I am wondering if it is something with this phone. I am not using JD but rather Green Power (same as JD) and it seems to have an issue shutting off data as well. I ended up using Llama and setting a condition that whenever the screen goes off to kill data and vice versa. It has been working great.
Tried it for a day and noticed that my phone couldn't connect to data even when wifi was off other users also had the same issue so I've steered clear of it since besides while using it really didn't see much of a difference in battery life

It seems to still be working for me? It has always been working for me.. I have juicedefender ultimate don't know if that matters?
Its working for me! It always has..

i have gotten both results. some days it does work, some days it doesn't. when it chooses to work and when it doesn't occur at random times, and i'm not sure what i do that makes sure that it works as it should.
i wonder if this issue and other reports of settings being reset after a reboot are phone related or firmware related...
It worked today after I went to the status page and tweaked some things.

what did you do?
In the "about" tab there are different options, this is what I have; enable after unlock is highlighted, disable on wifi (data) (4G) are highlighted, all the rest are not highlighted. Of course I have the app itself enabled with aggressive highlighted. Notifications needs to be allowed... been working ok for 2 days now.

Has been working for me as well. Using ultimate, advanced settings, basically have it set to turn off data while screen is off, sync every 5 minutes, using location for WiFi for home and work. averaging 1.85x. Data does not turn on when lock screen is checked, only when phone is unlocked. At that point, I see the juice defender icon has a red dot to indicate no data connection. It then turns blue and cell data turns on momentarily while wifi connects. The pull down menu indicates "screen" as the trigger got starting data.
Rooted just the other day, flashed the stock minus bloatware ROM (tesh's streamlined version 1) yesterday, juice defender still working fine.
Its working fine for me.

This thing works well for me but
i'm not sure about the features that require root. Id be very curious to hear if anyone has got the 2g/3g/4g toggle to work as well as any of the other features that require root on the stock ROM.

I just bought the Ultimate version. I intend to put some screenshots up after a few days to show if there are any differences between the battery life I have been experiencing with this phone and what I experience with Juice Defender installed and working on it.
Obviously, there will be some tweaking going on to get it set up properly but hopefully I will have everything figured out very shortly. I have high hopes for this application though I realize I am likely going to have to root the phone to gain access to the 2g/3g/4g toggle function. That is likely to save me the most battery power when I am out of the house and office while still allowing synchronization all of the time.
It worked good for me just had one complaint. It takes a few secs to connect from screen off. But it does save some battery.
Is there an app I can use to see what apps are accessing Gps ony phone? I swear every 5 minutes Gps is activating and trying to locate me! I think it's really hurting my battery life.

Wipe cache nd dalvik and fix permissions, as of gingerbread programs cant effect GPS directly.
So its ur config, sorry to have to break it to ye..
Also, side note, if no GPS required apps are running, ur GPS doesnt actually try to triangulate unless requested.. so..
Basicly it would be using ur battery if on, but no connections would really be made unless u see the triangulating icon by clock..
That's the icon that I always see. It blinks a few times then stops. Sometimes it stays solid for a a few seconds before it turns off. could it be Google latitude causing it?

Quite possibly actually. Try clearin data for it and maps then booting TO CWM and clearing cache and rebooting
Did as you described. Problem still there. I can't understand. It's even blinking while I type this!

OK I discovered the culprit. Skyvi was trying to Gps my location at all times. I guess their new beacon feature is not really optimized yet.

I've been having this weird issue that when I use my nexus as a wireless adapter for my computer (turn on wifi and enable usb tethering), the performance of the wireless connection significantly degrades when the devices screen is off.
For example, I play an RTS game that is very latency dependent, and when the screen is off my ping rockets up to around 600 ms but when I leave the screen on it goes right back down to the normal ping for my connection which is around mid-80s in ms.
I've experienced the issue with the stock rom and with the liquid smooth rom, and I'm inclined to believe that it's an issue with the power profiles for the wifi or something (different radios have not fixed the issue).
Has anyone else had a problem like this and does anyone know if there is a fix? Thanks.
Radio has nothing to do with wifi.
Try a different kernel.
Sent from my i9250
franco.kernel has a setting for this.
There is also a app ....wifi high performance that will stop it too.

