[Q] Nexus 5 - Battery usage shows Wi-Fi always on?? (even when manually turned off)

I'm on a 32gb Google Play purchased white Nexus 5, activated on Sprint. I went through a whole charge cycle yesterday with Wi-Fi off, and under battery usage / Wi-Fi / Use Details / Wi-Fi running, it showed "Wi-Fi running" 17 hours. I never even had Wi-Fi turned on once.
I've been playing with it today, turning Wi-Fi on and off, and no matter what, the Wi-Fi usage time matches my phone on time. It seems according to the battery meter my Wi-Fi is always on. Any one else seeing this? What is the deal?

Go into wifi settings, click the menu button in the lower right corner, go to advanced.
Uncheck "Scanning always available". There you go.
Although TBQH the battery impact seems minimal (especially if it's able to use wifi to get a location lock, as that's much more power efficient than turning on the GPS).

that is because even though you have turned WiFi off, its still available to app to get better location. if you want to turn that off, go to settings, wifi, options, advanced and uncheck "scanning always available"
that will turn off wifi completely. hope that helps.

Go into WIFI settings and click the menu (three dots menu) for advanced settings. You will find an option that makes the phone to scan for networks even when disabled.

Thank you all very much! Will see if it helps my battery life at all!

Thanks folks.
Following my update to 4.4.2 I was experiencing wifi using a lot more battery than normal. I tend to turn wifi off at night, and phone had started using more battery than normal. This fix in advanced settings got things back to normal for me. Battery usage much better. Odd that the update seemed to have set this to on for me.

Thanks a lot guys..this was bugging my head as well..

Hi Guys,
I've just updated to Lollipop by sideloading the OTA.
My battery usage stats say that my WiFi is constantly on and the phone is Awake, even with WiFi turned off AND 'Scanning Always Available' also turned OFF.
What could be going on and does anyone have any suggestions to fix?
Thanks

Same thing happening to me Wifi constantly on Android 5.0 Nexus 5

Same thing is happening to my device. I upgraded to Android 5.0 yesterday using the OTA upgrade and battery life has been horrendous. When I view battery use it shows WiFI as being constantly on...even when I have it manually turned off. I also have "scanning alwaysa available" turned off. Need more insight on this issue.

I had this same issue. I think I fixed it, check out my thread for a solution: http://forum.xda-developers.com/google-nexus-5/help/fix-lollipop-wifi-off-t2947870
Basically, flash Kitkat factory images, sideload OTA, factory reset, and hopefully that resolves it. Nasty little bug.

Thanks
Thanks for reading my post and suggesting the solution you have written up on your thread. I am going to see if somehow the problem becomes resolved within the next couple of days. Otherwise, I will flash back to clean KitKat image and upgrade to Lollipop as you suggested.
When I upgraded to Lollipop yesterday, it wasn't a clean install. I simply installed over my current KitKat config.

Thanks for the reply, but what you suggest is basically how I have arrived at this situation...
1. I flashed the KitKat factory images a few months ago to resolve an unrelated issue
2. I sideloaded the Lollipop OTA update earlier this week, then discovered the WiFi Awake issue chewing battery.
3. I performed a factory reset (from the O/S, not from recovery) 2 days ago and then re-setup my phone, making sure to untick the option during setup which turns scanning always available on.
4. Today, with Wifi turned off and scanning always available turned off, my phone battery stats indicate my WiFi to be constantly ON.
That said I will give your method another try, but beyond that I was considering flashing the Lollipop factory images, will this help?
Cheers

How I arrived at that situation was by clean flashing the Lollipop factory images Maybe try it again? I'm honestly not sure what the difference in doing the two is (flashing factory Lollipop vs flashing factory Kitkat -> OTA -> wipe), but it seems to have done something for me. Also are you rooted? I did not root after following those steps, as all I really used root for was monitoring battery stats.

I had the same issue as well and found it was actually caused by viber app. if you have viber app you can got into the app
->settings->general->Wifi-sleep policy and change it to use device's settings.
If that doesn't help try booting into safe mode and check your battery stats, thats how i found out it was actually caused by a 3rd party app.

A question?
My wifi is always on too as a function of Settings>Wifi>Advanced>Keep Wifi on during sleep>Always.
My question is, when I'm at work I have no chance of connecting to any Wifi networks (there aren't any!), is it going to save my battery turning this off?
Regards all,
Paul.

I have a 32 gb nexus 5. My Wifi is always on. Whenever i try to turn it off, it automatically turns right back on. If i restart the phone, wifi will be off for sometime. But as soon as i go to the drop down menu, zap, its on again. Any help on this? And of course this is draining my battery faster.

============================================
1. Wiping Cache Partition.
2. An app must be interfering with the android system. Uninstall applications like Clean Master, Ram Boosters, Process Killers ,etc.
Your phone doesn't need these optimizers and they are the source of the problem creating problems with the usage, asking for permissions to interfere with the system.
NOTE : Process killers, ram boosters mostly the problem, you don't need to disable WiFi everytime after use, just go to wifi options -> advanced -> Keep wifi on during sleep -> Never and select WiFi freq band as requied.
After this step you need to clear cache again and then you will never see WiFi on top i.e System will function normally.

