Why my laptop battery capacity different between design capacity and full charge capacity?

[davihaidar154c02d3]

I'm new to this kind of stuff(because I don't kind a have a laptop before) but I'm a little bit confused about the battery problem that I said on the title, and it's only 3-4 day's from I used this laptop(Modern 15-A11SB) when I checked it the design capacity's are at 52,440 mWh and my full charge capacity's are at 49,430 mWh. I'm sorry for my bad English, and I will appreciate it to who's gonna answer or explain it, thank you.

Battery protection mechanisms....
A battery’s charge initiation capacity (%) is usually set between 90%-99%. The actual value will differ by model.

It's really normal.
Usually, the full charge capacity won't be the same as design capacity, even if it's a new laptop.
And full charge capacity will decrease over time according to your habit.
If you don't use battery usually, I suggest you perform battery calibration every 3 months.
