same here set it up and not using it but it is sucking up battery .. this is a big problem. this phone isnot ready yet for my daily driver.. think i am going back to my sgs

i was getting 10% usage in about 2 hours.. i normaly get 3-5 % overnight with my sgs

anyway i have read a few threads and froze (makes them unruneable /using titanium backup .

software update

wifi sharing

and wifi sharing manager

i can always re-enable them if i want to tether

i will keep you informed on how this effects battery

i also used autostarts to disable accuweather which kept starting up.. i dont use any weather widgets other that beautiful weather which has its own
[Galaxy S II General] alloneword:
Sitting on 7% battery now. Been going all day, 10.5hrs, and NO Wifi sharing in the battery usage. Didn't turn Wifi tethering on at all today.
[Galaxy S II General] Leggenda:
This morning it happened again ... But unlike yesterday, instead of killing the process I tried to enable and disable wifi hotspot and the process has finished eating cpu and battery!
[Galaxy S II General] tomelsmith:
I have the same problem, both Wi-fi sharing and Wi-fi sharing manager appear in my 'running services' and are consuming a lot of battery power.

I have not enabled wifi tethering, I've tried enabling and disabling, but this has not fixed the problem. I have used Kies air before, but have made sure that this is not running too.

I can force stop wi-fi sharing and wi-fi sharing manager, but they will re-appear as soon as you re-enable wi-fi.

Any idea what this is? or how to stop it?
[Galaxy S II General] Leggenda:
In this moment it's started again... very annoying...
[Galaxy S II General] opencube:
How can you see that screen with the info on what uses x amount of power?
[Galaxy S II General] tomelsmith:
Settings > About Phone > Battery Usage

or

[Galaxy S II General] rdy2go:
Factory reset and don't touch it again.

Helped in my case
[Galaxy S II General] vimto25:
Why not root and then freeze it
[Galaxy S II General] simonk83:
That's what I've done this morning. Not sure what else it'll affect though (Kies Air I expect, but I can live without that).
[Galaxy S II General] vro25:
I'm having the same problem. I don't think "Wifi Sharing" itself is the problem... I think it's another app that's using it. I noticed it come up today after I added some new accounts to GMail and installed Kik. Not sure which one was the trigger, but it wasn't in my battery usage prior to that. My phone is currently syncing so it might be related to the new accounts.

Another thing, once it's on, it stays on. Stopping it doesn't seem to have any effect as it will come back on. They only way for me to stop that service is to reboot my phone - it works every time.

It's annoying that it keeps coming back every couple of days...
[Galaxy S II General] ong.andrew:
I seem to have success turning off WiFi and stopping (Settings -> Applications -> Running Services) WiFi sharing and WiFi sharing manager. Just unchecking the Portable WiFi Hotspot doesn't kill those services and they continue to sit in the background sucking up power.
[Galaxy S II General] AXIS of Reality:
I have never used WiFi Sharing, and yet in my battery usage it lists it as using 12%! I checked in settings and it's definitely turned off.
[Galaxy S II General] llBlackenedll:
Mine does this too, seems to be an SGS2 bug. If I freeze it then tethering doesn't work properly (obviously), but I don't need to tether most of the time. I'm going to freeze this and un-freeze it when I need to tether until the bug is fixed. One thing that's odd is that even though the process is started, I'm still connected to Wifi as normal and I'm not actually sharing my connection. It's as if the process gets into some infinite loop. It also keeps my phone at 1.2ghz when it gets into this state.

Can someone confirm something for me? I froze "Wi-fi sharing" then defrosted it, and now tethering isn't working properly (although I don't know if it was before). Can someone please check if this happens to them? If not, it must just be that I can't tether where I am anyway.

Just so that everyone knows, freezing wifi sharing and the wifi sharing manager does not have any impact on kies air. I'm assuming it also doesn't effect AllShare too, though I haven't tested that yet. It only seems to have an impact on tethering.

EDIT: OK so I just tried tethering somewhere else after defrosting, and it seemed to work just fine (albeit incredibly slowly as I only have 2g reception right now). This is the interesting thing, though - I tried tethering with it Wi-fi sharing frozen, and it still worked. I checked the running processes and Wi-fi sharing definitely wasn't running.

