After the recent update for battery issues the wifi is blocked out while on airplane mode. This prevents use of wifi if you turn on airplane mode because of poor cell tower reception. It also prevents use of services like Gogo while on a flight. In areas with poor reception the battery drains very quickly if airplane mode is not selected. Unfortunately it now kills wifi.

Ever since I did the LG update from B to D and baseband to 405 I have had issues with my wifi. Two things,
1. After a while wifi looses my home WAN network and will only reacquire it if I turn off the wifi then turn it back on. This did not happen before the update. It occurs whatever wifi sleep setting I use. I am consequently using much more 3G data than before.
2. Wifi now uses ~50% of my battery usage. Overnight it chewed through my entire battery. When I woke I thought I had BSOD but instead my entire battery had been used.
Any ideas what the problem might be?
cheers
Airplane mode on, WIFI on , sleep policy off.
18 Hours / 40 Percent
WIFI 42%
Phone Idle 35%
Display 13%
I ran my OG droid at home with wifi on since it came out and usage on the OG was typically 2-3% of battery. What gives?
Thanks,

My battery is not the best either, and I think it's the WiFi scanning too frequently (if not constantly). I need to run more tests, but I feel like if you are not connected to a WiFi signal, you should turn WiFi off immediately. That's what I'm seeing anyways.
I have my phone switch over to WiFi when I'm @ home (I use Locale to automagically do it for me) and shut off when I'm away. I also have the search for open networks unchecked in the WiFi settings. I figure the constant scanning has to be eating up some batt.
I suggest using an app like auto wifi toggle just checks for wifi every so often then turns it off if it is not found and if you have no wifi connection it turns off as well.

Open Network notify is turned off, and I do use the native wifi toggle. Wifi on at home, airplane mode for the 3g/LTE enabled.
Hello I need some app that will turn on Airplane mode at night or atleast turn off Data connection. For specific time period. I found out that data are consuming too much of my battery at night.
Last night I had a problem with my home wifi (phone couldn't connect--Authentication error). I rebooted the router and it connected. Then I noticed an hour or two later that my phone was warm and the battery drained about 20%. I charged it fully and went to bed. Six hours later and the battery was completely dead.
Cell Standby is using 60%. I wiped the dalvik and cache in recovery and it's still using 60%.
The phone is on CM13 RR (6/22).
It's a Marshmallow bug that occurs when on Wi-Fi and connected to LTE.
You can alleviate this issue by using an app that automatically switches to 3G like Smart Network (Xposed) or GravityBox's smart radio (Xposed), or by turning mobile data off entirely when on Wi-Fi. By doing thia, Cell Standby won't show that "drain." However, MMS (but not SMS) texts will not be sent or received if mobile data is off, with the only exception being Verizon's Message+ app, which can send and receive via Wi-Fi.
There's some "debate" as to whether or not it actually has any impact to battery life or if it's just a visual reporting issue. Me personally, I see zero negative effects of the Cell Standby "drain." If I turn mobile data off, or use the 3G "fix," my battery life is basically the same as when Cell Standby is showing the "drain."
More in-depth analysis of by Cell Standby "drain" analysis here.
I believe I have solved the problem. I reflashed the .49 update and everything went back to normal.
I Have notice that battery of note 8 drains quickly when switches for both WiFi and Data are turned on.
I turn both on for the purpose that when I am out of range of WiFi, data will turn on seamlessly, and when WiFi is available, it will switch back to it.
With both switches on, even when only WiFi is in use, the battery seems to drain quickly.
Battery life is tremendously improved when only WiFi or data Switch is on.
Any ideas as to what is the problem?
Main element to drain battery after screen is Device Idle.
Attachment: idea as to what I am talking about.

If you leave the WiFi enabled all the time. Your device will constantly scan for a network, which you are signed onto. That drains the battery. Unfortunately you need to disbaled WiFi connectivity when you are not gonna use it to preserve power.
You can disable mobile data connection while you are connected to WiFi. This is done throw developer options
