Hi Guys
I dunno if I am the only one that is suffering this problem as I haven't seen any posts about it but:
I use 2x Battery to save power over night when I am sleeping, and this turns off Wifi/Bluetooth and GSM/HSPA Data, and periodically will turn them back on every 2 hours to allow my phone to get emails and other notifications.
Since the introduction of Android 4.3 to my device, every couple of days I have to switch my device off and back on again because Wifi refuses to turn on. Exactly the same problem existed in 4.2 but instead with bluetooth refusing to turn on, which I might add has been fixed in 4.3.
Has anyone else experienced this?

Personnaly, i rather switch wifi and sync off in the night, coz i only have a look at my phone in the morning.
And i can tell that with last update (JR..Y) with data & wifi off, that the battery isn't draining more than 1% in 6 hours.
4.3 included several battery saving optimisation, have a look in the wifi advanced parameters...
Thanks for your input on battery saving methods but I'm trying to resolve a potential software issue with Wifi

Of course. But take care about the compatibility between your battery saver app, and you android's version... JWR66V ? Y ? JSS ?!
Are you sure they are both compatible ?
Did you try to wipe cache & dalvik, and reinstall your app ?
I think that it's your app that's not "aligned" with OS api's.
You can test Snapdragon Battery guru
I use Llama which is a real great app for controlling your phone and it does occur where it will not turn my wifi back on. With all the optimizations with wifi in 4.3 and battery saving I just decided to leave wifi on all the time. So far it has not caused any real noticeable drain maybe an extra 1-2% total
WiFi not turning on after android 4.3 update
Hey guys,
First time poster, long time reader.
Now I've been doing some hard searching on this issue but I don't think this problem has been completely addressed yet (Apologies if it has).
I updated to Android 4.3 today on my Galaxy S3 (GT-I9300). The update seemed like it went smoothly but after it completed I noticed that the WiFi wasn't turned on. Once I click it looks like it loads and after a few seconds just stops. So I simply cannot get the wifi to turn on!!!
I've tried clearing the app cache, and looked at different forums but has anyone else come across this issue?!
Please help!!!
Thanks in Advance.

/I posted this in another thread but I'm desperate for help at this point.
At one point last week, my Nexus 7 had been running on eight hours from a full charge, screen had only been on for 1:15 and Android OS had kept the device awake for almost five hours, and used 50 minutes of CPU total. My battery was at 71%.
After receiving advice to do a factory reset, I did so on Friday and my battery life improved dramatically over the weekend. Android OS was using a much less percentage and keeping the device awake less. My battery lasted over two days with +4 hours of screen time. But once I commuted to work this morning, my problems started again. Android OS' percentage used and time kept awake shot up and my battery is down to 61% in 22 hours (1:11 of screen time) and Android OS has kept the device awake for over 6 hours.
Is this an operating system problem? Does anyone else commute to work and use Google Now for public transit updates? I have Latitude updating off but otherwise all GPS, etc. is turned on.
I am absolutely baffled and would love some help. Thanks in advance.

That seems to be the culprit. Try turning ALL options in the Location services off (Google's location service, GPS satellites, Location & Google search) and turn them only on when you need them.
This did the trick for me.
Otherwise use the tools CPU Spy and BetterBatteryStats (both available in the Google Play store) to get a better idea what exactly is causing the battery drain on your device.

Thanks for the response. That's probably my last resort. I mean, I bought this device because of features on Jelly Bean such as Google Now, which relies heavily on location services, and I have to turn all of them off? That disappoints me.
It's interesting to me that I had all of these services on at home over the weekend, yet it did not have this effect on my battery. Only because my device leaves the house should it freak out. That's a serious flaw.

This may or may not help, but I too was having battery problems but narrowed it down to being only when I was away from any Wi-Fi connection whether I was connected or not. I think there is a bug whereby if the tablet cannot establish your location from nearby Wi-Fi access points, rather than giving up it just keeps on trying to the detriment of your battery. I solved this issue by using an app called Automateit to instruct my Wi-Fi to turn off when the screen is off (as it would be the majority of the time while travelling). These kinds of apps allow all kinds of qualifiers, for example my Wi-Fi doesn't turn off if Spotify is in focus as I am streaming music using Wi-Fi. Give this a go and see if it helps.

