Since a few days I have a very interesting problem. I have my SGS3 for a few weeks now and I was very impressed with its battery life. Until a few days ago.
Then I installed PhotoEditor (from Samsung itself, using Samsung Apps). When opening Samsung Apps it installed an update. This also included the Push Service and some adservice. After that my battery drained really fast. After uninstalling all three apps (PhotoEditor, Push Service and Adservice) this high battery drain went on.
I then performed a hard reset. And even then, without even installing any apps it drains the battery too fast.
However, it only happens when I'm connected to a wifi network. 3G is always off. When wifi just stays on, but is not connected to a network, battery life is very good and nothing strange happens.
When wifi is connected, and when looking in the battery settings menu I can see a very high Keep Awake time in Android OS. However, it doesn't show which process actually is causing this high Keep Awake time. So I installed BBS, but this doesn't really give me a clue either.
Anybody having an idea what could be causing this battery drain? Even after a hard reset?
I'm not rooted, just using the stock firmware. All help is really appreciated!
Edit: I'll post some relevant screenshots soon.

Try flashing the latest firmware via Odin..and see what you install next time..also you can try changing WIFI sleep policy from the advanced options in WIFI..
I have the exact same problem!! Very frustrating. It started when I did and ota update so I decided to flash a custom rom. I have since then done numerous hard resets and re flashes to try to fix it. No luck.
I am now on omega v11.1 with the stock kernel and it still drains. I've installed better battery stats and this is what it shows:

I can see the biggest problem is Google talk. But what are the others? My wifi is set to never stay awake when sleeping.
Very annoying as I was having great battery life for the first month of use but then suddenly this starts happening.
This needs to be solved as I see I'm not the only one.
Edit: I don't even have gtalk installed because it was part of the bloatware removed by omegas rom.

Android OS draining battery, ONLY when connected to WIFI
Please find my screenshots attached. I discovered that my battery is only being drained when my phone is connected to WIFI. WIFI is on all the time, but when it's not connected to a network, nothing strange happens.
In the battery history details the first 9 hours are "recorded" when WIFI was on, but wasn't connected to any network (I was traveling). Then you can see a steep decrease when I got home again, and got connected to my WIFI network. This decrease continued than for the night.
In the BBS stats you can see that something from Google talk is listed quite high, and it is a large wake time.
However, it must be noted that although the phone has a huge awake time according to BBS, this can't be seen in the battery history of the phone itself. It seems like the phone is almost only awake when the screen is turned on, as it is supposed to be...
So it looks like when WIFI is connected something is happening, and that is draining my battery...
Any help in interpreting the above results is really appreciated!
Edit: I'm not logged in to Google Talk...
I'm only syncing WhatsApp, and Gmail (contacts, calendar and mail)
Last, but not least: The orange download arrow is on continuously. So it's downloading non-stop?! How can I find out what it is?

No drain on other WIFI
Back home, at my own WIFI network I don't experience this battery drain, and everything is normal. However, on my friends WIFI and my work WIFI network battery drains much and much faster. I didn't change anything in the settings meanwhile...
Any thoughts on this?
Edit.
Sorry wrong thread
Nobody any idea why WIFI drains my battery when it's connected to certain networks? While on other WIFI networks battery usage is normal? And more important: why it suddenly drains the battery on these first networks, even after a factory reset while a few weeks ago this didn't happen and battery drain was normal even on these networks?
Same problem here, battery drain is enormous when phone is connected to my home wi-fi - 20% in 7 hours. Download arrow is always flashing, android constantly d/l's something at 4-10 kb/s. Of course, I've checked anything - from mail client to android os - nothing. Tcpdump shows broadcast packets, some ARP packets, 25 out of 273 packets are directed to me - 6 from my mediaserver, others are from Google's servers - nothing that can explain constant download. Any advice?
UP1:
Frozen/deleted all google and samsung apps - maps, gmail, gtalk, google+, samsung push, firmware update, etc. No changes. Disabling google backup and autosync did nothing,
Get a data usage app from play(onavo is good) and that should tell you what is using the data
I've now been on my home network for almost two days, and without changing any settings this is the result. (see the attachment).
As you can see the phone has been connected to WIFI all night, and no such drain can be seen as in my first post. In other words; without changing any settings on the phone battery drain is normal on my own WIFI network. However, on two other WIFI networks there is a huge battery drain when connected while the phone has exactly the same settings.
So, that probably means it isn't due to some kind of app, but due to the WIFI network, or more specific to the combination of phone and WIFI-network. Looks like the WIFI network is always pushing data to the phone, to the system Android OS (as far as I could trace using Data Monitor). I know there have been some issues with WIFI on the SGS3, but they were mostly about disconnecting, and therefore different than this one.
What is most annoying is the fact that a few days ago battery drain was normal on all WIFI networks. Only after updating Samsung Apps (which included AdService and Samsung Push Service) and the PhotoEditor it started draining fast. However, after deinstalling these apps and a factory reset the problem persist. Even when disabling almost all apps no improvement.
Edit: An explanation maybe, but only for "open networks". But not a real satisfactory solution.