[Q] [Help] Wifi drains battery even though turned off (Lollipop)

Hi everyone,
I am new here, and would like some help with my Nexus 5.
It is running stock rom and everything, Android 5.0.1 LRX22C
I am still setting up, so still using my old phone while I get all the mandatory apps on before i switch my SIM over.
I realised that battery seems to be draining rather quickly even it spends most of its time on just Wifi right beside the router. Cellular connection is not on. So one day I decided to turn it to airplane mode and see what happens.
As you can see from the attachment, WiFi was on all the time even though the phone was on airplane mode. I believe this is the cause of the battery drain. I did not turn WiFi on.
"Scanning always available" was turned off, and the top battery drainer is "Android system", but at only 1%.
(The screenshot was only taken after I reconnected Wifi and downloaded GSam, that explains the notifications.)
Does anyone know the cause of this? I'd prefer if I do not need to factory reset the phone as I am pretty much done setting up everything and I don't want to have to do it all again.
Any help would be really appreciated.
Thanks!

If you go to 'Advanced' there should be an option called 'Keep WIFI on during sleep', click there and then click 'Never' or 'Only when plugged in'. Good luck.

I too had the same problem when i updated to lollipop but after some days of usage i found that in wifi under advance there was a new option scanning always available which was turn on. What this setting do is even if ur wifi is off the app can scan for wifi signals for the location. So if u want to keep ur wifi off just turn off that setting.

I already had it turned off, but the battery settings still reports WiFi as on. Weird thing is GSam says my WiFi is off, so I'm not sure what is the problem now.
It might be the Android System, reporting it uses even more battery than my screen now.

[Q] Wifi issue ! (Lollipop 5.1)

Hi All,
I got the Lollipop 5.1 OTA 2 days ago and installed it - everything went smooth and the phone working fine...
But I noticed that if I reboot my router (or turn it off / on again) the Wifi don't reconnect unless I turn on the screen (the second I turn on the screen the wifi connect normally).
I didn't have this issue with Lollipop 5.0.1
P.S.
I know that this is happening because I have a led on my router telling me if any of my Wifi devices is connected or not. And to make sure I also entered the router settings to see if my phone is connected or not.
Anyone noticed that issue with the new lollipop 5.1 ?
Cheers,

I think that your problem is not switching off the router. The problem is when your phone goes to suspension (screen off) and then it drops the wifi off.
My Nexus 5 with 5.1 is doing the same

I've got some similar behaviour here, both when updated from 5.0, and with a fresh install from the factory images. When I arrive at a place with known WiFi, the phone only connects once I turned on the screen. After that, it stays connected until I move out of range and back again.

It's probably a matter of responsiveness/battery life. The more it polls for networks, the more battery it uses. It should connect, even with the screen off, within a few minutes.
That being said, I have my wifi set to always stay connected, and I've seen it not connected when I turned the screen on, then connect a couple seconds later. So, there's that. Curious how often it does that.

That's what I suspected. Sometimes, the waiting game works, but I've had my N5 lying on my desk – where it usually gets full WiFi bars – for about 40 minutes the other day, still it did not connect until I turned the screen on.
Edit: Just now, my phone disconnected from WiFi when the screen turned off, which leads me to believe that this is all caused by the WiFi sleep policy. Could it be that Google messed up something there?

My "research" has led me to believe this is the case.

Anything in terms of a workaround?
I came across those settings in the developer options (see screenshot), especially the "Always allow WiFi Roam Scans" looked promising. Been playing with them, but so far no luck.

Hi All,
exactly the same issues as yours guys are happening since I received the OTA 5.1 and installed it !
I Guess something messed up with this new update in regard of the wifi... as you mentioned.
If you come across a workaround or a confirmation from "Google" please share.
Cheers,
(With almost everyone nowadays having data ..it is difficult to notice such a behavior due to the fast wifi/data switching)

I have seen this happen as well. My battery graph will even show a missing area for WiFi indicating it turned itself on and off twice within a few hours and then stayed on after that.

Google just now released LMY47I, has anyone had a chance to see if that version fixes our problem? Once I'm off work (in about 8 hours), I'll give it a whirl and report back.

Could you please elaborate on that? I'm familiar with Tasker, but I can't think of a way of dealing with this, since I'm not sure what actually happens with the WiFi. The settings appear untouched.

I'm sorry, but my phone is now in the service center , and press that I do not remember specifically . The idea is that when you disable wifi, a time interval is forced to connect to a particular network . Look presence on the internet , here is full of instructions.

Almost all of the changes on these different builds are SIM related for specific carriers.
LMY47I was only released to LGD821 devices with SIM cards from Indian and Australian carriers

Same problem here. I am slowly losing faith in Google. Get the frickin basics going guys!!!
Back to my 5.0.1 build.

I've gone back to 5.0.1, too. Pity, except for this I was pretty happy with 5.1. Maybe 5.1.1 will actually be usable.

Do you think it can be related to Issue 163350? code.google.com/p/android/issues/detail?id=163350
I have just reported that, but I'm still trying to understand if it just happens to me or what.

