title: Optimizing battery usage of a Defold game
Battery usage is mainly a concern if you are targeting mobile/handheld devices. High CPU or GPU usage will quickly drain battery and overheat the device.
Refer to the manuals on how to optimize runtime performance of a game to learn how to reduce CPU and GPU usage.
If you are creating a mobile game which doesn't make use of the device accelerometer it is recommended to disable it in game.project to reduce the number of generated input events.
