Turning wifi off when screen is off

Is there a tool or app that will turn wifi (and perhaps data) off when the phone display is not on?
My wifi is using a lot of battery.
Thanks.

When I read this, my first thought was this function in the Android Wifi settings. Not entirely sure if this will solve your problem, but give it a try and see if it helps.
From Google's Support site for Android, under "Advanced Wifi Settings" (It's for Android One, but still applies):
Keep Wi-Fi on during sleep: Touch to choose how your device handles Wi-Fi when it's asleep. You can choose to keep Wi-Fi on all the time, only if your device is charging, or turn it off completely. If you turn Wi-Fi off, you may increase the amount of mobile data you use.

You are correct. It is in android settings under advanced in wifi.
Thanks.

LeanDroid
I liked LeanDroid. I used to get battery for more than 24 hours.
But with Lollipop, it needs root access.
Rooting is not easy with Lollipop
Hence, I am also stuck like you
Waiting for 5.01 version hoping to get some fixes.
Drain with my phone is not just WiFi Mobile network too and generally the green bar slopes down.
Kitkat and LeanDroid were good
You can still try LeanDroid

Thanks. That helped me too.

wifi off, when screen is off
after updating to lollipop (stock), i am unable to connect to my college wifi. but i could use my wifi at home. now after few days my wifi is going off, when the screen goes to sleep. what kind of a problem is this ? when can the nexus 5 users get 5.0.1 update ?

[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.

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.

You're not alone I'm using mine, but WiFi wasn't on top of the list ever in 5.1.1. Has to be a bug

Ive got this issue as well. Its really annoying. I always keep Wifi off to extend battery life but with M I might as well just keep it on...

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.

During initial setup Google asked me if I wanted to keep WiFi scanning enabled to help apps with location to find the location easily.. I declined.. Hence they were off..
Did it help with the battery?

Just an update on battery life. 1.5h SOT no WiFi bug (after sideloading the OTA update) also noticed the battery graph added Camera and Flashlight if they were used

Also discussing the same issue here:
http://forum.xda-developers.com/google-nexus-5/help/wifi-plaguing-android-marshmallow-t3220031
Try to set it 2.4 Ghz only instead of auto (2.4 +5)

WiFi plaguing Android Marshmallow

After using 6.0 for a day or so, I noticed that the WiFi was draining huge amount of juice from the phone, even taking the top spot on the battery chart. This seems to happen even if the WiFi is turned off.
http://i.imgur.com/X2YoNvv.png
So how can we fix this? Well, we'll have to go through bunch of settings to do so. It seems like Google deliberately hid this deep inside location settings. This is how we can "temporarily" fix this issue: Head to Settings -> Location -> Click those 3 dots at the top right corner -> Scanning -> Turn off both WiFi scanning and Bluetooth scanning.
Even with this "fix" I noticed that it keeps draining battery life for no reason, not as much, but the problem still exists. This shouldn't happen! Especially when Marshmallow was built around battery life improvements. The fact that this bug has been causing problems since M Preview #3 shows either Google "missed" this chaos of a bug (or) only cares about that juicy location data. This should be a straightforward-user-friendly option, not one that is buried behind buttons and menus.
It's not a bug, it's a feature

Had the same issue after flashing the factory image. So I flashed 5.1.1 again booted the phone then rebooted into recovery and sideloaded the 6.0 OTA. Booted the phone and preformed a factory reset. Now I don't have that problem.

im currently having this exact issue.

I had same problem also tried disabling Wi-Fi scanning and automatically turning off Wi-Fi when idle but it did not give better results.
Just today i switched phone Wi-Fi to 2.4 GHZ only mode - this workaround seem to work, no drain any more.

Thanks for that. This actually sounds possible.
On the first day when I flashed 6.0 with OTA, I really felt that the battery life has extended.
Then I switched through a lot of settings and also ended up with 2.4 and 5 (auto) on wifi.
Disabling all wifi related options did not help at all....
Will try this out now. :good:

I'm having severe delays with my wifi on my N5 with 6.0. In speedtest I'm pushing over 90mbps on 5GHz band, but it takes over 30 seconds to load a webpage/ apps. It's not gradually loading it's almost like a stall. Then after the page or app loads instantly. Why is this happening? Is it a severe delay to the server? IDK wtf is going on... I don't have battery drain issues from the wifi this is a different issue.

