I'm curious as to what my cpu is running at when I'm playing music and my screen is off. When I'm using my phone I have it set to 1ghz and when in standby(screen off) I have it at 250mhz. Now when I'm playing music from pandora, lastfm, or just regular music player, is my phone running at 1ghz or 250mhz. The screen is off during playing music. This could have a good effect on battery life if its running at 1ghz that whole time. Anyone know the answer to this?
