Hello!
I finally received my OnePlus One and after setting it up I noticed that the phone will not turn off WiFi in sleep mode even though it's set to Never keep on WiFi during sleep. I suspect a wifi lock of some sort and I'm also noticing that after a period of time in sleep mode, wifi will periodically turn on and off for short duration.
I installed BetterBatteryStats, Wakelock detector and GSAM Battery Monitor but I can't find a clue as to what's keeping the WiFi on, or why.
Another thing I just noticed is that when charging now for the second time, the notification LEDs are not turning on while charging or when it's fully charged. It worked for the first time when I was charging it yesterday.
I am running all incremental upgrades (2 were installed when received yesterday), the device is rooted.
Could you help me find the app or setting that is keeping WiFi enabled and sometimes prevents the phone from entering deep sleep?
Thank you.

Go into Settings>Wifi>Advanced and uncheck the "scanning always available" option.

Already done when I first got it. But thanks.
Does anyone have any idea on the charging light though as well ? It's enabled in the settings, everything is set up as it should be, indicator is working for other notifications but it's NOT turning on when charging or when fully charged.
EDIT: Figured that LED part out: turns out I accidentally disabled it during the quiet hours. :silly: But I still have the peristent WiFi on problem :/
So you're not getting any wakelocks show up when investigating via any of the apps you mentioned in the OP?

No, nothing significant. And most of the time phone is not awake but wifi still stays on.
Are you actually experiencing bad battery life?
Transmitted via Bacon
I'm not experiencing a bad battery life, no. But I'm still interested in what's keeping the WiFi on when I explicitly set it to turn off when screen is off/phone is not awake. "Never settle", I guess.
Bump - so, is there a way to detect "wifi locks" and apps that turn it back on periodically while sleeping?

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.
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.
Okay, I've been trying to diagnose a somewhat annoying issue. I've been using a fairly simple set of conditions in the Llama utility to automatically disable Wifi when the screen turns off in CM7 to prevent a wakelock condition and reduce battery drain.
So I activate wifi, I reset the log in CPU Spy, and I lock the phone disabling the screen. When I reactivate the phone and check CPU Spy, wifi was definately off but the phone was never in Deep Sleep, so something was holding the wakelock I guess. I repeat the experiment with no changes and Llama still running, but this time I manually disable wifi before locking the screen. This time the phone immediately goes into Deep Sleep according to CPU Spy-- it works perfectly.
So what is the difference between Llama autodisabling and manually disabling wifi that leaves a wakelock active? I've repeated this experiment like ten times last night, and it isn't making much sense to me.
Thanks,
Gnat
I would love an answer to this as well. I can add that with juice defender ultimate the same thing happens. It will disable the wifi but the wakelock stays active. I have tried several settings and reboots and tests and the only thing that would get my phone to deep sleep was disabling JD.

I can't tell whether this is the exact same, because you make it sound like JD has the wakelock. In my case, Llama is running in both tests, the only difference is whether Llama turns off Wifi or I manually toggle it-- manual toggling puts it into deep sleep even with Llama running.
On the general battery issues on Triumph, one of the more helpful discussions I've seen is this one here-- http://androidforums.com/triumph-all-things-root/456795-cm7-triumph-battery-life-improvement.html. In it a quote from Tickerguy blesses the JuiceDefender approach to throttling data use for battery savings, but I don't think he had done any analysis regarding wakelocks. BTW, I reverted to stock today, and I am finding the exact same problems as CM7-- wifi imposes a wakelock, and Llama can't shut down wifi automatically without the wakelock persisting. I have to manually toggle wifi off before screen off before the wakelock is gone.

