I set up the WiFi standby rules to "never", so wifi should be always on even when my device is in standby mode.
This worked very good at the beginning, but since some days WiFi is NOT kept alive. As soon as the device is going into sleep mode i will lose WiFi connection. The WiFi standbye rule is still correctly set to "never".
Thats really lame because i use locale to update my RSS Feeds at home over WiFi on certain time slots. But i get no updates since wifi is not active when the device is sleeping.
Anybody an idea what the problem is? As i said it worked for 2 weeks and suddenly its not working anymore.
Won't that drain the battery to Kingdom Come if you do leave it on on standby? I used to do that on the Tytn II I used to have, and the battery died after 2 hours!

well i wouldn't say 2 hours, should be more than that. But i'm only activating wifi at home, and at nights my device is plugged to ac adaptor. So battery is not an issue in my case, and i want to use the better bandwidth at home. I just dont know why is suddenly stopped working...
Settings > Wireless controls > Wi-Fi Settings > Menu > Advanced > Wi-Fi sleep policy. When finished press Menu and then Save. Done.
The "Menu Button to save" Hint did it! thanks!
I always chose the option, but forgot to save via menu button and pressed the back button.
The strange thing here is: when i was coming back to this menu later it would still show the correct setting (WiFi always on), even though i hadn't saved it via menu button. But it wouldn't work, because wifi would be deactivated.
The back button will save your last selection, but won't activate the option!
This is really one of Androids problems: you just don't have one standard way of interacting with the system on many levels. Sometimes "back" button is enough (or the only way) to store your data, other times you have to press hardware buttons to save...
hmm the problem seems to be elsewhere: today in the morning the connection was lost again when i took the phone out of sleep mode. i could see the wifi icon, but the apps couldnt connect to the net (my rss feeds hadn't been updated).
Seems like each time i deactivate wifi manually (when leaving home) the wifi rules settings will be lost, and i have to change the wifi rules again and save the settings. Otherwise wifi won't be kept alive...that's really annoying.
maybe i have to download the "keep wifi alive" app after all from the market...
What make and model is your AP?
it's a netgear router, i will check the exact model today and post it here.
hmm i forgot to check the model, but i changed my router settings yesterday.
the router was set to disconnect after 60 minutes, when the connected device is not using the connection.
i changed that, so the connection is not reset at all, but still as soon as my device goes to sleep mode the wifi connection is basically dead.
After taking the phone out of sleep mode, i can see the "wifi connected" icon still there, but no app has any internet connection.
I'm sure there are others who have experienced this problem. Even though I show no wake locks my phone drains at an unacceptable rate while on my Wifi at home. My phone can have a 60% battery when I go to bed, and be almost dead by the time I get up. The only clue that shows up in Android System Info or Spare Parts is network usage by '0' which is something with root access.
This is happening regardless of Rom. I've tried stock, Syndicate Frozen, Urban Fury, Bonsai, Stock Plus, and maybe another I'm forgetting. They all drain the crap out of my battery with wifi on at home so obviously this isn't a rom issue.
This leaves me to believe that either something on my network is forcing data to my phone keeping it from deep sleep, or the router itself is the cause. Turning on my phone to 3G, my battery life is spectacular overnight. It deep sleeps like it's had a case of beer with a bottle of nyquil as a chaser before bed. 1% an hour.
So, I've ordered a different router to see if that's the issue. I've googled my current router which is a D-Link DIR-655 and seems like others have had similar battery drains using that router but no one can emphatically say it for sure is the router. Guess we'll see when the new router arrives if it is indeed the DIR-655. Otherwise the next step is disconnecting everything else that is connected to my network (3 computers, 2 printers, XBox, Wii and a Blu-Ray player. I just wanted to point out to anyone else having issues with wifi and weird battery drain, that it may not be the phone that is the problem.
I too have massive battery drain when using Wifi. It doesn't matter what Wifi network I'm attached to (work/home/friends/etc), I burn about 10% + per hour on idle; whereas on 3G is burning only ~2%/hour on idle. On stock, Wifi was my battery saving grace.
I've just given up on using Wifi for daily use. I use 3G for everything now.
I hope the newest version of SFR (whatever the new one will be called) will remedy this problem I have. I haven't posted about it in the rom thread since I had a feeling it was just my phone or another bad flash in CWM.
I've been using that OS Monitor app to try and find the problem. On 3G all the network interfaces have static receive and send amounts as long as I'm not doing anything that requires data. Connected to my home wifi, there is a constant trickle of data.
When I let the phone sit overnight, there was over 4mb of data received, even if I turn off any kind of auto syncs on the phone.

