Hi everyone Aaron here for Zollotech and today apple released ios 15.2 rc2 this is
available to developers and hopefully public beta testers by the time you're watching this video
and a release candidate is the final version of the update that should release to the public
should there be no other issues found and so with the release candidate 2
apple must have found an issue and then released this update and this came in at 391.2 megabytes
that's on my iphone 13 pro max now apple did not release this for any other devices other than
iphone 13 series phones so iphone 13 iphone 13 mini iphone 13 pro and iphone 13 pro max they
didn't release this update to any other phones and they only released one other update along
with this update and that is mac os 12.1 rc2 so they didn't release an ipad update a watch update
or tv update just ios 15.2 rc2 for iphone 13 pro and 13 series in general now let's talk about
the build number and then talk about what's new so we'll go to settings then we'll go down to general
then about you can see the build number is 19c57 and the previous build was five six or what people
currently have if you don't have a 13 device with the latest update on it and in this particular
update there is one change that i was able to find and that is to the modem so under about you have
a modem update on the 13 series devices and i would think that this has to fix the issue with
switching between 5g and the reason i say this is i was placing a facetime call earlier this week
when i was on rc1 placing a facetime call and when switching between 5g uc and regular 5g
the call would just drop when i forced it to go to lte or 4g it worked just fine so there's an issue
between switching i don't know if it's resolved just yet but it looks like i'm picking up uc here
without a problem and my data is working okay so going into things like music maybe going to browse
it seems to be working okay when i'm on uc although sometimes it's a little bit slow as
you can see here so there's definitely some issues with the modem now this is specific to t-mobile
with uc whether or not it's affixed on say a t or verizon or other places it's hard to say as
it takes a few days to know if that switching's fixed however you did see that it loaded but it
took a while so maybe it had to switch and apple's working on that issue as far as any other updates
well i haven't found anything else and i even have my friend steve mosher take a look at the code
and it does not appear that there's any major changes in this update with rc2 it looks like
it's just a fix for the modem and maybe some additional bug fixes that they didn't mention
but other than that there does not seem to be any features or changes or anything else that
anyone's been able to find it seems to be just related to that modem update as far as i can tell
so they typically find something major and push in rc2 however they normally push it to all devices
so this is the first time i think we've seen in a very long time where they only push a release
candidate to a few devices it's a little bit different and again it's available to mac os
as well now other than that i did have some issues that i was going to mention in the follow-up
later this weekend and typically i run a youtube community poll where i ask how it's going for you
so this will still pertain to rc2 as well but in general we'll just comment here and then
i'll use that information to do a follow up a little bit later with more information on
how it's going and whether or not it should be ready this coming week and as far as any other
issues i was having with it i had settings lock up on me where it completely froze already on rc2
or on rc1 hopefully rc2 fixes it and also i had an issue with google smart lock i've mentioned
this before with the app and when it triggers bluetooth it seems to crash the app has not
been updated in about six months so maybe google needs to update that app but it allows you to log
in with two-factor authentication to google services so hopefully they update that as it
does not seem to work at all at least on 13 series devices with with smartlock and that app with the
latest version of 15.2 so hopefully they fix that now also regarding bugs apple does mention in the
notes that there are known issues with streaming music that could result in higher cpu usage
and cause faster battery drain this has been there for a few betas and still remains in rc2 as well
so it doesn't look like they've fixed that in this particular update as they still mention it
so that's there unfortunately hopefully they'll fix it in maybe ios 15.3 now as far as when to
expect 15.2 well based off what they did last year with 14.3 i would expect to release either on the
13th or the 14th last year they released it on the 14th so that was a monday last year though so we
either could see at the 13th or 14th released to the public and be available to everyone else
and then typically they'll switch to a new beta after that last year we got it on the 16th which
again was a wednesday so maybe we'll see a release on the 13th with a new beta maybe ios 15.3 beta 1
on the 15th or 16th i would expect something along those lines as it seems to make a lot of sense
now as far as battery life i wanted to share my current battery life and also performances i did
run a geekbench test on this as well my battery health is at 100 on this device it's only a few
months old though so that makes sense and over the last 10 days we'll take a look at yesterday i had
two hours and 50 minutes of screen on time 7 hours and 12 minutes of screen off time playing music
the day before 4 hours and 20 minutes 5 hours and 58 minutes of screen off time and 50
of my battery so i'm easily getting through a day typically by the time i go to bed i have over 50
percent of my battery life left and i really don't think about it it does really well with these
updates i think the rc is much more stable and performance seems to be pretty good other than
that lockup i mentioned on rc1 i haven't had that here so it seems to be pretty good now as far as
the benchmark scores we'll go into geekbench 5 and i did run it twice just to see if it would be any
different and i scored 1730 for single core 4754 for multi-core if we take a look at the history
here we'll go back go to the history and you'll see today we'll scroll down here december 10th
you'll see the different scores so we had 1730 which is a little bit higher than we had with rc1
so i ran it a couple times there and then 4754 again higher than previous versions other than
maybe beta 4 which seemed to be a little bit higher with multi-core but that was
after a few days since this is just out that's pretty impressive i think now after running the
benchmarks and everything else the phone does seem to stay nice and cool so i really haven't
had any issues with the phone getting hot or having any issues with it getting too warm
although it does heat up normally when doing intensive tasks it seems to be doing just fine
and so that's really everything in this update hopefully we'll see it released to the public
here in a few more days earlier next week and then we'll move on to a beta after that but let me know
if you've found anything else in this particular update i'd love to hear from you in the comments