Do a hard reset, install 3g watch dog pro (not just mobile network.. it can also check wifi data traffic) and install all of your regular apps. Follow wifi data traffic apps by apps from watchdog..
Or second answer: install android firewall app, and choose apps which are really need internet access... dont allow the otherones.

Doesn't help. Even after a factory reset, without adding my gmail account or installing any apps it drains the battery when WIFI is connected. The orange arrow is almost always lit, like it's downloading something. The strange thing is that this doesn't happen on another WIFI network, it only happens on some.
These apps tell me that it is the Android System itself which is downloading/receiving the data.

Multi-band Wi-Fi?
I don't know this for a fact, but I've read some things that lead me to believe the issue may (again, not confirmed), MAY be related to the recent ~LG8 OTA push. The root (no pun intended) cause is related to how the SG3 interacts in 802.11n band Wi-Fi networks that utilize multi-band (i.e. 2.4Ghz combined and 5Ghz running simultaneously).
One of the "features" of ~LG8 was to remove Advanced options for Wi-Fi networks, switching the connectivity logic to "automatic." If a GS3 is in a multi-band 'n' Wi-Fi network, it MAY be switching back and forth between bands, thus chewing up battery without actually pulling any data.
This is unconfirmed, so don't shoot the messenger. Can any of you validate whether or not the Wi-Fi networks where you see excessive drain is indeed a multi-band 'n' network?
No, im facing drain issues with 2.4 GHz network.
im also have this issue.

Modem doesn't change Wi-Fi. Drivers are in kernel.
Because you're facing issues on only some of your Wi-Fi networks I suspect it's the infamous broadcast/multicast issue. Try a custom kernel. Siyah have patched it I think. Had similar problems on my redundant network before patch.
Sent from my GT-I9300 using Tapatalk 2
Already on latest Siyah, no changes.
What is the infamous broadcast issue? There are a lot of broadcast packets in my network...
On open networks it is really bad. When I connect to such a network it asks for me to log in/accept the terms. After accepting the terms my (standard) internet browser redirects me to my own homepage. However, the orange download-arrow keeps lit up. After a few minutes the phone gives this notification that I should accept the terms again. However, when I'm redirected to the browser there is nothing to accept, and my internet is still working properly.
So it looks like this "acceptation of terms" is a major issue, like the phone doesn't remember I already accepted the terms. Is it caused by the browser? Or something else?

1 hour 12 min screen time and so little battery left is a bit less than normal. I get around 4 hours of screen time before my battery dies.
There seems to be a huge amount of time where the screen is not on but the phone is wide awake, which means high battery consumption. If you're talking on the phone or listening to music at these times when the screen is on, then it's normal. If not, then there is some app or widget keeping the device awake.
try freezing "wifi sharing" as well. Not sure if that helps but i see alot of wifi battery use.
Thank you for your reply.
In the case of calls, it is only 30 min as indicated by the pic above.
I do not listen to music on my phone at all, neither I have many widgets, the only widgets I have are: Modern Clock, Google Search, Accuweather.com widget set to refresh every 3 hours, Month widget.
also I have the windy weather live wallpaper and it is set to refresh every 1 hour.
So you mean that is not normal for stock configuration?