This could mean that the wi-fi sharing process is unrelated to tethering, or at least is not a requirement of it. My original thought was that wi-fi sharing is the process allowing you to move between routers seamlessly, but I'm guessing it's not and it is just something related to tethering, I just can't determine what..
[Galaxy S II General] llBlackenedll:
Briggs over on samsunggalaxysforums . com/showthread.php/4800-Galaxy-S-II-bug-list?p=34624&viewfull=1#post34624 says that he's frozen wifi sharing, wifi sharing manager and wifi 1.0. He says he thinks it's to do with wifi direct or something.

Does the latest firmware fix this drain?

Sorry for the odd link, I'm a new member and can't post links normally.
[Galaxy S II General] Leggenda:
Absolutely Not... :(
[Galaxy S II General] Ussy:
I'm getting the same thing Wi-fi sharing usage is constantly showing even though I'm not using it. I think it may be related to google maps somehow because I also have that at 12% usage even though I haven't used it at all.
[Galaxy S II General] SweCrown:
After installing latest firmware this problem started for me as well (was fine before). One thing I've noticed is that Google Maps shows up as a battery hog - even though I did'nt start the service even once.

Is perhaps Google Maps causing this, and somehow trigger the wifi-sharing?

Comming from Optimus 2x I was so happy with the decent battery life of the SG2, really hope this issue gets solved quickly.
[Galaxy S II General] BoogWeed:
Wifi sharing was on 10% usage after 6 hours today even though I had wifi switched OFF the entire time... :confused:
[Galaxy S II General] SweCrown:
Hi guys,

For me the problem has disapeared. What I did was going to android market place, search for google maps - there I was given to options: open and uninstall update.

I uninstalled update, and since then Google Maps is no longer running in background and Wifi Sharing hasn't showed up either. Perhaps maps acctually is triggering the wifi sharing somehow?

Worth a try anyways.
[Galaxy S II General] dirran:
Edit: i uninstalled the google maps update and thought it might be fixed but after a couple reboots and toggles of wifi to 3G it happened again.
[Galaxy S II General] SweCrown:
:(

Wifi sharing hasn't showed up for me yet after uninstalling maps update.

Don't do any connections via Kies either. You?
[Galaxy S II General] El Salvador:
Same thing happened to me. I removed the update, did a reboot and didn't turn on Wifi at all, only 3G, and the Maps process still shows up in the battery usage menu. Did you join Latitude?
[Galaxy S II General] ianjd:
Given the possible link with Google Maps, has anyone tried unticking the "Use wireless networks" in the Location prefs? I'll give it a crack now, see what happens.
[Galaxy S II General] dan13l:
I posted this in the Android OS battery consumption thread, but it may be of interest here too:

I was playing with Autostarts, and noticed that under Wifi State Changed, there's an entry for Wi-Fi Sharing Manager. If my understanding is correct, that means Wi-Fi Sharing Manager is launched every time you toggle wifi on or off, which could explain why it's popping up and draining battery for people.
[Galaxy S II General] El Salvador:
Yep that seems to do the trick for me. I ticked GPS on instead. Now Maps doesn't show up in the list anymore after I closed it.
[Galaxy S II General] falconeight:
I rooted removed or froze all of samsungs bloatware except social hub. I froze wifi sharing and it has more than doubled battery life in my phone.
[Galaxy S II General] Duffman19:
I've tried turning off wi-fi and then turning it back on. I can confirm I see this behaviour
[Galaxy S II General] vro25:
Definitely Maps Related

My phone was fine most of the day yesterday. After work I was on my way home and started Google Maps to check out the traffic situation. GPS was OFF so it asked me to turn it on - which I did. I got the info and then I exited Maps.

A few hours later I noticed that my battery life was going down fast. I check battery use and sure enough WiFi Sharing was in there. When I clicked on the usage graph my phone became constantly "Awake" from the time GPS was turned on.

On a hunch I went to my power widget and disabled GPS - that's all I did. Checked the phone an hour later and the WiFi Sharing CPU time had not increased and my phone had stopped being "Awake" since I turned off GPS.

So the question is, wtf does WiFi Sharing have to do with GPS?
[Galaxy S II General] vro25:
I just tested Maps and GPS but I didn't get the same results as above. When I exited the Maps app the GPS turned off successfully. The only difference this time was that I didn't get the "Turn on GPS for better reception" message so I turned GPS on from the power widget... This message normally comes up - but it didn't this time.
[Galaxy S II General] El Salvador:
How long was your display turned on?
[Galaxy S II General] hazart:
This problem has been bothering me, too. Never enabled Wi-Fi sharing and never used it but still, it consumes 10% of the battery. I do quite often use Wi-Fi though.

