[Q] Shorten wifi sleep timeout after screen off (Solved)

In the wifi sleep policy, it is possible to set wifi to sleep after screen off. However wifi does not sleep immediately but 15 minutes after screen off. I would like wifi to sleep earlier, say 5 minutes after screen off.
I searched around and found an app capable of doing this. But it is for samsung phones and doesn't work for defy. Does anyone know if and how it can be set manually?

Juicedefender. That is the exact app to use.

I tried Juice Defender. There are options to disable wifi based on connection existence, preset time, data flow etc, but there is no option to set the how long after screen off wifi would sleep.

Here you go, this should do what you want: http://forum.xda-developers.com/showthread.php?t=774507
Good luck

Hmm I actually set my wifi to never turn off automatically. For instance yesterday I made a phonecall with Skype. My mobile connection is too slow for that so I switched the wifi on. During the phonecall I had the screen turned off but of course the wifi needed to stay on.
I have a widgetsoid widget on my homescreen to enable/disable the wifi. Don't like it when things go automatic and it's just as easy when you need wifi only once in a while.

Since i changed my ROM, my wifi actually goes to sleep after 15 minutes and I don't want it to turn off.
How do you set your wifi to never turn off automatically?

Thanks! Unfortunately moto doesn't have the settings.db file. I tried putting the mentioned key "wifi_idle_ms" in several other files but no effect.
Edit:
Stupid me. I find the location of settings.db and it works perfectly now
For information, the location of defy's settings.db is:
/data/data/com.android.providers.settings/databases/settings.db

In the wifi settings screen, press the menu button to get the advanced options.

Thanks guys; I can now listen to TuneIn radio as long as I want (or my battery allows me to).

If you intend to save battery, maybe you should consider leave "wireless policy" to "never sleep".
It might sound senseless but there are a lot of people reporting substantial battery savings with this, including me, i noticed at least +20 hours in battery life only with this little thing. Charts drawn with Battery Monitor showed the same consumption, Wireless OFF. vs Wireless policy to never sleep. And the most expensive was policy of sleep when screen turned off.

That's probably the case for 3g. But I'm using 2g and find 2g uses less battery than wifi in standby mode (with some background data sync).

[Q] Wifi Sleep Policy of Off Screen on SUperAOSP ROM

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....)

ICS Wifi stays on while on sleep

Hi guy, my wifi won't turn off when my Xoom is on sleep. I have set the settings of 'keep wifi on during sleep' both to 'NEVER' and 'ONLY WHEN PLUGGED' but nothing happens. Wifi stays on and keeps draining my battery life. I am running rooted with the latest version of nightly 62 and I've been having this issue since 55. I have reinstalled, flashed, factory reset, wiped my Xoom.
Is anyone else having this issue? What should I do?

From my experience, wifi stays on for a little while longer after device sleeps. However, some apps in background may trigger wifi back on again. So I turn off wifi when i go to bed. Actually i notice wifi itself will not drain much battery, 1-2% for 10hr. It's the host apps sucking the juice.
I am not an expert though.

OK i've also checked it out and as you said wifi turns off after some time. My main problem now is that my battery life won't last more than 3-4 hours on wifi.
I have posted my battery stats with use of web browsing and watching pictures on gallery...

What do you mean "no more than 3-4 hours"? In your battery chart, you can get more than that even starting from 75% battery.

What I wanted to say is that I think my battery won't last more than 4 hours with wifi on and some serious usage.. from my stats as I can see I've been using it 5 hours but I only had screen on and browsing the web. I think there will be a huge difference if I am watching a movie or playing a game.. I don't have the time to check it now but I will post my results in some days..
According to my previous battery graph do you see any problem or something less from what your Xoom battery holds? Does this battery drain seems normal to you?

I think you'll find it will stay on for about 15 minutes. There is some setting in a system database (using a sqlite editor) that can be changed to bring this down. I doubt Wifi is what's draining your battery. Are you synching email via activesync or running other stuff in the background?

I am only using my yahoo mail from the EMail app. I don't know if it uses activesync. I have set it to check emails every 30minutes.

wifi not turning off
Edit: I found the wifi sleep option in ICS. Google sure did a great job of hiding it. See attached picture for anyone else having wifi staying on during sleep issues.

So there are three options
Keep WiFi on during sleep
1) Always
2) Only when plugged in
3) Never
What option to set if i want Wifi to turn of after some time of when phone sleeps. Previously i had set the option to 15 minutes but that option is not available in ICS and i m having a hard time understanding how these options work on my sensation.
Can anyone explain what each of these options do ?

My guess:
1) Always: WIFI always on no matter awake or asleep
2) Only when plugged in: WIFI always on only when plugged to power
3) Never: WIFI will be off if asleep (my current setting)

That was it

Bear in mind that (irritatingly) applications can seemingly change this setting.

For an app to change wifi sleep policy, it needs the WRITE_SETTINGS permission.

[Q] Weird Wi-Fi Usage Pattern with Using ART Runtime

Hi guys,
Did anyone else notice this strange result after switching to ART compiler? When I check battery consumption in Settings -> Battery, Wi-Fi power seems to be always on for the whole duration of use. Even though I made sure it has been turned off as I left home for work, Wi-Fi is showing up as running since I've unplugged the phone. It's quite a consistent issue. Reverting back to Dalvik would allow Android to record correct Wi-Fi power pattern so I'm guessing this is probably associated to ART. I'm sure I can't be the only one experiencing this issue? Please someone provide a bit of insight.
I'm using completely stock, unrooted, KitKat 4.4.2.
Other than that I'm very happy with ART, not much of a speed boost considering Nexus 5 is already blazing fast, but I can definitely feel the extra snappiness when switching between apps Weirdly, with the Wi-Fi issue, battery life seems to be just about the same (or even better). By the way, I don't believe Wi-Fi is actually on, it's probably just a recording or reporting bug.
Cheers everyone! Please let the conversations flow!

I think you have the "Scanning always available" setting turned on ( Settings>WiFi>Advanced>Scanning always available).
It's a feature that lets the phone scan for WiFi networks even when you turn it off, just for location purposes. So, even if you turn it off, technically it's still on, that's why it always shows in battery stats.
It has nothing to do with ART, I'm using it and it's great.

Hi raul90, thanks for the reply! I will try disabling the feature, but I've always had the feature enabled, and battery stats reports correct power pattern when I switch back to Dalvik. The only variable is the runtime, no more.

Data always stop after a while when screen off

Hello
It's really annoying, everytime I try to download a big file, the screen goes off and cut the network.
I checked a lot on the web, but everybody is talking of wifi. My problem is for 4g/LTE.
Even setting maximum limit for screen off (10 minutes), and touch the screen every 10 minutes. it's endind with a download aborted....
Anybody got any solution?
Thanks

Connect to charger and change settings to never sleeps.

Settings > Developer Options > Keep Mobile Data turned on
If that doesn't work, enable the setting "Stay Awake" at the top, then connect your charger while you download on 4G, the screen will never turn off while charging that way

The 1st solution you gave is not exactly that. It is : keep mobile data on when wifi is active.
On the other hand, the stay awake is charge is a good solution.
Not that I think it's normal to use this kind of thing of trick , but it's working.
Ps: data saver is always off

Yea more of a workaround than a solution but if it works it works
With the Mobile Data always on, if you have WiFi set to stay on while sleeping, then mobile data might also stay on with WiFi, that was my thinking
EDIT -
Check that Google Play Services > Data Usage does not have "Restrict Background Data" enabled too, that can cause this problem
