[APP] Greenify *ROOT* - Galaxy Note II Q&A, Help & Troubleshooting

Has anyone tried this app? It's supposed to put certain chosen apps into hibernate, like how iOS's multitasking works.
What apps would be best to put on hibernate? Can we make a list of apps safe to hibernate + save battery life in the process?

242 five star ratings, something seems to be making the users happy. I may try this out, as my biggest drain seems to be background applications, apart from the screen that is.

I tried it and i must say, it's pretty damn good!

Yes we can save a lot of battery

[TIP] Have bad battery life? Here's how to diagnose. (UPDATED 7/29)

Well i been noticing a lot of people complaining (or commenting) on bad battery life on a ROM they just flashed. I decided to start a thread on how tips to improve battery life. It's not necessarily a ROM that gives you bad battery life (specially if most people comment on how great it is)....there might be a few thing you or your phone is doing to cause this.
First: After flashing a new ROM, you will have the worst battery life ever. The battery will have go through a few cycles before battery life will be apparent. It is also worth noting that sometimes a battery calibration will have to be done by either traditional methods or by the Die Hard Battery Calibration Script by Zeppelinrox. (Not sure if it really works, never tried it…..but its worth mentioning)
Second: Turn off unnecessary sync’s in the phone (toggle button) and apps, such as Facebook, XDA (sorry xda), emails…etc). Yes it is cool to have your Facebook notify you every 30 minutes about somebody’s activities, but that takes up power. I am not saying turn off everything, but you have to find your sweet spot about what is to be on.
While we are talking about deactivating sync’s or limiting them, let’s talk about widgets for a second. Let’s not forget widgets are in automatic sync, sometimes you can control the frequency, and they will use extra system resources such as WiFi, 4G/3G, GPS, etc and this means extra battery usage.
Third: Turn off all radio's such as 4G/3G,WiFi, and GPS when not in use. It goes without saying that if you are not connected to WiFi, it is going to use up battery searching for connectivity. Also, If you notice that you lost signal completely while at work or in a building for an extended period of time, I suggest turning Airplane Mode on. I use Airplane Mode at work and my battery drops 2-3% in 4 hours. You can also turn off data (4G/3G) when you phone is not in use by simply turning off the data toggle.
Forth: I highly recommend using the apps, GSaM Battery Monitor, Better Battery Stats, and CPU Spy to monitor and verify wake locks and apps stealing power. I also recommend Eugine's app, CPU Sleep. All are available on the market and also free on XDA, but why not pay the 2 bucks and support the dev's.
GSam battery monitor used to be Badass Battery Monitor (because it was [email protected]) but i guess too many people complained so he changed it to GSam, but it still is the best out there with very minimal system drain. What this app does is explain to you what is using battery and how much. You can see what inactive app is using battery. It will also show you wakelocks, and what apps held your device awake and for how long. A lot of useful info to help track down battery drain.
Better Battery Stats is a more in-depth info about wakelocks from kernel wakelocks, partial wakelocks, alarms (scheduled wakelocks for each app) and so much more. This can be intimidating to look at and read at first, but you will learn your way around it quickly and what it is telling you. It does include a database link to most wakelocks to help explain most wakelocks.
CPU Spy is useful to be to help determine what my CPU is doing throughout the day and shows Deep Sleep which is very important when tracking down battery drain. This is, in my opinion, optional. Not necessary to track down the culprit of battery drain, but it helps for me.
CPU Sleep is a wonderful app designed by Eugine that when the phone hits deep sleep...it ensures all but one core is sleeping until you wake the device. Far as i am aware, it only works for TW ROM's....i am sure he is developing for CM and AOKP ROM's, if he hasn't done so already.
Fifth: Screen Brightness. Now I know we have a huge cool screen and you want others to see it, so you jack the brightness up to 100% or on Auto. The fact is we have a HUGE screen that loves to eat up battery power like it’s nobody’s business. Now I know putting it on the auto selection sounds like a way to sound power. And in a way it is, but you have to realize it takes more power cycling through different levels. I suggest lowering it low as possible that you are comfortable with. I use 20% brightness, and I feel that you use less power than auto because it’s a constant brightness now going from dim to bright and everywhere in between. (-thanks mrrobc97 for the reminder)
While we are talking about displays, mrrobc97(thanks again) also brought up the about turning off landscape views, not to use live wallpapers, and the use of dark wallpapers and themes.
He also reminded me about disabling apps on startup .He and I recommend the app Autostarts from the playstore. I highly recommend this app over anything I used, including Rom Toolbox’s feature that does this. Not to downplay Rom Toolbox in anyway (it is a great app) but I have had bad luck lately with the autostart feature in the past…probably my own fault for fudging something up I shouldn’t have been (usually disabling YouTube is when it goes haywire with FC’s). Autostarts is a bit more advanced then RT’s autostart tool.
Sixth: 3rd party app killers do nothing. Yes they kill everything running on your phone, but the apps you just killed in your background will restart, thus using more battery power to start back up than it would of if you just left them running. This also is the same when you do this in the stock app manager too. (thanks blunified for the tip).
If you have anything to add or correct, please feel free to post and I will add.
Right now i get about 17-20hours on average of battery life on a work day, and 20-26 hours average on a non working day.