I am not rooted and do not wish to TBH.
however, I try to be connected to wifi for data as much as possible, as I have read somewhere that it does have better effect on battery than cellular data connection, that is why you see a lot of wifi.
One question please. How do you get the first screenshot ?
I can see wifi activity that suppose you have wifi enable all the time, is that right? As you can read, wifi sharing and other stuff around are battery consumers. You can read litening thread about this.
Other question, did you disable fast dormancy *#*#9900#*#* ?
And samsung apps disable notification even in wifi mode...

I have read about process freeze and other root activities, which I am not interested in.
I have also read that fast dormancy has no real effect on battery life, have you tried it yourself and did it work effectively? what was the difference in your case?
Thank you for the samsung apps thing, I will try that and see.
Just to clarify, I am not complaining about battery life or anything, I am just sharing my experience to make sure that whether this is normal or I am missing out on anything.
Regarding the fast dormancy stuff, I have read this thread and got contradicting results that confused me (http://forum.xda-developers.com/showthread.php?t=1111581&page=4) I did have the "data network stuck" problem, but after factory format and with a little over 44 hours of uptime, I still didn't face it. I am afraid it is going to pop up again if I alter this setting. besides, fast dormancy is a network feature, I will check with my provider to see if they support it or not, although I get H+ in most of the locations I have been in while using data.
Has anybody confirmed that wifi sharing is the culprit, or even Ms exchange emails?

@OP- If you haven't already done then calibrate your battery with Battery Calibration app by Nema from Market.

I am using litening ROM since v1.1
When version 1.5 was delivered, litepro rollbacked the delivery during one day or two days. Because, I was using v1.4, modem ke7 was the version I used and I tried to flash only the modem version to upgrade to the latest one (kf2). The benefit was important not only with data up but also when I put my phone in plane mode. But, I saw also a great improvement when I flashed the version 1.5 of litening with wifi sharing removed.
I don't really use data all day but for me with many samsung apps freezed with titanium backup (social, game, ... Hub). I have a great improvement with this rom. I will try to activate data and wifi all day tomorrow to see the battery impact.
without any custom roms, root related activities or any other warranty voiding stuff, do you guys still think that my battery utilization is abnormal with the amount of usage I have?
I have been experimenting with battery life and different scenarios, uninstalled Facebook, Twitter, Skype, fring and nimbuzz... However battery life didn't increase.
So decided to switch off data completely, and only work on wireless whenever available.
Looking at the screenshots below, i still see awake times with screen off, especially in the last periods...
My question is, how can I check what is keeping the phone "awake" while screen is off?
Thank you in advance.

You can check it with Watchdog but it will also drain some battery. So use ATK, you won't have a non-synchronized Awake and Screen On bar.

Ms-exchange is the one for me... I then switched to "Enhanced email" and it had fixed battery life quite good..
download CPU SPY from the market and see if your phone is going into deep sleep.
reset the timers, then one by one, change variables until you find the culprit.
Which is better for the batterylife, 3G or Wifi?
At home and at work I'm connected to Wifi, but yesterday I noticed when I turned off Wifi and used 3G instead 3G seems to use less battery. However, this could also be because of several wakelocks I had when I was using Wifi.
I would understand Wifi is better for heavy internet use and 3G for push messages, but I couldn't find an answer anywhere on the forum, sorry if I missed it.

