Need help with application "0"

Okay, I have been noticing that my battery is draining super fast as of late. I've been messing with my settings to try to get the beat battery life can. I finally went and looked (using spare parts) at what is using certain battery drainers (i.e. network, gps, display) and saw something funny. Some strange app or service that is only displayed by a "0" is using network like its crack! Does anyone have an idea what that is? When I click on it to get info I get a force close error.
If I knew how to take a screen shot I would and post it here. But I'm not home on my pc anyway.
Right now I'm rooted, running Warm Two Point Two RLS 5 and the collin_ph battery tweak.
Thanks all!

Well, you can download an app called shoot me from the market from screen shots. Also you can try looking in applications and force stopping apps that look unfamiliar. You can always do a clean wipe and then reflash your rom and that should take care of your rogue app.

Zero is the process id for root so that is most likely something built in to the rom doing it.

Thanks to both of you. I think I got everything figured out.

Program that shows individual program usage?

I have done everything imaginable to improve battery life and my battery monitor shows that 93% of my battery is taken up by my screen. I always thought this was a good thing as it means my system isnt raping my battery.
Im using syndicate 1.2 and i have everything disabled drm/sns/sys update etc etc.
I just dont understand how my battery gets drained so quick. Honestly with regular usage (no games...just browsing and news) on a regular battery it maybe will last 6-7 hours. Doesn't really make alot of sense to me. Was hoping I could narrow down specifically what may be causing it.
Im using beautiful widgets (static location, switcher pro widget, calwidget and thats seriously it with launcher pro. I should be getting great battery life

try spare parts from the market.

hm good suggestion i didnt know it had that feature lol or i just havent opened the program in so long. I removed pandora/winamp/shazam widgets from my phone to see how that makes a difference.

quick question if you know...i know gps isnt supposed to use battery unless a program is accessing it but i hear people say to turn it off all the time. I have seek droid installed as well as lookout and I'd like to keep gps on but if its draining battery just by being 'on' without being used i'll leave it off.

Yeah, widgits will wipe out your battery. Especially if they are constantly updating....

Or, you can pay for Titanium Pro or Bloat Freezer And freeze apps that run even when not in use like Maps,Poweramp,Root Tools, there are lots that do that I bought Bloat Freezer and found out even Google+ runs when not in use. I had like 16 running unknown to me. Launcher Pro was and I use Zeam....

I have launcher pro and I don't think I can get around its usage I just don't get how the programs are raping my battery while not being used. Like pandora or winamp widget shouldt be doing a single thing unless I click them. Same for shazam etc. I want to have access to them via widget but have them frozen if not being used

You can't have your cake and eat it too. The best thing I can recommend is to put app shortcuts on your home screen, you can afford 1 more tap but you can't magically add more battery.

Also turn down your screen brightness. The display is the biggest drain on your battery than anything else. I can literally watch the percentages click away while browsing or reading through XDA. Screen off I use about 1% an hour. Reading XDA I can drop from the 90's to the 70's in 20 minutes.

Yup and XDA runs in the background when not in use..kind of disappointing. I use this app more than any other these days

Process Monitor

I am trying to get the best batt life out of my Hawk 2.3.4 V4 rom. I would have posted this there, but I cant due to the 10 post min. I pay quite alot of attention to what is being said in the forums, I just dont post alot.
I want to know what processes exactly are eating up the CPU time in the android processes, so that I can get rid of the ones I dont need.

Try looking in the market for an app called better battery stats. Its a really good app and when read correctly it will give you the information you need.
Sent from my SPH-D700 using xda premium

I guess I should clarify. Better battery stats is not a process monitor. All it foes is keep track of how many times each app accesses the CPU. There is also an option for how many "partial wake locks" are being performed by each app. Basically a partial wake lock is when the screen is off and an app starts working while the phone is off. Many people have had good luck with this program. I for one have found that having an alarm on in my phone, regardless of when its going to go off (even 12+ hours from now) will cause partial wake locks. And staying logged into Facebook will cause massive battery drain on my phone. Hope this helps.

[Q] Relatively unfair battery drain issue (Running stock JB 4.1.2 XXDLL4)

Or so I've come to believe it's unfair anyway, I just don't get how some people achieve 19+ hours or so on battery life, with 'heavy' usage as well like they claim.
I have posted some battery usage screenshots if it might be of any help.
When I was using the phone out of the box with an earlier stock firmware, it was the same as of now, even after my current XXDLL4 update. I always kill background apps, from ram and from running tasks, turn GPS off and other unused features, e.g. NFC, S beam, you name it. Like for example with these screenshots, I was using the phone moderately all day, a bit of browsing, some phone calls and a few games. Is 3 hours of screen time supposed to be normal with this battery reading? I don't get it Is there anything I can do to get these long hour performances on battery that everyone else seems to be getting with their note 2?

