Every time I put the Nook Color in standby, it loses my wireless. Upon taking it out of standby, it doesn't reconnect automatically- i am forced to actually go into settings- wireless before it finds my wireless network.
I have installed Spare Parts and set the Wifi sleep policy to never, but it still doesn't automatically connect to my wifi network. Even if I turn off my wireless and turn it back on via the widget I have on my desktop, it won't connect. I am forced to enter into Settings- wireless every time.
Thanks in advance.
bumping once- seriously nobody else has this problem?
Yes I have this problem too but don't know how to fix it. I just turn wireless off then back on.
No issues here at all, reconnected within seconds. Rarely do I even notice it was disconnected at all.
Are still on the 1.0.0 firmware? I had this issue, but since updating to 1.0.1 (which stated it improved wifi) I haven't had this issue.
Yeah, I see this too. I saw there was a hack somewhere to make it persistent. But that would certainly drain your battery more. It didnt bother me all that much, but if you need it for Gmail/texting/Google Talk, I could see why you would want it to be persistent for notifications. Didnt bother me, since I have a phone too.
By any chance did you install the wpa_supplicant to enable use of adhoc networks? I've only had the issue since I did that. More info below:

Same here mine only does it since the install, but I knew that going into it as well.
I always had that issue, before the adhoc fix and after. Learned to livevwith it. Haven't upgraded yet... still on 1.0

Same exact thing is happening on mine. I have AutoNooter v1.01 currently and every time my device goes to sleep the wifi turns off, which hasn't been an issue until just recently.
In the past as soon as I would turn back on my device, the wifi would reconnect. Now I have to manually go to Settings> Wifi to get it to reconnect to the network.
I have tried the SpareParts fix, but it doesn't help. I have also tried on different wifi networks, but the connection issues still occur. Any feedback would be greatly appreciated. Thanks.
I also have the same problem, running auto-nooter. The only thing is that my signal never reconnects, I have to manually reset my internet router in order to get it back. Rebooting, or turning off Wi-Fi settings within the device doesn't help.
The only thing that works is never allowing my NC to fall asleep on it's own. If I manually put it into standby mode, it works fine.
I have the 1.0.1 update, and I called BN, but they only offered to replace it. I have it tricked out just the way I want it, so I'm just going to hold on to it for now.

I had the same issue as well on 1.0.1.
I've found that the wifi doesn't turn off for me if it is plugged in and charging. I did enable wifi to never sleep w/ spare parts, but it still turns wifi off when it goes into standby when not charging.
My wifi stays connected with the screen off, but some times when I turn the screen back on the wifi disconnects. I know this happens because I am listening to Tune in radio and it does not disconnect until I turn my screen back on.

Mine does it.
I have to turn off then on.
This is only after the adhoc patch. I think I'm going back to infrastructure only.
I'm using wake timer:
http://www.appbrain.com/app/waketimer/schaze.waketimer
Same idea as SoftLocker but lets you also setup a timer where after a certain amount of time the system will actually sleep. Useful for night time or other extended periods of non use where you don't want to drain the battery.
Problem is that it does not activate on boot like SoftLocker and also after the timer expires and it goes into sleep, WakeTimer does not reactivate on wake.
Edit- after testing both programs I think SoftLocker is better. Running battery tests, there was not significant battery drain having SoftLocker on all the time. A few % overnight, probably related to the accumulation of e-mail, tweets, RSS downloads etc, but really minimal. Like that Soflocker can be checked to start on startup.
+1 for SmartLocker
This has happened for me as well. My remedy was to create a Tasker task where it's set up to connect to my SSID whenever it's detected.

