Process "0" using network - Nexus One General

I have realized that sometimes there is a process named 0 which takes a lot of network usage, even when APN in off and no network usage should be made. I realize this process takes up a huge amount of battery.
Does anyone have idea what the hell is this 0 thing?
I have cyanogen rom so battery usage displays all apps with its names, jfyi

/bump
any ideas? Anything to do with kernel? This process decides randomly to drain huge amounts of battery some days... don't know why :-/

I have this same issue. I can't figure out what is starting it... it is causing 100% wake time too... I have formatted and flashed from scratch to Damage Control 2.07.2 (obviously a 2.1 rom). if I try to click on the process it force closes spare parts.
Could really use this help.

still having this problem with Froyo and I'm using ARHD 3.5 now. this problem has been with me since version 2.1 and it is still force closed when trying to check it out. any ideas?

high awake time since flash to DC

so ever snice i flashed my hero to damage 2.1 rom my awake time is always so high. its always only about 10 minutes BELOW he uptime. therefore, KILLING my battery life. =(
I've been running DC off and on for almost a month now and have had excellent battery life. My awake times fluctuate (right now I'm at 13:30 Up time and 8:37 Awake time) but it hasn't been crazy.
Just curious, what is considered a "good" awake time/up time ratio? Are there better numbers on any of the other ROMs?
before if flashed it. lets say my uptime would be 50 minutes. my awake time would prob only be 2 minutes if i didnt use my phone at all. but now that i flashed it, my uptime would be 50 minutes and my awake time will prob like 40 minutes.
The current Damage Control ROM is bugged and has an extremely strange wake lock issue. I'd suggest using Fresh ROM 2.0d until this is fixed.
is the freshrom 2.0 just like damagecontrol ? i mean i LOVE evertying about DC. i wouldnt want something so different.

it shouldnt be totally different, but even if it isn't it works...or you could live with your battery life.
I don't think it's the ROM. I am running DC 2.7.02 and right now my up time is 21:45 while my awake time is 2:48.
My battery life has been fantastic. Have you tried looking at various radios?

yea after a search...weird i didnt think it worked...i found that this complaint is on almost every rom by at least one person. There are quite a few fixes. biggest one is disabling stock messaging app if used and using handcent or chomp.
Also you can go to settings, about phone, battery, and see what is using the battery.
This isnt for you dooj just quoted on your statement.

I had that happen recently to a friend. Try just doing a factory reset.
Settings -> privacy -> factory reset.
Your phone will still remain rooted and the rom will still remain too.
This fixed it for him.

whats your time without signal? go to settings, about phone, battery, battery use and see whats using the battery and if click on the cell standby i think to see time without signal.
also go to menu, applications, running services, and see whats running and how long. stop the ones you dont use that have been running the entire time your phone was awake.

If you want to remove it, then at the windows command prompt assuming you have your SDK tools path set up correctly:
adb remount
adb shell
cd /system/app
rm [messaging app].apk
I dont know what the name of the messaging app is, but I think it might be Mms.apk You are at your own risk if that removes the wrong app.
You dont have to tecnically remove it. Just disable auto retrieve and notifications in that app.

As for the current Damage Control ROM having a wake-lock issue, what IS the latest version? I am running v2.07.2 (the one before the TrevE mod) and I have no wake-lock, random reboots, or time without signal.
I have not found it to be the rom that is keeping things awake technically. I have tried to figure this one out, and all I can say it seems to be tied to some apps that I have downloaded that starts to throw the awake issue off.
This has happened to me on all 2.1 roms.......after a couple weeks of downloading some apps.
I only use root explorer and mixzing for now and have not had a problem with just those two.
I think I even confirmed that Pac-man was keeping the phone awake, although this is probably not the only one.
anyway, hope it helps.

