hi everyone Aaron here for zollotech and today apple released ios 15.4 beta 4.
it's now available to developers and hopefully by the time you're watching this video it will
be out to public beta testers as well however last week it came out the following day with
beta 3. so if it's not out a little bit later today expect it tomorrow now this update came
in at 579.2 megabytes that's on my iphone 13 pro max and it was between 400 and 600 megabytes on
all the devices in this video from the iphone 6s plus iphone 11 iphone 10 ipad pro and 13 pro max
apple also released ipad os 15.4 beta 4 watch os 8.5 beta 4 tv os 15.4 beta 4 and mac os 12.3
beta 4. all of those are available to developers right now and again probably a little bit later
to public beta testers now let's go ahead and take a look at the build number and talk about what's
new so we'll go to settings then general then about you can see the build number is 19e 5235
and when we have an a at the end that typically means we're getting very close to a final release
so i would expect a release candidate next or rc followed by a final release after that i'll talk
about when to expect that a little bit later on now the first change they've made in this is a
modem update so there is a modem update prior to this we had 1.59.00 now we have 1.59.03 at
least on the 13 pro max so i really wasn't having any connectivity issues in this update between 5g
5g uc or 4g or anything like that but if you are hopefully this will continue to resolve
those issues for you now the first change they've made or feature that they've added is if we go
into settings and then we go down to syrian search under sirian search go to siri voice
you'll see under american we have a new option now for voice five so this is something they've added
in this update let me turn it up so you can hear it so voice four is typically what we have hi i'm
siri choose the voice you'd like me to use voice 5 is a little different hi i'm siri choose the voice
you'd like me to use listen to that one more time hi i'm siri choose the voice you'd like me to use
so you can hear there's a new voice option if you want to choose that i did not find any other
options under australian british indian irish or south african yet so maybe we'll have updates with
that with further updates with the release candidate or more now there's an additional
feature or change when you pair an air tag so if you have an air tag and you pair it to your device
what it looks like is this so it says air tag is linked to your apple id now it says air tag
is intended solely to track items that belong to you using air tag to track people without
their consent is a crime in many regions around the world air tag is designed to be detected by
victims and to enable law enforcement to request identifying information about the owner so that's
just a new message that they've added with this update and then within the update here you'll
see it gives you more information about precision finding play a sound and notify when left behind
additionally there's some new options for find under settings so if we go under settings
and we scroll down we'll go to or scroll up to notifications scroll down to find my
you'll see it just says find my if we look at beta 3 or previous versions
it actually is a little bit different so again notifications go down you'll see we have find
my and find my safety alerts you can no longer disable find my safety alerts to let you know
that there's an air tag nearby so they've made some changes there with additional customization
within the find my notification settings so you can customize this how you'd like so
that's been updated in beta 4. additionally under the watch app they've made some changes as well
so in watch if we go to watch and then we go down to mail find mail under mail there's a new option
for always load content directly so this is applying to the watch it will load it directly
if you want it to also you'll see here at the top where it says hide ip address this is part
of icloud plus where you have to have it enabled if you have icloud plus to hide your ip for mail
prior to this update it did not hide your ip address on the watch only on the iphone so now
it will hide it on the watch and you'll see it says hide ip address if you turn it off under
icloud plus it will switch to show ip address so that's something they've updated as well
there's also more code in here for tap to pay setting that up under wallet where you're able to
maybe have someone pay you via credit card tapping the nfc chip on the back to pay you that way so
that's something that's going to be coming out with 15.4 it seems but there is no option to
enable that yet that i could find but it should be in this update now there's also code changes
within here there's updates for notifications and captive wi-fi and again thanks to my friend steve
moser for pointing that out to me and helping me find some of the things i've already mentioned
as well so you can see here customize find my notifications and some features and find my
require notifications and then apple is continuing to work on captive network support for apple tv
with new bluetooth permissions copy for british english bluetooth used for proximity setup so you
can see some of that code here as well now as far as resolved issues in this update there's
only one that they mention in the notes and that has to do with on ios and mac os it's possible to
trigger taking a photo of a participant when in a group facetime call they fix that bug you can
no longer do that before you could do that easily by tapping the bottom left corner of the screen
and on mac os you could do that by tapping the right top right corner of the window so that's
something they've fixed in this update and you shouldn't see they haven't mentioned any
other fixes but in beta 3 we saw the storage bug seemingly be resolved so i haven't seen that bug
here it looks like it's loading nice and fast i went back in it and it takes a second to load but
nothing like it did before where it could take 30 minutes or even longer or just never load you'll
see it even loaded system data quickly and most people are saying this was resolved with beta 3.