Maybe the 10% battery usage associated with Wi-Fi sharing is owing to the actual Wi-Fi usage such as browsing the Internet, checking emails, etc.?
[Galaxy S II General] Ussy:
I don't think so. I used to have wi-fi sharing on my power usage list but not anymore, even when using wi-fi for over 20 hours. I believe the wi-fi sharing usage comes up when you enable 'Use wireless networks' in 'Location and security'.

After a fresh flash of KE2, the only setting I changed was to not allow Google to collect anonymous data and voila! Wi-fi sharing no longer appears on my usage.
[Galaxy S II General] chukkie:
exactly what i did and also froze wifi-sharing, hubs and kies to be extra sure and I'm getting double the battery life..
[Galaxy S II General] hazart:
Thanks and I've tried. After restarting the phone, there was no Wi-Fi sharing or Wi-Fi sharing manager in Running services. I disabled 'Use wireless networks' in 'Location and security' and turned on Wi-Fi. Both Wi-Fi sharing and Wi-Fi sharing manager then appeared in Running services. And then, as we all know, turning off Wi-Fi doesn't stop Wi-Fi sharing or Wi-Fi sharing manager. I need several hours to tell whether Wi-Fi sharing is still eating up the battery.

I couldn't remember whether I had allowed Google to collect anonymous data during the initial setup. Can I view or change that setting now?
[Galaxy S II General] Ussy:
It appears on the running services for me too but not on the battery usage stats, but when I leave home I just stop the running processes as I know I won't be using wi-fi for a while. When I eventually decide to root, I'll disable them for good.

I'm not sure if the anonymous data setting during set-up is the same as the one in 'Location and security'. I have a feeling it isn't but I haven't really tested it. See how it goes for you for now.
[Galaxy S II General] aussiebum:
Freezing Wifi sharing and Wifi sharing manager with Titanium Backup seems to do the trick - battery usage of "Wifi sharing" is steadily dropping from 12% -> 8% in the stats... I expect it to drop off completely next couple of hours.

I reckon both processes have something to do with Wifi Direct functionality.

The next thing I'll probably freeze is Software Updates as I don't even have a Samsung ID anyways.
[Galaxy S II General] hazart:
Sadly, it didn't work. With 'Use wireless networks' in 'Location and security' disabled and phone restarted, I charged the phone to 100% in the afternoon and it's now at 80% - I used the Wi-Fi twice for Internet browsing. 'Wi-Fi sharing' is now in the battery-eater list with 8% of the power consumption... I guess I have to make sure 'Wi-Fi sharing' doesn't appear in the Running services list manually.
[Galaxy S II General] RMXO:
If you have Kies Air installed, try un-installing the latest update. It worked for me. I don't have Wifi Sharing & Wifi Manager as a running service anymore.
[Galaxy S II General] zoomzoom83:
My Desire always had a problem with Maps eating battery when WiFi location gathering was on too.

I think Android randomly wakes up and samples WiFi SSID's and GPS Position and sends it off to help make location data more accurate - at the expense of battery life.

Turning this off always made a big difference to battery life on my Desire as well.
[Galaxy S II General] jenskristian:
Did anyone find a permanent solution to this? Is the only way to freeze with Titanium Backup?
[Galaxy S II General] ianjd:
That's the only way I found to work reliably, after a few days of experimenting fruitlessly with turning of wireless location prefs.
[Galaxy S II General] dhruvmalik:
So let me get this correct, you cannot use Kies Air and Tethering over WiFi?
[Galaxy S II General] jenskristian:
I did the same a couple of hours ago. The battery graph

clearly

indicate that it helped. I would however love to find an alternative solution because I sort of need wireless location for my minimalistic text weather widget.
[Galaxy S II General] Therollingstone:
Wifi sharing usually drains battery more than normal usage wifi while surfing on internet or downloading , its not problem , i guess.
[Galaxy S II General] mwilson1987:
This issue is doing my head in. Ever since I got the latest firmware update, wifi sharing has been showing up in my running services, and is using a lot of battery. If I stop it in Running Services, it just starts right back up again!

If I go into battery usage, and force stop it, it seems to work for a while, but eventually it will come back on. Also, this means that wifi sharing has to have been on and showing up in battery usage as one of the things that is draining the battery before I can try to force stop it!