I think the solution is "use vibrate mode on". Get your device to vibrate mod and test it.

I have this proble too

WiFi is turned off yet is reported as turned on and using battery.

My wifi has been off since i upgraded to M, clean install from the Google images. It still reports my wifi as on and using up my battery....is this a bug or am i reading this incorrectly?

I don't know if this is a setting in marshmallow, but I know in KitKat if you go into the advanced settings menu on the wifi page there is an option that allows the phone to automatically turn on and scan for networks without any user intervention. That setting should be turned off.

huh...mine is set to Always keep wifi on during sleep. Does that matter even if wifi is off?

Since I'm still running kitkat i can't speak for marshmallow, but on KitKat, the wifi on/off toggle takes priority over that setting. Wifi will only stay on during sleep if it was turned on to begin with, but that isn't the issue you guys are experiencing right? There might be an option in that same menu that says something like "let Android search for networks even if wifi turned off". That gives the results you guys are experiencing.

Go to settings-->location-->menu-->scanning and check if WiFi and Bluetooth scanning options are kept on..
I don't have this issue..

Both are checked, i unchecked them both. What were the status of yours?

When I flashed the Factory Image (6.0) I had this problem. I flashed back to 5.1.1 booted the phone. Then booted into recovery and sideloaded the OTA update to 6.0 booted the phone and preformed a factory reset. I do not have this problem anymore. Wifi doesn't even show up in the battery stats.

[Q] wifi switches on and off

Hi,
since yesterday I have problem with wifi in my S7 (SM-G930F). It keeps turning on and off every second or two. I cannot switch it off because it keeps switching. I have rebooted my device, but it didn't help me. My phone is not rooted, it has stock 6.0.1 firmware. How to fix it? Despite it's impossible to use wifi now, it keeps draining my battery.

I saw it yesterday at work, but not authenticated. Now it is remembered in list. Sadly S7 has no option to forget networks out of range. Todays we have national holidays, but on Monday I will be at work and try to forget this network. I do not want to change rom because rom from my operator has wifi calling enabled and it is awesome.

Is there any chance that WiFi scanning is turned on? I recently saw that WiFi scanning will briefly turn my WiFi on then off repeatedly (shows with an indicator on top and I hadn't noticed that before). This first showed up when I installed Android Auto since it turned on my WiFi scanning option by default. As soon as I turned WiFi scanning off, the WiFi worked as it had before. It may be worth a look.

I've run into the same issue. Started yesterday, which may have come with the latest PJG update... Not sure.
But it's rendered my phone pretty much useless. The constant toast message popping up, saying "Network connectivity is available" gets in the way of the keyboard and I can't type a damn thing!
Like you, I've found it's stuck with reboots and a factory reset, which makes me think it could be the firmware or modem.
Edit: Disabling WiFi Scanning stopped the errors. Root cause is still unknown, though. I've never had to disable that before...

Yep. It was turned on, but I have it enabled since I bought this phone. Turning off neutralized my problem, but why it was broken for last few days when I haven't done anything with my phone? I rely on this feature because of localization accuracy and disabling it is just temporary fix.
edit:
Guys, one more thing:
do you have "Samsung Gear" app installed? I think this app is forcing to enable and disable wifi. Under localization it shows battery usage as high and it was updated last week

My phone does not have the Samsung Gear app installed. I do use Samsung Pay regularly and that was also updated (engine and app). I don't know how that would relate to WiFi though.

Turning off WiFi scanning stops the constant switching of WiFi. I tried removing the system settings permission from all the apps that had it (even the Google app) but it doesn't seem to have any effect.

I am seeing the same issue, I did not touch my screen in the following video

Did the above solve the problem?

I am using G930F in US on ATT and encountered the same problem in past few days, where wifi kept turning on and off. Was searching this post, and found out that if i turn off wifi scanning i can get wifi to stay off (when i switched off ) and wifi on (when switched to on) and not flip back and forth.
go to settings.
- click on search
- type in improve accuracy
- select from choice
- turn off wifi scanning
Try that and hope that helps.

I have the same problem. The side effect is that it will drain the battery really fast.
As others have mentioned, after I have turned off the WiFi scanning in the location setting the problem is temporarily gone. However it should not be the solution as I really need the WiFi location to work. I don't know what is causing the bug.
P. S. I only see this problem starting from the last week or so. I leave the WiFi scanning location function on since I have bought the phone in May. Mine is Exynos version.

several Samsung devices have this issue.
I and several others have it on a note 4, and some people have also reported having this problem on S6 variants.

The problem is Google Play Services 10.0.84 version. Another cell phones with this version of Google Play Services have the same problem (ej. Google Pixel phone) but not all.

The problem is the Android Wear App. Deinstall the app and wifi works perfekt.
This issue starts with the last update of the wear app.
Hope i could help you.

I tried uninstalling Android Wear but it didn't make a difference. The wifi kept switching on and off.

As mentioned above, it's Google Play Services 10.0.84. Just disable wifi scanning until there is an update. Hopefully google won't take too long to push a fix.
