When I check the battery useage on my Galaxy Tab (T-Mobile), frequently, the biggest user is Asphalt 5. This doesn't make any sense....I haven't used the app and when I check the running applications, it doesn't show up. Also, if I go to the application to force close it, the force close button is greyed out....I don't think the app is running. Why is it showing up in my battery useage screen?
Same thing happens to me on Shift (Need for Speed), it is a power drainer. I eventually de-installed it.
I have Titanium Backup on my Tab. I used the "Freeze" function to block Asphalt 5 from having access to the system. Now, it doesn't show up in the battery useage screen. I like playing the game occasionally so I didn't want to uninstall it. Actually, since it comes as an OEM app on the T-Mobile Tabs, I don't think it would be a good idea to uninstall it.
Anybody got any ideas how/why the app was putting a load on my battery even when it had not been used?

So, after installing Task Manager and opening it I had 31 applications running in the background! Yup, you read that right, 31!!! I ended them all and started playing around. I would launch and app, hit the back button and then go into Task Manager and there it was, still running. I launched several applications hitting back aftewards and they were all still running. I even tried hitting home aftwards and still running. Oh, and I had some apps running twice!!! WTF!?!? Looks like I found a major flaw in the new 2.1 OS.
This is normal android behaviour.
Apps are only shut down when the phone runs out of memory, however if the app is not doing anyting it will be paused and not use any battery / cpu.
And since the nexus has 512MB RAM it can have a LOT of open applications
If it is a background app (like im) it usually has an exit button in the menu.
Apps always run on android if you don't end them with a task manager.
Ya, normal behavior. The app actually has to intentionally end itself when you press the back button for that to really end it. I wouldn't worry about it, though. Apps in the background tend to use very little RAM and CPU.
Not sure why people are freaking out about apps running in the background... This is normal and Android does an amazing job of freeing up memory by killing apps as NEEDED.
Hmmmm, guess I never looked at it that way. I do notice it gets a little sluggish when all of that is running in the background. I'm just used to my MT3G. I've NEVER seen that many apps running at once.

try two and two-thirds the amount of RAM and that would explain how you get so many apps running lol.

Ha-ha, good point!!!
From my experience the apps never close it is set to idle and is stored in the phone memory therefore decreasing startup time and allowing for a better multitasking experience but on all other previous android devices there wasn't as much memory so only a few apps could run at a time before the memory would be needed so something would get closed.
You're used to having 37.5% of the ram the Nexus One has
Now here's the question: does having 31 apps open affect battery life?

It depends on the applications. If they just sit quietly when suspended (in the background) and don't do anything, they will have no impact on battery life (because their threads will never schedule/run). If they continue to do work while in the background, that will have some impact, however, unless they hold a wakelock (something they need the "keep phone from sleeping" permission to do), they will have no contribution to battery consumption while the screen is off and no other apps/services hold wakelocks.
In short, "it depends."
The menu / settings / about phone / battery use panel tries to give you as much information as possible about what apps/services are consuming your battery.

Yes. Traditional multitasking (WinMo, BlackBerry) phone OSes will not close an application (or program, on WinMo) until you tell it to close, or it decides to close itself. This is a resource hog, and results in the freezing up or running painfully slowly that we have come to expect from those devices. The iPhone always runs fast because it ALWAYS closes an app--no multitasking whatsoever--so it never runs out of resources and slows down. It "pauses" the app, then closes it, so when you open it, it resumes right where it left off, as if it were open the whole time. The downside is nothing gets done in the background--which is why awesome apps like Locale or Screebl won't run on iPhone. Android is the best of both worlds. It leaves apps running until it NEEDS to close them. When resources run tight, it pauses apps just like the iPhone, so it stays running fast, but as long as you don't overload the system, you can run background apps. And background services will stay running.

