From my experiences wifi keeps my phone awake and data transfers like crazy. I set wifi to never stay on when my phone sleeps but this hardly ever works. Most times it stays on!
What's up with this? It works sometimes but what do I have to do to make it shut wifi off when I turn the screen off?

Install DataEasyPro if nothing else works.
AFAIK WiFi only turns off if the connection has been idle for a certain amount of time. If your phone keeps transferring data, WiFi won't shut off. Check your running programs and your sync settings for anything, that could be using your network connection.
The stock ELKC WiFi policy works fine. CM and ROMs based on it do not

As the title said, my Verizon Fascinate scans WiFi every 2-3 seconds and a MAJOR drain in my battery. I believe it started when I flashed EH03 radio, but not really sure if that's the main issue. I have TSM Resurrection 2.1 ROM installed. My kernel is right now geewiz-2.5-kernel (updated on 1/22/12) but I also used KGB-EH03-FA16 Kernel with the same problem. What could be causing this and what can I do to fix it?
Please help!!!
You can set your wifi scan interval in the build.prop, I know there are other ways to do it too. A quick googling should yield a more helpful answer regarding all the ways it can be done.
I thought it only scanned when it's turned on and not already connected to a network though, are you turning it off when you're not using it? I guess I can't really see how else it would be draining your battery.
Turn off WIFI when not needed

Thanks! I will look up the build.prop solution to wifi scan issue. The problem is that it scans continuously regardless of whether it's connected to any network or not. And yes, I have to keep it turned off when I'm not using it.
*update* I checked the build.prop setting and it was set for 120. I'm assuming this is in seconds so shouldn't the wifi should only scan every 2 minutes??? I changed the setting to 600s=10min, but it still scans continuously What's going on???
You're correct, the interval you see in the build.prop is in seconds. If that isn't helping then I'm not really sure.. How can you tell it's continuously scanning? Is it an app you're using that shows this?

The little wifi icon in the status bar keeps going on and off. And when I tried to used the market app, it constantly said I needed a wifi connection.
Anyways, after some additional investigation, I tried turning off and resetting my wireless router - and it worked!!! I'm not sure if that was the only reason for continuous wifi scan, but at least it's not scanning every 2-3 secs now. Well, it hasn't for the last 24 hours, so hopefully it will stay that way
Glad it's sorted! I couldn't really tell from your posts exactly what was happening, but if it's doing that when you have wifi on and (hopefully) connected, then it sounds like more an issue with your wifi connection itself as opposed to just the phone's.
About the wifi scan interval in the build.prop, I believe that just refers to how often it will look for a connection when wifi is on, but not connected to a network.

yes that is correct. I also agree with the issue being related to the wifi and not the phone. i hardly use the wifi on my phone but when i do, i never have that problem. i got grandfathered into the unlimited data from verizon, so wifi for me is pretty much useless.
I've been try to extend the life of my battery, and one of the things I have done is set the SETTINGS/WIFI/ADVANCED "keep WIFI on during sleep" to "never".
I make this change, but most times when I go back into the settings later on, it's changed back to "Always"
Anybody offer a clue as to why this might be happening?
Thanks.

no idea mate it shouldn't do as i have mine set to never and it stays like that, have you been flashing ROM's or anything like that maybe that could explain it!
No, not really.
The only thing I've done is rooted it. Apart from that, It's still got stock Samsung Rom on it.
Just checked again, and even tried setting it to "only when plugged in, but after 15 mins or so, it's back to "always" again.

For anyone else who might come across the same issue.
After doing a factory reset, and putting apps back on one at a time, I found out it was DoubleTwist Airsync, that was changing the "WIFI sleep" option.
Apparently, the developer knows this, but wants it to work that way.
So it's now gone for me
But you won't lose too much battery on an 7 hr sleep with the always on setting.
I go to sleep with my S3 on 98% and wake up with 92-94% battery left even with received messages from 3 email accounts and other notifications.

I keep mine on always. I lose 3% during an 8hr sleep and it'll automatically connect to my carrier data when my network is not in range. Sure beats turning it off and on a handful times a day.
Weird is that WiFi is active in either option you shoose during sleep. Even if you choose NEVER, open your battery use stats and you'll see that WiFi was active all the time during sleep. I cannot understand why is this issue so underrated here on XDA forums. Or is it some kind of misinterpreting from my side???

