Anyone else receive multiple battery alerts every time your battery gets around 20%? Not sure if I've got a funky battery, or if it's commonplace. My battery life doesn't seem to be horrible, so it's more of an annoyance than a problem.

^Yes its normal, mine does the same. Mine also starts acting weird (sluggish, closes apps, etc once it gets below 20%) But so does my iPhone and iPad.

Yes with my iPod touch 4g. And I don't even get a 10 percent warning. Using voiceover, the battery percentage when I tap the icon on the status bar is different from the one when I tap on the charging device icon.

MIGHT be able to explain some of the weird behavior.
Apple, for reasons known only to apple actually limited the accuracy of the battery level readings. If you get certain apps through cydia (highest accuracy) or even the app store (better, but not great), you can get a better reading than the OS will provide.

I had this weird thing happen. I had a app from cydia that monitored the battery, and it used a high acc setting. Because there were 2 different "battery formulas" being used at once, I think it confused the device, cause right after I installed the app, the multiple battery messages started.

Cydia is instaled into the system file so it is right in the middle of the alerts, So your probly right that it did get confused.

Never seen such a problem on iPhone 3gs, 4, iPad, iPad 2.

Maybe contact Apple for support?

I've always had this happen on my previous iPod touch(es). I'm not sure why, but I believe that the software is just estimating the remaining battery in a far less accurate way than on the iPhone. I'd notice that it would alert me to 20% or 10% remaining battery, and then I would notice the battery indicator seeming to rise slightly before I received another alert.

It always happens to me. I think it's because whenever I reach 20%, it goes back up to 22-23% if I don't use it for a minute and when I use it again it goes back down to 20%. It gets very annoying.