I'm sure it does some, but with that monster of a CPU, and as little power as apps use when they're sitting in the background not doing anything, I'm guessing it is a negligible difference. But that's why I love Advanced Task Manager's auto-end feature.
i lol'd -----------__________----------------
When you have 31 applications running, is there a hardware key that you can press (perhaps with a third party software) to show those which are running, and to switch to anyone of them instantly without resorting back to the application menu? Also, does this same tool let you shut down an active tasks in order to conserver memory and battery life? I understand that a long press of the home key only shows the last 6(?) application launched but not necessarily the currently active tasks.
On my jailbroken iPhone, I'm used to be able to double click the home button to show all active tasks, and there I can switch to or terminate anyone of them. While running an application, I also have the option of long pressing the home button to end it directly so that it does not continue running in the background. If I do a normal home press, the application will continue running in the background, and I'm presented with a screen which lets me jumps to any of the desktop in order to launch new applications.
I hope I can have the same level of convenience here.
All of the applications in the backround are essentially in hibernation - it is part of the way Android manages the RAM. I think it's great.
I use task manager to kill all apps running and i go back into tasl mamager and some apps are running again and i haven't started them.

This is probably the 43rd thread on this topic.
This is what Android does. Programs are open, but not active, and thus, aren't doing anything to your phone. Unless you've got a poorly coded third party app, then leaving the programs open should be fine.
Oh really so even if maps or browser is in the background it's not accessing 3G data. I find when a lot of apps are open the gets a bit slugish
Sent from my X10a using XDA App
Shouldn't be. Then again, you can always install a 3G use monitor and see if it goes up significantly while you're not using the phone.
If your phone is getting sluggish, when you're done with an application, use the Back button to exit it, versus hitting home. The home button leaves the app open, back quits out of it.

This is not correct. Back does NOT always "quit out of it". I have plenty of apps that still run when I press "back". With most of my apps I use the "Menu" button and look for a "quit" option, otherwise they may well be left running.
They may not be supposed to be running, but they often are, regardless.
I use JuicePlotter (with JuiceDefender and UltimateJuice) to see what is going on, along with SetCPU to throttle the CPU speed when the screen is off, and if I leave the wrong program running (e.g. by "backing out") it can increase the power usage significantly.
Programs are open, but not active, and thus, aren't doing anything to your phone.

Perhaps this is the way it's supposed to be, but it's not always the case. I don't think it's safe to make a sweeping generalisation that ALL programs behave like this. Look at, for example, "My Tracks"... if I "back out" of that, it still runs, collecting my GPS data, slowly draining the battery. But if I kill it with a task manager, it's gone.

Well, of course if an app is in the middle of collecting data (GPS, IM, Mail, or background service), it won't close, and you should stop the processes before quitting. MyTracks, for example, is made to run in the background, and will continue running, unless you've stopped your track, saved it, and then backed out of the program.
So I searched and could not find a thread that compiled tips and tricks people use to increase their battery life and get the most ram or memory available.
This way we can put everything together so you don't have to search through a bunch of threads or posts to get information.
I'll start with mine first.
Battery and memory usually go hand in hand, but specifically for the battery I use Juice Defender (Ultimate). I got it to last 31 hours before with minor use. Even the free one said it increased my life 1.5x
I use Titanium Backup to freeze certain programs that run in the background, like the social networking ones since I dont use those along with wallpapers and non-essential system services like the Weather and date/time services. It would be nice to compile a list of all the services you can freeze without messing up the phone, I usually freeze a couple and then test my phone out.
Not having a lot of widgets or background programs running also helps.
I found programs that prevent start-up programs usually fail, the app starts anyways. Task killers also don't seem to work, the app just starts back up. The only one I have used with some success is "Free Memory", it seems to work.
I'm interested in other peoples methods, along with their normal battery life and how much free memory they have.
Somehow I went from having around 450MB free to only having 250MB, which really gets bad if I want to use the webtop and have a bunch of crap open. I might try to reflash it and start over, I went a little app crazy for a few days.
If people want, list the (system) apps you were able to safely remove along with ones you were able to freeze and I can make a list in this post. I would add mine but my phone is acting up right now.

