Slow WiFi with screen off - Nexus 7 Q&A, Help & Troubleshooting

I am running CM10 on my Nexus 7 and Galaxy Nexus, but I had this issue on stock as well (Galaxy Nexus 4.0.4 worked though).
Whenever I am downloading a large file, I usually turn the screen off. However, when I turn it back on 15 minutes later to check the download, and it only downloaded a small fraction of the file! Both devices have WiFi set to never sleep.
In a short test I just did, 20 mb to 24 mb took 8 seconds with the screen on; 24 mb to 26 mb took 1 minute with the screen off. (Nexus 7, same situation on Galaxy Nexus)
Is anyone else having these issues? I know I am on a nightly ROM, but I had these issues on stock Jelly Bean as well (even some ICS on the Gnex).

Supposedly it is a JB feature to throttle down the connection with the screen off. There is an app called WiFi High Performance Widget that you can use to keep it at maximum speed.
It's free but listed as not compatible with the N7 even thoug it works fine. I've uploaded it to my box account, you can download it here.

Wow nice, thanks! Works great. Just wish I could hide the notification. Hopefully this can get baked in to CM10 :good:

Thanks for this, I can listen to streamed music now in standby.

Will try it later
Thanks. I will have to try this later.
This definitely sounds like a "feature" that should be OPTIONAL.
Crazy that we have to download another application to fix it.
The stock N7 slows down my wifi so much that I have to turn on my screen after every song Pandora plays.
When I turn it on Pandora seems to buffer enough of the song or the entire song and after it is over... nothing, turn on the screen and the next song starts playing.
Perhaps before Google does a new release, they should stress test any application with 50,000,000+ downloads.

permissions
I can see why it needs...
System tools
connect and disconnect from Wi-Fi, prevent tablet from sleeping
But why does it need...
Phone calls
read phone status and identity, reroute outgoing calls

phone randomly reboot / force close

I picked my Nexus S up this am as the store opened at 9am. I powered it on and away it went it had all of my apps dl in minutes.I had to go into work so I just let it charge on my car charger. Got to work and went to start Cardio trainer ( which is an app I use daily for about 3-5 hours per day) it immediately force closed. Force closes each time I try and use it. So i sent message to dev. The next thing I know I get a message saying that Beautiful Widgets geolocation is getting false reading from the GPS and it force closes. The GPS has been spotty. When first initiated it took over 10 minutes to get a lock. Turned it off and tried again and it took 7 minutes. The third time it was about 15 seconds and since then it alternates back and forth from almost instant to minutes again. What concerns me is that the accuracy just bounces back and forth from 32.6 ft to 16.3 ft and anywhere in between and really never stabilizes. This may be normal for this type GPS systems(I don't know) Also I have the old market and cannot find a link for the new market.Wasn't Gingerbread suppose to come with the new market? So far I am impressed with the smoothness of the system but not with the GPS. Also the lInpack scores are lower than on the Vibrant. Appears to be very solid. Anyone else have any of these problems?

It sounds like a GPS problem with your device, Just get it swapped mate

I've only had FCs using the new google maps so far.
Random FC for me in maps, market and gallery :-/
ive yet to experience a FC
Cardio trainer is not working for me either, I am wondering if the dev's need to update it for 2.3, I also can't get vlingo to work.

phone randomly goes to boot animation screen
Ok, so it appears something is wrong with my phone. Every once in a while, i'll look down on my phone or in the middle of doing something, and it will go to the boot animation screen. Most of the time, the boot animation screen is dimmer than on normal start up. It will eventually go back to the ui, which I will then have to restart my phone because it won't connect to wifi or 3g.
Anyone else had this problem? Think it's worthy of getting a replacement from bestbuy or a glitch that should be fixed with an ota?
I haven't seen anything like this yet, though I suppose I don't keep my eye on my phone constantly, so I suppose it could have happened while I wasn't looking. No WiFi or 3G problems, either.
Sounds like you've got a serious issue there if you're seeing it a lot, though. I would get it replaced. Unless you're running a third-party ROM or some other non-stock mod, in which case dump it first and see if the problem is being caused by that.
Yea I had this happen twice. At gym was changing a track with Bluetooth headphones and went to dimmer bootscreen had to pull battery. And another time I had to reapply all my Widgets on my homescreen. I'm on CM7 rom

Are you using a custom ROM/kernel/SetCPU? Those problems sound like the ones the D1 has when it's clocked past a stable speed.

