While most of you are running Chrome OS 103, I’m testing Chrome OS 105 in the Dev Channel. I see a new flag in that version that expands upon a change from way back in version 88. And this tweaked Chrome OS 105 feature could boost Chromebook battery life.
In Chrome OS 105, I see an experimental flag at
It enables a feature called “Quick intensive timer throttling of loaded background pages” and further enhances the JavsScript timer access on background pages. It changes the grace period from the initial feature in Chrome OS 88 from 5 minutes to 10 seconds.
All of the technical bits aside, what does this Chrome OS 105 feature do in a tangible way? According to the Chromium page describing the changes:
This is expected to extend battery life. An experiment on the Canary and Dev channels did not reveal any regression to our guiding metrics and there are significant improvement[s] (~10%) to CPU time when all tabs are hidden and silent.
To be clear, I wouldn’t expect a 10% boost in Chromebook battery life over what you get today.
Even so, the energy savings could be noticeable.
How many people continuously use a Chromebook with only a single browser tab open all the time? I doubt there are many and this feature wouldn’t help them. However, if you have multiple browser tabs open, something I’d bet the vast majority of Chromebook users do, then the efficiency from this Chrome OS 105 feature will kick in.
It would take highly controlled tests for me to determine the battery boost on a Chromebook from this. So I’ll refrain from doing that and let Google handle it. In the meantime, I’ll keep the new flag enabled and see if I notice any general Chromebook battery life boost for now.
