Battery health after 3 monts

[sangui2]

I using my MBP 2018 since end of July.
It is rather normal usage - some work on battery, some on charging.

At this moment I have 26 cycles, but this is how it looks in battery monitor:


Why I can see 100% if there is only 6881/7200 mAh charged?
Also it is possible that in only 3 months battery Original Max drop down from 7336 to 7200 mAh?

Sorry for strange questions but this is my first Mac and I want to be sure that everything is fine.

Pretty typical, a) most OS's show 100% for the first 5% or so of battery charge, because people in general would be 'unhappy' it only showed 100% for a few seconds when they start using device.
b) a few percent drop during first months is very usual, it's just how batteries are. Mines already lower than that and I've only had it from september. ( 7164 max )

Thank you for explanation.
Do you have MBP 2018?
Well, right now I have 6873/7200 it is still difference.
Why this pointer does not go upper?

It's not charging at this moment to help preserve the battery. It's not good to contininually keep battery on charge, so the battery management lets it drop a bit before it will start charging again. If you unplug/replug power cable it will probably start the charge cycle again, but I wouldn't do this unless you want it to be truly at 100% for some reason.

It make sense.
My only worry is the 2% drop capacity in only 3 months.
You have similar capacity, yes?
Can you check in some battery health app?
Anyway, how many cycles you have right now?

About the same, and it really is very normal. It's a subject that comes up frequently, battery degredation is not linear, the fact it's lost 2% in 3 months does not in any way imply it will have lost 8% in 12.

Measuring battery capacity in itself is an imperfect science, the figure is more the systems attempt to track battery charge/discharge rather than an exact true value, too.

Only way to know true battery capacity is to run a complete discharge/recharge cycle whilst measuring charge/discharge power usage, really, everything else is an estimate.