Yup afaik, choosing never will produce a wakelock to check the phone state and keeping it on will cause it to constantly scan even if connected to a network. Both choices will eat up battery.
I see many threads suggesting to just manually turn it off, preventing scanning, wakelocks and syncing all together.

So it is normal that if i choose Never in wifi sleep policy phone, i find the wifi always on in battery stats? This question is not so clear...
Is there any explanation of wifi toggles by author... Google?

I'm not so sure if you will see wifi in the battery stats as I think wifi processes are part of the Android system in settings >battery.

I use the app keep Wifi alive. It pings my server to ensure I don't lose a connection. I the only thing I see missing with it is that my email sync stops until I go to mobile data.

My Question is when I'm at work my reception is terrible So I use tasker to turn off wifi, data and location access but my battery still drains fast. Is it possible that apps are searching for away to find data access constantly and that's why I'm still experiencing power drain

Could be download greenify and add all your data using apps and see if it helps

If you normally have no bars in that area, your phone may be constantly searching for a signal. You might want to consider switching to airplane mode to stop that... Just be aware that you won't have call/text while in this mode. This will also keep mobile data off although WiFi can be turned on and used in airplane mode.
Another thing you can try is get the 'betterbatterystats' app from these forums and check for unwanted 'wakelocks' after it's been installed for a few hours or more.
Sidenote: Having location (gps) ticked on all the time shouldn't drain your battery, but turning off the internet (mobile data/Wifi) when not using it is a good idea as you've been doing.

My cellular Internet randomly stops responding in the browser throughout the day even it says I'm connected to LTE. I have to turn airplane mode on/off to get it working again. Just wondering if anyone else has experienced this or is it just me.

Me too, it will sometimes say, "Phone is not registered." I came over to T-Mo to save some dollars, so I was unable to determine if the issue is T-Mo's network or the S5. Especially true since I've always had HTC phones. My issue does only seem to happen in stores and where I work, so I assumed it to be T-Mo...
I also have a problem with the Wifi not remembering my password. Strangely this only seems to happen when I check the "Smart Network Switch", which is SUPPOSED to make it smoother...
It happens once in a while. Toggling Airplane Mode on and off fixes it.
Happens to me too. I don't think it's the phone, as I was having the same issue with the S4. Had to toggle airplane mode.
Sent from my SM-G900T using xda app-developers app
Same here, it happened very very occasionally with the S4, but it seems like it's at least once a day if not more with the S5. I had a separate microphone issue on my first phone so this is my second device that's had this problem. The airplane mode toggle works, and also turning wifi on and off works for me. The problem is when I don't realize it's happened and I miss a call which is problematic for obvious reasons. I've missed several calls in the last few days which I find unacceptable, if this doesn't get sorted out I'm going to have to switch to another phone soon...

same happened to me had to return the phone through buyers remorse program seems it's an hardware issue a simple restart or reset of Internet via airplane mode will fix it but annoying
I'm also having the issue. Not a major issue as it doesn't happen too often.
I notice I get it when I am connected to wifi. Doesn't seem to happen as often when wifi toggled off.
Same here I had the s4 it just recently like a month ago I though it was my s4 but when I got the s5 same thing so its nost likely a t mobile

Anyone else have an issue switching from Wi-Fi to mobile data? When I leave the house and turn off Wi-Fi, the mobile data will light up the indicator and have a good signal, but actual internet use acts like there's no connection. I have to disable mobile data, then enable it again to get anything to work.
This is using the Verizon version, and I also recall this happening on my V20. I had hoped this would've been resolved at some point.
I am having the opposite issue. When I don't have WiFi on and try to turn it on, the blue indicator lights up and then abruptly turns off.
The only way I have found to get around this is to tap on Wi-Fi and while it's lit, restart the phone all together. Then when it powers up, it will connect.
I'm having this problem I have to restart the phone for the internet to work again. I'm on the T-Mobile version

I was restarting as well, but found simply turning mobile data off and on would get it working again. Not a fix, but saves a little time.
