A great explanation of the msm_hsic_host wakelock issue by "thracemerin" on the xda-dev forum
I didnt understand the issue previously, but this sheds light on it for me.. http://forum.xda-developers.com/showthread.php?t=2155461
"The msm_hsic_host wakelock is because the 3G modem is connected to the phone as an external USB device controlled by the hsic host controller. When the modem wakes up for any reason (apps sync, location, tower ping, etc...) the wakelock is requested. The problem is that the hsic host controller doesn't go back into suspend mode properly, this is a problem with the kernel. The result is that because the hsic host controller isn't asleep the phone wont enter deep sleep while it waits for the hsic host to suspend.
There is the additional issue that if your signal is poor the operations that caused the wakelock in the first place take longer to complete thus lengthening the time the wakelock is held.
The issue is significantly reduced on WiFi for obvious reasons, all the data is transmitted via WiFi so the 3G modem doesn't need to wake up nearly as often, it still wakes up to deal with tower checks and that sort of thing to ensure that it has voice connectivity, but those events are much rarer.
There are kernels available that attempt to solve this problem, Harsh kernel as suggested by another user has fixes in it along with a lot of other changes, the fixed kernel I'm working on is stock with these changes as well, either should help, it's not possible to eliminate this wakelock completely without shutting down the 3G modem which would of course prevent data and voice use of the phone, but they will reduce the wakelock and may help with your battery life."
http://www.reddit.com/r/nexus4/comments/199bd3/a_great_explanation_of_the_msm_hsic_host_wakelock/
So? How Sony will handle this?
I thought this was already fixed by Google in mainline kernel, this issue is pretty old one.
Remember, this wakelock is not possible to eliminate completely, it's pretty much the synonym to your phone receiving/transmitting any kind of network traffic over 3G. And lot of apps cause regular incoming packets each of which will wake up the phone. That's why to big extent Sony introduced Stamina mode.
Well for me it was busy for 21m8sec on 5h29h of idling. Phone was on WIFI all the time.
Phone was on Wi-Fi, but you don't have Wi-Fi set to be on only when screen on do you? Also, maybe you've enabled "use only good Wi-Fi connections?" As for myself I see noticeable time in this wakelock only when away from Wi-Fi

Try switching mobile data off completely.
Maybe your operator sending you ping packets regularly or something like that.

Just try it out.
Also, if you have Google Now on, switch it off.
Check out wake lock time ratio... My battery is getting killed I run stock 4.3.
Uhm... I've updated my kernel with the latest release from Ziddey (which uses Franco's as a base and adds USB OTG support).
After that I noticed this problem. I've noticed it in the past and fixed it by reflashing a previous version, so I restored a previous kernel but the problem remained.
So, in an attempt to understand what was causing the problem I reinstalled the latest kernel again, only this time not fixing the permissions after flashing it. The problem seemed to be gone. I realized that every time I've had the problem in the past it was after fixing the permissions in TWRP (it asks if I want to fix permissions before reboot every time I flash a new kernel).
Could it be only a weird coincidence?
BTW, I usually never fixed the permissions because I thought it was a TWRP bug/mistake.
I'm doing some tests right now.
[EDIT] P.S. I know it's unlikely that's the culprit of the problem... But...
Hi. I bought this phone for my wife a few years back and recently she told me her battery was draining so I installed Better Battery Stats and found out the same wakelock issue in this post. She is using latest stock rom and the issue happens even if on wifi. I can't seem to find any other information about this issue. Any ideas?
BTW, sorry for necro.

I have been having poor battery life since I got this device on launch day. I just noticed today that my Wifi is constantly scanning even though it is connected. I usually keep Wifi on most of the time since I have really slow 3g at home and the building I work in is like a concrete bunker built in the 1970s so nobody gets very good service in there.
Anybody else notice this?

this is also happening to me, and it is KILLING MY BATTERY!!!! really frustrating.
What do i look for to notice if its scanning constantly? is it the popup that comes up? with the networks that are in range?
i installed a free app called "watchdog lite", and it notifies me everytime my cpu usage goes over 50%, and at this time, i open watchdog, and it tells me "android system" is using 90%+ of the cpu... <<-- this happened EVERY 5 MINUTES when wifi is on. with wifi off, this only happened once in a while, maybe once every couple hours...
screenshow below: the critical battery drop happened when i turned on wifi, and CPU usage was going over 50% every other minute, and i restarted phone...
btw, this wifi issue does NOT happen when the phone is connected to a charger

I've noticed this as well and I believe its also negatively impacting battery life. Its interesting that it would continue to scan while its connected.

Same here..

I see it now....damn never looked there actually. So is basically a bug.
Fixed yet?
I think multiple people (myself included) have confirmed that this was normal behavior - it scans constantly, yet there's no battery drain associated with it.
It seems that whenever you are on that Wifi settings page, it keep scanning constantly. But when you leave the page, it stops doing it that often (or at least doesn't drain the batter.)
You can check that by turning off wifi and still noticing big drain - which would indicate that wifi isn't the issue.
Now, there may also be a bug where this constant scanning actually continues. But like I said, it doesn't do it for everyone.
Use y5 battery saver from the market. It turns on and off with known networks and helps alot.

