Motorola Droid X :: WiFi Sleep Policy - Optimal Setting?
Jul 22, 2010
If you go to Settings->Wireless and Networks -> Wifi Settings and then hit the Menu button (the one with for squares on the bottom left) and go to advanced there is an option for Wi-fi Sleep Policy. It looks like the default is to turn off wi-fi and switch to mobile data when the screen turns off? Is this the optimal setting? Wouldn't you want it to never turn off (assuming you are in range of wifi)? That way any alerts etc. are all handled over wifi instead of data?

I'm confused about the WifI Sleep Policy. What does it mean for wifi to sleep, does it mean to stop searching? Mine is currently set to "when screen turns off", but I've seen others suggest that it be set to "never".

What is your take on the WiFi sleep policy. I do like the fact that Wi-Fi can remain on all the time, but will it be a drain on my battery? Is it better to keep the Wi-Fi to sleep on screen shut off? I am near a Wi-Fi connection for most of the day and always at home.

I am trying to write the system setting using:
Settings.System.putInt(getApplicationContext().getContentResolver(), Settings.System.WIFI_SLEEP_POLICY, Settings.System.WIFI_SLEEP_POLICY_NEVER_WHILE_PLUGGED);
But it force closes my application. Any Idea? My has user following permissions:
<uses-permission android:name="android.permission.WRITE_SETTING"/>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/

After noticing my battery was draining quickly, and then after reading this thread, I installed Android System Info to see what was draining my battery so fast. I notice that whenever I would turn on WiFi, the phone will never go to sleep , regardless of what I set the WiFi sleep policy to. After turning off WiFi, the battery still drains heavily.
The WiFi will shut off after 15mins (if you set it to "When screen turns off" or "never when plugged in"). However it seems to keep the CPU on causing it to drain down the battery.
It would seem that whenever WiFi is enabled, the Android system process creates a partial wakelock that does not go away even if you turn off WiFi. The only way to resolve this is by powering off or rebooting the phone.
You can verify this in Android System Info by going into Battery-History-Other Usage-Partial Wake usage to see how much time the "Android System" process holding a partial wake.
I even did a factory reset on the device; and it is still happening so it doesn't appear to be any app that caused the issue. As I said, it works fine as long as I don't enable WiFi.
I already know of two users having this issue, but I'm wondering if folks having battery problems are going through this as well. Is anyone else having similar issues after using WiFi? I'm hoping someone will be able to identify what exactly is putting the wakelock on and we'll be able to find a fix for it. Other than not using WiFi at all or rebooting the phone after using Wifi.

back with 2.1 there was the issue with GPS, and once it was activated not allowing the phone to "sleep." You could see the results of this in the "Battery History" screen that Spare Parts would give you.First of all this does not seem to be fixed with 2.2 unless im missing something in my settings, and actually it seems to have gotten worse.Even when i change my WiFi Sleep Policy to turn off when "screen is off" it seems as though the phone cannot go to sleep, and my Wifi is not turning off as it should.

I know Verizon has a 30 day money back (minus restocking fee) return policy. Does this apply if you get your phone from BB? Do they have their own return policy? If so, is it still 30 days?

I bought the eris almost a month ago so my 30 day return policy is getting close. I like the eris a lot, mostly because of it's size and the senseUI, but a part of me yearns for the larger, sharper display of the moto droid. Now, I've noticed my eris is starting to chug slowly to do things like typing, changing apps and I'm not sure if it's just because I'm running a bunch of stuff at once or what, but its making me feel like I'd rather have the powerful processor of the droid as well.But, what if I get the droid and decide that I liked the eris better. Will I be stuck with the droid or can I return it and go back to the eris? I guess what I'm really looking for is an explanation of verizon's return policy and perhaps some feedback from those of you who switched from eris to droid.

I have 70 tablets and i'm trying to set up a quickway to make them all the same, i have most of it sorted. All i need now is to set sleep display time to 10 mins and change the wallpaper to company logod one.
So far my approach has been, set one up how i want it, use adb to copy files to computer, connect next tablet and push those settings.
1/ where is the sleep timer setting stored?
2/ how do i set a wallpaper using adb?

I'm seeing that some users are downloading data via my application and their connection is dropped because the WiFi is going to sleep. Could I somehow take control over WiFi to keep it alive and once I'm done I return it to it's default state?

I've heard everyone mention that setting wifi to never sleep has helped battery life but I can't figure out where to find the controls for that policy.

i have just got a new htc desire and love it have read this http://androidforums.com/htc-desire/59664-htc-desire-tips-tricks.html which is very good but have a few qu's:
1) do background apps use any/much power?
2) does wi-fi switch itself off if it is not needed or when there is no connection available? (i have wi-fi at home and unlimited internet so if i leave wi-fi on when i'm at home, after i leave will it switch itself off?)
3) is there an app for sleep that monitors your sleep using the inbuilt sensor so that it wakes you up when you are ready with a set time period (for example 7:30-8:00) and monitors how much you move about at night?

I have a smartq t20 tablet (great cheap tablet!) running ICS, my question is, when I leave wifi on all the time, what happens when the tablet goes to sleep (not awake according to the battery details)?I can leave a download running and it would continue when the screen is off, does this mean my tablet is never going into deep sleep? Or is that unrelated?
I know the wifi itself drains more battery when left on even if it isn't being utilized but I was wondering about the CPU side of it.

I downloaded Locale recently and it looks like a good app. I have set it to turn on my Wifi shortly before I get up in the morning to allow it to download some files (Guardian App and hopefully some podcasts). I've set Guardian to only download the newspaper via Wifi. For some reason Locale doesn't seem to be able to switch the Wifi on unless I awake the phone from sleep. I've been into the Wifi sleep policy Setting menu on the Hero and set it to never. Any ideas why it's not working?

