battery lowers when PC is powered down

[DavideIo]

Hello

I have a problem with my HP Pavilion x360 - 14-ba012nl

It seems that the battery lowers even when the laptop is shut down. When I restart the laptop days later, the battery % is significant lower than the moment I shut it down (sometimes it is completely uncharged, the laptop starts only after a few minutes of charging)

I'm 100% sure I chose "shut down" and not "ibernate"/"sleep" and the HP utility shows that the battery is fine. I also tried to let the lid open, to make sure I wasn't interfering with the "shut down" operations

Even if the laptop is quite old, I used it very few hours and the problem has always been there

Can you suggest any check I can do? I'm thinking mostly at some settings that may prevent a "full" shut down of the system

Thanks

This is common and not a defect. Laptops with internal batteries use that internal battery as the system (RTC or CMOS) battery to keep time. Also, Windows 8 and higher uses a hybrid shutdown which is really a form of hibernation, even if you think you are shutting down. 1-2% loss per day is normal. You can try doing an alternate full shutdown of Windows:

A full shutdown is not a 100% solution; you would just slow down the power drain.
