Syncloopwakelock? What is it? - Samsung Galaxy Nexus

I noticed on the better battery stats app that the top of my wakelock list is something called Syncloopwakelock. It's been active for 41 minutes and has a count of 2317!!! It also accounts for 87% of my device wake time.
What the heck is it?

Hi, I am getting the same thing on my sensation running ARHD 6.0.3. My battery isnt dropping below 20mA when its sleeping. Did you manage to find out what this was?
cheers

Nope. I was never able to find out more about it and it continues to be in my top three wake locks regardless of what I do.

I'm wondering the same thing, On my GNex SyncLoop has a count of 1835, but only says 1s for total time. It is the highest count of wakelock items and currently my phone is at 75% awake, and it's been sitting on my desk screen off almost all day.
This is killing my battery and just started recently.

Seeing a far amount of wakelocks here from this. SGS 2 pre release build 4.0.3

Only seeing this since I upgraded to 4.0.2... so much for better battery life over 4.0.1!

Hi, are you guys running custom roms? I updated my version of ahrd to 6.1.2 and now that wake lock appears waaay down in my list.
I also realised that my main battery drain was the radio trying to hold onto the 3g connection in bad signal areas, ie at home. If I manually switched to GSM I saw an amazing improvement, so now I use a great app called toggle 2g to switch to2g when using WiFi or sleeping Search for it in the forums. Works with locale too although I find that to be an over zealous wake lock itself

Battery life just terrible, need since help plz!!

As title says guys, I don't no why but my battery life is just really bad since I moved from stock 2.1 Rom to custom ROMs :-(
Is it my phone? I can't work pig wot it is. I checked the battery usage #*#*4636*#*#) and it seems the Android system is using A LOT of it. I tried charging with phone off, clearing battery stats, not overcharging, but just can't resolve this issue.
Also, I have sync set to update manually and have mobile internet off always, only on wen needed. Same with WiFi. Screen is on auto and time off screen lock set to 30 seconds
I am using OpenDesire sense Rom
Any help will be really appreciated.
Thanks

I could feel WiFi siginal of 2.2 is much better that stock 2.1,
I suppose that the better performance will bring the fast battery drain,
if your custom ROM support WiFi N mode,
that really makes your battery life short that before.
I have the same problem and same settings as you. I read on other forum that people who updated to official 2.2 have even better battery life.
I cant even squeze 20 hours out of my battery :/
You guys should always post what ROMs you are using...
Opendesire 3.3, its the same with defrost.
i also had really bad battery life on those 2 roms
even doing nothing the phone would just keep dropping
go to official froyo 2.2
neophye roms for me have amazing battery life = 48 hrs..
Agree with cygnet

Check if the phone goes to sleep correctly. Spareparts > battery usage: other usage, since last unplugged.
I had the same problem, until I found out that the phone was not going to sleep. (running and screen on percentages were way off. Almost 100% running and a lot less for screen on.
update to the last radio
I found that after forcing everything to install to SD card my battery life plummeted. There were apps/widgets that should have stayed on the phone. Once I moved these back, battery life was back to normal.
I use Systempanel to see the battery drain graph and could see a pattern to it.
Same issue here, Will try Neophyte tonight
Using this rom http://forum.xda-developers.com/showthread.php?t=741663, and it's fantastic! However batt life on .08 and .20 radio is a shocker. I watched a 1 min trailer on youtube, in and out and I lost 4% battery. Before with OpenDesire I'd be shocked if the battery percentage even twitched slightly.

I use Defrost 1.5a and I just use about 2% every hour when the phone is sleeping, and that's with auto sync and mobile data enabled. (disabled it's 1%/hour)
Always underclock to the lowest mhz when the screen is off using SetCPU and when you do use your phone make sure the brightness isn't too high.
I could make a whole list of tips, but I'm sure you'll find more than enough of those on the net.

I may be dumb but how do you force your phone to go into sleep once screen is turned off ?

