How long is the maximum battery life of every iPod model?

For your convenience, EveryiPod.com lists the maximum battery life of every iPod, as estimated by Apple, on the main iPod specs page along with other basic information.

How many charges should I expect to get out of the iPod?

Apple states that "rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced. Battery life and number of charge cycles vary by use and settings. As with other rechargeable batteries, you may eventually need to replace your battery".

The excellent iPod Battery FAQ website, citing BatteryUniversity.com, states that the Lithium Ion battery used in the full-sized iPod, iPod mini, and iPod nano models should provide 300 to 500 charge cycles.

Why won't my iPod battery charge completely? Why does my iPod run out of power so quickly?

If your iPod displays icons that do not make sense for the situation -- such as a charging icon when the iPod is not plugged in to a computer or wall outlet -- or is otherwise behaving oddly, you may be able to correct this situation by resetting the iPod. Try the Apple recommended "five R's" and see if this solves the problem.

If this doesn't solve the problem -- particularly if the iPod is a couple of years old -- in all likelihood the battery has reached the end of its useful life and needs to be replaced.

Site sponsors Other World Computing and Mission Repair offer an iPod battery replacement service.

How can I conserve battery life?

The Apple Support Site provides "Tips and tricks to get the most out of your iPod's battery". This document offers some useful information including updating to the latest version of the iPod software, setting the Hold switch to the Hold position when the iPod is not in use, and keeping the iPod at room temperature, among others.

Generally, keeping the iPod from becoming completely discharged also may prolong the life of the battery. BatteryUniversity.com also provides some additional tips on how to prolong lithium-based batteries.

How do I replace the battery in the iPod shuffle models?

If it is out of warranty, Apple will replace the battery in your iPod shuffle at a cost of US$49 plus US$6.95 shipping.

Unfortunately, since new iPod shuffle models start at US$49 it makes little sense to have the battery replaced by Apple. Since the designs are difficult to open without damage, the batteries are soldered, and there is little demand, third parties tend to not offer repair services or self-installation options either.

Ultimately, when the battery in the iPod shuffle dies, Apple has designed the device to be discarded. It's definitely the least "green" iPod option.