Thanks. When I'm at work it stays connected to the same WiFi access point as far as I know.
Here's an update to the situation: I looked at my data usage over the last few days. Over the weekend, Android OS used virtually no data. Since then, it has used about 50 MB of data in the background. I work at a university so maybe it's trying to connect with other access points on campus even when I'm in my office. Any ideas? Thanks.
Edit: At work, the down arrow on my WiFi signal is constantly on, like it's always doing something. At home, not.
Hi all. I have noticed a problem since updating my samsung gala y s4 i9505 to jellybean 4.3

Try making sure your WiFi is off by going to Settings->Wifi->Menu Button->Advanced-> Disable Always allow Scanning(4.3 only)

This was already turned off me, and I also have been experiencing battery drain after updating. Google services and screen..It's annoying
Check to see for Wakelocks you may have some apps keeping your phone awake.
I recommend either betterbattery stats or wake lock detector. Both available on the market. Let that run over the course of a day then check to see if you have any high number of wakelocks caused by any apps.
Also see whether you have location reporting on or off in the Google settings app. Location can sometimes hammer with wakelocks.
It's probably one of the apps you have installed, I never have any battery problems with 4.3

Doesn't the wake lock stop the phone from going into Deep Sleep? Mine seem to sleep just fine but ever since I upgraded to 4.3 it drains almost 40% over night. With Wifi and BT turned off it's only about 3%. the 'always allow scanning' option is turned off.
Is the Mobile Data on? Do u have a Exchange account added? Because I see the issue is because of the Mobile data always trying to download or upload something. I disabled the exchange account and it started working fine. But that just a workaround.

Thanks.....I do have two Exchange accounts and without Wifi and mobile data things are much better. I think I'll delete and re-create the accounts on the phone.
I've noticed bigger battery consumption too, idle and with screen on. I even did a factory reset but to no avail. I definitely used to get much longer screen-on time than before, such a shame.
Check your battery! My battery life started to decrease not long after moving to 4.3, thought it was the ROM but turns out I had one of those faulty batteries.

Definitely WiFi for me. On Mobile data it drains 2% in 8 hrs and on with WiFi on it drains about 35% or so.

Hi.
To make sure WIFI is not using up yr battery, check google play store settings and uncheck updates through wifi. and u might also want to uncheck software updates through wifi in settings/about device/software updates.
Next is open Google Settings app, go to Android Device manager and uncheck "Remotely Locate This Device".
Another thing to point out is to uncheck "notification reminder" in settings/accessibility/notification reminder.
This was the big culprit for me for the 100% screen awake on my device...
Cheers..

Thanks for the suggestion. I've done all of that but my Wifi battery drain remains. I even disabled active sync altogether but still screwed. Either I disable Wifi or the battery drains overnight.

Have u tried re-installing yr firmware again?
What custom roms and kernels are u using?
Since the day I installed 4.3 knox-free version, i have no WIFI drain issues apart from the '100% screen awake'.
I'm using MJ5, all google-related connectitvity turned off, I'm having 2 and half days of battery life.
Deep sleep is between 92%-96% all the time.

I did reinstall the firmware a few times actuallybut in the end I fixed it with a reset. I reset my phone (from the settings) then gone into recovery and formatted cache and data from there as well and the drain was gone. Must have been something in the old settings coming across from 4.2.2. Pain in the A*** but at least it worked. Lase night I upgraded to MK8 (DBT so MK8 radio as well) without a reset and there is no drain.

So recently I updated to 5.0.1 but I realized that I got big battery drain issue. I looked into the Option --> Battery and noticed that my phone has always been awake. Also, even if I turned off Location, I can still see GoogleLocationService running under Running Apps/Google Services.
And now the phone also tries to identify the caller ID. I think this was a Google Now feature, where do I turn off this? Also why is my Backup account greyed out?
Thanks.
Turn off WiFi and Mobile Data when screen off. It's save battery for almost 2x. This is bug on Lollipop.

