00:00:00,766 --> 00:00:03,533

In this lesson we're going to learn about the U1 chip

2

00:00:04,933 --> 00:00:06,433

In the mainboard of iPhone,

3

00:00:06,933 --> 00:00:09,633

the U1 chip uses ultra-broadband technology,

4

00:00:09,966 --> 00:00:12,533

so that the iPhone has the spatial awareness,

5

00:00:13,533 --> 00:00:16,266

in fact, refers to the positioning function

6

00:00:17,233 --> 00:00:19,366

If both phones have U1 chips,

7

00:00:22,100 --> 00:00:25,700

they can sense where the other phone is when they are in the same space

8

00:00:26,766 --> 00:00:32,333

In iPhones, the U1 chip will only be available on iPhone 11 or higher models

9

00:00:32,666 --> 00:00:36,600

Common iPhone functions like airdrop, Find my iPhone,

10

00:00:37,533 --> 00:00:41,266

or AR and VR, they all use the U1 chip

11

00:00:45,166 --> 00:00:48,533

The failure of the U1 chip is not common after it is damaged

12

00:00:49,066 --> 00:00:50,800

During the last repair,

13

00:00:50,866 --> 00:00:54,533

an iPhone 11 failed to wake up due to the U1 chip damage

14

00:00:56,766 --> 00:01:00,100

U1 chip surface is silver white, rectangular,

15

00:01:00,833 --> 00:01:03,366

generally in the vicinity of wifi

16

00:01:03,633 --> 00:01:06,333

Let's go to the real mainboard to know U1 chip

17

00:01:08,800 --> 00:01:11,033

This mainboard is the iPhone 11 mainboard,

18

00:01:11,400 --> 00:01:14,300

and its U1 chip is in the lower layer of the mainboard

19

00:01:14,566 --> 00:01:17,233

That chip is the U1 chip in the iPhone 11

20

00:01:20,466 --> 00:01:22,666

This is the 12 pro max mainboard,

21

00:01:23,300 --> 00:01:26,433

and its U1 chip is on the reverse side of the upper board

22

00:01:28,366 --> 00:01:31,366

This chip is the U1 chip of the 12 pro max

23

00:01:32,400 --> 00:01:34,533

So that's it for this lesson
