Warranty damage and mechanical damage are two different types of damage that can occur to a device.
Warranty damage: This refers to damage caused by a manufacturing or material defect and is normally covered by the manufacturer's warranty within the warranty period.
Mechanical damage: This refers to damage caused by external influences such as impacts, falls or incorrect handling. This type of damage is not covered by the manufacturer's warranty and requires repair at your own expense or can be covered by an equipment insurance policy.
