Google plans to launch ChromeOS 134 in March 2025. The latest version of the operating system for Chromebooks will birng some new features, one of which will help extend the battery life of your Chromebook.
Once ChromeOS 134 is here, you’ll be able to set a maximum battery charge limit so your laptop will never fully charge. Why? Constantly charging a battery to 100 percent shortens its lifespan, so you get more overall lifespan out of it if you stop short. (The optimal battery charge window to minimize wear and tear is between 30 and 70 percent.)
The new feature will be automatically enabled when ChromeOS 134 launches, but the battery charge limit will remain at 100 percent by default. If you want to protect your laptop’s battery lifespan, you’ll have to adjust the charge limit yourself when available.
