So I recently bought a new HP Pavilion 15 cw and the life expectancy of the battery would normally be around 8-10hrs. But it won’t last longer than 2-3hrs even on batterysaving and low brightness.
Any help? Thanks in advance

Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community!
I understand you are having issues with battery not working as well as with the low brightness on your HP notebook. Don't worry as I have a few suggestions which should help you resolve this issue.
To provide you with an accurate solution, I'll need a few more details:
Did this happen after a recent software update or upgrade?
Have you tried to uninstall and reinstall the battery drivers from device manager?
Have you tried to update the Bios?
Have you checked if the issue persists even in the Bios for the low brightness?
In the meantime, let's try these steps here:
Perform a Hard reset on the notebook: A power reset (or hard restart) clears all information from the computer's memory without erasing any personal data. Performing a power reset might fix conditions such as Windows not responding, a blank display, software freezing, keyboard stops responding, or other external devices locking up.
Next thing, please try these few steps to enhance battery life.
- Make sure that the Windows 10 power plan is set to Balanced Performance to conserve battery power
- Consider which programs you are running; some programs, like graphics-intensive games, will deplete the battery faster
- .Reduce the convertible’s screen brightness to conserve battery power
- Remove peripherals like external hard drives from the convertible while they are not is use
Please follow the steps to uninstall Microsoft ACPI-Compliant Control from Device manager:
Unplug the charge and use the laptop until the battery drains to 15%.
Turn off the laptop and turn it back on after 30mins.
Reinstalled Microsoft ACPI-Compliant Control Method Battery under device manager,
Restart the computer and the issue should be fixed.
Also, Go through them all and let me know what you have determined is causing the issue. The first document has the most relevant troubleshooting if your battery appears to be not charging.
I would suggest please update the Bios and Chipset drivers and graphics card drivers on your PC from our HP support website, using this link: http://hp.com/drivers Select the country and language. Enter the product# and follow the on-screen instructions.
Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.
Refer this link to know how to use HP support assistant.
Battery Does not Power Notebook or Hold a Charge
HP Notebook PCs - Testing and Calibrating the Battery (Windows 10) (Skip the steps if you have already performed).
Next thing, I would suggest here is to run the test on the battery from F2.(Click on Component test - Scroll down to Power)
Please remember to capture the failure ID for further assistance.
Hope this answers your question.
Good luck and keep me posted about the developments. If this helps, please mark this as “Accepted Solution” as it will help several others with the same issue and give the post a Kudos for my efforts to help. Thank you and have a great week ahead. 🙂

I have the same issue here. I also performed these tests and practices:
- updated windows to the latest version and updates
- unistalled and installed again Microsoft AC Adapter and Microsoft ACPI-Compliant Control Method Battery
- Updated BIOS to the latest version
- Performed thousand of checks using HP Support Assistant, BOOT Checks, online check etc.
- disabled all softwares and used only DESKTOP to run computer ( all processes and services turned off )
- I lowed down the brightness of the laptop and other services that consumes battery
- performed a battery circle such as draining the battery to 0% and recharged again to 100%
- disabled Touch-Screen
- different thousand, million other tests...
The problem is the same, the battery lasts only 2-3 hours while in the spec of the product says: Up to 9 hours (mixed usage), Up to 7 hours and 15 minutes (video playback), Up to 6 hours and 15 minutes (wireless streaming).
Now imagine using the laptop to the fullest capacity; it won't last 1 hour.....
