I've been trying to narrow down the battery leech on my Nexus 7. Something is keeping it from going into deep sleep; it will spend more than 80% of its time in wlan_rx_awake and 20% in deep sleep and a few others (with screen off and otherwise idle). For example I just rebooted about 2 hours ago and while PowerManagerService is currently the #1 offender since I've actually been using the tablet, for just wlan_rx_wake I've got 32 minutes and a count of 2204. Last night I saw the count at over 8000 and the majority of the time.

I've blown away the obvious suspects - apps that might be waking my device up like facebook or garbage like that. I've done a lot of googling and UTFSE, and have been monitoring BetterBatterySaver, Network Log, and CPU SPY. There are no single processes or appps that seems responsible on the N7 - I'm thinking it's some sort of wireless broadcasts from my d-link 655. Network log shows a lot of UDP packets from 192.168.0.184 to 255.255.255.255, with source ports either 32805 or 32806 and dest port 1234 or 53274. Some research shows 1234 is VLC USP stream and 53274 TCP is "Xsan. Xsan Filesystem Access" from Apple - but I don't find anything about UDP 52374 192.168.0.184 is my Seagate Goflex Home, my network attached storage device - which is also a media server. I don't use the media server component but it apparently can't be disabled (though I've thought of logging into the goflex via the secret ssh interface and killing the minidlna server for troubleshooting purposes[it's running an embedded linux].) I've already disabled UPnP on it and that didn't change anything. I've also gone to the 2 Windows 7 machines that share the wifi and disabled the IP Helper service; something I read somewhere suggesteted that. It also suggested disabling Shell Hardware Detection, but disabling that service disable Windows Image Acquisition, rendering my wifi-attached HP 3050 scanner inoperable. So I had to leave those running. I'm not seeing a lot of packets from that printer so I don't think that's it - I really am suspecting the Goflex Home.

I wish I could output from Network Log. The Goflex home traffic is broadcast in bursts of about ten packets with anywhere from 1 minute to 45 minutes between. That's why this is my suspect but it could be a red herring. Can anyone offer me suggestions on how to proceed? Is there perhaps a sysctl command I can use to tell the device to go into deep sleep quicker? I suppose I could just have wifi turn off when the screen does but I'd rather not, I like the benefit of having everything sync'd and up to date. For now I've installed DS Battery Saver which just intermittently turns on Wifi. Hasn't been long enough to know if that helps.

Thanks for any help!

tl;dr wlan_rx_wake is keeping my device from deep sleep, leeching battery, and I suspect it's my Goflex Home's network broadcasts but I'm not sure.

Edit: Attached BetterBatteryStats output log
[Samsung Galaxy Nexus] madd0g:
Did you try shutting the NAS down for some time, to really see if that's the culprit ?

Also one idea I've seen is disabling IPv6 on Windows clients in Adapter settings, which connect to the network, but this probably isn't the main case here.

Regarding output from Network log, you can enable monitoring in the app, so the log gets recorded to the storage. You can even filter the output before recording, so it's not crowded.
[Samsung Galaxy Nexus] jb0ne:
I've got it logging, and filtered right now for just the Goflex IP.

I have rebooted the goflex, but not shut down for a period of time. Since it's only a weekly backup server that's not a bad idea.

I have made some progress. I got root on it and killed the minidnla service as well as the mt-daapd service (the latter provided Itunes [and possibly Bonjour] service I learned). Even with those killed I'm getting the same spurious UDP broadcasts with the same UDP ports. Using netstat on the goflex I found that a service called "locator-server" was opening connections to one of the aforementioned remote ports (didn't note which). I can find very little info on this service in google though. The goflex's core is an Axentra so I'd think more info would be available but not that I could find. Here's what's in the startup script for that service:

# locator: UDP broadcast of HipServ's presence

# description: broadcasts UDP messages to announce presence

I *think* that locator broadcast is just for this garbage Seagate dashboard program which is not necessary for the function of the NAS and is not installed. But I'm not sure. I suppose I need to shut it down and see if I lose functionality.

I guess I before I spend more hours on this I need to answer a basic question: does a series of wireless UDP packets to 255.255.255.255 even keep the N7 in wlan_rx_wake state?

Whatever's doing it is hitting it hard, of 2 hours uptime BetterBattery shows 45 minutes wlan_rx_awake right now with 2nd place going to just 2 minutes of PowerManagerService.

Edit: well I killed locator and not 2 minutes later got another burst of traffic from it, to UDP ports 1234, 53274, from 32775 and 32776. I even did "netstat -cap|grep -e 1234 -e 32775 -e 32776" but got no output. Time to shut it off.