When your screen is off, your phone should automatically go to sleep. Sometimes widgets or apps keep this from happening (like the music player), making it use battery as if you are constantly working on it.
How I resolved this issue was to find out what app or widget caused this. I ended up starting from a fresh reset, installing first all apps I really use (calendar/message widgets, powerstrip etc.)
I tested by installing an app, rebooting (or sometimes not), check the running time of the phone, turning screen off, and check again in 5 minutes. The phone should go to sleep in about 30 - 40 seconds. I am telling you this, because most apps causing this are widgets/apps running constantly.
However, I found in spareparts also that 'settings' was taking alot of usage time in usage statistics. A simple reboot did the trick from here on. But I am guessing I had installed something which made some app not close properly..
Maybe it is better to have a task manager/killer for these situations.
Running and Screen On percentages should not have too much of a difference if your testing and not using the phone while screen is off (music, bg stuff)
You could try juicedefender, it helps improve battery life by disabling unneeded connections while the phone is not in use

Battery Calibration didn't change anything!!!

Running stable CM 6.1 with cm kernel & followed the steps of calibrating battery & my battery lifes still horrible, currently 1 hour after calibration and already down 2 70% from being on internet & a few texts

have u got spare parts? open it up and look at battery history and the running vs screen on time.
they should be the same but i can almost guarantee that your phone is still running whilst the screen is off. you need to find out the app which is keeping a wakelock on ur device and delete/change its settings
Ok thanx..will try this

Sorry for the noobish question, but can I compare the two. I went to spare parts and could not see where to compare screen on time vs running.
I recently tried to calibrate y battery, but sinse my screen does not shut off on its own as before. I've aleady checked the screen timers and all is as it was before.
Right now I am @ 4.5 hrs since I unplugged and I am sitting @ 76%, with little use...kinda sucks!!!!

What kinds of widgets do you have running in the background and how often are they pulling data?
Also, how many days have you been on CM 6.1? I upgraded from RC3 and my battery life is much improved. The first two days it was eating a lot as it 'calibrated' itself but now I can easily make it through a full days use with about 40% to spare.
I adjusted my background widgets and how often they pulled data and this really helped my battery life. Also, a poor signal can have VERY ADVERSE affects on battery life. For example, I work in a prison where cell phone reception is awful. If I am at work for 3 hours and leave the phone in 3G mode, I can easily go through 30% battery while the phone tries to find a signal...
Any idea how long will it take the batt tocalibrate???? I did the recalibration process on thurday night, and my battery sucks now.
I'm sitting on 49% only 4 hours unplugged. Before I was getting somewhere around 55-60% at this time interval...
Any ideas?

Alright boys try this. I got over 2 days worth of lifetime with this set up.
-Download SetCPU
Set your profile to 245/245 screen off with priority at 100%.
-Turn brightness to 0%
-Turn GPS off (Go to Settings->Location and Security-> turn off all that GPS crap
-Leave 3G off until you actually need it, then turn it back off after you're done with it
-Leave bluetooth off
-Don't have garbage widgets lying all over the place on 7 homescreens. I only have like 5 widgets spread out on 2 homescreens.
Are you guys running CM 6.1? Cause I am.
Did you guys overclock?
Thank me if it worked out for you =P

Convolution Thanks for the reply, but im more interested in getting a few more hours but with certain level of freedom. I am not all that interested in switching things on and off every time I need them, but I understand what you mean.
I'm looking to get 16 hours of moderate use...that should be plenty. I currently turn off wi-fi and gps since I seldom use gs, and wifi is governed by a profile manager, and it's on only at night.
but setting connection down to 2G, and killing all screen brightness renders the device (IMHO) useless. Also, SetCPU @245 100%, would really hinder the device.
I am running CM6.1 Stable and I am running OC'd @ 1497, but on "On Demand" profile, so to use only as needed.
I still have to try Pershoot's kernel, I think I will flash it tonight to see what happens.
I am also experiencing some oddity with my screen time-out feature...it's not working.....my screen refuses to turn off by itself, I have to lock the device physically for it to take effect....not sure what changed...but the regular parameters are set properly.
I'm getting 2-3 days with the stock WWE ROM that came with the phone. Brightness is set to Auto, but I keep GPS, BT, WiFi and mobile data connection off until I need them. Other than that, I talk about 20-40 mins/day, send out a few texts, listen to the radio, read my feeds and e-mail - pretty much everything the phone was made for.
IMHO, the "calibration" is bullcrap, it's just an impression that it lasts longer afterwards.

