It's great that today's phones have LTE, NFC, GPS, Wi-Fi, and Bluetooth, but do you really need all five activated 24 hours per day? Android keeps location-based apps resident in the background, and the constant drain on your battery will become noticeable, fast.
Where are you? is an application that automatically turns unnecessary hardware radios off depending on your location. If a known wifi network is in range, it will automatically connect to it, turning off mobile data. When you leave your house, it will switch to mobile data connections. Also, if the display is off, all connections will be disabled.
Don't worry, you are not going to loose any watsapp at all! Autosync is enabled every 10 minutes to check if someone is thinking about you!
3 "Save battery" modes:
1- light (wifi/data on/off automatically)
2- moderate (screen off, connections off. Data check every 10 minutes)
3- extreme (screen off, connections off)
Save battery with "Where are you?"
Greenify plugin is needed to automatically hibernate apps running in background.If not installed, the app will redirect you to the playstore link.