Hi there!
Wifi uses a lot less battery life, especially if you browse or do anything.
Having wifi ON always uses a certain amount of battery life, now, if you're receiving emails, downloading, browsing, it easily makes up for it. The reason for this is that Wifi is a "local" communication signal. It's for short distances, therefore your phone doesn't have to emit that strong of a signal, nor does it use up that much battery to receive. So Wifi is the way to go if you're just going to use it even a little bit.
3G uses more energy because of the radio spectrum itself and the distance and having to maintain it. It's true while having wifi you also maintain 3G, but you're not emitting constant data, it's just the "I'm still alive" packet to your operator.
Summary:
Use wifi if you're going to use your phone on the internet even a little bit. Turn it off when you don't have wifi near you, otherwise it'll be looking for a new wifi hotspot and that'll drain some battery.
Don't use wifi if you're not home.
Thanks for the clear answer!
Glad to have helped
New problem
The last 2/3 days my batterylife decreased. My phone was awake most of the time even though the screen was off and this hadn't happened before. After installing BetterBatteryStats (BBS) I could see the process wlan_rx_wake was on top (about 6,5 hours of the total 10 hours the phone was on).
My first thought was some app was responsible for this, however when I turned off Wifi and started using 3G again my batterylife seems to be normal again. Checking BBS the wlan_rx_wake seems to be renamed to deleted_wake_locks.
The last things that changed just before the problems started occurring was installing the Facebook and Twitter app, and updated to the latest ICS Vertumes theme (I was on 1.5 and now I'm on 1.6). So I uninstalled the Facebook and Twitter app but this didnt help at all. I already uninstalled Google Maps. The only thing I haven't tried yet is changing to the original theme, but it doesn't make sense this could be the solution.
Any ideas?
I had the same problem with the twitter app, it kept waking my device so i uninstalled it and use Ubersocial now.
I use Juicedefender (Ultimate version if you want to pay)
Juicedefender can turn off your wifi and 3g when your screen is off. It can be set to ping your data/wifi every few minutes if required to check emails tweets.
But Twitter nor Facebook is the problem. When uninstalled the problem still exists. Dont want to turn off wifi or 3G when the screen is off as then my mail or whatsapp wont sync.
Read something that it could be the type of router, but this isn't it as well. I've got the problem at home, work and at my parents house. All different routers.
Think I might just do a full-wipe and hope that solves it..
Before you do a full wipe try freezing Wifi Sharing and Wifi Sharing Manager with Titanium or Bloat Freezer Free to see if that makes a difference.
Sorry I recognize twitter was not an issue for you, it was the app that first alerted me to my issues about the wakelocks
LocationManagerService
Hmm... LocationManagerService is active over more than 4 hours. What could that be? GPS and the Google location stuff is already disabled..
logout of maps and check if that helped.
---------- Post added at 12:22 AM ---------- Previous post was at 12:17 AM ----------
wakelocks by apps that needs to sync can still be left even if u have deleted the actual apps that's requesting on-line data.residuals i would say.but try to check each and every apps that you have installed and see if they have sync or update requests and prolly modify them to manual.see also if ICS has a push notification request like "send errors to" or "check updates"
3G ofcourse
Maybe it's the kernel. Currently using Speedmod K2-18-test12. Lost 50% battery during the night. The phone wasnt awake but didnt enter deep sleep either.
Will try Speedmod K2-18-test16 next. If that doesnt solve it I'll try a whole different kernel.
NOTE: The issue is not with the Android Dropbox app, it's with Dropbox on your Mac or PC on the same network as your phone.
I was having a bad battery drain on my phone while connected to my home Wifi - as much as 3-6% per hour while the screen was off. This happened both on the stock ROM as well as CM9 and CM10. I finally figured out the cause - the dropbox program on my regular computer had an option called "enable lan sync" turned on. Apparently this makes your computer constantly send out broadcast traffic across your wifi network to all devices on your network. Some phone modems will see that broadcast traffic and wake up, meaning very little deep sleep, meaning poor battery life. I disabled lan sync on the computer and now the battery life on my phone is insanely better! It drains maybe 1% per hour. Note this doesn't affect all phones, just certain chipsets/modems. The Galaxy Note seems to be one of the ones affected.
I've been monitoring wakelocks with BetterBatteryState for awhile, and always say a wlan_rx_wake under kernel wakelocks. I Googled periodically for a cause and couldn't find anything. Tonight I got lucky and found what I needed to narrow down the issue.
It hasn't completely stopped the wlan_rx_wake wakelocks (I suspect the ones I'm still seeing are for real wifi use like background synching), but it has made it drastically better.

