In October 2020, Apple launched the iPhone 12 series, which uses a new vertical frame design and a more powerful processor to greatly improve the performance of the imaging system. In terms of charging, the wired system is upgraded to 20W PD fast charging, and the wireless system is equipped with a new 15W MagSafe magnetic suction wireless fast charging system.


Recently, chargehead.com has launched a large number of iPhone 12 series test articles. In order to avoid reading difficulties caused by the huge amount of credit, class representatives summarized the concentrated version of the homework, so that everyone can understand how the iPhone 12 fast charging is.


At the launch of iPhone 12, Apple announced that it would contribute to the environmental protection of the earth. All iPhones will no longer deliver chargers, halve the volume of the outer packing box, halve the transportation and storage costs, save the cost of chargers, and earn a good reputation. It is estimated that only apple can do this. All iPhone cables, regardless of high or low versions, are usb-c to lightning and must be used with a PD charger.

For users who have upgraded their old models, if they only have a usb-a charger at home, you can't even charge the battery. If you don't send a charger, you can make users consciously pay for the charger. Only apple dares to do this.

Regardless of this, let's talk about the quick charging of iPhone 12. The representatives of the small-scale avatar class have sorted out the current useful information, and you will get 99 points after reading the exam. 1、 Composition of iPhone 12 wired fast charging system

1. Interface


In 2012, Apple launched the lightning interface and took the lead in using it on the iPhone 5. The integration of front and back blind charging data makes the lightning interface lead the industry.

Today, however, whether it is the data transmission standard or the upper limit of power load, the Lightning interface has been surpassed in all aspects of the USB-C interface, USB-C has become the best configuration for most digital products, but Apple does not intend to replace the iPhone interface. iPhone 12 series still uses Lightning interfaces and enjoys the profits of private ecosphere and patents.

2. cables


iPhone 12 all-line standard cable upgrade from USB-A to Lightning to USB-C to LIghtning,, often called Apple fast charging, support PD fast charging, up to 20 W. powe

Cable skin material for TPE length of 1 meter, line body printed on the serial number. The Lightning terminal head contact is silver, the electroplating process is upgraded from gold plating to lao liao, and the visual effect of gold finger is silver. The direct benefit is that the electroplating effect is better, more effective to prevent sweat, liquid and other corrosion contact gold fingers, more durable.


The other end of the data cable is a usb-c connector. Use a macro lens to photograph the inside of the usb-c connector. There are 7 pins in each and 14 pins in total. The data rate is USB2.0 transmission standard.


The charging head of the whole iPhone 12 is cancelled, and the usb-c to lightning fast charging cable is used for the data cable, which is no longer compatible with the previous usb-a charger. Users need to use the charger with usb-c physical interface to charge normally.

3. Charger


The iPhone 12 series supports PD fast charging, and the attached charging cable is also usb-c to lightning fast charging cable. It should be noted that if a friend uses the former usb-a charging head (such as the right side), it cannot be used with the attached charging cable to charge the new iPhone. In the figure, the PD fast charging head based on usb-c output on the left side of the figure can be used, and it needs to support USB PD fast charging standard to trigger PD fast charging.

2、 How fast is the iPhone 12 fast charging?


Apple's website on the charging performance of the iPhone 12:


iPhone 12 power of the fast charging system has been raised from 18 W to 20 W, using Apple 18 original charger for iPhone 12Pro charging, with a power of 9.07 V 1.91A 17.38W, It can be seen that the iPhone 12 can be compatible with 18 fast charging.


Stolen the best match from iPad Pro Apple factory 20 W charger, for the iPhone 12Pro charge power of 8.91 V 2.18A 19.51W, successfully shake hands 20 W PD fast charge to full speed.


In order to test the maximum power of the iPhone 12, we use Apple 30W charger to charge the iPhone 12 pro with the power of 8.90v 2.49a 22.19w. It can be found that the peak power of the iPhone 12 Pro can exceed 20W. What is the difference between the charging speed of different powers?

In order to make a more intuitive comparison, Xiaobian tested Apple 5W usb-a charger, apple 12W usb-a charger, apple 18W usb-c charger, apple 20W usb-c charger and 65W usb-c charger. The data were drawn into the power percentage speed chart.


According to the trend of the bar chart, the 5W charger charges 18% in half an hour, 36% in one hour, and takes 3 hours and 25 minutes to fully charge. The 12W charger charges 44% in half an hour and 61% in one hour. It takes 2 hours and 13 minutes to fully charge the charger. Although compared with 5W, it is still very slow. Then there is the data of fast charging group. The charging curves of 18W, 20W and 65W PD are almost the same or even overlapped. In terms of speed, the charging rate is about 60% in half an hour, 88% in one hour, and it takes about 1 hour and 40 minutes to fully charge.

This speed in the industry level, small editor admitted that did not reach
