I've noticed that despite setting "Keep Wi-Fi on during sleep" to "only when plugged in" and disabling "scanning always available" Wi-Fi continues to deplete the battery at idle. According to the details in the battery stats, the Wi-Fi never turns off at idle (the Wi-Fi is shown as being on the entire time the phone is unplugged). I've found the only way to stop the Wi-Fi from depleting the battery is to disable it entirely. Has anyone else experienced this? Does this have anything to do with the kernel I'm using? Is it possibly a bug in Franco's kernel? Does this vary with the stock kernel or other custom kernels? It's not a major problem, but I'd just like to know why Wi-Fi is using up juice when it's supposedly turned off. Thanks.

It's a 4.4 deal. Pretty certain it's intentional on Google's part.
The setting worked for me. Whenever the screen was off it would switch to my data connection instead. This turns out to use 3x as much battery while idle then WiFi did in my case.
You could disable background data which wouldn't use WiFi or data but also leave your phone unconnected.

I have battery drain issue when I use wi-fi for few min and then turn it off. After this the battery drains crazy but if I never turned on Wifi battery drain is normal.
Another issue is when Today Touch plugin's weather is updated by Wifi then it won't update with Active Sync connection?
Did anybody see these problems? Anybody has solutions?
I probably cannot help you other than to remind you that the gurus here will need more information so that they can help you. What device do you have, what ROM, what programs you've installed, etc. Also, these issues have been discussed numerous times with various ROMS, so searching will probably yield a great deal of information. Good luck.
My device is on XDAR2a release. Touch stuff and that is all nothing fancy. I am sure we are all talking about HTC wizard/cingular 8125.

Wifi always takes alot of battery, make sure it's off, and also turn off incoming beam option in setting.
if you're reading the drain info from a program like batterystatus...give it some time after you turn off wifi for the information to refresh. wifi has a large drain on the battery...so it just might be residual information.
Hey guys,
I've spent endless hours trying to find an answer to this bug. Here's the issue, which I'm sure some of you are aware of:
When connected to Wi-Fi (at home or work), "Android OS" is not letting my phone sleep, and I continue to see "wlan_rx_wake" as my top wakelock, which accounts for 30-50% of my kernel wakelocks. For example, I had the phone off the charger for 20 minutes and it only slept for 3, even though I didn't turn my screen on once.
From what I've read, this bug has to do with certain routers continuously polling the phone due to dynamic (DCHP) frequency settings.
Solutions that I've tried:
1. Setting the IP address to static AND setting the IP address to .210 (which is above the DCHP frequency range of .199).
2. Turning off the "Power Save" mode in the hidden Wi-Fi menu. This "fix" actually made my battery life worse on my home network. I lost 50% of my battery overnight in 6 hours, without touching the phone.
3. Using the "stock" settings.
No matter what I try, "wlan_rx_wake" (directly connected to Wi-Fi) continuously denies my phone from deep sleep. And "Android OS" is always equal to or greater than "Cell Standby" on my battery log when connected to Wi-Fi.
I would be forever grateful to anyone who can shed some light on this issue. It's a major bug for me due to Verizon's data caps. I want to continue to use Wi-Fi at work and at home, but this bug is a major deal breaker. Battery life on 4G is great, but like I said, I'd like to use Wi-Fi as much as possible. I'm really disappointed in such a serious bug from Samsung. And from what I've read elsewhere, it's a relatively common problem. Yet I haven't found a solution that has worked for me.
Thanks in advance,
Dan
Do you have any apple devices on your wifi network (or windows with apple bonjour service running)? If yes then you have bonjour requests wake locks. You can confirm this using Shark for Root (https://play.google.com/store/apps/details?id=lv.n3o.shark) and eliminate that using imo's leankernel 0.5 or newer (http://rootzwiki.com/topic/31329-kerneltouchwizics-leankernel-minimalistic-kernel-v10-10412/).

Hi,
Anyone seeing this weird Wifi "Running" issue in 4.4.4? Screenshots are attached.
In wifi advance set to NEVER when phone sleeps and in screenshot clearly sees wifi turned on during "non awake" over night. Is this normal?
More detail
Keep wifi on during sleep - Never
Scanning always available - NO
Avoid poor connections - NO
Wifi frequency band - AUTO
WIFI optimiation - NO
No such issue here .. Stock 4.4.4 unrooted
Location services on?
I have the same "wifi running". I noticed that wifi shows up in my battery stats for some reason. However, I don't have the intermittent wifi on and off. I do have wifi always on though.

PsychDrummer did you notice this "wifi running" before 4.4.3?
I dont remember seeing my phone doing this b4 and I feel it has some impact on battery.

Not sure why you need to disable wifi while screen is off, but if you really need this function, have Tasker do it for you.
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.

I installed Chroma alongside with the hellscore kernel. I have found that WIFI seems to be the biggest battery drain - it should be the screen. I turned WIFI scanning off. And changed it to 2.4Ghz. But it is still the biggest. I have read some user were able to get 5+SOT using Chroma and Hellscore, I'm only getting 2+. How can I fix this?
Thanks

I usually (aside from turning scanning off) go to wifi, advanced, and set "KeepWi-Fi on during sleep" to only when plugged in. It shouldn't affect anything, but ever since Lollipop, Android is full of bugs like this. Might help, might not.

Thanks, I've changed it. WIFI bug is driving me nuts!
Still no fix, WIFI is still at the top!