I don't want to root my phone as I want to keep the warranty, and have tried everything else that has been suggested in this thread. Anyone have any other ideas at all?!
[Galaxy S II General] Uvaavu:
It's it just a case of uninstalling Kies Air?

I know I didn't install that after my last flash and have not had this issue since.
[Galaxy S II General] mwilson1987:
Sorry this might be a stupid question but how do you uninstall Kies Air? When I go to it in settings > applications there is no option to remove it. Also, if you remove it is is possible to reinstall it should you need it in the future? Thanks
[Galaxy S II General] siksik6:
Mine comes back if I have Wi-Fi on, but it doesn't seem to chew through the battery unless I've started Kies Air... so just kill the service after you've used Kies Air...
[Galaxy S II General] Pfeffernuss:
Flashed a fresh Rom (Villain) yesterday, didn't disable anything but the only thing I setup was the Google account. So GMail was working in the background. Only additional app I installed was Whatsapp.

Without Wifi I had a drain of 1% in 6 hours. Seriously. A couple of Whatsapp messages had arrived and some mail, both I didn't check ofcourse until I turned on the screen for the first time after six hours. Amazed me as well.

With Wifi on (just tested this today) the drain was 2% after a bit over 5 hours. Can post screenies if that's necessary.

Wifi set to "off when screen is off", furthermore as said nothing changed... Wifi sharing running in the background. Very odd. Will setup (push and pop) mail accounts and see if that changes anything.

Now I really don't know what causes the drain in the first place. Android OS has taken 20 minutes after 5.5 hours, also quite doable IMHO.
[Galaxy S II General] Pyrone89:
Why does it seem that custom rom hobbyist (with all respect) are able to produce better software for devices than their own manufacturers.

It is a disgrace
[Galaxy S II General] mindracer:
I'm having the same problem as of today, its eating my battery :(
[Galaxy S II General] pulser_g2:
I dunno... I have less resources available to me. I'm one person, albeit with about ten or fifteen guys to call on for help, yet samsung doesn't seem to have fixed this...

Some people report issues with battery which we're trying to get to the bottom of, but they seem isolated so far.

But intermittent issues are the hardest to find, so that may be why samsung hadn't fixed or spotted the issue
[Galaxy S II General] mindracer:
I decided to factory reset, and I flashed CF-ROOT from http://xdaforums.com/showthread.php?t=1103399 with CF-Root-SGS2_XW_XEU_KE7-v3.5-CWM3.zip

I've been configuring my phone carefully, especially in the Wi-Fi Settings, and I'm happy to report that Wi-Fi Sharing is not there and not eating battery life. I'm gonna pay attention to what applications I install and keep checking if it re-appears (and possibly figure out what caused it to appear).

Only issue i have so far is my Battery Usage screen looks funny

Correction: Wi-Fi Settings does not appear in Battery Usage, but appears in running services:

Wi-Fi Sharing 1 process + 1 service 3.2MB

Wi-Fi Sharing Manager 1 process + 1 services 1.5mb
[Galaxy S II General] iamthecosmos:
I too have had this problem. Please see another thread I just posted in regarding AP Mobile being a cpu hog: http://xdaforums.com/showthread.php?t=1098206

Is there a chance this app/widget could be activating Wifi Sharing? :O
[Galaxy S II General] AmesCell:
I've had AP Mobile frozen since day 1 and Wifi sharing still got kicked on. I'm doing great with wifi on 100% of the time, but with Wifi sharing frozen.
[Galaxy S II General] mwilson1987:
when you say frozen, is this something that can only be done if the phone is rooted?
[Galaxy S II General] mindracer:
Yes you have to root your phone and install Titanium backup if you want to "freeze" apps/services
[Galaxy S II General] victorinoxs:
I have both wifi sharing & wifi sharing manager frozen and my wireless wifi tethering still works like a charm. Not sure what those services are for....:confused:
[Galaxy S II General] rdy2go:
OS Monitor proves your observations - terrible battery drain from various samsung apps - wifi sharing, Days, AP News, AccuWather WTF!

I don't use them at all!

Killing them manually helps for 1-2 hours and they raise their ugly heads again and again.

