ChromeOS now has charging and battery state sounds to inform you about your device's battery, and help avoid dead battery surprises. Below is a list of the new sounds you'll hear based on the status of your device:

• When you plug in your device to charge


• If your battery drops below 15%


• If you unplug your device and your battery is below 15% charged


• Charging and battery sounds respect your volume settings, so if your device is muted, the sounds won't make noise.
