Fix Battery life and memory "leaks"

I am now on 25 hours without a charge and still have 65% battery left. Previously I couldn't make it through the day without hooking up the umbilical cord of life. I used to clear apps regularly with the stock task manager but would start out with 150MB free after boot and by the end of the day could not get better than 80MB free. Everyone was crying memory leaks. These are NOT memory leaks but errant programs that cache behind trhe scenes draining your battery and stealing resources. They are also immune to the stock task killer.
I found these bad bad apps by installing Memory Booster Lite from the market. After getting a 0 applications closed I went into the Task Killer in Memory Booster and found a bunch of apps loaded into memory still! Things like Google + hogging 28 MB of memory! There was Amazon Appstore, Maps, Facebook, Beatiful Widgets, Email, Telenav, Netflix, logsprovider....all immune to the stock task killer and slowly eating memory during the day as they load. I killed all the ones I recognized (no com.XXXX stuff) and then checked back in a few minutes to see what would reload. Google +, Beautiful Widgets, Facebook, Maps, and others would reload. Using the paid version of Titanium backup I froze apps like Google +, Maps, Netflix, and others that I don't use daily. You can use other apps for this like Autostarts. I deleted apps that are not worth my memory and battery power. I also set all syncs to manual and keep the display down as low as I need to. The results were tripling my battery life. I also stay on Wifi as much as possible and as soon as I get off XDA App, Tapatalk or any browser clear it with the stock task killer. I always have about 140 MB free now.
Your mileage may vary. The display is the biggest battery killer so if your a gamer, or spend hours reading, don't expect a lot of improvement from this but you will see some. I hope this helps battery life and memory leak myths for some of you.
The important thing in this forum is to have fun and help others.

I'm not trolling, and you do have great suggestions here. I just wish there were some easy way to get an entire day of full use without having to get an extended battery while using the epic to its full potential. I like autosync, adecently lit screen, and my range of Widgets which I use daily. Too bad I can't go more than 16 hours with everything on. I have tried at one point most of your suggestions, and it did greatly improve battery life. I suggest anyone at least give it a shot and then slowly turn back on the things they must have, like gmail sync or haptic feedback.

Blankrubber, this is a good place to add on to what I just found. The key is to see what else is running that is immune to the stock task killer. I never knew how much Google + and Maps were killing my battery. I got rid of my extended battery long ago but now I am sill amazed. 29 hours and 52% left. But the key when you say using it fully is limiting display time and intensity. No matter what that is the biggest drain so if you are glued to your phone for over 4 hours it will always be tough to make it last. Phones that used to be just phones could go days without charge. Now they are little computers. Think...laptops only go about 2 hours runtime without a charge and those batteries are a lot bigger.

I use Bloat Freezer myself. It shows whatever is running in the background highlighted in gray. Google+,Maps, the others Kenny mentioned are the usual suspects. Doing what Kenny said will help out for sure. Yes, its annoying we have to do this to extend battery life but some apps are always at work. Memory Booster is pretty good. Viper baked it in a ROM a while back. Its definately worth checking out

Thanks John, hard to keep up on all these apps to help manage apps and memory. Will have to check out Bloat Freezer. Hope there are less steps than Titanium to unfreeze.

I highly recommend Autokiller Memory.
After reading the dev's page and all he found I installed the app and after setting it up, its maintained my memory free of immune apps and battery life us off the hook!

If something is just sitting in memory why would that have any effect on battery life? It should actually improve your battery life cuz then it just loads the app from memory and not a full re open of the app. Now if your saying that these questionable apps are just running processes then yes that would have an effect on battery as it is just sitting there doing something. But back to the memory side of this. Memory is used in all devices to take some of the load off the processor to make it load faster. It is there for a reason every device would not use memory if it was not efficient at loading apps and saving battery.

But if you only use the app once a week or so why waste those resources or the initial load time. If it sits in memory and another app needs that memory the processor uses more power and battery swapping apps in and out of memory needlessly. My phone is super fast and running 32 hours with 46% left. I can't put up a better argument than those results. Memory swapping is bad on battery it seems.