I'd look at the software you've added since the phone was purchased as the first primary suspect. Weird widgets, background services, live wallpapers, background syncing app, something like that...
You'd want to wipe/reset the phone before a return anyways, so why not do a factory wipe/reset from the settings/privacy menu, then start off with a fresh phone (software wise)? Be conservative in what apps you install at first, and check for stability; then slowly add back the stuff you'd have one by one and see which app from the Market causes the glitch.
I think that's a bit more fair to Samsung, Best Buy, and whoever ends up with the device as a refurb, than returning what is probably not bad hardware to the store.

Hmmm...and you don't think the fact that you're using ALPHA level firmware that is known to have some bugs in it, might be your problem?
I'd expect that kind of thing with CM as long as it's alpha, and even beta. I wouldn't be surprised with it even on the RC versions. It's experimental until Team Douche releases an actual ready-for-prime-time version.

Random Reboots, we call it on the SGS (samsung galaxy s) side
hoping for the best, it is not the same deadly problem we found on some of the 16GB SGS phones, that eventually lead to the corruption / destruction of the internal SD
but those were the signs.
so i'm really hoping that is not the same problem, else i'll really be pissed with Samsung to produce yet another crappy phone with cheap internal parts.
it should not be, as i saw pictures of the innards of the SNS (samsung nexus s) and it was clearly showing SandDisk for the 16GB internal SD
Random Reboots
A couple of times I've had the Nexus S reboot, once when I was in the middle of a call and once again as I was messing around with the settings.
I'm running 2.3.1, th latest build GRH78, does anyone have an idea as to why the random reboots are occurring?
Thanks in advance for your help

Make things a bit quicker - My experience

I've been trying loads of things to try to make things speed up a bit more with my rooted Bell Atrix running the new Telstra FW, and the 4 things I've found that seem to improve the UI speed that do not require rooting, are as follows:
1. On a fresh reset, use the Atrix to format both internal and external SD cards. For some reason after doing this on a fresh reset, it seemed to speed up the "instant on" when the phone is asleep and you press the fingerprint scanner on/off button to wake the phone. Of course, remember to back up your external SD to your PC prior to doing this.
2. Setting the Wifi to be always on (never sleep when its on).
3. Don't use ATK task killer
4. Don't use SetCPU
Even with all my apps reloaded, and loads of use over the last few days, I found these things to cut the usual 3-5 second wake time to between 1-2 seconds, and for some reason the general UI speed was much better (even using Blur)
I'd be interested to hear any feedback on people who are thinking about starting fresh and resetting their Atrix, and trying the above to compare to what they had.
I'm rocking the telstra with all the blur and bloat deleted not frozen. I deleted the browser because it doesn't let me download apps from the internet. I replaced it with dolphin browser. Deleted email and various other apps like car dock, etc. I underclock to 800 for screen off. I literally replaced every transition animation with an app from jrummy (root required) I use automemkiller to allow more memory for empty apps and honestly I have a lwp running and constant usage and I last 16 hours on a charge and use it constantly! Death to all lag.

My phone has never required more then a second to wake. I see nothing in the list that is even sleep related - and leaving wifi connected all the time is a battery drain.
Sorry, but i only see placebo effect.

If you are around Wifi more than not, it is best to keep this on "Never"... The Wifi uses way less battery than 3G/4G. Having your phone update using wifi will save battery for sure.

You must have one special Atrix . The only time mine wakes within 1 second, is within 10-20 seconds of the screen going blank. If its been sleeping for more than 1 minute, it takes at least 3 seconds to wake.

Help..battery dead in 22 hours on standby?

So I had my a500 fully charged Saturday afternoon. I go to turn it on and its dead. Something is wrong here for sure because I use to go a week on standby. I posted some pictures of what my battery life looks like. Its a straight linear decline and I can't figure it out. I'm rooted, and thinking maybe I'm trying to receive the 3.2 update and I can't due to be rooted. I checked system update and it says I'm up to date. Please, any help?