Same problem... Scanning and wifi off! Wifi drain. At first sight problem only seems to manifest while no wifi available. Tried the 2.4ghz only and seems to reduce though not eliminate the problem...

Works indeed better.. Wifi disappears from the Battery Usage chart, but when it was supposed to went on idle while I put it away, draining started again it seems.
There is a fat bug in the Power-Management in Android M 6.0 final, if you ask me...

All, please check whether it is actually drain or merely incorrect reporting of battery statistics. Symptoms seem similar to this thread
Remember battery 'drain' is where the level is falling at an abnormally fast rate. If WiFi is merely appearing at the top of the stats, but your battery life is actually fine, then it's not drain.
You need to leave your phone over several hours, and take measurements. When investigating or troubleshooting, then logically change one thing at a time, and re-measure again over a long period of time for comparison.

There is definitely a drain problem... because of Google Play Services not letting System into sleep mode and pulling constantly on Wifi...
That is how I think it comes to the problem.
Mine is now running smoothly, after I went into: Settings > Apps > Google Play Services (and maybe also Google Play Store) > hit menu ... > Deinstall Updates > Restart
If you go back into Play Store later on, it updates to the current version.
I also reseted the Network Settings... somewhere.

I tried what was suggested by others in this thread and din't have any luck. I posted how I solved the issue here:
reddit dot com/r/Nexus5/comments/3npesh/wifi_drain_persists_in_android_m_final_release/cvwo3x5

I did another modification. In Location settings I changed mode to device only (GPS).
So together:
- set WIFI to 2GHz only
- disable wifi scanning in location settings
- set location scanning to device only (GPS)
- set WIFI to automatically turn off in idle mode (advanced wifi settings)
WIFI is no longer main battery consumer (screen is now as expected). I'm not sure which of those is crucial but they all look like may improve things a bit (and together give big difference)

.

I thought this was bugging me too. WiFi is top of the list in battery stats. But then I disabled ElementalX gestures (doubletap2wake in my case) and that improved things a lot. Even though WiFi is still reported as the biggest power user.
This may be just me and of course it could always be better, but it might be worth giving this a try.

I'm having his exact issue. It's with any resources I access through WiFi, from sftp to ftp to web data, internal and external lans, internet, etc. It's definitely a 6.0 issue. I had it on preview 3 as well, and it was bad enough make me downgrade at the time. Now the official release is out and doing the same thing, I'm REALLY hoping they can fix this soon. It's practically unusable if you don't have dial-up time to kill.

Check my previous post - it completely fixed problem for me

I've experienced the same issue, after a week from the ota update (week in which I had a great battery lifetime), the problem arose out of the nowhere, and after searching the web for a workaround, it seems that putting the wifi in 2.4 ghz only made the trick...
Really hope that google will fix this soon...

This is the only thing that worked fully for me. Getting it to 2GHz made it a little bit better but didn't actually solve it. Uninstalling updates from play services and play store solved it for good and I didn't have to flash 5.1.1 and ota update.
:good:Thanks eyesore!

Hello. I have this issue... I disabled localisation through WiFi and I have also done a network settings reset but the problem still persists (not too much as before -45%- but around 25%).
How can I solve?

[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.

Boot to recovery and clear caches, reboot and see how it is then

done. Sadly, it didn't help me.
edit: I've just used this app but it also failed. If nothing help me I will wait till Monday to show it to my coleagues from Customer Support. Maybe they will find solution

I'd backup with smart switch, and factory reset the phone
Or flash the latest stock ROM over the top with ODIN

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
Video on Dropbox
disabling "Wi-Fi scanning" in location helps.

Hi,
I had the same issue before.
What I did was(Not sure how its displayed in english):
-Settings;
-Backup and Reset
-Reset network settings
I was having constant disconnections from wifi and it solved it.
Give it a try

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.
