Runtime

Back to Glossary

Battery runtime is the amount of time a battery can provide useful energy to an application. This varies unintuitively with the rate of discharge and other factors, such as temperature. For example, increasing the discharge rate can reduce the runtime faster than expected. A battery discharged at double its standard discharge rate will deliver less than half its standard runtime. As batteries degrade, runtime is reduced, and factors such as discharge rate and temperature have an increasingly significant impact.