No, I'm not kidding either. I have three batteries for the Atrix. I go through about two a day. I run them all the way down, phone shuts off, I replace, and I have a 100% ready to go. Saved me in many instances. It sounds really convoluted, but it works.
I recommend installing widgetsoid and actively managing wifi.
Check out an app called Watchdog.
Basically what you should have instead of a task killer.
Instead of killing tasks wantonly, Watchdog simply monitors the CPU % each task/app/element running is consuming. You can custom set detection thresholds or leave the defaults, but whenever that threshold is crossed, you can get a little alert for it (customizable too). It tells you the app that's been acting up and give you the option of killing, ignoring, or "whitelisting" (permanent ingore, basically) it. The paid version also allows you to "blacklist" processes (permanent kill).
I would definitely recommend it.
hi everyone i am looking for application that really saves battery for non rooted phone
i used greenify but phone gets laggy after it
Actually there are plenty and you don't really need any to get good results. For system applications, that can't be disabled/frozen we have package disabler pro, everything else can be manually force stop. The only problem is you got to spend time to learn which programs you need and which you don't. To give you example I fully charged my phone last night, about 11:30 PM, got up 6:30AM and had 99% left. Once you stop programs that you don't use from running in the background, it will be like a new phone. To put it in perspective, just few weeks ago I had battery drain over the same night period, same phone 20%. You better believe the phone didn't last me whole day. All I did is manually force close all the programs that I don't use ATM. The are programs like Android assistant that make this process more automatic.
The phone already has a built in app that puts unused apps to sleep.

I'm not sure what putting app to sleep does, when I do, it still seems to be active and you can still force close it.
If you run any program once it will stay active in memory for 3 days and it will reload even if you restart the phone.
My problem with this approach is that some programs I use rarely, for example test internet speed once a month, when it seems slow or play a game to kill some time on the weekend and yet those apps stay active for days, unless you manually force close it. Even Google maps which I use for traffic info twice a day during commute, doesn't have to be active in memory when I'm working or at home and yet there is no way to unload, except manually force close it. And the difference in loading speed I can't tell without the stopwatch even if I actually would ever care. But those apps run in background and eat your battery and I can see it very well at night, when my phone should be on standby and sometimes instead runs full steam.

thanks for reply i bought package disabler pro today and have put some aps on disable
then i looked up xml file for it. one usser said that its the best configuration for that app but some functions were not working for example wallpaper changer battery stats and etc
i am looking again for best xml file to use that app correct
Here's my list, I took someone's basic list of 90 or so apps and added a few more. Everything is running stable with no force closes. I have AT&T bloat disabled so you might have to tweak the list some. I am also using BK Disabler but I'm pretty sure my XML will work on package disabler pro.
The biggest pain is to figure what are you using and what not, since everybody is different and one set fits all approach doesn't work. But you got to do this once. Also I would suggest not to uninstall anything, you never know what you may need 6 months from now and some system apps are not easy to reinstall.
Is it me or is the app management still buggy? I had this problem on OP3 too [emoji848]
I was editing a video, when done I went to SoundCloud to download a music file. Then I went back to recents and the video app had to start again, making me lose the video I made [emoji849]
What is the use of 6, 8 or even 10 GB ram if the most recent app gets killed?
Very frustrating indeed
Yup, likewise. Particularly when the screen is off, background apps get quite aggressively killed. I've seen this for runtastic and cf.lumen.
I have the same problem.
Have you tried disability battery optimization feature?
I read few minutes ago that it can help and I'm going to try this.
You can also lock the app in the multitasking screen, using the 3 dots. I use it for Plus Beat to cover the missing led.
1. You can disable the battery optimization.
2. It may not be the phone but the app itself that is wonky. The reason I can say this is because I often times play a game and take a break to scroll through social media and reply to somethings and go back and the heavy game is still open. Part of that social media is youtube by the way.
