Shallow battery charge cycle after overnight shutdown – HP ENVY x360 (13-bf0000)

[DKT2023]

Hello, I have an HP ENVY x360 13.3 inch 2-in-1 Laptop PC (13-bf0000, product ID: 552D6AV).

I regularly use a USB-C hub to connect to an external monitor, so I often keep the laptop plugged into the power adapter. However, after shutting down the laptop, I usually turn off the power source and disconnect the USB-C cable to ensure no peripherals drain the battery.

The issue is that the next morning, when I reconnect the power and turn the laptop on, the battery is sometimes at 95%, and it starts charging again — even though I shut it down the previous night at 100%.

Is there a way to prevent this kind of unnecessary battery drain or automatic charging? I would like to maintain battery health by avoiding partial charging cycles like this.

Many thanks!

@DKT2023, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

It sounds like your laptop is experiencing some battery drain even when shut down, which can be frustrating, especially when you’re trying to preserve battery health.

Here are a few things you can try to minimize unnecessary battery drain or charging cycles:

HP Battery Health Manager

HP laptops come with a feature called Battery Health Manager (or a similar setting) in the BIOS. It manages the charging cycle to extend battery life. Check if this feature is enabled and set it to "Maximize Battery Health," which will limit charging to a certain percentage to avoid constant full charging. You can usually access it through:

BIOS settings during startup (press F10 during boot).

Check for Firmware Updates

Occasionally, battery or charging issues can be related to outdated firmware. Make sure your BIOS and drivers are up to date:

Go to HP Support or use the HP Support Assistant to check for updates.

Battery Settings in Windows

Windows 11 has battery settings that can also help optimize power usage:

Go to Settings > System > Power & Battery.

Scroll down to Battery Health to see if there’s any setting that allows you to manage charging thresholds.

Also, you may refer to this guide: HP Notebook PCs and Chromebooks - Improving battery performance | HP® Support

I hope this helps.

Take care and have a good day.

Evening Garp_Senchau,

Thank you for your suggestions.

I have updated all relevant firmware and the BIOS, and I’ve also enabled Battery Health Manager as recommended. However, the issue still persists.

Additionally, I have disabled USB charging in the off state and made sure to unplug all USB devices before shutdown, but the battery still drops slightly overnight and triggers a shallow charge cycle the next day.

I’m wondering if this behaviour is related to S0 Low Power Idle (Modern Standby), as powercfg /a shows that my system only supports this standby mode along with Hibernate — all traditional sleep states (S1–S3) and Fast Startup are unavailable.

Could the battery drain after shutdown be caused by background activity in S0 Low Power Idle? Is there any way to fully disable S0 mode or ensure the system enters a true power-off state?

Thanks again, and I appreciate any further guidance you can offer.

Kind regards,

DKT2023

Hey @DKT2023, 

Thank you for your response

Here are a few things you can try next:

Check for Power Settings Tweaks

Make sure to revisit Power & Sleep Settings and ensure the settings aren’t causing your system to not enter full shutdown mode:

Control Panel Power Options > Choose what the power buttons do > Change settings that are currently unavailable > Disable Fast Startup.

Control Panel > Power Options > Change plan settings > Change advanced power settings > Check Sleep settings and ensure it’s set to "Never" for both "On battery" and "Plugged in" under Sleep after settings.

Revisit BIOS Battery Settings

Since you’ve enabled Battery Health Manager, double-check the specific settings under the BIOS to make sure you are using the appropriate battery threshold options. Sometimes, "Maximize Battery Health" limits charging to around 80%, which can be a good setting for maintaining battery life.

I hope this helps.
