00:00:00,766 --> 00:00:04,166

In this video we're going to learn about the wireless charging chips

2

00:00:05,433 --> 00:00:06,833

In the Apple models,

3

00:00:07,233 --> 00:00:12,900

the wireless charging chip mainly functions to convert the power supply received by the wireless charging module

4

00:00:12,900 --> 00:00:15,333

into the voltage required by the charging chip

5

00:00:19,266 --> 00:00:20,733

In Apple models,

6

00:00:21,333 --> 00:00:24,766

wireless charging is only available on the iPhone 8 or above

7

00:00:25,933 --> 00:00:29,933

That's why we find wireless charging chips in iPhone 8 and above

8

00:00:31,466 --> 00:00:33,566

When the wireless charging chip is damaged,

9

00:00:33,800 --> 00:00:36,666

the common failure is that it cannot be charged

10

00:00:36,933 --> 00:00:39,900

Replacement needs to be replaced with the same model,

11

00:00:40,466 --> 00:00:44,133

but the probability of the chip damage is relatively small

12

00:00:45,933 --> 00:00:48,900

Most users are not using the cwireless charging

13

00:00:50,866 --> 00:00:55,733

The wireless charging chip is a rectangular glass crystal with a silver-white surface

14

00:00:58,733 --> 00:01:00,300

In the dual-layer mainboard,

15

00:01:00,800 --> 00:01:05,033

the wireless charging chip is generally located in the lower layer of the mainboard

16

00:01:05,666 --> 00:01:10,366

For other models, the wireless charging chip is usually located near the charging chip

17

00:01:12,100 --> 00:01:15,600

Let's go to the physical mainboard to check the wireless charging chip

18

00:01:17,433 --> 00:01:20,100

This mainboard is an iPhone 8p mainboard,

19

00:01:20,300 --> 00:01:23,066

and its wireless charging chip is in this position

20

00:01:23,800 --> 00:01:29,200

This chip is the iPhone 8p wireless charging chip, rectangular glass crystal

21

00:01:30,966 --> 00:01:36,166

The mainboard is an iPhone XR mainboard with a wireless charging chip underneath the hard drive

22

00:01:38,333 --> 00:01:40,100

This chip is inside the shield

23

00:01:40,266 --> 00:01:43,300

We can see it only after the shield is removed

24

00:01:44,400 --> 00:01:47,700

This chip is the wireless charging chip in the XR model

25

00:01:49,500 --> 00:01:51,366

This is the iPhone 11 mainboard,

26

00:01:51,600 --> 00:01:54,766

and its wireless charging chip is in the lower part of the mainboard

27

00:01:56,666 --> 00:01:59,700

This chip is the wireless charging chip of iPhone 11

28

00:02:00,500 --> 00:02:03,566

It has a larger chip than the XR and 8 models

29

00:02:05,533 --> 00:02:07,700

So that's all for this lesson