Whatever dude. Look at my posts count and thanks count. Got this phone a week after it came out in September and never could get better than 16 hours life out of the battery. I do a few simple things as posted and am at 38% with 32 hours. Obviously you are the one without a clue. Troll out of my thread if you have nothing constructive to add. Believe me or not I have nothing to gain by posting this.

I've been around the Android platform for more than 3 years. I've pretty much read all google has shared with us (the Military) for application development and I do agree that there are dormit services that hog up your memory / battery even when your not using the phone.
I agree with this dev and his tool: http://andrs.w3pla.net/autokiller/details
I think that he nailed it when he found out how did Android manage memory and the determination it takes in order to "kill" what you don't use.
Now... Do you care to share what you know about the subject that we don't, in stead of just coming bashing and leaving?
This is a forum, we are more than open to debates here.

the v6supercharger fixed these issues for me. also if you use go launcher, there is a tab in the app drawer of running apps which you can close with ease!

+1 for V6, im usually at 250mb free ram consistently, while closing NOT A DAMN THING

For that basher out there, I am sorry if I don't spend hours watching porn on my phone for you to really judge battery life but here is the pic:
And I may not be able to code Android but I am familiar in C++ and CPU usage and how much you lose by not having available memory to swap programs with.

Nice. That was my issue though is that some of these memory/battery killers don't show up in the launcher's task killers. Google + and Maps never show up and get stopped and continue to kill the battery getting data behind the scenes because Google wrote them in that way. It is important to at least check if you have bad battery life what else is running with a good task killer like Memory Booster Lite.

i think the best solution for battery life is autokiller, v6 script and titanium..the stock gingerbread task manager aka (the running services in settings) isn't that great...when i was on eg22, i noticed it displayed the wrong amount of ram left and didn't display every single app running in the background..autokiller is able to see every single app running in the background but never kill the programs with (com.google and android.process)...I only kills apps i use like engadget and pulse..when u exit these with back button, they always stay in the background and use autokiller to make sure it's completely killed...never set any task killer to autokill apps, that will drain your battery faster...and they are some annoying 3rd party apps that always run in the background since they are not coded well (imo)..for example, i froze the script manager with titanium after i implemented the v6 script because it kept restarting itself all the time..i suggest people follow RandomKing's tutorial on how to extend battery life, it helped a lot..http://forum.xda-developers.com/showthread.php?t=1106524...i constantly have 150 to 200 ram free with im not running any apps..im on eco5 aosp rom with eco5 (eg22 and eh06 are not stable enough for me)

To be honest, I think you're overestimating the effect these task killers are having on your phone.
Your graph looks very similar to mine when I'm using it moderately, and I haven't installed any task killers. (And, yes, I've got the same Maps, Google+, etc apps on my phone). The only changes I've made are:
- Turning my screen brightness all the way down.
- Having very few non-push syncs.
Today I'll be using my phone a lot as a camera, but I'll try to remember to leave it off the charger one day this week so that I have a power graph that lasts longer than 18 hours.

[BATTERY] My battery setup is doing miracles

I've been researching extensively how to improve my battery life on my Android phones and I believe I've found an amazing setup for the Atrix. My phone has been disconnected for 3:15 and I'm at 91% right now with moderate use. It used to burn about 5% an hour before with NO use. Yesterday, it lasted 14 hours and I still had 20% left when I went to bed.
Aura 1.1.3 Debloat #7 ROM
This ROM seems to be the lightest one I've tested. It's only 150 MB and very fast.
SetCPU
I set up a profile to underclock the processor all the way to 216 MHz when the screen is off. The processor is running at 1.1 GHz max. I haven't tested underclocking it to 1 GHz or 900 MHz. I'm sure that would improve the battery life even further and not have a huge impact on performance.
Battery mode (Android settings)
Obviously, it's on maximum battery saver.
General settings
I set the screen timeout to 30 seconds. Maybe 15 seconds is too short for you as it is for me, but that would save some more juice.
Every other battery-killing feature is on, like wifi, GPS and sync. I don't use task killers anymore and found out that my battery life actually improved a lot after I ditched Advanced Task Killer.
I just wanted to share this with the community. I hope it helps you. Any suggestions to improve it even further are very welcome.

Yeah task killers are pretty much useless, watchdog is a wonderful alternative.

