thanks chealion, just been getting kinda nervous with all this batter talk and ipods going around. Mine is always plugged into my car deck, or my home stereo anyways so I really never need it unplugged.
One thing I've noticed with my G3 iPod is that the battery indicator is usually very inaccurate, especially upon switching it on after a few days. Sometimes it registers empty but a few minutes later is at 25%. Temperature also has an effect on the reported battery charge. I also think recharging over a firewire connection to a computer is a bit flakey. However, if I eject the iPod (using the iTunes button) but keep the ipod connected, then charging seems much quicker.
My iPod is about 9 months old and the battery performance is about 90% of what it was new. No complaints and the iPod battery FAQ that Chealion pointed to has lots of useful information (as well as a dig at the Neistat bros).
I've owned two iPods over the past couple of years and here's what I've learned about maximizing battery life:
- keep your MP3 files below 9 megs per track (not always easy when your MP3s include behemoths like Jethro Tull's "Thick as a Brick," and Godspeed You Black Emperor's "Rockets fall on rocket falls.") Big files force the iPod to spin the unit's HD more often and that puts a big drain on the juice. The AAC format is especially useful in squishing down the filesize of long tracks without compromising audio quality (well, not by much);
- whenever possible, try using the wall plug to conduct your recharges (puts far less wear on the battery and the HD because it's not being synced while charging);
- try to keep your syncs to a minimum (draws a lot of power);
- say bye-bye to the backlight;
- disable the Equalizer (and make sure that this is also done to each individual MP3 in iTunes);
- don't use the alarm...ever;
- avoid at all cost leaving your iPod in a cold car...cool temperatures will drain your battery in no time flat. And cold temperatures can damage the HD;
- track shuffling and repeatedly hitting the back and forth buttons are also significant factors behind accelerated battery drainage...same reason as above: the more often your HD spins, the faster your juice will be depleted;
- use the lock switch to ensure that the iPod doesn't accidentally get started up when it's in its cozy Marware case.
My 40gig is only a month or so old and it exhibits the same erratic battery level readings. Even though it says charged, when you play it the level only reads 25%. Only after a song or two does the reading shoot up to full.
