Switched over from PC this June. The 8-10 hour battery + 30 day stand-by sold me. However, My battery, fully charged has never offered >6 hours of time remaining, and the battery healthis already <93% in a matter of 3 months. I am thoroughly disappointed with my battery life
try these, and see if it improves your battery life.
turn keyboard lighting off or to 1 bar.
turn your screen brightness down to 50%
turn off bluetooth if you're not using it.
turn off infrared remote receiver if you're not using an apple remote.
turn automatic brightness off.
do remember, if you have any apps running in the background, that will also affect the life of your battery.
also have a look at your activity monitor - under all processes - see what's using up 10% and above in your %CPU section. 10% and above will also use up your battery life.
good luck
why is my battery life so poor
