00:00:00,733 --> 00:00:02,033

The history of iPhone

2

00:00:02,500 --> 00:00:07,066

Apple has released many mobile phones since its first mobile phone in 2007

3

00:00:07,566 --> 00:00:12,033

The parameters, features and technologies used in each mobile phone are different

4

00:00:12,333 --> 00:00:13,300

In this video,

5

00:00:13,366 --> 00:00:17,233

we mainly explain the parameters of iPhone 6 to iPhone 8P

6

00:00:19,300 --> 00:00:21,766

If you are interested, you can take a look at this table,

7

00:00:22,000 --> 00:00:24,866

It doesn't have much significance for our actual maintenance

8

00:00:26,300 --> 00:00:30,233

We only talk about the characteristic and the new technology for each model

9

00:00:30,966 --> 00:00:34,200

The iPhone 6 is powered by Apple's A8 processor,

10

00:00:34,433 --> 00:00:37,566

which adds nfc function for the first time in this model

11

00:00:40,100 --> 00:00:45,800

In 6 plus, the camera has added optical anti-shake and landscape display for the first time

12

00:00:49,300 --> 00:00:52,633

The 6s series uses the A9 processor

13

00:00:52,700 --> 00:00:55,433

and adds the 3D Touch function for the first time,

14

00:00:55,633 --> 00:00:58,100

but there is almost no difference in appearance

15

00:01:04,366 --> 00:01:06,266

Let's take a look at 3D Touch

16

00:01:06,900 --> 00:01:10,900

After we press the icon on the screen, it will show a shortcut icon

17

00:01:14,666 --> 00:01:18,666

The 3D Touch function has been cancelled from the XR and above models,

18

00:01:18,666 --> 00:01:21,100

and Haptic Touch has been used instead

19

00:01:21,333 --> 00:01:25,466

The first generation of the iPhone SE was powered by the A9 CPU

20

00:01:25,866 --> 00:01:29,700

This model is the same size as the 5s and looks very similar

21

00:01:32,833 --> 00:01:35,766

It belongs to Apple's material consumption machine,

22

00:01:38,200 --> 00:01:41,433

because the 6 series is Apple's best-selling machine,

23

00:01:42,033 --> 00:01:47,000

Apple believes that the 6s series will continue the sales of the previous generation,

24

00:01:47,666 --> 00:01:50,533

so the materials prepared are very sufficient,

25

00:01:50,933 --> 00:01:53,300

but after the 6s series is launched,

26

00:01:53,400 --> 00:01:56,266

the sales are not as good as the previous generation

27

00:01:56,633 --> 00:01:59,166

This leads to a lot of inventory materials

28

00:01:59,300 --> 00:02:02,766

In order to solve the problem, Apple designed an iPhone SE

29

00:02:05,400 --> 00:02:11,900

This model uses 6s materials, such as CPU, hard disk, baseband, camera, etc.,

30

00:02:13,666 --> 00:02:15,866

but the screen uses 5s materials

31

00:02:17,000 --> 00:02:20,433

The iPhone 7 series uses Apple's A10 processor

32

00:02:21,900 --> 00:02:25,833

The iPhone 7 series supports stereo speakers for the first time,

33

00:02:25,833 --> 00:02:29,033

and cancels the 3.5mm headphone jack

34

00:02:29,300 --> 00:02:32,333

The signal of the headphone is converted by the usb port

35

00:02:36,266 --> 00:02:41,033

iPhone 7 series fingerprint becomes pressure-sensitive, not button-based

36

00:02:41,933 --> 00:02:45,533

The force of the finger pressing is converted into a vibration signal,

37

00:02:45,800 --> 00:02:50,333

which makes the vibration chip work to simulate the button feel of the early model

38

00:02:52,500 --> 00:02:53,800

In the picture, we can see that

39

00:02:53,766 --> 00:02:56,633

the reverse side of the fingerprint positions

40

00:02:56,633 --> 00:02:59,366

of 6 to 6sp model has a button ,

41

00:03:03,166 --> 00:03:06,600

but the positions of the 7th and 8th generation has no button

42

00:03:07,866 --> 00:03:12,800

It converts the pressing force into vibration through the pressure sensing chip on the cable

43

00:03:14,766 --> 00:03:16,933

The signal is connected to the motherboard

44

00:03:17,133 --> 00:03:19,633

iPhone 7p offers two rear cameras

45

00:03:20,666 --> 00:03:26,433

The iPhone 8 series is powered by Apple's A11 processor and adds a lot of new features

46

00:03:27,033 --> 00:03:29,966

The original color display is added for the first time,

47

00:03:29,966 --> 00:03:33,200

and the original color can make the screen display more beautiful

48

00:03:33,733 --> 00:03:36,066

We click the settings on the desktop,

49

00:03:36,133 --> 00:03:38,166

select the display and brightness,

50

00:03:38,433 --> 00:03:42,300

and you can see the original color display button in the current interface

51

00:03:45,866 --> 00:03:48,300

The iPhone 8 series also adds functions

52

00:03:48,300 --> 00:03:50,866

such as wireless charging and PD fast charging

53

00:03:52,066 --> 00:03:55,866

iPhone 8 and above all support wireless charging and PD fast charging,

54

00:03:55,933 --> 00:03:57,900

and all use glass back covers

55

00:03:59,100 --> 00:04:02,433

This is the introduction of iPhone 6 to iPhone 8P
