WI-Fi with screen off - Nexus 7 (2013) Q&A

Hi.
I don't have any problems like wifi dropping while browsing at my home, college or gf's house.
But when i turn off the screen after a while (can be 5 minutes or 30 minutes) my downloads stop (big games from the store, torrents,etc). They resume after i turn on the screen.
Also messages received from email and messengers are unpredictable. For example, while writing this post, i received a notification from hangouts on my N7 5 minutes after i received on my S3. Other times i only get the notification if i turn on the screen.
The battery status and wifi analyzer show me wifi was always on.
On wifi settings, keep wifi on during sleep option is always on, like i want.
This happens on 3 different locations with 3 different isp's.
This doesn't happen with my other 2 android devices.
Any ideas?
Thanks

Let us know if you figure it out.

Did you read my post?
That option is always on like I wrote and highlighted in bold.

It seems that for a few minutes it ignores the option to keep wifi on. Any ideas?

Sounds like the N4 issue to me. Try one of the tips from this thread: http://forum.xda-developers.com/showthread.php?t=2072930

Try installing Juice Defender from the Market. Works for me.
have the wifi and 3g on off buttons as widgets on one of the home screens, and turn them off easily when not needed, like sleeping, takes a few seconds to reconnect, saves alot of battery for me

thank you for this. just curious, if we have to use widget to control the connection, what is the policy designed for? do I misunderstand the purpose of that or it IS not functioning rightly?

the policys are for automated controls, so its meant to turn off after 15 mins or whatever, i keep it as a widget so i can turn them on and off manually as i generally have the wifi or 3g on all the time for gtalk etc
i turn the 3g off when going under ground, sleeping or in a meeting where i wnt be needed it. its easier to do manually then wait for the automated to kick in in my oppinion

i do want it automatically turn off the wifi for me. i think my problem is that even i set it to "after 15 mins", the wifi is still on even after 20 or 30 mins after i turn off the screen.
Usually it will stay off until you awaken the screen (phone) by which time it will try to re-enable itself for your convenience.

i tried the setting in Nexus as well. In Nexus, it is not "after 15 mins", but "when screen turns off". unfortunately, even you check the wifi status after you turn off the screen 10 mins later, the wifi is still on.. totally no idea how that is supposed to work..
How are you checking whether the WiFi is on? By waking it up again, or seeing whether it is connected to your router?

Yes that works for me to, just a simple quick press on or off and no worries about it using battery life when you dont want it to.

[Q] No 3g during night hours, sleep mode?

Dear all,
Is anyone else experiencing the following problem?
When the phone goes to sleep mode during the night hours it wont receive any messages for whatsapp etc. It seems that it turns off the 3g connection when you turn the screen off during the night hours.
Does anyone know a possible fix for this?
I have gone through all the settings and could not find anything about this.
Cheers.
I recently got this on my Desire Z too, and I have not changed any settings on that. Then I noticed it's happening on my One X too..
no 3g late night
Hi there, i have a motorola photon. in the settings menu you can go to what is called battery and data manager. then tap on battery mode. it's default is set to nighttime saver, which will kill your syncing after 15 minutes of inactivity in the hours between 10pm and 5am. i set mine to performance mode. this will sync all of the time and i don't really care if it takes up battery since i am awake and ready to pop in a new battery off my kick a$$ battery dock wall charger!! hope this helps....

I think it's got something to do with what HTC said about "the phone learning" when you check things like mails ect.. so after it has learned that you do not check mail (for instance) during the night it disengages activies... or not
@mykeyvee, there are no such options in the stock rom on this phone.
Anyone have any other ideas?, i want everything to be synced 24 hours a day.

I don't think it's anything to do with settings. My Desire Z is on 2.3.7 and only recently have I got this bug.
My One X is stock unrooted. No settings for power saving.
Accounts and sync>sync schedule>smart sync
Is this what is effecting you

This. I woke up and my 3G wasn't even on. I had to disable and enable data again to get connected.
Same problem here. Whenever my phone is in standby mode for a longer period of time (as far as I've seen it doesn't matter whether it's during the night or day), the data connection (3g) is disconnected.
On my previous phone, a desire Z, there was a setting 'data always on' which addressed this issue. This setting however seems to be missing on all android 4 phones.
**edit:
Contacted Dutch HTC support; they claim it's a feature. Hope they restore the setting in the future..
I have noticed this too this morning.
I woke this morning and went into the battery settings and you can see the graph that all data was shut off over night.
How do we fix this.
Piss. Wondered why it used virtually no battery overnight...