So you cannot receive messages from IM apps and you cannot sync any of your accounts, basically negating the purpose of a "smart"phone. You, sir, are a genius.
And please stop blaming lollipop for every bug you come across. I'm getting the same battery life I got on KK.
I'm at a loss here and i hope somebody can help me out here.
I've had my Note 4 for a while now, working great, but after a week or two after flashing Simpl-rom (latest)(Android 5.0.1) it started to drain battery while the screen was off.
I tried to debug this issue and found that WLAN_WAKE is preventing the device from sleeping.
Of course i did search for solutions but none of that worked, disabled all the background scanning and stuff in advanced wifi settings.
I tried to freeze all my regularly used apps planning to unfreeze them one by one to see when the issue started to show up, odd thing is, the issue persists even if i freeze all my daily-use apps.
I also noticed no networks in range show up in my Wi-Fi list, only the ones that i saved in the past (of course most showing out of range).
Using a 3rd party Wi-Fi manager works fine, it detects all the networks in range.
Disabling Wi-Fi allows the phone to go back to sleep again. However, when enabled again after that no more sleeping occurs.
The only "solution" to this is a full reboot. This solves the wakelock/batterydrain issue temporarily but not the Wi-Fi networks not showing up.
It can take 30 minutes before the issue shows up again or it can take half a day.
I also tried to detect if any apps were using background data, none that i could detect.
Even stranger, i have the exact same issue with my Galaxy S5 running Omega-rom (latest). (Android 5.0.1)
The drain on the battery isn't huge (10-15% per night), but it's there and unnecessary (i know it can do with 2-3% per night if the bug doesn't occur), obviously something is going wrong and i wish to find out what and resolve it.
Anyone experienced similar problems or knows how i can proceed to debug this issue?
I say issue because i feel these problems are related, they could be separate problems though..
when turning my wifi off it seems it goes into some weird loop of turning on and off constantly by itself, it doesn't seem to be trying to connect just flipping the wifi switch on and off none stop.
noticed it because i had a huge battery daring overnight and while trying to fix it i saw the switch going off and on all the time.
when turning it back on it seems to connect normally .
did a network setting rest but it did nothing ...
I'm guessing a factory rest will fix the problem but I'm hoping to avoid such a overkill solution :crying:
does anyone else had this problem and can help me fix it?
thanx!

original samsung rom.
just happened (i have the device for a a while everything was fine) its the android system that drains the battery in the battery status.
when i leave the wifi on it stops and works fine ...
Have you turned off ''Keep Wifi During Sleep''? I know this can drain battery.
It's not so easy to troubleshoot on an orginal none rooted phone.
You can try clearing dalvik and cache.
Turn it off and then on holding power and vol down button, then clear cach/dalvik and restart.
Try uninstall update beaming service for samsung then restart
If still persistent try uninstall update microsoft onedrive and skype then restart, just in case
I found it after factory reset (forgot internal data backup :crying and update all apps, this problem occuring after the last 3 updates (beaming, onedrive, & skype) which more suspect beaming service update make that problem
Your not alone
You're not the only one who suffer from this exact problem, on Friday or Saturday the same problem started occurring with my phone too, WiFi turns on and off in a loop and huge battery drain!
I saw an increase of 6% of battery drain per hour, so I ended up on 9% total drain every hour. :crying:
I have original Samsung Rom and phone worked prefect until now, no settings or apps installed before this happened either.
What rom version are you guys on?
I'm having the same issue. However, I'm on PhoenixX Rom. Major battery killer and has only just started happening within the past few days.
Since my phone has been unplugged, 3 hours ago, looking at BetterBatteryStats, It is showing com.google.android.gms as having quite a LOT of wakeups. 40 per hour (everything else is about 2). Don't know if this is normal as I don't remember it before the Wifi issue.
Looking into what the wake ups are caused from, Location and heartbeat were the major culprits. So i have turned of WIFI scanning when not on and also the body sensors for Google Play. We shall see.

its not a fix at all . it dosnt scan for wifi , just turning it on and off non stop.
like pressing the light switch agin and agin
I had this after installing "GoodLock" software from Samsung! Uninstalled and everything is ok
same here, just noticed I wasnt on Wifi and the switch is just flicking on and off by itself. Standard S7 with all the updates installed
Been struggling with the same for some days (4 - 5) I haven't been able to get exactly whats triggering this. I'm on stock rom with root. I've reinstalled firmware clean again and re downloaded my apps but it is still happening randomly. Some times after a few attempts to switch wifi on (even when it is toggling by itself) it manages to keep on. Sometimes restarting makes it work again. One thing I'm almost certain its that this usually happens after I turn wifi OFF and then try to turn it back on.
It's been crazy and the phone starts to overheat after a while off this on-off loop.
Any ideas?
its very wierd it started to all of us in the past few days-weeks . seems like samsung has a bug they need to hurry up and fix.
AT&T just pushed out the October Security update for the S7 family, I'm guessing something that came along with it is creating the problem.
mine did a software update last week and I've been away in airplane mode so it could have started then. I've just disabled scanning and that seems to have got round the issue and I'm now connected to WifI
I'm not sure whether it is a Samsung Issue or a Third party one... It is true that something recently affected all of us, but as far as I know, it could be a third party app that wasn't well developed for our phone.
I've noticed the same problem on my phone and it's also only started up in the last few days. On stock Sammy rom, unrooted. Will be monitoring this thread to see if the experts here can narrow down the culprit.
I had the same issue and I was able to stop the toggle by turning off the wifi scanning in Location - Improve Accuracy - WiFi scanning. It's a fix for now. I think it may be an app that may have been updates that is persistently looking for location updates.
