I will be getting my first mac computer (blackbook + 4gb of ram) on tuesday and I want to prolong the battery life as much as possible. After doing a lot of searching and reading, there seems to be a few different opinions on how to prolong battery life. Mainly: 1.) Use battery whenever possible and only when charge is really low, charge all the way till full (theory: li-ion batteries work better if electrons are moving all the time + less cycles are better) 2.) Use battery whenever possible and charge daily to prevent charge from reaching really low (theory: li-ion batteries work better if electrons are moving all the time + deep charges hurt battery life) 3.) Use battery as less as possible and keep the laptop plugged in as much as you can (theory: less use of batteries = longer battery lifespan) Also, it seems calibrating only helps to keep battery stat applications accurate and doesn't actually help with the battery life. A lot of people have posted screen shots and stats about their batteries with some of them having very impressive numbers like +100 cycles and still +90% health after a year but don't say what they have done to keep their batteries in great condition. Other people have poor battery conditions but don't post anything so it's hard to figure out what to avoid. So I'm asking you, what is your battery health/cycle/age and how do YOU take care of your battery?