Check to make sure your Bluetooth is turned off, and your wireless is set to disconnect when screen turns off.

From the pictures you've posted it does look like something is up. Awake time is supposed to coordinate more or less with Screen On time. That's a general rule of thumb. Background things will wake the tablet and work very briefly sometimes but it doesn't look like that and generally takes seconds, adding up to mere minutes in total over days of that behavior. In essence awake time is supposed to follow screen on time closely with mere pips in difference. Yours is pretty much solid.
You could be right about the update, though I don't see how or why it would cause that anomaly, since it doesn't try to check for the update if the wifi is off, and even if the wifi is on it doesn't download it unless you tell it to. Plus, you can always turn off the automatic/scheduled check entirely.
Other issues I can come up with are net' related (stuck weather update, account sync, browser sync, picture sync, etc.) but are all invalidated since your wifi use is not that bad. I'm thinking any of these would trigger your wifi to stay on.
What's left, perhaps a rogue task manager? Something that's killing a necessary task which is then quickly restarted and so the loop goes on till your battery dies. If I can think of anything else I'll post it.
My only recommendation for now is to stop any task manager you have running, as well as locale or tasker if you have those. Restarting and then seeing how things fare after a day of standby.
i have similar situation.......
battery drain on my HoneyVillain 1.2 with Richard's Kernel is unbelievable.
It is not keeping even a half day. With Honeycomb 3.1 or 3.0 it was much much better.
What i see right now:
- on the battery usage graph i see that "Screen" is eating 80% of the battery - is it correct???
- when i'm at work, where my tablet is connected only to internal WLAN Network (no internet access) - the battery is going down much slower
What i have installed (and running in background)
- exchange mails (3 accounts - push method) with exchange widget
- simple calendar widget
- asus weather widget
- extented controls
- hacker's keyboard
looks like i got the same issue

80% is harsh but I suppose that could be correct, especially if you use the tablet a lot. Following my own tablet as an example, at any point in time my screen takes more juice than anything else on the tablet. I have my screen set to 40%. Auto brightness isn't as sensitive as I like it so it always falls to maybe 60% when I'm fine with it at 40% or so so I manually adjust that while at home.
My screen follows my awake time almost to a T.
Wifi also does seem to be eating a bit more than it did in 3.1 - maybe Acer increased the transmit/receive power in the chips so people stop having wifi connect/disconnect issues? Who knows. I've always had my wifi on 24/7 and overall it never took more than 10% of the battery from full to dying. Now it's considerably higher, 15% or more depending on how much I use the tablet.
But that 80% is still more normal than the awake time posted by the OP.
Have you tried turning down the brightness or adjusting the timeout? Indoors 30-40% is fine for me though I can go even lower, especially when I'm in bed or in the living room and the lights are off in the area. Outdoors I set it to auto or to 50/60% depending on whether I'm using it in my car or during shopping. Also, setting the perfect timeout can matter too. I set mine to 1m, but a really good practice is to set it to 30s and just set your browser or media player to keep it awake while in use. I'm too lazy to do those things
Neoprimal, thanks for the response! I just got home from work, and come greeted with what I suppose is the 3.2 update(~357mb). Now I don't know if that is my issue or not but it could have been. I'm rooted but stock everything. Am I okay to download this 3.2 update?

Quick suggestion.
Try changing ROM maybe it will solve your problem.
Neoprimal, thanks for your answer.
I reflashed my iconia back to 3.1 - honeyvillain 1.05a and i have no more battery drain issue.
Screen battery usage is as well at level about 80% so as you said it seems to be normal.
I tried as well other 3.2 cooked roms like taboonay or revolver port - everywhere i got unbelievable high battery drain.
So for me it looks like 3.2 issue.
You can be right with higher wifi power consumption in terms of better signal with honeycomb 3.2.
With3.2i had all the times all stripes blue - with 3.1 signall seems to bea little weaker but anyways strong enough for the internet.

Hey Proxonic, as you can see it can't be a '3.2 issue' because I'm on 3.2 and I don't have the issue.

