I always used to have much higher battery drain when on wifi than when on 2g/3g when idle with the same sync settings etc. When the screen is on and i am using the phone, the drain seems to be identical. Is this normal? Is there a setting or something that prevents the wifi from draining the battery too much when on idle?
Mind you that the same problem has always been there for me even before i was rooted...
Thanks in advance for any responses
on my phone is the same.
i believe its normal cause wifi sends a signal. 2g/3g uses the same like the network.

Thanks for responding
The reason i was asking is because i have read some people said that they had better battery life with wifi on than with mobile data...

Go into WiFi Advanced settings and have a look if Best Wifi mode is on or something like that. I haven't used Sense in a while so I can't remember what it's called exactly.
For me the difference between having that on and off was about 65mA which is huge compared to around 5mA, this is in standby.

I have "best wifi performance" off mate...
To tell you the truth when i had it on the drain was about the same and also I did not notice any major difference in the actual wifi performance...

Oh yep I had the exact same issue which went away after I moved to CM7. So pretty much only advice I can give you is to do a backup and try a different ROM and see if the same thing happens.

Really odd problem here - as of a couple days ago, everything was working perfectly with my galaxy nexus. I decided to jump over to CM10 (was on codename android, IIRC), right after I think there were some new commits to AOSP.
From here on out, my phone would never enter deep sleep when connected to wifi. Any wifi hotspot - the ones I've been using, a hotspot I created from my desktop - the icon would show the phone constant receiving data via wifi. Using better battery stats, over about 5 hours on my desk, 4.5hrs were spent with a WLAN_RX_WAKE kernel wakelock with my phone sitting at 350MHz instead of deep sleep for that time.
I tried a bunch of different kernels (stock CM10, franco, imoseyon, etc) both new and old versions, but the problem was still there. I tried clean flashing a rom, and only installing better battery stats. Same thing with all kernels.
Factory restored google stock images to BOTH ICS and JB. I still have the problem. Tried disabling google location services. No dice. Tried a couple basebands, but I'm pretty sure that only affects cell/data performance, right?
I honestly have no idea what is going on. I've been on this hotspot (campus wifi) for months now without a problem, and now this. Some threads say that this is caused by DHCP requests from the router, but why would I have not seen this until now? My idle drain was at about 1-2% per hour before this, now it is close to 10-15%.

This is literally the EXACT SAME problem I'm having...I wish someone could properly explain why this is happening and how to fix it.

Not sure if you've tried this and it helps but maybe you can try Network Log or Shark from the store to diagnose this?
Network Log doesn't show up with anything, so the wakelock shouldn't be caused by a rogue app.
Shark, on the other hand, after about 10 seconds of logging, netted me about 300 DHCPv6 'solicit XID' requests. There a bunch of different sources from these requests, they just seem to be other devices on the network pinging my phone to see if it's a DHCPv6 server...?
I've seen some suggestions on other forums to mess around with the router settings, which I can't do because it's campus internet.
Since you've tinkered with rom/kernels etc on phone without any seeming change, it's feasible that there's been some change recently on the other side of the equation namely the network settings of your campus wifi? Maybe your University's tech department has implemented something new etc? Have you tried asking others with wifi enabled phones if they are experiencing this as well?
Found this here (pretty sure you've come across this if you've been googling abt this issue but posting anyways)
"Another more elaborate solution if you rely on that network a lot, is to purchase a wireless bridge or gaming adapter and connect it to your apartment wifi and then connect your own wifi router to that. Then the gaming adapter would get the dhcp IP from your apartment (so who cares if it is renewing it constantly) and your router would treat the connection just as if you were connected directly to an internet connection. Then configure your router for static IP addresses or if your router does not cause issues with DHCP then you don't need static IPs."
from http://rootzwiki.com/topic/16134-kernel-wakelock-wlan-rx-wake/
I know I had an issue with some wlan rx wakelock thing last year but I cannot for the life of me remember how I got rid of it or what changed
Hmm, seems like an okay solution but my friend's devices don't seem to show the same symptom, and since I roam campus alot, a wifi extender wouldn't be ideal.
Bump. Any other ideas?

