hi everyone Aaron here for ZolloTech and today Apple released iOS 12.4.1 this is available to everyone everyone that has an iPhone 5s
or later and iPad Aaron later can install this as well as the iPod Touch
6th generation it came in at ninety nine point three megabytes on my iPhone 10
and a little bit over 100 megabytes on my iPhone 8 plus let's take a look at
the build number the build number is 16G102 and this particular build is
really only there to address one major issue and that has to do with the iOS 12
point for jailbreak you can no longer jailbreak with this particular update so
I would suggest against that if you're going to I would suggest against
updating if your going to want to jailbreak now if you're on iOS 13
already it's not easy to install this you actually have to downgrade so I have
a separate video on how to do that and if you want to do that you'll have to
actually use iTunes to downgrade you can't just delete the beta profile if
you're on one of the betas and expect the update to work it doesn't work like
that so you will have to use iTunes now as far as any of the information
regarding this particular update Apple just says a malicious application may be
able to execute arbitrary code with system privileges so basically a
jailbreak and it says use a use after free issue was addressed with improved
memory management so there could be improved memory management as well along
with that code but that's really all there is in this this is a very small
fix for the jailbreak and security so they highly recommend you install this
but also I wanted to talk about battery life performance Geekbench in iOS 13 so
as you can see performance is okay on the iPhone 8 plus swiping is fast the
same is true on the iPhone 10 landscape seems to work just fine no issues there
and 3d touch that you know and love is still there unlike the way it works on
iOS 13 so it looks pretty good and it's working well now aside from that battery
life many people were saying battery life was good and then others were
saying it was so good on iOS 12.4 hopefully it's fixed
on this particular device I have a 97 percent battery health but I haven't
been using it other than just today for a little bit while doing this video I've
been using iOS 13 to be honest so hopefully it improves either way it
takes a few days and I'll do a follow-up to checkup and see how it's going after
a few days and maybe run a poll if you want to see that let me know in the
comments below but maybe you run a poll about iOS twelve point four point one
now as far as the Geekbench scores are concerned I did run it on both of these
devices and on the right you'll see the iPhone 8 plus has ten thousand six
hundred and thirty nine for multi-core 4234 for single core on the Left we have
the iPhone ten with very similar scores they are running the same processor 4269
for single core ten thousand six hundred and forty for multi-core now if we take
a look at the actual history on the eight plus since I've run it before it's
actually gone down a little bit I did run it a couple times before and it
seems like it went down slightly but the actual performance doesn't feel any
different so it's probably fine to install but just keep that in mind now
also Apple released watch OS updates as well as Mac OS and Apple TV updates and
with that Mac OS update I would definitely install it as it has to do
with fixing some speed issues when you're working with larger files so keep
that in mind also now iOS twelve point four point one is probably the last
version of iOS 12 unless there's a major security issue in the future that
affects older devices and I say that because iOS 13 devices should be getting
an update soon and the 5s the 6 and the 6 plus don't support iOS 13 so if you
have an iOS 12 supported device but not 13 we probably won't see another version
of iOS 12 unless there's security vulnerabilities I would expect iOS 13
however in the second week of September second or third and then we'll just have
iOS 13 from here on out on all of our devices and that one's looking pretty
good of course I have a bunch of videos about that as well but I think twelve
point four point one maybe at the very last unless
see a major security vulnerability for older devices so that's really it with
this particular beta there's not much more to say if you'd like me to do a
follow-up let me know in the comments below but other than that I'll link this
