September is the time when Apple regularly releases new phones, but in 2020, the new iPhone is late for well-known reasons. Finally, at 1:00 a.m. Beijing time on October 14, the launch date of the new iPhone 12 was delayed. < / P > < p > finally, the pre-sale was opened on October 16. The first batch of users placing orders on the official website received the new iPhone 12 on the 23rd, and Xiaobian also received the iPhone 12 on the same day. As the editor of the charging head network, he naturally focused on the charging of the new iPhone, and there were a lot of things to talk about this time. < / P > < p > the packaging box of the new iPhone 12 inherits the packaging style of previous generations of iPhones. The front of the whole package box only has the front display picture of the new iPhone, and the outline of the display diagram is protruding compared with the surrounding blank area. I believe that many users who have used iPhone know it well. < / P > < p > the side of the box is very simple. An apple with a bite is the logo that makes iPhone famous all over the world and fully represents apple. < / P > < p > on the other side, the logo of iPhone. Apple does not indicate the specific model of the mobile phone on the packaging box, but only replaces it with iPhone. < / P > < p > the text message on the back is separated from the top. The information on the top introduces the products attached in the box and some new technologies carried by the new iPhone. This is also the first iPhone to support 5g. In the face of the fact that Android has not known how many phones have been updated, the iPhone 125g seems to be late. < / P > < p > at the bottom is the model of the new iPhone. Ch / a indicates that this iPhone is the version of the Bank of China. The small version of the iPhone is a white appearance and 64GB memory iPhone 12. < / P > < p > compared with the previous box, the new iPhone 12’s box is “thinner” and half as thin. Now the thickness of the two boxes can only match the thickness of the previous box. < / P > < p > tear off the transparent protective film of the packaging box, and the green arrow indicates the direction of opening, and it is a one-time seal, which can not be restored after being unsealed, which can avoid buying a secondary packaging machine. < / P > < p > open the packing box directly. It’s not so hard to open it. You can open it directly. In the impression of Xiaobian, when holding the box and lifting it up, the lower part also follows, and then slowly slides down. This time, the iPhone 12 can be opened directly. < / P > < p > after taking away the new iPhone, the accessories inside are also very different from before. Yes, as said in the press conference, all new iPhones will not be equipped with charging head and wired headset from now on, only a fast charging cable will be attached, so the packing box will be different. < / P > < p > in the past, the paper accessories have changed from rectangle to square, the logo sticker of Apple belief has become one, and the iconic card pick-up pin is still there. < / P > < p > before, most iPhones were equipped with a 5W charging head and a usb-a to lightning charging cable. This time, Apple has “slimmed down” the accessories attached, and only one usb-c to lightning fast charging cable is attached. < / P > < p > and a usb-c to lightning fast charging line also costs 145 yuan. Apple chose to cancel the 145 yuan charging head and 149 yuan wired headset, and replaced it with a 145 yuan fast charging line. The reason given by apple is that for the sake of “environmental protection”, many users have many charging heads in their homes, and users can use the old charging head to charge the new iPhone. How do you understand this view of apple? < / P > < p > turn back to the main topic and take a look at the fast charging line attached to apple. There is designed by apple in california assembled in China on the inside, which is also designed for apple to assemble in China. In addition, Apple has also marked the serial number of the attached fast charging line. < / P > < p > the editor uses the chargerlab power-z mf001 tester to test the lightning connector of the wire rod. From the screen of the tester, it can be seen that the ASIC and PMU of the data line are original c94 components, with a score of 100 points. < / P > < p > after simply looking at the accessories, let’s take a look at today’s main character iPhone 12. Unlike this packaging, the iPhone 12 does not use the front and back plastic film, but only pastes a pure white film on the screen. The position of the mute button and the volume key are also indicated at the position of the film. < / P > < p > the iPhone 12 released this time has five colors: black, white, red, green and blue, of which blue is a new color for the iPhone 12 series. The white is not pure white, but a milky white feeling, looks very warm. < / P > < p > finally, the iPhone 12 can stand up without any object, which is the biggest change in the appearance of the new iPhone, all returning to the clear water chestnut frame. < / P > < p > the camera still adopts the matrix appearance, and the rear dual camera is composed of 1200W pixel wide-angle lens, ƒ / 1.6 aperture, 1200W pixel super wide-angle lens, ƒ / 2.4 aperture and 120 ° viewing angle. < / P > < p > on the right side of the phone are the classic mute button and volume button. Although the border has been changed from radian to water chestnut, the volume button is still in the shape of a long strip. This time, the iPhone 12 also moved the SIM card slot from the right side of the phone to the left side. In addition, the upper and lower sides are antenna partition strips. < / P > < p > from left to right, the holes for loudspeaker, lightning charging interface and microphone are in turn, and the antenna strip partition is on the right. < / P > < p > after setting, you can directly enter the main screen. It is still the design of the full screen with bangs, with four sides of equal width. The screen of the iPhone 12 is different from that of the iPhone 11 series. The four iPhone 12 models are equipped with super ceramic crystal panel as standard, which is a product jointly developed by apple