Lately my SGS running Froyo 2.2.1 has started acting strangely. There is an annoying bug I've noticed and I wondered if anyone else had noticed it or found a fix.
In Wi-Fi settings I've set the time out to 14 seconds, using OCLF, then I set Wi-Fi sleep policy to "Never when plugged in". I've found that this increases my battery life by at least three hours.
Lately this setting has been switching itself back to "Never" and thus my battery life is reduced. Has anyone encountered this or know of a fix?
Back up data and try a factory reset .Undo lagfix first if any .
does OCLF work correctly on 2.2.1 check the faqs .

Tried all that. I'm not using the lagfix component of OCLF as 2.2.1 doesn't need it IMO. I'm simply using the Wifi Timeout function, which does require Ext 2 Tools. All is compatible with 2.2.1.
I think I may have located the "bug". I recently installed Winamp and activated the wifi component of that. This of course requires wifi even in sleep mode if it is to enable playing of mp3 files over the wireless network. I've uninstalled it and will monitor.
..but are you sure this increases battery life....i mean if wifi is not enabled ordinary net functions are made by data phone network.....maybe your battery life time is related to some other thing ???
No, because I disable packet data when in a wifi network. There is still some gain in disabling wifi even if packet data is no disabled though as seeking a wifi signal does use energy. For this reason I also disable wifi when there is only packet data available.

Hey, in the last few weeks I've run into a very annoying bug on my phone. Wi-fi turns itself off after about 2 minutes. It doesn't actually "turn itself off" in the phone - and by that I mean that the wifi icon is still there, and I can see the signal strength, but the internet won't work.
In order to fix it, I have to turn the wifi off and then on again.
I've tried using the Wifi Fixer application, but it doesn't help. It can't seem to detect when I lose my internet connection.
I've also troubleshooted it, checking that it occurs on different routers/types of networks.
I'm sure it's a problem with my phone, but I dont really want to reformat my phone until Froyo comes (since I don't want to have to install all my apps twice).
Is there any solution to this? ;z
I'm on stock rom, JF3, with OCLF.
I have the same problem with my phone. My Wi-Fi at home works just fine, but when I go to my brother's house, I seem to occasionally lose internet connection even though it shows that it's still connected to the Wi-Fi. I have stock Bell ROM with OCLF by RyanZA. Oh, and to fix it I simply turn Wi-Fi off, and then on, and it starts working again.
Bump :x
Anyone have a solution?

my wifi works fine..it connects to my network..bt after its connected it keeps on scanning for other networks..which is unnecessary sinces its already connected to my network..n also its s battery eater..is there a way i can stop it from scanning for other network since its connected to my network??..thx

It sounds odd- how can your wireless scan when its already connected. Does your wifi status say - connected?
Either install superpower app from the market. It will make sure that your wifi doesnt drain your battery or you can install OCLF 2.0 from market and tweak the wifi settings to ensure longer battery life.
It does not scan when connected to a wifi, only when you open the wifi settings page, so it can present you with an updated list.
Concerning: possible reasons are low signal strength or a rom variant which uses a lot of power, JPY for example. One solution is to exchange with other wifi driver. Some custom roms offer less powerhungry wifi.

Settings wifi scanning off when screen off or similar .

I read on the Darky's ROM thread that this is normal android behaviour but yes it seams weird to me too.
I have a major problem with wifi on GingerDX & stock kernel, it drops the connection everytime it is idle, and it many times doesn't come back by itself or the statusbar shows it is connected, but there is no connection, and in these cases i have to switch it off and on. There is no encryption on the router. I set the wifi sleep policy to never. This doesn't happen on stock ROM. Any solution to this?

Set the WiFi sleep policy to "Never" to avoid WiFi going "ZZzzzzzz" when the phone is idle (lockscreen kicks in)
I mentioned that i already did that.
And it does it too when it is awake... i already downloaded many apps to keep the wifi awake but no success.
In this case it would rather seem you have a compatibility problem between the ROM and your Access Point / Router.
Try switching channels or secure your network to rule out your problem comes from tons of strangers using your wifi.
I think i switched channels before, and no success. The router doesn't accept connections from unregistered devices so even without password, nobody can connect from outside.

LOOOL ... MAC addresses are sniffed in a matter of split-seconds.
Anyway, since you are certain you already did everything in the book, and outside the book ... maybe try changing your WLAN cable past a new one.
There is no WLAN cable on the router, the antenna is connected directly to it. By the way 2 computers are connected through wifi and their connection is constant. But if it works on stock rom then there is something in the rom itself.
I suggest edit twilan.ini to make N standard work. This solved my wifi problems on SDE .
Search XDA for n standard on x8

