ICS task manager... too much?

So me and my buddy both have a Gnex...
I tend to not really use the task button on the nav bar too much to swipe away tasks.
My buddy on the other hand likes to kill apps off EVERY SINGLE TIME he leaves an app. And i mean EVERY time, as soon as he leaves it he swipes its ass.
I think thats a bit much.
Ive always been under the impression that any kind of task killer can do more harm than good, as it slows things down when you reopen an app as it has to load it from scratch again.
My friend argues that your supposed to do it because thats the the button and feature is there for.
I would have thought that it was just there for in case you want to manually free up ram for what ever reason, or quickly jump between apps.
So whos doing the right thing and whos doing the wrong?

there is no right or wrong for this.. its all personal preference
i usually just keep it there until i kno i have reach like 10+ apps, then i just swipe them away cuz i dont want my list to be that long...
but when u say close every app every time.. i only do that when i kno it keeps running in the background sucking my cpu and battery ex. Facebook app
then i will swipe away every time i dont need it, while others i just keep it there

"task manager" its not a good definition for what it does
in real its show u the list of the last used apps and when u swipe away an app, u ONLY remove it from that list...it doesn't ( correctly ) kill anything
the real important thing, is that when u want exit from an app then press the back button to leave the app...the home button instead leave the app "running" in its state

swiping away from multi-tasking UI DOES kill the app.. or u can say kill the activity, but if the app has a process, it will still be there.
but it definitely kill the app activity

From a simple test it doesn't kill any app for me.. try checking the apps running with quick system info or a similar app

its been discussed in here xda (try the search button), AND from google android developer (her g+ post)
IT DOES KILL believe it or not

its purely personal preference when it comes to swiping away the tiles/icons/whatever, but he needs to realize that all he's doing is slowing down the resume/relaunch times of his apps, not to mention wasting minutes of his day swiping them away for (effectively) no reason. He's not going to see increased performance or battery life from constantly OCD closing the apps.

That...
And if there is an obnoxious app that he's killing...one that auto-starts itself again...
It'll waste battery as it restarts.
(These obnoxious apps should be avoided anyway, obviously.)

are we talking of the same thing? pressing the ics built in multitasking button (on a stock rom) doesn't allow u to kill apps, only to remove it from that list

seems like ur trolling more cuz it has been proved it does kill the activity of an app when u swipe away in multitasking ui

edit: there are lots of videos on youtube of people posting it kills from swiping away
showing the difference between pressing home after opening the app, then swipe away, the app has to reload again. cuz it kills the activity

DARKSIDE v7 - Apps not being killed...

I am on TDJ's Darkside Venom v7 and I have looked everywhere trying to find a solution... I don 't know if I'm crazy but my apps (i.e. YouTube, FlipBoard, XDA, Play Store, etc...) won't kill themselves after hours of not being opened back up. They stay in the exact same state I left them when I clicked home or closed the app. I never had this issue before because the Android OS has been pretty good at killing unused apps however on this ROM this hasnt been happening. I am new to the whole rooting thing and have learned quite a bit however still a newb none the less..
I've searched the whole thread however still running a blank...
Does anyone have any advice??
Thanks in advance.

pressing home will keep it open. You need to press back to exit it. The OS does not feel the need to close them because we have 1gb of RAM. You can always swipe the screens from the recent list.

App killer

Cyanogenmod 10.1 has a button on the multitasking menu to do that. But it's kinda pointless except to clear the list of recently used apps. Android, if my understanding is correct, automatically fills the memory with tasks so killing apps is worse than pointless since you're just causing the system to prioritize unused background processes over the ones that you use more often.

You should listen to this guy. I know you're coming from a different OS, so you aren't aware of how Android deals with memory. The system is very good at multitasking. Apps that have been idling in the background will be pushed out and won't consume resources or ramp up your CPU. By killing those apps, you force the system to have to reload and process resources necessary to start the app. Android will keep enough of the resources to quickly fire up the app, but restrict activity so that your battery is pretty much unaffected.
An analogy if you need it: Android will bookmark and close whatever you were reading. That way, you can move the book around or leave it on the shelf and quickly pick it up and continue from the last page you were on. You are requesting that the system instead just closes the book, and buries it in a box with other books, and which is located in the attic. It takes more resources to find the book and locate the page again. Just let Android do its thing. Any popular dev will tell you the same thing.
TL;DNR - Don't use a task killer, you will get far better battery life and performance if you let the system deal with system resources.

