I heard calibrating the battery is recommended every other month or at least once/twice per year.

If I’m not mistaken it was recommended by Apple to adjust battery readings in MacBooks and other devices.

That's why I do it with my new devices.

It just gets you going on the right track.

People have their own little habits, and this tends to be one of mine.

My last rMBP had 3000+ cycles on it. I always ran and it zero and full charged it. It's simply wise to keep the electrons moving.

It did drop to about 63% capacity after 3000+ cycle and 2800+ days in age.

I used to always run my devices down to zero (to the point where they turn themselves off) but I don't do it ow, as I find it inconvenient.

Eg, I'm currently using this MBP right now, just to get it to power down so that I can fully charge it.

By the way, how long does your new MBA take to charge?

From 10%, 2h28m with the 30W charger.

Seem to get 10h hard usage out of a charge, 8h very hard usage (8h of Zoom over WiFi essentially) and 14h light usage (video over WiFi).

So running it to zero is a long task, literally.

Battery calibration is a myth. At least, it may as well be these days. It’s a relic of recommendations for older, nickel-based batteries. But the battery on your iPhone or iPad uses lithium-ion, and calibrating it is not a good idea.


When we talk about calibrating a battery, we mean charging it all the way to 100% then draining it down to zero. The idea is that doing this teaches your iPhone, iPad, or iPod how much power the battery can hold, allowing your device to make the most of it.
There was a time when Apple recommended calibrating your device’s battery every month. They don’t anymore.

I have an M1 MacBook Pro (8 GB / 256 GB). I timed how long it took to charge from 10% to 100% earlier today: 2 hours, 5 minutes.

Good to know. Means a 45W charger would take close to 3h to fully charge.

The MBA only comes with a 30W charger.

2 hours is great!

We didn't even unpackage the OEM charger/cable that came with our MBA, using an Aukey 65w PD charger (and their 6.6ft 60w spec'ed USB-C cable), I'll have to time it with that charger from < 5%, but holy hell, it was fast.
