No more envy of your friends' iPhone which never become slow and battery hungry after lots of apps installed. With Greenify, your Android device can also run almost as smooth and lasting as the first day you have it!
Greenify help you identify and put the bad behaving apps into hibernation when you are not using them, stop them from battery leeching, memory hogging and stealthy running, in an elegant and unique way! They could do nothing without your explicit launch, while still have full functionality when running in foreground. Like what iOS apps act!
The built-in App Analyzer will analyze and show apps in your device that keep running persistent services and those launch itself automatically on a regular basis (when network connectivity changes, or every time you unlock your device, install / uninstall / update your apps, etc).
NEW: Non-root working mode is now supported in 2.0+, but still in early stage. It currently lacks auto-hibernation due to privilege restriction. Use "Hibernate All" shortcut (widget) for convenience. On Android 4.1+, an accessibility service can be activated to automate the manual hibernation procedure.
Compared to other popular tools aimed for the similar purpose, Greenify give you the unique experience:
◆ Unlike the "Freeze" feature in "TitaniumBackup Pro" that totally disable your app, you can still use your app as usual, share content with it, without major uncomfortable impact on user experience. Greenify is nearly transparent! Set and forget~
◆ Unlike "App Quarantine", you can launch greenified apps in any way as usual. No more crafted app-launch widgets, no more manual disabling.
◆ Unlike "Autostarts", you can benefit almost all its advantages, but never need to deal with the complexity and risk of obscurely named app components, and never lose functionality when app is actively running.
◆ Unlike any "XXX Task Killer", your device never fall into the cat-mouse-game of stealthy-running and aggressive killing, which unnecessarily consumes much battery juice. Since all greenified apps will be put into hibernation until the next time you launch them, there is no need to "kill" them during the hibernation.
As the bottom line, Greenify do need a background persistent "Cleaner" service to put the greenified apps back into hibernation when you are not actively using them. It is designed and implemented in extremely light-weight, with an average RAM footprint at 2M in total, and nearly zero CPU and battery consumption.
IMPORTANT: Greenifying an app implies that you are aware that all the background functionality of this app will become out of service during the hibernation except when you are using this app. The background functionality includes but not limited to:
* Persistent background services
* Broadcast receivers, which respond to global device events, such as network state change, SMS reception.
* Alarms, which activate background task at specific time or interval.
* Widget update. Widget should display but never update because periodic update involves background task.
* Push messages. Push is also disabled since it would activate background task on Android, unlike iOS which just shows up messages to user.
Please DO NOT greenify alarm clock apps, instant messaging apps unless you never rely on them. Please be sure to verify the impact of greenified apps on which you heavily relies.

A: Sorry, Android 2.x lacks a core mechanism that Greenify mainly depends on. It's impossible to achieve equivalent functionality in Android 2.x. If possible, please consider upgrading your device to Android 4.x (CyanogenMod is a good choice if no official 4.x upgrade). If you are out of luck in upgrading, you can also try one of the alternative tools I mentioned in the app description of Greenify on Play store, such as "App Quarantine" (for most users) and "Autostarts" (for super users).
Q: Which apps should I greenify?
A: In short, don't hibernate all (or most of) your apps! App Analyzer of Greenify only shows apps which have POTENTIAL impact on battery consumption or device performance (click the icon "i" of each section for more details), it doesn't mean they actually have. You are suggested to only hibernate those you seldom use, plus the apps you are sure have negative impacts, most probably identified by the "Settings - Battery" of your device, or 3rd-party diagnose apps, such as Wakelock Detector and BetterBatteryStats (for power users).
"Running in background" does not mean it has definite impact on battery consumption or device performance. Experienced developers can also reduce the memory footprint of background service as low as several megabytes, which is negligible in most middle-to-high end devices with 1~2G RAM.
"May slow down the device" also does not mean it has definite impact on device smoothness. Android caches the process of apps regularly run, thus significantly reduced the cost of launching it in background.
Q: It seems that automatic hibernation is not working.
A: That is most probably caused by your root management tool. Because some root management tool require re-authorization after app update, you may have missed the confirmation dialog, since Greenify requests root privilige when screen is off.
If you are using SuperUser and confirm root privilege is granted to Greenify, there's a high chance SuperUser is not working correctly for background root privilege requests on your device. Most user with this issue got it solved by installing SuperSU instead of SuperUser. You are suggested to have a try.
Q: I want to greenify system apps!
A: First of all, it's not safe to greenify system apps, because system apps are responsible for core functionalities of your device and they are usually essential components for other apps. Android OS also protects system apps with far more privileges than mornal apps, that stops Greenify from effectively putting them into hibernation.
Q: I still want to greenify system apps, and I can accept any bad consequence!
A: If so, you can try converting non-critical system apps (such as apps bundled by carriers) into normal apps with the help of Titanium Backup or similar tools. Reboot your device, then greenify it as normal. Or you can try the experimental feature in donation version to directly greenify system apps.
Q: Degreenified apps (or greenified apps with donation package) still got no push notification!
A: Unlike iOS's pure text push messages, push notification in Android involves background task. So hibernation does stop the push notification from working. Even after you degreenfied these apps (removed from list), you may still need to reactivate the push registration in them.
Different apps have different procedures, some will automatically re-activate it, some with (push) notification settings can be easily turned off and on again, and some may need you to logout and login again.
An experimental feature "GCM push for greenified apps" (in donation package) is aimed to enable push notification for greenified apps if they use Google Cloud Messaging for push notification (a little GCM icon will show up for GCM-enabled app in App Analyzer). This can be extremely useful for some apps if your usage pattern mainly depends on the push notification from them, but don't want the overhead of background activities.
You may still need to reactivate the push registration as mentioned above if the push notification stops working occasionally.
Q: Some of my greenified apps (e.g. Google Maps) seems not hibernating.
A: In short, don't worry about frequently awake apps. It will still hibernate in minutes after screen goes off, thus hardly add observable battery consumption. Use battery statistics in settings or "BetterBatteryStats" to confirm that.
While most greenified apps will stay in hibernation quietly, some apps do break hibernation, due to being woken up by others. Some known cases include enabled account sync, backup agent, and explicit launch by other app.
Since version 1.45, Greenify will now automatically turn off directly involved account sync of greenified apps when going to hibernate, to avoid the periodic account sync wake them up. For backup agents, Greenify will NOT disable them, to ensure your backup of app data is always up-to-date. As backup usually does not perform often, they are thus unlikely to be waken up often.
Google+ and Facebook are typical example of explicit launch by other app. 3rd-party apps with Google/Facebook login wake up Google+/Facebook app when they need to use the login information.
Since Greenify is designed to not break any explicit usage of greenified apps, these behaviors are considered "normal", and will NOT be "fixed". To clear out your unease, Greenify will still put them into hibernation when standby to protect your battery consumption.
Q: Could you add an option to allow for a scheduled hibernation every x minutes?
A: I have been considering this option, but at last, I found it a task "too complicated to satisfy all". Some users need the option "night mode" which means scheduling on specific time, some users need the option "every x minutes" which means scheduling on fixed periods, and even worse when some users asked for separate schedules for each greenified app. Still, it is not the end, I received a mail asking for hibernation scheduling by network state.
Then, I realised that if the scheduling feature is implemented, not only this feature itself will be a bottomless pit, but Greenify will also become a complicate monster that most users will get stuck in tuning those options. It is obviously not my intention.
So, let's just leave the complication to professional tools like Tasker and Llama. They handle scheduling far better than I could achieve. Thus Greenify could focus on its core functionality and evolves a bit quicker, since I don't have much time developing this app.

