Read about: iPod Battery

Since it was first launched in October of 2001, the iPod has all but dominated the personal consumer electronics market. With its slick design and impressive functionality (all the more impressive considering its small size) the iPod has solved the problem Apple originally saw in digital music players of the day; devices that were either “big and clunky, or small and useless.” While the iPod has featured a number of impressive technological achievements and advances over the years, one of the most impressive aspects of the device is its patented iPod battery.

The iPod battery has seen significant improvements with each generation. While the first generation iPod featured a 10 hour battery life when playing music, the most recent sixth generation iPod features a full four times that amount, featuring a 40 hour battery life when playing audio. Other iPod models have also seen significant increases in their batteries life, such as the iPod mini’s jump from 8 to 18 hours of battery life, the iPod nano’s jump from 14 to 24 hours of battery life, and the iPod Touch’s increase from 22 hours of battery life to a maximum of 36 hours of battery life.

The iPod battery has gone through a couple different methods of charging. The original iPod battery was charged via either a Firewire connection (which also transferred music) or by using a power adapter. Eventually Apple adopted the more standard USB connection for charging iPod batteries.

While iPod batteries are impressive, it’s necessary to periodically order a replacement battery for your device, as any and all lithium-ion batteries burn out over time and lose capacity as they get older. Replacement batteries were not originally designed nor intended to be installed by users, though it was possible. While users were physically able to open their iPod battery case themselves to install a replacement battery, working with their iPod’s internal hardware could sometimes void their warranty. This was especially difficult with some models of iPods, as they featured batteries that were soldered into the device’s hardware, and thus were not easy to replace.

To deal with this battery problem, Apple created an iPod battery replacement program in 2003. Essentially, Apple will replace your battery if it drops below 50% capacity during the first year you own the device (two years if you extend your warranty with the AppleCare Protection Plan). When your iPod battery drops below 50% and is out of warranty, you can order a replacement battery from Apple themselves. Over the years they have designed iPod batteries to be easier to replace and install it yourself, fixing the problem of needing Apple to make the replacement themselves.

In addition, there are a few tips that help you extend your iPod battery life. While iPod batteries are designed to optimally last a certain amount of time, this doesn’t take into account the iPod’s full functionality. After all, features such as backlighting and advanced menu commands take more juice than simply listening to your playlist. Some tips to increase battery life include leaving the “hold” button on when you’re passively using your iPod, disabling the iPod’s equalizer, keeping your iPod from overheating, and creating playlists instead of manually jumping around.