Edit: No longer getting the spurious broadcast packets, but the wlan_rx_awake number continues to grow. All apps look normal - google play, mail, currents.
[Samsung Galaxy Nexus] madd0g:
Hm, maybe try shutting down all devices in your network except the phone and router. That's the easiest route to troubleshooting with so many parameters - exclusion.

If this doesn't help, then you might want to borrow another router and after that it must be the phone configuration. But you'll know where to focus on.

A quick google for udp broadcasting to 255.255.255.255 says it might be the Apples Bonjour service. I presume you have some Apple software on the clients, so you might want to check that out. Try my suggestion above to see if it clears up when only the phone is present on the network and you'll know it's the other clients for sure.
[Samsung Galaxy Nexus] jb0ne:
Well I did a sort of test like that today - I took it to work. No issues at all with it going into deep sleep or wlan_rx_wake increasing dramatically. My battery lasted all day even with quite a bit of use.

Using Network Log I can easily see which systems are sending out the 255.255.255.255 packets, next step is to narrow it down as to what IP corresponds to what device. I can't shut all devices down, I have roommates.
[Samsung Galaxy Nexus] jb0ne:
With the Goflex NAS shutdown, my network broadcasts have dropped dramatically. At work I can use it off and on all day and still have 80% battery with 5 hours deep sleep. I get home and the battery starts to drop faster, and the wlan_rx_wake counter starts rapidly going up. But Network Log shows only normal things like checking email, no suspicious packets. I don't get it - why is it that at home the wlan_rx_wake counter just goes nuts and my battery shoots downwards -- it's now at 64%, down from 80% when I got home four hours ago, and I haven't even touched it.
[Samsung Galaxy Nexus] madd0g:
Then it's the clients or router, if thats also whats left in the network ;] As i said try to troubleshoot those, talk to roomates to shut them down for couple hours or something.. Maybe its just one particular client, with some kind of broadcasting **** which is waking your device.
[Samsung Galaxy Nexus] jb0ne:
Do you happen to know does any packet sent to the broadcast address wake an N7 up from deep sleep?

Also shouldn't they be showing in Network Log? It's like wireshark so it should be showing any packets I receive.
[Samsung Galaxy Nexus] madd0g:
You can also go through some tips in here : http://xdaforums.com/showthread.php?t=2133176

The NetBios part was happening in my home network and I saw those in Network Log app.
[Samsung Galaxy Nexus] jb0ne:
Thanks, those are good tips I hadn't stumbled across that thread. I don't think I can disable netbios (I'd have to google how to do that anyway); I do my backups and file storage to a Goflex NAS via Windows networking and my wife I and I share some files between our Windows 7 machines. I also can't turn off Shell Hardware Helper service, as it seems to be needed for my network scanner. I did turn off the other services already "IP Helper" and "Windows Media Sharing Service" with no change. I've already got all systems that I have control over getting a static IP from the DHCP server, though I realize that's not the same as setting a static IP. But if I set a static IP I'll have to disable it when I get to work and re-enable when I get home. If I just spent my time on one network that'd work. Actually though for testing I could do a static I suppose. It's not possible in 4.2.2 to set a static IP on one SSID and DHCP on another is it?

Network Log is really not showing much NetBIOS activity anyway - seems like dhcp requests are the most common broadcasts I'm seeing.

Biggest revelation from that thread was that Network Log doesn't capture all packets! - I'd need to put Shark for Android on my N7 then transfer the file to my desktop and use Wireshark to look through it. Ugh, time consuming but I may have to do. Another thing I can try is disable IPv6 on my N7 but it looks like I need to install Android Firewall to get to that setting, it's not accessible otherwise.

Edit: Changed my DHCP leases from 24 hours to 7 days. I found these interesting checkboxes in my router config page though (Belkin d-655):

Enable DHCP Server: X

DHCP IP Address Range: 192.etc to 192.etc

DHCP Lease Time: 25200 (minutes)

Always broadcast: X (compatibility for some DHCP Clients)

NetBIOS announcement: X

Learn NetBIOS from WAN:

NetBIOS Scope: (optional)

NetBIOS node type :

Broadcast only (use when no WINS servers configured) X

Point-to-Point (no broadcast)

Mixed-mode (Broadcast then Point-to-Point)

Hybrid (Point-to-Point then Broadcast)

Primary WINS IP Address: 0.0.0.0

Secondary WINS IP Address: 0.0.0.0

I wonder what would happen if I turned off those two broadcast options....

