Google Chrome - suspend_backoff kernel wakelock - Galaxy S III General

Just a quick warning, since installing Google Chrome on my S3 I'm constantly having a suspend_backoff kernel wakelock. This wakelock isn't in BetterBatteryStats untill you launch Google Chrome and exit it. Turn of your screen for half an hour or so and check back in BetterBatteryStats, you now will see the suspend_backoff kernel wakelock for the whole screen off time. Taken me a whole Saturday to find out it was Google Chrome causing this issue, so just a quick warning. I don't know if you guys have the same issue, but it's worth a check because it kills your battery.

Yes agreed...
I too got this bug n after removing Google Chrome everything seems back to normal...
Thanks for sharing this information..

I had this exact same problem with Chrome Beta, but the latest version (the first non-beta) seems to be fixed. No more wakelock issues and battery drain.

I have the same issue with my SGS2.
Currently I'm on the latest google chrome, the non-beta one, and I still have this issue. Completely drained my battery overnight.
How do you guys know suspend_backoff is related to chrome?

A day of testing and deleting every app to exclude every possibility. Running Chrome results in the wakelock, deleted Chrome, ran every other app on my S3 and still no wakelock. Installed Chrome again, ran it and tada wakelock again.

Same here, battery starts reported suspend_backoff to have kept the device awake for 5h. Drained my battery overnight. In Samsung's taskmanager google chrome was the only active application. As soon as i killed it the wakelock was released.
Shouldn't Chrome automatically close itself?

No issues here. Still losing 4-5% overnight (wifi on)...

Oh I hope this is the source of my battery drain. So stoked on this phone except fo r the battery life!

Google Chrome is kind of crap now, the final version is pretty bad, not smooth and often fake hanging your phone.
Abandon it now...

Glad I found this thread. I was having the exact same issue on my galaxy s2. I could not figure it out until I found this thread. Thanks!

Yep I have now uninstalled Chrome to only leave the stock browser.
Battery was kind of fine but would be happier with extra juice now !
I will retry Chrome after it has been updated ...

Yep that was it!
Went from losing 30% overnight to 4% last night.
Thanks man!

Has anyone opened a bug report on this issue? I would but I can't find any actual proof that chrome is causing the wakelock (other than it goes away when it's uninstalled). Better battery stats doesn't show much other than "suspend_backoff".

not happen to me..with chrome installed

Plus it's happening with some and not with many.. However, I'm not installing Chrome again when there are so many other options available.. Never been a Chrome fan on Desktop too..

I think I have found the problem with chrome. If I don't set up book mark sync then I don't get the wakelock.
UPDATE:
After running tcpdump on my router I can see that my phone is contacting google every 4 minutes with chrome sync enabled. This is probably frequent enough that it causes suspend_backoff from preventing the phone from sleeping.

I don't have bookmark sync and still managed to get it. Once on my SGS2 and once on my Note.
Hasn't happened since on either device after I stopped running Chrome (still installed though).

Calendar eating the battery.

Hey guys wondering if its just me...
My battery is only lasting about 5 hours. And when I check the usage it turns out the calendar has used 62 % of my battery.
Does anyone know why this might be? I have a logcat which shows it tries to connect and fails but I don't know what the logcat means.
Any help?
sent from beyond...
Calendar ? Thats strange . The only thing that drains these beasts is the 4.3" display.
Sent from my Desire HD using XDA App
You could try disabling automatic syncing?
actually the only thing draining these things is the 3g. switch it back to gsm only mode and you will get nearly double the usage out of the battery.
pity we cant use the 2g toggle yet that is only available with the cyoagen mode

We can
Cyanogen for the DHD is now in beta.
I had this problem a couple of days ago. Noticed that battery was draining much quicker than normal, checked battery status, and calendar had used over 50% of the battery and had over 4 hours of CPU time when normally it is only a few seconds. Rebooted the phone and it went away. No idea what caused it though.
My 3g is no problem. I guess cus I get very good 3g and hardly drops it doesn't drain my phone searching for 3g signals. It's the display on mine even tho I adjusted the brightness

Same here. Asked HTC with no success. They advised a hardresed... After hard reset my calender problem was gone...