Interesting and thanks for sharing, but...
I can get almost the same results by using any other ROM without SetCPU and just using Max Battery Savings but I'm not interested on that setup because I need to have PUSH email all day.
Maximum Battery Savings makes push emails useless, and for a device that's supposed to be "connected" push mail is a must (at least for me).
Unfortunately, push mail is what kills batteries, specially on 3G/4G.

My phone was maximum battery savings one time for some reason. I didn't do it. But for some reason, it was seriously draininng my battery bad. I think i was on 2.2/froyo before i unlocked so i don't know if that had anything to do with it. I do know, i haven't had reason to try it intentionally since my battery is great overall. It does help since atnt turned up the juice on the 3g and called it 4g reception has been very satisfactory lately helping power consumption by not having to look for a signal as often.

Exactly! When the phone switches back and forth 2G and 3G/4G it drains a lot of power. So it too depends on the zone we are in at the moment and that's one of the reason we see a lot of different results among users. Of course, phone and app/game/internet usage style also counts.

I think a lot of people don't realize that terrible reception can account for terrible battery. Often we don't get that feedback when people are whining about battery. Also, lots of the people whining about battery play lots of games, and some of those games that put the gpu through it paces suck up juice faster, but the user is not realistic about that either and expects battery life of a phone that is used lightly.

Yay for undervolting

not "killing" aka "ending" or possibly more familiar "closing" your running apps.. that's like, like if you log into your windows box and you don't have the "X" buttons on the window caption bar.. you just leave everything that you run running until you shutdown..
before you even try to retort, obviously there are exceptions. in windows explorer.exe runs endlessly until you shutdown. on your android device that's the equivalent of your preferred launcher.
what else.. msn? the equivalent of your favorite sms app. facebook and notifications? similar to that browser you keep open with 5 or 6 tabs swiftly consuming your precious processor.
i'm not sure an argument even exists. "task killers" has "killers" in the name which naturally has negative connotations. call it a task manager. windows has a task manager.
other than that nice tips

I am stock everything.. even launcher
3hrs 14min screen on time
~12ish hours off the charger
still says 50% battery. which means 50%-59% on motoblur
pretty darn good eh?

Don't understand the point you were trying to make. Are you saying killers/manager is worthwhile or were you trying make a worthless point about the names?
Anyways task managers are worthless. A good comparison to make are mid/high end laptops and their ram. On a forum I frequent, users were comparing their battery runtime with similar setups. Some were getting extra ~hour or so than others who couldn't figure out why they were getting shafted on battery. Some people don't realize that 4 dimms of ram consume twice the power of 2 dimms of ram no matter the gb of x amount of ram. Thus its better to have 2 dimms of 4gb each than it is 4 dimms of 2gb. The ram consumes power whether you use it or not if it is connected. The 1gb of ram in the atrix consumes the same amount of juice whether its holding 300 mb of data or 800 mb of data. Whether the cpu is computing with something active or not in the ram is what's relevant. Task managers only help when you have a rogue app. Id rather uninstall it then deal with a poorly written app.

Although that may be true for windows computers it its not with Linux which Android is based on. I know that there are virtual machines and all that jazz for the apps but the core system is all Linux and it's even optimized for battery life so when you press the home button yeah that is still running in the background but if you ever need to use that ram it either clears that app from the ram or (based on the app) kills its altogether. And like someone else said ram uses the same amount of power weather it's being used or not.
Also if you're using well written apps then they shouldn't be using any CPU in the background.
If there is some app that's hogging CPU in the background then you need to just uninstall it. Task killers especially auto task killers are actually using a lot of your CPU constantly checking for apps that are using too much ram but Android already does that automatically.
tl;dr
Linux can manage its own ram without you and for the love of God, stop using task killers they're making everything worse.

i was defending their usefulness in general not so much their effectiveness in battery preservation. probably the wrong thread. if any its minimal.
i'm talking about active task management tho. when i'm done browsing the web and want to fire up pewpew for some old school polygonal destruction i kill the browser entirely. i guess its really based on the type of user you are whether or not benefit is to be had. some people are active while others are standby

Sure, it depends on how you use the phone and the strength of the signal you're getting in your area. Would you guys just turn data off in bad signal areas to save battery? How would you handle that?