Update 7/29:
Revised my original post and added in tips from members mrrobc97 and bluntified.
I'm not saying you're wrong, but a lot of this stuff is situational. I think the majority of the frustration people have is when their phones are draining quickly while using basic functions; the reasons why we buy these phones in the first place.
I've tried every gimmick and gadget to get better battery life, but I can't seem to reliably get my phone to drain at much less than 10% an hour, unless I'm just straight up not using it.
I was getting 7-8% on Darkside v8, but since he's taking a break from it I decided to try some other stuff out. That's the best I've had, coming from Juggernaut and DW before.
Same deal with cm9 and AOKP, about 10% an hour with a busy work email, one Gmail account, fair amount of texting, checking my RSS feeds and XDA every hour or so. Screen on automatic brightness.
It's not horrible, but it's not great. Maybe I have a wonky device? Either way, I like having what I use always available, and if this is the battery life trade off for that, I'll deal with it. I live and work in Manhattan so it's not like I'm ever far from a charger.
What am I gonna do, get an iChick phone?
Hell no.

I understand what your saying. The point i was trying to get a lot of people was to realize that a lot of wasted power loss comes from apps not allowing the device to sleep as it should. I remember watching my phone draining 20% an hour in airplane mode come to realize later that i had to many widgets refreshing, all sync's on and updating every 30 minutes with other apps constantly active not allowing the phone to hit deep sleep at all. I totally agree about a battery should last a longtime without having to check for wakelocks and whatnot. I think the blame comes from a mixture of poorly written apps, android power management system that's not working efficiently as it should, and a battery that should of been a bit bigger.
For sure. People need to have reasonable expectations though. If everything is light up like the Vegas strip your phone isn't going to last very long. But if you have everything minimalist and turned off you have an expensive pet rock. I think the best advice you can give is the self diagnostic stuff so people can examine their habits and figure out a fun to battery balance that works for them. The programs you suggested are all good ones that have helped me out at various points.
I've almost chucked my phone out the window because of the damn media process always running ffs.

No not saying that at all. But do you really need to have everything on a half hour sync? Actually just a manual sync would greatly improve battery life.

