Windows 10: Msi laptop battery capacity sudden decrease

I bought my msi laptop about a year and a half ago, these days i noticed a sudden battery drain, if not on power saving it shows an estimated time of 15m or so, with nothing running in the background, i take a good care of my laptop and I'm worried cuz battery report came back kinda bad, so is it time for battery change or is there's something i can do to reduce this fast drain. Ps: on power saving mode it lasts about an hour and a half barely.

Battery full charge capacity decreased?





As you can probably see from the above image, my battery's full charge capacity has been decreased. Even though I just bought this laptop like 3 months ago, the laptops full charge capacity has been decreased by a huge amount like 5000mWh. I don't know what is causing this I have three questions...

i) What causes a battery to lose its Full Charge Capacity?

ii) Can a full charge capacity be increased (reversed) by using it the right way again?

iii) How can I save my battery from losing it's full charge capacity? Will using it plugged into the charger help it not get decreased?

 

Battery full charge capacity is decreasing

Hello there,

There is already a question in Microsoft forum but I can't reply it because it's locked:

Redirecting

My issue is very similiar, the only difference is that my laptop is Asus notebook A541UJ.

Here is the thing: I already bought 2 new batteries and within 5-6months of usage, the capacity goes from 28 000 kWh to like 6 000 kWh, so, my guess now is that the Windows Operating System is not dealing very well with the batteries. One of my latest battery report shows that I'm reaching 431% of battery capacity. Probably because I changed the battery and it considers the "100% full charge capacity" as 7 000 kWh and not the correct 28 000kWh (of the new battery).

Thank you for the attention
