Battery usage timer?

Message #1 - Posted 2006/08/17 - brucemx5

Is there a battery usage timer application available that can tell me how long my iBook has been running off the battery?

All the battery monitory utilities I've downloaded only tell me how much estimated time is left on the battery, not how much time I've used so far.

Thanks!

Good Grief! What *can* you do for the hard of thinking?
If you forgot to look at the menu bar clock when you started, you could always ratio up the percentage and time left. e.g 1 hour left and 33% full, you have been running for 2 hours already already.

Pray tell. What use would you make of this information without the optional time travel module?

Our Sleep Monitor application logs the battery and mains power information you are looking for.

Thanks for the suggestion.

I ended up writing a simple program in C that I can run from the terminal It tells me both how long the computer has been asleep and how long it's been awake since the program started. It's based on sample code that was part of Apple's Power Management Development DDK: http://developer.apple.com/sdk/index.html

Hey dude...thanks for such a useful comment. F**k me for thinking a computer can actually make my life easier by doing the computing for me.
And as far as why I want this info? Well, it's the same reason why there's a trip odometer in your car.
