I've been suspicious that my 4G iPod battery is, well, sucking because the battery meter drops in no time. So today, I tested it out. I started off with a full charge. When I left for work at around 4:10 PM tonight, I set repeat to repeat an album, randomly selected an album, hit play and let it play through while I was at work. I knew that when I got home at 10:30, if my battery was dead, there was a problem. Well, I got home at 10:30, and lo and behold, the battery was dead. When I pressed a button, the iPod wouldn't even turn on. So even if the battery died as I was pulling into the garage, the battery lasted 6 hours and 20 minutes, half of what's advertised. I know lithium batteries dont last forever, but I don't even use my iPod that much at all and it sometimes sits in the dock for weeks at a time. The iPod is less than a year old so its under warranty. The question is though, if I take it into the Apple Store, will they replace the battery or iPod (for free), or give me some BS about how rechargable batteries lose capacity over time and tell me I'm SOL? Thanks.
