[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.

[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.

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?

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.

[Q] Don't keep activites -developer option saves battery life?

Does enable this option help save battery life? as the process is suspended once user quits it. We all know some roguewares would keep themselves active even though not running forground and draining tons of battery.

Unless you are trying to debug an app do not enable this.
It's for developers trying to develop and debug their applications behavior.
MAYBE if u have rogue app installed it may help JUST for that app. But that's a BIG maybe. And then it could cause other apps to have to relaod constantly which will DEMOLISH battery AND performance due to higher CPU usage.

The developer setting for kill all apps upon exit is NOT the same as clearing recents. It isn't doing the same thing.
Which apps by the way would you say are "staying active" ?
You can check to see if it is those apps specifically that are causing drain by using apps like Gsam battery monitor (my personal choice due to its user friendliness) or better battery stats app. In Gsam battery monitor you can open the app usage section to see exactly which apps used esactly how much battery/CPU wakelocks/time held awake/background CPU vs. foreground CPU/ etc....
I would say that MAYBE for a very specific type of usage that this option may help in battery life. But it without a doubt will eventual degrade performance, due to more CPU cylces needed to fully open an app from scratch vs having it cached in ram. The setting is for sure meant for developers trying to debug their applications behavior and not meant for users to get better battery or performance. If it WAS meant for those, it would have been enabled by default. It will surely mess up multitasking, which is what android is really all about. TRUE multi tasking with apps running in background. So that is what would really depend on your usage I would think.

I think this usage suit my usage very well, I use my phone briefly for calling, maybe very rarely webbrowsing, or sometimes wechat, so I want an app to stop completely once I finished using it since I probably won't open it again in 3,4 days....

I only use webbrowser when I was outside and need to lookup an address... no, I don't even use facebook.

[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

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..
