MBA battery doesn't require calibrating?

[petrucci666]

I read on the Apple Support page that 'these batteries are pre-calibrated' and do not require the same calibration procedures that notebooks with removable batteries do.


What do you guys have to say about that?

That just means they did it at the factory. It will still benefit from calibration on occasion just as the rest of the models do.

One less calibration for you to do. I don't see what the point of this thread is, since you will likely still need to calibrate at some point if you use the battery at all.

How many 'ordinary' people owning a Mac would think or know how to calibrate their battery...

I know two friends who won't have a clue about this process.

So, I believe it's not necessary. And yes Apple even say so. Pretty sure that body of text on their website means this. They wouldn't mince their words and it's a clear indication there's no need for it.

Think it's just a bit of OCD again tbh.

This should answer most, if not all, of your battery questions:

Yeah, apparently you don't need to calibrate... ever.

I'm in this boat as well and am curious as to people's motivations; not to be judgmental or anything, I'm just genuinely curious.

My approach to laptop batteries is I just use the laptop. I don't leave it plugged in for weeks at a time; I run the battery down every so often on a schedule governed by my thinking "gee, I haven't run the battery low for a while"

Calibration has nothing to do with battery health, which is the #1 reason people seem to think they need to cycle their battery. Calibration references the battery reading in the menu bar to the actual power level remaining, so instead of entering sleep at 10% remaining it will enter sleep at 0% remaining.

Calibration isn't that important anyway. The only thing it does is making the battery display accurate, it doesn't affect how long the battery lasts. If your battery is fully charged, it will last exactly the same time, whether it is calibrated or not. If it is calibrated, the display will go from 100% when you just unplug the charger to 0% where the MacBook turns itself off. If it is not calibrated, it may display different numbers. The warning when the battery is down to 10% may come a bit earlier or later. But the battery will last exactly the same time.

Interesting. Thanks for the clarification.
