Having a big problem with Wi-Fi sleep policy. Everytime my phone goes to sleep wifi discounts after a period of time, so I go into the wifi settings and change it to never sleep but the setting never stays it goes right back back to sleep in 15 mins. This problem just started to happen last week.

Hi all,
I just got a Droid 2 Global today and I notice if you leave it alone for a while (which is hard to do with a new phone) the WiFi will turn itself off. The first thing I do with new Android phones is turn the WiFi Sleep Policy to "Never". And that is what I did today, but it still appears to be sleeping.
When I wake the phone I notice that the WiFi is off (Both up in the notification bar and the widget is dark) and the 3G is off as well. The only that is showing is bars. In about 5 seconds the WiFi will turn back on and connect.
Now this only happens if I don't play with the phone for a while. Turning the screen off and back on the WiFi will be on like normal.
As this annoys me that it is doing it, it is the 3G is off at this time as well. Which means the phone isn't getting any data during the period that it is off. Which isn't good since I rely on Google Voice for all of my texting, which won't come in unless there is a internet connection.
Any help on this will be great,
Thanks
I did find out what was going wrong last night. In Settings>Battery Manager>Battery Mode it was set to Nighttime saver. That would have been bad because I work 3rd shift and I'm up and using this mainly at night.
I have trouble downloading large files using this ROM since when my screen turns off, WIFI is also disabled. How can I change it. I've been looking in the settings but to no avail.
Edit: Found it...you have to click menu when in the WIFI Settings, then choose advanced.
Edit2: Wifi is disabled when screen is turn off even if the Wifi sleep policy is changed to Never.
Any ideas?
then that is some kind of bug. because setting wifi sleep policy to never should behave as such.
related note, setting wifi sleep to never greatly increases batteyr life, as said thru the forums, because back on 3g the data kills your battery much faster. so allowing wifi to stay on makes a huge improvement on battery.
for example if you leave wifi on overnight, you might lose 5% total. but if it switches back to 3g overnight, you might lose 20%.
is this bug confirmed?
me too have same problem with SuperAosp (i will test with other rom....)
My WiFI Sleep Policy is set to default (After 15 min) however the WiFi is always on. The icon is there when I turn my screen on. Checked the battery usage graph also, and WiFi is always on (as long as I don't turn if off manually).
I have a stock ROM, the latest European stock ROM.
Is this a bug? What does 'After 15 min' actually mean?
I believe it means the wifi will turn off 15 minutes after the screen goes off, and then back on with screen on.
I thought so too, but mine isn't doint that.

I know there was a recommendation to set "Never" as the sleep policy. I can't find that post unfortunately. I know on my Desire with CM7 it resulted in better battery life, counter intuitive but......
I know. I've had it set to Never on my Desire. But now I'm seeing longer standby with the current setting (After 15 min) on my Sensation compared to the Desire. Although I suspect it isn't working and it's actually never turning off.

Lol, same upgrade here. TBH I've left it at Never and not tried the other policies.
I use WiFi when at home, I'm on a 3G data plan ( I'm guessing WiFi sleeping means I wouldn't get updated Gmail. Or does it revert back to 3G ?
WiFi sleeping means going back to 3G, yes.

Thanks, might just try it and see.
Does anyone think that instead of going to sleep after 15 minutes of the screen being turned off (regardless of whether there are background apps that have active internet connections), the WiFi actually starts sleeping after 15 minutes of idle time? I think this would be a better efficiency algorithm, so, as long as you have apps that constantly use the internet, keep WiFi connected, but when no apps are doing auto-sync or any background data, only turn on WiFi when manually using the apps..
Applications can be programmed to call for a WiFi lock. If any active application does so, WiFi won't shut off when the phone is asleep.

I remember that old tips thread. It was set your wifi sleep policy to never. Install spare parts+ or pro and set end button behaviour to sleep. And something to do with Market app. Settings->notifications-> uncheck the box. For some reason market notifications were not allowing your phone to go to sleep properly or some garbage like that. Its worth a shot.
EDIT: Still unsolved - see post nr3
"keep wifi on during sleep" is set to "only when plugged in" - it worked like a charm in lollipop (it switched off wifi after some seconds of disactivity), it doesn't now.
EDIT: In lollipop after some seconds of inactivity wifi was turned off, that was proper behavior I guess... It is not working in Marshmallow.
1. GSAM Battery monitor seems to have problems with showing WiFi activity on Marshmallow (shows "on" when switch is turned on, but it's inactive). I used build-in Marshmallow graph instead (settings > battery) and that showed me, that WiFi is indeed being turned off during sleep.
2. In my Lollipop WiFi became inactive just seconds after screen turned off. I expected the same behavior from Marshmallow, but it is different. It seems, that now wifi is turned off after 20 minutes of inactivity (checked few times).
Am I right about deactivation timer in Lollipop / Marshmallow? I guess It's much better now, since in Lollipop I sometimes had to keep screen active in order to install all upgrades, etc. But for me 5-10 minuted would be perfect instead of 20 minutes. Any way to change that?
After some weeks I have to say, that problem is unsolved. I can't repeat the situation when wifi was turned off when phone went to sleep.
I tried safe mode - the same effect, wifi is on when screen is off. Even after I am going back home with phone in my pocket it automatically connects to the router (with screen turned off, phone should sleep)
Does anyone have similar problem?
Bump - more info.
When I turn off Wifi my phone uses 1% or less battery during night. With Wifi turned on it uses 5-10%. If it worked like it should and turned off wifi when screen is off it would use the same amount of battery life as when wifi is off.
Could anyone at least confirm, that I am the only one that has that problem? Your marshmallow Nexus 5's are working as expected?
The wifi icon disappears after few minutes of screen being off after locking. I did set wifi to be on during sleep. Does anyone else have that issue ? I have a SIP client installed on my phone and need wifi all the time so that is a pain.
Mine does the same thing. I think it might be because I have the *intelligent power saving* checked in "power management" in settings. I think the phone disables data every so often to preserve the battery. Haven't tested my theory by un-checking, but I remember this happening on my Blu studio energy.
I have intelligent power disabled.
I think I am getting this on my phone. Sometimes on wakeup it forgets it is connected to Wifi and apps and chrome won't update. I usually just turn airplane mode on/off to fix it. Still, it is annoying. Doesn't seem to happen with LTE, at least.
