along with an important one that you

00:08

can't even see so in this video you're

00:10

going to see all of those new features

00:12

and changes and we'll also discuss the

00:14

performance the battery life and if you

00:16

should update or not first off we have

00:18

new emojis so these are some of the new

00:20

Emoji included in iOS 17.4 with Unicode

00:24

15.1 so some of these include a head

00:27

shaking forwards a head shaking from

00:30

side to side a phoenix a lime a mushroom

00:33

and a broken chain and there's also 18

00:36

additional people ody emojis so these

00:39

guys face right now and you could also

00:41

have different combinations for the

00:43

families with kids right here iOS 17.4

00:46

includes some major changes to the

00:48

podcast application so if I go ahead and

00:51

open up podcasts I will have

00:53

17.31 on the left 17.4 on the right

00:57

throughout this video so you can see

00:59

right away way some changes here so

01:01

first off in the top left you will

01:03

notice that listen now is now home and

01:07

also down in the bottom tab bar you can

01:09

see that listen now is now home in 17.4

01:13

and there is also a new glyph icon to

01:16

replace the play button and while down

01:18

there you might also notice that the now

01:19

playing bar is more like the Apple music

01:23

style so it's more of a floating style

01:25

it doesn't go edge to edge like it did

01:27

on

01:28

17.31 it also has has a lighter

01:30

background and it kind of just hovers in

01:32

place again reminiscent of Apple music

01:35

but the much bigger change here happens

01:37

inside of the now playing view when you

01:40

have a podcast playing and you will

01:42

notice down in the bottom leftand corner

01:44

we have a lyrics glyph icon and when you

01:47

tap on that that will pull up the

01:49

transcripts so now in 17.4 you have

01:53

podcast transcripts that play along in

01:56

real time with the person who is talking

01:59

in the podcast

02:00

very similar once again to what you see

02:02

with apple music and you'll notice that

02:04

after it's playing for a while you will

02:06

get a little search bar that pops up in

02:08

the bottom right there and you can tap

02:10

on that with an animation and you have

02:13

the option to find within that specific

02:16

transcript so if I want to find maybe if

02:18

they say sports at all you can see it

02:20

comes up four times and it will take me

02:22

automatically to where it says Sports

02:24

and if you tap on that specific spot it

02:26

will take you to that section in the

02:28

podcast and play it and you can see this

02:30

little animation here when you go out of

02:33

the search section back into the full

02:36

transcript right here so that is neat

02:38

also if you tap on the three dots up in

02:40

the top right you have a new option for

02:42

view transcript where you can see the

02:44

transcript as just plain text and you

02:47

also have a search button up in the top

02:49

right hand corner where you can search

02:50

for whatever you want and you can see

02:52

the UI the style of this is very similar

02:55

to the safari find on page and the great

02:58

thing about podcast trans descriptions

03:00

is that they can be used with

03:01

accessibility features such as text size

03:04

increased contrast and most importantly

03:07

voiceover and then if you go into your

03:09

library and go to latest episodes you

03:11

will notice that the glyph icons in the

03:14

menu up in the top right hand corner

03:16

have been removed because I think before

03:18

in

03:18

17.31 they kind of conflicted with the

03:21

check marks on the left hand side so

03:23

it's more clean now in 17.4 and by the

03:26

way Apple has made the Home tab cohesive

03:29

throughout iOS 17.4 not just in the

03:32

podcast application but also inside of

03:35

the books application so now instead of

03:37

read now it is now home and again up top

03:40

in the top left you can see that change

03:42

up there as well and also inside of

03:45

Apple music so in apple music instead of

03:48

listen now with the play glyph it now

03:51

says home with the home glyph and again

03:53

up in the top left that has changed as

03:55

well and speaking of music if you go

03:57

into the music recognition toggle and

03:59

you scan for a song that you didn't know

04:01

the name of and you use Shazam to pull

04:03

up this page right here there are a

