Setting "Maximize battery health" not working (with screenshots)

[lukbnda]

Hi all. The power setting "Maximize battery health" is not working for me. I am familiar with this HP support document (https://support.hp.com/us-en/document/ish_4449597-3519507-16) and I know, that even with the setting "Maximize battery health" turned on, the battery indicator will show 100% and no heart icon will appear.

However, if I run a battery check in HP Support Assistant the stats show that the battery has been charged to its Full Charge Capacity (which is on my notebook down to 73% after two years - see attached screenshot). This behavior doesn't change if I set the power management to any of the available settings in the BIOS (latest version), in HP PowerManager or in MyHP. The battery always charges to its full available capacity.

Any ideas how to resolve this? My notebook is  plugged in most of the time and it just doesn't make any sense to have it charged to the max. I want to be able to change the setting when I need it, e.g. before traveling. Any help is highly appreciated.

Hi @lukbnda 

if you observe, when it is charged to 100%, and the next day you use the device you will see that the charging light is off and maybe the battery is at 99% or less, it will only charge again when it is below 95% and the charging light comes on.

Hi @resistencia and thanks for your replay.

Unfortunately I do not understand what this has to do with the problem I stated. The behavior you're describing happens, when the power setting is running in "Optimize battery performance" mode.

In my understanding the setting "Maximize battery health" is supposed to protect the battery and not to charge to 100%. I understand that in any case, the battery icon in the system tray will show 100%. Yet despite my power setting "maximize health", the battery is charged actually to 100% (to the full possible charge capacity as can be seen in my screenshot). Always.

Furthermore, if the mode ""Maximize battery health" was working and the battery was actually charged only to the described 80% (but showing 100%), should the notebook not start to charge the battery when I change the power mode?

This is what I would expect: "Maximize battery health" mode is on, the battery is protected and charged only to 80% (although 100% is shown in the tray). I turn "Maximize battery health" mode off because I will be on a plane or something and need my full capacity - at this point I would expect to see, that the battery is being charged to 100%, because it was only charged to 80% to protect it. But this does not happen.

What to expect from changing the default setting to Maximize My Battery Health

Changing the default setting to Maximize My Battery Health causes the following:

• This setting results in a reduced run time between charges, because it limits the charging capacity of the notebook’s battery to 80% of the currently available full charge capacity.

• You will continue to see the battery charge at 100% in the Windows icon tray, with 100% representing the new, adjusted full charge capacity.

• The change to Maximize My Battery Health has no impact on the system performance.

Thank you for the link. Right below the paragraphs you were citing there are two boxes. The second one states:

Note: After this update, if you are running the Windows 11 operating system, a small heart icon is displayed in the Windows icon tray. This heart icon indicates that a battery health feature has been enabled.

I do not have a heart in the icon tray.

I described this behavior already a year ago: https://h30434.www3.hp.com/t5/Business-Notebooks/Dragonfly-G3-HP-Power-Manager-not-working-cannot-ch...

I had the same problem until I updated to the latest version of Windows 11
