How can I re-calibrate MacBook Pro 14" M4 (macOS 15.2) battery

Oh yes, I bought a macbook m1 pro in November, and this week I had the same problem.

I do not know what to do, yesterday it turned off by 19%, today by 28%.

There is little information on the Internet, I do not know how to do the right thing.

You misunderstood me.

Everything you've written is super obvious.

The only thing is, I don't use power-consuming apps on my MacBook, and I know how the system works.

I didn't have any problems for 2 months, and then suddenly it appeared, but nothing changed in the work scenario, as I didn't use power-consuming applications, and I don't use them now.

You misunderstood me, I don't need to always connect my MacBook to the network, there is a problem that it turns off at 20 percent without warning, that's the whole problem, but not the power consumption, and that's what you described.

<< What do you mean by "always"? >>

"In general, you should ALWAYS connect a power source when it is possible to do so, and only run on batteries (which could be somewhat slower) when no power sources are at hand. Your Mac maintains its battery charge levels under program control, and will NEVER over-charge. "

So when you arrive at a new location, you look around and find a power outlet. You sit closer to it. You plug in your power adapter.

When you put your computer down for the night, you make certain that the power adapter is connected.

If the cord is too short, Apple sells an AC 'extension cord' for your power adapter for about US$20.

Your battery will have a longer lifetime if you don't run it down so low.

Thanks for the information, but I don't see how this is connected to wrong estimated charge displayed on macOS?

The fullness ESTIMATE is sometimes made MUCH worse by tiny internal weaknesses in the individual cells that make up a Mac battery. Suppose one or more cells are getting weak. When the charge level of the group approaches some threshold, say, 20 percent, the total output of the battery could collapse suddenly if ALL the component cells can not carry their part of the load.

The Estimate will not change immediately. But your behavior must change, or it will catch you again and again and again.

if you keep your MacBook at a higher change levels in general, you will rarely care when it says the charge level is low, and exactly how low.

Ahahahah, that's exactly what I want to see on the forum with a solution to the $2000 laptop problem.

Very funny, you made my day.

It's the same thing if I told you: my pants are falling off, and you would advise me to close my eyes to it and not pay attention.

Super obvious, it shouldn't work that way, especially on a laptop for $2000

I agree, I usually charge when I see 19%

But a couple of times, I was "working hard", and I didn't notice how the charge level dropped to 1-5%, and everything was fine, it didn't turn off.
