Battery charge capacity reduced quicker than it should be

Hi,

Looking for some advice to improve battery performance and extend battery life.

Two weeks ago i bought a new ASUS F555LA-AB31 laptop. I removed Windows 10 and installed Ubuntu on it. For the first roughly 10 charge cycles, the batter charged to 100% capacity with no issue. Since then, the battery has been through about 5 charge cycles, not charging to its maximum capacity but only to 97%. Asus specifies that the battery is good for 500+ charge cycles.

I just fund out that Linux has worse battery management capability than Windows. I'm not sure to what extent that is true but if it is, I would like to do everything possible to optimize the lifespan and charge capacity of my new battery.

Please help!
