I'm sure there are others who have experienced this problem. Even though I show no wake locks my phone drains at an unacceptable rate while on my Wifi at home. My phone can have a 60% battery when I go to bed, and be almost dead by the time I get up. The only clue that shows up in Android System Info or Spare Parts is network usage by '0' which is something with root access.
This is happening regardless of Rom. I've tried stock, Syndicate Frozen, Urban Fury, Bonsai, Stock Plus, and maybe another I'm forgetting. They all drain the crap out of my battery with wifi on at home so obviously this isn't a rom issue.
This leaves me to believe that either something on my network is forcing data to my phone keeping it from deep sleep, or the router itself is the cause. Turning on my phone to 3G, my battery life is spectacular overnight. It deep sleeps like it's had a case of beer with a bottle of nyquil as a chaser before bed. 1% an hour.
So, I've ordered a different router to see if that's the issue. I've googled my current router which is a D-Link DIR-655 and seems like others have had similar battery drains using that router but no one can emphatically say it for sure is the router. Guess we'll see when the new router arrives if it is indeed the DIR-655. Otherwise the next step is disconnecting everything else that is connected to my network (3 computers, 2 printers, XBox, Wii and a Blu-Ray player. I just wanted to point out to anyone else having issues with wifi and weird battery drain, that it may not be the phone that is the problem.
I too have massive battery drain when using Wifi. It doesn't matter what Wifi network I'm attached to (work/home/friends/etc), I burn about 10% + per hour on idle; whereas on 3G is burning only ~2%/hour on idle. On stock, Wifi was my battery saving grace.
I've just given up on using Wifi for daily use. I use 3G for everything now.
I hope the newest version of SFR (whatever the new one will be called) will remedy this problem I have. I haven't posted about it in the rom thread since I had a feeling it was just my phone or another bad flash in CWM.
I've been using that OS Monitor app to try and find the problem. On 3G all the network interfaces have static receive and send amounts as long as I'm not doing anything that requires data. Connected to my home wifi, there is a constant trickle of data.
When I let the phone sit overnight, there was over 4mb of data received, even if I turn off any kind of auto syncs on the phone.

Don't know if this will work for you but you can try. In the wifi settings click the menu button and select advanced then set the wifi to never sleep. I know it's counter intuitive but I went to sleep last night at 61% and woke to 57%. Wifi has been fine for me since changing that policy in the wifi advanced settings.

Mine has been set at never sleep since I got the Epic in September, and I double-check after each custom rom flash. Good looking out though.

Same here. Mines always been set to never sleep.
Edit: I just tested my phone on my work's wifi network. CPU Spy says it's going into deep sleep just fine. OS monitor shows a static data received/sent number once I was connected. Obviously something about my home network is the problem.

That is my general experience, too. These settings usually keep my WiFi usage low overnight.
But some nights, inexeplicably, I will wake up to find a large battery hit from WiFi. I don't think it is my WiFi router's problem, unless there is some outage duirng the night I am unaware of. Come to think of it, I had that problem last night but did not investigate early this morning before I left. When I get home, I will check with my laptop to make sure my router is running.
I have noticed this too and in particular over the past few days. I'm on the latest bonsai build which does have amazing battery life on 3G but now wifi does draithe battery much more than 3G. This never happened before. I have had my wifi set to never sleep. Any other suggestions?
Obviously haven't tested it overnight yet, but I shut down my one laptop and the constant data trickle immediately stopped. Right now it's looking like something my computer is running might be the culprit. Going to leave it sit overnight to see how it goes.
I found the cause of my drain! Narrowed it down to something from my laptop as when I shut my computer down at night, the drain would go away. The culprit was the HP Printer software for my wireless printer. Once I uninstalled it, the drain went away. Noticed in resource monitor that HPZinw12 was sending a constant stream of data from my computer. Why in the hell it would be also sending to my phone keeping it from sleeping seems pretty odd, but I recommend if anyone else who is having battery problems over wifi and happen to also have an HP printer, you might want to look into this as well.
I'd also add that my solution to getting rid of the problem and still being able to use my printer was just to uninstall the crappy HP software that came with the printer and add the printer through the control panel and let windows 7 install it. It doesn't throw on that HPZinw12 file that apparently polls the entire network constantly.

