The Power Hungry Browser
Google Chrome is notoriously resource-intensive. If you have a dozen tabs open, the browser will consume massive amounts of RAM and force your CPU to constantly process background JavaScript, aggressive advertising animations, and hidden video players. If you are working on a laptop while traveling and do not have access to a power outlet, running Chrome normally can drain your battery in a matter of hours. To solve this, Google recently introduced a dedicated “Energy Saver” mode that drastically throttles the browser’s performance to extend your laptop’s battery life.
How to Enable Energy Saver Mode
You can activate this feature directly from the main Chrome settings menu; no hidden developer flags are required.
- Open the Google Chrome browser on your laptop (Windows or macOS).
- Click the three vertical dots (⋮) in the top right corner of the window.
- Select Settings from the dropdown menu.
- In the left-hand sidebar, click on Performance.
- Look for the section titled “Power.”
- You will see a toggle switch labeled Energy Saver. Click it to turn it On.
Customizing the Trigger
Once the feature is enabled, you have two options for how it behaves, located via radio buttons directly beneath the toggle switch.
- Turn on only when my battery is at 20% or lower: This acts as an emergency reserve. Chrome will run at full speed until your laptop is almost dead, then heavily throttle itself to buy you enough time to finish your work and save your documents.
- Turn on when my computer is unplugged: This is the recommended setting for travelers. The moment you pull the power cord out of the wall, Chrome immediately drops its frame rate, restricts background tabs, and disables smooth scrolling, ensuring your battery lasts as long as physically possible for the entire flight.