Im on stock unrooted 4.1.2 rom. Battery life was decent until I went to settings, application manger and then to all and disabled apps that I don't use including some widgets. Eg Simple alarm, learning hub, remote controls, Samsung sync etc and battery is significantly better.
With Whatsapp and Facebook running on the back ground all the time. .. I still manage to get 6hrs screen time.
However you must understand battery life is very much subjective to your signal strength, usage and the apps running in the background. Generally 4 to 5hrs on screen time with heavy usage such as 3d gaming etc is considered pretty good.
As long your phone can get through the day with a single charge, I would say that's good enough and enjoy every features of the phone without worrying about battery life
Hope I helped.

Thanks for your thoughts, another issue that I notice I'm having is this mediaserver battery drain, I've tried performing a few fixed including removing album art, trying .nomedia, even removing all music altogether, but nothing seems to work. I'm starting to believe all these people with 10+ hours of screen on time have been photoshopping the screenshots! LOL! Seriously, the battery life is starting to resemble an old iPhone 4 that I used to own.

Update your rom....

Can you be more specific? Which rom do you know out there that isn't custom? I prefer stock only. If Thanks
Sent from my GT-N7100 using xda premium

Are u able to identify what are the apps constantly running in your background?
I highly suggest u to do these few things for now.
1) update your rom to the latest 4.1.2 rom provided in your country. Go to settings, about device and go to software update or download Samsung kies, connect your phone to samsung kies if you have the latest stock rom.
2) Turn off sync.
3) Run through all your apps settings and phone settings. Turn off unneeded notifications
4) Go to application manager, scroll to all and disable whatever stuff you dont use. If it breaks something, just re enable it.
5) After all of above, go to application manager again, scroll to running applications and see what is running in your phone background.
6) if you have problems with media scan, go to application manager. Scroll to all and clear cache of the following apps. Download provider, downloads, media storage, gallery and drm protected storage and reboot the phone.
Another small tip is I diabled google search, Dropbox, disabled online search under contact settings, disable sync with wifi in gallery settings, disabled talkback, turn off all notifications in google plus settings. Turned off Facebook notofications and auto update.
Let us know if it works for u

Thanks I have already tried all your suggestions. I just dont want to go down the extended battery route, as there are many of them which I dont trust, unless you know a well known brand I could go for?

There are currently no new February firmwares for my country/carrier. The latest one was in December, which I'm using right now.

I think your stats are okay. Because you're using H+. If you switch to 2G you'll see massive gain in backup.
Besides, 4.1.2 literally killed 15-20% backup from 4.1.1, don't know what was ****ing point, but Samsung did it! Just keep monitoring via Better Battery Stats, which apps/process are causing wakelocks, and then do the needful.
'Swyped' from my GT-N7100

It seems like there is too much wakelocks, judging by your stats. You are not rooted, right? If so, it's impossible to diagnose the wakelocks without simply guessing and eliminating which app is causing them.
The maps wakelock caused by Google now, along with AudioOut_2 and media scanner are among the most dire. The first can be "fixed" by disabling location services.

Just for your information. Your battery performance really below par which note 2 it should be.
2hours plus on screen time and 10 hours operating time left 5% was totally unacceptable.
With super heavy use, note2 at least must be able to last 10hours++ with 3.5 hours on screen with 20% left.

[q] at my breaking point with battery drain

I know this horse has been beat to death, I'm just hoping I can get maybe one bit of info that will help me resolve this issue before I just swap out to another phone. I really don't want to, but I'm just so sick of being chained to a charging cord all day. My phone should be able to hold a charge for at least 1 day, I don't even use it that much!
So with my little tirade out of the way, let me give you the facts I've got a Samsung Galaxy S II/SPH-D710, and the battery just drains down so fast, and the phone's barely 6 months old. I've downloaded numerous process monitoring apps, designed to see what's going on, and they all point at WiFi being the culprit. The phone never hits deep sleep because the wireless is keeping it awake. Sure enough if I turn WiFi off and I go 3G/4G all day my battery is fine. Problem is I can't get to that next level and find out what program or process is causing the WiFi to be on all the time. Even more frustrating, every time there's an upgrade like FI27 or FL24 which I'm on now, the battery works fine for a day or two. Then something kicks in and destroys the battery. My thought is it's got to be an app, I just don't know which one.
So before I kick this piece of **** out the window, I was hoping someone could please help me figure out what app/process is the cause of my battery drain.

Get DS Battery Saver. It will force all of your stuff off when you turn off the screen so that it will go into deep sleep.