When wifi is turned on and the phone is otherwise idle, there is a constant but small stream of data up and down. I have NetCounter installed which monitors wifi as well as cell data. This morning, when I turned the phone on, with the wifi counter at zero, I enabled wifi and then just let it sit on the desk for 4 hours. At the end of four hours, there was a total of 3.83 MB of wifi data usage, 3.52 MB received and 320.7 KB sent. Also having wifi on when the phone is idle eats up the battery. Starting at 100%, at the end of the 4 hours the battery was down to 64%. With wifi off, after sitting idle for 4 hours it would still be above 90%.
By the way, the phone is now rooted with sre 1.3.1c and with lag fix installed, but the wifi has behaved the same from when the phone was new, and I ran it for about a month stock. I'm just curious if this is normal operation for wifi. I have read in other threads that some leave wifi on all day without much battery usage.
When I first got the phone, I thought that it might be some application running in the background that was causing the data usage, so I installed ATK and experimented with killing everything, but the data usage was constant. (I can also see the data usage on my router because the wifi light flashes continually when the phone's wifi in turned on, and is solid unflashing when the phone's wifi is turned off, assuming the laptop is not connected.) I was unable to stop the data usage by killing off applications.
Any ideas? Thanks.
Did you agree to send anonymous usage data to Google when you configured the phone?
Interesting thought. Normally I never send anyone any data, unless I'm forced to. Would the tech at the store have set this up? Where do I look to check?
Edit: if you mean "use wireless networks" in settings | location and security, it's usually on, but it doesn't make any difference to the wifi data usage if it is turned off.
Gmail does push email, so does exchange. Are either installed? Any widgets? Facebook accounts?
There are many core apps that use data, tell us more about your config and we can help pinpoint it.
I have the google and youtube widgets, the Android power control widget, and the juice defender and juice plotter widgets. The last three were installed after I started trying to find the solution to the wifi issue.
I have Gmail installed. However, Auto-sync is always unchecked, and even though I leave bacrkground data checked most of the time, if I uncheck it, even with a reboot, the wifi data still goes on.
Installed applications: AndExplorer, Any Cut, AutoKiller Memory Optimizer, Google voice, Grocery IQ, JuiceDefender, JuicePlotter, Listen, Maps, Market, My Tracks, NetCounter, OruxMaps, Quadrant Standard, Rom Manager, SL4A, Startup Auditor Free, Titanium Backup, XDA. All the root apps were installed recently.
Installed sre 1.3.1c recently, which removed samsung and at&t bolatware.
That's all I can think of for now. What else would be helpful to know about my configuration?
I don't see it on your list of installed apps but when I installed (ad supported) MailDroid, I noticed I got 4MB of data downloaded in 4 hours while the phone was sitting idle, charging (not even on WiFi. It was on my 3G!). When I Force Stop MailDroid, the data activity dropped to near zero.
Could it be some ad supported apps that run in the background? Data leaks?
I have the stock mail application, which retrieves mail from two accounts.
Grocery iQ has coupons. I use the program for inventory, so I never even look at the coupons page. Anyway, that app does not run in the background. You can't find any process associated with it unless you start the app from it's icon.
Startup Auditor has ads in it. I tried disabling it (with Startup Auditor) but that did not make any difference in the data, even after reboot. Anyway, that program was added since I've been working on this.
I don't think any of the other apps have ads in them.
One other thing I'll mention. There have been two occasions when the data stream stopped completely while wifi was still turned on, each time for a period of about 20 to 30 minutes. I could see this from the wifi activity indicator light on my router. This happened about two weeks apart. The more recent one was yesterday afternoon right after I made the OP of this thread. In both cases, I could not correlate what caused the data to stop, nor what caused it to start up again. But at least it seems to indicate that there is something causing the data to flow, and that it can be inactive while wifi is on.
are you sure its not another device that is using the wifi and not ur captivate

Yep. There's only the laptop and the phone. The laptop is on the ethernet connection, hard wired. The laptop has an on off switch for the wifi. It's off. Also, the indicator light goes solid when I turn off wifi on the phone, and starts up again when I enable wifi again.
Tonight I decided to put DG's Cognition on the phone. After I Oden3 one-clicked to stock UCJF6, I checked the wifi, and sure enough, still getting the constant data stream. When I bought the phone, I never really became aware of the problem until after I had loaded a number of apps. But here it is in the "just out of the box" state, and it already driving my router crazy.
So now I don't know what to think. Is this normal for all Captivate phones? Is this a hardware problem on this phone? Something else? Btw, the flash to cognition went smoothly, and the phone is running well, but the data stream is still there when wifi is on.
I wouldn't get all in a frenzy just because your router is blinking. Your router blinking doesn't mean your phone is downloading something. Install an app that monitors your wifi data usage. If it reports unusually high numbers then come back here.

