This is for stock (rooted) Lollipop on g800F.
I turned-off WiFi.
I disabled High Accuracy location (set it on GPS only).
I disabled "Allow scanning" and "Network notofication" in advanced WiFi settings.
And yet, on Battery usage chart, the WiFi bar shows that it is on ALL THE TIME. What gives? Is this a bug in Touchwiz?
Did you disable Bluetooth as well? The same happens in airplane mode? My bet is the Wi-Fi/BT chip is the same, so you cannot completely disable just Wi-Fi...
Also, some app may have access to Wi-Fi and keep it one. Some anti theft apps like Avast are known to cause this...

How to prevent wifi from sleeping?
I have a few apps that have the permission of "prevent phone from sleeping" but seems the phone will still switch off the wifi soon after the screen timed out. Is it supposed to work like this, or is there some settings for this?
one of the apps i tried is "wireless file transfer lite", which by the way, is a very light wifi transfer tool between phone and pc
Wifi settings > menu button, advanced > Wifi sleep policy.
ha! didn't know there is advanced setting.
many thanks!
I hope this hasn't been covered, a search (here and on Google) did not really help.
On my XT860 I seem to have an open internet connection constantly. When WiFi is turned off, HSDPA (or EDGE) is show as active constantly.
I think this was not the case in the beginning but I am not really sure about that as restoring a (very early) backup does not solve the problem.
I killed every single App about a hundred times but without any changes in this behaviour.
Turning data save mode on is of no use either. Statistics show very little activity (Upload/download) anyway, so that's not it. It's just that it stays connected all the time without doing anything (other than draining the battery).
Does anyone have any idea what could be causing this? Or which steps I could take to narrow the problem down? Or is it even 'normal' (albeit annoying) behaviour?
I would be grateful for any input as I am running out of ideas what to try.
SETTINGS>BATTERY&DATA MANAGER>DATA DELIVERY, and disable "Data enabled" and "Background data"
for a better battery life, disable also UMTS/3G networks, only 2G remaining active.

Thanks but disabling background data does not seem to change much. The H+ symbol is still there all the time.
I do not want to disable data altogether as this basically render many functions useless.
Or is this just normal? Is the symbol there all the time when data is enabled and WiFi is off?
Considering that they don't bother to explain the status icons in the manual I wouldn't know...
Hello everyone.
I just wanted to get your attention on a major Android OS (Kitkat) bug in the interaction between Wifi -> Advanced -> Wifi Always Scan and the Location Service. Clearly the bug doesn't happen every time, but sometimes it does, and obviously I'm talking about stock rom / kernel / no root / locked bootloader.
Althought I can't prove it, this might also be the cause of the current GPS / Navigation issues, currently being reported here.
What makes me link this to that issue? Because when Wifi Always Scan bugs out, it prevents my phone to acquire a location even from the 3g network.
That would explain why in that thread many people report that they could navigate with Device Only, which doesn't use 3g or wifi for location, but they had major issues with High Accuracy, which uses all three sources.
Please take a minute to star the issue so that Google will hopefully fix it faster.