I barely used my tablet this week because my wife asked me to 'break in' her Touchpad. The brand new one she got had a massive screen problem and we didn't discover it until days later because she never used it much during the week. Pray this never happens to your A500!
Anyway, this is showing that I have my wifi off when the screen is off - the screen on times are generally when I use the tablet to start music, usually before heading to bed.
Most of the awake time is the music playing, but some is probably IM programs and apps looking for internet. I use either google music, pandora/tunein radio/iheartradio or 2player Network Music Player; the radios and 2player NMP use wifi while I've cached a couple playlist or 2 worth of google music to the tablet. I also ran a test for another thread where person(s) reported their Acer Media app turning music off when the screen goes off, I suspect that'd be that long block of awake time without wifi.
Point is though, that I don't think 3.2 has a battery drain issue. Not in regards to while the tablet is sleeping/hibernating anyway. It sounds like maybe you just have some app gobbling up either cpu cycles or something else causing it.
Glad you at least got it fixed with the ROM though.
P.S The touchpad screen, btw looks like this...keep in mind, this is on a good day. When it got bad it was just a huge black block or tons of moving lines. Did a factory reset using Webdoctor and that didn't fix it. The replacement we got seems to be fine so far. The picture's really bad, sorry - took it in the car at a shopping center.

I have the same issue I am 100% stock on mine and ever since the 3.2 update i will have it fully charged at 8am and at 8 pm I am down to 20% and i never touched it the thing just sat in my bag while I was at work. and i have a 100% uptime. I don't use task mangers and have no idea what is draining it.

That definitely sounds like a rogue application.
Any app in your accounts and sync section has the ability to cause that sort of uptime, so take a look through them. Force a sync and go through each of them to see if anything gets 'stuck' syncing. Twitter and Facebook are always suspect, especially if you're 'busy' on them (meaning you have lots of tweets/facebook posts to sync).
Furthermore, the system is SUPPOSED to close away/sleep some apps after they move from foreground to background however, some of these apps can become locked for some reason and not close (thus the definition of a rogue app). Running processes, etc. may do this. So in addition to programs found under account and sync; any app that plays media (video or music) or connects to download data (news, social apps, shopping/deal apps) can cause this sort of uptime.
I know it can be frustrating but the fix may be as simple as removing the offending app.
Good Luck.

ICS in Note
After upgrading to ICS via kies,
Battery seems to drain very fast.
Camera hangs up sometimes and other camera related apps like Instagram also but maybe the pic quality is little better.
It seems to crash when some other apps runs too.
Not sure if it was there before but I can pause music and video if I show my palm on the screen.
The screen rotates faster than in GB with a pause at the beginning though.
News fonts are good.
Window animations are good but still dont' know how to stop it since it might be draining battery fast.
Can use Chrome now and it's fast.
I cannot use Mass Storage Mode. I recieve a "Ui stopped to work" error.
I am facing,
1. High android OS usage. Sometime its higher than Brightness, and most of the time its highest usage of batt after brightness. (I read somewhere, it said its calculation errors, but I think its not, cause my battery no longer last that long.)
2. Camera will sometimes fail to operate. I really dunno what is wrong with that.
3. Phone just cant go into deep slp. Its being kept awake by some apps (Which I cant narrow it) Using BetterBatteryStats, I found out its I2_HSIC. (Whats this I2_HSIC ??)
I am using a 5400mAh mugen batt. previously on GB, my usage can last me 24hrs, now it can only last 16hrs or less. I installed lesser apps, and lesser widgets. Disable account sync and google backup. Settings more or less kept the same.
Overnight my batt can reduce by 21%, it never happened before. lol. ICS...

I can get the screen back by just waiting it out. Usually takes about 2 minutes. I sure do wish I knew what was happening, though, so I could confirm no damage was being done.