Is there an app that can turn off my wifi whenever I put my phone to sleep? To conserve battery, I always have to turn off my wifi before I turn it off, and turn it back on when I unlock it. After a few days of this, it gets pretty annoying. I'm used to the iPod touch where when you sleep it, the wifi automatically turns off to save battery,and when you unlock it, and turns it back on. It would really save me the time.
Also I noticed this Wifi sleep policy thing. I don't really understand, can someone elaborate or explain more. Is it that when your not using your wifi for +15 min, it automatically turns off? Do you turn it on manually, or does it do it auto when you starting using wifi programs like browser.

I have a service which polls a server at certain intervals. I use an AlarmManager and a BroadcastReceiver to start the service. My problem is that after a certain duration, even though the WiFi is still enabled, but for some reason, my application can't contact the server. I get an "Unreachable network" error. Note that I've already acquired a partial wake lock as well as a wifilock. Here's my code for the BroadcastReceiver.
public class ServiceAlarmBroadcastReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
WakeLock wakeLock = null; WifiLock wifiLock = null;
try { PowerManager pm = (PowerManager) context .getSystemService(Context.POWER_SERVICE);
// acquire a WakeLock to keep the CPU running
wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakeLock");
if(!wakeLock.isHeld()){ wakeLock.acquire();
} Log.i("ServiceAlarmBroadcastReceiver", "WakeLock acquired!");
WifiManager wm = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
wifiLock = wm.createWifiLock(WifiManager.WIFI_MODE_FULL , "MyWifiLock");
if(!wifiLock.isHeld()){ wifiLock.acquire();
} Log.i("ServiceAlarmBroadcastReceiver", "WifiLock acquired!");
context.startService(new Intent(context, ThePollerService.class));
} finally { // release the WakeLock to allow CPU to sleep
if (wakeLock != null) { if (wakeLock.isHeld()) {
wakeLock.release(); Log.i("ServiceAlarmBroadcastReceiver", "WakeLock released!");
} } // release the WifiLock if (wifiLock != null) { if (wifiLock.isHeld()) { wifiLock.release();
Log.i("ServiceAlarmBroadcastReceiver", "WiFi Lock released!"); } } } } }

My android 4.1.2 really turns off the wifi when in sleep mode. I see it in the battery monitor.
But after I formated the cellphone, It started with the bug of not turning off the wi-fi in the sleep mode, even when set to do it Maybe some app that I installed before has changed some internal settings!
Before, my battery was lasting almost 4 days, I not use it too much, but now it lasts 2 days only... and I have sure that it's because of the wi-fi bug.

I am not rooted and I don't have 2.2. Have wifi, bluetooth, etc off. I have spare parts. I was losing 20-30% battery overnight with my phone fully charged at 100% so went into spare parts in battery history and it said the phone was running 100% for 12 hours. So to test it today I plugged it in, charged it to 100%, unplugged it, killed all tasks (even task manager), shut the screen off and sat it down for 2 hours. When I turned it on it was at 80% and spare parts said runnning 100 and when I click that it says "time spent without sleeping 2hrs (99.99025592487624%)

For some odd reason my phone will not "sleep". The screen just stays on. The only way I can get it to sleep and the screen to lock is to push the power buton on top of the phone. I have the screen set to time out at 1 minute. I have searched and read but no real answers for this phone.

If I hit the power button to shut off the screen, does it sleep immediately? Or is there a time limit? I ask because when my screen is off for a little while, I stop receiving notifications for text and emal, battery is in performance mode.

I am annoyed with the fact that the phone sleeps when on a call. I primarily use it with bluetooth while driving and to end a call i need to unsleep the phone and then I can do so.
Is there an app or setting that will disable the sleep "feature". To me this is one of the most annoying things about this phone.

I apologize if these topics were already covered in previous threads.I wasn't able to find anything related in my searches. Auto-rotation for keyboard when answering a text message received in sleep mode does not work. If I actively send a text when phone is already awake, keyboard rotates with no problem but when I go to reply to a text that I received while phone is in sleep mode, the keyboard does not rotate. Is this the norm?I am also experiencing a delay when the I wake the phone. After unlocking the phone, I used to go straight to my home page, now I get a "loading" message which takes several seconds. Is this due to the number of apps I have loaded? Is it possibly due to number of photo frames I have on my home screen or the complexity of the wallpaper?

I have the dock (now) and I have the Droid set to sleep and lock after two minutes. Great while I have my phone out of the dock but annoying when it is in the dock. I don't see a setting to disable sleep mode while docked.

So I'm currently running the newest rubix build with the leaked version, but I've had this problem with other roms before this. I notice sometimes my phone just wont go to sleep and no matter what I cant figure out why. I dont have any crazy apps or services running in the background and in fact I think my wifi is part of the problem. For example, today I've had the phone off the charger for about 3 hours. I just checked it, and despite my screen only being on for about 30 mins (also no streaming or background data being used that I know of) my phone was running the entire time (100% reading in spare parts). I also noticed my wifi use in battery manager was high so I shut of wifi and of course the phone finally goes to sleep almost immediately after. I can't replicate this problem everytime although I havent fully tried, but I do know I've had a similar problem before on other roms. Am I missing something as to why wifi is preventing my phone from sleeping?

I tried the market and searched google (only to find apps that help you sleep lol). I'm looking for a way to set a button on the home screen to press and put the phone to sleep instead of having to push the top button all the time.