04:05

couple of changes here as well so first

04:07

off you can see that the bar is a little

04:09

bit bigger here where it says Music open

04:12

and add to the text is larger and more

04:15

bold it's also more of a white color

04:17

also you can see the same for top songs

04:20

right there and also the top buttons up

04:23

here are now a darker color than they

04:25

were on previous versions of iOS also

04:28

when you tap on the three up in the top

04:30

right hand corner you can see multiple

04:32

changes here as well so now it says

04:34

listen in music instead of open and

04:37

apple music and now instead of add to

04:39

Apple music it says add to a playlist so

04:41

you can now add to a playlist from this

04:43

Ellipsis menu right here there's also

04:46

add to my music and more ways to listen

04:49

as a drop down right here and you could

04:51

also open it up in Spotify oh and also

04:53

the share button is now at the bottom

04:55

whereas before it was above view artist

04:58

also view artist is now goto artist so

05:01

multiple changes here in this little

05:03

menu also in the top left you can see it

05:05

does say apple music up there so there's

05:07

kind of like a title for this dropdown

05:09

and if you go down to the very bottom we

05:11

have some changes here as well so it

05:12

used to say track information in all

05:14

caps now it is no longer all caps same

05:17

with share song at the bottom used to be

05:19

in all caps and also bold now it is more

05:22

normal with a less you know weighty font

05:25

it's not as heavy and then right here we

05:27

have when it was shazamed and the

05:29

location so that was not even added

05:31

before on

05:33

17.31 and also I'm not sure if it's this

05:35

song or if it's just a change but the

05:38

colors are now different as well so it's

05:39

red instead of purple and we saw that up

05:42

at the top as well you can also now open

05:44

music in apple music classical if it is

05:47

available you can see right there it

05:48

says listen in classical before it said

05:51

open in classical and it was up top but

05:53

now music is the first option and

05:55

classical is second also in the Apple

05:57

music application if you go to the top

05:59

top pick section or if you go down to

06:01

made for you you will see a new heavy

06:04

rotation mix now this is a serers side

06:06

update it's not just for 17.4 but it

06:09

says the tracks you can't get enough of

06:10

lately all in one place updated daily so

06:13

it's going to take all the music you've

06:15

been listening to a lot lately and it

06:17

puts it into one playlist automatically

06:19

and it updates on a daily basis which is

06:21

really nice and that's something that

06:23

spotifi has had for a while but now it

06:25

is finally on Apple music by the way if

06:27

you want to get your hands on either one

06:29

of these wallpapers or the wallpaper

06:31

that you see on my home screen here I

06:33

will leave all of these linked down in

06:34

the description below now there's also

06:36

been a big change for the iPhone 15

06:38

series if you go into your settings

06:40

battery and then right here you'll

06:42

notice that it now shows battery health

06:45

and charging optimization separately so

06:47

before so I have my iPhone 15 Pro here

06:50

on the left 15 Pro Max on the right this

06:53

one's on

06:54

17.31 this one's on 17.4 you can see the

06:57

difference here before it just said

06:59

battery health and charging but now

07:02

those have been separated and when you

07:04

went into there before it would just

07:06

show this it would show your maximum

07:08

capacity it would show your Peak

07:09

Performance your charging optimization

07:12

and clean energy charging but now if you

07:14

go into battery health you'll notice it

07:16

shows multiple new things in here so it

07:19

shows the battery health as normal so

07:22

it's going to relieve a lot of people

07:23

and not make people as anxious when they

07:25

go into battery and they just see normal

07:27

right away most people are not going to

07:28

go into it and check that percentage

07:30

anymore so I think this is going to help

07:32

alleviate a lot of stress that people

07:34

have over their batter's capacity but

07:36

anyways also in here we have the cycle

07:38

count so this was found in the settings

07:40

General about before and then down here

07:42