My wife's is doing this and it is definitely affecting battery. Viewing the battery graph, it does a decline of about 30 degrees with only 3G on and with wifi on it does a treacherous drop of about 50 degrees. I've actually told her to just leave 3G on all the time because it is easier on the battery. Hoping for a fix soon.
Mine scans a lot but doesn't hurt the battery. With moderate use im at 50% with 12 hours on.
Anyone else getting Wifi connecting and disconnecting about 5 to 10 minutes.

Check your wifi sleep policy.
Samsung Galaxy S II
J-u-i-c-e d-e-f-e-n-d-e-r
If you want to try something, change WiFi Sleep Policy to *never*.
It seems counterintuitive, but the bug where Android system uses a lot of CPU uses much more power than setting WiFi Sleep Policy to never as the WiFi is using very little power when not transmitting data while Android system is just sucking up your battery with this bug.
I've tried to search for something like this, but I haven't found anyone with this exact issue. I'm sorry of this has been posted before.
On to my problem, when the phone was new, everything worked as it should have, but a week ago or so, wifi wouldn't turn off during sleep for an unknown reason.
Yesterday I factory reset the phone and didn't have it to restore apps to troubleshoot, and now it looks like this :

change wifi sleep policy at settings.
If I had wifi set to always on I wouldn't really be asking a question, but I should have mentioned that. I've set it to never on during sleep and wifi power saving is also turned on.

emmmm ofc wifi wont go sleep mode when you have set "never on during sleep"
The setting says "keep wifi on during sleep", whereas I've set it to never. If I had it set on "always" it'd be on during sleep. Not the other way around.
When I said "never on during sleep" how could you think that meant that wifi is always on during sleep? Jw.

missunderstood, didnt have near me phone so didnt look at settings how it is called exactly. So then maybe you have some app or syncing enabled which wake up wifi randomly... just wondering
Yeah that's why I factory reset and left it overnight without any 3rd party apps or sync enabled.
I find it very weird and guess I'll just wait and see if anyone has experienced the same and figured it out!
Thanks for tuning in anyway.
If you look at wake and wi-fi on vs. screen on you can see something is constantly waking the phone which is causing it to then connect to wifi. This is a very annoying thing especially when it's still doing it after a factory reset. Depending though you may have some stock app, or account syncing that's waking the phone then it wakes and turns wifi on to use it. If you set up a Samsung Account, Google Account, or dropbox. Many of these have sync settings turned on by default. The Samsung Apps I believe also has it set to use push notifications and over wifi turned on by default. I believe dropbox if logged into also by default is set to auto sync pictures and video with your phone. If you happen to have Facebook it's always running, and by default is set to check for updates every hour. I see you must have GPS enabled for the fact that it at least used it once. It seems like if you have location reporting checked or whatever about wifi networks Google loves to CONSTANTLY do the location collecting. Also if you have your device set to backup with Google it's something that was definitely waking my phone over night a lot more than it needed to be. Also check you maps settings for location reporting/check in stuff. If you've never turned it off it likes to be on by default.
Thanks for all this info, I'm sure I disabled sync options but there might be something left. I'll try this and report after I've left it on tonight! Thanks again

Here is an Xposed mod that fixes the issue (unfortunately, KitKat only for now): http://forum.xda-developers.com/xposed/modules/mod-wi-fi-deep-sleep-t2752947
Hello, I have exactly the same problem on my cink peax. Unfortunately I'm not on KitKat so I cannot try the exposed module. I think some apps wake the phone even when you disable notification. (Facebook, some Google apps also). I tried greenify, it's better now but I still have the problem. So I hope to find a solution.
EDIT : I tried deep sleep battery saver this afternoon and associated with greenify I was able to cut WiFi when in deep sleep mode.
Hello experts,
I have a new Nexus 5x with stock ROM, after I updated android with May '16 update of Marshmallow 6.0.1.
I tried setting the device to flight mode last night, including Wifi off, to see if the battery level is preserved over night. In the morning I saw that battery level dropped slowly overnight, but what is more interesting is that Wifi was still on.
(I don't know why, I can't find the "attachment" section for this post so I use imgur)

go to wifi--> options "advanced"--> Scanning always available. Turn it off. If you can'tt find it in wifi, it will be in location setting.
A couple of things... do you have Viber installed? I know it has a setting within it to override the system setting for Wi-Fi sleep policy. Perhaps it's interfering with flight mode too?
Also, in Settings > Location > Scanning (three dot menu) is the Wi-Fi scanning switched on?
It would seem odd if either of these overrides flight mode but worth checking.
Edit - beaten to it on the scanning one...
Thanks for the quick help. I don't have Viber installed.
I will try the WiFi - location turn off soon when I board a flight tonight
On early releases, there is bug in wifi where it won't go into sleep even if you have the setting for Keep WiFi on During Sleep set to never.
On later releases, they fixed that bug, but now when you resume from sleep, it has trouble connecting to WiFi. Probably that has been a problem the whole time, but it was maxed by the WiFi never goes to sleep bug.
Someone said it (the WiFi not reconnecting bug) got fixed in the most recent release, then later on posted the problem is back.
I got tired of the drama and installed WiFi Automatic which controls the WiFi much closer to the usage patterns I desire.