I need to throw in Autostarts app. It enables/disables an app start-up on system boot-up. It also enables/disables an apps start-up when certain events happen (like when a charger plugs in it will start-up a certain app on when an app makes another app start-up that you probably don't need on). It really needs to go on your list Biker.
Another thing you forgot to mention is the screen brightness and your choice of the background theme or wallpaper. OK common knowledge you should know by now... BRIGHTER SCREEN = HIGHER BATTERY CONSUMPTION... don't keep it the lowest cuz you're going to end up switching it back and forth depending how bright your surroundings are thus wasting more battery...just keep it on AUTO! Also...do you really need that snow landscape for your wallpaper? Do you have to view your kids everytime you wake-up your phone?...NO?...then find the darkest coolest wallpaper you could live with. And last go through all your apps and (if the option is there) choose the darkest background theme available, like for the mail, sms/mms, or tapatalk app.
...on another note...YES, I will agree that in order to get maximum life from your battery you will have to sacrifice alot of the stuff that makes your smartphone cool like the amount of widgets you could be running, bright ass screen settings, or that live wallpaper you're running. You also sacrifice instant use of your phone (i.o.w. instead of checking your Facebook widget to see what's up you have to---open notification toggles - enable data/wifi - go to app drawer - open Facebook app - wait for it to load - then see what's up). All that coolness its whats sells a smartphone (see commercials) but it comes at a high battery-drainage price.
My wife has a t989 like me but white and so does her lil' sis. Her setup is identical to mine for the exception of a few apps and that she has a purple version of my Blutiful theme. She's always telling me (or talking **** i.m.o.) about how on her lil' sis phone you are able to view Facebook, YouTube, and News right on her screen (i.o.w. widgets) and not hers and I tell her its not gonna happen cuz I don't want her *****ing later on about how the "phone" sucks cuz the battery lasts half a day JUST like I always hear her lil'sis *****.
...so anyways the point I'm trying to make is that you have to make that choice (coolness vs battery life) or try to find YOUR sweet spot between both of them. Another thing you could do is have a few spare cheap batteries from ebay. They work almost as good as the OEM and for all we know they probably come from the same place and just slap different labels on them. Buy a cheap $3 battery charger also and have them charged and just keep one at home/car/work like that you could swap if the need arises. I also bought a few cheap home/car phone chargers from ebay and also have them at home/car/work. They have all worked good for me w/o any issues. You might catch me with my pants down one day but you will NEVER catch me with a dead phone I promise.

Another thing to note is, using the "kill all" button on your task manager will use more battery. There are apps that need to run in the background, when you close it, it will have to reopen itself and use more battery power.
Altogether, task managers are no good.
Thanks mrrobc97, I forgot about all of that. I'll add in when I get home. I used Rom toolbox to kill auto run apps a while back and messed something up somehow. Had to reflash. What app did you use?

[Q] Dose installing many apps drain the battery more quickly

I have heard somewhere that installing many apps can drain the battery more quickly
I just want to know wheter or not installing apps that are not running in the background drains the battery?.
Thanks.

Not if they are not running in the background
Some people have installed more than 300 apps (user apps)
scribbled from my note 2 (N7100)
It's no different than your computer. You can have 50000 apps installed, but only the ones running consume active (ram, battery, network) resources.

I would love to help you, but help yourself first: ask a better question

Be aware though that many do run in the background even if you haven't run them.

In General Yes, but I'd say depends on the apps, if there are 200 quality apps, (however I don't know how many are there in Play Store), and you've not turned on the background data for them, then it might not drain much. But if you've even 5 crap apps installed then they'll be enough Culprit to hog the juice more than those 200 apps.
In short, DO NOT install crap apps, do not install whatever you see. Read user reviews, see ratings, then decide. I, for me, think 3 times before installing one, even if it comes from a Top Developer tag.
Yes it does take more battery. So install the apps which you are going to use.

It totally depends on applications you have installed
If you have hundreds of application and they don't autostarts or have no sync function and just occupying storage, it won't drain battery, in usual course i do have 150 user application installed but hardly it even drains recordable juice except some of it requires auto refreshing and sync
Sent from my GT-N7100 using xda premium
There are application that can disable the apps you've installed from auto starting or running in the background. Usually the biggest culprits are the free ad supported apps that tend to randomly call up even when the phone is in sleep mode. There are many ways to stop it from happening.. If you can pay for ad free app then go for it otherwise a lot of 3rd party apps will allow you to disable those features. I don't understand why someone would install 200-300apps in the first place when you only end up using less than a quarter of those. I guess its that "you never know when you're gonna need it" habits.
Sent from the Rabbit Hole
There are a number of apps which do run in the background, even when you don't manually run them first. Applications can register receivers to trigger at various events (such as boot-up complete, call ended, etc) and complete tasks in the background, or register themselves as services. You can check these with an autostart app, or I use ROM Toolbox (https://play.google.com/store/apps/details?id=com.jrummy.liberty.toolboxpro&hl=en - there is a free version available too).
On top of that, apps can also run scheduled tasks which can wake the phone out of deep sleep in standby, which can cause additional battery drain, through either CPU or network usage.
Unlike iOS which kills most background apps after a couple of minutes, Android apps can run indefinitely in the background, unless of course they are killed by memory management first.