Don't know if this will work for you but you can try. In the wifi settings click the menu button and select advanced then set the wifi to never sleep. I know it's counter intuitive but I went to sleep last night at 61% and woke to 57%. Wifi has been fine for me since changing that policy in the wifi advanced settings.

Mine has been set at never sleep since I got the Epic in September, and I double-check after each custom rom flash. Good looking out though.

Same here. Mines always been set to never sleep.
Edit: I just tested my phone on my work's wifi network. CPU Spy says it's going into deep sleep just fine. OS monitor shows a static data received/sent number once I was connected. Obviously something about my home network is the problem.

That is my general experience, too. These settings usually keep my WiFi usage low overnight.
But some nights, inexeplicably, I will wake up to find a large battery hit from WiFi. I don't think it is my WiFi router's problem, unless there is some outage duirng the night I am unaware of. Come to think of it, I had that problem last night but did not investigate early this morning before I left. When I get home, I will check with my laptop to make sure my router is running.
I have noticed this too and in particular over the past few days. I'm on the latest bonsai build which does have amazing battery life on 3G but now wifi does draithe battery much more than 3G. This never happened before. I have had my wifi set to never sleep. Any other suggestions?
Obviously haven't tested it overnight yet, but I shut down my one laptop and the constant data trickle immediately stopped. Right now it's looking like something my computer is running might be the culprit. Going to leave it sit overnight to see how it goes.
I found the cause of my drain! Narrowed it down to something from my laptop as when I shut my computer down at night, the drain would go away. The culprit was the HP Printer software for my wireless printer. Once I uninstalled it, the drain went away. Noticed in resource monitor that HPZinw12 was sending a constant stream of data from my computer. Why in the hell it would be also sending to my phone keeping it from sleeping seems pretty odd, but I recommend if anyone else who is having battery problems over wifi and happen to also have an HP printer, you might want to look into this as well.
I'd also add that my solution to getting rid of the problem and still being able to use my printer was just to uninstall the crappy HP software that came with the printer and add the printer through the control panel and let windows 7 install it. It doesn't throw on that HPZinw12 file that apparently polls the entire network constantly.

Since I have been experiencing similar symptoms intermittently and I also have a WiFi printer, I have tried to eliminate this as a potential cause. (I don't run an HP control app on my laptop, but already map the printer directly in Windows 7 like you suggest.)
In my case, I still get the excessive WiFi battery drain, and low battery level upon waking, sometimes overnight. But other nights the problem does not occur. So lately I have made sure that my laptop and printer are powered down before bedtime. And like you, a always have my WiFi sleep policy set to "never" and have a strong WiFi signal. But last night I still had the problem, and awoke to find the battery drained to 45 percent instad of its typical 90 percent.
Interestingly, I noticed not only high WiFi battery usage but also high "Cell standby" usage attributable to the well-known Time Without Signal problem -- and this despite my habitual use of the Airplane toggle workaround, which usually works.
Somehow, something caused both WiFi and cell radios to go crazy overnight.
BTW, I run a stock, unrooted Epic.
So far with SRF v1.1.1, my Wifi is back to normal.
On my work network, I've dropped 4% in 3.5hours with my work email syncing every 15mins. So that's pretty good usage given that sync interval.
I also do not have a printer at home, so the printer bit wouldn't have been a cause for me.
While the printer thing took care of the biggest problem for me, I still don't get as good of battery life overnight leaving my phone on WiFi rather than 3G. There is still something my computer is doing that wakes my phone up occasionally, but at least I'm not going to bed with a 70% battery then waking up to a dead phone. At least I have it narrowed down to one computer (total of 3 on my network), as when I shut that particular one down battery life for my phone is back to 1% an hour while sleeping. If I had to take a guess at this point, might be something with media sharing as I use that one as my primary location for music/videos to stream via Windows Media Center.

How do you know it is your computer? Have you tried just turning it all the way off?
Do you watch the services running on your phone? I routinely stop the DRM service, for example.
Except for the mysterious episodes when I experience this intermittent problem, my overnight battery usage is typically about 1 percent per hour.