Exactly same here...just as u switch on the screen....it connects to wifi or 3g instantly...

I was thinking that maybe it was just the 3g/wifi connection which was going into a sleep mode after a long period of inactivity.
I've tried increasing my mail sync at night to once in 30 minutes to prevent the 3g connection from going to sleep and disconnecting. (had it at once in 4 hours)
Now when i wake up and turn the screen on, the 3g icon is already there, and my mail has been synced last in the previous 30 minutes.
Fixed it?
Same issue here, weird thing is that I can't seem to tie it down to either a specific battery-percentage nor a specific time of the day. It's really annoying though, as I would like my device to be connected 24/7. Tried setting a mail-account for 15 min update, so will see how much wifi/3g has been on tomorrow.
Edit: Definitely not a battery issue, but rather a time issue. Battery is at 80% (used the phone little today) and 3G/wifi has been disconnected for the past 2 hours even when mail is set to check every 15 min. I can see that for many people it's not important at night, but I wish we at least had the option to turn it off :/
Possible Fix
Download this app.. Minimaltext
https://play.google.com/store/apps/details?id=de.devmil.minimaltext&feature=search_result
Create a widget 1x1, under the tap behavior, select start another activity, then select an activity. Scroll now to settings, expand it, choose power saving setting..
Leave the rest default then press okay.
Click the widget and you will find some settings, including put data connection to sleep when screen is off. I haven't tried it. Hope this helps.
Not a bug!
This is not a bug, but a feature : scheduled standby mode
If on Sense 4.x, settings are similar to Sense 3.5, you should go into settings > power then scroll to standby mode. Default setting is auto, which means that the phone learns your sleeping phases and disable every wirless connections during this time when your screen is off, and enable it again automatically when you wake up (even if your screen is still off).
You can disable this feature, or (my favorite option) manually set the duration when you allow your phone to enter and exit deep standby mode.
(For me it's a great feature, as I really dislike having my phone producing airwaves close by my head when I'm sleeping. Before I went to Sense 3.5 on my DHD, I didn't have this option and had to enable plane mode before sleeping ant enter my PIN code every morning to exit plane mode, which was less convenient).
If you want to disable this, download smartsync disabler from the play store. Im pretty sure there is a thread on xda too with an app available to download.
...Or read my previous post... Market's bloatware is not needed, setting for this should be in power settings, as on Sense 3.5.

[Issue] Display turns on periodically by itself

I've got a small issue with my N7. Since I bought it, my display turns on periodically without touching it or hitting any of the buttons. It seems, that the time periods inbetween are always the same (e.g. today its always 24 minutes after a full hour when it turns on). It just displays the lock screen and turns off again.
Is there a possibility to find out which app or service is causing this? As far as I can observe, there are no notifications coming in which could potentially turn on the screen.
I'm on stock 4.3 and switched meanwhile from the stock kernel to that one by faux123 (problem occurs with both kernels)
Thanks for your help!
The screen does not turn off
The problem with my N7 Wi-Fi is that the screen does not turn off. On the Nexus 10, the screen turns off within a minute.
On phones and the Nexus 7, when plugged in, the screen never turns off. Many customers have been complaining that the screen turned off at unsuitable times, so I think Google went crazy with it.
On my Nexus 7, the display is turned on by incoming Sipdroid calls.
What you can do is to look at logcat, but it will cost you tons of time to figure it out.
It occurs to me while the tab is unplugged. Perhaps i check if it also occurs in flightmode. Then i could see if wifi or an other connection is the problem!

Wifi disabled to extend battery life

What is the point of this? My watch has 56% battery, so why does it disable wifi? That's the whole point, so I get notifications whole I am away from my phone. If I swipe the notification, it say tap to re-enable, but it doesn't re-enable it. If I go to wifi Settings, it connects momentarily, but immediately shuts back off. WTF?

It's by design. It only momentarily enables WiFi when out of Bluetooth range to obtain notifications, then disables to save power.

