore, and the US. Needless to say, Simi The more up-and-coming version of Da has also become popular. It is not difficult for parallel imports to help you change to the National Bank. These refurbished machines can mainly focus on iPhone 5, iPhone 5s, but do n’t think that the latest iPhone 6 will be spared. In addition, I believe that everyone has also seen the iPhone 5c changed to the iPhone 5s such as "boutique".
There is also a place that everyone is familiar with-Huaqiangbei. According to some people familiar with the local market, here you can see the entire iPhone refurbishment process. After many mobile phones are turned on, the motherboard and most components can be used. You only need to transfer the components of other old machines to high Imitation of the rear cover, you can complete the replacement of the original screen, the most important of which is the motherboard, because only Apple's motherboard can be installed with iOS system, more skilled technicians can refurbish one in 30 minutes. Even if the second-hand iPhone is in good condition, the internal components may be brand new and inactive, but the seller is also likely to profit from accessories such as headphones and chargers.

How to identify Apple refurbished iPhones?