Basically the same setup I have in terms of connectivity except for data.....does it really have that much impact on battery life?
What would I missing if I decide to turn data off?
Thanks!
Huge impact. Try it out for a day or two. Or just install Juice Defender, which disables it while the screen is off, turning it on at set intervals (like for 1 min every half hour) to let it sync.
Thanks Keinengel....I'll look up Juice Defender...sounds like the right thing!
i get atleast a day and a half out of my phone and i had it for about a week now. best battery ive had for a while now.
Wow guys...installed juice defender and pershoot's kernel, and only gone 1% in about 2.5 hour....I'll report again tomorrow

Wifi drain or just normal?

Hi,
New to the note 2, not new to being a flashaholic. Being very tame atm and only using stock rom (rooted) with no Cwm.
Strangely I get about 10% drain overnight. Got better batt app but doesn't really show much except wifi is/was on.. And this audio_out_2.
Is that normal on stock rom? On the dhd it was more like 1-2% on experimental roms

Disable stuff manually or use Juice Defender Ultimate (3.9.6). I use JD and never turn anything of manually.
I do have sync on. I guess what people are trying to say it's pretty standard on stock rom and I'm in need of an awesome custom rom to flash?
I used jd ages ago but configuring is a bit of a pain.. I may try it again till awesome roms comes out.

Check you applications, I have 90 apps installed and only have 0.5-0.6% per hour while sleeping with sync on.
Tonight, for example, I left wild blood downloading the last 200 mb it needed.
It took like 5 minutes, then I woke up and I noticed that it kept the device awake for 6 hours even after finishing the download, Battery went for 50 to 43% in 6 hours..
Custom roms won't make a great difference.. Maybe removing some bloatware will do, but you can stay on stock imho.

Just a question, do you, by any chance, have SIM plugged in? I observed quite higher power drain (overnight) when I did not have SIM inside.
Yeah, I have sim in at all times.. Erm apps wise, I've not added any new ones before my upgrade so I guess if there is an issue it would be some bloat apps? I tried to freeze as many as I dare using tb. (well, I followed the script of apps to delete on the other thread).
What app did you used to find what apps drained x amount per hr? That seems like a clever one
Sent from my GT-N7105 using Tapatalk 2
Yeah, I have similar experiences. My phone drains around 10% overnight with no apps in the background and wifi off.
So what I'm doing and it seems that it has marginally helped is:
1. Turn off Sync
2. Turn off Notifications from Email accounts as these come in all the time even overnight and the notification process and the Blue LED will drain the battery
3. Decrease screen brightness to around 40%
4. Turn on wifi only when needed
5. Disable some of the apps I don't use (Chaton, Yahoo Finance and Yahoo news, S Suggest and Samsung Store, etc)
Now I get about of 1 1/2 day of regular use.
Think I found the culprit..
Has anyone got motion feature turned on? There's that sneak wake function ticked on mine as default, I switched that off and I only got 4% drain overnight.
Perhaps others may want to give this a go and see if it helps?

4-5% per night is what I see on my GT-N7100 (intl), with Wifi on, BT off, GPS off, NFC off, Sync on.
I got Motion on though, with following features: "Tilt to zoom", "Palm swipe to capture", "Palm touch to mute/pause". I am not sure which one is supposed to be "sneak wake" one .
But now, when thinking about it, I realize I do not need any of those, so I am going to turn Motion off completely to see if it has any impact.

