Greenify: The Ultimate Battery Saver for Android


Featured as Lifehacker's Top 1 Utility in 2013 Best Android Apps (link), and recognized by Android Authority as one of the Top 3 Best Root Apps (link), Greenify is a must-have application for Android users.

Maximize Battery Savings


With features like "Aggressive Doze" and "Doze on the Go", Greenify helps you maximize battery savings on Android 6+ devices, even without root access! Detailed explanations are available in the settings.

Keep Your Device Running Smoothly


Never let your phone or tablet slow down or drain battery after installing numerous apps. Greenify ensures your device runs almost as smoothly and lasts as long as it did on the first day!

How Greenify Works


Greenify identifies and puts misbehaving apps into hibernation when they are not actively used. This unique feature prevents them from lagging your device or draining your battery. While in hibernation, these apps can do nothing without your explicit launch, yet they retain full functionality when running in the foreground.

Report Bugs


If you encounter any issues, please report bugs in the XDA forum or the G+ community.

Your Privacy Matters


Greenify NEVER collects your personal data, despite utilizing accessibility services. It simply automates the hibernation process for your convenience.

Important Notes



  • Greenifying an app: Be aware that all background functionalities (services, periodic tasks, event receivers, alarms, widget updates, push messages) will be disabled during hibernation, except when you actively use the app.

  • Do not greenify: Alarm clock apps and instant messaging apps unless you do not rely on them. Always verify the impact of greenifying apps that are critical for your usage.

  • Background Services: Greenify requires background running services for auto-hibernation to function effectively. It is designed to be extremely lightweight with nearly zero CPU and battery consumption.