This is what happened. My battery is doing amazing. I changed the battery mode to Performance during the day and I still have 65% after 12 hours. Not bad. It's about 2.9% an hour. The display was used for a total of 2 hours and 10 minutes.

Battery life posts are useless unless we have some kind of standards during testing.
Like setup your system and then a 15min phone call, 1 hour of video/ ect.. same call.. same video same ect .. ran on each battery setup will give a truer idea on what saves battery the best.
This whole .. it was off charger for 5.33 hours and I used it alot and its at xx% doesn't hardly mean anything.. how much use is alot? How much is little?
Need some kind of same standard test that can be run..

nice to know

Mostly its not about the ROMs you use, but the Kernel or Baseband (Radio) firmware.
At least for me it's been much better than with the original ROM.
Also you must take into consideration other factors like type of use, voice/data signal quality on your area, and many other factors.

CPU mamangement n Note

So i am curious to know does any utility working on Note, that improves performance of Note.
I have installed
1.Set CPU - really i dont find any markable improvement
2.Auto starts - It stops loading some SF on starts definitely, but what? does it has any outcome?
3.RAM manager - My Note have MAY B slight more free RAM, but again does it improve performance?
Really telling i feel all above procedure giving me placebo effect not more than this.
B'coz when i compare it with stock, hardly i can feel difference.
Sure these have marked effect on low capacity RAM devise. when there is consumption of RAM > 80 always remain. But In case of Note, I think it is useless.
Share your review please.

Seriously you don't see the advantage of this?
Not just giving you RAM which benefits are vague. Depending on your use. When the blocked app is not is loaded.
As well as you stop a program from loading, which might ask for sync, wake up the device etc.
Its an alternative to Tits backup Freeze. Except you still can call up on the program with the allowed actions.

I agree it stops loading blocked application, it may released some RAM too. But what i am asking is after releasing of that RAM, does it improves performance?
b'coz Note have alwyas remain 200-300 RAM free, if it is 300-350MB then does it have any outcome? really I dont see.

Did you even read what I wrote .
It stops the program, like the tits freeze. the program won't run.
like for example you stop with this the samsung auto update.
Means it will stop syncing. Eating your battery.
Again saying it. Its like a safer way to freeze an app...

With Autostart you reach better battery stats and lower RAM usage due to blocking/freezing the apps.
They won't start at the beginning and if they aren't loaded, they aren't in the RAM and then you have low RAM usage.
I don't use Set CPU, because the Note is fast enough and doesn't need any overclocking or undervolting.
I use Battery Monitor Widget Pro to see how the stats of my battery are, i can see the full time and when it goes to deep sleep.

No problem here with deep sleep and setcpu.
Gesendet von meinem GT-N7000 mit Tapatalk

With my last rooted phone, I diligently went through every single app that started up without my say-so. You can disable every event they respond to. It is a lot of work, but satisfying to the OCD child inside.
There were dozens, all popping up any time they wanted and eating CPU cycles merrily. I did get more RAM and battery doing that. I will do the same when I root this mother.

Setcpu is working beautifully. No issues with deep sleep whatsoever.

It's true, setcpu working perfectly

I use Tegrak Overclock instead of setCPU because it allows me to overclock GPU as well. Overclocking gives me better experience in gaming and smoother interface.
Autostarts gives me better boot times and gives me control over apps. I like apps to run when I want them to run. Why would I need my car fuel management app to run in the background most of the time of I use it once a week? What kind of a dimwit had that idea? It has nothing to do with freezing apps (except that they don't run at boot in both cases).
RAM manager is my favourite snake oil. According to nearly all the experts around it does absolutely nothing except killing my battery. Somehow I like the way it's been kiling my battery for last 2 months and I'll leave it that way. I don't care about the mechanics of it - simply put since I've installed it I experience less laggy moments in UI (ie. when i press my back button 78906 times to go back through several apps) and the effect of my Note getting sluggish after a day of use is gone.
By the way, I've been wondering - if the famous Android memory management is so perfect - why is it being tweaked so much in so many custom ROMs? And this is what RAM manager really is - set of tweaks packaged in a convenient app, not a task killer.