Since I have been experiencing similar symptoms intermittently and I also have a WiFi printer, I have tried to eliminate this as a potential cause. (I don't run an HP control app on my laptop, but already map the printer directly in Windows 7 like you suggest.)
In my case, I still get the excessive WiFi battery drain, and low battery level upon waking, sometimes overnight. But other nights the problem does not occur. So lately I have made sure that my laptop and printer are powered down before bedtime. And like you, a always have my WiFi sleep policy set to "never" and have a strong WiFi signal. But last night I still had the problem, and awoke to find the battery drained to 45 percent instad of its typical 90 percent.
Interestingly, I noticed not only high WiFi battery usage but also high "Cell standby" usage attributable to the well-known Time Without Signal problem -- and this despite my habitual use of the Airplane toggle workaround, which usually works.
Somehow, something caused both WiFi and cell radios to go crazy overnight.
BTW, I run a stock, unrooted Epic.
So far with SRF v1.1.1, my Wifi is back to normal.
On my work network, I've dropped 4% in 3.5hours with my work email syncing every 15mins. So that's pretty good usage given that sync interval.
I also do not have a printer at home, so the printer bit wouldn't have been a cause for me.
While the printer thing took care of the biggest problem for me, I still don't get as good of battery life overnight leaving my phone on WiFi rather than 3G. There is still something my computer is doing that wakes my phone up occasionally, but at least I'm not going to bed with a 70% battery then waking up to a dead phone. At least I have it narrowed down to one computer (total of 3 on my network), as when I shut that particular one down battery life for my phone is back to 1% an hour while sleeping. If I had to take a guess at this point, might be something with media sharing as I use that one as my primary location for music/videos to stream via Windows Media Center.

How do you know it is your computer? Have you tried just turning it all the way off?
Do you watch the services running on your phone? I routinely stop the DRM service, for example.
Except for the mysterious episodes when I experience this intermittent problem, my overnight battery usage is typically about 1 percent per hour.

I've tested over a few nights with a mostly full battery off the charger and reset the timer on CPU Spy. The nights I shut that computer completely off, I get very little battery drain and the phone is mostly in deep sleep according to CPU spy. When it's on, the phone shows a good chunk of CPU at 800mhz and more battery drain.
Hey, I am trying to figure out why my battery drain is so high. Part of it is the display (trying to work on that too) but I see that my "phone signal" is quite bad. I have a feeling that this is draining my battery.
I have attached my battery stats. Do they look normal. And does the phone signal look normal or below normal. I think it is worth noting that I almost always have 4 bars of signal so I am not sure whats going on. I use my phone in Canada on the fido/rogers network (i believe it is the same as At&t in the states). Is there another radio I can flash or something if this is not normal (which will still work with my phone/network)?
Thanks a lot
Reports are that using 3G a lot drains the battery immensly.
Try switching to use 2G only and see how that affects your battery life.

I dont think it is worth it to pay $30 a month to use 2g networks. I will try to turn off the 3g radio when on wifi though. And maybe only turn on 3g when i need it. As for the phone signal bar. Is it the same or worse than what you guys are getting?

It already works this way. Wifi is going to be your best bet to lessen drain if available (both in standby and when using data - just make sure you have the sleep policy set to never).
If you have poor signal you are going to murder your battery - no way around it. The radio will boost power (Gain is adjusted automatically) in an attempt to get a better signal - and constantly search for a better one. So if you are bouncing between no service and 1 bar or even with just a weak 1 bar signal you are going to see atrocious battery life. There's not much you can do there except potentially switch to SIP in those times if you use a SIP provider.
If you are sitting with 4 bars then you should be seeing decidedly better battery life. What is the actual time the display was on in that screenshot?
I use 3G and its fine. What radio are you using?
the choices are: JK8, KB1, KB3, KD1
you can find them on the dev forums

I agree. you're a pretty heavy user So far different radio doesn't drain battery, but only the difference of data connection speed cap.

Yes I do love android (been tinkering around since the g1). I do realize that I am a heavier user than the average person but it might also be that I recently got this phone so I am using it more.
Aside from that, does everything else seem normal?
"Android System" should not be taking such a high %. It should be about 1-2%.
There is (was?) a bug that causes high cpu usage (and shows as Android System) when wifi is on, but not connected to a network.
Another thing I can think of and is something I've experienced, is that sometimes you get an IP address from the mobile network that has a lot of noise, that is, it's an address someone has likely used p2p programs with and there are lots of connection retries. You can see it because the green arrows don't stay dark for more than a couple of seconds, and it kills your battery quite fast. Reconnecting to get a different IP address is the only solution...
Also, bluetooth may be a factor...