13% is ODD. Something is sucking up your battery.
Expand your Android system and post the Screenshot - want to look at cpu wake time.
What is your setting under - Advanced Wifi options - while asleep - wifi on or off ?

To be honest I have done so many tweaks to help with wakelocks. It is definately not an app but the standby time is sooo much worse on my Note in comparision to my HTC One S. I'll get about a day regardless of screen time. On my One S I'll get 2 days with the same screen time and with the same apps.
The only thing I can think of it being is that mdm_hsic kernel wakelock. Have no clue what to do about that though, and it's clearly a Samsung/Note 2 bug given that the HTC doesn't have this sucking away the standby time.

The thing is, I also have the ebay app on my HTC and it doesn't suffer from this problem. The HTC is 4.1.1 though so I'm guessing this is either a Samsung problem or a 4.1.2 problem.

hi,just a few pointers to think about ....?
i am on stock 4.1.2 not rooted ,and my avarage battery drain overnight (10/11 hrs +) is 2%..or ..3 %.
i also have a note8.0 and battery drain is normally 1% in standby mode overnight (10/11 hrs )also on 4.1.2
lucky ? no i don't think so .
(maybe i got my all "tweaks " right..no ?)
just a few pointers (things to think about, why others get better results and others not,in this case on 4.1.2 )
good luck

Do you have any Battery manager apps installed? I had one that constantly pulled WiFi status and since I have WiFi disabled when outside of home or work it kept on turning it on/off and drained my battery. It was my error for configuring it wrongly, I admit but still, that may happen without control.
Check Wakelock Detector, click on this:
Awake.............................Statistics since..............................Deep sleep
bar after night of rest and post statistics that you find there, The most interesting is a difference between Screen-on and awake times. If your phone is awake much longer than it has it's screen on then there are some processes that keep it awake and drain battery.

Wifi does seem to be messed up on this phone. I find, on standby, it causes more drain than 3G does. Usually something like 10% - 15% overnight.
This is not right and something is seriously a miss with Samsung. My HTC running the exact same apps does not have this problem. You shouldn't have to turn wifi off as opposed to 3G to get better battery life.

Are you thinking about some hardware problem that causes wifi to use more memory than usual? Like higher voltage or something? Because that is not very probable. I think there is some app there that is using wifi, high power usage happens when wifi is performing scans is being turned on or actively transmiting data. Please use wakelog detector to find what app is causing kernel wakelocks and from there we can find a real culprit.
I does not have to be malicious but may be an incompatibility between hardware and some software, one that works well on HTC and not on this Samsung model.

No I don't think it's hardware.
I also don't think it is an app given what I have observed with wakelocks and deep sleep. I have made many adjustments to the phone and I'm clued up with wakelocks and the like and this doesn't seem to be a wakelock issue.
I have even assigned a static ip and made tweaks within my router but it hasn't helped. There seems to be a strange way this phone handles wifi and it is causing unnecessary drain.
In regards to Kernel wakelocks, it would appear something called mdm_hsic is causing lots of wakeups and more standby drain than it should be and this does not feature at all on my HTC. This is not related to wifi, but I'm pinning the general crappy standy drain im getting on this but there doesn't seem to be a way to get rid of it.

No I don't think it's hardware.
I also don't think it is an app given what I have observed with wakelocks and deep sleep. I have made many adjustments to the phone and I'm clued up with wakelocks and the like and this doesn't seem to be a wakelock issue.
I have even assigned a static ip and made tweaks within my router but it hasn't helped. There seems to be a strange way this phone handles wifi and it is causing unnecessary drain.
In regards to Kernel wakelocks, it would appear something called mdm_hsic is causing lots of wakeups and more standby drain than it should be and this does not feature at all on my HTC. This is not related to wifi, but I'm pinning the general crappy standy drain im getting on this but there doesn't seem to be a way to get rid of it.

mdm_hsic is related to Modem part, you may try different modems (be mindfull of efs problem in newer firmwares), also try to enable/disable "fast dormancy". I think you could test that by selecting "GSM only" and observing.

