hi everyone aaron here for zollotech and
today apple released ios 15.4.1 to the
public this is available to all ios 15
supported devices just like all ios 15
updates so the iphone 6s 6s plus all the
way up to the 13 pro and 13 pro max now
this particular update was not a very
large one it came in at 313.2 megabytes
that's on my iphone 13 pro max and it
was between about 250 to 350 megabytes
on all the devices in this video
now as far as installing this if you're
not seeing it make sure you don't have
the beta profile installed if you are a
developer or public beta tester
otherwise just go to your settings go to
general then software update and check
for an update there if you're still not
seeing it turn off automatic updates
then check again and you should see it
now along with this update apple also
released ipad os 15.4.1 that i have on
the new ipad air fifth generation as
well as watch os 8.5.1
tv os 15.4.1 homepod os 15.4.1
and mac os 12.3.1 all of those have been
released to the public and are available
now now let's take a look at the build
number and talk about what's new so
we'll go to settings then we'll go to
general then about as you can see the
build number is 19e 258 and this
particular build was released to fix a
few bugs and add security updates now
the first thing that they have not
changed is a modem update there is no
modem firmware update in 15.4
but the first new thing or first thing
that they've actually resolved has to do
with battery if you're having poor
battery drain with ios 15.4 apple has
said specifically that they've resolved
that issue with 15.4.1
it says this update includes the
following bug fixes for your iphone
battery may drain more quickly than
expected after updating to 15.4 so
that's a concern quite a few people had
some people didn't update just because
they were hearing this elsewhere based
off a youtube community poll i did it
was great for some people and not for
others so it's great to see them
acknowledge this publicly and it's
finally resolved of course we'll have to
see what it's like after a few days as
well
now apple has also resolved additional
issues that have to do with
accessibility so maybe you're using
input devices such as braille maybe you
have a braille device that's connected
prior to this update it could become
unresponsive when navigating text or
displaying an alert so apple has updated
that for those that use braille devices
also made for iphone hearing devices
were having issues where they could lose
connection with some third-party apps so
that could do with bluetooth and other
things so they've resolved that in this
update so those things specifically for
accessibility it's great to see them fix
as far as additional fixes or bug fixes
they haven't mentioned anything
specifically but because they fixed the
issue with the battery it does make me
think they fixed the issue with music
where music would use additional cpu
and then cause battery drain so that was
something they said a long time ago and
it looks like it could be resolved this
time around so we'll have to see after a
few days if they've actually fixed it
but it does seem to be resolved as far
as the storage bug everyone has said
that that was fixed with 15.4 however it
can take a while to load for some people
again it should be resolved in this
update as i can't imagine they've
changed it but it can take a little
while to load so you'll see it is taking
a while to load so maybe it's changed a
little bit this is longer than normal so
it's the first time i'm running it here
let's run it on the iphone 10 and see if
we get the same result
so the storage bug you fix one thing
sometimes something else can happen and
it looks like it loaded so it did take a
while but it loaded and it has all the
information there system data isn't
showing just yet but it could take a
little while so just give it i don't
know 30 seconds or so and you should see
it pop up again there's no other issues
that they've mentioned specifically as
far as resolving but it seems like this
should be a solid update because it's
resolving that battery issue now apple
has also included security updates in
15.4.1
you can see this on apple's security
website and if we go down here a little
bit you'll see the latest versions of
the os's they've released so if we tap
on ios 15.4.1
we can see what they've resolved so
we'll just scroll down and it looks like
they only have one thing listed so it
says apple avd the impact was an
application may be able to execute
arbitrary code with kernel privileges
apple is aware of a report that this
issue may have been actively exploited
in order to fix it you'll see an out of
bounds right issue was addressed with
improved bounds checking so this is what
they've fixed in this update and it
looks like it's only one security update
at least that they've mentioned that
doesn't mean there's more that they
haven't resolved as well
in addition to this there's a few
different changes within the code thanks
to my friend steve moser that they've
updated preferences with different text
and things like that when restoring a
device so that's something they've
updated you won't see that and it's just
text so when you restore a device you
may see some changes there
other than that there's nothing else in
this and that leads me to should you
install ios 15.4.1
well if you were concerned about maybe
installing 15.4 because you were hearing
different issues regarding battery drain
and more well definitely install this
since apple acknowledges it specifically
this should resolve the issues with
battery as well as give you that
additional security update protection so
definitely install this if you haven't
already and of course then we'll see
what battery is like after a few days
when i do a follow-up on the weekend so
it will take a few days to know what
it's like i actually had okay battery
life just depends on the day but battery
was
generally pretty good for me so if we go
here take a look at yesterday i had five
hours and i used about 50 percent of my
battery so i was getting around 10 to 12
hours of screen on time with my normal
use so pretty good for me but not
everyone when it comes to the ipad it
also gets those exact same mentions as
far as the update within apple's release
notes they said that they fixed battery
and braille devices and hearing devices
as well so ipad gets those updates as
well and the ipad really struggled with
battery life for me so hopefully that's
resolved as far as overall performance i
really wouldn't expect it to be any
different so far it feels about the same
it's performing the same going into
music and scrolling and on any device
i've used it's basically the same
smoothness and i don't notice any
difference as far as that goes i'll
share with you the benchmarks in a
little bit though but as far as ios 15.5
betas some people have thought that
maybe we're not seeing any more ios 15
betas and apple will just focus on ios
16. however they've never done this in
the past but again they can change this
up whenever they want typically we'll
have updates all the way up until the
end of august where they'll update maybe
all the way to 15.7 with security fixes
and a few additional features if they're
not adding them in ios 16. so that's
normally what we see apple could be
changing it this year we don't really
know and you'll see it's the 31st today
and so typically we would expect already
to have a 15.5 beta 1 and be well into
the betas so maybe we'll have one next
week we could have one tomorrow apple is
really changing the way they've done
things and we haven't had an update in a
few weeks also we're still waiting for
wwdc invites the worldwide developer
conference happens every year usually in
june and they announce when they're
going to have it usually at the end of
march that's typically when they do that
although again it looks like they may
have changed it it's possible it will be
in person and typically it takes place
in the first or second week of june so
many people are suspecting the sixth or
seventh for wwdc and that's where we'll
see ios 16 and ios or ipad os 16 and mac
os 13 and so on so
those things should be coming up pretty
soon but we haven't seen those invites
just yet as far as benchmarks i did run
them on these devices just so you could
take a look and this is what i got on
the iphone 13 pro max it scored 1707
for single core
4705 for multi-core so i just wanted to
share that i'll run these again in the
follow-up video but i did run them on
all of these devices let me share those
with you quickly from left to right we
have the ipad air 5th generation
followed by the iphone 10 then the
iphone 11 and the iphone 13 pro max
these scores seem to be right where they
should be so basically if you're having
anything within a few hundred of these
you should have the same performance and
there's no issues whatsoever these are
just a general overview of what we would
expect for performance and they seem to
be at the higher end at least on the 13
pro max so that's everything with ios
15.4.1 and it's great to see apple patch
the battery issue and acknowledge it's
an issue for some people so it's great
to see them do that and fairly quickly
now i know it's been a couple weeks
since we had an update but it was nice
to see them patch an issue that many
people were concerned about now if you
found anything else i didn't mention in
the video i'd love to hear from you in
the comments below and of course if
you'd like to get your hands on this
wallpaper i'll link it in the
description like i normally do if you
