Project Volta is an initiative by Google aimed at improving battery life on Android devices. Launched in 2015, it focuses on optimizing power consumption by enhancing the efficiency of apps and system processes. The project includes features like Doze mode, which reduces background activity when a device is not in use, and App Standby, which limits the resources used by apps that are not frequently accessed. Together, these innovations help users enjoy longer battery life and a better overall experience on their devices.
