What is meant by the term runtime in relation to a battery?

The term runtime in relation to a battery refers to the amount of time a battery can successfully power a device, such as a computer, before it needs to be recharged or replaced. This measurement is crucial for users who rely on the portability of their devices, as it directly influences usage patterns and workflow efficiency.

For example, if a laptop has a runtime of 10 hours, it indicates the duration the device can operate on a single charge under typical conditions. This concept helps users assess whether their device can meet their needs, especially for activities that require extended usage without access to a power outlet.

Runtime is often influenced by factors like the device's power consumption, the battery's capacity, and the efficiency of the overall system. Understanding this term is vital for anyone working with laptops and mobile devices, as it directly affects performance and user satisfaction.
