Terrible battery life on the iPod 5G.
Llorean:
Did you wait until the iPod actually shut down from low battery, or did you turn it off after it reached a certain percentage?
Toxikator:
I get great life, I don't know what you guys are doing :P
I take it with me at 8:00 AM and get back at 9:00 PM... it's not on for all of that time but I've never seen the bar below 50%.
You might try turning off the fade-out on pause (do this anyway, it makes it more responsive), load the DB to RAM if you use it, and make sure to LEAVE IT ALONE.
that backlight will kill you. If you just pick your song, play it, and then leave it until you know what you want to listen to next it works great.
EDIT: Also, I don't know how the iPod screen works, but if it's like most, then it uses less energy the darker the screen is. My theme is a modified Blackglass with a black background (except for a black-and-red solar eclipse image). I got rid of essentially all whites to eliminate font reading problems; and I got rid of that highlight bar in favor of the little arrow.
So I have a really REALLY dark, simple skin, which is probably going to use less light and energy when backlit than a lighter-colored theme.

Sure?
I'm thinking "backlight".
Not oled... So if backlight is on you are using "this" much energy per second. It doesn't matter if your lcd is blocking light or not.
I'd argue that, even though it's probably not measurable; running dark images or dark background color rather than none, ie white, would cost you more energy since you have to have your pixels set.

Well, that's just it. It seems to me that the iPod 5G (the video) uses a pixel-panel screen like a laptop... so pixels (and subpixels) are either on or off, not like a backlit LCD. But again, I don't exactly know how the 5G screen works. I use the term "backlight" becuase that's what Rockbox uses in the settings panel, but I think on the screen it's just a "light intensity" or "brightness" fade.

If it's an oled, ok. If not it is backlit.
