[Q] Could someone clarify?

Okay, so I hear in FroYo that you're not suppose to kill and end tasks? Does that means services as well? And if I wasn't suppose to kill them, then wouldn't that make my battery life worse because of all the things running in the background?
TIA

You shouldn't use a task killer in any version of android from Froyo on, froyo handles its memory management extremely well when left alone, using a task killer could result in apps constantly opening and closing in the back ground, which would use a lot of battery .

Alright. I got rid of my task killers. Is ending services fine though? And what about the task manager that the phone provides? (I'm guessing the second one is a no?)
And what other precautions should I take for battery (other than having low brightness, of course)

Only use the one built into the touchwiz framework if you have an app running out of control hogging resources.
If you're looking to improve battery, I strongly suggest Juicedefender with ultimatejuice, I have almost tripled my battery since I started using them.

I use the Advanced Task Killer for Froyo. Several apps I have like the Weather Channel and stock browser lower my available memory to a minute amount of what it was at boot up and do not reload if killed.

The amount of memory available on your phone is supposed to become low. Apps are stored in memory when not being used. This does not take battery and allows the program to start in a faster fashion then otherwise.

I'm sorry guys, but the information given in response here is really dangerous. Yes Froyo, and all versions of Android have built in memory management. HOWEVER, it is the job of the application developer to use the proper calls and closes to make sure the application isn't holding onto resources when in a background state. This is NOT always the case, and is constantly overlooked on all OS platforms, especially with how fast application development is happening on mobile platforms.
YMMV, when and if you should be using task killers.

No it's not. There is only 337MB of RAM available of which about 150 is used by system. If I keep loading apps that stay in memory when not being used I will have no resources or memory available for additional web pages or other apps. Why should the Weather Channel app load 50 MB of memory and stay there if I use it twice a week? When an app is closed I want it out of RAM. I can wait the 50 milliseconds to reload if I want to use it again.

Here we go again another argument of task manager for android
For me i use advanced task manager to kill some apps to speed up my phone a little and also use it to switch between programs that are already open where as if you try reopening some programs the restart,
I also ignore apps that i need to open and stay open like beuatiful widgets, word games to get more reliable notifications and widget locker.
I freeze with titanium some services such as drm and sns...

Free RAM is wasted RAM. Unless your trying to track down rogue processes, task killers are totally unnecessary.

What that article hints at but doesn't exactly explain is that due to how the Dalvik JIT works, killing those apps that aren't actively consuming CPU will cause worse performance over the long run. The JIT has to spin up everytime the app is loaded - if it is already in memory then it's already optomized.
At least that's my understanding! I could be totally talking out my arse
EDIT:
Here is its straight from the Dalvik lead dev.

Well don't know about performance but yesterday killing apps with ATK Froyo especially the browser, I came home with 62% battery left. Today had about the same use but disabled ATK and never used it and came home with 31% battery left. ATK is doing something for my battery and will give up apps loading quickly for battery life any day.

[Q] task killers?

Hey, I noticed that in the screenshots section that everyone has a task killer, aren't they bad for android? I've read that they were needed for android 2.1 and down, not after Froyo.
So, do I need one? Why? Why not?
Thanks guys.

samsung roms (even stock) have default task killer called "Task Manager", for active apps and if you go to Settings > Applications > Running Services, you can kill apps running in the background or cached processes. The difference is, the default tasker does not have a "Kill All" feature.
Task killer is, well not recommended, because Android has "Low memory Killer" feature, which, from the word itself, Android will kill apps as memory is needed.
It's still up to you if you want the default tasker, or a 3rd party one.

I hate that Samsung put that there. I've always been told that you let android do its job, unless there is a runaway process.

If you ask me a task killer gets you more battery life and helps reduce data usage by killing apps that you are not acctually using.
Sent from my SAMSUNG-SGH-I927 using XDA

yes but even if you kill some apps they reopen on their own. I am referring to the stock Rogers rom and that dam AP program.

the reason task killers are considered bad is becausw most people blindly kill everything. your phone has a lot of tasks it will automatically relaunch, thus wasting more processor time in the end. if you pay attention to which processes these are and exclude them from your kill list, you can safely use a task killer.
i also suggest apps like autostarts, lots of stuff like to start that dont need to.
im newly registered but not new here! just picked up a glide yesterday and put cwm/osi on already. a keyboard is a must for me and this was the nicest phone i found with one. my d1 was overdue for retirement. i use sipgate/google voice for free calling, texts and vms (wifi) so thankfully carrier didnt matter. very happy with this thing so far. cant wait to see some ics roms?

Advanced task killer shows you which apps automatically restart and lets you disable them from being killed
Sent from my SAMSUNG-SGH-I927 using XDA

Automated task killers generally are bad voodoo because they interfere with Android's own memory management system. Android micromanages memory like you wouldn't believe, and task killers will only slow things down by interfering with it. In particular, you'll lose significant performance and battery life as the phone works harder to reopen apps that could have just been sitting around in otherwise unused memory as intended by the OS. (And of course, the auto-re-open thing mentioned above.) I used to keep a task killer on my OG to troubleshoot misbehaving apps (sometimes killing the process and forcing it to restart would right some issues), but now that Android has the running services dialog, there really is no need for task killers at all.

It was an excellent phone. Mine finally locked up the other night while I was out and totally died. Doesn't even get the M Moto symbol when you start it up. It had been dropped countless times, entirely submerged in a puddle, whiskey spilled on it. But it soldiered on until the other night. I was even running a very broken ICS ROM (dead project now) on it and it was just as fast CM7. I ran it constantly at 1GHz which impressive for a phone that was stock 550Mhz. Most phones, even the Glide, you can't overclock by more than double like the D1. The fastest kernel I ever had on it, I had edited a version of ChevyNo1's 1.2Ghz kernel to allow 1.3Ghz. I ran it like that for a few days and it was stable.
Great phone. It truly deserves a burial at sea with a 21 gun salute.

