When charging a device, it's important to ensure that it is connected to a compatible power source to avoid damage. Charging should ideally occur in a cool, dry environment to maintain battery health. Conversely, when disconnecting from power, it's best to avoid abrupt removal of the charger to ensure the device safely transitions from charging mode. Always follow manufacturer guidelines for optimal charging practices.