The only thing that helped my batterydrain

I installed Spare Parts and saw that my phone was never sleeping, even though it was on standby all the time.
This was caused by the location by antenna feature.
Ever since i unchecked that feature i've had around 50-60 hours of uptime, with a few calls and a lot of texts.
hope this helps alot others
With the new firmware the problem of battery dissapears completely
There is a known issue with network location detection in android 1.6. I had the same issue with my galaxy and it was solved. Now that we have root, we can hopefully do the same.
Also, br aware that I have found spare parts to actually stop the phone from sleeping, as well as tapatalk. I suggest rebooting after using either program.

Actually that issue is fixed in the latest update so it's already fixed without needing root.
Which firmware? I know I'm still experiencing it.
RBA020 solved the battery issues for me.
Where in spare parts does it show you if your phone has been sleeping?
you don't need spare parts. Just dial *#*#4636#*#* and click battery history and then the running bar.

I just found that my phone has been running most of the time, I see Running at 100% under Battery History. Then I select Partial Wake usage and see Android System has the largest share. But what part of Android System? how does one get to know?
I know from having a Samsung galaxy and being part of the androidforums community that was going nuts until Simone found a bug report with Google saying that network location was stopping devices from sleeping. We had root so a Dev applied a patch to services.odex and voila! Phones were napping again.

Update after turning location off completely
Well first run with all location methods disabled (I can still enable GPS quickly via a widget when I need to use it)... the battery performance is up phenomenally!!
I charged fully before going to bed last night, then kept the phone unplugged... woke up and found the battery was at 97%. This has never happened to me.
Ok, one thing tho, I use Juice Defender with night time schedule, so my wifi and 3G were off during most of the night. Anyways, its been around 3 hours since I woke up, and I've been using the phone on and off to do some browsing.
The battery is now at 93%.
I do not use any other aid other than Juice Defender... no task killers, no startup editors. Will update on how the rest of the day progresses.
EDIT: my thanks to Inebriatef and adrianoftyriel for pointing this out.

I too would like to hear a bit more. Could the OP please elaborate?
I'm running the latest FW and although my battery life increased exponentially, I find that it's not going to sleep anymore! I had close to 50 hours battery life and now I repeat everything to get just under 20 hours.
I don't use task killers and crap anymore, just before I put my phone away. If I don't, I have a trillion programs running with like 40mb of RAM free. Although I understand this is Linux based, these programs are RUNNING and not idle. All my **** is draining the battery again after a clean reinstall of everything. What a bummer.

@bongd, by latest FW, do you mean the R2BA020? If yes, then you shouldn't be affected by the problem being reported here. I'm still on R1FB001, which apparently has this Android 1.6 bug related to location.
As in my case, simply by disabling location settings (even though this reports that network location is the culprit, I disabled them all), the phone is now able to suspend itself and basically consume very little battery in standby.
Personally, I dont see any issue with lot of applications running and having little RAM left because I trust the Android system to manage it efficiently. Furthermore, the RAM on these phones is not as fast as what you would see typically on desktop systems, so it actually helps having things around in memory rather than aggressively cleaning it out. Checkout this link to understand a bit more about Android task management features: http://android-developers.blogspot.com/2010/04/multitasking-android-way.html
I suggest you use Spare Parts to isolate your battery drain, there might be some app that is misbehaving and hogging systems resources. Also turning off very frequent updates/refresh intervals in some applications is the way forward.
I found through trial and error that fancy widgets keeps my phone from sleeping.sad cause I really want to use it.

Thanks, j4mm3r. I am using R2BA020. It looks like I have some diagnostic troubleshooting to do when I get home.
Sitting here at work charging my phone, it isn't loading craploads of programs anymore. And it seems to be sleeping okay. I'll play around when I have some free time.
Fixed my problem big time
Hey guys,
I just wanted to throw my two cents into the pot.
OK – so after experimenting with Task Killers, Task Managers, Spare Parts, Juice Defender, etc. I came to the conclusion that they (for the most part) did more bad than good. It was getting to the point that I was just starting to accept that “The X10 just has ****ty battery life” end of story.
I also read in a Google released post on the web, that there are a number of reasons that Task Killers, etc. are actually not required to end tasks. Android actually has a fairly intelligent and systematic approach to killing tasks that are not being used. I haven’t used any sort of proprietary battery saver, task ender, startup cleaner, etc. and I’ve been having the best phone performance since I got the headset.
The time now (Eastern Standard) is 3:30pm on Monday. The last time I charged my phone was Saturday evening at 6pm, and currently I am showing 24% battery remaining. Let those numbers do the talking!
My settings are:
Wi-Fi always off unless I am going to be actively using it (browsing)
Using Phone info, I change WCDMA Preferred to GSM Only (enables 2g instead of 3g without disabling data altogether)
GPS always off
Screen settings, brightness, etc. I believe have a much smaller effect than people tend to believe. The SINGLE BIGGEST factors for me, and noticing this huge increase in battery life are:
Settings -> About Phone -> Software Update -> UNCHECK Automatic Search (this constantly searches the market, etc. for app updates and what not)
Cycle power immediately after charging. Once my phone completes its charge, I turn off and then on again.
I hope that some people can enjoy moderately extended battery life as I have. I am SO ecstatic to be at HOUR 43 and still at 20%+
Worth mentioning also that I am on Rogers (Canada) and have not received any updates, so this extended battery life is not a result of a firmware update.
How I Fixed My Batter Life Problem
My Incredible would run dead in about 4 hrs doing nothing. I finally dug into several "task killer" programs and found that about 20 - 30 apps were invisibily running in the background constantly. As soon as I permanently killed them, my battery life went to normal. I can now get about 2 days of normal use on 1 charge. Even a day of pretty heavy use will last almost all day.
So for me, it was all the new apps I installed when I first got the phone that were running in the background. The free "task killer" program was not showing them. I finally found the app called "System Panel." It was the ONLY app that would show me all the "invisible" apps that were still running invisibly in the background and let me kill them. Once I killed them with System Panel, they stayed dead and the free "task killer" program could auto-kill them from them on.
Not sure why the free programs could not see the rogue apps, but my battery life is GREAT now.

I'm running R2BA023 and I am struggling to get a full day from the phone at the moment. It normally lasts around 12 hours and then its flat.
However, I ran the Telenor R2BA020 update and I manage to get a full day with ease.
I have just done a clean install of R2BA023 Generic UK "root" edtion and going to see how I get on. What I did notice before is that the phone was not returning to a idle state.

The process ID 0 is root on Linux and (I suppose) also on Android.
Now ask the question: is your process 0 behaving different from that on other phones?
I have no idea what connections would originate in process 0, but I can imagine things like a reply to a ping fall under this.
I have just done a factory reset. The process 0 usage under network usage had gone.I'm now going to add my apis back on one at a time to see what sets the process 0 bug off. My guess is its got to be something that we all use like facebook our something stupid like that.

What do you reckon it is? I done a factory reset and it still draining away.
I think its the facebook app that hammering my battery. I put apps back on the phone one at a time and when I installed facebook I turned off the update interval and closed the application. After a few hours I pulled my phone out my pocket to find it really really hot and my battery was nearly dead after having 50% prior to installing. I uninstalled the app and now my phone is consuming at a rate of approx 5% an hour, still higher than 2.1 but better than it was. I still have the process 0 network usage issue though. I noticed that if you do a firmware recovery and re flash the firmware into the phone, the process 0 usage does not start unroll the phone has been restarted. I used my phone after flashingfor a few hours with no process 0 in the iterate statistics. as soon as I restarted it came back.

Apparently the '0' proccess belongs to rooting.

Battery dying very quickly - what to do?

My Evo battery is draining at a rate that is all together too fast. I took it off the charger about 3.5 hours ago and it has drained about 30-40%. I have not made a call nor used the net at all save for the receipt of 3-4 emails. I had a rooted phone but I reset the phone back to complete unrooted stock. I have not even so much as installed an app. What can I do about this?
turn off your mobile data when not in use. This will save tremendous amounts of battery.
if you search the forums you should find countless threads on battery and how to find out what is draining your battery and to extend life.
not sure why you would unroot unless you were exchanging it at sprint store but it greatly limits what you can do to help prevent battery drain. If you dont want to mess with much jsut use a rooted stock rom and it is pretty much the same thing as being unrooted but you keep the extra rooted benefits.
your best bet on non rooted device make sure mobile data, 4g, auto orientation, bluetooth etc are turned off. do the HTC battery condition/charge trick. and turn off background sync.
my suggestion is to re root and look into undervolted kernels and many other battery saving tricks found using search!
hopefully it helps some.
I had the same problem OP.
Turns out my radios weren't update.
Head over to the developer section and download the newest radios and stuff.
I've seen significant improvement of my battery life by using Collin_ph Battery Tweak 1 that was offered by Myn's when I flashed his/her's rom. I had my BF take his Evo to work after he come home complaining that the charge would only last about an hour or two and behold, he got through the whole day without having to charge his battery. This is after listening to music at work for 8 hours also. I HIGHLY recommend this tweak for ROOTED PHONES as I and everyone else I've recommended loves their Evo now and have no complaints...I'm at work right now and I'm at 79% and when I usually get home the battery is either still green (full) or orange (med) charge. I'm not sure if this tweak can be used with other mods but I'm very happy with this tweak as it has made my phone perfect now~~
Could be a Rogue app running killing your battery or radios not updated like stated above.
I recently started having the same issue. Advice such as turning of data and the GPS aren't helpful since the device functioned fine with GPS and data on before. Also if the battery was draining at a slower rate on the current radio before, you shouldn't need to update it, should you?
Seems that either something is making the Evo use more juice than it was before or that the battery is not holding the same capacity it used to. For some reason Phone Idle and Cell Standby have been using quite a bit more juice than they used to.
I don't like some of the software mentioned to try and locate anything that could be using more juice since those programs seem to use quite a bit themselves. Either way, what could be doing it that would come up as Phone Idle or Cell Standby in the included battery monitor? Wouldn't anything else come up under Android System?
The battery draining that quickly is not normal even with background sync, GPS (idle), 4g, data, or anything else on. There is another issue which must be solved. To troubleshoot so far I've tried another battery (same thing happens) and now I'm trying with everything turned off. If I can isolate what was causing my sudden rapid battery drain, I'll update everyone. This just started a couple nights ago for me. I think I'm on the latest radio, but I'll check.
Last post sums up my problem perfectly. I have an extended battery that lasts half the time it has over the last 4 months. Started with the radio updates. running myk
Use the battery usage functions of 'spareparts' to determine what's consuming cpu or preventing the phone from sleeping.
Can't fix the problem until you've isolated what's at fault.
Turning off mobile data will indeed fix a problem of some app trying to access the network, but it won't solve the actual cause.

I think juice defender does this automatically when the screen is off.
In the case of my phone, and I believe the OP's, we don't have any rogue apps or things running in the background. I know this phone like the back of my hand. I have completely uninstalled unnecessary apps like facebook, twitter, all things like news and weather are on manual update, i don't keep 4g or gps on, and I use wifi at home. I turn off 3g in terrible reception areas. I'm not a new user who doesn't understand the basic ways to save a little battery. I'm pretty sure the OP isn't either by his post. I use my phone the same every day. My chinese extended battery would last me easily from morning to bedtime with 20 to 30 percent to spare. Now I can't get near that after the radio updates. Since it's been well known that something is weird with these current updates, I've downgraded to 1.77 to see if that helps. My phone was sleeping fine though, so I don't know how much it will help. Always some BS with this phone.

I appreciate it. I really do. But that is exactly the things I'm saying are already off. GTalk is turned off immediately on my phone from the jump and latitude has never been opened. It's got to be radios. I guess I'm not really asking a question, I'm just telling the OP he isn't alone.

this is the thread with flashable .zips of alllll the radio updates ever out for the EVO.
http://forum.xda-developers.com/showthread.php?t=715485&highlight=radio
if you are having trouble after a radio update, just try some of these other radios and see if that helps
Your best bet would be to root your phone again and give one of the SBC kernels a shot. I'm running CM 6.1.2 along with Zendroid 1.1.0 BFS AVS SBC and I can easily get 16+ hours with HEAVY use. And when I say heavy use, I mean hundreds of sms, dozens of calls and lots of websurfing. You will love the SBC kernels. Give it a try.
PS. My name is HondaCop and I approve this message.
We can offer suggestions until we're blue in the face.
First off, the OP needs to provide specifics of what's installed on the device, including rom, kernel, radio, etc, not to mention the hardware version itself.
Assuming it's not the known pri /rom conflict, then determination needs to be made as to what's actually consuming cpu - see first sentence above.
Need to use a systematic approach to troubleshoot this, otherwise it's a waste of time.

That sounds like a very weak cellular signal is forcing the radio to keep searching for it, draining the battery very quickly.
One way to somewhat alleviate this problem is to force roaming, to connect to a provider with a better signal.
"Roam Control" app does this (Market).

We can offer suggestions until we're blue in the face.
First off, the OP needs to provide specifics of what's installed on the device, including rom, kernel, radio, etc, not to mention the hardware version itself.
Assuming it's not the known pri /rom conflict, then determination needs to be made as to what's actually consuming cpu - see first sentence above.
Need to use a systematic approach to troubleshoot this, otherwise it's a waste of time.

Actually,
some android users looked at the posting date, saw that the op hasn't updated in over 24 hours, wanted to complain about it, decided against it, posted quickly the most useful idea they had.
All that while doing real science.

Serious battery drain with minimum usage

Hi all,
The battery life of my 4month old SGS is becoming shorter every week! I can 'almost' last a work day (8 hours) with a fully charged battery and minimal use.
I had this problem also on the stock firmware, Darky's rom 8.x was a slight improvement (much faster tho!), Light-ning rom and Darky's rom 9.x.
Everyday I charge my battery untill it is full, when my alarm goes off it's already at 98% (it's still hooked up). When I'm in the train to school, my battery already dropped around 86% (being idle). I check some mobile websites, my e-mail and read some twitter messages.
Because I know services as Twitter (I'm using Tweetdeck) uses alot of resources and battery, so when I'm done looking I always shut down those programs. And I often do an 'end all' task in the 'System' app which I purchased from the market lately to monitor my battery.
During the day the only thing I do is check my mail and some websites, but not for long, mostly it would be around 5minutes or so. So WiFi is turned OFF, GPS is turned OFF, and only GMail synchronizes with default settings. So what's the deal? Is my battery slowly dieing because of oldness, or is there another problem?
Thanks in advance for helping me! You're doing a great job!
Sincerely yours,
S1GNZ
after flashing your custom roms of choice... did you ever do a battery calibration?
like let your phone drain till it dies on its own... turn it on againa nd let it die again to completely drain it to the point where u cant even turn it on.
Then plug your phone in to charge and let it charge to 100%. Keeping the phone plugged in turn on your phone into recovery. Then clear battery status.
Then reboot your phone into normal mode and let it continue charging till it says 100%. WHen you unplug your phone it SHOULD say 100% still.
This normally fix the problem but if you notice that your phone is dying quickly still then PM me.
One small advice,try logging out google talk,of-course if you are not on it much,it will give you at least 2-3 hrs more.
Also,there is already a thread active on this forum 'dont kill your phone
,give it a life' give that a read.
Mainly this battery drains are there because of apps doing sync. or polling.identify them and adjust settings.

I've been browsing these forums lately, and I've also come across a thread which advice is just the opposite and that you should NOT do this, any advice if that's true? And is it also true that deleting the batterystats helps?

