(MacBook Air M1) Diferences between Better battery 2 and OS battery charge indicator

[Javi74]

Hi!
Again, sorry for my poor English. Not my mother tongue.
I'm quite obsessed about the battery, and I installed Better Battery 2.
I've realized that the charge that it says doesn't mach the one that the OS says. You can see the image

Is it usual? Does anybody know why?

Again, thank you all. For a newbie in this OS, this kind of forums are really helpful.

The OS indicator always displays a few percent above the actual charge level. This is normal and has always been like that.

It’s probably because Apple has a battery life curve that they use that isn’t just a linear representation of current charge divided by full charge.

As an aside, your English is great!

Better Battery 2 will give you the accurate status.

I have found that the OS rounds up and will usually be .5 - 1% off at times, compared to said app.
