@NidalNh,

Welcome to our HP User Forum!

Summarizing: I see nothing wrong with your battery.

Normal deviations you would expect to see from one cycle to the next. No downward trend.  All well within battery specs.

Kind Regards,

I really thank you for your effort

but my question was about the design capacity isn't supposed to be a fixed value because mine keeps changing over time

and please excuse my english

@NidalNh,

My friend, there is a difference between manufacturer battery design capacity vs actual battery capacity, which is what the numbers you see show.  These numbers will change, and over time the actual battery capacity will trend down.