and Corning. The anti drop ability of the product introduced at the press conference was improved by four times. < / P > < p > the front fringe area is still one of the areas with technology since the iPhone X. the small bangs are crammed with multiple sensors including face recognition components. The front is 1200W single shot, with a / 2.2 aperture. It supports portrait mode. The Dolby horizon HDR video shooting can be up to 30fps and 4K video shooting can be up to 60fps. < / P > < p > the width of the bottom of the full screen iPhone has always been the industry-leading level, but this time the bottom border of the iPhone 12 is still very narrow. < / P > < p > the actual weight of iPhone 12 is 163.2g. Despite the slight error, the whole weight is very light among all the current flagship smartphones, and there is hardly any flagship model lighter than the iPhone. < / P > < p > although the iPhone 11 is the previous generation of iPhone 12, putting the two iPhones together can clearly feel that they are not the same year’s iPhones. Compared with the bangs of the two iPhones, the width of the iPhone 12 is narrower than that of the iPhone 11, and the position of the bangs is a little smaller than that of the iPhone 11. < / P > < p > speaking of the frame design of the new iPhone, I can’t help but think of the last generation of iPhone designed by jobs. The original design of the iPhone 4S is very novel, and the return of the iPhone 12 series border design may be a tribute to the past glory. < / P > < p > charging requires the participation of charging heads, charging lines and devices. This time, apple only provided devices and charging lines. From the standard configuration of 5W charging head and charging line for users before to only equipped with fast charging lines, it is believed that many users need to get used to it. < / P > < p > as shown in the figure above, the usb-c connector is connected to the charger end of the wire. If you want to charge the iPhone 12 normally, you need to use the usb-c output charger on the left side of the figure above. The usb-a charging head (right side) of the old model is not compatible with the fast charging cable in the box. < / P > < p > maybe the perception of wired charging is not strong, but the wireless charging of iPhone 12 has changed a lot. From the previous Qi wireless charging to MagSafe wireless charging, that is, the new magnetic suction wireless charging, Apple’s first magnetic suction wireless charger has been launched simultaneously, which can provide high-power wireless charging for the iPhone 12. < / P > < p > since airpower was abandoned by apple, Apple has changed its wireless charging strategy. From the time when the iPhone needed to find the coil actively, now it can use the magnetic suction effect to make the coil actively find the iPhone to realize the charging as apple said. The actual experience is true. Just put the iPhone in the approximate position of the charging board, and then the charging board will automatically Attached to the back of the phone for wireless charging. < / P > < p > and the strength of the magnetic force is OK. Xiaobian has tested that the iPhone 12 can be lifted through the magnetic force of the charging board, and it can not fall off. Of course, we still don’t try to use it. After all, it’s not stuck on it. In case it falls off < / P > < p > of course, if you feel troublesome, you can use your finger to push the MagSafe magnetic suction wireless charging board when you pick up the phone. As long as the position is staggered, you can take it down smoothly. < / P > < p > the iPhone 12 is no longer equipped with a charging head in the box, so consumers need to purchase the charging head by themselves. So this time, I selected several typical chargers to see the performance of the whole charging process for the iPhone 12. < / P > < p > first, use Apple’s original 5W charger to charge the iPhone 12. Before 2 hours and 15 minutes, the charging power has been maintained at about 5W, which is very stable. Then the power and current gradually decreased until the end of charging. The whole process took about 3 hours and 19 minutes, and the maximum power was 5.04v 0.97a 4.92w. < p > < p > then Xiaobian asked Apple 12W charger to charge iPhone 12. From the figure, we can see that the voltage input is stable, while the current has been in a state of decline. The whole process takes about 2 hours and 35 minutes, and the maximum power is 4.98v 2.34a 11.71w. Compared with the 5W charger, the charging time is nearly an hour shorter, but it is not enough to see. < p > < p > use Apple’s 18W charger to charge the iPhone 12. After a short shutdown and charging, the phone turns on, and then the voltage jumps from 5V to 9V fast charging. Before about 18 minutes, the voltage, current and power platform all maintained stable input state, and then the current and power decreased in a step-by-step manner. After about 13 minutes, the power and current gradually decreased until the end of charging. The whole process took about 1 hour and 42 minutes, and the maximum power was 9.09v 1.97a 17.97w. < / P > < p > Apple has added a 20W charger to the new iPad and iPad air 4 as standard. Xiaobian also bought this charger for testing. The first three data platforms were relatively stable at about 16 minutes, and then the current and power decreased step by step. After that, the voltage dropped to 5V input at 48 minutes. After 14 minutes, the power and current gradually decreased until the end of charging. The whole process took about 1 hour and 41 minutes, and the highest power was 8.90v 2.06a 18.41W。 < / P > < p > finally, Xiaobian found Xiaomi 65W gallium nitride charger, which is very popular in charger aspect, to charge iPhone 12. The overall test process is roughly the same as that of 20W charger. The whole process takes about 1 hour and 42 minutes, and the maximum power is 8.93v 2.18a 19.48w. < / P > < p > finally, for the convenience of viewing, Xiaobian drew the data of the whole charging process of the five chargers for the iPhone 12. From the curve, the charging data of Apple’s Wufu Yian is still so “stable”, charging 18% of the power in half an hour and charging in one hour