I am seriously ripping my hair out from this goddamn wakelock ****.
I wake up at 9am and have to charge my phone by 4pm because it's at 16% with 40 minutes of screen on time. Seriously? This is a JOKE.
I've checked with BetterBatteryStats and CPU Spy. Both confirm the phone keeps sitting at 350MHz when it's supposed to be sleeping, as well as wlan_rx_wake keeping the phone awake.
I've set my phone to receive a static IP from my router (DIR-655) but it doesn't help. I really don't know WHAT to do. I've downloaded shark to my phone, sniffed packets, but haven't been able to get anything useful out of it since there is a LOT to sift through (unless you know what you're looking for - which I don't).
This is by far the worst bug/issue I have ever encountered with my phone and it is seriously getting on my nerves. I will be forever greatful to anyone who can help me pinpoint the issue and make it stop.
Also, i REFUSE to "go buy a new router" as it's bull****. This is a bug people experience only sometimes it seems and NO ONE has a fix for it. I read somewhere about a fix being implemented in some kernels but they were for other phones, never found anything like it for the GNex. If anyone knows anything about a fix like that, please show me the way.
I already checked for rogue apps, there were none keeping wifi awake. I've even tried with a totally stock, newly flashed phone with stock kernel and everything. NO extra apps installed except shark, CPU spy and betterbatterystats sideloaded. I didn't even input my GMail to stop the syncing. It STILL KEPT MY GODDAMN PHONE AWAKE.
I am SERIOUSLY desperate. Considering just selling my phone and opting for something else if this continues, it totally cripples everything.
/rant over
turn on WiFi, Bluetooth, and GPS, for about 30seconds, then turn them off. put your phone to sleep, then check if you're going into deep sleep. CPU spy is a good app to check if your hitting deep sleep.
Change wireless network encryption? Wpa2, tkip+aes, aes only, tkip only? Wpa?
Change wifi channel?
Edit: scratch that. Try disabling 5ghz band.

I had a similar issue, it turned out it was Dropbox LANSync in my home LAN. I used an experimental forum build on my PC, so it could be this, but in the end I turned LANSync off, since Android doesn't make use of it anyway.
So try this if you have Dropbox running on your network clients.

A quick update, I just tried all the suggestions in the quotes in my previous post but to no avail, still getting the wake locks. I'm seriously going crazy.
Turning wifi off did let the phone sleep, but that was expected as the wake lock is related to wifi. Nothing else has worked. NOTHING.

This issue appeared again for me, it obviously also helps to disable the NETBIOS on your Windows PC network adapter. There are guides for that online. Also get the "Network Log" app in the Play Store, it shows the traffic so you can see which one's are for the kernel (wlan_rx_wake is a kernel wakelock).
Also uPNP feature in router can cause all kind of weird behavior. Better block it from router's firewall.
Sent from my slimbeaned GNex
What baffles me the most is that all of this shouldn't be needed. I shouldn't have to disable netbios and do things to OTHER devices just so my phone sleeps. This is a jellybean issue imo, I never had these problems on ICS.
The experiments continue, updates incoming.

I also suspect the major issue was that my wifi channel was the same as the ones around me. When I changed it, the wlan wakelocks went down significantly.

5 Ghz band is disabled when you enter Wi - Fi - advanced - Wi - Fi frequency band ... It's set to auto by default, you try either 2.4 or 5 ghz on manual and check if that helps ( incase you didnt already )
Does anyone have any news about this issue? I have the same problem and I can't find the solution. I made several test without any good results.

The ROM I'm on is ParanoidAndroid 3.99-RC2 on an AT&T Galaxy S3. I've been having battery problems for awhile on this phone, but after upgrading to this, it has just gotten much worse. I take a look at BetterBatteryStats and it says my wifi is running all the time. I don't have wifi on most of the time, and I've reset the phone and it is still occurring.

