Ok, I have seen this on 2.3.5 builds of CM7, Deck's ROM and OMFGB. What is going on with wifi on 2.3.5? It's causing some kind of wakelock apparently. Look at the right hand side of the battery graph and compare the "awake" to "wifi" time. I had my wifi to sleep when the screen turns off, so it went away when wifi was turned off. But then if I connect to wifi again with the screen off, it causes wakelock. Is this a known issue? I have tried googling and can't find anything about this. Surely I can't be the only one.
On Sense roms I can leave my wifi sleep policy as "never" and it doesn't cause any issues.
I'm using the CM7 nightly build 180 (2.3.5). I'm using Tiamat Kernel SBC. My WIFI sleep policy is set to never. It's been unplugged for about 8 hrs 45 minutes and connected to my WIFI. It's been on standby for the most part and it's at 99%.
WiFi totally unrealiable on the AT&T Atrix 2 (MB865)

I too am seeing all sorts of issues with WiFi on my Atrix2 (MB865) which is also running Android 2.3.5. As a matter of fact, I have TWO of these, because my wife got one also, and it has the same problems. To be specific, both phones will drop 128Kbps streams and fall back to 24Kbps, if the alternate slower speed is offered. This constant dropping of audio stream is the most annoying problem, but the phone also will spontaneously disable WiFi. After manually re-enabling, it can take up to a minute to reconnect to the AP (the happens at home and at work).
When connected, a speed test might show something like ~100Kbps down. But disabling and reconnecting a few times will help get it back to a good ~20Mbps down again. Sometimes when connected ad showing a FULL STRENGTH WiFi status icon, I am still not able to get any data whatsoever, just as if the WiFi is not even enabled. Examining this with WiFi Analyzer shows that it detects no AP's whatsoever, even while the status icon shows a FULL STRENGTH connection. Again, disabling/enabling can correct this issue.
Just to prove it's not my home AP, I have an old HTC Hero running a CM7 nightly build from 9/1/11 kernel 2.6.29-6 (which is also Android 2.3.5).
My old HTC Hero connects quickly/flawlessly and holds a constants steady 128Kbps stream all day without fail.
Why can't these carriers (AT&T in this case) put out a reliable Android build. I can't help it, but my paranoid mind makes me think it could be purposefully done to force customers to use precious bytes form their costly data plans. They certainly would have no incentives to make WiFi work efficiently.
Anybody got an ETA on CM7 for this phone?

Anyone else getting this after the update? Cell standby is absolutely killing my battery when WiFi is on. Turning it off, I'm (kind of) back to normal. I've done a factory reset, forgotten my WiFi then cleared the cache, and it's still the same. My phone was running perfectly fine before, now I regret installing the update.
I am not. I have better battery when on Wi-Fi.
Samsung Galaxy s6 Battery Drain
i have the same problem with my galaxy s6, since I made the update the cell standby is killing my battery, i use lte all the day because of that..
Battery life has been abysmal for me since the update as well. Samsung needs to fix this ****.

Turn wifi on, let it connect, then go forget your connection. Reboot into recovery, wipe cache, then reboot your phone. It has worked for me so far. Cell Standby still shows up on the list but I'm only losing about 2% battery/hour with moderate texting.
It is an issue with WiFi! I have tried all the fixes found in a google search for "S6 Edge Cell Standby Battery Drain". Here is what I found from my testing:
Day 1: All day with WiFi on, with good cell coverage. Had to charge twice throughout the day, and Cell Standby was at about 40% each time I put it on the charger. Charged overnight to 100%
Day 2: All day with WiFi off, same location as Day 1. Battery never drained past 30% with the same amount of use. Cell Standby at the bottom of my list at 1%. Charged overnight to 100%
Day 3: All Day with WiFi on, using WiFi calling. (VoLTE turned off) Same result as Day 1. Had to charge multiple times throughout day and Cell Standby at 40%.
VoLTE turned off, cleared cache, factory reset. Tmobile device running 5.1.1
I think the issue here pertains to what apps are installed and not necessarily running actively.
I you have any or several social networking apps ( Fb, Skype, instagram, twitter ) you don't even have to use them because they are always busy in the background unless you setup auto stop.
I have no social networking apps installed or active so my system runs very lean, have seen cell standby but never higher than 2% or 3%.
I have ran my WiFi all day while at home and connected to a network and have gotten a full day with 20% to 10% left on the battery.
Now results would be different if you travel and aren't connected to a network.
I'm in a metropolitan area with great lte 4g signal and don't use WiFi that often and just using 4g I have gotten great battery life to the tune of 30+ hours with battery to spare.
Do some app inventory.