Thanks for your useful contribution.
It doesn't waste battery, it saves it. It enables to use the wifi location using a lower power state of the wifi chip compared to actually turned on wifi (which is also more accurate by miles than 3g location, works indoors in clubs where there is no 3g or gps signal, and not as battery expensive as gps location).
Also, people use that option for many things, I for one use it in MANY Tasker tasks flawlessly, whether the alternative (wifi periodic toggle and polling) would rape my battery.
Wifi automatically Turned off. Built in feature?
I kept my wifi on, and the had not used it basically just left the device in the room and had run off.
When I retured, the wifi was on in the power control widget but the wifi signal indicator icon in the notifications bar was absent.
is this normal/intended?
My wifi / internet connection is weak but continuous and my device is about ten to twelve feet away from the modem / router.
Can anybody help?
Although I have not a Nexus 5, my problem seems to be the same. I'll tell you if perhaps serve as any indication.
In my HTC EVO 3D, I've been running since the summer with CM10.2 (Android v4.3.1) with location mode set to "Network & WiFi" and "WiFi Always Scan ON". During this time the location was very accurate, location history left a fairly detailed trace. In Google Maps, was located immediately, as in Google+. If activated the GPS, even better. Summarizing, 0 issues with the location.
On January 1, I decided to upgrade to CM11 (Android v4.4.2), I set my location mode to "Battery Saving" & "Wifi Scan Always ON". During the first 10 days everything was perfect, the location history trail was so detailed as CM10.2 and battery consumption a little better. Google Maps and Google+ also positioned themselves almost immediately. Suddenly, on January 11 the location seems to stop of using WiFi networks and began guided only by the Network Cells (being rather more vague). Also when for some reason failed to position (being out of range of Network Cell), the phone started to not enter Deep Sleep Mode and the battery started to discharge at high speed. Google Maps, Google+, 1Weather ... were unable to obtain the current location or showed the last known location of hours before. Rebooting the phone sometimes temporarily solved the problem, but sometimes not.
I tried to change the placement options; abroad, with "high accuracy" mode, the location worked well, but indoors the GPS was not able to find satellites (logical) and still the same problems. I enabled and I disabled the location, nothing. Factory reset, no change.
To rule out a hardware failure, I returned CM10.2. Everything about the location worked smoothly... Return to CM11, again the same problems.
In short, my impression is that this is a software bug, as in versions prior to v4.4 Android location "Network & WiFi" + "Scan Always ON WiFi" works correctly. Moreover, not only occurs in the Nexus 5.
I have marked with a star your ticket.
I'll keept testing.
I get this problem when I use tether with WiFi always scan enabled.
When I disabled tethering, I have to manually enable WiFi to fix the location reporting issue.
With WiFi scanning not enabled, I do not get this problem

I think I have similar problem and I really hope smbody can help me.
On my stock nexus 5(4.4.2) wifi location don't work in google maps and ingress, when I turn it on instead of gps location.
But in other apps wifi location works( yandex.maps, 4square)
Only reboot helps
Hello again.
I just updated Google Maps to version 7.6.0 and Google Play Services to version 4.2.39 and all the problems I had with the location are gone, everything is okay again, as it did in CM10.2. So it looks like it is confirmed that it was a software bug.
Sorry, I know this post is quite stale, but I came across it doing a search about this very same problem I've seen on my LG G4 (stock). I have a Tasker task that uses WiFi near state and I use the "Allow Wifi scanning..." option in my Advanced WiFi settings. Whenever I would use WiFi tethering and then later turn it off, I noticed my Tasker task would not detect the WiFi networks it was supposed to. If I turn the "Allow scanning" option of and back on, or just turn on WiFi altogether, it starts working again.
So, after more than a year and a half, and on a newer version of Android and it still doesn't work right. Who knows; maybe it's a Tasker problem.

Hi guys,
Just a quick question.
Under Location, I notice that there are three options for Location Mode:
- Device Only
- Battery Saving Mode: which uses Wi-Fi.
- High Accuracy Mode: which uses Wi-Fi and GPS.
Excluding High Accuracy mode, which mode uses more battery: Device Only or Battery Saving mode?
Thanks,
device only = gps only. so that would use more than wifi. honestly i would just keep it high accuracy, but turn on/off location when you're not using it.
I havet just GPS on always and thats no need to turn location on off . As long you dont use any app that demand location the GPS is off and doesnt use any battery.

