The battery test helps the user diagnose weak batteries in the devices being tested. The test will put stressful loads on the system’s memory and CPU components for a set duration in an attempt to cause a higher power draw on the battery. The total charge expenditure is tracked over the length of the test and is then evaluated against the set threshold of percent charge lost that is allowed for the test. The battery test requires a minimum charge of 50% before the test can begin. If the system’s battery doesn’t have sufficient charge, the battery will need to be charged for a small duration before the test begins. This duration, as well as the discharge test duration, can be modified via the settings screen.