This has worked for me so far. I'll use the day to test whether or not it's a successful workaround solution. Thank you :good:

I tried this, unfortunately didn't work for me. Battery drain is making me hate this phone with each passing day.
My issue is NOT app related.
I Factory reset, then ran two days of testing.
After factory reset, I also cleared cache again.
No social media apps configured.
Turned on phone from reset and setup google account only.
No apps installed, aside from factory apps.
My tests are with VoLTE turned off and WiFi calling turned off.
*Day 1 - WiFi off completely*
100% charge at 0700, used it all day at work and home. Cell Standby used 1% total and I ended the day at 2300 with over 50% battery remaining.
*Day2 - WiFi on all day*
100% charge at 0700, used it all day at work and home. Cell Standby used 43% total and my battery died at about 1530.
T-Mobile support stated it was a known issue, Samsung could not "troubleshoot" it properly and just wants me to ship it in for "repair". They did suggest taking my device to a "Samsung Experience Shop" in my local Best Buy. I did and they factory reset the phone. They also informed me that this is an issue with the S6 Edge, and that the factory reset is not going to resolve my issue.

What can we help with: Galaxy S6 Edge, "Cell Standby" is draining my battery FAST, if I have WiFi turned on. I have factory reset device, cleared cache, turned off VoLTE, tried with and without WiFi calling turned on, it is ONLY an Issue if I am connected to a WiFi network. Doesn't matter if it's 2.4Ghz or 5Ghz.
T-Mobile : Hi!
T-Mobile : I'm sorry to know if Cell Standby is draining your battery fast when connected to WiFi. I'd be very happy to help you out!
T-Mobile : Is this for line XXXX?
You : yes
T-Mobile : All right, I'm checking on a few things. One moment please.
You : thanks
T-Mobile : You're welcome. May I have your phone's software version please? Here's how to check:
You : 5.1.1
T-Mobile : From the Home screen, tap the Apps icon.
Tap Settings.
Scroll down to 'System,' and then tap About device.
Read the baseband version on the phone.
You : I am on the most recent firmware, based on the T-Mobile support site
T-Mobile : Great! Please bear with me.
You : Baseband is G925TUVU2COF6
T-Mobile : I appreciate that, one moment please.
T-Mobile : Thanks for waiting. I checked on this further and see that this a known issue that Samsung is aware of and is hoping to get fixed by next update.
You : any timeline for this issue resolution? I don't want to use up all my data, just so that my phone will stay powered on for an entire day
You : If I turn off WiFi, my battery performs normally, and can get through about 2 days without charging ... If WiFi is turned on, I can't even get through an entire day
T-Mobile : My apologies but there is no timeline as we speak yet. One recommendation I see here is to turn off Smart Network Switching in your WiFi settings. Here's how:
T-Mobile : From the home screen, tap the Apps icon.
Tap Settings.
Tap Wi-Fi.
Tap MORE.
Tap Smart network switch.
Tap Off.
You : That is turned off
T-Mobile : Oh, I see. I apologize but we'll need to wait until the next update from Samsung. You may contact them directly at (888) 987-HELP (4357).
You : I have ... they stated I needed to send my device in for repair.
T-Mobile : Oh, we are unable to replace the phone since the issue is software related. This all started after the 5.0.1 update.
T-Mobile : This should be addressed by next software release.
You : it started the day I took the phone out of the box, 3 weeks or so ago. Got an update to 5.1.1 in the 2nd week, but the issue remains
T-Mobile : I understand where you are coming from. WiFi bug fix should be included in next software update. We are still standing by for more information from Samsung as to approximate of the release.
You : thank you
T-Mobile : You're welcome! Your patience and understanding is truly appreciated. Anything I may have missed for you today?

I too have great 4G signal here, and if I leave WiFi off, I also get great battery life. The issue is when WiFi is ON. No matter what, I MUST have access to a charger if I use WiFi at all throughout my day.

That makes sense, especially if the wifi radio is scanning all the time looking for networks to connect to.
We should have the option to "turn off" wifi scanning and turn on when needed.

