That's completely normal behavior on android. Noticed that ever since my Moto Droid X. Try running a lot of apps, streaming music and playing a game until your battery goes down a few %. Then close everything, swipe it away from the recent apps list and put it to sleep for like 20 minutes. I forget the actual technical reasons as to why or how it happens, but it's not a bug or anything.
