![]() Apple estimates that these models have a battery life of up to eight hours. The 2003-and-later iPod is smaller than the previous models, so it contains a smaller battery same goes for the iPod Mini. But if you’re like most normal people who turn it on and off, tinker with settings, skip around playlists, and turn on the backlight, eight hours is a more likely average. If you let a 2001 or 2002 iPod play all night, you can get about 12 hours per charge. In short, treat the iPod as you would a pet snake: give it a big meal every few days. In fourteen days (or much sooner), the battery will empty itself completely. What about the iPod’s charge when you’re not using it? Turns out that it quietly sips juice even when it’s turned off. Use the light sparingly for better battery life. That backlight, while illuminating, is also a power drain. But if you’re listening to AIFF tracks you copied straight from the CD without compression (you know who you are), the larger file sizes may overload the cache, and your battery won’t last as long. That’s plenty for songs in the MP3 or AAC formats ( Chapter 4). The iPod’s memory cache works best with song files that are smaller than 9 MB. Pushing the iPod’s buttons to change songs forces the iPod to start its hard drive spinning again, which requires energy. To save power, the iPod lets its hard drive stop spinning as often as possible–by playing upcoming music from a built-in memory chip. Like a laptop, the iPod stores its data on a tiny hard drive, and hard drives can be power hogs. Jumping around the iPod’s music library with the and buttons can also burn down the battery sooner rather than later. Pausing the iPod when you’re not listening to it is a good way to save power, especially if you tend to get distracted and forget that the player is set to repeat songs and playlists over and over. Using the Hold switch ( page 5) can make sure that a sleeping iPod doesn’t get turned on, and therefore run its battery down, by an accidental bump or nudge while in a purse or pocket. (If this happens to you, wait until the iPod warms up, then plug it into its power adapter and reset it by pressing the Menu and Select buttons on all click wheel iPods–or Menu and buttons on older iPods–until the Apple logo appears.) It also may present the Low Battery icon onscreen. An iPod left out in a cold car all night, for example, needs to warm up to room temperature before you play it otherwise, it may have trouble waking up from sleep mode. While the iPod can operate without incident in temperatures between 50 and 95 degrees Fahrenheit, the iPod (like most people) works best at room temperature–around 68° F. For example, as better power management is a perpetual goal, the company recommends always having the latest version of the iPod software installed. Someone inclined to settle into a long playlist and let the iPod go without interruption will enjoy more time between electricity refills than an iPodder who constantly jumps around to different songs and fiddles with controls.Īpple has several recommendations, both environmental and behavioral, for getting the most out of the battery. POWER USERS’ CLINICMaximizing Your Battery’s Potentialīattery life varies. The iPod will also warn you not to disconnect it if you’ve set it up to work as an external hard drive, but we’ll get to that business in Chapter 12. It hits the 80-percent powered mark after about three hours of charge time.ĭuring the charging process, you may see either the “Do Not Disconnect” message (if the iPod is also sucking down music from your computer), the “OK to Disconnect” message (if it’s done with that), or the main menu for a few minutes before the charging battery graphic takes over (if it’s a 2003-or-later model). The iPod Photo, however, takes about five hours to fully charge. If you just can’t wait to unplug it and go racing out to show your friends, you can begin to use it after a couple hours. Note, however, that it gets about 80 percent charged after 2 hours (Minis only take about an hour to get the 80-percent power rush). ![]() It takes about four hours to fully charge your iPod. For USB 2.0, you need a powered jack like those on the back of the computer, or on a powered USB hub-not, for example, the unpowered jack at the end of a keyboard.) The battery charges as long as the computer is on and not in Sleep mode. (For FireWire, “powered” usually means the fatter 6-pin FireWire connector, not the little 4-pin connectors found on many Windows machines. If your Mac or PC has powered FireWire or USB 2.0 jacks, you can charge up the iPod just by plugging it into your computer.
