i just got my nexus, digged around, updated to cyanogen, rooted.
i have a problem that on my old touch hd i didnt have:
the data connection is always on?? doesnt android know to close it when not in use so it will save battery charge?
thank you
on the nexus one it works a little different, it shows the 3G icon but that does not necessarily mean its doing anything. only when you see the two up/down arrows lighting up and flashing is there 3G data activity going on.
i guessed that, but, it keeps the data connection open? even without transfer it still uses power, doesn't it?
it is always connected in a way, all it does is ping the cell tower every 10 minutes to have an established point on reference. this by its self does not draw to much from the battery as you would expect, only when data is requested does the radio kick in to full power, so no worries that it will drain your battery. The thing that will kill your battery the fastest is that beautiful screen. try to bump it to 60% thats i nice brightness but yet saves on battery. also keep in mind the battery needs to go through 2 or 3 battery charge cycles for you to get the most out of your battery life.
average real world battery life should get you about a day and a half of bettery.

This is how all modern smartphones work nowadays. They all keep the connections "on" 100% of the time.
It's funny because I asked this question a few years ago
The answer I got was that it actually uses MORE battery to turn the connection on and off all the time manually, than to just let it sit idle.
Also, the N1 is useless without a data connection
i see. then ill just let it open and search for an app that will tell me which app uses the most bandwidth. i only found some that tell me the total usage, not by application...
Hey,
did you notice that you can't hear a livestream over WiFi with the Nexus One?
When the screen goes out, the Stream brakes up.
I tried to Ping the Phone and the Ping is on 100 with screen on and gets timeouts or ping at about 1000 when screen off.
This is a huge problem.
Has anybody noticed this and a chance to fix it?
I'm assuming you have your wifi policy set to Never.
I've also noticed my wifi being a lot slower when turning off my screen. This seems to be to save battery.
Yes, set to never.
Battery saving is koay, but unusable WiFi /Webradio isn't.
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.
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
Sent from my NookColor
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.

This also explains why the wifi doesn't kick out when a music player is playing. I don't have enough posts yet to post a real link :/

Dang, I wish I would have found that app before I made and released my own.
http://www.appbrain.com/app/softlocker-free/otis8.softlocker
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.

Well, I'm the SoftLocker dev...so...I'm listening.
I saw the waketimer option for a timer and liked the idea...perhaps a future update?
I've always had my data on in all my phones.. .I got fed up of the gnote's battery life so I decided to turn it off when I was not using it and God I was surprised, I watched a whole movie and played that train game and I lost only about 15 -20% of my juice.....
so today I turned off my data and WiFi before i went to sleep and when I woke up 6 hours later I had only lost 1%
that has never happened before...
Uploaded with ImageShack.us
wifi has been known to be a great battery hogger on the note, interestingly enough it should be the other way around
as for the data, the phone works extra hard in lower signal areas to boost reception, hence drinking juice
I always disable wifi and data when I'm not using them.
I use the Go Power Master widget to switch between different profiles I have set up for wifi, mobile data, wifi with autosynch and no data.
There are other widgets that do the same thing. Just saves you having to toggle each setting separately.
If I stay connected with wifi, it's not too bad, but if I move out of a wifi area, and leave it on, it seems to drain battery faster (I'm guessing because it keeps rescanning for connections?).
I have somwhere describe this
Any way you will find this solutione better.
Use phoneweaver, you can describe the time, it will stop data at defned time, as well switch on too at your describe time. So if you set data off time just after your time to sleep, N switch on time just b4 your wake up time, you even need not to bother do do it manually
same way this can be triggered by location too, you can switch on/off data/wifi at perticular place.
And there are lot action you can set.
agree to rechlum if you are connected to wi-fi is consume less battery thn you are connected to net with 3G, N keep wifi open with connected to data is draining battery too fast.
could it all mean that I wasted a lot of time trying to reduce my battery consumption with WiFi on?
so far by disabling the unnecessary apps strartups (Autorun Manager) and turning off non-essential syncs I was able to get down to ca. 7mA (Battery Monitor Widget estimates) in standby mode, BUT only when WiFi is off.
When it's on, the power consumption stays at ca. 60mA in standby mode, which is something I cannot comprehed - using CyanogenMod on my previous device I was able to stay below 15mA regardless of WiFi state.
Turning off data is pretty stupid. I don`t about you but my phone is actively working in the background.

If I know I'm not going to be looking at my phone for a while, it's not much use wasting battery having wifi or 3G turned on.
I'm a teacher, so I often have 3-4 hour blocks of time that I won't touch my phone.
I just turn wifi or data back on when I'm ready and my updates still come through when I'm ready to view them. Any updates that might have come through if I had left data enabled, I wouldn't have seen any earlier...
If I'm watching a movie I'll often switch off data because I know I won't be looking at my phone for 2 hours.
I don't see how conserving the battery is "stupid".
One could argue that leaving data enabled when you aren't in a position to use it is "stupid"...
Just out of curiosity, is there some pre-made application that allows me to turn data and wifi off after 5-10 minutes after then screen has been turned off and then turn both back on when the screen is turned on? Or should I just code it myself?

there's an option in Settings / WiFi Settings / Menu key to turn WiFi off when screen is off,
besides that there was one to do exactly what you need, but cannot remeber it's name, if you don't find anything satisfactory then try Lama - it has quite a large range of location-based triggers
Leaving wifi on when you're not using is awful. It completely prevents the phone from going to deep sleep.
I get awesome battery life simply by leaving wifi on only when the screen is on. My battery ranges from 18 hours to 1 day and 23 hours, depending on my use (temple run )

Greenpower will do exactly that. You can set it up so it turns off wifi and 3G/data after a set amount of time after turning off the screen and turn it back on when the screen is turned on. You can have it sync once every n minutes/hours so you still get Whatsapp, emails and other stuff without having to turn on the screen.
It's working like a charm for me, before I used to lose 15 to 20% every night, now with the same usage I've only lost 30% in 67 hours.

Everybody has different needs. If you need all this and to be aware of what i going on in your no-doubt busy social life, then you can do this.
On the other hand, it is utterly useless if you are not going to pick up the phone and see what the weather is (instead of looking out the window) and who is doing what on Facebook (or writing things in Facebook instead of actually doing things) as soon as it beeps at you. In those situations, turning of data will save battery with no loss of information.
Personally I love a 'pull' digital life, rather than a 'push' one. I have far too much to be getting on with to be constantly hassled.
Of course, in actually writing this, I am proving myself completely wrong, but what the hey?
I only care about my Google+ account and my e-mails, everything else matters only when I personally decide to check it. As such I've set my phone to turn data back on every 30 minutes, sync e-mails and Google+, and then turn data back off again.
I use Timeriffic (free from Market/Play) to disable Wifi/Data etc based on time of day.
I don't really care about emails when I'm sleeping!
A must have application IMO.