It's not a problem, its a feature. You can fix this with custom kernels but the reason this happens is to save your battery when your not using your phone.
maybe this will help

Hi all,
I have 4.0.4 stock gnex.
My wifi settings are this:
Settings->Wifi->(Menu Button)->Advanced. It's listed as "Keep WiFi on during sleep"
When the phone go to sleep the wifi seems to stop, I am downloading an app
from the market, when the phone go to sleep, the download sleep.
Not to doubt you on this but does it also say "Always" beneath the "Keep Wifi on during sleep"? If so, perhaps you have an app that overrides that and disables it.
I have no app that can do it.
Hi, I just tested and had no problems downloading a 50 meg game with screen off.
From honeycomb on google changed how wifi was handled when screen is off. This gives similar problems with older applications but should not be a problem for apps made by Google like Play and Music.
You still did not answer the previous posters question. You reference the advanced wifi setting but not what it is set to.

It's obviously set to always
People have had issues with the setting you choose in that menu not sticking. Try toggling it back and forth and doing some reboots. I don't have the issue on 4.0.4.
From what I understand, when the screen turns off wifi goes into a low power state, draining less battery when on standby. So it greatly reduces the speed (sometime pauses) of all connections to save juice.

I understand if it slowed down, but it shouldn't ever pause though.
This low power state is what I referred to in my previous post. An app must now explicitly request that high power wifi mode is retained when screen is off. All apps from google should be doing this already.
Unprofessional app developers that have not been reading up on the latest changes in android api (like Audible!!! shame on you) will have major slowdowns downloading over wifi when the screen is off.

I have the exact same problem as posted here And I may have found the solution at this other link here.
What seems to be working for me is the change the "Keep Wi-Fi on during sleep" to "Never (increases data usage)". That totally does not make any sense to me. If you 'never" keep wifi on during sleep it should *not* increase data usage. Anyway, I have noticed two things:
1) If I set it to "Never," the files continue to transfer when the screen goes to sleep
2) Wifi transfer rate seems to be *much* faster on my home network. I'm using ES File Explorer, so it could be app related.
Just discovered that according to Google, "Never (increases data usage)" means that it will not stay connected to WiFi while asleep which will increase your 3G/4G data usage. Never the less, it seems my Wifi is better when set to "never"
I wrote an article about wifi usage on my blog here: http://zapek.com/?p=262
You shouldn't worry about PS-Poll mode. It's fine for downloads usually as they don't require a fast interactive response.

this could be a possible reason, in my office wifi is not really powerful,
a low power state can disconnect the wifi.
I'm checking better the problem, it seems that the wifi goes into some sort of
energy saving mode when the screen is off that drop my wifi speed.
Is there a way to solve this problem?
it seems that I'm not the only one with this problem-

This is not the same problem that you have. The thread you link to is about general download problem with screen off. Your problem was about downloading from the market while screen is off.

In your original post your wrote that you had problems downloading from the market with the screen off.
The android market is a google app and should not have the problem discussed in the thread you linked to.
The problems in the thread relates to applications that have not yet been updated to support power saving features in resent android versions.
So your problem is not the same.
I did write this in my previous posts from may 25. but maybe it was unclear.

Hey its no problem. It's only that this is the first time you state that you have problems with all apps.
I still don't understand why you have problems downloading apps though. I have tested and do not have this problem BUT I do have the problems with most other 3rd party apps.
Anyway there is a fix that probably will help you. Download "WIFI High performance' widget from the market. Add the widget and enable it. Good luck.

Something on my Gnex is going GPS crazy today after the 4.2 upgrade. I've tried disabling Google Now, checking logcats for likely suspects, freezing various apps, but I can't narrow it down. It's causing battery drain and preventing deep sleep. Any ideas how to figure out which app has been calling for GPS so frequently?
Sent from my Galaxy Nexus using Tapatalk 2
Yeah my GPS won't even lock after I did the upgrade yesterday. I dropped my phone also so that could be the reason idk
I still don't know which app is responsible, but I realized I've been getting constant data dropouts today. Every time data comes back, the GPS icon pops up for a little while. Tried flashing the H1 radio and I'll see how it goes tomorrow.
Sent from my Galaxy Nexus using Tapatalk 2
Bump. Is there ANY way on Android to track down which app is responsible for firing up the GPS?
