Hi all,
I'm wondering what is better option in the Sleep Policy for battery life when you have no access to a WiFi network? Sure, sure, turning off the WiFi will get you better results when you don't have access to WiFi but the location features you get from using WiFi.
At work I have no access to the WiFi network which isn't connected to the net anyways. But it works great for getting precise location information when inside the building.
I tried keeping it on "Never" but wow does that kill my battery.
Does putting it on "Never when plugged in" or "After 15 minutes" keep it from searching for a WiFi signal all the darn time which is what is killing my battery.
From what I have seen since I changed it to "Never when plugged in" half way threw the shift it doesn't seem to draw as much power. But I did check my Google Latitude history and it seems to be pulling my location from WiFi instead of the cell tower. All but a few times did it get the location from WiFi instead of the cell tower. So that has me wondering is it still looking for WiFi or just turning it on when getting a location request.
Any help would be appreciated.
Thanks
I am using a stock HTC Droid Incredible.
I would like to have it where when the screen went off the wifi went off, but that could be a problem if the screen keeps going on and off from texts or whatever else. Would probably use more battery starting wifi over and over again.

HI Guys,
After having moved from my HTC legend to an HTC trophy 7 and getting used to all the interesting little fiddly bits of WP7 I was finally happy (Im mainly talking about the windows live mail contact sync issue).
All contacts finally fixed after a some time sorting them all and adding the phone numbers etc.
Anyway long story short the does not seem to be a way to make the WIFI stay on when the phone sleeps meaning that my preciously short 3g data will be used (Vodafone skimping and giving us only 500mb).
Has any one come up with a way to force the WIFI to stay on ala android sleep policy?
Cheers guys!
Your 3g would only be used if you are constantly downloading emails. Everything is push on WP7 so there wont be apps pulling data other than email. I wouldn't worry about it. WP7 is not android.
If I disable 3G while sleeping on WiFi is there ever a chance WiFi won't wake up for the push/pull of email or am I worrying about nothing?
Keep it connected to a charger or your PC and the wifi will stay ON.
Thanks for the replies guys,
Hopefully data usage will be better than android but I would sill like to be able to turn wifi on all the time is I needed to. In the mean time all email set to as arrives so should cut down on usage a bit.
Lets see what this next update brings
cheers

As the other chap said, plug your phone into power and wifi will not turn off. I nall honesty, wanting the wifi to remain on while the phone is on battery power is a bit daft because it wouldn't last longer than a couple of hours.
Thanks again guys,
Granted leaving the wifi on all the time may drain the batt faster but my HTC legend managed like this with no issues as Android turns off 3g when WIFI is on saving some power. I think we should at least be able to change the WIFI sleep profile like android - 5m, 15m, never etc

I assume you mean that Android turns off 3g when Wifi is *CONNECTED*. I leave my Wifi switched on all the time and what happens is when the phone switches off, it disconnects, but the wifi setting remains *ON*.
Leaving it on is good because when I get home it connects to my Wifi network automatically but while out and about the phone doesn't keep trying to connect, which would drain the battery a lot.
So yeah, make the distinction between Wifi being "ON" and "CONNECTED".
This issue has happend 2 times. It used my 3G data over 90MB for APP downloading!
As you know, the phone won't allow you to download a big APP without wifi or pc connection by design.
Yesterday I downloaded the trial version of Need for Speed(about 127MB) from marketplace and turned on WIFI before that. I just checked the detailed list of my 3G usage yesterday. In that time it downloaded 90MB+ from 3G network in 20 minutes.
I guess the phone turned off the wifi in sleep mode and continue downloading the APP through 3G.
It should be a bug!
Yes, it is a known issue that WP7 turns off wi-fi when phone goes into sleep. To work around this issue, you need to keep the phone plugged in.
Modern wi-fi chips in phones drain less battery juice when you leave it on all the time than constantly off-on-off. Also, it does not necessary use more battery downloading via wi-fi than 3G. I guess MS didn't get that notice when implementing WP7
We can only hope this is addressed in upcoming NoDo update.
Pretty sure this feature isn't designed like this to save battery while connected to a wifi network, I'm sure it's implemented with this design to save battery while you AREN'T in range of one of your networks, rather than having the wireless chip constantly poll for networks...
As someone else said, just plug your phone into the power outlet and wifi will always stay on.
Ok, I have seen this on 2.3.5 builds of CM7, Deck's ROM and OMFGB. What is going on with wifi on 2.3.5? It's causing some kind of wakelock apparently. Look at the right hand side of the battery graph and compare the "awake" to "wifi" time. I had my wifi to sleep when the screen turns off, so it went away when wifi was turned off. But then if I connect to wifi again with the screen off, it causes wakelock. Is this a known issue? I have tried googling and can't find anything about this. Surely I can't be the only one.
On Sense roms I can leave my wifi sleep policy as "never" and it doesn't cause any issues.
I'm using the CM7 nightly build 180 (2.3.5). I'm using Tiamat Kernel SBC. My WIFI sleep policy is set to never. It's been unplugged for about 8 hrs 45 minutes and connected to my WIFI. It's been on standby for the most part and it's at 99%.
WiFi totally unrealiable on the AT&T Atrix 2 (MB865)

