Optimal Battery Handling

I believe the only thing that is recommended is a 'calibration' which is done every month or so by allowing the battery to drain completely before plugging it back in.

This is more of a calibration for the internal battery gauge than for battery life though. As I understand it, the battery and computer are not picky about how you use them. Just use the computer as you need to and you will be fine.

It's not like the olden days where batteries had a 'memory' and would not fully recharge. Current battery technology essentially eliminates this problem.

 

Use it however you want it. Letting overblown worries about a few percentage points in battery life is, in my humble opinion, quite stupid.

Plus if you leave the cable plugged in all the time, why even worry about the battery?

 

While mstrze's post is largely true, it can be hampering to your battery life to keep it plugged in. If you do unplug your computer, allow it to drop before 40 before recharging. This isn't because of "memory," but because it enhances the flow of ions throughout your battery.

In addition, do calibrate once a month as well.

 

My wife has had her MB since late 2008 and probably leaves it plugged in 95% of the time. We don't really have any issues...although I have told her that she might want to leave it unplugged once a month for the calibration at least.

miles01110 is absolutely right...just use it and don't worry about!

Calibrate it like apple suggests. You can charge/drain as you like. There is no sweetspot percentage to charge it at to get good battery life. Best thing you can do for these batteries is keep them working, but do not drain them fully (except when calibrating them) and you're fine.

 

So you warn that one shouldn't drain them fully, yet you agree with Apple that one should drain them fully (to calibrate) once a month.