Did you even read the post? The issue is when you have Dropbox installed on a PC (or a Mac) on the same network and the Dropbox program has the "enable LAN sync" option checked. This has nothing to do with an app on your phone.
This worked for me. I was at 3-5 percent drain per hour on my Note and since I turned that setting off on my pc, I still had 100% battery at 1 hour 52 minutes on battery. A definate improvement thanks!

Re-read the OP, that has nothing to do with what we're discussing here. The issue is not with the Android Dropbox app, it's with Dropbox on your Mac or PC on the same network as your phone.

You're missing the point. The dropbox program on your machine is constantly sending out broadcast packets to all IPs on the network. Certain cell phone modems (it doesnt seem to affect all android phones but ours is one of the affected ones) see those and wake up the phone. It doesn't matter if you have the dropbox app on your phone. The PC is waking up the Android OS via the modem.
Found this through the super thread. Nice info. However, I had a hard time finding out how to turn off lan sync. I opened my drop box and couldn't find the options.... Then for the heck of it I right clicked on the tiny icon on the bottom bar of my windows 8 PC. found the cog wheel, preferences> and then the settings opened. And lan sync was indeed checked. I don't know if it will make a difference, but I unchecked it. Thanks OP.

Actually if DropBox app has the Sync setting turned off, then it doesnt matter if the PC is broadcasting or not. It shouldnt affect the device in anyway. If the app is made properly for the device, it wouldnt receive the signal since Sync is disabled. It wouldnt matter if the desktop sync was on or off, if the app sync was off. Cant have a sync if 1 of the 2 devices has it disabled.
So if your still getting battery drain and you can prove it is from this app, then you should contact DropBox and notify them that they have indeed messed up. I can prove my side of this simply. I have never disabled the Desktop App Sync. But I have yet to have any effect from my device.

Cant tell me that after 20 Hours on WiFi with the Desktop App Sync being on that I wouldnt show at least some life from DropBox on my battery usage. I can see usage from the Live Wallpaper, the game I played, Nova and others. But nothing to backup DropBox Desktop App Sync being on. So that tells me that DropBox has either updated their App since this was posted to prevent this issue, like it should do to begin with, or you open DropBox and forget to close it out. Cause I dont see anything to support DropBox using battery when not in use, even with Desktop Sync on.

Works for me too
Hi
I have dropbox 50.2.2 (Android 7.0, galaxy S8) and the phone started telling me yesterday that dropbox was using too much power (3-4%) and would I like to shut it down?. I had two computers with dropbox on my local network (onw linux, one windows 10) and both had lan sync on. I've turned lan sync off and dropbox has gone back to 0.09%/hr.
When connected to my home Wifi my battery drains MUCH faster than when on 4G, 3G, Airplane mode, etc.
I've been noticing it the last two weeks or so, I have an updated Verizon LG 3 Stock + root. I tried factory reset, and reinstalling only a handful of apps (xposed+greenify+amplify and ones I use regularly), still happens. I've noticed "Android OS" and "Android System" take a large increase in battery used when connected to my home wifi vs mobile data. It doesn't seem to be downloading or syncing differently, but of course it could be transparent to me. I've tried looking at the wakelocks, alarms, services etc, but nothing in particular sticks out and I've tried limiting the ones that do in amplify, but the problem persists.
With my wifi turned on and connected, then wifi off (both just sitting in my house.)

