Battery Life - Page 29

Battery life refers to the duration that a rechargeable battery can operate a device before needing to be recharged. It is often measured in hours or cycles, indicating how long the battery can maintain a functioning charge under specific conditions, such as usage patterns and device settings. Factors affecting battery life include the capacity of the battery (measured in milliamp hours, mAh), the efficiency of the device's components, and how intensively the device is used (e.g., screen brightness, application usage). Battery life is a critical metric for consumers when evaluating mobile devices like smartphones, laptops, and tablets, as it directly impacts usability and convenience.