Afraid too root because of infamous "counter" that would void my warranty...
[Galaxy S II General] CdTDroiD:
I dont know if this has been posted, i havnt read the whole thread. but i just put .bak on to the end of FTM.apk, and FTS.apk to disable them and its worked mint... of course you have to have root but so far has saved me alot of battery
[Galaxy S II General] mindracer:
I'm glad to report that after a few days with the CF-ROOT kernel posted in the dev forum, Wi-Fi sharing has never shown up, and ive been installing apps etc.. Ive avoided using any of samsung's apps though, and ive avoided upgrading google maps (someone mentioned earlier in this thread t hey suspected google maps..)

:)
[Galaxy S II General] rdy2go:
Google Maps 5.5 always come back even when not launched!!! Remove updates and it's fine again.

Software quality from Google lowers and lowers... (GB 2.3.3 is buggy, maps are buggy...)
[Galaxy S II General] Unamrakerag:
Anyone has any solutions to this problem, without rooting the phone. I also dont want to root my phone, cauz of the warranty issue.

Without rooting is there a way to stop the wifi sharing popping up again and again.
[Galaxy S II General] prodygee:
Root it. Get titanium backup or bloat freezer and freeze wifi sharing. Done!

Sent from my Samsung Galaxy SII with XDA Premium
[Galaxy S II General] Leggenda:
Not solved with KF1...
[Galaxy S II General] notabenem:
Actually, I do not see this bug any more with KF1. WIFI Sharing is still running after I disable the WIFI, but it's not showing up in the battery chart.

Update: I wasn't right above. It still applies (happened several times in the past week). Still not sure, what's the trigger for this.
[Galaxy S II General] carlhunt3r:
I am experiencing the exact same issue, except my wi-fi sharing was at 25%!!! Battery had gone from 100% to around 65% in 2hrs 15mins. I've attached a screen shot of the battery usage screen
[Galaxy S II General] biffsmash:
This is a bit strange. I have Wi-Fi Sharing on 10% although I havent had it all day, except the last hour I left my Wi-Fi connected running while the phone was asleep.

I have never touched or configured wifi sharing, so could it be reporting ordinary wifi as wifi sharing?
[Galaxy S II General] nicpol7:
for me this wi fi sharing drain starts randomly...but at least once in each battery charge circle..and usual social hub drains battery together..its like a drain pair

a game can start this(even angry birds) or even one email notification!!!!

a reboot always solves this problem until the next time..

this is the only negative i can say about galaxy s2 but its something much worse than common bugs..

if i dont see my battery stats and reboot, this thing can drain the battery in 8 to 10 hours..

samsung must fix this immediately...
[Galaxy S II General] Leggenda:
Yes, actually ... but the bug still remained in KF1...
[Galaxy S II General] sandeep10:
I am also having this same problem: wi-fi sharing is eating battery at 10%. Wi-fi sharing manager and wi-fi sharing are listed in running services even with wi-fi off.

I do not want to root my phone. I have also noticed that in the Settings>wi-fi & networks, once I switch on wi-fi, every few seconds a brief pop-up 'scanning' appears and disappears, even though wi-fi is connected and notify open networks is disabled. So using wi-fi also eats up a lot more battery.

I am on KE8 - the Indian firmware. I have used Kies Air a couple of times.
[Galaxy S II General] ammarselo:
i've had my phone for a month now. No problems what so ever. Battery seems to be doing good.

there is something i cannot understand..

why samsung cannot make a comment about this problems..just to say sorry i will fix them!!!.

this battery drain is unacceptable for a 650 euro mega phone...

just looking at battery stats all the time and rebooting the device is not a solution and freezing apps in not either..
[Galaxy S II General] sandeep10:
On stopping wi-fi sharing through applications battery usage, it started again, but thereafter it appeared that there was less battery drain and now usage % has gone down to 8%. But this is not permanent solution.
[Galaxy S II General] dagrim1:
Hmmm, only now noticed it after watchdog was letting me know wifi-sharing was using too much battery... Very strange indeed as wifi is off AND wifi-sharing is disabled.

Froze it for now so we'll see if I notice anything in battery life. Very strange issue though. Using litening rom v1.4 btw (KF1 based).
[Galaxy S II General] Hrti:
Coming from HTC, I've found the SGS2's battery life to be great (even though the Android Process drains a lot, my battery life compared to the HTC days have been superb).

Nevertheless the last couple of days my battery has drained somewhat fast. I noticed that the wifi sharing process showed up in the battery usage history. After reading through the whole thread I froze the following apps: Kies Air, Kies over wifi, wifi sharing and wifi sharing manager.

All functions seem to work, even wifi tethering. Will report back on battery life after trying for a couple of days. Really strange issue though :confused:
