You can check the status of your battery by clicking on the battery icon at the bottom of your screen.

Alternatively, you can notice some kind of light next to the power port. The light will change its color once the laptop is fully charged. 

People say it’s advantageous to charge your laptops only up to 80%-85% and charge them only after draining them completely.

But that is not necessarily true in all cases. Gadgets like laptops and mobiles have an inbuilt mechanism to notify you about battery drainage.

You must have noticed these gadgets show fully charged only at 100%. If charging to full was harmful, the manuals would contain relevant instructions.

You don’t have to worry about over-charging but be careful while charging in summer as your laptop may get heated quickly.
