Why did the Full Charge Capacity of the battery drop sharply?

Question

laptops

The laptop is 1.5 years old. For a year of operation, full charge capacity has decreased from 51t to 48t.

Over the past six months, for some reason, this figure has already fallen by 11t

. And after checking again after 2 days, I saw that it fell by a thousand again.


I would like to know what can cause this a sharp drop and are there any alternatives to changing the battery?

Answer 1

The battery is a consumable item.
It just ages and loses its capacity.
Try to charge to 100% and discharge to 0%, then look at the indicators. Maybe the controller is dumb. If it stays the same value - reconcile.
