these days we use our phones for way
more than just making phone calls and
all that use means your iPhone's battery
is gonna get some serious wear and tear
the batteries and iPhones and all cell
phones are consumable products in fact
the average iPhone battery retains only
80 percent of its original capacity
after 500 cycles to put that into
perspective if you charge your iPhone
battery every night for a year and a
half the battery meter would still read
a hundred percent but your battery life
would only last 80% as long as it did
when you first got it you know when your
car needs a new battery because it
doesn't start out but how do you know
when it's time to replace the battery in
your phone here are six signs that it
may be time to swap out your iPhone's
battery number one your iPhone often
turns itself off if your iPhone suddenly
shuts itself down when the battery is at
50% or so the calibration might be off
to calibrate your iPhone
follow these steps step 1 use your
iPhone until it shuts itself down due to
low battery step 2 plug your iPhone into
a reliable charger and let it charge
uninterrupted to a hundred percent
step 3 once it's charged perform a soft
reset by holding your sleep/wake button
and your home button down until the
Apple logo shows up if you're on an
iPhone 10 you'll be holding down the
sleep/wake button and the volume button
if that didn't solve the problem the
battery may be the culprit and you
should replace it what's happening is
that lithium-ion batteries have a
voltage range in which they operate
safely and this is enforced by the power
circuitry as lithium ions age their
internal resistance grows so when the
phone does something processor-intensive
it draws significant current pass this
current through the increased battery
resistance and you get added heat
generation and substantial voltage drop
number two your phone feels sluggish if
you're using an iPhone 6 or later you
may be subject to CPU throttling if
you're running iOS 11.3 or later you can
check your battery health by going to
the Settings app select the battery
option in the list and then select
battery health under peak performance
capability if you see a warning that
your battery health is significantly
degraded it's time for a replacement
number three is an obvious one your
iPhone has terrible battery life this is
especially true with iPhone 5s or
earlier
earlier iPhones aren't affected by cpu
throttling so the only sign of a dying
battery will be shortened usage times
swap out the battery and you'll be
boosting the battery life number for it
your iPhone works but only when it's
plugged in you might have thought your
phone was completely dead but when you
plug it in it magically comes back to
life unfortunately no matter how long
you leave it plugged in as soon as you
disconnect the power cord it shuts right
down sign number five your phone gets
hot like really really hot it's normal
for your iPhone to generate heat during
heavy use and charging but if you notice
that your phone's becoming too hot to
touch it might be time for a new battery
and lastly your batteries got bloat this
can be a tricky one to spot but you'll
know it when you see it batteries can
sometimes swell due to a failure of the
smart circuitry or physical damage like
getting bet in your back pocket you may
start to notice some unexplained bowing
or case separation along the sides of
your phone a hazy white screen or even
some squishiness when pressing down on
your screen in some more extreme cases
you might even see some unexplained
screen cracking no matter how you
discover it a swollen battery is
something that requires immediate
attention the battery should be treated
and disposed of properly as soon as
possible so if you're experiencing any
of these battery problems head on over
to ifixit.com and pick up an iphone
battery fix kit it's a super easy repair
that you can do yourself in under an
hour I'll see you next time