Don't listen to this guy. He used the phrase "smart one," which I haven't heard since I was in elementary school (and I thought it was un-clever and uselessly sarcastic then). He also thinks that swiping away apps from the recents menu kills them. This is not how Android works. AOKP devs will not implement a recents menu that actually does let you swipe to kill apps because it's a useless feature that does more harm than good (zero benefit, actually). Just trust that your system knows how to handle its resources.
TL;DNR - Swiping away apps from the recents menu doesn't kill them. Stop trying to kill apps; only do so if they're unresponsive.

If u really want it, aokp has this feature

Let's say I start loading a web page and quickly jump to another app before it's loaded, then when I return to Chrome the page is ready and waiting. Doesn't this imply that apps are not just simply bookmarked and closed, but may remain active in the background? I am asking, not saying btw.

Foreground apps are told that they are no longer in view, but are allowed to keep running if they wish. The OS will stop them if the memory is needed - which with 2GB is not very often on the nexus 4!

So Hung0702 was wrong on the last page when he said:

It seems as though background apps can use resources and may have a negative impact on battery. Now I have got to the bottom of this I also want a clear all button!

Yes, they can keep using resources in the background. However, they will usually not keep the cpu awake unless they have an actual background service, so they will not stop the device from sleeping. As far as I know this is not enforced, but most apps will release the wakelock when told to pause by the OS (because the app is now hidden). This means they shouldn't have much impact on battery life.
You can see what is currently running by going to Settings -> Apps and select the Running tab. The recent apps list is not the same - most will have actually closed when you hid them.

Samsung Galaxy S6 Edge+ Battery Saving Tips

A phone even with killer looks and amazing features still needs a descent battery backup to support it all. In past we've seen that a few tricks here and there always tend to increase battery life. Usually that includes disabling a few apps or features. This thread is for specifically targeting such tips & tricks and sharing it all so that S6 Edge+ can live upto its expectations..

1. To start with, lets get to the list of bloatwares that can be safely disabled.
If any of you own the AT&T version, here's a list you can disable:-
AT&T Apps:-
AT&T FamilyMap
AT&T Hot Spots
AT&T Live
AT&T Locker
AT&T Mail
AT&T Mobile Locate
AT&T Mobile Transfer
AT&T Navigator
AT&T Ready2Go
AT&T Smart Wi-Fi
Drive Mode
Caller Name ID
Mobile TV
Plenti
Smart Limits
Yp (Yellow Pages)
Other Apps:-
S Voice
Amazon (I prefer the playstore version for frequent updates)
Amazon Kindle
Device Help
Live Weather (Yahoo)
Lookout
Theme Store
Visual Voicemail
2. Refrain from using any free application that has embedded advertisements. They tend to run threads in background to load adds and thus degrade the app performance and used data (so naturally consume more power too). Either buy add-free version or find an alternate app for same purpose and without adds.
3. Disable notifications from social media/news apps like Facebook, Twitter, Tapatalk, etc. Although, the phone wouldn't be that smart if all the notifications are disabled, however, keep them at bare minimum. Not everybody would be interested in notifications from all the apps, so spend some time analyzing through all the installed apps and their settings to turn off the notifications for the apps you do not need to get notifications for. There are several apps that keep sending notifications and running a thread in background which again checks internet to load the notification content. An example would be games like Candy Crush or Clash Of Clans.
4. Turn off "Send Usage Statistics" or "Help Improve the app performance", "Participate in improvement" etc settings from the app which sends data from your device from time to time which acts as a survey to improve the performance of the app. Although this is a necessary option for a developer, however, if you do not care about your granular contribution towards further development of the app, try deselecting such options while setting up new apps.
5. Refrain from using external Memory Management Apps and RAM Cleaners. They tend to run heavy background services to detect memory usage and kill applications. Trust me, you would be better without them.
6. Try using black wallpaper and lock screen. Also, always select Dark Mode if any app has theme section. This makes the pixels produce less brightness and considerably save more battery.
7. Keep GPS Location off when not using any navigational/location based apps. When the GPS is ON, there are some apps that tend to acquire a GPS Lock even though they can work without it. Keeping GPS Off will not allow such apps to request for GPS Lock. GPS Locking is a battery draining process.
8. You can use certain tools like Greenify, WiFi Automatic, etc. to automatically manage application states or phone wireless to save some additional battery. Use these only if you are lazy like me. Otherwise you can always manually turn on/off wifi/bluetooth/nfc etc etc. Also, there are tools (like Juice Defender) which can enable/disable data connective at a frequent interval which results in really good power conservation without loosing push notification.
With applying most of these settings, I'm getting 6-7 hrs of screen on time very easily even when I've downloaded 1+ GB data and 40 minutes of video chat (hangout). Not to mention the usual gaming and application usage.:cyclops:
I hope that helps. I'll keep adding if I get any (without root).

