hi everyone Aaron here for zollotech and battery health is something i get asked about
every single day in fact it seems more and more people are asking me about it
and about two to three people will message me every single day either direct message or
through email and even more will comment about it asking about battery health whether or not they
should worry about it how to maintain it and more now i have videos in the past where i've talked
about this but things have changed a little bit with ios since i last made those videos battery
technology has changed a little bit so i wanted to talk about that i thought we'd cover what battery
health is what my phones that have been used full time currently have so i have an iphone 6s plus an
11 pro max a 12 pro max and my 13 promax that i've used full time charged them all the exact same way
and wanted to share what that's like and also how you can maintain it and how to check it on devices
that may not have it so such as the ipad air now the first thing is what battery health actually is
battery health is measuring the capability of the battery based on when it's new
versus what it is after you've used it for a while so on the 13 pro max we have a 4 352 milliamp hour
battery and say you've used it for a couple of years maybe we get down to 500 milliamp hours left
another example would be maybe you have a car that you just got it holds 10 gallons of fuel or petrol
or gasoline depending on where you live and after using it for two years it now only holds eight
gallons and so that's the same sort of thing of what happens to batteries batteries degrade
over time and based on how much they've degraded apple gives you a percentage of what's left and so
currently on my 13 pro max you'll see i'm at 100 percent you can see that in your battery settings
which you're probably already familiar with but battery and battery health you'll see your battery
percentage there and over time this is going to go down there's nothing you can do currently with
the current capabilities of batteries and the way they're actually produced to actually make them
extended a hundred percent for the life of the phone or anything else batteries degrade over time
and until someone invents a better one there's really nothing you can do unfortunately whether
that be an iphone an android phone a car such as a tesla or anything else they just degrade based off
the way they work actually by charging them they expand and contract and heat affects them as well
they can develop micro fractures that just degrade them over time and then they will eventually need
to be replaced so maintaining them is something the phone is going to help you do but there's a
few things you can do as well now first i wanted to answer a few questions that many of you had
so the first thing is a little bit of a myth based off of these batteries lithium ion batteries do
not have a memory or not a memory similar to what we had with older nicad rechargeable batteries
or nickel cadmium and the reason for that is it's just the way they work and what that means is you
don't need to charge it when it's brand new or drain it to zero percent so maybe you have a
brand new phone i get asked all the time do i need to charge my phone to 100 before i use it
or do i need to drain it to zero and let it turn off before i can use it and you absolutely do not
need to do that apple calibrates them at the factory tells them the capability of the phone
such as the three 4 352 milliamp hours and it knows based off the battery management system
what it's capable of then it will change over time now there is an exception if maybe you replace the
battery with a non-apple battery you want to calibrate that battery to your device the only
way to calibrate that or for the computer to learn it is drain it down and charge it all the way up
otherwise if it's an apple battery or you just got it from apple you don't need to do any of that
another question someone had is does low power mode affect battery health and it doesn't affect
battery health but it affects battery or your phone performance so if you turn on low power mode
you're going to gain some battery life because it's turning off features meaning your battery
will last longer it's really designed to maybe get you to a charger when you don't have one nearby
so maybe you're down to 20 percent you won't be home for a while or you won't be near a charger
you need to extend the battery then you can turn it on but by turning that on you're reducing the
performance of the processor it's going to turn it down a little bit it's also going to
turn off features such as mail fetching mail and all sorts of other things it will also make sure
auto brightness is turned on and much more so just keep that in mind that if you are using low power
mode you're going to lose features i typically recommend against it unless you can't get near
a charger soon also another question i get a lot is do ios betas degrade your battery faster and a
lot of people say well i just installed a beta or an update and my battery health went down that's
only because it's measuring your battery health so what it's doing is it installed an update and
it says let me see what it's at now so you may see it vary and it could go back up a little bit
later as it learns the battery and recalibrates but typically over time it will go down but the
updates themselves do not degrade the battery however they could use more battery meaning that
the battery life of your phone might go down a little bit since you're using beta software that's
not available to the public and it could have some bugs in it and things so it doesn't affect the
health other than you may charge your phone more often which in turn degrades the health however
using just beta software or software updates in general does not do that as far as how i charge
and what i've done to maintain my battery health well first let me show you my battery health so
settings battery health on my 13 pro max i've used this every single day just about since it was new
with the exception of reviewing a couple other phones it's at 100 percent on my iphone 6s plus
this is an older phone which has been maintained similarly but if we go to battery and battery
health i use this for an entire year full time i'm at 85 percent so that's pretty good given its age
then if we look at the 11 pro max the 11 pro max again used for an entire year is at 93 percent and
this is actually recalibrating it so this could vary it could go up or down a little bit and then
on the 12 pro max again that i used for a whole year as my main phone go to battery battery health
i'm at 94 percent so after a year or so typically you can expect about 10 percent to go down but
apple says after two years you can expect around 80 capacity that's completely normal depending on
your usage if you're a very heavy user and you use the battery a ton charge it a lot and discharge it
a couple times a day it's going to go down more quickly it's just the way the battery is but as
far as charging and how i charge well this is a bit controversial depending on who you ask
scientists that study batteries will say optimally you want to keep your battery between about twenty
and eighty percent all of the time other scientists will say leave it at a hundred
percent it just depends who you ask so since the first iphone i've charged them all the exact same