[INFO] Why You Shouldn’t Use a Task Killer On Android

So i saw many posts on which people have asked as to which task killer should be used !
and then i stumble upon this site which provided me the details,
*I HAVE NOT WRITTEN THIS*
sources-by Chris Hoffman
http://www.howtogeek.com/127388/htg-explains-why-you-shouldnt-use-a-task-killer-on-android/
Android Doesn’t Manage Processes Like Windows
Most Android users are familiar with Windows. On Windows, many programs running at one time – whether they’re windows on your desktop or applications in your system tray – can decrease your computer’s performance. Closing applications when you’re not using them can help speed up your Windows computer.
However, Android isn’t Windows and doesn’t manage processes like Windows does. Unlike on Windows, where there’s an obvious way to close applications, there’s no obvious way to “close” an Android application. This is by design and isn’t a problem. When you leave an Android app, going back to your home screen or switching to another app, the app stays “running” in the background. In most cases, the app will be paused in the background, taking up no CPU or network resources. Some apps will continue using CPU and network resources in the background, of course – for example, music players, file-downloading programs, or apps that sync in the background.
When you go back to an app you were recently using, Android “unpauses” that app and you resume where you left off. This is fast because the app is still stored in your RAM and ready to be used again.
Why Task Killers Are Bad
Proponents of task killers notice that Android is using a lot of RAM – in fact, Android stores a lot of apps in its memory, filling up the RAM! However, that isn’t a bad thing. Apps stored in your RAM can be quickly switched to without Android having to load them from its slower storage.
In summary, you shouldn’t use a task killer – if you have a misbehaving app wasting resources in the background, you should identify it and uninstall it. But don’t just remove apps from your phone or tablet’s RAM – that doesn’t help speed anything up.
Empty RAM is useless. Full RAM is RAM that is being put to good use for caching apps. If Android needs more memory, it will force-quit an app that you haven’t used in a while – this all happens automatically, without installing any task killers.
Task killers think they know better than Android. They run in the background, automatically quitting apps and removing them from Android’s memory. They may also allow you to force-quit apps on your own, but you shouldn’t have to do this.
Task killers aren’t just useless – they can reduce performance. If a task killer removes an app from your RAM and you open that app again, the app will be slower to load as Android is forced to load it from your device’s storage. This will also use more battery power than if you just left the app in your RAM in the first place. Some apps will automatically restart after the task killer quits them, using more CPU and battery resources.
Whether RAM is empty or full, it takes the same amount of battery power – decreasing the amount of apps stored in RAM won’t improve your battery power or offer more CPU cycles.
hope u understood!
words of wisdom by fellow-mates
go into settings - apps and see how many running apps you have. now go to cached apps and see there, how many apps there are. you see? nearly 50% of those apps discovered by you in the processes are apps that you didn't opened ever but they are still opened and running. why? because that's how linux manages its resources. instead of having free ram for no use (what's the point of having 14gb of ram when you only use 1gb), linux fills all the ram blocks with useful apps or apps that you are running frequently so that when you call that app, it will bring it on the screen almost instantly. this my friend, is called multitasking.
and no, you are wrong. if you use a task killer killing the apps every 10 minutes, the cycles the whole system does - opening again apps and caching them, task killer closing them - results in much more functions done by CPU => more battery spent. even if you say that the battery life its the same, you are wrong. when using a task killer IT MIGHT drain your battery with 0.1% per hour. it's not that much, but IT EXIST.
oh and yeah, one thing: android has its own task killer. that's why you don't need one app to kill your other apps. because android its doing it by itself. if you don't believe me, strip down one kernel, open the init.rc file and find the values for task killer.

I understand this response, but I don't believe it. Task killers has always helped me in every matter. Even on a computer it helps greatly.
Conclusion: I noticed the same battery life using a Task Killer, than not using a task killer.

Low memory!

How much FREE memory do you guys have when in normal usage (with browser, Facebook, whatsapp, tapatalk open..)??
Here I usually get 200 free, so I constantly have to free memory (it goes from 200 to 450, but few minutes later, it will be the same thing).

Look at what is running. It sound like something is running in the background that is sucking up the memory. If you do a reset and re-install of everything, before you find out what is causing the memory problem you may be right back to square one.

I agree with this, when your talking free "ram" as shown in the task manager , it is what is running at the time, not what is installed?
In my system i have not seen the "ram" ammount drop below about 350m ever.

Usually ranging between 200-400 free. Usually if I close the browser and clear my task manager, I can get higher. The thing is, why would you want all that unused? If your battery isn't being drained and your phone isn't lagging, you should be good to go.

Hmm!!!!!
only 200 MB free??
I have 500-700 free everytime!!
well, even if it is only 10 MB free, you should not worry about it(its a smartphone), until it affects performance of battery life!
to check whats eating up your RAM, go to settings>>general tab>>apps>>running tab!
you can also go to battery settings to check the most power hungry apps!
or you can install DU Battery Saver!

PsykoGeek ram or memory is what I was talking about but that also includes the apps or software that is installed on the phone also If the underline problem is not found first, anyone can do a factory reset and re-install the app and there is a very high percentage that it will come back.
I would look at the app that I have downloaded and start to turn them off one by one and see which one could be the culprit. After you found one or two, see if you can live with out them.

High RAM usage is actually a good thing on Android unless you use a lot of emulators like I do. On PC, low RAM is good, but on here the more RAM that's used the better it is. Makes opening apps much faster. What would be killing the battery is an app keeping your device awake even when the screen is off.

[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!

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!

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..