I too am seeing all sorts of issues with WiFi on my Atrix2 (MB865) which is also running Android 2.3.5. As a matter of fact, I have TWO of these, because my wife got one also, and it has the same problems. To be specific, both phones will drop 128Kbps streams and fall back to 24Kbps, if the alternate slower speed is offered. This constant dropping of audio stream is the most annoying problem, but the phone also will spontaneously disable WiFi. After manually re-enabling, it can take up to a minute to reconnect to the AP (the happens at home and at work).
When connected, a speed test might show something like ~100Kbps down. But disabling and reconnecting a few times will help get it back to a good ~20Mbps down again. Sometimes when connected ad showing a FULL STRENGTH WiFi status icon, I am still not able to get any data whatsoever, just as if the WiFi is not even enabled. Examining this with WiFi Analyzer shows that it detects no AP's whatsoever, even while the status icon shows a FULL STRENGTH connection. Again, disabling/enabling can correct this issue.
Just to prove it's not my home AP, I have an old HTC Hero running a CM7 nightly build from 9/1/11 kernel 2.6.29-6 (which is also Android 2.3.5).
My old HTC Hero connects quickly/flawlessly and holds a constants steady 128Kbps stream all day without fail.
Why can't these carriers (AT&T in this case) put out a reliable Android build. I can't help it, but my paranoid mind makes me think it could be purposefully done to force customers to use precious bytes form their costly data plans. They certainly would have no incentives to make WiFi work efficiently.
Anybody got an ETA on CM7 for this phone?

KenB
I See my wifi has used 30% of my battery but ive been on 3G all day, does it drain the battery searching for networks?
It does use some power when searching for networks. There is probably an APP or settings that you can change to set the Freq of checks maybe. Or you can just turn of the Wifi radio when you know your not going to use it.

Yes it uses a lot of power if its regularly searching for networks. Especially if you're moving around and seeing dozens of WiFi spots. Just turn off WiFi when not in use, simple as that.
A lot of custom ROMs have less aggressive Wifi seeking intervals. You can usually set it manually with ease too. Lots of apps out there if you don't want to do it manually.
All that was said is true, but still I find that 30% usage for Wifi just for searching nearby networks is a little too much...
Although I haven't got anything to compare with, I always turn wifi off if I'm not using it during long periods.
Regards
I turn wifi off when it is not needed and battery life goes from one to two days.

I've been using Tasker to turn wifi on at home/work and off when I'm elsewhere. It's using cell towers to determine location, so hopefully it won't impact the battery much.
I leave wifi on 24/7, today it has used 2% of the 60% battery i've used.
I travel through london so I assume it is constantly finding new wifi signals.

Y5 Battery Saver .. on the market, free. Turns on/off Wifi based on known networks and cells in the area of the AP.

I leave wifi on all the time as well, and I also only have used 2% of the 70-80% battery I used up already.
Try going into wifi settings, then advanced wifi settings, then turn off the new wifi network available notification option.
This increased my battery life slightly.

Y5 - Battery Saver helps out tremendously! I barely ever use more than 2% when home all day...although that may be a bug but I started a thread for that already.

That 30% displayed can be deceptive since it's based on the amount of battery discharged and not entire battery capacity.
Well wifi, when on is looking to connect to known networks. If the signal is weak it will disconnect and connect to another network near by if there is that has better signal. This process does use some battery. The biggest drain will occur when you are actively using wifi, that is when you download or upload. So the best way to save battery, is to close wifi when not needed. If however you want wifi you can set it to never sleep. This way even if the screen goes off wifi will be connected and your device wont use the 3G which is way more power hungry.
hey guys maybe u can help me out
so according to GSAM battery Monitor
my WIFI is shown as active the whole day but my WIFI has been off the whole day. it has accounted for 7.8% battery drain even tho its off in the settings
even the HTC battery manager History shows a solid green bar all the way thru
im rooted with s-off and running android revolutionrom, this issue was occuring before my root and flash of the ROM, i was hoping that i rooted and flashed the ROM this problem will go away.
what do i do, you can see my wifi is off cuz the icon doesnt show in the status bar and i have ensured i have set it to off.
There is an option to Enable Scanning Even When WiFi Is Off. It enabled location services to use nearby wireless networks to triangulate you, but it leaves the wifi antenna active, even with WiFi switched off.
You can find this option under Advanced WiFi Settings.
awesome thanks