I recommend installing Juice Defender. Cuts off data connections when phone is asleep, then opens for a moment every 15 mins to sync. Saves me TONS of battery.
I had exaclty same problem. All you need to do to fix this is clear data and cache for calendar, calendar storage and calendar widget.
Since I did that (4 days ago) my calendar app works great
Just cleared my calendar cache and stuff, having the same problem as you can see:

Though it does not always happen with my DHD, I have seen similiar results to the screenshot posted by muppet0000.
My calendar is constantly draining 20% of the battery. I really dont think this should be the case. No more suggestions though I'm afraid.
I have the same, but my battery life is good
Sent from my Desire HD using XDA App
Interestingly, it uses 20% of the battery if I ever use the calendar.
i seem to have found a solution. i have taken off the facebook sync to calender. this seems to have stopped the problem. my calender is again 1% of my battery consumption.

I think mine's related to Facebook syncing contacts.
It seems to start syncing them, but just keeps going...
I've just cleared data on both Facebook apps. We'll see if it helps.
Hello, mine does the same, I am using SeePU and CPU is 100% usage from time to time for about 1-2 hours (I check it once in a while). Installed SystemPanel to check the process activity and it's com.htc.bgp which is using about 50% of the battery (16h25m of CPU usage).
When going to the Settings-->About phone-->Battery-->Battery Use, for a flash of a second the process com.htc.bgp appears on top, but then changes to "Calendar" and uses 40-50% of the battery.
I use as calendars the exchange e-mail and facebook (used only for birthday reminder sync). The problem appears also when I remove the exchange server so it seems this is caused by Facebook. Unfortunately, I can't find a solution for removing only the calendar (I can live without birthdays...) but still I need the contacts synced....
Any solution found so far?

[Q] Name this wakelock

Hi.
I'm getting some weird battery drain on my N4. I'm running a pretty raw collection of incomplete things right now, so I know mmmv, but I'm trying to track down which program or service is throwing this partial wakelock. It comes up as "Google Services" in the battery settings and as "*sync*/com.android.browser/com.google/[gibberish]@gmail.com" in BetterBatteryStats.
See the attached pictures. I'm on a more or less stock early kitkat rom from PA, 0-day GApps, and ART.
I bet this drain will go away when some or all of those are updated, but I'm otherwise very happy with my phone as-is so if I could solve this without reverting to JB or Stock that'd be great. If I can't, I might try Dalvik again and see if it helps.

What ya still doing on the AOSP ROM? Get yourself a factory image and then tweak/flash away! its your 'services'.
If you don't want to change when I didn't as well (also used AOSP 4.4 for a while!) I just backed up everything on PC and factory reset and wiped data. It then resolved my wake lock issues, hopefully it works out!

Go to Settings -> Location, choose Battery Saving or Device only. In addition, do you use Google+? If no, disable or uninstall it. Reboot the phone and monitor battery usage to see if still draining fast. If still, try to clear cache and dalvik cache in recovery.

Sorry for the slight necro.
I am having this wake lock frequently myself, doesn't seem to take a huge hit on the battery but does keep phone from deep sleep.
I looked all over the settings in browser app, couldn't find sync, can anybody assist in location.

Nobody else has any of these wake locks?

[Q] LG G2 Battery Drain

Hi,
I have had my G2 for a few months now and have taken all the usual battery saving measures. On a normal work day, I can leave work with approx 60% battery left. No sync and no apps running in the background. I use task manager regularly and Clean Master to keep my battery lasting as long as possible. However, for no discernible reason, my battery has started running down at an alarming rate today. When i look at my running apps the list covers almost every app i have whereas normally it might have just a couple. I haven't downloaded any new apps or updated anyand my OS is up to date. Am i the only one experiencing this?
Thanks
Assuming you've already tried setting Location Mode to Battery Saving instead of High Accuracy, check to see what's consuming most of the battery (Settings--> Battery; tap on the battery icon).