way i've owned every iphone and i've charged them the same the first iphones i used a 12 watt apple
charger from the ipad with it it's not really a fast charger but it was the fastest way to charge
at the time i would plug it in at night go to bed wake up in the morning take it off of the charger
when i was in my car i'd plug it into apple carplay when that was available or just my stereo
use it then it would be charging then i'd get to work or wherever i was going unplug it and i would
use it then then in my car i'd put it back on when i got home i'd put it on the charger before
i go to bed so nowadays with a magsafe charger i put it on a charger on my nightstand at night
charge the battery and go to bed when i wake up it's fully charged apple is now managing this for
you and holding it 80 with optimized battery charging and it says to reduce battery aging
iphone learns from your daily charging routine so it can wait to finish charging past 80 percent
until you need to use it meaning maybe you have an alarm set to wake up at 7 00 am you set that
alarm and by the time it's 7 am it will be at 100 however before then it will hold it at 80 percent
until it gets close enough to the time it needs to start charging again to reach 100 percent by the
time it's time to use it this helps extend battery life over time so apple is using the 80 percent
measure to actually help you extend it over time now some people say will you overheat the battery
will you maybe overcharge the battery and you cannot overcharge the battery it's impossible to
overcharge the battery as there's circuitry in the battery to prevent that from happening on iphones
so even if you give it a different battery charger such as this nano 245 watt from anker
you're charging it you plug this in the phone will only allow you to deliver the amount of
power that it needs so maybe it's capable of 20 watt fast charging it will only allow
20 watts to pass even though the charger is capable of more the phone manages that for you
and prevents the battery from either getting too hot or charging too much so many people say well
fast charging makes the phone too hot and apple is actually very aggressive at managing heat in the
phone there's sensors in the phone to manage that temperature and as you're fast charging
whether that be with magsafe or directly with a lightning cable the phone actually says it's
too warm and it will reduce the amount of voltage or wattage going into the phone to make sure that
it doesn't get too hot it does that on its own and apple actually has programmed it to do that
so it will manage the voltage and wattage going into the phone or wattage going into the phone to
make sure that it's not 15 watt fast charging if it's getting too hot it will pull it down to maybe
10 watts or 8 watts you can see this in previous videos i've made where over time it will actually
reduce the power then it will go back up so that's something that they've been very good with also
that happens in their mag safe charger as well so they're just measuring this depending on what
charger you're using measuring it to make sure it's optimal now if you have a case on your phone
it may get too hot and even charge slower so maybe sometimes if you're in a very warm environment
apple actually recommends removing the case so that doesn't happen so it doesn't get too hot
and it will charge at its fastest speed and they can manage heat a little bit better now
if you're someone that's trying to maintain the battery between 20 and 80 percent all of the time
and being careful when to plug it in or unplug it you really won't see much of a gain in my tests
maybe three percent over the period of a year and so that's something that i typically don't
recommend to people now if you're wanting to see battery health on an ipad the only way to do that
is with a utility on your mac or your windows computer i'm using coconut battery on a mac and
you can see here it shows the design capacity it's at 100 percent and more importantly i think it's
showing the cycle count a battery cycle is a full charge and discharge or any combination in between
meaning a hundred percent to zero and back up to a hundred is a cycle or maybe you're at fifty
percent you charge to one hundred percent then the next day you're down to fifty again and charge to
a hundred that fifty percent discharge twice equals one hundred percent that's a full cycle
so any combination of that twenty percent all the way up to a hundred and the next day eighty to a
hundred that would give you a full cycle so that cycle count is kind of a finite number as to when
it degrades usually around a thousand but it varies depending on device now one tip is maybe
you need to replace the battery or maybe you think you do you can go to apple's support app now that
they've updated with some very helpful features so you'll see there's repairs and physical damage
then you can tap on battery service and it will actually check battery performance for you it
says run a quick check to see the health of your battery you'll also get performance tips based on
your settings and more help if the battery needs service if we tap on check now it will check the
battery and you'll see it says maximum capacity 85 performance is normal maximum capacity is 80
or higher and peak performance is normal see a few tips on how to maximize your battery performance
so this is something that's more recent that they've updated and it will tell you if you need
to replace it if you do it will give you the cost for that based on whether or not you have apple
care so these are all very helpful things apple has done from optimized battery charging and more
and so i've made this video really to hopefully if you're still watching at this point
to let you know that you really shouldn't have to worry about battery health in fact i hope someday
they change it and it's just something you need to overlook all batteries degrade and there's much
more important things in the world going on and if you need to replace your battery you can pay
the money to do that or replace it yourself if you have the capability and so with all of that
i really just wouldn't worry about battery health at all and of course most people swap their phones
every two to three years and by that time you'll probably need a new battery anyway you get a
new phone and if you need to hand on the phone to maybe someone else you can replace the battery at
that point so typically i tell people don't worry about it just enjoy your phone charge it at night
and use it regularly and enjoy it and use it so don't worry about those things you can definitely
change the way you charge and try to manage it all you want but that really isn't worth your time
it's definitely not worth my time to do that as far as trying to manage it constantly i just put
it on the charger at night i've done that since the beginning and i do that with all my devices so
i've had pretty good success my wife has on all her phones and everything else that she's had
over the years and her battery health is fine as well she doesn't ever look at it so hopefully that
was helpful and if you have any additional insight i'd love to hear from you in the comments below
if you'd like to get your hands on this wallpaper of course i'll link it in the description like
i normally do and if you haven't subscribed already please subscribe and if you enjoyed
the video please give it a like as always thanks for watching this is Aaron i'll see you next time
