Charging indicator
— battery status indicator is a feature found in battery-powered devices (refer to "Power"). The design and capabilities of this indicator can vary. The simplest form is an LED or a set of LEDs that change color and/or flash to convey battery status. For instance, green might indicate a normal charge, red could signal a critically low battery, and blinking might indicate that the battery is currently charging. More advanced indicators exist as well, including those that display the exact percentage of battery charge on the device's screen or on a connected smartphone. Regardless of the specific design, this feature makes it easier to monitor the battery's condition, reducing the risk of unexpectedly running out of power.| charging indicator | clear | Save List |