Please read the OP and the whole thread. It isn't that long. True, while I was in the midst of flashing Cognition, I didn't take time to install NetCounter on the stock rom and take time to check the actual data flow. But the fact that there is actual data flowing when the indicator light is flashing is established.
I've uninstalled MailDroid because of the annoying ads (and because I thought it was doing unnecessary downloads at night). I woke up this morning and NetCounter shows 13MB of data downloaded for Today (from midnight to 6am). I suspect it's the 4 windows (tabs) I have opened in my Browser. Two of them were full (desktop) websites that have banner ads in them. Hmm...
Less than 1MB of data per hour is not a big deal. I'm sure it's a combination of apps that pull or sync data from the internet. Or it could just be an app you have installed that's downloading ads like RexEscape said.
Also, do you have the wifi sleep policy set to never? It should be set to never for best battery life.

What do you show for data usage when your phone is idle but wifi is turned on, meaning nothing you know of would be using data? Would you mind doing a brief test like that? Thanks

It appears to be drawing data without any apps installed. I assume that after flashing odin3 one-click to the stock rom, the phone is configured almost exactly like it would have been out of the box.

Just checked it. It is set on Never now. I'm pretty sure it has been set on never since I first started trying to optomize battery life, and discovered the wifi issue.

Thank you very much.
I hate to bring this one back from the dead but I am having the same issue. When watching network usage in SystemPanel, I am getting 0.6-0.2kbps up and down constantly. Then when I switch Wifi off, it sits on zero. That seems to indicate something directly related to the relationship between the phone and wireless routers and not a specific app or general setting. Any ideas? Thanks guys.
I also just noticed that under Wifi settings it will pop up saying "Scanning" every 2-3 seconds. It does it whether network notification is checked or not. Not sure if that is normal behavior or not.
Greetings--long time reader of the forums but n'er a post'r. Hoping to change that obviously.
I'm currently working through what I believe to be a 'bug' in my Cappy, running a custom ROM (Apex) but am debating if it is a lost cause since it's been tough getting the dev to respond to a request.
I prefer my wi-fi to sleep when it's not being used since I rarely ever use 2g/3g data (I physically turn it off when not using it, and may go weeks before switching it back on) as I'm always at home or work, or at a cafe with free wi-fi. I use FB, Twitter, Google Reader, and some minor web usage via browser when at home/at work, so it's not like I'm constantly flipping my phone on to use the services.
I guess my question is: should I just say to heck with my wi-fi sleep bug (it doesn't sleep even though I select the "sleep when screen off" option--it will sleep but only once and the setting will revert to "never" after it wakes back up) and just deal with wi-fi being on all the time? If it's on and stays on throughout the day with very few calls from gmail, none from Twitter/FB since I have all that syncing turned off, does it really chew through that much battery since it's not turning the radio off and on?
There are two settings.db files that I believe are corrupted to some degree on my phone, and instead of piddling with it any more, I'm about to just give up and deal with it--I've goggled and checked to find some hard evidence that allowing it to sleep or allowing it to stay alive is better in some way for battery life. I get about a day and 3/4 of life out of it. A lot better than some folks but I feel I could squeak out another 1/2 day out of it if I had that sleep mode working.
Alright I hate to ask this question, but my searching and reading is not leading anywhere. I recently upgraded to GB (Illuminance with Corn) and I'm loving how fast my phone is. The only problem I notice is how fast my battery drains while on WiFi (Wireless N with WPA2).
Example: I was at my parents house for 2.5 hours, but didn't bother turning wifi on. I only lost a few %. Once I got home, I kicked on the wifi and within an hour I lost 20%. It appears that when wifi is turned on it is almost constantly in use. I checked for rogue apps and data usage and found nothing. The only thing I notice is that every 5 seconds (yes, I actually timed it) it is polling for new networks.
After doing some reading I checked and the build.prop mods are in there (wifi.supplicant_scan_interval).
Any suggestions on where to go next?
Recap of phone config:
Rom: Illuminance 3.01
Kernel: Corn 7.06
Modem: KK4
Yeah...I've noticed that the build.prop tweaks for wifi scanning don't actually seem to change the scanning interval on gingerbread ;/
Try going to, Settings> wireless and networks> wifi settings> menu button> advanced> set wifi sleep policy to "when the screen turns off"
That'll help while it's asleep.

