I'm at a point in my Android life where I can live without root access if I need to. I don't use very many root applications at all – I generally only use it for a one-touch reboot on phones without a built-in option in the power menu, and Greenify. I love Greenify. I don't use it for every app installed on my phone, but it's a fantastic tool when something just won't quit chomping down on the battery. I really miss automatic hibernation on my non-rooted handsets.

Now, however, that changes. By some form of sorcery, the Greenify team has figured how to enable automatic hibernation on non-rooted phones. This drastically improves the experience compared to the old method, which basically required users to force close apps manually. Oftentimes that was more trouble that it was worth, so this new feature is definitely welcome.

To get in on the action, you'll just need to enable the feature in experimental settings, and you're good to go. In case it's not working for you, there's also a "Hibernation and Lock Screen" shortcut that will kill the selected apps and turn the display off. Good stuff. 

Thanks, Ben Fisher!

    Just gimme back auto Flightmode w/o root.

    • http://www.plus.google.com/+TommyNunno yodatom10

      Probably can be done with tasker

      • Wyatt Neal

        Nope, still requires root for airplane mode. At least it did 3 months ago when I was building profiles.

  • http://www.about.me/kendallseabury Kendall Seabury

    Does this add the other things like allowing notifications on hibernated apps?

    • Rami

      If you have the Pro/Donate version, then yes: you get notifications for hibernated apps.

  • HoboJerk

    Can you give a description of what hibernation is?

    • http://retardedgeniuscomics.tumblr.com najodleglejszy

      it stops the app and prevents it from automatically relaunching by itself (as it happens when you force stop it).

  • http://SocialMediarology.com Jeremy A Williams

    Wow. Greenify (and deleting bloatware) was the whole reason I rooted...

    • mobilemann

      you still need to root to greenify lots of apps that are considered to system otherwise to greenfiy. The whole "i can do more without root" thing is basically total bullshit.

      Yeah, i can use tasker without root, but no useful plugins i have work without it. So in reality...

      • Somnambulator

        yup... no ad blocking, no xposed, not much benefit to Titanium Backup...root or GTFO!

  • Erock

    I downloaded greenify a few months ago (non-rooted). It's the first app I recommend to people. Serious game changer for my battery. I greenify every app except weather, hello sms, SwiftKey and my work email.

    • Eloy Antunez

      When you greenify though, doesn't that effectively keep any app from running? Killing notifications from those apps and such?

      • Erock

        Yep, it does stop notifications. But you don't need to greenify every app. So you could not choose to greenify Facebook weatherbug group me etc and still get notifications from those apps. You'll still have some battery drain from those, but you will still see a difference from having everything else hibernated.

        On the subject of good apps. Galaxy Charging Current for Samsung phones. Samsung had the genius idea of making their stock charger recharge their phones at half the speed they should be. (charges in 6 hours instead of 3)

        • Cerberus_tm

          It only stops notifications from applications that don't have the GCM cloud icon. Ones like Gmail and Whatsapp work fine while Greenified.

  • Ezzy

    Typo @ "something just won't quick chomping down"

    • http://www.androidpolice.com/ Cameron Summerson

      Thanks, fixed.

  • Aaron Stevenson

    Which version of the app is this? I just downloaded it from the Playstore (version 2.3.2) and I am in the beta program, but I don't have this option. Does it require the donation package?

    • http://www.androidpolice.com/ Cameron Summerson

      Nope. Are you sure there isn't another update available? It was actually released to the Play Store a couple of days ago.

      • Aaron Stevenson

        Yep. JUST downloaded it. Wasn't there. So I signed up for beta, uninstalled, and reinstalled. Still not there. What version do you have?

        Edit: The web playstore shows version 2.4, but for some reason when I install it I get version 2.3.2.

        • Aaron Stevenson

          And...... now there's an update. Oh well.

      • TheImmaculateJ

        So what's the deal? Is this for Beta users only? Because I just completed a fresh install and it's giving me 2.3.2 and I do NOT have this option available, and I'm not a beta user, and I checked and there is no update available after installing the app :

  • Christopher Robert

    Not a big fan of Greenify. Never saw any significant battery life increase from it. and always saw huge performance declines. If you use Facebook app it is probably worth it though. 9 times out of 10 if you only greenify that app you will see a huge benefit to your battery life. I personally just uninstalled the app and got better results.

    • patrick

      Another option is to use a Titanium Backup widget for quickly freezing and unfreezing the Facebook app (and whichever other battery hogging app you have installed).

      • bolski

        True, but with Greenify, it doesn't disable the app, especially if it's an app you use once in awhile (or often). Freezing makes the apps inaccessible until you unfreeze it. Greenify just prevents it from doing a wake-lock, which is what a lot of battery drain is attributed to.

        But yes, freezing is another option, especially if it's for an app you never use.

    • flosserelli

      Interesting. I have never experienced any performance hit (that I am aware of). Greenify is always one of the first apps that I install after flashing a new rom. Greenify alone won't do miracles for battery, but Greenify in combination with other tweaks will definitely help.

      • dude

        I don't know what he's talking about, I use Greenify religiously, it prevent wakelocks and improve battery life if anything, there is literally no performance penalty.

        • Christopher Robert

          There are much better ways to fix wakelocks. The performance issues have to do with how greenify effects flash memory. Linux uses RAM different from other OS types. It can actually be worse for your battery to have to fully reload apps cleared from your ram by greenify than it is to just leave them. Especially if you are using ART.

          If you have an older phone, not running KitKat it might still be worth it, but on any new device it's better to not use it.

