I just got tap tap 2 from the app store, and after playing only 2 songs in it, my battery life dropped about 8% (I am using a jailbroken ipod with the numeric battery enabled, and it dropped from about 87% to 79%). Now I know the numeric battery counter will be a little off, so I'll just say it probably actually only dropped anywhere from 5-8%. But still, 2 songs is only around 6 minutes of gameplay, and taking down over 5% is a little too much isn't it?? I also read on a youtube comment where someone said he played tap tap 2 for 30 minutes and it took down about half of his ipod's battery. Do all games take this much of your battery away??