I switched my ROM from Apex to Illuminance to test a theory that this functionality would work as it had in the past on Apex ROMS. For whatever reason kernels/framework were swapped in a newer version of Apex that killed this very helpful functionality. Once I switched to Illuminance and enabled the functionality, it works again and I get 2+ days worth of battery life with moderate usage (rarely a video/music played, but I do a lot of browsing and email usage/fb/twitter usage is high).
It drove me nuts on Apex trying to figure out the issue. I had thought my settings.db files that control the wifi functions had gone corrupt and the dev ignored any requests for assistance.
Glad I made the switch.

That was the first thing I noticed. The ROM defaulted to Always On. I changed that the first day. Unfortunately, I still have the issue. As it stands, I only get one day at most out of my charge. The only thing I let sync is the gmail account. I mostly browse and talk less than 1 hour per day.
I'll try to do a more statistical approach when I get a chance. I'll see about taking readings ever half hour with the wifi on and no other use.
I was under the impression that if the phone downloads data over WiFi it actually uses less battery than if it downloaded data over 3G. When I'm at home, I leave my WiFi on intentionally when my phone is asleep so that my incoming email is more efficient since I have WiFi available.
Am I wrong here? Just curious if I've been mislead all this time.
I don't think you're wrong. That is why I always use wifi at home. I think I found some errant scripts that were running and causing the excess battery drain. I have taken those off.
I'll probably master clear and reload when I'm no longer on call this weekend just to make sure I got everything.
Do you leave your GPS / WiFi on all day? I never leave the GPS on due to I believe it kills my battery in half the time. Though using a weather widget I would like to have it update based on my current location. WiFi is odd, I have the sleep policy set to turn off when screen is off but I have a feeling it only works 50% of the time. Also with GPS talk what is sensor aiding?
Any apps out there that can best control there features so I can leave them on at all times?
Thanks

I never use GPS.
Sometimes I let WIFI stay on for a whole day, mostly becuse I forget to turn it off.
I usually just shut mine off unless I am using them. I am consistently checking my notifications, so I notice if one is left on when I shouldn't need to use it.
You can try using the power control widget on your home screen. That way you can easily see what is on/off.
GPS is off unless I'm using it but WIFI is always one so long I know where ever I'm at has a connection. I've noticed my phone uses more battery while WIFI is on disconnected than actually connected. Although it is possible to fix that by tweaking wifi search intervals (I'm just lazy about it)
I leave them on all the time. I do toggle bluetooth depending on when I want it. I can't really see any significant abnormal drain due that.
Hey guys --
I did a search and while there is much discussion of deep sleep problems, there is no clear way I could easily find to identify the cause.
I have CM7.20, the MiRaGe latest build on my NC, with the settings listed in my thread (see the sig). Recently I noticed that it is not entering into deep sleep, indicated by losing ~20% battery while it is asleep overnight in about 8 hrs. Battery results tell me it's "WiFi" taking like 30% of the battery, which seems quite odd, since I had it set to turn off WiFi while the screen off unless connected to the charger.
Any clues on how to identify the problem with deep sleep?
As for usage, I am using my NC 99% of the time with the following apps:
Moon+ Reader (probably 70% of time)
YouVersion Bible app (most of the rest of the time)
Dolphin Browser HD (maybe 2% of the time)
Enhanced Email and MailDroid - very occasionally but they are checking mail on 15 min intervals when wifi is on.
I have a ton of other apps installed but I almost never use them except for these.
Any help on how to determine what is causing the NC to not go into deep sleep will be immensely helpful. I have a 2-week Euro business trip coming up next month and I would really like to solve this before then.
Thanks!
Better Battery Stats might help. Try turning off sync before bed and see if you still lose 20%. If so, it's definitely some app that's the culprit. Grab something that will tell you what program is using data and how much/how often and you should be able to isolate it pretty quick.