Get a new battery?

Apps, batteries, ics vodoo it's a host of things that can solve your battery drain issue. Being that your phone is 6 months old I have to rule out the battery. The fact that your on ics is going to be main culprit, stock ics was not the best at managing battery use. There's something revving the crap out of your Wi-Fi, while Wi-Fi is on even while your screen is off there are processes going on in the background that are using Wi-Fi to send receive, update, sync, you name it and all you need to do is pinpoint these processes.
Some apps in the play store can help, but some of these apps can consume battery also, so it's best to delete it after troubleshooting.
If your phone is working properly and your not a social media junkie while it sleeps it should not be using any battery at all, just enough to keep your processor awake.
I keep notifications are sync off on my phone, while I'm out and about I'll check email or do a quick sync if I want to check for some incoming whatever. Most of the time I want info on my terms, not every minute with chimes beeps or lights flashing.
If you use google maps disable background location reporting, location services just use "location and search " disable Wi-Fi and GPS usage for location services.
This is a start, but I recommend Jb ga10 stock/rooted to give your phone a stable os.
I run stock/rooted Jb de-bloated with minimal apps, no games (all the games I like are on my Galaxy Tab 10.1) I use my phone for calls........... navigation and media player while driving. I get 16 to 20 hrs on a charge.

I get about 20 hours on the Vanilla RootBox JB ROM. YMMV. I also had terrible battery life on the stock ROM and every other one I tried. This is the first ROM that's bested 10 hours. Again, YMMV.

what rom are you on? tw? cm?

Have you used Better Battery Stats? Or the JB release candidate GB08?

Not to raise the dead, I've just been busy, but this is still an issue for me. I upgraded to JB GB27, and I love the GUI, it’s such a step up from ICS. But I’m still getting **** for battery life. Yes if I use DS Battery Saver it works and I get good battery life. However all those programs cause flaky restart issues. The phone will just restart for no reason. More importantly it’s not getting at the root of the problem.
IRL I’m a computer tech and I can’t just let this go, as previously stated I’m tired of being shackled to the phone charger. I’ve swapped in a new battery, it’s not the battery. I even turned on the setting “Keep WiFi On > Only when plugged in”. That did improve the battery a little, but I still can’t make it through the day without being charged. I’m on the phone maybe combined 30min of phone calls, 30 min checking email, and an hour or so of miscellaneous watching video etc. I know heavy users that are on their phones all day, or let their kids watch Disney movies all night. I’m not that guy, I’ve had numerous cell phones and never have I had one that couldn’t hold a charge all day.
I will be diligent in monitoring this thread, please give me your troubleshooting tips and I’ll report back with the results.

Downlpaf betterbatterystats. And find the wakelocks.

Can do, will let you know at the end of the day.
EDIT: Actually I read multiple issues with SG2 and BetterBatteryStats. However your wakelock comment made me stumble onto the app Wakelock Detector. Again I'll run it and report back. Thanks for the point in the right direction.

Ive noticed no better or worse battery between being rooted/custom rom and stock not rooted. However my phone gets about 16 hours on average. My friend has an epic as well and gets only 10 hours. I feel as though it depends on the user and apps. Facebook is a silent killer. As is any app that uses backround. Best setup ive had so far is billgeryans Quattro Rom with ds and greenify. I pulled a whopping 25 hour minimal use before charge and 13 hour heavy use day.....

So how do you stop it? Do you just have to close out of every app before you set your phone down?

With titanium backup. You can also install greenify. It puts your apps in hibernation when your screen is off. So basically it's like freezing and unfreezing. Tbh I think it's better using greenify.

titanium can and you can create a widget to do it easily per app.
or

or what I do:
shell commands usind connectbot widgets with a command like this:
pm disable-user com.facebook.katana
pm enable com.facebook.katana
---------- Post added at 07:36 PM ---------- Previous post was at 07:32 PM ----------
so my 2 cents:
1) get a second battery and charger.
2) betterbatterystats to identify "bad" apps and either get rid of them or deal with them.
3) "autostarts" app to stop crap from auto starting on boot that you don't need running as a service.
4) dim screen! huge huge savings. keep it dim enough to use the phone.

Battery issues well I have a solution that won't solve but greatly helps. It's called greenify. It puts all running apps in hibernate mode. It's not like a task killer that just screws things up. U can choose what u want to hibernate and all that jazzy stuff. It's worth a shot. All in all if you want a bada$$ battery efficient rom go with wcx stock rooted rom. It's simply amazing. Hope I was at help

Check out greenify if you're rooted. It removes all currently unused apps and processes from memory, essentially putting them into deep sleep. That combined with ds battery saver and watching your wake locks will drastically improve battery life:beer:
