Android System keeping the Xoom awake?

I noticed this recently so I'm guessing it might be related to an app but now my Android System keeps the Xoom awake always even with the screen off. Anybody else with the same problem? If so what apps do you have installed? Maybe we can find the common one amongst us that is causing this. Luckily the battery is so good that this isn't a huge issue but I want to fix it.

Having the same issue. Wifi only model, I had wifi off for my 1hr commute to work, and it was awake the entire time.

It's definitely an app or something because I know in the past it hasn't done that at all. Can you list what apps you're using? Or if yours is new enough maybe do a factory reset and see if that fixes the problem?
Either way it's definitely software not hardware.
P.S. I have a Verizon XOOM.

What do you guys mean by the xoom staying awake? the screen not turning off or the android system not going into a sleep/standby mode.

If you go into Settings -> About -> Battery and you click on Android System it will say how long it's been awake. Mine currently has an awake time that equals the total time the Xoom is off the battery - i.e. it never is not awake. The screen turns off fine and the battery usage is low but not as low as if the Xoom was sleeping. When it's sleeping it goes into a lower power state but since Android System is keeping the XOOM awake it can't do that. Other than reduced battery there is no other problem with it though.

Under "Included Packages" for Android System in battery usage the following is listed:
PGM System
Settings
Google Backup Transport
Android System
Settings Storage
System UI
Motorola Location Proxy Service
In the main battery usage list nothing is above 3% usage. 5h 31m on, awake for 5h 11m.

Screebl Pro!
I am long time fan and user of "Screebl Pro" By Key Labs. It takes into account the screens orientation and keeps your device (Tablet or Smartphone) backlit. Its great.

I did a factory reset. The problem seems to be about 99% better. There is still awake time under Android System, but it's verrrrry minimal and not even close to the amount of time the display or system has been on. Leaving the Xoom idle for a while to check once again.

I was sort of dreading that. Please check often after you install apps so we can see if there's a particular app that's causing that.

No apps are over 1-2% after being on for 4 hours. 4 min of awake time under Android System. Looks like the issue is solved.

It turned out being Weatherbug. I uninstslled and reinstalled and I'm back to being able to sleep.

After much testing it turned out to actually be having more than one CNN stack on my homescreen. Don't ask me why this causes this problem but it does. Weatherbug seems to be ok. I hope we get Android updates soon to address these bugs.

It's resolved, but not really solved. If anyone notices an underlying application or setting causing this, please be a dear and update this thread?

I just noticed this today. 100% wake time even with long stretches of the screen off. Happened before installing weathebug. I do have 1 CNN stack on my home screen gonna remove it and test.
Very perplexing. You will see much better battery life if the system actually sleeps lol.
Edit: Yep looks like it was the CNN widget. Took it off the home screen and the Xoom started sleeping. Weird.

I FOUND IT! Listen up folks there is a bug in the latest CNN app that was released recently.
When you have 1 or more CNN widgets and you click on a story VIA the widget it launches a service called BangoAnalyticsService or something and THIS is keeping the XOOM awake. Very easy to test, if you go into Applications -> Running Services -> CNN and terminate just the Bango service you will see the XOOM sleep immediately.
Good news is that you can launch stories using the CNN app (NOT the widget) and it will not launch this service so XOOM will sleep.
I've already reported this issue but PLEASE can you all do the same.
Here is how.
1. Make sure you have latest CNN app
2. Have at least 1 widget on your homescreen
3. Launch a story from the widget
4. Go back to home
5. Go to Settings->Applications->Running Services
6. Click on CNN (1 process, 2 services)
7. Click on BangoAnalytics or whatever it is and click on "REPORT"
Put a nasty comment in there for good measure too!!
Glad at least I know what it is. More people that complain, the quicker it will be fixed.
Workaround: Logout of CNN app if you're logged in. Now it appears you can use the CNN app (not the widget) and it will not launch the Bango service that is the culprit. Let me know if you see other issues.

Is there any concern in "Tablet idle" being at like 3%?

Accuweather Bug
I can confirm that the application Accuweather was keeping my wifi xoom awake. Please note that I checked the in app settings for a run in background or update interval setting which it did not have. Once I uninstalled the problem ressolved.

Just did this. This was the cause of my 100% wake times. Amazing though I still got 9hrs of life on the first 50% of my battery weven with constant awake lol.

nope.

Thank you! CNN widget was the culprit for me as well.

Device keeps to be ON and Heats up really bad and drains battery
Mine Xoom after the ICS 4.0 keeps running Android OS @ 90% use and keeps screen on and drains battery within 2 hours.
After hard reset, it seem to be disappeared, but once I've installed some app updates and minimum apps that I had to use, same thing happening.
So far after removing the DrawEverything app, it works better but have to test it and see further.
It is weird, and seem to me some sort of the memory leak causing device to enter into this state.
I will call Motorola and see if I could get any additional information.
Thank you for everyone posting an updates here.

Advanced Task Killer

Does Advanced Task Killer drain my battery even if I'm not using autokill or killing any tasks at all? Like if I just leave it there, will it still drain.
And one important question as well, if a AOL's notification icon appears in the status bar, but I don't see it on the running services list, is the app still running in the background?
Does anyone have bad battery by using WidgetLocker or Weatherbug? I can't tell what is usingy battery

ok first, throw out ATK. the only reason you should use it is to kill a rogue app that has a bad memory leak, or is stuck in a race condition. and you can do this through the settings in any rom, so there is no need for an app.
Second, do you use an AOL app? if so then if it has an icon on the status bar then yes it is running and it has the ability to drain your battery. if its not showing up in the running services, then its not really running. its a neat trick where the app puts a notification in the bar then closes. and when you click it it reopens to where it was.
As for widgetlocker, i used it for a long time and if its setup right it shouldnt drain battery. it all depends on the widgets you have on both your lockscreen and your homescreen. widgets that use alot of battery will do so, while well written ones will not.
anyway, before i get too far off track. if you think a certian app is sucking your battery dry, use an application to freeze it, or just uninstall it and run the phone for a full charge cycle to see if it improves or stays the same. if it gets better, and you used the phone the same way, than that app is the culprit.

Oh sorry I didn't mean AOL app I meant like any app that has a notification icon on status bar. And do you know any good apps to monitor what is using the CPU or causing the battery drain?
And I know ATK is not really needed, but does it still drain battery if you don't use autokill or kill any tasks?

i couldnt tell you if it does or not, but if it does not have a service or process running then its not hurting anything.
as for monitoring cpu or battery drain. i use a program called "System Tuner Pro" it costs money, but it tells you what apps are using how much cpu time in seconds. Any app like that will help, but its not a perfect system, it just helps point you in the right direction.
Last Note, the developer of "System Tuner Pro" is a good friend of mine, so i might be bias in using it

Yeah I paid for the app. Do you know if the Maps app eats a lot of battery as well? Its always in the running services.
Sent from my LG-P999 using xda premium

There is a reason Maps is always running. When an app wants to get location data, it can call on GPS. GPS will return the distance from 3 (or more) satellites, various times, and latitude and longitude. This information is useless to the majority of apps that use it, so they will have to convert it to something useful (like nearby address or a city name).
Now, Google knew this, and instead of making each app that needs a city or address figure it out on its own (which would most likely be a slow, resource hungry process) Google made its Maps program open source. So now these apps can just make a call to the always running maps process and it returns an address, city name, nearby supermarkets, ect...
This app is also responsible for your phone being able to get a rough position without having GPS turned on, it gets WIFI data, Cell tower names, and various other things to figure out roughly where you are in the world. This lets apps like WeatherBug to get your city without ever using GPS.
So thats why its always running, and there is no need to try and kill it ever. Maps is a very well written program, and your better off just letting it do its thing. (if you try to fight it, it's probably going to win )

I do believe I have an answer to this. I found today that, after I finally sat down and finished rooting and flashing and installing and rebooting and updating and all the rest of the happy stuff that equals a much happier user, that ATK did infact drain my battery in an exponencial amount. Prior to that, it was ok. After running CM7, in about 2 hours it drained my battery almost to dead. Now, i work in radio shack, so I've had my phone on the charger and my battery was still dying. So in all haste, remove ATK!!!

I used system tuner to prevent maps from starting up and it doesnt show up in running services anymore. It seems like my battery is a lot better this way.
The only time I really use maps is for gps. I use gps, maps turns on and then when I turn gps off, maps doesnt run in the background anymore. That's the only reason why im keeping system tuner I have no other need for location service.
Sent from my LG-P999 using xda premium

And plus I don't see why Maps always needs to be running. When I need it for location services, then it could just start up then, no need to always keep it running, I really do believe it drains a lot of my battery.

Asleep and wake lock?

Hi Everyone,
I have noticed a couple of posts where people reference that "their phone goes into deep sleep quickly".... What does this mean exactly and does it depend on the kernel you are using?
Also, what does it mean when someone says "a particular app stays in a wake lock". I saw this when some one was complaining about there battery drainage.
How can you tell if either of these things are happening to your phone?
Thanks for all the help!!!

To answer your second question... I use the better battery stats app to see which apps are causing issues.

Ya, better battery stats is pretty amazing, uses root permissions to dig deep. The amount of info us impressive.
It's a $3 app, but is free for xda members. Thread with download is in the main apps forum.
To answer you, a wake lock is when an application or a system operation pulls the device out of sleep to run causing battery usage. Maps is a huge abuser of this (maps does not just mean Google, other location required apps are categorized under maps).
Sometimes they can be stopped depending on what is causing it, but locating them is the first step.

