'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form.

Note what it says on that page!
WARNING: EXPERIMENTAL FEATURES AHEAD! By enabling these features, you could lose browser data or compromise your security or privacy. Enabled features apply to all users of this browser. If you are an enterprise admin you should not be using these flags in production.
I've been using this feature in the beta version of Google Chrome for a month now and haven't suffered any ill effects, but if you are at all worried about bugs or crashes and such, this feature isn't for you.
If you do want to try out this feature, type the word "Battery" in the search box and look for the flag called "Enable the battery saver mode feature in the settings" in the list. Alternatively, you can type
into the address bar and press Enter to go there directly.
Find the flag, change the drop-down menu for the flag to Enabled, and then click Restart to apply the changes.
3. Select when the battery saver feature will activate
Once Chrome fires up again, click on the three-dots menu in the top right of the window and select Settings. There you should find an entry for Performance.
Make sure Energy Saver is toggled on and you'll see your two options:
To extend your device's battery for a long road trip or plane ride, turn on Energy Saver.
When Energy Saver is on, you may notice changes in gaming and video performance.
And that's all there is to it.
As I said earlier, I've had this setting enabled on both Windows and Mac systems for the past month, and not noticed any ill effects. It's hard to quantify how much battery life I gained, but there are days when I'm a very heavy Chrome user, and I did find that battery life was holding out a lot better than usual (I had the "Turn on when my computer is unplugged" setting enabled).
If you want to roll this setting back, head back to the "Enable the battery saver mode feature in the settings" flag and change the drop-down menu for the flag to Disabled.