EDIT: See my post below for usage stats.
Any ideas as to what might be causing it? I've tried BetterBatteryStats, Amplify, Greenify, OS monitor, none of them show a clear culprit.
I have the same issue with my work Wi-Fi, however at home I get fantastic battery life. For me, when at work even if I rarely use my phone all day, I'm talking less than 30 minutes of screen on time, the battery could be down to 60% after 8 hours of just being idle. I believe this is specific to the wireless network we have setup, as it only happens here and not when at home on my personal Asus router. When looking at the battery stats the phone says it was awake for 4-6 out of those 8 hours, and that Android OS and system are the culprit. Compare this to home, where similar use will yield my phone being at 95%+ after 6-8 hours of just being idle with light use.
This isn't just the G3 though, I've tested a Moto X 2013, Droid Turbo, G2, and I've heard from many other users that they get horrible battery life at work.
Since my phone use at work is very minimal, I used the Xposed module Smart Network, which I have set to turn off Wi-Fi and mobile data after 1 minute of the screen being off, with mobile data enabling every 30 minutes (I only get 1x at work), and Wi-Fi every 60 minutes for 1 minute. What do you have for a wireless router at home?
hmm, could be, but it hasn't always done this when I'm at home and I haven't changed any of my network settings. I have a Linksys E-3000 running Tomato.
P.S. I don't trust those battery usage stats, after a full charge overnight with the screen off and no usage for 1 hour, it was still reporting screen usage as ~45%. I'll update with GSam battery stats and ampily when I get home. I'm going to try a full day wifi on but NOT connected to wifi, then a full day of wifi on and connected at home.

Usage during the day at work (wifi on, but not connected to a network), Android System still seems a little high.
And after an hour and a half connected to my wifi, battery starts to drain. "Android System" and "Android OS" will keep rising as the night goes on.

Do you get a good mobile signal at your house or wherever you are wifi?, just a thought, but your 3G/4G radios do not turn off when connected to wi-fi, it dosnt use mobile data but the radio is still on, if you have a weak signal it will use more battery searching for a better signal, try turning mobile data off while your connected to wi-fi and see if that makes a difference...
Alright, did some testing today. Here are the results.
I fully recharged it and left it alone for 4 hours (except for a little google music), collected the screen shots, then connected to my wifi, and waited 5 more hours. Only touched the phone for maybe 10 minutes either time.
I get good 4G in my house so that's not an issue. "Android System" and "Android OS" are just kicking into high gear why connected to my wifi.
The battery life looks impressive even with the issue, @40 hours, but i was not using the phone at all AND is about HALF of what the non wifi is using.
Wifi on but not connected on the left. ---------------- Wifi connected at home on the right.
The non wifi on the left even has more Wakelocks, but much less battery used.
Screenshots of the services & alarms are here... http://imgur.com/a/wHf1F but they are pretty much identical both times.
Alright, who else has an idea why Android OS and System are using so much?
I'm having the same issue and just as stumped as you. I'm currently running BeanTowns 11c stock ROM and the Skydragon 2.7.3 kernel. Was going to move to the skydragon 12B ROM and see if there was any improvement as there is no evidence of any offending apps causing this.
One change I've made but haven't had time to test the results is I've killed the Verizon Caller ID name and visual voicemail apps. I hear they try to maintain active 4G connections even on Wi-Fi which may cause excessive drain. I suspect this may be reported as part of Android system and not the apps themselves.
Came across this is advanced wifi settings, is yours ON? no idea what it does or if it has anything to do with it.

I keep those options off:
-Allow wifi scanning will kill battery
- Battery savings for WiFi causes notification delays for me. I don't notice significant savings with it enabled on any other device I have.
I can confirm I have fixed my issue by disabling Caller Name ID, Visual Voicemail, and LG Health (I think it was responsible for kernel wake locks).
So far today, I've been off the charger for 8 hours with minimal use. ~6 hours on WiFi and 2 hours on 4G with 15min of screen time....and I'm currently at 93% battery.

I disabled all that verizon crap the day I brought the phone home and rooted, so I cant compare stock to the setup I have now, but I can say I am impressed on the battery life of the phone compared to my previous phones and the screen it has....