If the problem is not to do with wakelocks, then it is probably due to a badly calibrated battery. Download two apps: advanced battery calibrator and batterycalibration. Follow the instructions of batterycalibration first. Then the next day, charge your phone to 100 percent, then follow the instructions on advanced battery calibrator.
That should fix the battery life.
However, if it is wakelocks, download wakelock detector from the play store and screenshot the cpu wakelocks page please. Then, post the results on here.
Hi, I have location turned off completely. Battery use says my screen display but that is set either to auto or 50% today, I normally have it on full and last the day easily. It's been great up until today, for some reason all the apps are running in the background within seconds of killing them all off.

Hi, I'm going to look into wake locks, not heard of them before. What would cause my battery to go from being great yesterday to badly calibrated today?
Sent from my LG-D802 using XDA Free mobile app
Maybe some apps you started toda are draining lots of battery since there is always google/whatsapp or facebook and many other apps keeping synchronizing in the background. I dont know or you have facebook but i had that app and that drained alot of battery on my nexus 4.
Uninstall clean master and task manager, this apps draining a lot of energy. Make a hard reset after this.

13800000.decon_fb Wakelock

hi ,
Long shot...... "Facebook " app ?
.I have read ( quite a few threads in past) that Facebook app, can cause wakelocks and battery drain etc etc .
But then again i stated.."long shot "
good luck
I uninstalled Facebook completely, however the wakelock is still there. As seen from the code that I referred to above, it is not connect with 3rd parts apps. It looks like that it is connected with Samsung staff. Can anyone tell what that code is for?
Just ignore it.
It's a wakelock that is taken when you turn your screen on. The count is how many times you turned your screen on and the time is your screen on duration. It has zero effect on battery consumption.

Thanks AndreiLux. I have my doubt about this wakelock 13800000.decon_fb as well. After a few googlings, it brought me here and I have the answer.
T
Facebook AppManager wakelock faulty
I just googled 13930000.decon.fb on Note5 abnormal wakelock and came here, now I know it's equal to SOT (thx to AndreiLux) but for those about to complain about abnormal battery drain :
Facebook consumes battery heavily, "and specially" when it is installed as system App with com.facebook.appmanager beside of it.
Uninstall/freeze com.facebook.appmanager or debloat Facebook totally, reboot and install it again from any market (Google Play is preferred).
It will still be draining but way much better than before
I don't think it has anything to do with screen... i get 1 hour and 30 minutes kernel wake with this on a 5 hours standby time during the night... and FB in hibernation mode by Greenify module. for now it's a mystery to me but just to satisfy my curiosity I'll see what can be done.

Battery draining apps?

Hi all,
Like all of you i am conscious of my battery on the S10+.
Considering it is a 4,100mah battery you would think it would last a minimum a day and a half however with me i only get a days use out of the phone (by merely doing some browsing, youtube and whatsapping, nothing intensive). I've noticed that even if i use the phone considerable less in one day vs a heavy intensive day, i still get the same usage - around 24 hours.
I have turned off AOD, Location, have Sync on, FHD display.
In theory if im not using my phone, my phones battery should be depleting very slowly however this does not seem to be the case.
So to me it looks like something is draining my phone (i've had the S7, S9, with the same problem). I've reset my phone, not restored a back up and still the problem persists.
Looking at my battery usage recently i have seen Google maps being the highest used app (however i have location off and don't use the app and even have forced closed it).
Has anyone else noticed this? anyone have any recommendations?

Thanks for this - I have been following this thread quite closely but the reason why i made this separate thread is because i believe after all my personal testing it seems to be app related - Im thinking specific to google apps with all their background services.
Just thought if anyone had isolated this like me and if they had any fixes for this.

Wow that is actually amazing results - which google apps have you disabled and how (i.e. just uninstalled them?).
Also the only google app i only would like to keep is google maps - as i use this when driving here and there.
Last question - you basically have 10hours SoT over 2 days. If you used your phone less, do you believe your phone battery life would extend to 3/4 days even?