It keeps apps from waking the device and running unnecessarily in the background. I use it for Maps so it isn't eating up resources and draining my battery. Technically you should see better battery life if you hibernate the right apps with Greenify.

You're comparing apples to oranges there. Those two apps don't even remotely do the same thing. Greenify's sole function is to shut down those pesky apps that think they deserve to run services in memory when they really aren't needed. Many apps/games do this. It's gotten to the point of stupid and, imho, is the fatal flaw in Android. They need to implement something to end this behavior.
Say you install ten games and each one is coded to run a service in the background (either to collect data about you or just because they can). Now your phone is sluggish and runs like crap because you no longer have enough memory left over for your phone to cache previously opened apps. So now when you open an app, it has to load from scratch. And now when you open an app, android has to knock out one of those services to make enough room to load that app. But guess what, that service is coded to auto reload itself and to make room for itself, so it must knock out a different service to make room for itself. Now that service that just got knocked out wants to reload but has to knock out another one... and the cycle goes on and on. Services that aren't needed reloading and Android kicking the others out of memory in an endless battle for memory.
Now this scenario only happens in low memory situations, but it really doesn't take that many needless apps running services in the background to put the Galaxy Nexus in this situation.
This is why you see so many Android phones that just run like garbage even when they have a good processor and memory. And this is one of many reasons for crappy battery life.

Greenify!

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).
ROOT is required. If you are experiencing hibernation issue, this may be caused by your root management app (e.g. "SuperUser"), please try installing "SuperSU" instead.
here is the link
https://play.google.com/store/apps/details?id=com.oasisfeng.greenify ( you can download it from attachments too !! )
There is also a donate version which lets you put system apps for hibernating as well!
Here's the link for that..
https://play.google.com/store/apps/details?id=com.oasisfeng.greenify.pro
Give it a try people and don't forget to thank the owner and me if I have helped..
OP I have removed the apk because the developer only wants it to be downloaded from the playstore (yours was the old version anyway). Here's the link Please don't do that again. http://forum.xda-developers.com/showthread.php?t=2155737
Cool app! Missed this one until now. I'm wondering if there any advantages/disadvantages to "Greenifying" apps compared with "Freezing" apps with Titanium Backup. It seems that Titanium's freezing requires more work on the user's part. Their widget that freezes/unfreezes and launches and app is very similar. The difference is that I have to manually REFREEZE the app when done. Is this correct? If so, this is a wonderful app. Still testing...just installed. THANK YOU!
You are correct! I used to use titanium b/u pro.. But like u say, it requires much user attention and input. I much prefer greenify, and I seem to get better battery life with it too (likely because of the automation, thus less screen-on time = better batt life). Not sure if it gives better performance, cause I don't push my phone very much, and it was already fast as hell with tbp.. I'm running soa b4 right now, previously jmt6 worked great with both. Hope this helps

[Q] RAM is at 2GB of 3GB ??

I have noticed that im using up 2gb of ram. But i have only downloaded a few apps. No games. All the stuff i had before. My old phone was a little over 1gb total. Is this normal. Does the phone uses a lot of ram out of the box. Im thinking of rooting just so i can free up some ram. Not sure if that is possible. Im coming from a galaxy and very happy with this d851 g3.
Anyone having a memory problem ? Issues? What can i do?
Android always runs while using up as much ram as possible. Thats normal, if your phone had 8gb of ram, most likely it would also be using most of it up.
Makes app switching faster.......