Although not ideal, turning off wifi fixes the issue for me.
Any news on this issue? My phone immediately start to lag and drain out the battery when I connect it to a wifi. On cellular it works fine though. This should not be a hard one to straighten out!

ok i have same problem. and only 1 way for fix it is turn off LTE. go to mobile networks >>> network mode >>> choice "WCDMA only"(4G only). it will be fine. For sure.
this problem is because software android 5.0 from GG. if can please go to SS website and report. let them fix it.
Hi, I have the nexus 5x since Oct 2016.
With wifi, BT or poor coverage, y consumption is high. Minimum of 1,5%/hour. With mobile data 0,2%/hour. Perhaps with poor coverage is normal, but I don't understand why it happens with Wifi (At home (2.4Ghz and 5 Ghz) and at work (5Ghz)). I have tested multiples cases.
I have had 7.0 (stock), 7.1(stock), 7.1.2 (Dev), without root and with root + (Franco kernel or ElementalX kernel) + naptime. I have desactivate Wifi scaning on location. I never see the flat line in battery graph with Wifi.
I use the app "gsam battery" to see the battery graph.The kernel and Android system are the first app suckers, I think it's normal. I don't see anthing unusual in battery graph. The mobile go to sleep mode correctly.
What would be the problem? What new tests I can do?
Thanks
Question: Are you using Project Fi, or any other carrier that allows for WiFi calling/texting?
To clarify: I don't think Project Fi is the culprit, but I may have a solution that I've been testing.
A common complaint that goes back to my N5 running Kit Kat. The fix was to force the device to only use 2.4Ghz Wifi, however since 7.0 Google has removed that option.
Changing router's or updating the router firmware has helped some in the past but not for me.
Does your device Doze properly on a mobile data connection also? And does wifi occasionally idle properly, say when switching back and forth between wifi and cell data? That's the case for me currently, and you know something's wrong when a 3G connection idles better than Wifi.
I'm not using Project Fi, or any other carrier that allows for WiFi calling. My carrier is vodafone, a normal carrier.
I have tested a router with 2.4Ghz only, but the problem persists.
Doze works correctly with mobile data connection and Wifi. I can see the mobile go to sleep mode correctly in both cases.
But in idle mode, wifi use a 1.5%/hour and mobile data 0.2%/hour, but I don't see nothings strange in the graphs or stadistics.
What I can I try?

Ya sounds exactly like the issue I was describing. The fix used to be to force the device to only pick up 2.4Ghz connections but Google took the option away ever since 7.0. Being on a network they only transmits 2.4Ghz doesn't help as the device is still listening to and picking up 5Ghz signals.
There is no known fix that I'm aware of. I don't think Google considers it their problem, they would likely say it's a router compatibility issue and tell us to upgrade our router firmware.
I'm having an annoying issue since upgrading to Oreo.
When disconnecting from some WiFi networks the mobile data doesn't turn back on. No amount of going in to airplane mode fixes it. A reboot is usually required.
It doesn't occur with all WiFi networks.
Has anyone seen this? Or know a fix?
I'm running Oxygen 5.0.1
No one seen this?
Hey, I lose mobile internet connections quite often.
Haven't noticed a trend, so can't say if it's Wifi related. Neither toggling aeroplane mode or mobile data on and off makes it work again so I just end up resetting the phone.
I'm sorry I can't offer anything useful, but I can at least say you're not alone!
This is happening to me as well oxygen 5.0.3 , total pain I've got tasker to switch on hotspot and mobile data when I enter car but Data doesnt connect and have to reboot phone
Hello guys. I suppose I'm not alone in this. My phone losses over 20% every night when connected to wifi network. I tested with wifi off and mobile data (4g) on, and it losses only 4%. Drain is not caused by any apps on my phone, and my wakelocks are ok(tested by GSam Battery Monitor and Wakelok detector). Phone does go into Dose mode overnight. After long period of testing and searching internet I did full wipe data/cache and install stock rom from oneplus site, and install just a few apps from playstore. It was disappointing when wifi drain continued after all I did. Also, when I turn on airplane mode, phone losses 2% overnight, so my conclusion is that wifi causes drain. If you guys have some advice for me, it would be helpful. Thank you!
Same issue here. I have tried everything (clean installs... Formatting data... Multiple roms and firmwares etc)
This is with scanning off and location off. It's Oreo related for sure as the issue dissappears when I flash Nougat

I hope there will be software update soon to handle this problem.
Hi
I have the Same issue on my Huawei p20 lite with Android 8.0. I think it's definitely the software
I noticed that the Wifi drain only appears if there are many wifi networks around.
At home we have 3 networks around and my phone doesnt lose any battery over night.
At my girlfriends place there are like 25 networks around and my phone loses >20% overnight.
Realy strange.
Maybe it has something to do with wifi scanning in the background?

Nah.. Think it's the wifi configuration on the router. When I switched ISPs, I was given a new router and the drain disappeared.
There have always been 4 wifi networks that show up on my devices.
