Greenify speeds up your Android device by putting battery hogging, always-on apps in hibernation

Remember how fast your Android device was when you first powered it on, fresh out of the store? Over time, each phone or tablet, not unlike a PC, gets bogged down with apps and user data, turning progressively sluggish. Thankfully, there are ways to get around that. Greenify, for example, is an app designed to optimize your Android device into running as smoothly as it initially did.

It accomplishes this not by deleting stale data, but by helping you identify apps that misbehave, keeping their activity and eating battery life while you aren't using them. Upon identification, it puts those apps in hibernation mode, which stops them from bogging down the device and draining its battery. Sounds neat, no?

But what happens to those apps when they are off the grid? Well, you can launch them again when you need them, or other apps call upon them. Their full functionality is preserved when they're running the foreground - it's just not active. Greenify doesn't "freeze" apps and it's not a task killer.

Greenify's App Analyzer only shows apps which have POTENTIAL impact on battery consumption or device performance. It is suggested you hibernate only those you seldom use, along with the apps you are sure have a negative impact. For that, it's best to consult your Android phone's Battery manager, or your preferred 3rd party battery status app.

Greenify doesn't support Android 2.x devices, but anything beyond Android 4.x is game! The app is free, but it requres a rooted device.

Hey, suspend apps when not in use while preserving its current state... where have I heard that before? Both of my android friends are going to be happy to see this....

Please read. Not all apps, just the apps you dont want running in background. People do want some apps running in background..!! Unlike iOS which doesnt give you the freedom.

Lets entertain your logic: What apps do you want running in background and why?

Varies in person. For me messengers, email client.

10. AlikMalix unregistered

So, in an iPhone you have to open up BBM to recieve a message, by this logic? or email will not be recieved if the email app isnt open? there will be no "push" notification unless email app is running? is this how you guys think of iOS? Come on... is that it?

"So, in an iPhone you have to open up BBM to recieve a message, by this logic? or email will not be recieved if the email app isnt open? there will be no "push" notification unless email app is running? is this how you guys think of iOS?" Where in the hell did I said all that about email not receiving stuff? Plus messengers like viber don't run when greenified. Too much overreacted confusing post.

um.. sorry dude, didn't know you weren't replying to the posts above... here, I'll explain... in post #3 iampun33t said that iOS does not give you the freedom of running apps in background.. so, I wanted him to elaborate on which apps he (or other android users) prefer to run in background. You said "messengers and email client". It was natural for me to assume that because of post #3 and your post that some of Android users think that iOS does not run background apps and other tasks due to assumption that iOS does not multitask. What I was trying to get to, is to point out that Apple has done a great job of prioritizing background functions that work AUTOMATICALLY to enhance proper battery and processing power as needed. This is also the reason I asked "Why?" in post #5. Because for me, for example, it is important that my maps run in background while i'm on the phone talking - but I dont want to miss my turn, thus even if i'm talking on phone - I will not miss my turn --- AT THE SAME TIME, I have my reminders app tracking my location to make sure I get reminded to stop at HomeDepot to get the hardware I need on the way to the job --- AT the same time "find my friends" app to let me know when my kids leave the school ground and when they get home --- AT the same time have my video I took of the remodeling project uploaded to my harddrive thru WD MyCloud App at home (so that I already have it waiting for me in the evening).... Just want to stop this crap that iOS does not multitask...

Your reply #10 literally confused me.

23. AlikMalix unregistered

Post #3 said that iOS does NOT give users freedom to choose apps that you want running in background. That is a true fact (to a point, see app settings in iOS). What I wanted to know (Post #5) is: what apps do Android users need or prefer to run in background and why? So that I can asses if the way Apple implemented background tasks is correct FOR ME, or if Android has apps that I may need to run in background. All I'm trying to do is collect some examples why Android running all apps in background is a better option than having automatic configuration with options to limit/add app permissions in iOS. For this I've been called troll names couple times already...

Because you can decide to stop some stupid applications whose feedback you are not interested but that you still want to have there for WHEN YOU WANT. Examples: facebook and it stupid notifictions, games giving you messages, tweeter, some navigators giving suggestions you don't want, etc. Greenify stops all the ones YOU DON'T want, but leaves the one you are interested.

Thank you... did you know what you described was possible on iOS since iOS 3 (that's 2009 or before but I didnt have an iPhone back then) Also see post #34

50. engineer-1701d unregistered

think of it like if you are in maps and going some place and you need to go on a website and read and make an apointment somewhere android will still run maps in background and read out aloud the directions while you are on the internet doing reservations or if you are in a phone call being able to back out of it while talking open another app maps or weather and go to the web and check the event at the same time have all 4 or 5 or more running at the same time, android will not shut them down, i wish someone along time ago just put a line of code saying if the screen is off and no input is felt after 30 sec it stops background apps from running/suspends them. i have said this for years i do this in electrical work all the time to save power consumption

54. AlikMalix unregistered

iOS does the same thing - it reads out driving directions even if another app is running in foreground (even if it's music or radio app).

Let me stop you from here. I can see that you are confusing suspended apps and background tasks. In iOS, whenever you run an APP and then press the home button, it minimizes and might be suspended whether its process requires to be active so that its work is not interrupted (which the problem is not all app developers implements this in their app, causing them to stop immediately). In Android, these will never be suspended and will stay eating up memory in the background. Background tasks (it's Background App Refresh from iOS 7 now, Android has this but it's not mentioned) is different, it is a kind of service that is linked to the app that performs specific tasks that is intended by the app (say updating weather info, etc). To be honest, in my experience using Greenify, it actually STOPS both App and Background Tasks from running when the screen is off for minutes. This idea comes from Greenify because Android apps stays at memory when Home is pressed and even restarts if it's killed by Recent Apps unless it is force stopped. That's the purpose of Greenify. (to be honest, I don't think it "preserves their current state" either. Tried Greenifying IMs and my message won't come until it's opened). Your last, unnecessary (unless you're really a troll or apple fanboy) sentence perceives people that you are basically insulting Android users of their incapability to put up so called "intelligent multitasking" that is worshipped in iOS. Hence the reason you are called an iFan.

