After suffering from a public relations nightmare when iPod users complained on mass about the relatively short life of their lithium-ion batteries, Apple improved the battery life of its hard disc-based players up to 20 hours on one charge for some models. Still, several tricks will let you extend the life of your iPod battery, both the day they use and for the long hold. Note though while some of the following tips will work on the iPod Nano and Shuffle, which use flash memory, they are intended specifically for hard disc iPod models.
Because much of the power consumed by hard disc iPod’s, not the Nano or Shuffle, spins the disc, press pause when you leave the player unattended. Left playing in default mode, the iPod will run until the battery is drained. You can think you have turned off the iPod when you actually entered standby mode. When you press on the pause play button on the click islet until the screen goes dark, the iPod goes into a pause standby mode, which still uses power. If you press any button, it will immediately turn back on again.
When you put your iPod into standby mode, you should flip the whole switch on the top to make sure you do not accidentally turn it back on and drain battery power when it is in your pocket or bag pack. After being in standby mode for up to 24 hours, depending on the iPod model, your device will eventually enter full sleep, which still uses a miniscule amount of battery power. You can tell that your iPod has been in full sleep mode because it will display the Apple logo when it starts back up again. Either way, it is wise to reach out your iPod every 14 - 28 days at the very least, since the battery will be running down bit-by-bit, even in the full sleep mode.
The backlighting on portable devices eats up battery power faster than a piranha gobbles up a goldfish. To do without the backlight, choose settings, backlight timer: off. Turning off the iPod sound equalizer will also preserve battery life. It takes processing power to transform a Madonna dance track into an acoustic tone poem. To disable the equalizer, select settings, EQ: off.
Rewinding or fast forwarding uses extra energy, but so does changing tracks by the previous next buttons, as the hard drive turns on to find an opener song. Similarly, using the devices’ shuffle or random modes, which require frequent access to the hard disc, would put a bigger dent in your players’ battery life.
The iPod sends tracks to its memory cache so it can seamlessly play them all powering down the hard drive. That is great for tracks that are seven megabytes or smaller, the average length of a single, but Podcast, audio books, and other long files need sustained hard disc access, which can run down your battery. An alternative is to use a lower sound fidelity compression method for these tracks. Compressing files as ac’s. Or mp3’s at a 128kilobits/second means that the cache can hold 25 minutes of danger of this level. And keep in mind that spoken content could be compressed much more heavily than music, so do not hesitate to use lower bit rates for this tracks.
