Hi everyone Aaron here for ZolloTech and
I wanted to talk about battery health as I get questions about this every single
day the battery health that’s within the battery on the iPhone where it gives
you your maximum capacity and currently this is my XS max it’s at 100% and
people are always asking me what I do to maintain that so well so there’s a
couple things and some people may or may not agree with me but I’ve done quite a
bit of research on this from different websites such as Popular Mechanics and
PC Magazine to things like battery university and other documents from
professors as well so what you’ll find though is when you ask a battery expert
some people say one thing some other people say another thing so I’ll give
you what I do to maintain that battery health number so the first thing you
need to understand is batteries are in a constant state of decay they decrease
size over time so unlike your vehicle’s fuel tank if you have a ten gallon fuel
tank it will always be ten gallons but on an iPhone or a battery that 10
gallons over a year may shrink down to nine gallons and then after two years
could be eight gallons and over time it degrades enough to where it can’t fuel
the power needed from the iPhone so that’s what’s happening with battery
health and what that’s actually measuring its full ability to hold the
original capacity now Apple says that after 300 to 500 cycles you should be
able to get about 80% of your original charge still so a cycle is when you
drain your battery from 100% down to zero and then bring it back up you’ve
cycled the battery now if you’re only draining the battery 20% and bringing it
back up that’s not a full cycle that’s only about 1/5 of a cycle or 20% of a
full cycle so those don’t count as full cycles the math is a little bit fuzzy
depending on who you ask but it’s basically if you drain it down 50%
charge it drain it again 50% now that you’ve got a full cycle now the number
one thing that affects iPhones over time is heat so if you’re an environment
where it’s constantly around 100 degrees Fahrenheit that’s going to be more of a
factor in degrading the battery than charging it so if you’re going to drain
that battery down and charge it that’s okay but if you’re in a hundred degree
heat it’s going to degrade the actual chemical physical ability for that
battery to maintain its charge over time so I
wanted to show you my examples of 100% here on the iPhone X after one year of
use I’ve got 90 percent or 97 percent left
and then on the iPhone 6s plus after a few years of use it’s at 86 percent so
these are all doing really well after that amount of time now this meter is
here to tell you whether or not your battery can maintain its peak
performance over time and supply all the voltage needed if it’s bad it will come
up and tell you that it’s bad so let me show you what I do to maintain it and
this is where it gets a little controversial because some people don’t
like this but in a battery of this size we’re not talking about a battery for a
vehicle like a Tesla this is a battery that’s small and really the best thing
to do I’ve found is charge it overnight now people are gonna say don’t do that
and here’s let me explain that a little bit and there’s this is what a lot of
people say this is the charger I use I use a wireless charger I set it here
overnight and let it charge once it hits 100% Apple actually cuts the voltage
they regulate the voltage coming into the phone they’ll pull back the voltage
and just trickle charge it to keep it at 100% much like you had a battery tender
on a car or recreational vehicle or whatever you’re using same idea so a
trickle charges that keeps it up there and many experts I’d say most of them
that I’ve found say that it’s far better to leave it like that than it is to
actually drain it down to say 70 or 80 percent in charge of backup over and
over and over the other thing I do is while I’m driving throughout the day
this will be plugged in and I’ll be using apple carplay now you don’t have
to use apple carplay you could plug it in while you’re driving that will charge
the battery it’s much better to charge the battery in small increments
throughout the day than it is to let it drain all the way down and charge it
back up so that’s really all I’m doing is I’m
leaving it on a charger overnight it’s not a fast charger and I wouldn’t
recommend using a fast charger regularly the iPad charger is an excellent charger
to use regularly and that’s what I used for years until the wireless charger
that I just showed you here actually came to market so before iPhones had
that ability I use the iPad charger that’s not really a fast charger it’s
just a little bit faster charger a true fast
charger will push a lot more power into this like you see on other Android
phones you can use a MacBook charger to charge this more quickly but it’s still
not on the same level as some of the other phones so I would recommend using
an iPad charger if you want a little quicker charge or the original one
included so that’s why my battery health is so good I know a lot of people are
going to say don’t charge it overnight only charge it to 80% and most people
I’ve heard talk about this or read about have said it’s far too much of a pain to
do that with an iPhone and you don’t need to because the size of the battery
it doesn’t matter anyway if you’re using a car like a Tesla with a huge battery
it’s much better to keep it between 40 and 80 percent over time so that you
maintain it over that length of time but with a phone you’re getting rid of it in
a year or two and then it’s getting refurbished or you’re selling it off and
that person can replace the battery fairly inexpensively but still after
years I’m only down to 86% on the 6s plus so it really just depends on what
you do fully cycling that battery over and over is far worse just plug it in
use it and enjoy it and you’ll maintain that battery health just like I do let
me know what you think though in the comments below if you haven’t subscribed