I wish Greenify could arouse app developers to actually recognize and respect the "device experience" (apart from user experience in narrow sense) in an offensive way, for a better Android ecosphere.
I'm a software developer in one of the largest Internet company in China. In my spare time, I'm also an Android geek. As both Android developer and super user, I care a lot about end user experience not only within our products, but also across the whole device. Unfortunately, many developers are unaware about the device-wide impact of their app behaviors, or less attentive when implementing new features. As a developer, I even had to give up some tempting feature possibilities to achieve better device experience. It's a hard choice, but worth it.
Looking at the apps around us, persistent background service, aggressive broadcast (event) receivers, and frequent alarm triggers are widely abused, leading to heavily degraded device experience if you use a not-so-powerful Android device with many apps installed. (I have nearly 200 apps on my Galaxy S now) Even on high-end devices, you may not notice the performance degradation, but battery drain was still a pain. These are the main shortages of Android device, compared to iOS. You may call it the price of flexibily and freedom. But never should users bear the cost.
I was giving lectures to developers on device-experience-friendly design, but has only limited influence. I can write blogs, but how many developers will listen? At last, I chose to deliver a weapon, to all end users.
Greenify is carefully designed and implemented to help both power users and average users to recognize among your installed apps which one may affect the device experience and give you the choice to "greenify" it, as a struggled balance between app functionality and device experience.
It is not adviced to feed all your apps to Greenify, because hibernation also has a price, despite inexpensive. Since hibernated app can no longer run by itself, you may lose some passive functionalities, such as push notifications, content syncing and widget update. Besides that, it is also totally moved away from memory, thus you can no longer benefit from the process cache on the next launch. So you should leave the well-behaved apps out of Greenify. This will truly encourage the device-experience-friendly apps.
Greenify also benefit app developers, by giving their app longer living time on edge users' device, otherwise it might have already been uninstalled. So developers have a chance to bring improvements and new features to possibly persuade users for another try. That's much easier than converting already lost users.
"Greenify" is not a final solution, but a raise of voice! In an upcoming version of Greenify, I will even push this striving further by aggregating your voice, as a whole of the community, to be heard by the developers of the apps you greenified, looking forward to a better version from developers themself. At the same time, I will also write series of blogs here to help Android developers to achieve better device experience in designing and coding details.

I've got so many apps in this and its so nice to finally be able to control some of the crazier apps out there. I used to hate apps like the Facebook app as it would always be on and eat at my battery, this makes it usable again. I've gone back and downloaded so many apps that I stopped using due to constantly being on in the background and killing my battery.
Thank you for making this app and being completely awesome.
I look forward to a bit of an easier way to add apps, like a batch mode. That is probably my only problem with this app. I want everything in it and have to do it one at a time. XD

Great app, i hibernated Facebook, Twitter and Whatsapp, although Facebook always comes to the surface which is why i just deleted it. For the future, it would be nice if you could hibernate a keyboard, i don't know why they have to always run... Great app!!
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