OK, but it should be turning off wifi, and therefore sync for ALL apps, when it is asleep. Can an app override this setting? That's my guess, is some app is doing this. How can I ID that?

Like envygreen said use that app to track wakelocks. Even if wifi is off, some app may be applying a wakelock to try to sync.

Alright, I'm on it
So last night I finished charging it and read for a couple of minutes, then put it to sleep to see how it went overnight.
My Wi-Fi sleep policy is set to turn off wifi when the display is off.
When I got up this morning I checked it and it had lost over 10% battery over night, and I checked BetterBatteryStats and I think it is going into deep sleep but maybe not shutting off wifi.
I have attached the screenshots from BetterBatteryStats, and I think I need help interpreting them and finding the cause.
ok, so here I am replying to my own thread... If I am reading this right it seems to be looking like my wifi is on the entire time, not only when the screen is on. Is this the right way to read this? In this case, it looks like "Wi-Fi sleep policy" being set to "When screen turns off" is not actually working... right?

It sure looks that way to me too. It says wifi on 8 hours. Did you try toggling the setting a few times? Also you are on Mirage and he may have done something in his tinkering that messed that setting up.

yeah I did toggle the setting on and off, and in fact before I had it set to "On during sleep if plugged" for a long time, recently changed it, thinking maybe this was the cause.
But it does appear that maybe this is what is killing the battery. There doesn't appear to be any network activity when the screen is off, just looks like the wifi radio is powered up.
Any advice?

Hmm. that seems like an extreme step, but maybe ... wonder how much of the snappiness I will lose.
EDIT: OK I switched to CM7.2 stable. Nice I didn't seem to lose any settings. Let's see how it goes. Thanks for the advice, I'll report back here if it still does the same thing.
Also uninstalled beautiful widgets... figured maybe that could be causing an issue.
Oh, and I probably had a SOD kernel patch applied... perhaps that was the problem too
guess I should change only one variable at a time for a good test, but in reality I just want to get it fixed and not really diagnose it.
I was having a similar problem...what I did was run the V6 supercharger script, granted i am running CM9 atm but it took care of any problems I had with battery life and wifi signal.
Question: does having WiFi on keep the phone from going into deep sleep at all?
I have found that my phone is not going into deep sleep. I checked what is holding wake locks, and the time with wake locks is way less than the time the phone has the screen off, so it appears it is not deep sleeping, even though there are not wake locks.
I have an extended battery, so I get good battery life, but always interested in improving it. But I also have this thought that if I have to turn everything off, and only synch when I turn the screen on, that is not ideal either.

Get CpuSpy free on play store. It will tell you exactly how much deep sleep you are getting.
Having wifi on all the time should not prevent deep sleep. Only when things use it does it come out of deep sleep.

I have CPUSpy Free, and that is how I know I am not getting deep sleep. My challenge now is to identify why.
OK, so it seems that CM7.20 stable definitely fixes things. I didn't flash the SOD fix, so maybe the SOD fix was preventing deep sleep before, or maybe something else in the kang build was preventing deep sleep with wifi on when the screen is on.
However the better battery stats still seems to say my wifi is never actually going off. I am not sure I am interpreting the results correctly. It looks like the wifi is on all the time even though it's set to turn off when the screen is off. But I can let the NC sit on my night stand overnight and lose only a couple of % where it was like 10+% before. I still think my problem was due to some app that updated and not the ROM because the problem started weeks after I last updated the ROM.