55. AlikMalix unregistered

EcoCare, we're talking about the same thing, but read some of the posts from some android users here - they actually believe that if you tap the home button on iOS any and every app or task is closed, shut down, and nothing else. Apple haters keep chanting that iOS has NO multitasking, zero ability for background tasks, when in fact not just multitasking but also customized delivery of information even if there are many other TASKS running silmonteniously. I'm trying to outline that the beauty of iOS is that there's no need for apps like greenify as it is all done automatically with your own preferences and the way a user sets it up. The only thing I would add to iOS (but on iPads only and maybe on 6+) is the split screen. On anything below 6 inches that's a bit too small for two apps running at the same time - but that's just my opinion. I sound like a troll because I'm desperately trying to break this notion that iOS is one-task-at-a-time deal so we can move on and talk about the interesting details of our OS's. Here's what sounds like trolling, but it's not: I prefer to deal with my daily tasks - not deal with tasks on my phone. Before you call me apple troll think about that. It is ok to disagree as you probably prefer to tweak every little thing on your phone. I do not - iOS does this Automatically based on preferences I select.

I just came here to straighten up the lines. I do agree that some of their arguments are invalid. I'm okay with your enormous effort to break that popular notion regarding iOS and the way you use your phone doesn't sound like trolling. However, it's the last sentence in your very first post that lured people to "fight" you back because I'm sure everyone believes that it's an obvious insult, causing this chaos. And your immediate response towards Apple hate in pretty much other articles made me think that you do, are an apple fanboy. Don't you think?

Add weather widget, G now, 3rd party notification app and so on. ios can not.

Yeah, and it requires root. With jailbreak You can do just the same, but iOS doesn't get sloppy over time, so go with your hater camp elsewhere.

15. AlikMalix unregistered

Dont need jailbreak, bro... iOS is already built that way years ago...

the problem is bro... even with all those, iOS battery life isn't great. but android phones have better battery life and with Greenify we can improve it further plus you don't need root to run greenify. when you don't understand the technical stuff please don't try to make an argument for the sake. technically it's well known that iOS doesn't do true multi tasking. but for the sake as you do, you can't run 2 apps at the same time in iOS. eg : you can't watch a training video while taking notes at the same time but in android we can

26. AlikMalix unregistered

I know that, I know you cannot run 2 windows on one screen on iOS, dont care for that on the iPhone, but believe me - I WOULD LOVE that on the iPad. I have no argument against that. iOS doesnt have battery, iDevices do - and believe me my iPhone 5s is only 2% shorter than Samsung GS5 when run down doing the same thing both from 100%, but after recharging to 10% both and running same tasks again my iPhone had another 1% left when Samsung died (on that 1% I played music from my harddrive at home via 4G to bluetooth speakers for 37 minutes) this was before iOS8 and my battery improved with iOS8 due to some tracking permissions improvements... (I use find my friends quite often for wife and kids) Bottom line, yes SOME android phones do have better battery - no argument, I'm happy with mine - charge it once every day and if I forget mid day next day - which is what everyone else does on average... That's not the point... All my posts above are an attempt to prove that iOS does a great job at what Greenify is designed to do, but automatically. Post #3 said iOS does not give freedom - in this case he's talking about which apps to run in background - I want to know which apps you guys run that I may need to run in background but cant... and I got NO ANSWERS (except for post #22)!!! So far I like Automatic than Rooting my device and doing it manually -- wanna weigh in: Which apps do you need/prefer to run in background?

Post 61. Weather widget, Google now widget, 3rd party notification app etc.

28. AlikMalix unregistered

Dont tell that to me tell that to the author of the article, and I quote: "Greenify doesn't support Android 2.x devices, but anything beyond Android 4.x is game! The app is free, but it requres a rooted device." Look at the article above, I'm just going from that...

@AlikMalix "Who's that tripping over my bridge?" /obvious

6. AlikMalix unregistered

well, I was stating the "obvious", I mean this is what iOS users already enjoy - apps that dont need to run in background already dont, and the ones that need to run in background already do... and there's no need for rooting/jailbreaking...

And Android users enjoy true multitasking. I know which I prefer (which is why I've never had greenify on any rooted device. And yes, I've known about it for years).

16. AlikMalix unregistered

See post #5... please respond... I'm curious.. (if you need an example see post #14)

"I mean this is what iOS users already enjoy" LOL, dude you're so delusional.

19. AlikMalix unregistered

you mind elaborating... this is a forum, you're welcome to explain yourself.. you dont think iOS users enjoy their devices? I take my time to explain my point... you just go straight for namecalling... I enjoy my devices, I'm not here to prove you out of what you enjoy - There's one thing that we all have in comnon here on PA, we enjoy reading and commenting about Tech Stuff... what's with namecalling? I like to chat about this stuff an share my experiences bad or good (there's enough of both). But before I can get into a normal conversation, I have to unburry every article from Apple Hate... Specifically how this article posted how a rooted android app lets you do what iOS already does automatically and does it very well right after I was done reading how iOS cannot do anything right... Now, by your logic, if you enjoy Android "stuff" and I don't, I get to call you delusional? is this how it works? Can we have a civilized debate, please, for once? Maybe you want to answer a simple question: What do you need/prefer to run in background and why?