I tried changing to hybrid mode, then making 192.168.0.1 (my router) as the first address. All sorts of things went awry then. I could get to the internet despite the Network and Sharing Center showing an X. Also when I tried to browse my network, it said File and Printer Sharing service is turned off, do you want to turn on? I'd hit yes and a second later would do again. I went into the Windows 7 settings and everything regarding sharing had been changed to no. So I turned them back on (I also share a printer from this computers) And I reverted back to broadcast only on the router and now I can browse my local network, but the goflex didn't show up under Network until I went there by hand (\\goflex_home\) in an explorer window. Very odd. Maybe I'll just stop wasting time with this before I break something, and just use DS battery saver at home.
[Samsung Galaxy Nexus] jb0ne:
Well, I've not made a little progress, my tablet battery can last overnight now. It still spends many hours in wlan_rx_wake (6 hours) though deep sleep is finally beating it (17 hours). The only significant changes I can think of were disabling "IP Helper" and "Windows Media Sharing" services, and disabling DLNA and mt-daapd on my goflex_home. To do that I had to ssh in, and chkconfig'ing them off didn't work - I had to rename their startup scripts /etc/init.d. I think it was the latter that helped the most as Network Log showed most broadcasts coming from it. I'm still curious if any broadcast traffic on the wlan is enough to trigger the N7 to wake up from deep sleep. CPU Spy shows most cpu time in Deep Sleep now, with the next highest being 340mhz.

Hope this info helps someone else.
[MDA II, XDA II, 2060 General] chriswo:
I've had this problem for some time now and I have no words to describe this symptom ... I know I'm not alone as I know a few other people have the same problem:

The signal bar on Xda II shows ok, green LED still flashes like normal, even my Phone Dashboard showed that I'm connected to my mobile operator with signal strength >90% ... Nothing is suspicious until you start making calls, everything stays at "Dialing ..." and there will be no dialing tone !!! Make another call, same ...

Then you'll use the landline to call yourself on the mobile, it goes to the voice message ... All those time, you were actually not connected to the mobile network! When you realise this, the only remedy is to turn on and off Wireless / Flight Mode.

Now, have you had similar experience ?

I think, somehow the mobile network lost you, and Xda II didn't even notice it therefore did not bother to reconnect as it thought it was still connected. Is this it ? Or anyone has any other theory or solution to this irritating problem ~ which I genuinely have no idea who to blame ?
[MDA II, XDA II, 2060 General] tomerbn:
i think i know what the problem is

:idea: try to download and install this software,

http://www.gb-soft.cz/xdaii/product_gprs_tweak_en.htm

and in "gprs settings", disable "gprs always online", and set it to "search gprs on start gprs connection".

that way, you will be connected to your operator as simple gsm phone, not a gprs one.

the mobility managment in this status (imsi attached, instead of combined attached) is more simple to the network, and you won't lose service.

Hope it will solve your problem,

please update...

[MDA II, XDA II, 2060 General] chriswo:
thanks i have downloaded it and installed, and set the "GPRS always on" to false, but the other one was default ticked ("Search GPRS on start GPRS conn").

i will start my observation today and see if the problem reproduce itself.

did this solve it for you?
[MDA II, XDA II, 2060 General] chriswo:
Coming into the 8th day with this Tweak installed, with GPRS set to search on GPRS start (not radio start). So far, the network problem has not occured. I would like to give it another 2 to 3 weeks before announcing the problem solved.

However, just one little note, after installing the Tweak ... a day or two I noticed that the BT Icon no longer shows on the main screen task bar even after numerous soft reset. Not sure what causes it.

how many times did you put your charger in the freezer?
[Eee Pad Transformer Q&A, Help & Troubleshooting] GuestK00429:
What do you mean? Your TF101 is not charging? Or is it trickle charging and only when off? If so, then go to the shop you bought your tablet from or any electronic/asus shop around you and ask them to test another cable and/or charger block with it and it should work. Trust me, I've wasted months testing different ways to make it work, including the freezer one and I found out that the cable was the problem.

Good luck.

Place the restored file in sdcard/clockworkmod/backup.

Mount sdcard manually and try flashing.

There is flashable thing called aroma filemanager,which you have to flash,so you get touching sensed file manager,where u can browse the sdcard,Use this becose to check whether the cwm can detect sdcard.

google aroma file manager...

[Xperia Z Q&A, Help & Troubleshooting] RoChinu:
Did you try to uninstall or force close Play Store from settings and clear cache before using the VPN? I suppose when you first do what I said and then connect to a VPN app, afterwards open Play Store it should be the country your VPN's IP is connected to.

Force Close Play Store from settings, clear cache, activate VPN, open Play Store.

Try it, it should work.

It has stock firmware with no bloat. We can assume we will get updates when they are released not a month or more later whenever the carriers release them. And while yes you are right about being able to bootloader unlock currently they may not remain for AT&T. It also could be disabled through a OTA (over the air update) which we would never have an issue with no matter what update we take (dev edition people) we will always have a unlocked bootloader.

Last they only charged tax in TX CA for the dev edition so for most who didn't have a upgrade or were on MVNO's it was the cheapest option.
