Your iPhone 3G/3GS Battery
Increase Your Phone's Battery Life Back
Opening up your iPhone and
replacing its battery is something best not tried at home.
You need special tools and
a very delicate touch to do this, and most people would
prefer not to risk the health of their phone accordingly.
Use our service and have it
done for you.
Subtly, slowly, and inexorably,
the life of the rechargeable battery in your iPhone gets shorter
every time you recharge it.
But with only a minute or so of
battery life lost each time you recharge, it takes a long time
for this to become noticeable.
Then, one day, you realize you
didn't formerly need to recharge your phone so often and
you ask yourself 'Didn't my phone's battery last longer than
Yes, it did. And although
the phone's battery can't be replaced at home yourself, we offer
a convenient and lower cost alternatives to mailing it in to Apple for a
This article describes a
service for replacing the built-in battery in an iPhone 3G or
3GS. It does not apply to an original iPhone or a new
Depending on how much you use
your iPhone, sooner or later its battery life becomes sufficiently
reduced as to be inconvenient and justify replacing. You
can't do this yourself without special tools and skills.
Apple will swap your entire
phone for a comparable phone with a new battery in it, but this
means you lose all your data and settings, and may get a
replacement used phone in poorer general condition. If your
phone was unlocked, of course the phone they send back to you will
be locked, requiring you to unlock it a second time. Apple

We charge $50 + $2.50 shipping
(and tax but only for WA residents), and replace the battery in
your own phone and return your own phone back to you, so if it was
unlocked before, it remains unlocked, and the data and settings
are also preserved.

The Finite Life of any
Apple iPhones use a high
quality Lithium Ion type rechargeable battery, but like all
rechargeable batteries, the amount of charge it can store slowly
diminishes over time, and with each recharge.
You can maximize the life of a
Li-ion battery by keeping it cool rather than hot, and by
recharging it not all the way from zero to 100% on a fast charger,
but instead from perhaps 20% or so and back up to 90% or so, on a
But however you treat your
battery, it simply wears out over time. The good news is
that it seldom will suddenly fail and suddenly hold no charge at
all - it is more common for the battery to simply hold less and
less charge each time it is recharged.
A general rule of thumb is
that most people consider their battery should be replaced after
about 500 recharges. If you are recharging your battery
every other day, this would represent about three years between
when you first bought your phone and when you should replace its
battery; if you charge it more frequently, then obviously you'll
need to replace the battery sooner.
When Should You Replace your
That is a bit like asking 'how
high is up'.
It is easy to answer that
question with a car battery. One day, a cell will short out,
and it will no longer start your car. That is a more or less
black and white event with no possibility of mistake (although it
is possible also to replace a car battery when it simply no longer
does a good job of providing a high current flow without a great
It is also easy to know when
to replace the batteries in a flashlight - when the light glows
dim orange/yellow rather than bright white.
But with a rechargeable cell
phone battery, the issue is not so clear-cut. We suggest the
appropriate approach is simply to consider when the battery life
is appreciably shorter than it was originally, and/or when the
diminished battery life and need to charge more regularly is no
Generally, a good rule of
thumb is that if you find you are needing to recharge the phone
more than once a day, then you should replace it.
Note also that 'needing to
recharge' does not mean 'runs out of power and stops working'.
So as to be able to handle an emergency event, you always want
your phone to be able to provide you with
at least 30 minutes of talk time
(and preferably more like an hour) - you've probably had a
problem in the past such as maybe a car breakdown where you end up
stuck somewhere away from other phones and spend ages on hold and
talking to people.
You should consider a 20%
battery level as the absolute minimum you should ever let your
phone get to.
The other consideration - when
the battery life is noticeably shorter than it originally was - is
harder to quantify, because the battery life reduces so gradually
that we sort of unconsciously adjust our expectations to match its
Our Replacement Battery Service
We're not as big as Apple, so
we have to provide a better service and a better value to win your
We think we've done exactly
that. Please read on.
First, the big problem, as we
see it, with the Apple service is that they don't send your phone
back to you. So as to provide a quick turnaround, when Apple
gets your phone back, they quickly check it then put it in the pile of phones needing
replacement batteries then forget about it. They then take a
phone out of the other pile of phones - those that have had their
batteries replaced - and send it back to you.
If your phone doesn't meet
their minimum standards in terms of appearance, scratches, etc,
they'll refuse to do anything with it and simply send it back
to you. If they detect that your phone has been
unlocked, they'll probably again refuse to help and send it back
But what if your phone has
been well looked after, and little used? You risk getting an
older more beat up phone. It is a bit like services that
swap barbeque propane tanks. Sometimes you get a good
tank in exchange, and sometimes you get a bad one. It
doesn't matter too much with propane tanks, but it sure
is a problem with your iPhone.
We solve this problem by
sending your own phone back to you.
As for cost, Apple charges you
$79 plus $6.95 shipping. We charge $50 and $2.50 for
shipping (UPS first class mail). We're not sure how fast
Apple's turnaround time is (but it is probably very good) - we
offer a 24 hour turnaround and sometimes get it done same day (but
can't promise that).
What to Do if You Can't Be
Without Your Phone
If you can't be without your
phone, we have a couple of suggestions for you.
The first is - do you have a
spare phone lying around? If you do, simply take the SIM out
of the iPhone and put it in your spare phone, and use that for the
short time your phone is away.
The second is, if you don't
have a spare phone, consider getting a 'throwaway' phone - a
prepaid phone with T-Mobile or AT&T service - and then again put
your iPhone's SIM in that while the iPhone is away. (If the
throwaway phone is from T-Mobile you'll probably need us to first
unlock it so it will work with the AT&T SIM).
Throwaway phones can be
purchased at Target or Walmart for something under $50; sometimes
for as little as $30.
The third is to courier the
phone to us and enclose a courier return label so we can courier
the phone back to you. This will greatly speed up the
process of getting the phone to us in WA state and then back to
Bonus - iPhone Unlock Too
If your iPhone is currently
locked, so it only works with AT&T SIMs, you might want to
consider having us unlock it to work with other GSM wireless
companies too. You can read
more about our unlocking service in general.
Normally we send you the
software and instructions to do this yourself, and there's no
reason why you couldn't. But being as how we'll have your
phone with us anyway, we'd be pleased to do this process for you
at no extra charge (over and above our regular $25 unlocking fee).