Reserved for future use!

I'm sure you mean rooting and installing all sorts of battery saving items/tweaking.
Marely rooting wouldn't bring any difference to battery life for sure!

Just tweak brightness, make sure you getting good signal and use WiFi when available, don't leave Abby of the radio on unless not using it and that shall be good I guess

It's the icon on the lower right corner of the screen that says "Apps". Once you get in there find the app that you want to disable. Long press the icon of the app and drag it to the upper left corner of the screen where it says "Disable". Then when the "Disable" word lights up red just release the app into there.
Check out my screenshot for an example.

Thanks for the listing. I love the new design than S6 edge, hopefully it will last longer as well...

Please tell me a solution if any one knows:
I open facebook and after some time i close this application by click on list tasks soft key and close it. Immediately when I go into setting > application manager > running apps I still see a facebook process running. Technically i guess this should be gone i guess and hence any idea how to clean these which i guess can improve battery life.
Update: If I have notifications turned on in facebook then yes it can still run some process even after I close it in Apps Tab but I see the same with Samsung Music Player i.e after I close it I still see a thread in "Running" Apps.

These kind of apps do tend to run a background process to check for updates. Closing the app doesn't necessarily mean that the processes will close. And I'm not even sure even if you turn off all the notification services of an app, all the related processes will close for sure, it depends. Also, if you are using apps like facebook etc, do not worry much about the battery life if you have turned off the background data usage and notification services. It will have very minimal impact, almost negligible!

Question Clearing all apps in the recent apps section

I dunno if other people feel the same way but don't you hate it that you have to scroll all the way to the left to press the clear all apps button? Is there a way to make that show up on the right instead?

Yes, bad design ...

I've submitted a request to google via settings/about phone/send feedback about this device to move the clear apps button to be placed next to screen shot and select options when you open up the recent screen.
It is annoying when if like me you have the habit of clearing apps down, although I read somewhere that Google would preferer you to not clear recent apps so they load quicker when next opened and that their learning adaptive battery preferences help snooze the apps in the background and learns when you are likely to use them next so it so they are ready for you. I'm sure if I'm wrong I'll be corrected about the info.

I mean, it's pointless having it there lol, it's like they sat down and asked each other, would would be the most inconvenient place to put this!

There is little to no reason to actually clear this list. It may help clear up some RAM, but the phone has so much that it truly does not matter.
Apps will go into suspended state after not being touched after some time.

I know this but it's habbit for me and others alike, I just like them to be closed been doing it since I got my very 1st android a million years ago also it's a little OCD to clear things off, for me it is..... I sometimes get frustrated with myself because I'll clear an app that I've just been on and know I'm going back to it but still close it....

This is a bad habit, Google is doing you a favour by making it more difficult.
Clearing the apps will actually make the phone slower and waste more battery. Because it has to load every app from scratch, every time. Every app will take a few seconds longer to open, CPU will be stressed harder, doing tasks it already did a couple hours and would not need to do again if apps were not cleared up.
Obviously the CPU re-doing tasks will consume more battery and the phone will likely die before the end of the day and people will come here and complain about the battery being bad.
Apps being kept in memory is done for a reason and it is the best practice. It's how it's done in every OS, especially Linux.
In iOS, for instance, even if you clear the apps from the list, it won't actually clear everything from memory. and this is the best practice. If the app is misbehaving, go into settings and force kill it. Otherwise, you want the app to be in mem cache.
Do yourself a favour and drop this bad habit.

Agree. At first coming from my S8+, I missed clearing recents just out of habit to keep things organized when switching apps. Now however, I'm finding switching apps via swiping left/right on the bottom of the screen on the P6P to be super convenient. I hardly ever even open recents anymore, and if I need to remove a rarely used app from there it's much more practical to remove one with a swipe than all of them. Get out of the bad habit and save yourself some battery and loading time

The only time I ever clear an app from Recents is when a single app is giving me issues.

Agreed, I dropped this habit a while back as it really doesn't serve any purpose to clear them for the aforementioned reasons!
