WiFi battery drain, using Continuum v5.6

I'm having pretty bad battery drain using WiFi.
Here is a screenshot of juice plotter, have a look :

I'm currently on Continuum v5.6 . I was also having this problem on 5.4 and earlier on cognition.
I don't have any 3G or gprs. Just WiFi.
With WiFi on and connected I get bad battery drain(10% in 90 minutes) even when wifi is not in use and phone is sitting idle as you can see above.
When I turn WiFi off or WiFi on but not connected, I get essentially flat curves with a battery drain of like 1-2% an hour. What gives?

I get fast battery drain just like you, with wifi on at home. My router is D-Link Dir-655. Some people say they get low battery usage with wifi turned on, so I'm beginning to think it's more to do with the router than the phone. I've had the problem from day one. My first phone developed the random shutdown issue and was replaced by AT&T. The second phone is just the same running down the battery fast when wifi is on. I have gotten in the habit of turning wifi off when I'm not using it. It's a pain, but I don't know anything else to do. I'm certainly not going to replace my router just because of it.

I have that same exact router! DIR-655.
I saw another thread in the dlink forums where a guy had that same router and the same issue. Here : hxxp://forums.dlink.com/index.php?topic=38655.0 (replace xx by tt)
Here as well : http://forum.xda-developers.com/showthread.php?t=1087278
Though he solved it by removing some HP printer drivers that were polling the LAN constantly.
Most people recommend leaving WiFi sleep policy to never, but I get better battery when leaving it to sleep on screen off. But thats just because wifi turns off about 10 minutes after screen is off so push updates like instant messages/email stop working until the screen is turned on again. (No 3G here)
I have acquired another captivate which is running the stock rom. I'm gonna run some tests on it.

The second captivate also does the same thing.
I can see a constant trickle of data from wifi using the OS Monitor App when not using the wifi and background data is set to off. Its something like 200 bytes every 3 seconds. Accordingy the wireless light on my router also keeps blinking, albeit at a significant slow rate..

Can the timeout for "Turn wifi off when screen off" be reduced to a few seconds instead of minutes??
I have a Zyxel WAP and a SonicWall router/firewall. So its definitely not Dlink only.
I see the same pattern as lurkingdevil.

I lose 5% in 10 mins with wifi on it sucks. It also depends on which apps are running in the background and which ones update like Facebook or email

I feel you..
I have now turned on 3G and it doesnt burn battery like wifi.
In OS Monitor when using 3G there is a static tx/rx value unless I do something that requires data transfer .
On the other hand with wifi on, tx/rx keeps going up even with everything off, some data is always transfering between router and phone...
I think there is some setting in the router that is causing this..

I love the whole android development game but I don't think I'm techsavvy enough to mess with my router, ill stay tuned nonetheless incase some brave soul experiments and gets results

I just switched to continuum 5.6 last night, but was constantly charging while using wi-fi. Ill look into it tonight to see if it affects me in the same way.

Ok so I dived into my router settings.
Good news is that I managed to nearly fix this issue. I have a DIR-655 , D-Link has done a great job by making a firmware emulator here : http://support.dlink.com/Emulators/dir655/133NA/login.html
Login with user : admin pass: admin
From the tabs at top choose ADVANCED --> ADVANCED WIRELESS (left pane)
Now you will see a bunch of things that have some value set to them. Here I changed DTIM from 1 to 200 . After doing this, I set wifi sleep policy to never and kept my phone aside. Checking after an hour and I had lost only 1%.
Bad news is that push notifications have gone flaky, I dont know what exactly the DTIM thing does so I'm still researching it. You can click on the "More.." link on the right pane and there is some info on it.
EDIT: I switched DTIM back to 1 and push is still not working perfectly. Can you guys check this?
Set WiFi sleep policy to never and log in on gtalk from the phone. Then send yourself some messages via another google account and see if you hear the notification sound on the phone when the screen is turned off. You might hear it the first time but try sending a bunch of consecutive messages.
For me, I hear it sometimes, sometimes I don't, but if I turn on the screen right after sending the message(and not hearing the notification) I can see the message in the status bar at the lockscreen.
EDIT 2: During my previous tests, I was logged in from my account on the pc as well as the phone. Notifications seem to work much better if I'm just logged in from the phone.

I am not seeing exact issue how much android OS usng,
looking to your screenshot, display is just 6%, means hardly you have utilised your device. it was mostly in screenoff state. Ok when you dont use your device, but OS is running in background so just OS but nothing else have drain it.
Now another thing looking to image i can say in 9hr your battery dropped 50%
it means > 5% / hr, that actually i count the measure.
In idle state it shud be 2-3 % with 3G n Data sync On. So here it is more.
anyway once let it drain completely then recharge it fully n count drain %/hr.
I am using few stuff, e.g
Autostart - just kill the app you dont using
Phoneweaver - It autometically controls my data connection e.g. just after 15min to my sleeping time, it gets turnoff my data, n swithon b4 few min i wakeup.
SetCPU - I set profile to use CPU <500 in screenoff state.