Hey I wrote the Reddit post about turning off the radio manually. Somehow it did work for weeks and then the bug came back, so the workaround either doesn't work or does not work 100%. I'm pretty convinced it's a wifi bug, as mentioned here: https://code.google.com/p/android/issues/detail?id=196120
It does look that some devs are working on it though.

I eventually didn't turn off the radio manually, but I did turn off wifi scanning in the "location" settings. I was abroad for a week with no cellular service so I was on "flight mode" the entire time. At nights I turned off wifi and checked on it in the morning - most of the times the battery graph didn't show wifi was on, but sometime I think it did.
I do hope Google will fix this eventually.
Not sure when this started but I'm now dropping about 20% of battery per night and when I look at GSam battery monitor it seems to be due to :
- Kernel (Android OS)
- Android System

Anyone know what might be going and what to try to curb that battery drain ? Thanks !
i am having the same problem..... since last two weeks.
Not sure what to suggest, I ended up wiping and restoring with Titanium and it's definitely improved things, something must have gone "wrong" somewhere...
I still find my P2 to be not very frugal (not as much as say my old Moto X) but with the huge battery it's impossible to drain it in a day and I'm never that far away from a power source, so...
Thanks for reply. I dont want to wipe and do restore. If you have to do it only once then its ok but everytime... Not good..
I post the same issue in different forum, will update if i get something..

This?
"The *backup* wakelock is activated once you plug your device into the charger and it continues to manifest no matter what you do because it is stuck in a buggy loop, only reboot will fix it temporarily until you charge the phone again.
Through many trial and error experimentation I finally found an easier fix than rebooting every day.
1- Reboot the phone (just once to fix the wakelock, or the next steps won't work if it's already activated)
2- Before charging the phone, turn off WI-Fi & Google Backup
3- Fully charge the phone
4- Unplug the phone
5- Turn Wi-Fi & Google Backup on again
6- ???
7- Profit!
The culprit is Google Backup, and the bug is activated once the device is plugged into the charger and on Wi-Fi, but if it's turned off before and during charging with Wi-Fi off it'll not be activated.
But if the wakelock is already activated, it won't go away even if you turned backup off.
The Wi-Fi is a strange case, I once rebooted the phone, turned backup off and charged the phone with Wi-Fi on and I had the wakelock. My guess is even with backup off, some logs will still try to backup when Wi-Fi is on (Wi-Fi passwords maybe)
4th day without the Android System battery drain and both my Nexus 6P and Galaxy S7 Edge doze properly now.
Hope It'll help you as it helped me. "

Even in flightmode there no deep sleep with wifi on, tested after factory reset
I confirm this on my exynos s22. There is no deep sleep with wifi enabled.
Untill this issue is resolved,as a workaround, I set a tasker profile to disable wifi and set location services to battery save mode 3 minutes after the screen is turned off. ~ 1-2% battery loss overnight
the wakelock afecting deep sleep is : qcom_rx_wakelock (over 1100 times/h)
Seems only S22 affected?

light doze, didnt have enough time to enter deep sleep today (only flashed it this morning)
It should enter deep sleep in few min after screen off (besides if some activity on tho)
update:
The issue is not fixed yet. 28minutes deep sleep overnight with wifi on.
turned off everything that could cause deep sleep not triggering
turned off wifi, left the phone for 13 minutes -> 10 minutes deep sleep
untill a samsung fix is coming, the tasker autowifioff profile will stay not sure any developer can fix this without rooting the phone
EDIT:
I am getting different results between battery historian and betterbatterystats
Attached photo of historian during the night. Full doze (blue)
Battery still drains a lot in standby during this time. Its good without wifi
reported qcom_rx_wakelock is at 600/h
I switched to "Naptime" app, set wifi off when screen off. Lost 5 % in 8 h sleep
hopefully samsung can fix this in a future update, april patch didnt make the cut for this one
WiFi issues with SIM installed slot1 but not when installed in slot 2
I am having a WiFi issue with a 908E/DS when a SIM is placed in Slot1, I have Issues connecting to 5GHz WiFi sources. Once I place the SIM in slot2 it works flawlessly. Had a similar problem with S21U as well. I have tried with an A73 with 2 SIMs...

Tested, did not help, still no sleep with wifi on
might be a multicast issue on your router.
mine actually goes to deep sleep but still the drain is higher than on my previous s21
