View Full Version : Best first time Battery Practices?

24th April 2010, 10:07 PM
Hi, with the advertised 10 hour battery on the new 13" MBP, mines arriving Tuesday. I'm just wondering, what should I do to achieve the best battery from the first charge?

I was told to let it charge overnight to 100% and then let it go flat to 0%? Is this true? What should I do for the first 2 days?

You will need to calibrate the battery - go here for instructions: Apple Portables: Calibrating your computer's battery for best performance (http://support.apple.com/kb/HT1490)

Don't be disappointed if you don't get the full 10 hours, it's a "perfect-world" estimate based on a number of factors: What you have turned on/off (wifi, bluetooth, etc), screen brightness, what GPU you use (if you have dual), etc etc. My MBP has an advertised 8hr battery but I usually get around 5hrs with everything on and me using it steadily.