My batt seems to last longer on kl7.

Your is idle. it seem 3%/hr even using screen quite good time.

My sisters Note had same crazy issue with Android OS eating battery. Tried many things to find the culprit but only thing that fixed it was full wipe and reinstall ROM. No issues now.

il calibrate battery and see hwz it working

I have a very long time use with this firmware and very happy with the update.
I just disabled all automatic synch and the samsung apps notification and things like this.
3g is always enabled and some hours a day wifi is also enabled

Don't know if it will work for you but I had the same problem. Believe it or not a simple hard reboot, solved the issue. Was identical to mine using Android OS over 70% while screen was at 15%. Programs added and deleted were still running around in the OS until that reboot(I'm guessing). Let me know if that works.

seems better. i did a complete battery drain and recharged from 0 battery. now after 5 hours after complete recharge, im at 84%. 2 push emails..full time wifi connectivity, facebook/twitter/socialhub sync always on. 5 min phone call. and thats it.i think its better.

For those who do not realize it yet, having Facebook, Twitter, Gmail, etc syncing every minute takes a lot of power. You cannot expect the phone to be doing this for 12 hours straight.
If you have a lot of battery ussage with screen off, try to disable account synchronization and see what happens then.
You need to evaluate if you need to see every social network update on the instant, or you carry extra batteries with you, or you are able to find a place to charge every few hours.
What you cannot expect are miracles.

Hmm, something has definitely changed for me.
Up until recently I was getting two days use out of a charge with wifi, gps & 3g enabled syncing 2 gmail, 1 yahoo account plus twitter and google reader stuff. Last couple of days Android OS has gone nuts and I'm getting similar readings in terms of usage to those quoted in this thread. This morning I've drained 20% in an hour with a bit of internet use.
Only thing I have changed is updating a few apps and I've put the thing in one of those silicon protection cases but that can't be the reason(can it??!!).

[Q] Can someone explain how forgetting wifi networks improves battery?

Sorry if this is a stupid question. But i read somewhere that forgetting (deleting) wifi networks would help battery. For me, this actually worked. Im not a power user so my phone will be idle for hours at a time. Coming from an iphone (i know its not a fair comparison cuz iphone is more lightweight), i would lose ~5% during 9.5 hours of work if i never took it out of my pocket. On the gnote3, i sometimes get 15%-20% drain even with a screen time of ~30min. But after forgetting the wifi networks, drain is reduced to 5%-10% within that 10 hours im working. So can anyone explain why after a few weeks, my battery will start to drain quicker again until i forget my 2 wifi networks (work and home)? As a disclaimer, that 5% on the iphone is when i literally didn't take the phone out of my pocket at all. I am playing with my gnote3 more than the iphone (the newness still hasn't worn off for me yet), but i wanted to throw the iphone stats in as a reference.

Well I'm not certain if it actually works this way or not. But here's a theory..... If you have a bunch of stored wifi access points and aren't connected to any, the phone might be looking for those connections? But isn't it looking for wifi anyway? Maybe if you don't have stored access points it doesn't look so often? That's my theory on this situation that I've never heard before but anything is possible because it's the internet!!! The easier fix to this without deleting your wifi access points is to disable wifi all together. You can even add a shortcut to your homescreen!
If you really want to get to the bottom of this and find out what was happening I would install Wakelock Detector. Even when you're not using your phone because it's locked in your pocket, rogue apps or processes can wake your cpu. This app will tell you what's waking your device and draining the battery. If your device is rooted I HIGHly recommend getting Greenify. You can choose to hibernate apps directly from the wakelock detector app. Now how cool is that!!

I like what ^he said. Only if your WiFi is constantly on but not connected it will constantly be scanning which will impact battery. If its connected but a weak signal this will also impact battery life poorly, same as constantly connecting and disconnecting. I leave all my WiFi on all the time at home and over 10 hours of non use only drop 2% or less. However in your WiFi setting there is a setting that has an option to disable WiFi when asleep. If your always pulling your phone out to play with it and have this option enabled then every time you turn your phone on it will scan for a network. And turn back off when you turn the screen off. I am not a fan of this option and for better battery life leave your WiFi on all the time UNLESS you don't have a network to connect to. If you're connected leave it on, if not turn it off. I recommend to set it up like this.

I've got the same setup as you! It seems to work for me as you can tell by my battery stats.

What I usually do is I just take a few seconds to disable everything other than mobile data when I'm out and about. If I need to check emails I do so with a manual sync, unless it's during work or on-call hours (Gotta keep them servers running 24/7!) in which case I leave on autosync.
I try to never leave location on unless I need to use Maps, and because of that I keep all the stuff that's supposed to use WiFi even when WiFi is off disabled as well. I'm sure there's fifty ways I could automate all of this into profiles but I like the manual control over my battery consumption.
I haven't run numbers but I've kept the phone uncharged for almost two days with no problems. I was even able to make it back to home on the last 5% with three or four subway stops and plug her in before she died. And that's with the default battery.
I think it's more about overall mindfulness of what processes are running versus an insane level of finetuning for the process. If you make sure A) that WiFi is disabled, and that B) WiFi is *REALLY* disabled, meaning no scanning for networks or being used for location services, then even if you have fifty networks saved it won't scan for any of them.