Blutooth is always off unless I need to use it (which is rare). I am not sure how to make my mobile network connect to a different IP adresse, would turning it on and off do the trick?
Being in area where there is low/no signal also causes my battery drain to increase by a lot! Which sucks cos where i live i get either 1 or no bars of signal.
I'm having an issue where my S4 is just running hot all day long and my battery is getting thrashed. I've used CPU Spy and see that its mostly up in the 918MHz band and not much deep sleep. I thought I used to see it run mainly at 384MHz and deep sleep for the majority of the time.
I've used wakelock detector to try to find the culprit, but have had no luck. Reboots, clearing the cache, nothing seems to alleviate this. There is quite a bit of Sprint Network Vision going on in my area and my phone signals are bouncing around, but even on WiFi its terrible. Speaking of WiFi, I constantly connect and disconnect from WiFi Access points at my work. Eternally frustrating.....
so my two questions are:
1) please tell me what your phone sits at most of the time with CPU Spy
2) do you constantly see issues with disconnecting WiFi on your S4?
details: I'm running STOCK, NOT ROOTED with Nova Launcher, no mods.

It's the WiFi at your work that causes the connecting/disconnecting issue. The WiFi at my school does this as well, I will be connected, then disconnected then connected, etc. But at my house, friend's houses, and anywhere else it will stay connected until I disconnect it.
As for the CPU Staying at 918mhz, try using BetterBatteryStats to see what is causing your issues. or even try GSam Battery Monitor.

Yes, I work at a University, but I'm on a network that uses typical WPA2 authentication and not the PEAP authentication, I had IT set that up for me so I could test it. The kicker is that this only happens on my S4. When I had the S3, this did not happen. Eitherway, I think it has to be AP related as you say, it works on my home WiFi just fine and any other single point WiFi.
I've tried BBS and haven't had luck tracking down the misfit application.
I'm going to factory reset this afternoon just because I'm probably due for one

Are you rooted? Highly recommend you wait it out and DL/flash Sac's ROM v7 (should be dropping before the end of the weekend!!).
I have been experimenting with the S8 trying to extract the max battery life and after disabling a lot of junk "Bixby included" and taking my phones battery drain over night to a very respectable 2-3% overnight on LTE with AOD off and QHD. The real problem is the drain because of WiFi overnight which in my case is a 5Ghz AC signal from Netgear orbi
The Netgear orbi is configured only for 5Ghz AC and all my devices link to that network. There is no 2.4Ghz used at all neither is b/g/n used so its a static 5Ghz AC connection everywhere.
My S8 which uses 2-3% overnight on LTE with data ON consumes 7-8% overnight with similar configuration but this time with WiFi ON overnight.
That's correct. Many apps want us to update through WiFi and will hold untill you enable it. Otherwise it happens in the background.
I have wifi disabled in standby.
I'm also on 5Ghz btw.
Verstuurd vanaf mijn SM-G955F met Tapatalk
I have disabled auto update for applications since day one.
I have a Netgear R9000 which actually supports AD. My Tab S3 and S8 are connected to it on 5GHz constantly and I see no battery drain.
Not necessarily draining. But wifi enabled in standby tend to use just a bit more. If it really drains a battery overnight something else is going on.

What about over night how much battery percentage do you lose?
I am sure that apps don't update since I have disabled auto update so what else can be happening to get 7-8% drain overnight
Why not use gsam to compare what apps are draining how much with wifi on vs wifi off. then you might at least know if its specific apps that are using the wifi more or whether it is just system using it more. you wont narrow it down any other way.
Of course actually getting gsam to show the app drain is another matter since it STILL keeps randomly losing the ability to split the apps out (about 80% of the time) and then randomly gaining it back again every now and then, and this is after using adb to give it the permissions it needs (it seems to forget it has the permission a lot of the time). I emailed the dev months ago but there hasn't been a single update since.

Thanks for the suggestion using gsam already but I found it very buggy as you have pointed out but over night it says two things have used the most power that being in descending order:
Kernal
Android System
Other than this others have used less than 1-2%

