How to Turn On Battery Saver Mode on a Laptop

Tap each step to follow along in order.

  1. Open battery settings

    Go to Settings, then System, then Power & Battery (the exact wording varies slightly by device).

  2. Turn on "Battery Saver"

    Switching it on dims your screen brightness and limits background activity, reducing how fast the battery drains.

  3. Set an automatic threshold

    You can set battery saver to turn on automatically once your battery drops below a certain percentage, like 20%.

  4. Check your power plan too

    Choosing a "Best power efficiency" power mode trades some performance for noticeably longer battery life.

  5. Why it's useful

    When you're out without a charger and need to make the battery last, turning on battery saver can help you get through whatever urgent task you need to finish.

Stretch every bit of battery when you don't have a charger

If you left home without your charger, turning on battery saver mode reduces screen brightness and background activity so your remaining charge lasts noticeably longer.

Check your battery's overall health too

Battery saver mode helps in the moment, but it's also worth periodically checking your battery's overall health and capacity, since an aging battery drains faster regardless of your settings.

Frequently Asked Questions