Use device only. Here's why :
Google Services such as Gmail, Now, Maps, and Google+ constantly polls your location using your wifi (if you're connected) or your cell network. And every time Google Services poll your location, your battery gets affected. So what's the solution to that?
Solution
Further research by Galaxo60 proved that going to Settings - Location Settings (or Location on android 4.4), and unticking WiFi & mobile network location (or setting the Mode to Device Only) prevents Google Services from polling your location, thus preventing the battery drain
So disable the WiFi & mobile network location option, and actually tick and turn on GPS satellites. (It's just like setting the Mode to Device only on KitKat)
But why do that? Why should by I turn on GPS?
Explanation
Google Services don't use your GPS to poll your location, so your GPS actually stays offline most of the time; and the reason you should enable GPS is to "Let apps that have asked your permission use your location information".

Hi everyone
I have a profile that that kicks in every 30 mins from 8 am to 9pm, to sync my account. I have set it up to use wifi first, but if there is no wifi connection it will go to my mobile data instead.
Now here is the problem if my phone is on standby it always connects via mobile data regardless of a wifi connection is available. But if I am using my device at the time when the task runs then it will connect to wifi. I have checked my, keep wif on in sleep option and it is set to always.
Could anyone explain as to what this is happening?
Thanks in advance
What is your Android version?
I am currently using a custom rom called exodus which is currently based on marshmallow.
Check if Tasker is excludied from Battery Optimization and whether Wi-Fi is not deactivated while the phone is in sleep mode in Settings/Wi-Fi/Advanced/Keep Wi-Fi on during sleep.
yep tasker is excluded from battery optimisation and the allow wifi during sleep policy is always.
If you're turning wifi on with tasker action wifi turn on, try instead of that shell script "svc wifi enable".
Ok thanks, I will let you know the out come of this. I was using secure settings to enable Wifi as the command built in tasker, is not compatible from kitkat and onwards if I remember correctly.
I found out "svc wifi enable" command does exactly the same thing
Discovered I'm having the very same problem on cm13 and the batch jobs have been done by initialized mobile data. Finally found out a solution to initialize wifi instead of mobile data. I've no limited data plan, but wifi is more battery friendly.

Do you actually wait for wifi to connect?
Does your phone do the low power screen off wifi thingy?

Yes under normal circumstances it takes about 20 seconds to connect.
No because for some reason my wifi will only switch on if the screen is on.
I also have uninstaled my custom kernel, but this issue still appears from time to time.
There's a setting in wifi connection settings that you can set to that says "keep Wi-Fi on during sleep"
This same setting is often repeated in battery apps like powernap, naptime, better battery saver etc.
Even though the wording is the same, I don't believe they are all touching the same setting so go find those apps if you have them installed.
Also, disable all native battery savers (including Samsung 2 or 3 different ones,, doze, battery optimization etc etc just to see if your problem goes away.... Which it will. At least you'll know though
I have the same problem with Wi-Fi connection.
I have a profile to turn Wi-Fi on and try to connect when certain conditions meet and the screen is off in that case.
It seems that the phone has difficulties turning Wi-Fi on and connecting to it when screen is off. Tasker does manage to turn Wi-Fi on but the phone somehow does not connect *reliably* in all cases.
Tasker is excluded from battery optimization, Wi-Fi on during sleep. I tried turning cpu on for a short time hoping that it will connect, but still no result.
The only possible solution might be turning the screen on briefly at that moment.
If anybody has a better idea, you are more than welcome to share!

I can certainly say that turning the screen on will enable wifi, as I have resulted to this as well. But unfortunately I do not know any other solutions to try.

My Wifi is set to always "keep wifi on during sleep"
I'm going to resort to flashing stock rom again and see if that helps. As I am only using doze and amplify to save battery, all settings for that has been adjusted to the guide I found.

Before reflash, just disable xposed and see what you get... I will bet half of this soft taco I'm eating your problem disappears with greenify and or amplify. I'm not saying don't use them at all... Just make sure it works without them. I used to have some serious battery apps, but found after disabling, my battery was IMMENSELY better. And I had no config to deal with. But first things first... IT'S without a doubt, no question, a battery app setting or a system app that's being put to sleep that should be white listed
