Battery discharge problem

[Kamil96500]

I have been observing strange battery behaviour on my laptop for some time.

When it charges to 100% after a few minutes it drops to 94-92%, it used to not do this (since the F.33 update on 1 May it probably started).

I have the impression that windows 11 is misreading the problem, but I have been doing battery calibration and it is better, but I don't know how much more I can do.

I did a battery test in HP UEFI Diagnostics and it showed the battery to be fine.

The interesting thing is that HP diagnostics, and windows 11 misread the battery capacity by a few % probably.

As for the BIOS I have the latest version [F.34] (I think a BIOS update with a security fix is coming out soon, I noticed on AMD's site regarding security vulnerabilities).

Windows 11: 24H2 (latest update as of 10 December).

in version 23H2 I don't know if the problem occurs.

If anyone has had a similar problem and solved it, don't you dare write, I'm thinking of replacing the battery at the end (if the problem doesn't solve itself).

Your laptop comes from the 2019 market year.

If the installed battery is original one, I recommend having it replaced with a new unit

There is a reason that the batteries are only guaranteed for one year.

Thank you for your help.

I also generally set everything to power saving and it extended the life from 1.5 hours to 3 hours.

I am curious if there are any more tips, and I have looked at the battery report and one aspect puzzles me.

On energy consumption.

You can see that the battery is already running low, so will invest in a battery replacement in the near future.

yooo hello did you install f.35 ?

i dunno but i think all the batteries are faculty i think its cuz of not having cmos battery for our laptops and bios is dependent on battery and i think bms is faulty

Yes I have BIOS F.35 installed and no change.

I'll tell you, I wouldn't have fallen for what you stated myself, but I doubt the BIOS will fix anything in the future.
