When wi fi turned on the note keeps scanning. Even when i have connected to a wi fi network - it still scans for the other networks - which I do not want as obviously running battery time down. Also I do not want to delete the other networks because I am likely to use them again when in range.
are you using any battery saver software like Green Power or etc? Try uninstall them first...
I asked the same questions ages ago. The story is, it only keeps scanning while you are in that screen. Reason being even though you are already connected to a wifi, it might not be the one you want so it will keep searching what else is available every 3 secs.
It isn't a problem and it definitely doesn't scan any other place in android otherwise your battery won't be lasting as long as it is
Thanks guys for your quick reply. I an not using other software and I now feel reassured that when I am not on the wi fi screen the note is not scaning.
On a side note (no pun intended), I travel a lot for work. I ended up with about 75 saved wifi networks. I found it took longer and longer to lock into my home network when returning. After deleting 75% of the saved networks, the sync time improved?
Anyone else notice this?

Hi
Another observation is 'When I am connected to a WiFi network of excellent strength, I see down-up link arrow continuously blinking below the WiFi icon in status bar'.
My youtube videos are paused after every 5-6 seconds just because WiFi is still scanning for open networks which is not a user friendly.
Otherwise there is no merit of buying costly and fast android smartphones.
Regards,
I got the same issue and gave up. It is there with different roms and kernels. Battery drain is acceptable though. Suppose it is hardware related.

/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,
First android device and curious if anyone else is having an issue with WEP WiFi security when opening YouTube,Google play,etc. I sometimes get the "network not available" screen when I try to open any of these apps or try to browse. When I hit the refresh button it loads the page I am trying to view. Usually it takes one click,but other times it takes 3 or 4 for the page to load and stop giving me the "no network available". I tried disabling sync in the background with Google currents but it doesn't fix the problem. I've read other threads that there is lots of WiFi problems such as the range and connecting to certain networks. I can be as close as 10ft away from router and it will occasionally happen. Now I can live with it, but rather fine a solution as pressing the refresh button fixes the problem. I have yet to discover a solution whether this is a bug or hardware related. Any input or solution would be appreciated.
Running jelly bean 4.2.1 version on a 16GB. Should state that other devices over the same WiFi connection don't have this problem.
Thanks in advance!
In the Wifi settings do you have it set to turn off while sleeping or not plugged in?
I have that checked to save battery and sometimes it takes a few secs to come back on and sometimes have to reload the page as well.
reply
Never knew about this setting ,but I have selected to always be on since I usually shut it down at night. I can be browsing Google play for example and say I want to buy an app and when I click on it I get the no network connection page. Been reading and saw a poll here about people having WiFi dropouts. Not sure if that is the case for me. I will look into it next time it happens if the network still On ( or at least it shows its connected). Thanks for the input
In the morning before I go to work I usually disable WiFi as I don't use it at work and would like to save a little battery. However, I've noticed that throughout the day, I'll check a notification and see that WiFi has turned on without me turning it on myself. I can't see any pattern or correlation that would match up with this. Does anyone know what would cause this? I factory reset last night (due to an unrelated issue) and it's still occurring. I only have a couple of extra apps installed, Falcon Pro and reddit sync.
i think power saving mode sometimes enables wifi when its available... not sure how often this happens or if thats even the issue you're having but check the power save mode settings... 3g and 4g use more power than wifi

I don't have the power saving settings enabled, and I don't see any setting that resembles that kind of behaviour.
So at some point while I was driving home from work WiFi enabled itself again (I didn't even touch the phone). I'm wondering if it may be S Beam causing it? I haven't actually used it but it's the only thing I can think of that would need to actually turn WiFi on. I may try turning it off tomorrow morning when I turn WiFi off and see if that stops WiFi from randomly enabling.
Galaxy S4 Wifi auto enable
Is there a resolution for this? I heard that on the S3 it would pay attention to what cell towers you are using and if it recognizes you are in an area where you have used wifi before it will enable and connect. This seems to be the symptom that I am seeing and it's bad for me. It keeps trying to connect to my work network because occationally I log on so I can access materials. but when I want to listen to Slacker Radio I can't because it's blocked. This is a cronic problem for my phone and I'm not able to find out how to disable it.
if you have got any battery saving apps delete them

Hi
I'm currently having a problem with my S4 that is driving me mad.
Ever since I got the phone I've had a bit of a problem with the WiFi connection. I've flashed a few kernels and some seems to help the problem more than others but it's still there.
What happens is the phone connects to WiFi no problems. Then maybe after a few minutes of use the phone won't give me any data. If I search a Web page it just hangs and then says unable to display web page. I then have to knock the WiFi off and back and and it cures the problem temporarily.
Sometimes the WiFi connection can be fine and last a few hours without hanging. Other times it can last a few minutes. The WiFi icon always remains on the screen and the arrows act as if data is getting processed but nothing ever happens. The odd time it will also kick itself off the WiFi and reconnect.
It's driving me mad having to constantly knock it on and off. I'm missing WhatsApp messages for hours because of it also.
Is it a common problem? If not the phone
is still under warranty so I will have to send it back but then that's me phone less for god knows how long
Any help would be great.

if you are rooted, flash this http://www.adrive.com/public/8DJWtV/WifiFix.zip
its a fix that sorted out my wifi problems
I think you should revert back to the latest stock and reset your modem. There might be some fancy settings in your modem software that need to be turned off. I read that somewhere but can't remember which ones. Just search on here.:cyclops:
Hi guys, sorry I've just seen the replies and thank you for taking the time
I shall have a blast at both your solutions and report back.
Thank you again
Well I tried the WiFi fix but that hasn't cured my problem. Today I will flash to stock rom and then re-root and see if that makes a difference. If not its off for repair under warranty and the old Nokia 8210 will be coming out of retirement for a few days lol

May be a fix?
1) type *#0011#
2) press menu button and select wifi
3) turn off power saving mode
4) restart
Alternative
1) download terminal emulator
2) type ping google.com

Hi jehbrian.
I've never heard of this fix but I'm willing to give it a go (whats the worst that can happen lol).
Done the above and indeed you get to a point where Wifi power saving mode is on. I've knocked it off and will see how I get on in the next couple of days. It does make sense that the power saving mode could be killing the Wifi every now and again.
Thanks for the tip and have a pleasant day :fingers-crossed:
I had tried that one. It spends about 10% more battery.

Does it?
Surely there must be something else that can compensate for this loss if it means the Wifi actually works. GPS? Bluetooth? Screen brightness?
My phone is on my dock so can't verify the loss of battery.

I've never noticed the battery drain... besides, S4's battery life is bad anyway.

No matter what Wi-Fi, I'm in, my phone always displays 3G next to the mobile signal for one second every few seconds... Is this just a display bug or is something wrong with my device?
I think it's not an issue. It might be due to some of your apps. I had seen some apps using mobile data for some small chunk of info even if wifi is on.

Didn't work for me... I also get quite the battery drain when I'm on WiFi and have mobile data enabled

After half of the day, you can see way less battery drain - I turned off data then
From one of the other threads, there's a setting in developer option that allows mobile data to be enabled all the time, even when on wifi. Maybe you enabled it by accident?

you can install greenify and see if it works...
This is a known issue, ZTE will be fixing it on the Global version.
