Since the display is one of the biggest users of battery power, save big on battery life by turning the brightness level down to the lowest comfortable level.

2. Avoid updates while running on battery.

While Chrome will update in the background, avoid other software updates while running on battery to save battery life and CPU resources.

3. Unplug unneeded devices

To save battery life, remove other devices like phones that are charging or headphones. Conversely, when not using the Chromebook but a power source is needed, you can charge other devices from the Chromebook as long as the machine is powered on and unlocked. For more information, see: How to use USB ports to charge other devices - Chromebook.

4. Turn off Bluetooth.

Bluetooth is a powerful technology that uses power. If the Chromebook has been set up for Bluetooth, but Bluetooth is not in use, turn it off. Click the status area on the taskbar, select Bluetooth Disabled from the Settings window, and click the Bluetooth symbol Bluetooth icon. Bluetooth will then show as disabled Disable bluetooth.

5. When inactive, lock the screen

Chrome OS is designed to maximize battery life. As a result, there is no native setting available in Chrome OS to change the length of inactivity before the Chromebook enters sleep mode. Screensavers are unsupported since they impact available battery life. To make the most of the battery, enable screen locking. See this link for more information: How to setup and remove screensavers and screen lock feature on a Chromebook.

6. Turn off the Chromebook completely

Turn off the Chromebook completely when not in use. For more information, see Sign out or turn off your Chromebook.

7. Close out unneeded web pages or applications

Most web pages and apps refresh frequently to provide updated information. To see what is currently open, press the Windows Switcher key Currently open, then close out all unneeded apps. Chrome OS supports a feature that lists which web pages or apps have used the most battery charge. To find this, click the status area on the taskbar, then Settings. This will open the Settings window. Under Device, click Battery. A list of websites and apps will show in the new window, along with the percentage of battery consumed.
