Chrome OS will help reduce battery drain — eventually

Google’s Chrome OS will eventually help Chromebook batteries last longer, but not yet. Chrome OS 105, which includes the new feature, is still two versions away.

The feature works by throttling inactive tab CPU load after 10 seconds of inactivity. Current versions of Chrome only idle a tab after five minutes of inactivity. By reducing that time to 10 seconds, open tabs will put less demand on the CPU, which equals less battery drain.

This is especially useful for people who operate their Chromebooks with dozens of tabs open across multiple windows. Students and professionals who use Chromebooks will begin to see longer battery life between charges.

But they’ll need to wait.

“The change has to do with throttling down and waking up JavaScript on web pages.” About Chromebooks wrote on its site. “These are tabs you might have open, for example, but aren’t actively looking at or interacting with.”

However, version 105 won’t be available for the average user for some time.

Chrome OS 103 is the current version of the operating system and the one most people are using. It can be a year or more before Google releases Chrome OS 105.

Until then, Chromebook users can take some steps to save battery on their own. They can lower the display brightness and the turn down the keyboard backlight. They can unplug USB accessories when they’re not using them, and make sure there are no unused apps running in the background.

Finally, it could simply be time for a new Chromebook, and if that’s the case, check out our list of the best Chromebooks of 2022.

All these outlandish battery life claims are getting silly

How long does the battery in your chosen device last? Whether it’s a smartphone, fitness band, smartwatch, laptop, or anything else, has it met or exceeded the claim made by the manufacturer? I’m willing to bet it hasn’t, or at least doesn’t do so on a regular basis, and that’s because many battery life figures published these days seem to be plucked out of thin air, and then a situation is constructed around it to make it work.

It's all getting rather silly, but is there anything that can be done about it?
Battery life information matters
Knowing the approximate length of time the battery lasts in our mobile device of choice is important. It informs us about whether it’s OK to skip charging if we’re short on time, if we must take a charger on a long weekend away, or if using a phone for GPS in the car will kill it before arriving at our destination.