I'm gonna test it for some time, I will report back if it worked or not.
I have similar problem myself as well. I even upgrade it to latest rom and it still does that. I already set wifi sleep policy to NEVER yet the damn thing could randomly decide to cut off. As soon as I wake the phone up it will re-establish connection. Ever single time. Why does it not try to re-establish connection while the screen is off? The funny thing is that I have no idea when it drops connection. The logging has no time stamp that I could track down events.
I believe sincerely that there's still some bugs to be rid of
Try enabling N standard, since i enabled it the wifi stays connected, for now.
i had the same problem.. U just have to use nAa or Alfs for cm7 kernel and rom which works with these kernels and no problems anymore
Hi!
A few weeks ago I flashed CM9, since then I experience an enormous battery drain when I'm connected to the wifi of my university ("eduroam").
The "Android OS" process then consumes a lot more ressources than usual. At my home wifi everything is normal.
And when I turn off wifi at the college and use normal mobile network, everything is also fine.
Pictures:
s14.directupload.net/images/120513/erjgvknk.png
s14.directupload.net/images/120513/mau8hlfo.png
What I tried to fix it:
-flash different modems
-turn off location via wifi
-use different "EAP-Method" (TTLS and PEAP are supported by the college network)
I would be very happy if someone could help me!
Thanks in advance.
modems are not related to wifi... consider instead a different kernel..
I'm having the same problem, but on an i9100 device. Have observed this problem using different roms/kernels, all with similar result.
It seems the problem is not related to roms/kernels. When I'm using my home wi-fi network, their is no battery drains at all. The drain only happens when I'm connected to "eduroam" access point.
Monitored using BetterBatteryState, find long wakelock time for "wlan-rx-wake".
Now I just disable wifi when I'm not using it in an eduroam area.
Problem confirmed.
For me it's even worse. As soon as I add eduroam to my list of wifi access points, the drain is at 60-70 mA even on my home network.
Could this be related to the encryption or access control of eduroam? "Normal" wifi networks use wpa or whatever but not this weird PEAP or EAP, etc.
I have the same problem. Some networks drain the battery really fast, while battery drain at other Wi-Fi networks is normal...
Hi everyone
I have a profile that that kicks in every 30 mins from 8 am to 9pm, to sync my account. I have set it up to use wifi first, but if there is no wifi connection it will go to my mobile data instead.
Now here is the problem if my phone is on standby it always connects via mobile data regardless of a wifi connection is available. But if I am using my device at the time when the task runs then it will connect to wifi. I have checked my, keep wif on in sleep option and it is set to always.
Could anyone explain as to what this is happening?
Thanks in advance
What is your Android version?
I am currently using a custom rom called exodus which is currently based on marshmallow.
Check if Tasker is excludied from Battery Optimization and whether Wi-Fi is not deactivated while the phone is in sleep mode in Settings/Wi-Fi/Advanced/Keep Wi-Fi on during sleep.
yep tasker is excluded from battery optimisation and the allow wifi during sleep policy is always.
If you're turning wifi on with tasker action wifi turn on, try instead of that shell script "svc wifi enable".
Ok thanks, I will let you know the out come of this. I was using secure settings to enable Wifi as the command built in tasker, is not compatible from kitkat and onwards if I remember correctly.
I found out "svc wifi enable" command does exactly the same thing
Discovered I'm having the very same problem on cm13 and the batch jobs have been done by initialized mobile data. Finally found out a solution to initialize wifi instead of mobile data. I've no limited data plan, but wifi is more battery friendly.

Do you actually wait for wifi to connect?
Does your phone do the low power screen off wifi thingy?

Yes under normal circumstances it takes about 20 seconds to connect.
No because for some reason my wifi will only switch on if the screen is on.
I also have uninstaled my custom kernel, but this issue still appears from time to time.
There's a setting in wifi connection settings that you can set to that says "keep Wi-Fi on during sleep"
This same setting is often repeated in battery apps like powernap, naptime, better battery saver etc.
Even though the wording is the same, I don't believe they are all touching the same setting so go find those apps if you have them installed.
Also, disable all native battery savers (including Samsung 2 or 3 different ones,, doze, battery optimization etc etc just to see if your problem goes away.... Which it will. At least you'll know though
I have the same problem with Wi-Fi connection.
I have a profile to turn Wi-Fi on and try to connect when certain conditions meet and the screen is off in that case.
It seems that the phone has difficulties turning Wi-Fi on and connecting to it when screen is off. Tasker does manage to turn Wi-Fi on but the phone somehow does not connect *reliably* in all cases.
Tasker is excluded from battery optimization, Wi-Fi on during sleep. I tried turning cpu on for a short time hoping that it will connect, but still no result.
The only possible solution might be turning the screen on briefly at that moment.
If anybody has a better idea, you are more than welcome to share!

I can certainly say that turning the screen on will enable wifi, as I have resulted to this as well. But unfortunately I do not know any other solutions to try.

My Wifi is set to always "keep wifi on during sleep"
I'm going to resort to flashing stock rom again and see if that helps. As I am only using doze and amplify to save battery, all settings for that has been adjusted to the guide I found.

Before reflash, just disable xposed and see what you get... I will bet half of this soft taco I'm eating your problem disappears with greenify and or amplify. I'm not saying don't use them at all... Just make sure it works without them. I used to have some serious battery apps, but found after disabling, my battery was IMMENSELY better. And I had no config to deal with. But first things first... IT'S without a doubt, no question, a battery app setting or a system app that's being put to sleep that should be white listed