I've tested over a few nights with a mostly full battery off the charger and reset the timer on CPU Spy. The nights I shut that computer completely off, I get very little battery drain and the phone is mostly in deep sleep according to CPU spy. When it's on, the phone shows a good chunk of CPU at 800mhz and more battery drain.
I have a brand new Galaxy S4 and have been having some serious issues
WiFi -
I've googled around and people seem to be having WiFi issues but only with DLINK routers, my issue is kind of different. I don't have a DLINK router, i have a brand new Vodafone router. The router is in my sitting room and when I'm in that room the WiFi is fine but when i'm upstairs in my room etc the WiFi signal drops a lot and it disconnects and reconnects almost every 5 minutes.
So far the fix has been to turn off WiFi power saving mode but when I do that everytime after a while when I try to use Google Play Store to download something I get a 491 errror. (UPDATE: The google play error is still there when using wifi power saving mode or not)
I've tried changing my encryption cipher in my router away from AES but again no luck. What can I do?
Battery -
Only got the phone yesterday wasn't focusing much on battery life but went to bed last night charged it, woke up used the phone for around 2 hours and was at 49%. I then ollowed every "tip" on the net turned off nearly ever feature put on power saving mode and the phone lasted from 1pm - 11pm and was at 5%
Anyone any thoughts?
I have come to the very certain realization of late that WiFi is using up all of my battery, and I am trying to figure out how/why. This trouble began when I updated my wireless network and essentially added an upstairs wireless repeater, or at least that is what I think. It seems to me now that I think on it that my battery troubles began soon after I added said repeater. Anyways, 2 nights ago I fell asleep around 1:30am after my shift ended at work. I had 100% charge and at 6:30 am 5 hours later when I woke up, with wireless off, I had 98%. This is what I was used to with my phone before. I proceeded to use my phone on and off throughout the day and at about 7pm I still had like 68% charge, which is great I then turned on my wireless to connect to home network and pull down a file. I went to bed early, and left wireless on throughout the night. My phone burned through more battery without me using it and just WiFi on than it did the entire 18 hour period before. I woke up with 15%. Here is what it looks like. Anyone have any idea what may be going on?
I have an Asus router that can also be configured to be either a repeater or an access point. I am now thinking I perhaps had it setup incorrectly. I set it up now as an access point with a different ssid from my downstairs router. Should not be too difficult to switch access points when upstairs or down. I half think it was bouncing between routers before when they had the same ssid, which was causing needless wifi useage. Here's hoping this helps.

Would it be possible for you to tap on the graph so we can see the breakdown of awake time/screen time/mobile network connection uptime, etc and show us that?
I just did this now. Does not coincide with my first screen shot. Also, not sure if I am reading this right. According to this, looks like my wifi was on all night, but I know for a fact I turned it off when I went to bed, which is why I only burned through like 4-5% during the night.

In the WiFi settings on your device, hit the menu button. It should bring up the option to pull up the advanced settings for wifi. It looks like the pic. If you turn off the scanning and smart network switches, that should help some.
The problem was definitely do to the fact that I had upstairs wifi configured as access point with identical ssid to downstairs. After changing that, I am now getting killer battery life. Close to 2 days on a charge.
Well, my problem went away or seemed to, but after installing BOC4 firmware 2 days back, they seem to have returned. Here is a screens hot of last night. I turned wifi off when I woke up around 4:30 as I noticed significant night time drain when phone was idle. I went out to play a gig last night around 5, and find it interesting how my problems got better while away form home, only to rerurn when i got back. Not sure what is going on with it.
I've had my V20 for just over 2 weeks now and found something strange regarding wifi.
Normally I set my phone to keep wifi on, even when asleep because cell reception at my office is spotty and staying connected to WiFi used to keep the battery taking a hit during the day. But, I left my phone off the charger overnight last week and saw my battery drop 11% in just under 8 hours. That seemed higher than my old phones so I installed BBS to see if anything was misbehaving when I'm not using my phone. To my surprise, no apps were causing a large number or long duration wake locks but my phone was only in deep sleep for 25% of the night when left off the charger.
While I was testing different configurations I left wifi on, but set it to disable when sleeping and sure enough, my phone stayed asleep for 80%+ and the 8 hour drain dropped to 5%. I havent been able to find any other combinations of settings that get the phone to sleep.
Has anyone else seen thing on their V20?
Only 4% drop at worst over night with Wi-Fi left on here.
Hey shwnr11, thanks for the reply. Just to clarify, you had the setting "Keep wifi on during sleep" set to always as well?
I always have wifi on at home, but unless I set wifi to turn off when sleeping, I see the drain.

Yep, that's the one. Different wording on the Verizon V20, but same idea. Guess I've still got some searching on my end!