we have manufacturer dates and also the

07:45

first use and iOS

07:47

17.31 that information was in settings

07:50

General about and then all the way down

07:52

here at the bottom and also cycle count

07:54

was below those two but now it's up here

07:57

and it also gives you a little bit more

07:58

information

07:59

on what the cycle count actually is now

08:02

what's interesting here is that also

08:04

underneath of battery health we have a

08:06

link right here that says about battery

08:08

and warranty and when you to on that you

08:10

get a little kind of a snippet of a

08:13

support document from Apple that tells

08:15

you that the original battery was

08:17

designed to retain 80% capacity at 1,000

08:21

Cycles under ideal conditions and apple

08:23

actually raised this from 500 Cycles to

08:26

1,000 Cycles because the iPhone 15

08:29

series batteries outperformed Apple's

08:31

original expectations so that is great

08:34

to see if you have an iPhone 15 series

08:36

and if we go into the charging

08:38

optimization section here you can see

08:40

there is a slight change here as well so

08:42

we do have clean energy charging down

08:44

there at the bottom whereas before that

08:46

was in the main section of the battery

08:49

health and charging not inside of

08:51

charging optimization so minor change

08:54

there this update also adds a much

08:56

needed change to the stolen device

08:58

protection feature feature that was just

09:00

introduced with iOS 17.3 so if you go

09:03

into your settings and face ID and

09:05

passcode and put in your passcode and

09:07

you scroll down you will see that stolen

09:10

device protection now has its own

09:13

section so before on 17. 3.1 it was a

09:16

standalone just an on or off button

09:18

right here and you couldn't really do

09:20

anything else but now in 17.4 it has its

09:23

own menu its own submenu here and from

09:26

here you'll notice a big change and that

09:29

is that you can now require a security

09:31

delay always not just when you're away

09:34

from a familiar location and if you

09:36

forgot what the whole security delay

09:38

feature is it basically just means that

09:40

like if you try to change your Apple ID

09:42

password and you're away from a familiar

09:44

location like your home or your work

09:46

you're going to have to have an hour

09:47

delay between face ID scans you have to

09:50

change your you know you have to put in

09:52

your face ID at first when you go to try

09:54

to change an Apple ID password for

09:55

example and then you'll have to wait an

09:57

hour and then put in your face ID again

10:00

you will not be able to use a password

10:02

to bypass the biometric scan of your

10:05

face so that is a great way to prevent

10:07

like a thief for example from stealing

10:09

your phone and you know draining your

10:11

bank accounts and changing your Apple ID

10:13

password because in that case they would

10:15

have to scan your face twice over the

10:17

span of an hour and that's just unlikely

10:19

so anyways that is when you're away from

10:21

familiar locations but if you want to

10:23

change that to always have that delay

10:26

now you can do that in iOS 17. four and

10:29

this is great because sometimes certain

10:32

locations would be considered a

10:34

significant location or a familiar

10:36

location like if you go to a gym every

10:39

day or if you go to a cafe every day

10:42

your phone might pick that up as a

10:44

familiar location so if somebody were to

10:46

steal your phone while you were working

10:47

out or while you were drinking a coffee

10:49

in the cafe your phone would register

10:52

that as a familiar location which would

10:54

mean that they would not have to go

10:56

through the whole security delay anymore

10:59

more they would just be able to change

11:00

your password right away now of course

11:02

they're still going to need to have a

11:03

face ID scan but they're not going to

11:05

need that second authentication and that

11:08

1 hour delay because you were at a

11:11

familiar location because again on 17.31

11:14

you did not have the option to always

11:16

require a security delay it only you

11:19

know happened when you were away from a

11:21

familiar location so hope that makes

11:23

sense this is a pretty complicated you

11:25

know feature to talk about here now iOS

11:27

17.4 is going to be perhaps the biggest

11:30

