The problem is not that the battery will continue to receive a charge without stopping after reaching 100%, as modern power management systems control the charging process, but that the lithium battery remaining at a very high level for long periods may accelerate its deterioration over time.
Microsoft says that keeping the battery at 100% all the time can cause it to decline faster, which is why some Windows devices provide the “Smart Charging” feature, which sometimes prevents the battery from reaching a full charge in order to maintain its health.
The way this feature works varies depending on the manufacturer, so the user can check the battery settings or the device management program to see if there is a feature to determine the charging percentage.
Heat also remains an important factor, so it is recommended to avoid placing the computer on surfaces that prevent ventilation, such as a bed or pillow, especially while performing heavy tasks.
