HP ProBook 45 G6 battery design capacity is changing

[VedranH]

So I have bought HP few weeks ago, and today I run regular Windows 10 battery test and found some strange data.

 As You can see design battery capacity is going up and down, depending on max charge capacity. I have alredy run HP Support A and HP Diagnostics, but all of the returned postive feedback about battery. I tried to reinstall Microsoft ACPI- Compliant driver (as some of the answers on this forum proposed), but none of them changed this issues. Also original battery capacity should be 45Wh, and as Yaou can see this is obviously not a case here. Is this normal, to have about 94% max capacity of battery on first use, and to see design capacity going up and down? Or should I do something about that, like replacement or something like that?

NOTE: This laptop is used for regular stuf, including programming, so some heavy actions like gaming did not cause this issue. Also if that is important laptop was bought in Croatia, European Union.

These variations are well within normal testing error and just indicate your battery, being pretty new, is still working at 100% design capacity. 45w is going to be approximate and the numbers here are perfectly normal. Enjoy.