if it's not i would check it with beta 4 but it seems to be resolved for most people in this
update if it wasn't in beta 3 already apple did not mention anything about the pink screen bug
where it could go pink or purple and then reboot the phone however it does seem that they fixed it
in beta 2 or beta 3 but again they didn't mention it maybe they will by the time it's released
there's also no mention of the music bug where maybe you're playing music and streaming that
music causes the cpu to be used a little bit more and then in turn causes battery drain again they
didn't mention that however they did mention 12 known issues which is down from 13 the previous
week and there's a few notable issues but they're basically the same as what was there before
one of them again being signing into an ipad is limited to apps in this beta so there's some odd
issues here and there that they're still aware of that they're working on with health and more
as far as when to expect ios 15.4 rc or release candidate we could see that as soon as either
the end of this week or early next week around tuesday or so that's typically what apple does
and since we expect an apple event around the 8th of march which we would probably see an invitation
either any day or probably next week at this point it seems likely that apple would release 15.4 to
the public around the 8th that will include new emoji and much more that's in this update so a
lot of different changes in this update not only with find my emoji but there's some other nice
things with tap to pay and more of course there's that face id unlock with a mask as well included
in this so expect it within the next couple of weeks an rc in a final release and then we'll
move on to maybe 15.5 betas i did think we'd maybe have an ios 15.3.2 but seeing how we're a couple
weeks out from 15.4 that seems unlikely at this point however apple did unsign 15.3 the other day
meaning that there should be an update coming very soon so it's possible we see this earlier
than the 8th but at this point that's kind of what i'm counting on as far as battery life in this
particular update well it will take a few days to know that and i typically cover that towards
the end of the week or on the weekend with a follow-up video but battery life with beta 3
and 2 and earlier ones was not that great my battery health on my 13 pro max is 100
and if we go back to yesterday you'll see i had three hours and 35 minutes of screen on time 5
hours and 49 minutes of screen off time and i used about 60 of my battery 50 to 60 percent
so that's not great i should be getting 10 to 14 hours of screen on time with this particular
device again today if we go to today even after updating i only use 25 of my battery but again use
two hours and 46 minutes of screen on time five hours and three minutes of screen off time and
i've hardly used it so it's using quite a bit in the background instagram is using a lot for some
reason and i'm not sure why since i've hardly used it so that doesn't make a whole lot of sense to me
now as far as overall performance so far it seems good on the 6s plus i tested it out here
and it seems to be performing pretty well so just after reboot it was fine and you'll see
this is the first time loading music takes just a moment here and that's some of that has to do
with wi-fi and pulling down the information but it does seem generally smooth for what this device is
and then if we go into minecraft and i've talked to some of you about maybe showing
a different game but let's just see how it resumes so we'll give it just a moment
ram management i would expect to be the same but if we resume the game that was pretty fast
especially on one of the oldest devices here or the oldest device here but one of the oldest
supported devices you'll see frame rates are nice and smooth so that's really what we're looking for
and it seems to be pretty reasonable as far as overall performance as far as benchmarks are
concerned i did run benchmarks on a couple devices here but i want to save most of that information
for the follow-up video since we want to give it a few days for things to finish processing in the
background you'll see here for single core i had 1734 for multi-core 4645 if we compare that to
the weekend follow-up you'll see it's a little bit lower but when beta 3 released on the 15th
you'll see it's actually a little bit higher so as long as we're within 100 plus or minus
it should be running just fine but again i'll show you more details about that in the follow-up video
this weekend the overall heat of the device they stayed pretty cool after rebooting so no issues
there it was nice and cool on all of these devices which was a little pleasant surprise typically
they're quite warm that shouldn't really affect much but it's nice to have it sort of managing
thermals a little bit better and then that also leads me to should you install ios 15.4 beta 4.
and typically at this point we're at probably one of the last if not the last betas until the rc
i would say you could definitely try it just make sure you have a backup and of course if you're on
beta 3 definitely update beta 4 since you'll have a better experience typically you'll get more bugs
worked out and hopefully it's just performing and basically ready to release to the public so i'll
have more information about that as i know more about the update so that's everything in ios 15.4
beta 4. of course if i find more features i'll have a new features video at the end of the week
and a follow up with all the different things as far as stability battery life and more like
i normally do on the weekend of course if you've found anything else i'd love to hear from you
in the comments below and if you'd like to get your hands on this wallpaper i'll link it in the
description like i normally do if you haven't subscribed already though please subscribe and
