If you want to extend the lifespan of your laptop battery, it is important to keep the charge-discharge cycle from reaching extremes. This means that you should try to prevent the battery from completely draining down to zero and also avoid charging it to 100%. Doing so will cause less strain on the battery and keep it in good condition for a longer period. While you need to pay attention to prevent your laptop battery from getting discharged completely, you can automatically adjust a few settings on your machine to ensure that it does not charge above 80%.

On Lenovo Laptops

  1. Open the Start menu, type Lenovo Vantage and click on the application when it appears in the search results. If it is not installed, you can download and install it from the Microsoft Store.
  2. When the Lenovo Vantage application launches, click on the 'Device' tab on the top right.
  1. Click on 'Power' under 'System Tools'.
  2. Scroll down and click on the 'Conservation mode' toggle to turn it on. If you're using an older version of the program, go to the Power menu from the Device tab to limit your battery charging. Once you enable it, your battery will not charge over 80% of its full capacity.

On HP laptops

You cannot set a limit on the battery charging in all HP laptops. This is only possible on certain business-centric machines through the BIOS.

  1. Turn off your HP laptop and connect it to a power source.
  2. Turn it on by pressing the Power button and then press the F10 key repeatedly to enter the HP BIOS Setup Utility.
  3. Head to the 'Advanced' or 'Configuration' tab using the navigation keys on your keyboard.
  4. Locate the 'Adaptive Battery Optimizer' option and set it to 'Enabled'.
  5. You may need to go to 'Power Management Options' and then 'Battery Health Manager' before selecting 'Maximize my battery health'.
Note: Depending on your HP laptop, the UEFI or BIOS menu may appear differently. However, you should find the 'Advanced' or 'Configuration' tab if your system supports it.

On ASUS laptops

On ASUS laptops, you have the MyASUS application, which lets you set a battery charge limit easily.

  1. Then click on the 'Battery Care Mode' toggle under the 'Power and Performance' section and turn it on.
Note: Asus laptops have an 'Instant Full-Charge Mode' that lets you charge your laptop to 100% for 24 hours, which can be handy if you are traveling or need to use it for an extended period. After 24 hours, the charge will again be limited to 80%.

Things to know

  • Laptops from different manufacturers usually come with software that lets you limit the battery charging easily but they may not be available on all models.
  • Such software may either let you set specific charge limits or may have a feature that automatically controls it. If you do not want to manually control how your battery charges, the automatic feature can be very useful.
  • If your laptop does not have any manufacturer-provided software for setting a charging limit on your laptop battery, there are certain third-party options you can use for the purpose.
