View Full Version : [ubuntu] How accuate is Ubuntu's battery meter?

August 18th, 2009, 12:05 AM
The Gnome battery meter says my brand new laptop battery is only charging to 75% of what it should be (meaning the battery's health, or capacity, is 25% diminished from what a new one should be). So I'm wondering just how the meter gets that figure and if its accurate. I'd hate to think my new battery is already 25% shot. Also, can someone recommend a reliable meter for windows (for comparison)? Thanks for any help.

HP says that you need to do a complete drain-charge cycle every three months or so to keep batteries healthy. You do this by disabling all actions on low battery charge and let the computer poweroff when battery is drained. And then you charge it until full charge with laptop powered off.

Also, I read somewhere in the forums, that you need to 'let Ubuntu know' your battery life by letting it drain once, and then fully charging.

I'll give that a try, thanks!