Am I auto-logged in on Google talk? If so, how do I log myself out :$? So Google sync might drain it? (Mail, Agenda, Contacts?)
Thanks for the quick replies! I really appreciate it!
Sincerely yours,

I am not 100% sure if you auto logged or not.I believe not but if not so , then open app,press menu/setting button on phone,select logout.also if you not intending to use data network,press power key till you see a menu turn off,data network,turn it on when you need it.These small things saves some power.
If you dont want to mess around with this little twiks then 'juice plotter' is the app for you.it will manage lots of things and defi. saves battery.
BTW based on your usage desc., I think I use it in similar way ...almost and yet phone makes ~2 days.

You of course wouldn't be doing this alot nor should you NEED to do this often. It's only something you do when you're experiencing what you currently are.
Personally I have no idea why anyone say u "Should NOT" do this.. it's not like you're altering anything hardware wise. It's mainly software and power usage aspects.
Like I said to each their own. Some people say custom roms are a "No-No" cuz it messes with the phone in more bads than good and some says stock roms are for noobs. You dont HAVE to try what I said, it's merely a suggestion of fix or methods that seems to solve the problems others have encountered.
Clearing the battery status pretty much resets it's counter to 100% and from there it will "calculate" the life of the battery from full to empty. It's a calibration thing.
Now on regards to usage, keep your data plan off and auto-sync off when you're not using it. Leave your wifi off and gps off as well.. pretty much keep anything you dont need off until you need it. Some samsung apps does a background run thing where it'll auto turn on and auto run in the background which drains ur battery quite badly. If you don't use goggle talk or samsung chat apps, there are many ways to remove them completely so it won't mess with your battery life
Simple you installed a rom with multiple posts on battery drain problem .
A rom that also tells you about battery drain problems /fix on its front page .

Okay! And you're right, it logs me on when I start the app. But I logged me out, just to be sure. I know about turning of the mobile data traffic, I'll see how much it saves. I think I came across juice plotter, but I'll look into it. Thanks!

Don't be offended by what I said! . I only wanted to make sure I'm doing the right thing, I appreciate your criticism though. I did what you said and fully drained my battery yesterday, kept it charging overnight, cleared the batterystats through recovery mode and at the moment it's charging till 100%. I will see if it helps!
And according to my usage, I have Wifi and GPS turned of as default. And because I reinstalled a new ROM inclusive data wipe I don't have much chat apps installed, maybe there are some default apps that don't show up in the 'System panel' app though?

Care to explain a bit further?
FYI, I installed these ROMS:
past: Stock firmware 2.2.1
past: Darky's ROM v8.0 Gingerbread edition
past: Light-ning ROM 2.2 (if I'm correct, it's probably the latest)
current: Darky's ROM v9.2 Extreme edition (9.2 should've fixed the battery drain, am I right?)
Can't thank you enough for the replies!
Sincerely yours,
S1GNZ
im having similar problems too. calibrating doesnt really make a difference.
i installed an app called task identifier which is brilliant it tell me whats happening when the phone is asleep. the only trouble is i dont understand what these processes are so i cant disable them.... is there any sort of app out there that completely logs / signs you out of every app ??
i have 108 apps (not including system apps) and its hard trying to eliminate the battery drainers
Care to explain a bit further?
As it says post lots of with battery problems big big percentage running Darky rom .
current: Darky's ROM v9.2 Extreme edition (9.2 should've fixed the battery drain, am I right?) You would have to ask on dARKY Post .
Look at Battery drain thread LAST POST OR SO MAY BE OF INTEREST .
I am of the opinion that if a rom breaks something then installing more roms will often not fix the problem . I prefer a blank completely wiped phone in such cases with no trace of any rom left on it .
jje
@azzledazzle 108 apps? really ????
I don't have that much on my PC!
I think we should start narrowing down which apps drain most juice. I've been using Advanced Task Killer just to narrow down a couple.
example:
Sound Hound - starts on its own
Facebook had an issue with notifications push, when disabled, it still sent notifications to my phone. But I think they fixed it in the latest version.
We could start adding versions to know which app is a 'juice drainer'