I actually think this is a good way to handle the wifi connectivity on such a small battery. I've been VERY happy with this update.
Does anyone know how long it stays disabled before turning it on to check for notifications? If it is off for 15 minutes before it turns on, that is too long.
The link above says 'every few minutes'
So I did a test. I disabled bluetooth on the phone, sent my self a text message. I assumed the Wifi would turn on every couple minutes, but it never does. I waited twenty minutes and never got notified of the text message. Kind of defeats the purpose of having a wifi connection if it never gets you the notifications you need.
I think once you get the "wifi disabled" message, it will never turn back on again, unless you do it manually.
I don't think it will work with SMS as there is no system in place for the phone to send the message to a server and then the watch to retrieve it. It should however work with hangouts messaging using your gmail account.
Update: my above assumption might be wrong as I just read if both phone and watch are on the same network then they may communicate together using the internal IPs.

I wonder what uses less battery, the 360 with Bluetooth connected or with WiFi connected..
Edit: I am an Xfinity customer. I will be using my watch WIFI ONLY to connect to my notifications through Wear's Cloud Sync. With access to over 10 million hotspots, let's see what we can figure B)

Hi,
Like you, the intempestive cut of the WiFi signal when I got over 60 or sometimes 70% of battery make me fell sucks against the watch.
But I try this, and it seems working :
Go inside developers options
At the bottom of the settings you should find "activate /disactived wifi automatically", by one tap you turn it off. No more ****ty battery save

Great find! I prefer for it to stay off but have been keeping it on all day with Bluetooth off, and there's a definite difference in battery life. I'll post results and screenshots

Thats a good point on internal IPs, thanks. I thought as long as they are on wifi (I have phone on 5g and watch on 2.4 as they all decided 5g takes too much batt) so I was wondering why I was losing conn. so often I was getting so frustrated by that.

I was also getting real mad with this, until I accidentally saw that a left swipe gives a re-enable option.
Now I think it is a good option - they just need to make things more intuitive with hints on these screens on what actions we can take.
Like vibe watch or phone when devices lose connection.
Update - I dont see that option anymore and my SW3 now keeps disconnecting like a mo4 even when on same SID
Where do I find this in developer options? I went through all the settings on S4 and cannot find. I want to run only on wifi so I can roam anywhere without my phone being within bluetooth range.

WiFi Long time to connect - workaround

My Nexus 5X takes around 22 seconds from enabling wifi to achieve a connection.
I think this is excessive, especially when my last Samsung phone only took 4 seconds.
I use Leandroid to control wifi switching, so have to wait until I can check for emails or browse the net. At times this can be very frustrating.
The issue was present running stock and my current custom ROM, latest Pure Nexus.
So it looks like the problem resides in the Google OS.
Does anybody else have this issue?
If so, you may be interested in a workaround that reduces the 22 seconds to around 4 seconds.
It involves opening wifi in settings and is best accomplished using an automation app. I use macrodroid with the following macro
T - Screen unlocked
A - Enable wifi, Launch Shortcut Settings shortcut, Wait Before Next Action 1 sec, Press Back Button
C - Wifi Disabled AND 06:00 - 23:00
The macro opens the wifi setting screen for 1 second before it is closed followed a few seconds later with wifi connected. The macro constraints ensure the macro is only run after Leandroid has switched off wifi and only during the daytime, but you can have different constraints.
I would prefer the issue is resolved by Google but for now can live with this workaround.
Nobody having the same issue!
Suggests this might be a fault with my phone rather than a software problem.
Please let me know your wifi connect times with the ROM you are using.
Thank you
I have the same problem however I don't care about it as much as you do. Unrooted nexus 5x user here. Sometimes it doesn't connect at all if I don't expand the WiFi in quick settings.

I have this issue with my original and replacement 5X. No idea why it takes so long. I hope a mini bug fix will help it out when the new unicode update comes to us in the form of next weeks update.

My stock 5X takes roughly 12 seconds to connect to Wi-Fi, so I started doing this. Expanding the Wi-Fi in QS drops the Wi-Fi connect lag to 4 seconds or less for me. Much better experience, yet still an annoyance that I have to do this.
Edit: To clarify, tapping Wi-Fi in Quick Settings causes a severe lag of 12 to 20 seconds before it connects to my home Wi-Fi. Expanding Wi-Fi in QS cuts that time to just 4 seconds which is normal for my other devices.
