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.
Hi, I live in a place where there's very poor network coverage and my SGS often looses signal. And here's the problem: when I check battery consumption in the settings I can see that the phone is often awake (for about 1,5 hour overnight) and looses battery like 3% an hour even when I don't use it and is supposed to be asleep. Is it possible that it is searching for available networks during that time and that is why it is awake and eats battery?
I do not have data on, nor wifi or gps. I'm running SLIM 3.3 with 0.67b Devil.
Thanks in advance.
I've been running marshmallow since the stock images were posted and I always got very nice battery life with doze. As in, I wouldn't have to charge the phone until the next morning. Since last week, however, cell standby is using significantly more battery. Yesterday, I took the device off the charger at 0900, and by 2100 I was already at 25% battery. Screen on time was only 2 hours, and cell standby had more usage than the screen. No matter my signal quality, it seems cell standby is eating my battery. Phone isn't even showing as awake! I also am always connected to WiFi and using T-Mobile WiFi calling.
I know a few users have reported a similar issue since marshmallow, does anyone have an idea of why cell standby is killing battery even though time without signal is 0? Time active is also always under 20 min. Since I'm using WiFi calling, I'd think the phone wouldn't even be searching for a voice signal anyway.
My signal has been worse than abysmal since switching to Marshmallow. I uninstalled Fit, Pay, and Google+ and it got better strangely enough but i still have issues from time to time...

The same happened to me, at the begining with marshmallow (chroma and francokernel) always more than 5h SOT and easy deep sleep... but now, the last night at 1:00AM battery was at 100%, at 5:00AM was 84%... and no wakeloks... i'll take some screenshots
Same here. I swear the battery is draining faster but no wakelock issues.
Plus I believe there is an issue with the signal reporting. Where I know that I get full signal the phone can report zero bars. Switch to airplane mode and back, then suddenly the signal displays correctly!
+1 My signal is terrible anymore, and I certainly was much better on the preview images
At my desk at work, same spot I sit my phone everyday would be in the mid 80s and right now it sits at -103....hit airplane mode and it resets....for a few

I'm having the same issues. Overall, pretty solid battery life but cell standby drainage was high. Been searching forums with no such luck. Sounds like it might just be and Android issue I have to hope gets fixed in an update? I'm using T-Mobile wi-fi calling. I'm in areas with strong LTE signal, but compared to my old phone, the amount of "bars" I'm seeing seem lower and sometimes non existent, although I spent no time without signal.

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
