Greenify

Battery drain and sluggish performance plaguing your Android device? Battery optimization app Greenify stops misbehaving apps from consuming resources in the background, restoring your phone to like-new responsiveness and battery life.

Greenify identifies apps that waste battery and lag your device, then intelligently hibernates them when you're not using them. Unlike crude task killers or app freezers, hibernated apps remain fully functional when you launch them directly—they simply can't run in the background or respond to wake-up signals. It's a smarter approach that mirrors how iOS manages apps, giving you control without sacrificing usability.

Works both on rooted and non-rooted devices. Auto-hibernation on non-rooted Android 4.1+ phones requires enabling experimental features. The background service that powers this automation is remarkably lightweight, consuming less than 5MB of RAM with virtually zero CPU and battery impact.

Why Greenify outperforms alternatives: Unlike freeze tools that completely disable apps and require manual unfreezing, or task killers that trigger a never-ending cycle of aggressive background process killing, Greenify maintains a balanced approach. You get the battery savings without the operational headaches. Compared to interrupt-based app management systems, Greenify avoids the complexity and risks of manually disabling obscure app components.

Key features include identifying resource-hungry apps, selective hibernation based on your usage patterns, compatibility with device shortcuts for quick activation, and a privacy-first design that never collects personal data despite using accessibility services. The app respects your workflow—hibernated apps stay dormant until you explicitly open them or another app requests them.

Important: Hibernation disables background services, periodic tasks, push notifications, and widget updates for affected apps. Avoid hibernating alarm clocks, messaging apps, or other services you depend on receiving notifications from. Test the impact before hibernating critical apps.

Greenify has earned recognition from major tech reviewers for delivering measurable improvements in device performance and endurance. Restore your device's speed and battery longevity with Greenify today.
