After upgrading to LSC, I noticed that "Keep wifi on during sleep" when set to NEVER, no longer work. Under battery, wifi is constantly ON.
Any one has a fix for this ?

I was playing around with the Wi-Fi sleep policy settings and I am little bit confused how it really works.
The default setting is something like: "turn off wifi when screen is turned off".
So as I understand it it should disable wifi when the screen is turned off.
However when I checked my device list at my router it seemed that my n1 was still connected through wif, even after the screen was turned off. Only after 5-10 minutes wifi was really disconnected (when I turned on the screen again the wifi symbol in the top bar appeared after some seconds). I read somewhere that there is a difference between disabling wifi and disconnecting wifi?
BTW. the wifi sleep policy is supposed to save battery because it is said that 3G in idle mode requires less power than a wifi connection, but I read that with the nexus one the opposite is true. so what's the truth?
It's normal for the wifi to disconnect after several minutes of inactivity once the screen turns off. As for your very last question, I don't know... but I imagine that idle 3G is less power intensive than active wifi, otherwise it wouldn't be the default option...
strange thing..
if i set "keep wifi in sleep" to never it just stays on.
i got cpuspy to see if it really goes into deep sleep but the wifi just stays on.
i know i had this problem with customrom JB on my LG optimus black but now i have official JB on my XT and got the same problem here.
i need to install a app to control the wifi like i want it too..
(i always set wifi to disconnect when the phone enters deep sleep, my experience tels me that 2g data drains less battery then wifi)
however i didn't really test drain level of wifi/2g data on my XT.
I have a strange problem. I set the 'Keep Wi-Fi on during sleep" to "Only when plugged in" but I see that Wi-Fi stays always on, also during sleep. In addition I noticed that the largest battery consumer is Android OS. Any ideas what's wrong?

Under Wifi Advanced Settings, you probably have the option for "Scanning always available" enabled. This keeps wifi available for location services, and makes it look like it's always on to the power monitor.
No. It is disabled

Your battery usage doesn't look off. Android OS is almost always the biggest battery consumer on mine unless I'm using the phone heavily. wifi is typically 3-4.
I easily get through a day on a single charge. Usually I've got between 20-40% left at night depending on usage.
As for wifi I don't know. Perhaps there is another app keeping it on. I would try turning all location services off and see if that changes anything.
I'm curious why you'd want wifi off. generally it will default to the mobile signal which will use a lot more power. only reason to turn wifi off is if you don't have access to it.
Guys, tonight I decided to switch off mobile data and WiFi when I went to sleep. Now noon, when the battery was almost over I decided to analyze some attention to battery depletion statistics and realized that even turning off the WiFi it continued to appear that spent the whole night on. Also, see that shortly after I slept network operator turned yellow. How to explain? My carrier has the much more stable network overnight just by reduced use and the absence of network overload.
He had the 3g network enabled, less mobile data.
It happens to me too. I guess it's only a visual issue, I dont think wifi is draining battery life.
Due to Wi-Fi scanning always available. Its actually keeping the Wi-Fi on if that option is chosen in Wi-Fi advanced options. Turn that off and you'll see that your Wi-Fi actually shuts off.
I'm suffering from excessive battery drains on Note 8, Nougat 7.1.1. The battery drain is excessive when on idle mode/when the phone is asleep. I have installed BetterBatteryStats (gave it all permissions) and tested with different settings for a couple days.
My findings:
I strongly believe the issue is with my wifi.
Day 1: I kept wifi on, turned off "adaptive wifi" and "wifi power saving mode" and set "keep wifi on during sleep" to always. Battery drain was very excessive at home. In BBS, wlan_rx_wake and powermanagerservice.wakelocks were very high and phone didn't doze much. When I left home and went to the library and was connected to my school's wifi, the phone dozed, and the two wakelocks mentioned didn't occur any more. In fact, from the screenshot you can see the two flat regions are those when I was at the library, and the downhill regions are when I was home.
Day 2: I kept wifi on, turned on "adaptive wifi" and "wifi power saving mode" and set "keep wifi on during sleep" to never. No change. The results were just like day 1. Excessive wakelocks and battery drain. In fact, funny enough, the wakelocks occurred more often as if "wifi power saving mode" was doing the opposite of what it was supposed to.
Day 3: I turned off wifi completely, and was on cellular the whole time. Battery performance was amazing. Lost 5% over 10 hours, and I actually used the phone during this time. I made calls, surfed the web and texted. Additionally, the are no excessive wakelocks, and the battery plot is nearly flat the whole time.
In conclusion, I am really confused. At home, wifi kills my battery. At school, wifi doesn't do anything weird. It makes me feel like this is more than just some setting on the phone or some bug with Nougat. Maybe some networking issues with my wifi at home? I was hoping I could better understand my situation by getting help here. Any feedback is welcome. I have screenshots from each day so tell me if you think they'll be helpful. Thanks.
Make a factory reset... try that, it makes my stars better.
Could very well be caused by Wifi calling. Try switch off Wi-Fi Calling at home.
I remember having this issue in past with my Note 5 icw bad Cell reception at certain locations.
But wifi calling is always on, regardless of what wifi I'm connected to. It must be something specific to my wifi at home.
