How can I maximize my battery life?

"Battery life is all about two things: screen and hard drive access. Reduce them and your battery life will increase.

Turn the brightness down. It's tough to get used to a dim screen at first but you will literally add hours to your battery life.

Hard drive access can be reduced by increasing the RAM and managing programs that hit the hard drive a lot. Set your email program to check every hour and your calendar to only sync every hour. Set your backup software (backblaze, carbonite, etc.) to only run when plugged in or at night. Run less programs at startup.

My biggest issue is that I like to install all kinds of fun programs and try them out - but many applications leave daemons running that suck down the battery..."

"well i dont know how to maximize the battery life but i know how to calibrate the mac battery

charge the battery fully wait 2 hours run the MacBook for an example in battery until it goes to sleep ,wait 5 hours, charge it fully again"

Because Lithium batteries don't have the memory problems that Ni-Cad batteries have, we don't have to worry about 'battery memory'. There is one thing that we do need to pay attention to, though. One of the biggest causes of reducing Lithium battery life ( how many months or years the battery is actually useful to you) is leaving the device ( smartphone / laptop etc ) plugged in while the device is "on". Because many of these devices are doing 'work' while they're in asleep and not turned "off", the battery is constantly being charged at the top end of its range because the device is consuming power. This is not good for the Lithium battery. You are best, if possible, to power the device off and then charge it. When you do this the charging process stops when the device is 100% fully charged. Doing this will prolong the life of your lithium battery.