Gnat

Sorry; the wakelock is WLAN. It is almost always active if JD is toggling wifi. I hadn't tried disabling wifi manually but leaving JD active yet. I just tested that and got deep sleep immediately. So it must have something to do with how it disables wifi isn't releasing the wakelock.
You know, after switching back to stock from CM7 I'm really not sure I'm not happier. With CM7 I was getting worse battery performance, which led me to start obsessing about wakelocks and deep sleep. Now that I am back on stock, I do the same analysis and see that I have the same problems with wakelocks and deep sleep-- but the battery performance is better so it's not that big a deal. I'm sure that there are things I could do to make CM7 have better battery performance-- but I wasn't enjoying the process and wasn't finding answers, so why bother?
It's like power management programs. I ran Green Power for a long time, and had some glitchy problems with being unable to get wifi to turn on even though it wasn't supposed to be managed while the screen was on. Then I disabled it, and you know what... my battery life was good enough to get me through the day. Froyo is good enough to get me through the day.
The wakelock was put in there on purpose to prevent the phone from hanging when WiFi was on and the phone went to sleep. I use my power widget to turn off WiFi before I turned off the screen unless I'm actually using it.
You could try and build it to see if removing the wakelock is still necessary. If you need help on that side, just post and I'll help. It's not hard, really.
This topic has been up a couple of times before, perhaps most interestingly discussed in this thread.
It appears the problem still exists (asusdec_wake kernel wake), and I'm experiencing extreme battery drain during sleep with the dock attached. Currently running Cromi-X 5.4, and I have tried hunds 3.4.4, and _that 8 and 9 kernels.
It appears to behave as following: The tablet enters deep sleep with low battery drain (0.3% per hr with wifi off), and after a while (have seen it happen after a range of 1 - 5 hours) it starts draining quickly as asusdec_wake wakes the tablet up. It only occurs when the tablet is docked, it can occur at both high charge levels and when the dock is empty (mine always drains to 0%). It does not seem to matter whether wifi is on or off. I monitor the battery with better battery stats.
It's a real pity, since I have to turn the tablet off whenever I want to keep the dock attached.
Is anyone else experiencing this drain? Any suggestions for fixes?
Also: obligatory first post thanks-for-making-my-tablet-great to @sbdags, @_that and all the other contributors to Cromi :good:

How do you know that it first enters deep sleep and that it's woken up later?
asusdec_wake is a wake lock which only keeps the tablet awake, so the question is what causes the wake up and keeps the wake lock?

It might be a strong assumption, but it's based on the battery drain patterns I've seen. I've tried to monitor this a bit the last few days. Usually the battery drain is as expected during sleep for a while (whenever I check during this period, the asusdec_wake has not been active and the entire period the tablet has been in deep sleep), before it increases and stays high. I attach some screen shots where this can be seen. The change in slope in the battery graph is after about 7 hours. In those screen shots the deep sleep time reported by bbs was 6h24m. I'm not sure the reason for suspend_backoff, but I assume something is forcing the tablet to stay out of deep sleep. If I disconnected the tablet, there are no issues with suspend_backoff (and naturally not with asusdec_wake either).

Try turning location services off completely for me in settings.
Does that help? Give it a reboot as well.

Yes it did, thank you! 21 hours, only 3% down and asusdec_wake inactive. I will report back if things change.
Will add always turning this off when tablet screen is off to Tasker. Interesting that it caused this huge battery drain, given that gps and wifi was off anyways. Wakeups from com.google.android.gms decreased from many to nearly none when turning off location access, perhaps it is sufficient to turn of google apps location access in settings.
Thanks again!

It's Google now constantly polling for your location as far as I can tell.
Hi, everyone.
I've noticed that, sometimes, my phone will only connect to a Wifi network after I turn the screen on, regardless of how long I've been inside the range of a particular acces point. For example, when I get home and I go to check my phone after I've been in there for a long time, I see the Wifi connecting right after turning the screen on. This isn't normal, is it? How can I fix this? I have it set to always active if that matters.
Thanks.
Most likely the phone is in deep sleep and doesn't scan for the WiFi network until you wake it. The alternative would be the phone waking itself to check, possibly "WiFi Always Scanning" would accomplish that.

Thank you, bblzd.
How long does it usually take for the phone to go into deep sleep? beacuse this has happened for example if I get out of the office for a while (a few minutes) and then go back in. I'll try the always scanning suggestion, but would it have a considerable impact in battery usage?

It should enter deep sleep as soon as the screen turns off, unless there is something using the CPU then it will stay awake or wake itself as needed.
Always scanning does use a significant amount of battery compared to if you were disabling the WiFi. However if you leave your WiFi on all the time anyways it shouldn't make any difference.

Alright, I don't usually turn wifi off, so I'll try that.
Thanks again.
Didn't work, unfortunately.
Anyone else? I seem to be the only one experiencing this, can't find a single post about this online.
Any suggestions? I've tried rebooting into safe mode, turning data off, turning airplane mode on and enabling wifi, wiping cache partition, nothing helps. Still thee same behaviour.
