Abstract: In one example, an electronic device state may be set based on user activity modes. The electronic device may include a battery; a power adapter; a sensor device; a processor; and memory storing machine-readable instructions to cause the processor to: determine, using sensor device data, which one of a walk mode and a backpack mode the electronic device is in, where the electronic device is in motion during the walk mode, and the electronic device is in motion and is disposed in a bag during the backpack mode; and where the machine-readable instructions set the electronic device to a device ready if the electronic device is in the walk mode, set the electronic device to a low power state to reduce battery power usage if the electronic device is in the backpack mode.
