The battery on my iPod fluctuated rapidly, why's that?

so I've been having my iPod touch (3rd gen, 32GB) for about two years, and the problem to my iPod touch is its battery percentage

when I used the original iOS that came with it (3.1.2) I didn't really notice this problem, but since I upgrade it to iOS 5.0.1 in which I can enable the battery percentage, I realized that there's something wrong with the battery percentage, it keeps fluctuating, in one time, it showed 50 percent, and without any use, suddenly it decreased to 40 percent, and several moments later, it gets back to 50 something percent

any idea about what has happened to my iPod touch?

panjiiriawan,

First off I want to say this is a best guess answer on my part but I have seen this on a macbook pro. The battery percentage is estimated and fluctuates with what is running in the back and foreground including the wifi, the backlight for the lcd, the lcd itself etc. It is not uncommon for it to do exactly what you are describing granted that there are always programs running in the background. I wouldn't worry about it. Wear down the battery below 20% and then fully charge the iPod once a month best using a wall charger overnight. Keep an eye on how long it lasts and when you start noticing it having to be charged often without much use it is time to replace the battery. Hope that helps give you peace of mind!