For wlan_rx_wake, the research was saying this error is triggered by settings and/or background activity on 1 or more particular wlans you connect on (not by anything on your phone). Different posters saw it draining their battery on their school, work or home wifi networks accordingly.
I took 2 approaches: Since it was my home network, I disabled the UPnP service on my main router. I also separately configured a static IP (one that is outside the range of automatic addresses) on my phone for the home wifi connection using the "Modify network config" command available by long pressing an SSID in the list on Wifi settings. It worked. 1.4% / hour overnight drain is restored. (It had risen to 4%).
Both approaches isolate the phone from some types of network broadcast activity that triggers excessive wake time.
For me, seems working this operation
Go to WiFi settings-> Advanced-> Uncheck "Scanning always available"

There is a setting to auto switch to your data connection if the wi-fi signal is not strong / reliable that you can turn off. Try that.
this is a pretty serious issue that doesnt seem to be happening to many people.. its killing me right now it just dissconnects with no warning.. and it seems not many people are actually experiencing this.. im calling tmobile tomorrow to get a replacement to try and see if it is ok or not but im pretty pissed to get a refurbished unit for a phone i just a montha go

i wonder if this is a samsung thing or a T-Mobile thing? We've had Galaxy S3, S4, SII, Note 1. the only one that is "rock solid" is the Note 1 [Tmo version running mod'd stock rom, not JB].
We were able to get the S3 "much improved" but still has a relatively weak ability to maintain signal across multiple AP's or especially with Bridged WIFI AP's [it will "hunt" between physical devices and fail to deliver].
I would suggest you lookup any one of MANY threads on the topic with the S3 especially as there were people that worked hard at it on that one - lots of those deployed in the wild and a huge number had that issue.
turn off scanning.
turn off power management for the WIFI radio.
i wish there was a mod to turn off the network but that would probably kill the "calling" feature altogether. if it has a strong signal on the cell network it ain't going to do wifi calling period.
Data connection has nothing to do with WIFI calling. I use the note 1 a lot and rarely turn 'on' data. its happy on wifi no matter what.

Ya know I think it could be rom related, it seems like with all the international roms the wifi is great and I don't even have to turn off the power saving mode and never drop the wifi connection. With all the MI7 built roms it seems to drop wifi and have troubles. IDK maybe its just a fluke :fingers-crossed:

You tried both options?
First
1. Navigate to System Settings
2. Connections > WiFi
3. Menu > Advanced
4. Uncheck "Allows Allow Scanning" and "Auto Network Switch"
Second
1. Dial *#0011#
2, Menu > WiFi
3. Power Saving Off
(Kudos to QuickVic30, I hadn't seen this before)
After doing both, you're still getting the problem?
if you have adblock plus definitely this is the problem, i had it for a while and noticed affecting my wifi. uninstalled issues gone! replaced it with adaway
I also had huge problems making WiFi calls, my router had auto update off, once I updated the router I have ZERO issues, so updating router firmware absolutely works for some people and it's relatively easy to do at least with home router. On the other hand when I switched WiFi power saving to OFF as suggested in other posts, it did absolutely nothing, except increased drain on my battery. I had 20% battery drain overnight (about 7 hrs) and my phone would go dead in less than 1.5 days even without being used. After I changed that setting back, now my battery drains 3% over night and lasts me 2 days with moderate use and has still 60% power left. I do realize different people may have different issues and therefore different fixes, but updating firmware of your router does work in many cases, no question about it and the old firmware didn't affect at all my 2 laptops, couple tablets and 2 Galaxy S3, only Note3 had the issue, so it is hard to believe, but it WORKS. And the power drain that I suspect switching "wifi power save" to off created for me, is beyond reasonable, so maybe people should be aware of it as well.

