Wifi on/off constantly in deep sleep

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 :

}
why does this happen?
Everything stock, but if rooting could fix it, I'd do it in a heartbeat.

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.

Battery Drain - Android OS wakelock

I have tried doing partition wipe cache and disabled most apps under auto start manager, unable to figure out what is causing this issue
I have no other issues on Asus Zenfone 2 and it is probably the best Android phone I have ever used, just this battery drain issues is irritating.
Lot of Zenfone 2 users have logged this issue on Zentalk forum but Asus support seems to be clueless about it, recent firmware update also failed to address this problem.

I think it depends on wi fi...
When I'm at work ZenFone connect to various AP and the battery drain is heavy....
But when I'm at home the battery seems to be normal, I can finish the day with 20% of battery from 17 to 21.
I see the battery is longer on 3g/4g than when i'm at work on wi fi

I think Zen Motion in settings specially touch gesture is one of the causes for battery drain issue...
Sent from my ASUS_Z00AD using XDA Free mobile app

Probably...but when I'm on 2.17 I don't see this battery drain....and I always have gesture, double tap to wake/sleep and zenmotion all gesture.
I see the battery drain increased when Asus have changed power profile

'Wifi Scanning always available' may cause battery drain. Recommend to turn off in not needed. To do this go to Apps/Settings/WiFi Settings/Advance Settings(menu in upper right corner)/Scanning always available/ turn Off. If battery still draining, recommend updating firmware to latest version and then performing a factory data reset. Please ensure to back up all important data as this will erase all data.

Hi Frank,
Regarding the Wi-Fi always on thing... Whenever I turn it off of always turns back on automatically.... Any advice.. I already am on 2.19 BTW..

Apologize for the delayed response. Strange, it shouldn't turn back on automatically. After latest firmware is applied, recommend doing a hardware reset including wipe cache partition. For hardware reset/wipe cache partition instructions please see the following: http://www.asus.com/us/support/FAQ/1011956/

Frank have you heard any rumors on if asus is working on the 5.1.1 update. The issue of Android us chewing up battery is a widely known issue for lollipop 5.0 and it impacts many different devices. Every thread I have read regarding this specific issue states that lollipop 5.1.1 resolves this issue.

Pathetic battery back up on ZenFone 2, hardly getting 3 hours screen time these days
Sent from my ASUS_Z00AD using Tapatalk

My battery stats still reporting WiFi use when I have turned WiFi off and disabled always scanning. I don't get it!?
Edit: just figured this mystery out. It's because I had location set to high accuracy. If you set it to high accuracy or battery saving it scans WiFi even when WiFi is off. Put location to GPS only for the last ten minutes and voilà - no WiFi use in the battery stats

Spoke to soon, WiFi came back again on battery stats!???

Do you see any major results with that application?

I read a lot about awful battery and screen on time before buying the zenfone 2. Surprisingly though with a bit of tweaking this has been one of the best phones I've owned in terms of battery life. I could have easily gotten 10 hours of screen on time i believe if I stayed in an area with stronger reception and turned off some background services like GPS. Here's some screenshots for anyone interested

I'm using the 551 with the latest .22 update. I'm not sure *exactly* what I did to fix the idle Android OS battery drain but I have underclocked to 2.0ghz, zen motion stuff is turned off, GPS is set to battery saving mode, all the stuff under Google settings >security is turned off, Asus cover off, detect battery draining apps in battery settings is off (its not very efficient as it just checks what is running in background, regardless of battery usage) and some more stuff that I can list later on when I have access to my computer

I have the same settings on mine (I also never use GPS so is set to OFF), I have more or less fixed Android OS drain WHILE in stadby (0,7%/h in airplane mode) but when I turn screen on battery goes down quick..we wait your answer if you can give us other tips!

hmm, Well for screen on time Underclocking should help the most. If you don't do any heavy gaming you can set it down to 1.8 without noticing a performance hit ( you could probably take it down to 1.5ghz but I haven't tested that thoroughly so there could be an impact). I use noop as the I/O scheduler but that probably doesn't make a difference. I don't use greenify but I do use servicely. I also stay far away from facebook and the messenger app as that has always caused me crazy battery drain but I know those are apps alot of people would rather not delete so its up to you. I use balance mode in power saver and also use Asus' built in auto start manager to disable most things at boot I don't need. Another thing that helps with wakelocks is to make sure you open the google settings app after you boot ( you dont have to do anything, just open and close. I don't get it either) it works for many people including myself.
Other then that I can't think of much else I do. If anything else comes to me ill be sure to let you guys know

Sudden Major battery drain on Note 4!

I took my note 4 off the charger this morning and used it for about 1.5 hours (no videos, just tapatalk and Web browsing) , and the battery went down to 73%. During this time I also noticed that my wifi toggle was turning off and on for no reason. I don't have smart network control check on.
Then I went about my day and set my phone down, asleep, and didn't touch it. At 11am I hear the "low battery" beep. I go over to my phone and it's at 5%!
My battery has never been this bad before, and this just started today with no app changes. As I'm typing this, my phone went from 20% to 16%.
Is anyone else experiencing this issue (both wifi toggling and battery issue) and know a fix? I've attached my battery graph from today.
Edit: It looks like the phone was "awake" all day today except for the time it turned off due to low battery. Also, it looks like Bluetooth is using way more battery than it should be.
Thanks!

So I found the culprit for the wifi. I have a tasker profile that turns it off when I'm not connected via Bluetooth to my house phone. This means that there is something wrong with my Bluetooth. Nothing has changed with my house phones. Any ideas on the Bluetooth?

Try getting rid of the Tasker profile. I don't think it's your phone. I bought Tasker and tried to set up some cool stuff but it kept messing things up. I don't use it any more. Android does a pretty good job of taking care of stuff without it.

Thanks that was actually the first thing I did when I found out it was a tasker problem. I don't keep wifi on all the time due to battery drain (unless I'm mistaken on that?) so I'll have to bring it back eventually. I didn't think android had a "turn wifi toggle on when home" ability.
I unpaired my house phones and I'm going to repair them tonight and see if that helps.

I've had this happen to me twice including just now hence why I searched for posts on this. Seems like it happens randomly when I stop using WiFi hotspot and I'm at home with my WiFi automatically trying to turn on. I use wifimatic which turns WiFi on when I'm near a cell tower near my home and shuts off when out of range of that tower. My WiFi won't automatically connect if I turn off my Hotspot, so I have to restart. Just twice now this drained my battery from like 30 to 0 in less than a minute. It's not often it happens and I'm home anyhow so putting it on the charger isn't a problem. Maybe this helps but maybe not.

It's been my experience that leaving wifi on doesn't drain the battery very much. I leave mine on. Besides, the quick toggle is very easy to use. Trying to automate it is more trouble.

Wifi is till on while in flight mode - leading to slow battery drain

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.

Battery Drain from "Kernel (Android OS)" and "Android System"

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 :

Unfortunately clicking on either of them only show a long list of processes/packages with no further detail.
I'm running S233 Deodexed, rooted and I've already optimized everything I could with Greenify and that seems to have worked ok looking at the Gsam stats.
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..

"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. "

Any solution got that same huge ideal battery drain. :crying:

Chiming in here with the same problem, never used Google Backup so that's definitely not causing the issue on my device
