Anything on your Chromebook that's tapping into the memory resources is going to eat up battery life. If you're plugged in it's not a problem, but when you're facing impending battery death you may need to sacrifice some things to squeeze out extra life.
The major hogs tend to be Google's core services, like Drive and Gmail. But Chromecast and web chat can quickly gobble up the memory, too. Any web apps or extensions you install may also run in the background.
From the Task Manager you can disable any service that you wish — but keep in mind, this can cause things to go a little wonky. If you disable the Save to Drive or Pocket extensions, for example, you won't be able to perform those actions. Proceed with caution if this is new territory for you.
You can two-finger-press or right-click on each of these processes to get more information, though some of it is pretty technical. It's also handy to sort the process by memory use to focus on the biggest offenders. Just click on the memory tab at the top right to do so.
There's another option if you're really looking to dial back battery life: Sign in to your Chromebook in Guest Mode. The advantage here is that Chrome won't load all the extensions and apps you have installed under your main profile, leading to a leaner build.
Putting it all to the test
I tested all these tips in a mostly-scientific method using a Toshiba Chromebook 2.
First, I left my Chromebook using its standard settings, turned the brightness all the way up, and ran the longest YouTube video ever until the battery died. The video can go for days, so it's a solid test method for checking out your Chromebook's battery life.
Then I repeated the process in a battery-saving optimized state. Bluetooth was turned off, brightness was set to 50 percent, and the video was played in an Incognito tab in Guest Mode. This meant fewer services were running, letting the Chromebook devote its energy to playing the awful-looking video.
With the standard settings, my Toshiba Chromebook 2 managed just four hours and 18 minutes before giving up the ghost. Using the battery-optimized settings brought it up to 6 hours and 47 minutes — a difference of more than two hours. That's not a bad round of battery life for a relatively inexpensive laptop! Now imagine I was just working on Google Docs. The battery life would likely jump up even more significantly.