I use Autostarts religiously. Just becareful disabling system apps.

I won't enter this semantics argument with you or anyone else. You know exactly what i meant.
The point was, don't bash a perfectly useful app when YOU'RE the one to be blamed.

But this is the very nature of overclocking. When it goes wrong it goes wrong - reboot or pull the battery and choose some other parameters. If it's not OK with you don't do it. Why blame an app which is simply a tool (just one of many, I had the same problem with Tegrak several times)???

Android Task Killers Explained: What They Do and Why You Shouldn’t Use

Android task killers improve your phone's performance while also boosting battery life—or at least that's the much-debated promise. Here's a look at how task killers actually work, when you should (or shouldn't) use them, and what you can do instead.
A task killer is an app from which you can (sometimes automatically) force other apps to quit, the hope being that the fewer apps you have running in the background, the better your Android's performance and battery life will be. Not everyone agrees with this premise, though. The argument about whether task killers are effective rages all over the internet: Android forums are full of threads with constant bickering and conflicting anecdotal experience, making it difficult for most users to make sense of the situation.
Below, I'm going to dig into the truth about Android task killers: that apart from maybe some older phones, Android manages tasks fairly well on its own, and how task killers present quite a few problems. I'll also take a look at the rare occasions when they're useful, and offer some alternatives you should try to improve your phone's performance and battery-life quirks.
Before we dive in, here's a quick overview of how Android handles process management by default.
How Android Manages Processes
In Android, processes and Applications are two different things. An app can stay "running" in the background without any processes eating up your phone's resources. Android keeps the app in its memory so it launches more quickly and returns to its prior state. When your phone runs out of memory, Android will automatically start killing tasks on its own, starting with ones that you haven't used in awhile.
The problem is that Android uses RAM differently than, say, Windows. On Android, having your RAM nearly full is a good thing. It means that when you relaunch an app you've previously opened, the app launches quickly and returns to its previous state. So while Android actually uses RAM efficiently, most users see that their RAM is full and assume that's what's slowing down their phone. In reality, your CPU—which is only used by apps that are actually active—is almost always the bottleneck.
Why Task Killers Are (Usually) Bad News
Apps like Advanced Task Killer, the most po****r task killer in the Market, act on the incorrect assumption that freeing up memory on an Android device is a good thing. When launched, it presents you with a list of "running" apps and the option to kill as many as you want. You can also hit the Menu button to access a more detailed "Services" view, that lists exactly which parts of each application are "running", how much memory they take up, and how much free memory is available on your phone. This set-up implies that the goal of killing these apps is to free up memory. Nowhere on the list does it mention the number of CPU cycles each app is consuming, only the memory you'll free by killing it. As we've learned, full memory is not a bad thing—we want to watch out for the CPU, the resource that actually slows down your phone and drains your battery life.
Thus, killing all but the essential apps (or telling Android to kill apps more aggressively with the "autokill" feature) is generally unnecessary. Furthermore, it's actually possible that this will worsen your phone's performance and battery life. Whether you're manually killing apps all the time or telling the task killer to aggressively remove apps from your memory, you're actually using CPU cycles when you otherwise wouldn't—killing apps that aren't doing anything in the first place.
In fact, some of the processes related to those apps will actually start right back up, further draining your CPU. If they don't, killing those processes can cause other sorts of problems—alarms don't go off, you don't receive text messages, or other related apps may force close without warning. All in all, you're usually better off letting your phone work as intended—especially if you're more of a casual user. In these instances, a task killer causes more problems than it solves.
