Hello,

as the title says, I started to feel concerned about the battery life of my Macbook (M1 Pro) after exactly a year of usage.

It is usually plugged during the day, and I will need the battery once or twice a week (working on battery for a full day).

Though, it’s not plugged 24/7, only when I’m at work (so not during nights and week-ends for example)

When comparing with a colleague that did almost 200 cycles (something like 191), I was surprised to realize that his laptop also is at 91%, with more than a hundred cycles than mine.

Also, when I’m comparing to my GF macbook air, which is only 50 cycles after 2 years, and knowing that she sometimes doesn’t care much about preventing the battery to reach 0% or whatever, that is still at 100%, I don’t really know what to think…

Am I doing something wrong here ?

Did I literally burn my battery or is the total capacity somehow varies depending on what’s happening with it? (like, is it possible that in a week it came back at, idk, let’s say 93) ?

When I’m reading a bit on apple’s website, everyone says it’s normal, but I don’t understand how 2 people could have this much different results

Thanks

    There are many factors that contribute to battery degradation. Cycles and age are factors (as you’ve already identified) but also heat and differences in manufacturing.

    So, maybe you run more intensive apps than your girlfriend and, because of that, your battery gets warmer. Or maybe she just got a good battery from the factory.

    This is why all of the situations that you’ve described are considered normal.