iOS update of all time for those living

11:33

in the EU because iOS 17.4 introduces

11:38

side loading so side loading is

11:40

officially live for those who live in

11:42

the EU now if you don't know what side

11:44

loading is basically that means that you

11:46

can install applications from thirdparty

11:48

App Stores so that is a thing that we

11:51

have always thought was never going to

11:53

happen on the iPhone but it's finally

11:55

here you could also set an alternative

11:57

app store as your default app store if

12:00

you would like to now this includes you

12:02

know we're going to start seeing app

12:03

stores from epic games to install

12:05

fortnite and you're going to see a lot

12:07

more of these alternative app stores

12:09

come out to those in the EU and

12:12

hopefully this does spread over to the

12:13

US eventually as well now side loading

12:16

is not the only thing that 17.4 ads

12:18

because there's also support for

12:20

third-party browser engines so Safari's

12:23

browser engine is webkit we all know web

12:25

kits but now Chrome can use its native

12:28

blink engine on iOS for the first time

12:31

and also thirdparty payment applications

12:33

and Banks now have access to the NFC

12:35

chip and can offer contactless payments

12:38

directly on the iPhone without using

12:40

Apple pay or the iPhone's Wallet app and

12:43

by the way if you are in the EU this is

12:45

a screen that you might see when you go

12:47

to install an application it says to

12:50

verify the information before installing

12:52

Google Chrome and this example now

12:54

something that has changed worldwide and

12:57

is not exclusive to the EU you is game

13:00

streaming applications are now able to

13:02

be included in the App Store and not

13:05

just in the browser so before

13:08

applications like nvidia's GeForce now

13:11

or Xbox cloud gaming previously you

13:14

could only access those through a web

13:16

browser like Safari but now they are

13:19

able to have their own Standalone app in

13:22

the app store which could mean that

13:23

you'll be able to get all those games in

13:25

one in the app store soon because 1.4

13:29

allows for it now if you go into the

13:31

account section in your app store you

13:33

will notice some changes here as well so

13:35

first off you can see that underneath of

13:37

our profile picture and our name we now

13:39

have Game Center so that is new and then

13:42

also under that we used to have

13:44

purchased subscriptions and

13:45

notifications but now we have apps

13:47

subscriptions purchase history and

13:50

notifications so you can go into here

13:52

and you can see all your apps that you

13:53

previously downloaded so before you had

13:55

to go to purchased and then my purchases

13:58

but now that is apps and my apps and

14:01

that's where you can see all the

14:02

applications that you installed and then

14:04

the purchase History Section is where

14:06

you can see all of the purchases that

14:08

you made in the last 90 days or you

14:11

could also tap on that and change it to

14:13

a different date range now in the intro

14:16

I mentioned how there's a big change in

14:18

iOS 17.4 that you're not going to be

14:21

able to see and that has to do with

14:23

imessage because iMessage is now more

14:26

secure thanks to Apple's new

14:28

state-of-the-art postquantum

14:30

cryptographic protocol for iMessage

14:33

which is called pq3 now pq3 is designed

14:36

to protect against Harvest now decrypt

14:39

later attacks where a bad actor collects

14:41

encrypted data with the hope of

14:43

decrypting it with a quantum computer in

14:46

the future now the messaging service

14:48

signal previously added a very similar

14:50

technique to their service but Apple

14:52

takes it a step further with what they

14:54

consider level three security compared

14:57

to signals level two now Apple achieved

15:00

level three by adding a quote periodic

15:03

postquantum rekeying mechanism that has

15:06

the ability to self-heal from Key

15:08

compromise so think of this rekeying

15:10

mechanism like a secret code that

15:13

changes regularly to keep your messages

15:15

safe so if a bad guy AKA a postquantum

15:18

computer that doesn't even exist yet if

15:20

they ever figure out your old code pq3

15:23

the thing Apple just introduced in 17.4

15:26

will create a new code that the bad Guy

15:29

cannot guess from the old one and what