    • yieldway17

      Earlier this week, I turned off auto hibernation to test something and forgot to turn it back on. And 3 days later realized that auto hibernation is off and my battery life was nothing different before from when I used auto hibernation. Kept it off because of it. Either Android apps has improved or Greenify is not significantly better.

    • sudhir

      greenify has major impact on ram usage compared to battery life....it basically removes apps from RAM creating more space causing less battery impact from those apps...and they claim to make phone faster which is actually happening....the battery saving is only the extra feature....

      • kandros

        no, is freeze the app so that no longer rrun background services, with xposed that became very usefull becuase you can basically turn off any background process that is there to receive notifications or updates, (whatsapp facebook ecc ecc) but still have the notification in real time thanks to GCM

        • sudhir

          i am not denying but if you check the description of the app on play store, you can see that greenify is more stressing on ram clearance which ultimately results in better battery life....i am not talking anything about the gcm and related to it...and frankly speaking, whatsapp is the only major app used nowadays for communication...facebook using people are greatly reduced coz of whatsapp n similar apps...so dont need to greenify the whatsapp...

        • sudhir

          also, u will not get too much better battery life even if you use greenify to full extent

      • Christopher Robert

        If you are concerned about RAM usage it is better to go into developer options and limit the background processes.

    • critofur

      Even if it didn't improve battery life I wouldn't use any android device without it! I don't want any apps to be running behind my back (unless I want them to, email for example). Having to choose between either just not installing an app and letting the app have it's way with my device is not a choice I'm willing to make and nobody else should have to either. I might want to use Facebook, but when I exit I don't want it checking/notifying/or in any other way "running in the background" until I RUN IT MYSELF BY CONSCIOUS CHOICE!!!

  • Aaron Stevenson

    Doesn't work with a secure key guard is set. Sad day.

    • andy_o

      Did you try PIN, or pattern?

      • Aaron Stevenson

        I tried both.

        • MrIg0Hard

          From the Dev

          Try the "Pull up" gesture on the home soft-key, which hibernates apps and locks the screen, assuming that you don't use this gesture for Google Now.

  • jjrudey

    I still use root just as much as I always did. I don't run custom roms anymore, but I definitely still use root.

  • dentou

    whats the one-touch reboot app metion in the article

  • http://www.innews.dk/ Erroneus

    It doesn't work if you have a keycode / pattern on your lock screen. Looks like I still have to get my Moto G 4G rooted for this.

      • http://www.innews.dk/ Erroneus

        Ah cool, thanks.

  • Ben F

    Woooo This was my tip :D...

    • Ben Fisher

      Maybe ( ͡° ͜ʖ ͡°)

  • Rob Cook

    Not to sound like a total newb but has there ever been a good guide written for Greenify? I get the general usage of the app but I'm always wondering if I'm doing it right so I'm sure I'm not using it to the full potential.

  • Roger Siegenthaler

    Question regarding greenifying stuff like whatsapp or hangouts. Will I still get notifications for new SMS, Whatsapp Messages and Hangout messages? I don't really understand how GMS is supposed to tie into this thing and whatnot :/.

    ** I'm rooted if that matters.

    • Kevin Aaronson

      There is an option in experimental settings called telephony wake-up that will allow sms to wake-up up the those apps. So yeah if you check that option you'll still get notifications through those message apps if they are greenified.

      • Roger Siegenthaler

        So essentially if I rely on an app's notifications I shouldn't greenify it? And for apps that use GCM or SMS/Telephone signals I can use the experimental features to make those work (donation package right)?

        • MrIg0Hard

          and xposed framework is required for this also

          • Roger Siegenthaler

            Yep already have that :), thanks :D

        • flosserelli

          Correct on all points.

        • Cerberus_tm

          In Greenify, you can greenify most apps that have the GCM cloud icon. Others apps that need to activate sponatenously (like alarm clocks) will probably not work with Greenify. Whatsapp works, for example. It has the cloud icon. It still gives me instant notifications when I get a message. But Dropbox will no longer automatically upload my photo's if I Greenify it.

  • NM

    With towelroot around, maybe it just uses the same exploit to acquire root on non-rooted phones?

  • Alaa Hallaq

    I must say Greenify is a must have app in all my devices.

  • Bob’s Bilderbergers

    This is game changing

  • dude

    So awesome.

  • jstnbsn

    Maybe it just uses the hidden app opps functionality

  • Big Tony

    I'm still a big fan of Adaway so I still must have root. I use Greenify but have found it less necessary to Greenify as many apps as I use.

  • Nathan J

    The biggest advantage to rooting is still ad blocking. Ads on a 5" screen are simply not acceptable. I will buy premium versions of programs when offered, but when not offered, I don't magically grant permission to display ads. It's a non-negotiable point with me.

    Xposed Framework is another advantage. Greenify? A good ways below that.

    • Somnambulator

      I've had greenify installed for about 6 months and havent noticed any differences. I have a G2 so i already get 30 hrs per charge with bluetooth on all day for pebble and car (disable bluetooth and i get 40-50 hrs depending on use). I dont think i have it managing any apps right now.

      regarding root, however...AdAway and Xposed are absolute necessities for me. Ad blocking is a way of life and Xposed allows me to almost fully customize my OS/GUI without all the hassles of finding a 100% stable custom ROM.

  • http://mobers.org/ psydex

    I don't have this Automatic Hibernation option

  • Josep Reyes

    ive had great battery life ever since i installed this app, so it definitely a must have app.