Thanks for the reply
I have tried different radios in the past. If that's what you mean?
I've also tested around with fast dormancy (it is currently disabled)
My network only works on 3G and has no 2G coverage. It is purely a 3G network and therefore GSM only will not work. This problem still persisted when I was on a different network though and selected gsm only fornthe majority of the time.

Yes, I was talking about radios.
Have you ever tried changing CSC file? Full, four part flash in Odin, not only PDA?
What method did you use for modifying fast dormancy setting? Because the correct one includes full factory reset when changing CSC. Anyway fast dormancy would be a problem only if you used 3G network for data.

Nope have not tried changing the CSC.
The method I used for fastdormancy was with that app in the marketplace than allows you to toggle it on and off. I'm not sure if fastdormancy is linked the mdm_hsic though, to be honest.

[Q] HELP cell standby huge battery drain[tried each n everything prb still persists]

hey guys...
i have tried everything to stop the battery drain
switched to many different roms
under-clocked processor to 768mhz
set a black wallpaper
brightness set to minimal
did battery calibration
switched of all background processes and made sure no location seeking programs works.
used CPU spy, the cell does go to deep sleep
tried juice defender and deep sleep battery saver
but nothing seemed to work
phone locked on full charge drains 40 to 50% in night without using.
then after a few days later i restored everything and opened airplane mode and I went to sleep, in the morning the battery didn't went low a single percent. battery health is good as works really well on airplane mode.
i have low signal issues but i get text msgs and calls with no problems at all, and my explorer and s3 seems to perform well
my all type pf connectivity is off example: location access WiFi Bluetooth etc only gsm is working, i manually selected the network and set it to gsm only rather them auto from *#*#4636#*#*.
what shall i do??
i searched and tried many things from the internet.
i really want those calls i cant always be on airplane mode, the problem is 200% of the antenna draining juice to get more signals. please help.
is there any way to stop the battery drain or restricting the antenna to consume less juice?
PS:using cm10.1 by nightly version:19 Aug 13.
anyone??
one thing more i installed better battery stats it says
no or unknown signal
no data connection
and it is running continuously like since i installed betterbatterystats.
where can i get this bug?? or disable this service??
please give a detailed explanation.
There are a few good apps to try I use
battery mix (I think this is one of the best) and wakelock detector both from my the market.

i am thinking about changing my radio... doing research n stuff... lets see what happens.
as it would solve the signal issue and battery all together.

bro if ics solves the problem of battery drain due to low signal then y not... i will surely try...
i dont get a single percent drain on airplane mode the problem is surely network sucking it down... yesterday it went 100% to 48% in 8 hours in deep sleep n no wakelocks[betterbatterystats] :crying:

Battery drain
I´m having same problems with my DHD, currently im using 4.2.2 Samsation (was it named like that but anyways 4.2.2). Without using phone it still drains 40% in few hours.. I got replacement battery from eBay and thought that would help but didnt help at all. I´ve tried different roms but would like to have newest roms without battery draining so much, so could someone share how to get it better?
And about changing radio, was there a possibility that you may brick ur device if installing wrong radio?
Thanks already!

and regarding the radio if u do it right and reasearch a little u wont brick it for sure. got my radio from here:http://www.icsforums.com/forum/showthread/26951
downloaded this zip and replaced the radio.img within the zip from above link.

put the file on sd card root
booted in bootloader
that did the job.

Have you tried looking at Better Battery Stats to see if it's an app draining your battery?

yup there was nothing, no wakelocks etc i even underclocked my processor to 768mhz... the thing is the signal reception cause when i turn the cell in airplane mode and leave it over night the battery doesnt goes down a single percent. it acts solid.
i get around 18 asu signals at my place i check it from *#*#4636#*#*
but the thing is i was using an HTC explorer before switching to desire hd and with the gsm mode(no airplane mode) the battry stayed solid like the desire hd one with airplane mode(didnt dropped a single percent) at the same house same place.
dont know what going on.
