Can I enable/disable Adaptive Charging on my ChromeOS device?
Google and Acer have introduced Adaptive Charging on some Chrome operating system Acer devices to prolong the total battery life of the lithium-ion batteries. In general, lithium-ion batteries degrade quicker if they spend too much time at full charge. Adaptive Charging allows you to charge the battery to 80% capacity and it completes charging to 100% based on a machine learning prediction of when you will unplug the device.
When Adaptive Charging is enabled, the battery pictogram has a green pill around the battery percentage indicator. See the image below for reference.
If your device is not managed by an administrator, the Adaptive Charging feature is enabled by default. Acer recommends keeping Adaptive Charging enabled, as it will help extend your battery’s life. However, it can be toggled off if deemed necessary.
There are different methods how to activate or deactivate this feature:
- Via Settings.
- Via Quick Settings.
1) How to enable/disable Adaptive Charging on ChromeOS devices via Settings
- On the left side of the taskbar, click on the Launcher button (◯ icon).
- Then click on the Settings button (⚙ icon).
- In the left pane, click on Device.
- Then in the right pane, click on Power.
- Go to the Adaptive charging section, see the image below for reference, and toggle the feature on or off.
2) How to disable Adaptive Charging on ChromeOS devices via Quick Settings
- On the right side of the taskbar, click on the green pill with the battery percentage indication. This is a quick link to the Power page in the Settings menu.
- Go to the Adaptive charging section and toggle off the feature.
For the Chrome devices which are enrolled in a domain and are controlled by an administrator, the administrator will either enable or disable Adaptive Charging according to the organization’s policy and lock the feature; the toggle is greyed out and there is a building icon in front of the toggle. See the image below for reference. If Adaptive Charging is locked, you will not be able to toggle the feature on or off.
When Adaptive Charging is enabled and your device is predicted to be unplugged in less than 8 hours, you will see a notification pop up after the battery reaches 80% notifying you about what it does and when the battery should get fully charged.
If you do not want charging to be held at 80%, click on the Fully charge now button in the notification window, see the image below for reference.
Note: This notification pop-up appears for 8 seconds. When it disappears, you can still access it in the notifications tray.
If the Adaptive Charging feature predicts that you will not unplug your device within the next 8 hours, there is a separate notification shown once. Once your device starts charging the battery to the maximum, these notifications will be dismissed.
