The app is intended to help to save energy by deactivating certain functions when not in use or to specified intervals. However, the partially faulty translation and the complicated setting structures complicate relations. In addition, for example, are not unnecessarily prevented in the background operating services, which GreenPower is not a competitor to Greenify ever. Many services such as WLAN switch among Android anyway in the power saving mode, even without GreenPower. GPS and Bluetooth, you can, if necessary, even enable / disable. The App also requires the phone ID.
Conclusion: If you take the time or have to set this app and to check the settings are correct afterwards, and its WLAN, BT or GPS can manually disable and thus saves one more app and data suckers in background.