My Verizon note 3 that I switched over to t-mobile over a year ago, suddenly started to drop all wifi connections. After a brief connection it rescans then drops. I read your thread and when I dial *#0011# , im assuming you mean "call" there is no menu for wifi. What is the dialer? The phone keypad? Any help is greatly appreciated.
So, I was on latest MIUI China beta before. Somedays ago, I flashed the Resurrection Remix 6.0.0 (06.03.2018 build). Battery was draining fast. I checked battery usage and there was this ”Mobile Network Standby” which was draining the battery. It even consumed more power than Screen and Android System. I thought it was some bug on RR. So, I flashed Lineage OS 15.1 (05.03.2018 build). Everything was fine here too. Except that ”Mobile Network Standby” thing. It was draining battery on this ROM too. I tried L OS 15.1 12.03.2018 build and RR 6.0.0 10.03.2018 build. That bug still present in these ROMs too.
I tried possibly everything to fix that issue. I've tried following -
1. Network Setting Reset
2. Turn off Data always on in Developer Settings
3. Turn off VoLTE (I don't even use LTE here)
4. Clean cache via TWRP
5. Turn off WiFi scanning during sleep
6. Turn of Location Services
7. Turn off Google play Services wakelock and background running via Privacy Guard
8. Finally, I clean flashed both ROMs
But, Nothing has fixed the issue.
on Nougat 7.1.2 ROMs everything is absolutely fine. There's no draining issue
PS - I used stock kernel with CN Firmware 8.3.1 and 8.3.8
Is there any possible fix for this issue? Anyone else having this issue? Any updates on fixing this issue in future?
Sorry for my English btw
Thanks
Update: Using the ForceDoze (root method) app reduced the battery drain. But, it didn't really solve the problem
Try the app "ForceDoze", helps with almost any battery drain. Does require root though. Another explanation could be that your reception is bad for whatever reason, so also check that. Also flashing a newer GApps might help.

I tried using sim slot 2, a sim duplicate, also I have migrate my network carrier... still the same...
Since I read it also happens in miui roms and it could be firm related issue I flashed oldest firm required by LOS15.1, that as luk said is 8.1.4, and after switching off WIFI it still drains my battery...
I don't know why this happens, and I don't know why it is happening just to a few of us but is totally annoying...

This problem occurs due to incorrect work with VoLTE, including after various ways to disable it (in the settings, through Build.prop, etc.) and is relevant only for some cellular operators.

all won't be fine. I've tried that. though, draining reduces on 3G network. but, mobile network standby still drains battery. no fix so far. not even a clue, what's causing this drain
I only get a noticeable drain on the train, so I guess it has something to do with connecting to, or scanning for, network masts.

I think i know whats happening. When i first installed los 15.1 on my s5 it showed 2 sims when i only have 1 sim port. A reboot seemed to fix the issue and now shows 1 sim. However, i also noticed that without signal, mobile network standby is at 72% draining battery. At this point im thinking the phone is searching for network. What if that even though there is full siignal on lte, the phone is continually searching and scanning even though its connected to cellular network?? Thus giving us this massive battery drain.
I have an Umidigi A1 PRO and had a similar issue, Mobile Network Manager battery drain. I contacted Umidigi and they replied to me:
"Ok, please go to 'Settings --> Security location --> Location (under Privacy) --> Scanning' and disable both Wi-Fi- and bluetooth scanning. That scanning function uses both bluetooth and WiFi (in any phone) even if they are turned off."
This reduced battery drain considerably and now overnight, with wifi switched off, battery usage is between 2% and 3%. Even in day with wifi switched on drain is what I would expect of any mobile. There must be a reason why this option is not placed under 'Network'. I haven't tested out the above (dual sim), but will try adding a second sim and see what happens as the the Mobile Network Manager battery usage is still above normal.
Regards.
I have the same Cell Standby issue.
However Wifi & Bluetooth scanning are disabled.
I have also set my preferred network to 3G since I don't have an LTE contract yet.
I'm currently using a Galaxy Note 4 (SM-N910F), with the current Resurrection Remix Oreo build (RR-O-v6.1.0-20180712-trlte-Official).
I sure hope somebody figures this out.