What You Should Do Instead
That said, not all apps are created equal. Many of you have used task killers in the past and actually found that after freeing up memory, your phone works a bit better. It's more likely that this is because you've killed a bad app—one that was poorly coded, and (for example) keeps trying to connect to the internet even when it shouldn't. Any performance increase you experience is more likely because you killed the right app, not because you freed up loads of memory (or, in many cases, it's just placebo). Instead of killing all those apps, find out which ones are actually causing the problems. If you really know what you're doing, you may benefit from using a task killer to stop the one or two inefficient-but-loved apps on your phone.
Note, however, that this is still a contested notion. A lot of developers (including ROM builder extraordinaire, Cyanogen) will not even look at your bug reports if you're using a task killer. In this humble blogger's opinion, your best bet is to stay away from regular task killer usage entirely. If you absolutely have to have that one battery-killing app on your phone, though, kill away—just be aware that when you experience a recurring Android bug later on, the task killer may be at fault. Of course, you can just stop using it to determine whether that is or isn't the case.
With task killers firmly in the better-off-without box, there are still a number of other things you can do to fill the void, improving your performance and battery life
Watch for Runaway Processes: Previously mentioned Watchdog is a slightly different kind of task killer, in the sense that instead of telling you your phone's out of memory and it's time to go on a task killing spree, it alerts you when the occasional app starts eating up CPU for no reason. You can then kill the app with Watchdog and get on with your day (though honestly, at that point, I usually just reboot my phone). If it happens often with the same app, however, you may want to move on to the next step.
Uninstall Bad Apps: Worse than the occasional, one-time runaway app is the poorly coded, always-eating-CPU app. If you find (with Watchdog or through some other method) that a particular app seems to drain CPU and battery life whenever it's running, confirm your suspicions by uninstalling it and seeing what happens. If an app is causing problems on your phone, you're probably better off without it.
Root Your Phone: We advocate rooting Android devices a lot at Lifehacker, but that's because it really is as useful as everyone says it is. You can over- and underclock your phone with SetCPU, install custom ROMs that noticeably improve performance and battery life, and use the ever-useful, crapware-thwarting Autostarts utility to stop apps from starting up on your phone in the first place. Honestly, with one-click rooting apps like previously mentioned Universal Androot available for most phones, rooting only takes a few minutes to do, and you'll be much happier for it.
Update: Many of you also mentioned the root-only app Titanium Backup, which will help you get rid of the pre-installed crapware that comes on most phones, which are one of the worst offenders of phone lag. Thanks to all of you that sent this in!
Seriously, Use the Power Control Widget: This may sound ridiculously obvious, but if you aren't already using some form of the Power Control widget, you should. The things that drain the most battery on any smartphone are Wi-Fi, Bluetooth, GPS, and your screen. Turn them off when you don't need them and you'll find that you can eke out considerably more battery life.
Charge Your Phone: Even more obvious yet rarely heeded advice: Charge your phone often. This isn't as hard as it sounds for most people. While you're sometimes stuck going out for 14 hours with no place to charge your phone, the majority of us spend our days in our homes, our offices, and other places rife with electrical outlets. Buy a few extra chargers and place them strategically around your home, car, and office. Whenever you're sitting around at home or working away at your desk, you can use that time to dock your phone and give it some extra juice without worrying about battery or performance drains. Before I upgraded to Android 2.2, my battery life was pretty awful, but just having a charger in my car and next to my computer made a huge difference in how often I got the dreaded "low battery" message.
Task managers are a controversial subject in Android-land. We've done our research and this is what we came up with, but we're always keen to hear how similar or different your experience is, so share with us in the comments.