Phone: Mi A1 Stock - Oreo 8.0 April update
I consistently charge the phone when battery level is around 30% to around 85%.
I recently changed ISP's and a new router was installed. It is a Huawei dual 2.4/5GHz fiber router that replaces an old Huawei single band fiber router and has 2 separate SSID's.
Since that change, my battery life has taken a significant hit and drains MUCH quicker than it used to. Where it would normally last 2-3 days, it now lasts about a day. Battery drain during screen off time is almost twice as fast as previously. For instance, I charged the phone to 90% Yesterday, less than 21 hours ago. Battery is now at 53% with only 21 minutes of SOT!
I've tried:
Staying connected to the 2.4GHz band
Staying connected to the 5GHz band
Turning off the Always On setting for WiFi that I have always had on
Nothing above seems to impact this situation in any way. If anyone has any ideas or solution for this, I would appreciate the help.
Regards,
Maybe the reason is a different transmit power and receiver sensitivity of the router. Maybe your new route requires a higher transmission energy than you old router.
In addition, some routers allow to use 2 channels in parallel, which would also mean higher energy consumption
I am assuming it is something like that. The signal strength is the same on both: full signal. The new router is considerably faster than the old one in throughput, even on the 2.4GHz band. But wow! Now I am thinking that the A2 needs a bigger battery! I really did not expect this type of hit from changing routers! Might be something for others to consider if they are planning a change.
Thanks for the response.
you updated the firmware on the router?

As far as I can tell by Huawei's screwed up website, the router has the latest firmware. Huawei's website is NOT user friendly and it took me quite a while to even find the firmware area! REALLY bad design for a customer website!
But thanks for the suggestion. It did make me look it up, or at least try to.
@KB_Thailand: you could consider using some custom-firmware for your router.
Typically you would gain more options in configuring your router
Even with the standard firmware, you could play around with various options to find out which configuration and option suit you best
then try to change the wireless band, maybe other router automatically used a less crowded band, this new one not do this and you end up use a band who is used from many people who live too close to you.
Thanks to both @riccetto80 and @Tiemichael for the suggestions. I did look at the router setup and also looked at network diagnostics. The router appears to be set up okay.
Signal strength for the WiFi bands is between -45 and -50 dBm everywhere in the house, and noise is between -88 and -91 dBm.
Both bands are set to auto select, and both bands are using unused bands in the area, and are the 'best bands' according to the diagnostics.
There are only 3 other WiFi routers I can see from my house, and 1 of those belong to my Time Machine. The WiFi router is not using the same bands as any other WiFi.
Transmission strength is set to 100% on both bands.
When I went to bed last night, I had 41% battery. This morning, 7 hours later, I had 20%. The screen was off and the phone should have been in sleep mode, yet it drained 21% battery. The usage in Settings->Battery shows Launcher3 as eating a lot more power than might be expected for a phone in sleep mode. I have tried using ONLY 2.4GHz and then ONLY 5GHz, which made no difference in battery consumption.
I am at a complete loss as to what is going on.
Regards,
maybe is not about wifi! did you tryed a foce doze app like naptime and a app-sleep app like servicely?
It is definitely something to do with the change in ISP/router. I was out of town the last 2.5 days and the phone went back to acting as it normally did before, lasting over two days on the charge, even while switching WiFi networks often. The hotel had 6 networks in both bands, and depending where you were on the property, one of them would be much stronger than the others. No issues whatsoever with battery drain on either band. I came home about an hour ago, and the battery has already drained 6%. This is after only using 3% since 0600 this AM until I got home.
@riccetto80 No, I haven't tried the apps because it wasn't doing this before and the trip proved it is not something that went bump with the phone hardware. I just need to figure out what is going on with the new router, as I am almost positive it is the problem. I have a couple of other things to try over the weekend, so hopefully will arrive at some kind of understanding at what the problem is. If no resolution, I will try the apps and see if they make a difference.
I *THINK* I might have figured this out. It may be a two part problem. I went into settings and set the location to Battery Saver vs. High Accuracy, set the Security to turn off the settings to not lock the phone for my home location and on my body, and went into the router and set the Beacon Period to 200 from 100. I tried 1000 and DTIM of 2, and 500 and a DTIM of 1, but that made the internet connection quite laggy, so backed it off to 200 and 1 on DTIM. (100 and 1 is default) These changes SEEM to have slowed the battery drain down considerably., only losing a few percent points in the 4 hours since the changes vs. 6% in an hour. It's funny because these settings were still active when I went out of town, so it may have something to do with the keep unlocked for the home location and the new router.
I'll report back if these don't fix the problem.
Follow up post:
The issue is some sort of conflict between the router and the Stay Unlocked at this Location setting. I went back into the router and set the Beacon back to 100, the default setting, but left the Stay Unlocked Setting off and the High Accuracy Location setting set to Battery Saving. The phone is now acting like it did previously, so I consider the problem solved. Where before it was using 6% in an hour, I have only used 5% in 6 hours with these settings.
So, if you are experiencing battery drain issues, one thing you might wish to try is to set Location to Battery Saving (middle selection) and make sure the Stay Unlocked settings are off. It is really no more of a pain to hit the fingerprint reader than to hit the power button to turn on the screen.
I hope this helps someone.