To answer about the deep sleep you can use CPU Spy from the market. It's a free app and tells you what states your cpu has been in since you reset it's stats. Deep sleep being one of the states.

deep sleep on cm10

hi, i have an htc sensation 4g running cm10 jelly bean rom and i wanna know how to put my phone on deep sleep. im on bruce kernel 3.0.49. can some1 please help?

I believe the device should automatically go into sleep mode when not in use. I don't believe you have to do anything for this to occur. Make sure none of your applications are running on there own.go to settings, apps, running apps and see what's running. Leave system apps alone however if other than system apps are running you can close these apps. Just press on the app and a menu will pop up. The running apps other than system apps could prevent deep sleep. Make sure you don't shut down ANY system applications that are running. Those should be fine. Hope this helps. Best wishes.

If you're a little adventurous you can check out the Q&A thread about Bruce's ROM. Skipjacks and Tobitge have put together a list of processes to kill using system tuner (I think). The wakelocks are a known issue and perplexing to say the least. I am beginning to wonder however how big of battery drain they really are... I'm having pretty good results despite them.

does it improve battery life tho?

Yes it would if they could improve the wake lock situation. Check out as above thread suggested, they possibly know of a fix! Also have you considered a extended battery? Extended battery really helped my battery issues. But in this case it sounds like a known issue with something in the rom causing wake lock
This is where your drain is coming from. Check out the fix above. See if it helps.

This only helps with some specific Google Services wakelocks. The Android framework is causing some other wakelocks through the AlarmManager service (Not the same as the alarm clock). These wakelocks have proved very elusive to destroy.
The modifications to the google services framework that Tobitege and I worked out do seem to have some impact on battery life. But if you are a big user of Google Now or GTalk, these modifications are not for you as they break both of those services (mainly because those 2 services were 2 of the 3 main causes of Google wakelocks)
The thing with the battery drain because of these wakelocks is that they drain the battery during sleep, but that drain isn't being properly reported in the battery stats (this is an electrical physics problem related to how a slowly discharging power cell can give a false reading of voltage, not a software problem). So you'll have the phone in sleep for 3-4 hours and it will show no discharge despite constant wakelocks. But us the phone for 10 minutes and the battery quickly drops 15%. In reality it drained that 15% during sleep due to the wakelocks. The battery stats just weren't showing it right away.
Bruce did make some tweaks on 10/27 that have improved the Android inspired wakelocks noticably. But they are still there.

[Q] What is considered normal screen battery percentage for 7.7?

My screen battery percentage is around 70%. I am wondering if that is normal because on a screenshot I saw in another thread, the person's screen % was in the 40s. If it isn't normal, can someone help me with bring the the battery usage of the screen down? (My battery is being drained and I was wondering if it was the issue with the screen .) And sorry if I seem very noobie >_<.

The higher your screen percentage the better it is because it tells nothing else is draining your battery significantly. At 40%, there are other things that are running your battery dry aside from screen.
You could post a screen shot for others to see and advice.

If you're rooted you can always clear battery stats in CWM. Some devices appear to perform better. Also check what's running in the background (processes). Disabling things like GPS can save battery. If you use TiBu, freezing unneeded apps can free up power and resources. If you venture into that, I would suggest doing one at a time to avoid freezing apps that your tab needs running. Google/search forum as I'm sure others have posted their experiences.
Just a few random thoughts....

I notice android media process consume your android battery. I am also wondering about android media and server process in my GT- 6800 with paranoid 2.55. Here are the process that help me out
try to delete all you music or picture files and back it up to you pc
unistall the game and try to install game one by one to see which game will consume your android media process
using terminal emulator to disable android process media. I refer to this site; http://code.google.com/p/android/issues/detail?id=37199
1) have Android SDK installed on your laptop
2) enable debugging on your *rooted* device
3) connect it to you laptop via USB
4) adb shell
5) su
6) pm disable com.android.providers.media/com.android.providers.media.MediaScannerReceiver
It works for me and now I have no media process in system and media server consume reasonable memory. Thanks

My tablet is rooted, but I don't know how to clear battery stats. However, I am currently using Battery Monitor Widget Pro and I see the calibration tab. Once again, I have no idea how to use the calibration thing on this app. And I disable GPS all the time, unless I really need to use it, which is hardly ever. As for TiBu, I don't know what that is. Is that Titanium Backup?

If you have CWM installed then there is an option (from the menu) to clear your battery stats. If you don't have CWM then please download from the "development" section.

Poke around in CWM. I believe it's under Advanced. And yes, TiBu is Titanium Backup.
