Wifi Standby Policy - Nexus One Q&A, Help & Troubleshooting

I was playing around with the Wi-Fi sleep policy settings and I am little bit confused how it really works.
The default setting is something like: "turn off wifi when screen is turned off".
So as I understand it it should disable wifi when the screen is turned off.
However when I checked my device list at my router it seemed that my n1 was still connected through wif, even after the screen was turned off. Only after 5-10 minutes wifi was really disconnected (when I turned on the screen again the wifi symbol in the top bar appeared after some seconds). I read somewhere that there is a difference between disabling wifi and disconnecting wifi?
BTW. the wifi sleep policy is supposed to save battery because it is said that 3G in idle mode requires less power than a wifi connection, but I read that with the nexus one the opposite is true. so what's the truth?

It's normal for the wifi to disconnect after several minutes of inactivity once the screen turns off. As for your very last question, I don't know... but I imagine that idle 3G is less power intensive than active wifi, otherwise it wouldn't be the default option...

[Q] CyanogenMod Wi-Fi Problem

Hi,
I have flashed my N1 with CM6.1.1 around 2 weeks ago. I'm really satisfied with this ROM.
However, I have noticed my Wi-Fi has gone a little bit weird after flashing CM. Regardless of the Wi-Fi sleep policy setting, my N1 won't turn off the Wi-Fi after it's locked. When I unlock my N1, I can watch the wi-fi icon disappear and then re-appear after a few seconds.
Now I have to manually turn off the Wi-Fi before locking my N1 to conserve the battery. Does anyone know how to get rid of this bug?
Thanks.
i will give you one tip which is its better to leave wifi ON when your phone goes to sleep because it's much better for battery life. if you let wifi turn off during sleep, the phone switches to 3g data which drains far more battery than leaving it on wifi.
now about the disconnect issue, i'm not quite sure what you're seeing. i have a problem with cyanogen 6 where my wifi disconnects for about 3 seconds, and this happens about every 10 minutes or so. its very annoying. but when my phone goes to sleep, i wake it up and still see wifi connected. so no issues there for me.
Wildmonk has some kernel just to address the WiFi issues.
I suggest WM kernel with CM ROM anyway
The problem occurs randomly. Sometimes my phone "knows" it should turn the wi-fi off when it's locked. But most of the time it doesn't...
I think I will live with it.
Anyway. Thanks for the reply.
My WiFi still disconnects every few minutes, then re connects again. It drives me nuts. Cyanogen 6.0
to momomok,
I think you have misunderstood the word "sleep" for Wifi, here sleep means when you are not using your phone the Wifi will turn off temporarily instead of infinitely. It's more like a nap. As you unlock the phone, Wifi will get awake. That's why you will see it re-appear after a few seconds.

Smart Actions and Wifi

Anyone have any issues with Smart Actions and Wifi? I am running ICS .232. Recently i've been noticing my battery draining and my system is telling me that my Wifi has been on for 7 hours. I check the Wifi settings and it's set to off. I turned it on and off to be safe. The only thing I can think of was Smart actions not shutting it off as it states it was. I just removed the rule to turn wifi off and on depending on my location. It's suppose to turn off wifi while at work to conserve battery but it seems to be draining my battery instead. I just checked it now and the solid bar is short at the end indicating it is no longer on. Wondering if anyone has the same issue? BTW I've been at work for the past 8 hours so Wifi should have been off. Location is flaky in my area even with GPS as there is a dead spot close by. I work out in the country..

[Q] Wifi never goes off in sleep mode

I have a strange problem. I set the 'Keep Wi-Fi on during sleep" to "Only when plugged in" but I see that Wi-Fi stays always on, also during sleep. In addition I noticed that the largest battery consumer is Android OS. Any ideas what's wrong?

Under Wifi Advanced Settings, you probably have the option for "Scanning always available" enabled. This keeps wifi available for location services, and makes it look like it's always on to the power monitor.
No. It is disabled

Your battery usage doesn't look off. Android OS is almost always the biggest battery consumer on mine unless I'm using the phone heavily. wifi is typically 3-4.
I easily get through a day on a single charge. Usually I've got between 20-40% left at night depending on usage.
As for wifi I don't know. Perhaps there is another app keeping it on. I would try turning all location services off and see if that changes anything.
I'm curious why you'd want wifi off. generally it will default to the mobile signal which will use a lot more power. only reason to turn wifi off is if you don't have access to it.

WiFi remains active even after I disabled (battery)

Guys, tonight I decided to switch off mobile data and WiFi when I went to sleep. Now noon, when the battery was almost over I decided to analyze some attention to battery depletion statistics and realized that even turning off the WiFi it continued to appear that spent the whole night on. Also, see that shortly after I slept network operator turned yellow. How to explain? My carrier has the much more stable network overnight just by reduced use and the absence of network overload.
He had the 3g network enabled, less mobile data.
It happens to me too. I guess it's only a visual issue, I dont think wifi is draining battery life.
Due to Wi-Fi scanning always available. Its actually keeping the Wi-Fi on if that option is chosen in Wi-Fi advanced options. Turn that off and you'll see that your Wi-Fi actually shuts off.

Mobile data turns off when I turn off WiFi!

Hi,
Anyone else having this issue with their note 9? So when I have WiFi turned on overnight and when I wake up and I go out of WiFi range (WiFi is turned off), I realize my mobile data is turned off. I would have to go under settings > connections > data usage to turn mobile data back on. I'm not sure what the cause is and it seems to only happen after long WiFi usage (like overnight). The weird thing is it doesn't always happen. I'm not sure if it is a battery saving things or something is turning it off. Please help! Thanks