Not completely true. I disabled most of the T-Mobile and LG crap on this phone and it's still using the same amount of RAM. It's Android's memory management.
I bet if the Android team could go back in time in the early days of system development they would have probably removed the ability to see free ram. So many people get caught up in free ram when the phone is using the available ram to the best of its ability.
Windows does alot of the same as well. Even though if you go into task manager it shows free if you actually look at your system resourses it shows alot of it is taken.
Unused RAM is wasted RAM.
Not sure about the whole 2g for 3gb thing but your system need all the rams it can use to keep your phone running smoothly. If you use ram cleaner (so they are call) you will notice your phone goes through a gitter before it it can pick up again. You look 5 minute later, its like you never clean anything.
and tmobile is surely 3g
Free RAM is wasted RAM.
Android uses RAM differently from say Windows. Android will use as much ram as available and when it needs more, it will free it up as needed. This is normal.
So yea i installed greenify and it made a **** load of a difference because i have like 40 games and a load of other apps. I have less than 1.5 gigs used now. And my phones way smoother and batterylife is good again

Don't worry you're about to see that battery life drop like a rock. Constantly killing apps will kill your battery fast. Greenify is a nice app if you have a crap phone but your G3 was made the way it is for a reason. What you think is smooth and fast is actually hurting your phone. Don't believe me, Google it and do some research. I do not recommend anyone using any format of task killer or ram optimizer on a phone that is current with the times.
Do I think the phone has issues. yes. When using it the apps don't close when ram is needed. Only fix is a reboot or kill the app but at times that does not work

Don't worry Jammol doesn't know what he is talking about. Greenify doesn't hurt battery life and performance like a task killer because isn't a task killer. It is completely different. I agree that task killers should be renamed to battery/phone performance killers but Greenify is very different.
First of all it requires your phone to be rooted. Assuming that it is, it uses special permissions from the rooted device to essentially freeze the app unless it is opened by the user. For example, I use facebook but only casually. I look at it once every other day or so but have noticed that the push notifications and messenger uses a lot of battery because it does a partial wake everytime it pushes a update which activates the internet and cpu.
The solution is to "Greenify" the app. The app still loads normally when I open it up although, because it is not in the ram, it likely takes slightly longer to load. Once it is opened, I can use it like normal and I get push notifications again until my phone's screen goes off. Once the screen goes off, facebook and all the apps that I "Greenify" are flushed from the memory and are banned/essentially frozen until I launch the respective app again. The only drawback to this is that you essentially never get push notifications for the apps but it saves a lot of battery if you pick the apps that you don't care much about/rarely use.
So greenify does work really well. Today my phone had 17% left. I it had 16+ hours of battery time total. I got 4.25 hours of SOT with sync on (with 3 email accounts getting push notifications plus other apps), GPS high accuracy, LG health automatically recording my exercise, and 1 hour of navigation with Waze. Basically I used my phone how I wanted and didn't micromanage my battery usage throughout the day at all.
I used 3 battery saving tools. 1. ART 2. Greenify and 3. Custom Kernel V002 from KAsp3rd. These three are very powerful together.
I hope that helps someone!
ART

Don't worry Jammol doesn't know what he is talking about. Greenify doesn't hurt battery life and performance like a task killer because isn't a task killer. It is completely different. I agree that task killers should be renamed to battery/phone performance killers but Greenify is very different.
First of all it requires your phone to be rooted. Assuming that it is, it uses special permissions from the rooted device to essentially freeze the app unless it is opened by the user. For example, I use facebook but only casually.

Out of curiosity, how are you using art with xposed? Greenify uses the xposed framework.

I am not using xposed. Greenify works just fine for me without xposed. If you want some of the more advanced and experimental features, you need xposed but the basic functionality does not require it..

I know what you mean! This is just the latest skirmish in the never ending war between features and battery/performance. I can't wait for Android L to come out because this particular battle will end (xposed will support android L which uses ART exclusively) but the war will rage on..