1. High android OS usage. Sometime its higher than Brightness, and most of the time its highest usage of batt after brightness. (I read somewhere, it said its calculation errors, but I think its not, cause my battery no longer last that long.)
2. Camera will sometimes fail to operate. I really dunno what is wrong with that.
3. Phone just cant go into deep slp. Its being kept awake by some apps (Which I cant narrow it) Using BetterBatteryStats, I found out its I2_HSIC. (Whats this I2_HSIC ??)
I am using a 5400mAh mugen batt. previously on GB, my usage can last me 24hrs, now it can only last 16hrs or less. I installed lesser apps, and lesser widgets. Disable account sync and google backup. Settings more or less kept the same.
Overnight my batt can reduce by 21%, it never happened before. lol. ICS...

As far as #2 goes, go to your battery stats and see if "media" is listed. If so, force close it and try again. Seems to work for me. I'm not sure if it is just me or not because I have been playing with settings lately, but the media scanner tends to run wild it seems (also seems to lend to battery drain).
I am just disappointed that they left out some of the nice features of ics like the updated gallery and camera. Seems kind of lazy to me and no wonder things arent working well if they are mix and matching gingerbread and ics rather than going all in and starting development from there. I would definitely go back to using one of the non tw ics roms if it weren't for the sod issues I was having...

Iam not yet experiencing any bugs under heavy LPF usage but I agree they should have let us have more of ICS like wit the gallery

Indian stock Rom:
- Battery life seems to be strange as sometime drain is too high and sometime i feel it's better then it was on GB. yet to track the exact pattern but in either case no wireless, no gps, no Bluetooth and Brightness @ 10%.
- opening contacts taking few seconds but now search on exchange server is well integrated.
-i have enabled 'face unlock' and sometime it will not respond at all so keep doing lock/unlock till get restored.
.......and I am unable to find s-note application, i tried under system/app as well but as don't know apk name not sure. can someone help pls.
me too
I also got that green bands screen you describe. I held down the lock button til the phone rebooted. I think I was using the Dolphin Browser at the time.

I have a bug I have not seen mentioned.
Occasionally, usually about 1 time per day, My phone display will start to flash, with random green and red colors. The screen I'm on, will flash those colors then star to shake and slide.
It looks like a television station not tuned quite right on an analog antenna (if anybody remembers that!)
I can't reproduce it regularly, but It think it has happened when going from an Application, back to the home screen using the home button.
I am on ICS, Taiwan, stock, not rooted.
Anybyody else seen this?

1. Poor battery.
2. Sync errors: calendar sync freezes up every once in a while
3. Brightness slider in notification bar gone, tasker can not effect change of brightness anymore, only choice is to keep automatic brightness on, otherwise blinded out in sun.
4. Contacts and phone apps show up in 5s or more to load: need to switch to those ugly dialers, no choice at all
5. No widgets menu in app drawer as in nexus ICS
6. Launchers freezing: tried both nova and apex: many a times the screen went blank for a few seconds after hitting home (didn't crash though)

WIFI LATENCY ISSUE After the B08L update

Has any one noticed the latency of the WiFi radio after the update,
i sent back my first 6P because i figured it was a bad radio.
Negative it was the update
Test for it by doing this:
Launch play store with with the Cell Radio turned off, and watch the load time on the icons for everything, under NORMAL operation they should be bullet fast and when you scroll to unloaded apps it should "almost instantly propagate"
IF it takes more than 2 seconds obviously you are having the problem as well.
Try this in reverse with the Cell on and WIFI off. On cell it will be bullet fast
I dont know why no one has found this bug yet
I think they M build fixes something with wifi but don't hold me to that 100% I remember reading it somewhere if I remember correctly.

I don't notice any latency with the Play Store, it loads in a couple of seconds, and I have a pretty slow internet connection. I experience some pretty bad issues with Chrome though, it won't load pages at all sometimes, I mainly experience this on XDA (in saying that though my Chrome usage is 99% XDA).
Still Latent as all hell, i counted a good 20 seconds before it started to download the speedtest.net app. this is really starting to piss me off
Mine doesn't seem to have any latency but my WiFi DL speeds sit around 170-200mbs with my AC5300 router. I don't have any issues on slower networks either running the M build.
im going to flash the first factory image and see if that does it
ill report back
I had this issue and it was super frustrating. The Play Store wouldn't even load unless I switched it to LTE.
Turns out 6.0.1 fixes it!
