Many questions that arise with respect to the iPod battery, such as
how long it will last and if it is replaceable. Despite rumors, it is
possible to replace the battery in the iPod. The following will answer
some of the questions related to the iPod battery.
1. How long can an iPod user expect their iPod battery to
last? The iPod battery is rated to last 500 charging cycles. Depending
on the use of the iPod, the battery should last for over 18 months. In
actuality, the battery is likely last more than two or three years. To
extend the life of the battery many consider it better to recharge a
battery before it is fully discharged. While charging, voltage level
and charge are measured so it is not possible to over charge and damage
How is it possible to tell if the iPod battery is going bad? The
battery in the 3rd generation iPod should last over 8 hours of playtime
and the 4th generation iPod should last over 12 hours of playtime. If
you do not get over 8 hours of playtime this does not necessary mean
your battery is going bad. Depending on iPod use, playtime could be
shorter. Apple considers a bad iPod battery to be one that is incapable
of holding more than 50% of the charge a new battery should hold. If
you are consistently experiencing 4 hours of playtime in the 3rd
generation iPod or 6 hours of playtime in the 4th generation, you might
want to consider replacing your iPod battery.
3. How accurate is the battery meter? The battery meter
is not very accurate. Even if the battery meter lists a low battery,
the iPod could still have several hours of playtime left before it is
dead. Even when the iPod says it is fully charged, the iPod could
should a half charge. After a few minutes of playtime, the battery
meter will show a full charge. The battery meter's intent is to give a
rough estimate of how charged the iPod battery is.
4. How is it possible increase playtime before the
battery dies between charges? Mean time before battery recharging
depends on how the iPod is used. There are several steps to increase
the battery life. These steps will not drastically increase playtime in
an iPod with a bad battery. If you try these steps and still have a
short playtime then chances are high you need to replace your battery.
Do not skip songs - The iPod works by reading multiple
songs into the RAM and then turning off the hard drive since the hard
drive consumes a significant amount of power; the longer the hard drive
stays off the longer the playtime. Playtime is reduced, if the iPod has
to keep the hard drive spinning to refill the RAM. If the iPod is given
a play list to play and is not touched, playtime will be significantly
longer than an iPod that is constantly switching play lists.
Turn off the backlight - The backlight consumes some
power. If you are in a well-lit room, the backlight is unnecessary and
should be turned off. If the light is necessary to read the iPod screen
then the light should be set the shortest time required to read the
Turn off EQ - Turn off the EQ in settings screen. The
iPod uses power to adjust the EQ for each song so by turning it off
Turn down the volume - Turning down the volume will lower the power required for the headphones.
Do not use iPod add-ons such as the iTrip or iTalk - While
these devices extend the use of the iPod they work by consuming power
from the iPod battery. If you must use these devices then you might
want to consider the Belkin iPod Backup Battery Pack that will extend
the playtime for iPod between charges.
Use compressed songs - The iPod contains 32MB of RAM most
of which is used as a buffer for songs. The iPod fills the RAM, and
then turns off the hard drive. If you have compressed songs (MP3, ACC)
opposed to uncompressed songs (wav) more songs will fit in the RAM
allowing for longer playtime before the hard drive must spin up to get
more songs for the RAM.
5. How do you get the iPod battery replaced?
If the warranty period for the iPod is not over (1 year for standard
warranty, 2 years with AppleCare) Apple will replace the bad battery if
the battery hold less than 50% of its original charge.