Exelent post. I'll uninstall my task killer now, and I'll try Watchdog app to see the the difference on performance and battery life. For example, I have Navigon installed, but always closed, I'm using sometimes. Is that app draining battery when closed?

Watchdog will tell you how much of your cpu a certain app is using. So i believe (pls correct me if i'm wrong) that that would give an indication if it is actually playing a part in draining your battery.

Galaxy note 4 memory

Can anyone of you download advance task killer from the android market/Google Play. Download and could you check how many memory do you have? When I bought my note, I had only 40% of memory available on my phone, which means about 800 MB, and I couldn't take advantage the rest of the 2+GB memory because phone has couple hundred apps preinstalled... Now I started clearing and un installing all these unnecessary apps and now I have about 1.6 GB memory available on my phone, and as a result of that I was able to get two days battery every day. Basically I can't finish my battery in one day regardless of the usage, which is really good....

Haven't used a task killer in a long time. I looked out of curiosity and there is a massive laundry list of extra crap going on.

Thanks for the info. Can you please tell us what apps you were able to remove to cause the excellent battery life? In the order starting with the one that uses the most to least if you can. Appreciate any help you can post from your testing. Thanks

Well, twospirits made this list of all apps https://docs.google.com/spreadsheet...OksNUB7oHFBsI_OoEQHgeGg7_l4/edit#gid=32644709
So what I did is: I categorized my apps in to three categories: 1- Apps that cannot be removed nor disabled, like Bluetooth speaker and etc so kept those as it is.. 2- the second group are necessary apps like Google play, browser sms,dialer and etc.. so I moved those apps to EX Sdcard, the only exception is youtube which gives me FC, so it has to be in the system..
3- the 3rd category is the rest of the apps which I removed from my phone, like S Health knock and other hundreds...
Now I have almost 2gb availabe memory on my phone which I think it's very good, and that's the reason I'm getting one day of very high usage or two days of normal usage....
Please check my screen shosts, almost two days with 5 hours of Screen On time or 7+ hours in one day....

Thanks for the info. I will work on removing apps that I don't use from the list and see what improvement I can get.

Just wanted to explain a few things.
1) moving apps to external SD Card will not free up RAM. It frees up internal memory (/sdcard or /data) but should not affect RAM.
2) unused RAM is wasted RAM. In this case you are saving battery because some of the apps you deleted were using CPU cycles or keeping wake locks for some reason. The amount of energy used to keep an app in RAM may get you a few extra hours of battery life at most. Your biggest 3 battery killers are Screen, Modem, CPU. In that order.
So good job getting better battery life, and I'm going to be using that list to delete some crapware. But your conclusions in why you saved battery life are a bit off.

Ok this is what everyone in this thread should do before they comment on memory usage,
1. N910C or N910F (Snapdragon or Exynos?)
2. Debloat or not, all apps active (stock)?
3. Debloat with root?
4. How much time without reboot, test of memory usage with or without reboot?
5. Screenshots of disabled apps section of your storage
Me,
1. N910C
2. Debloat, disabled quite a bit services/apps
3. No root
4. Fresh reboot, just now, test of memory usage = 1.52Gb only Wi Fi File Explorer in background.
5. Turned off apps,
Please, i know every device is different but try to follow my little Q & A, in order to get a general idea how much memory does you device use.

Pretty much. But coming from the SGSIII. Ive actually kept a lot of Samsung bloat that id usually delete. Mostly because of its features. Ive spared SprintZone even. Just a nice smooth phone overall.

Sir, First of all I'm not a dev, and probably you know more than me about these things but let me ask you this:
Even though I've already deleted unnecessary apps from my phone, but still I was using 70-80% of my phone's memory all the time, and my battery life was one day or less than that .....
I decided to move all my apps to ex-Sdcard which made me using only 30-50%, of my phone's memory and the battery life from one day to two days!
So since you said moving apps to EX-sdcard won't make difference, could you explain to me this situation?
Please go ahead and check my screenshot, I'm watching MKBHD'S full hd video and I'm only using 37% of my phone's memory.
Thanks again.

Were you perhaps plugged into a computer? You lose the ability to use SD Card apps when plugged in.
I'm definitely not a dev, I just know electronics and a bit of basic computing theory.
Using less RAM shouldn't save that much battery. What may have happened is one (or more) of the apps were auto-starting and using CPU cycles to do something not important to you. I'm not sure if SD Card apps can auto start or restart.
Like I said the information you provided is good, just the comclusion of less RAM means better battery is off. Well programed apps should sit in RAM for quick access but not waste CPU cyles on things.

You right, I think maybe EXsdcard apps won't auto start and that's what saves my battery. When I check my running apps I cannot see any user apps in there, no facebook, what's up, Browser or any other user apps, so maybe that's is the case.... The only down side of my situation is that I have to manually open Facebook to see latest notifications which honestly I don't mind it because I don't need facebook and twitter running 24/7?

You should NOT be using task killers on Android! Advanced Task Killer, or any task killer, will shorten your battery life instead of extending it. Android actually knows how to handle itself quite well, and will keep certain things around for a reason. Google created Android and just might know Android a little bit better than those 3rd party app developers.
Also, I see in your other posts you keep calling a micro-sd card an ExSdCard. If you think about it, "Ex"SdCard would actually mean "Previous"SdCard. It's called ExtSdCard, meaning Extended SD card. And FYI, there is no Android Market anymore, it was replaced by Play Store years ago.
