To extend your battery's health, you can use Optimized charging on your Chromebook.
If your Chromebook spends extended periods of time at full charge, your battery capacity reduces over time. To keep the charge level less than 100% for a period of time, Optimized charging delays charging your Chromebook to full.
Turn on Optimized charging
Important: With Optimized charging on, sometimes your device won't fully charge.
To analyze your daily charging patterns and charge Chromebook based on predictions of your unplug time, your Chromebook uses machine learning. It's designed to charge your device fully before you unplug it.
Based on predictions of your daily Chromebook use, Optimized charging turns on. If you unplug your device after it's fully charged, Optimized charging won't turn on.
