Do I need to calibrate my new M1 MacBook Air battery?

[johnkree]

Hello!

I just got my new MacBook this Monday and I was wondering if I should calibrate the battery or does it come calibrated? I usually charge a battery when it hits the 40% mark, so I was wondering if I should empty it the first time till it shuts down?
And should I charge it longer for the first few times?

I read somewhere that I should keep it connected for about 2 hours when it hits 100% of charge?

Having to calibrate batteries was with the older model Macs. You don't need to do that with this Mac.

I hope you enjoy your new M1.

Please don't do that. Avoids fully charged and empty charged for a long period of time.

Why you shouldn’t calibrate the battery in your iPhone, iPad, or iPod

Calibrating the battery in your iPhone, iPad, or iPod sounds like a good idea until you learn more about how lithium-ion batteries work.

That's an interesting article, but the comments below it still offer contrary opinions. Is there truly a DEFINITIVE conclusion on this?

Thank you. Do you think that it's even safe to charge the battery to 100%? Considering that the M1 Doesn't need a lot of power and the device will stay at over 80% for a day with just sporadic uses?

Whether or not you need to, he's talking about only doing it once to calibrate.

Do you think there is a reason to do it when you get charge your first cycles... I'm confused. The article says no, some people claim that they do it...

So why wouldn't you just do it.

There is no need to do it at all. It serves no benefit and can be detrimental (even in a small way) to the battery. Apple has built battery optimization into Big Sur and the M1.

The people you may read doing such online are those who got used to doing it years ago with Macs and iPhones and never stopped. And just because said people continue to advocate an archaic method that serves no purpose, that doesn't mean the repeated admonition has merit.

If you want to waste time calibrating something that doesn't need it, you can do that.

How do you figure that doing it once at setup and maybe once a year is detrimental?

Thank you for the clarification. I see...

If there is no need to do it and it will degrade your battery, whether you do it once or more, why do it?
If it indeed helps Apple would put an article promoting it on their site.