Agreed! Battery life is pretty good once you eliminate all the bloat.
Oh, another thing I forgot to mention was I had location disabled all day. One thing to check which definitely contributes to this issue is to make sure that if you need location use "Device sensors only (GPS only)". If you use "High accuracy" or "Battery savings" then a lot of google services go crazy over a wifi network by constantly polling for location. There are aspects of google services that can be disabled through the "Disable Service" app in the play store to help fix this....
My phone has been showing extreme wifi power usage since day one.
It has the same percentage as the screen most of the time. 10-15% drain at most.
It seems to level off and not extreme-drain after a while.
No clue as to why.
And here's the kicker; it's not turned on!
I know location services can be set to enable wifi in the background, this is disabled.
And the high power usage remains even when location is forced to "device only"
The Wifi is set to sleep when screen is off, although I don't see how that would change anything as it's turned off.
It has no correlation with signal strength, as some have suggested on other phones.
Resetting WiFi settings fixed it for a day, until I logged on to a WiFi again.
There's no strange activity when I enable "overlay cpu usage"
So I'm stumped. Restarting it works sometimes, but this isn't Windows XP...
Hello I have the same probleme with my moto z ....Even without using the wifi I use a higher screen
I hope that an update will correct this
mine is turned on and it drains the same as you describe.
I read several blogs and the problem is that the OS is taking a bad reading about the wifi battery consumption, meaning that this is a "bug", not that the wifi is really draining your battery. I made a few test by myself; first, the Wifi is the second place on battery stats, just below screen time, so I decided to charge the phone to 100% and use it as normal with wifi turn-off all day long, using only 4G/LTE signal and the battery was worse than using wifi signals, and surprise, the Wifi was second place again, not even using once on a that day. The second day I charged the phone 100% again and leave it unplugged over the night (12am to 6 am) with all connections on, and the battery drain was only 2%, pretty good in my opinion, and for the first time that day the wifi was the number one on the battery stats, using like 50maH at that time, if you make the math is not even possible, if the baterry is 2500ma and was 2% stand-by meaning that the 50mah consumption were only the wifi??? what about stand by, or sleeping???.
Today, my battery is 40% left and the wifi is number 1 again and STO is second, with 2 hours and 15 minutes and the wifi 10 hours on. As I said, I read several blogs and I am pretty sure is a bug, because I dont see that the wifi is really draining my battery.
The thing is my phone is running hot in my pocket, and no other application is using power according to the list.
BUT, I actually found a solution.
It's the Smart Lock, I had it set to use my location as a "never lock" area.
This setting apparently started the wifi continuously.
I entered Smart lock settings, deleted all entries and boom; WiFi doesn't even make the battery list any more. It's sub 1%.
And my phone is no longer scalding hot in my pocket either.

Ok, you are right, the wi-fi is indeed draining to much battery, but after serveral configurations I found the right one, even you can use the "Smart lock" with out problem at all

That's settings I run most of the time, but for me it disappeared entirely with the smart lock location..
However, now there's a weird ghost drain, the phone will drop 20-25% in 4-5 hours with an absolute minimum of active use.
The phone is room temperature, so nothing appears to use any exorbitant amount of CPU like before.
And there's no obvious power hog in statistics either. :S
There's got to be some kind of bug with the CPU power down mode or something.. Not sure how I'm going to track it down.
Com.android.systemui is the only process in CPU stats.
But it shows 9.0 usage in all three rows.
Is that process using 90% CPU?
@Shadowdancer123 install Wakelock Detector Lite from the Play Store. Then follow the instructions in the Play Store app description on how to use it with a non rooted phone. When you are done running it you should know what the drain is from.

So I finally received my USB type C cable so I could connect to my computer and install wakelock lite.
Found several guilty apps, two games which I'd installed but forgot about, that ran a lot in the background.
But biggest hog was an app called e-control for my broadcom wireless gadget, it had woken the CPU 4000 times in 3 ½ hours.
There's obviously a bug with battery stats, as none of these were visible there.
Or it only counts apps in foreground which is kind of pointless, as I already know my games eat battery...
Now when I leave the phone unplugged at night, after a full charge, expected battery life is 3-4 days in the morning.
Which is still terrible, but realistic.
Turn off location permission on google chrome Settings > Apps > google chrome... change permissions.. that is what fixed it for me.
Went from 20-27% wifi battery drain down to 5%.

did it report at chrome or did it report as WiFi?
May wifi is always on but no WIFI usage in battery..? plenty of bugs. I just bought this last week.

It reported the battery usage as Wi-Fi in both the system battery UI and GSAM Battery monitor.
Hi all, I'm still on the old firmware with July Android security patch update. I still get the false wifi reading after trying all the methods suggested here.
