hello everyone icecooltech here now in this video we're going to be taking a look to see how the
iphone 7 handles the newly released ios 15.0 now is your iphone 7 experiencing battery drain
overheating yes well then that subscribe button below is certainly right for you by subscribing
with notifications enabled you'll free your iphone 7 from all battery drain and overheating alright
so kicking things off with overall performance i've noticed no change in general performance
coming from ios 14 on ios 15 with my iphone 7. performance overall is pretty much the
same like app launching times loading up web pages everything runs pretty much identical to ios 14.
uh the experience may vary by person but i will say in my experience pretty much no difference if
you're comfortable with the performance you're currently getting on ios 14 updating ios 15
you should be just fine so animations it's a little bit of a different story but not for
the worse animations like the iphone se and pretty much every other device i've actually tested ios
15 with the animations are so much more fluid than they were with ios 14. for example the app library
and widgets page stuttering is finally been eliminated and i'm really really happy about that
all other system animations including the control center the notification center and all scrolling
through our apps everything is just really smooth now ram management on the other hand is not the
best actually it's taken a noticeable hit from ios 14 but keep in mind the iphone 7 does only
have two gigabytes of ram if you have a seven plus you'll have the three gigs but the iphone
7 here only has two gigabytes of ram so it's not really as much compared to newer iphones
alright so before i talk about battery life really quickly i do want to just mention that
my iphone 7 currently has a maximum capacity of 89 and is running at its peak performance
all right so since updating ios 15 battery life has been roughly the same during usage
as it was with ios 14. you can actually notice too that my battery is going down
while recording this video but again the same applied to ios 14 as well even ios 13. it's not
till we talk about standby time that we actually notice a big difference standby time has horrible
battery drain on ios 15.0 i'm noticing a drain if i kid you not 49.5 overnight which is a problem i
would say and we hope to see a fix soon i'm taking a look at overheating um ios 15's been pretty good
occasionally i'll notice the phone getting very slightly warm but other than that it's nothing
excessive compared to ios 14 or even ios 13. again performing graphical intensive games or tasks
will likely result in more overheating but that's only natural after all so it
does look like we have some improvement with ios 15 and that is always really nice to see
now keep in mind that you will likely experience more battery drain overheating and even possible
performance decreases the first few days so about 1-30 days after updating to ios 15
this is completely normal you just have to let the phone finish all the background tasks that it
needs to perform post update so now we're brought back to the main question of should you update so
there is no definitive yes or no answer however i can provide suggestions so if there's an app that
you need on your current ios release or maybe a new feature in ios that you absolutely need then
i would say it's in your best interest to update however if you are currently still on maybe ios
12 ios 13 or even ios 11 or earlier and you are perfectly happy where you currently are and there
is no need to update i would suggest staying there alright everyone that is all i have for this video