Wifi battery drain on MM

Anyone having issues with wifi constantly destroying the battery even when off?
I've turned off wifi scanning and location mode is device only and yet when you look at battery stats wifi is still on.
Only fool proof way of turning it off is having all aforementioned settings in place and then disconnecting from wifi while I'm still connected instead of leaving it by moving out of range (leaving my house for example).

Hello, I hope I can help. I have the same issue the day after I received MM OTA, that wifi drained me more than 10% in the morning when I haven't done anything online.
I tried googling. In addition to location and scanning settings, there is one more you can try:
http://www.naldotech.com/having-problems-with-marshmallow-wifi-battery-drain-how-to-fix-it/
Now go to Settings > Backup And Reset > Network Settings Reset and reset settings.

The on screen instruction said I will lose all wifi settings, but turns out I don't need to enter the wifi and encryption keys again. I performed all these steps in one go and the problem disappeared the next day, so I don't really know which switch actually did the job. A week has passed, no more battery drain now and the battery usage is far better than I anticipated.
Hope this is helpful to you.

No dice my friend, still draining. I've disconnected from WiFi while in its range and am avoiding turning it back on and using 4G only
Wish someone would figure this out. Battery or WiFi is a pretty bad choice to be forced to make.

Have you really tried reset network setting, as I quoted in my earlier reply, and reboot immediately? If this doesn't work, do you have time to do reset factory default? A complete factory reset can sometimes be the last way out. No guarantee though.

I was having the same problem + cell was getting hot too often. I did a factory reset and the 2 issues were solve. You might need to try that.

Question Pixel 7 Battery Drain in Phone Idle

I've been noticing huge battery drain on my Pixel 7 after the March update. No particular apps are draining the battery, phone idle alone does it.
I thought after the June update, it will make the battery backup better but I think it made it even worse. Last night I charged my phone to 100% and slept by turning off WiFi and mobile data. I even kept my network type to 3G to avoid background activities from 4G. And waking up after 5-6 hrs of sleep, I found my battery to be 89%. Screenshot is attached below. This is very disappointing. I bought this phone on February. It has not been a year and this is the performance I get from a flagship?
Clearly, this is not normal. Phone Idle draining 78%(of the 11% actual battery drain) of my phone's battery is crazy. I used to get 2 days of battery backup before that March update. And now I can hardly survive 16hrs. Please help me with a fix.
Notes:
Country: Bangladesh
I use dual SIM. 1 physical and 1 e-SIM.

Factory reset, then be careful what you install.

You didn't use anything on the device though. The phone is idling more than doing any other task. So of course 78% of that small amount of battery drain is going to be due to the idle because idling is what is doing 78% of the time. I really don't see any issue here. I mean you only lost 11% battery over 4 hours and that first 15% drains quicker because lithium ion battery drain isn't linear. That first 10% always goes faster than the rest of the device. If it really bothers you, I would suggest changing the doze parameters to wear it disables the sensors on the device until it's unlocked.

Also, I just noticed that you have no mobile data on either SIM card. The phone is looking for a signal constantly and not getting it, that alone will drain battery, not to mention using dual sims has been known to affect battery life as well. Is the phone in airplane mode in that picture?

You aren't alone. I've been fighting the same issue with the battery drain since March. Up until the June update my excessive battery drain was showing as "Mobile network" but now it shows as "Phone idle". Strangely it drains the most when not in use. I've already done a factory reset and ended up with the exact same issue instantly.

It may be worth trying to disable the "adaptive connectivity" setting and see if that helps. I live in a weak 5g area and my phone was constantly switching between LTE and 5g causing signal drops and battery drain for me. I turned it off and it helped with both issues.
Settings, network & internet, scroll down to the bottom.

Not in airplane mode. I turned off Data then why would it constantly look for signal?

I guess I should have asked first, I wasn't sure if you turned data off or not, I guess that's what led to the airplane mode. What about in developer options? Is mobile data always active still set to true?

Anyone with this issue my best suggestion would be use some kind of doze optimization mod. I know nap time is kind of outdated but some things still work correctly. I believe all of it does except for the GMS does magisk module. If you scroll all the way down to the bottom there's a setting that says wait for unlock. That keeps the phone in deep doze mode until you unlock the device, which also keeps the sensors turned off as well. Another option is diamond John's app Temefi. In the search box, type in doze, and you'll see a place where you can choose from several different Doze profiles. For this you need root, but if you're not rooted I would stick with nap time which just needs some ADB commands entered

i think it's a bug, i have no drain but look at the screenshot
"telefono inattivo" is phone idle, same percent but 1hr and more compared to yours, strange, indeed i've no drain
i always keep data, wifi and bluetooth on, since i work in a place where there's no 100% coverage of wifi, and bluetooth for smartwatch connection

have you tried safe mode?
