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
