Wlan_wake in Better battery stats

Hi all,
So my phone recently started giving me some battery issues that I just cannot for the life of me get resolved. I noticed that under better battery stats, my phone was avoiding deep sleep. Looking at the kernel wake locks shows Wlan_wake with nearly non stop wakes. I've done just about everything. I've wiped totally to stock Blu Kuban, tried different radios, kernels etc. I get these even on a fresh wipe with no apps installed and no sync on. It doesn't seem to be related to any application in particular. If I turn off wifi and just use 3g,the phone goes into deep sleep immediately and stays. The Wlan_wake stops and the wake counter doesn't keep ramping up. The phone once again gets great battery life while sitting idle. This occurs on both of the wifi I use predominantly, home and work. I'm really at my wits end since when I go to bed, my phones battery gets knocked down a good 20-30% in the 7 hours I go to bed. Attached is just a small sampling of what it's doing.
Any thoughts or suggestions?

Stop leaving your WiFi on. Either that or install one of the hundreds of battery scripts available that will shut off WiFi when the phone sleeps.

While I can appreciate people who want to hamstring their phones to save battery life, turning off WiFi is not an option for most people who actually use their phones for grown up things.
Sprint data is horribly unreliable for me... Without WiFi on, I would never be notified of important emails from work, done of which are time sensitive.
It's too bad that ICS has such bad battery life when compared to a similarly configured GB device.

Well a grown up would solve the problem by calling Sprint and having a free mini tower sent to them so they wouldn't have that problem... just sayin

Is there some specific reason you can't charge your phone while you sleep? It seems like that's the most obvious and easiest solution to your complaint...

I'll take a look at that wifi idle time thread, thanks man.
To the rest, when I suddenly have a glaring issue with my phone, I usually don't include "pretend the problem doesn't exist" as a troubleshooting method. If that's what has to be done, so be it. Charging the phone while sleeping is fine, depending on my schedule/battery level, but that doesn't answer the question of why the battery is absolutely horrific when the phone is doing absolutely nothing. It's not syncing, it's not pulling down data from apps etc. I guess I'm just having trouble coming to terms with the fact that Gingerbread idles, with sync on, about 3-5 percent in an 8 hour period (on blazer) while my ics experiences have been literally 10 times worse. It's hard to just say "oh, ICS battery life just isn't as good", when the disparity is that large.
I want to make sure I'm an exception, not the rule as far as idle drain is concerned.

Since I'm included in the "rest" ill say that I was not suggesting that you ignore it, I was simply suggesting that by charging while you sleep you would remedy the issue for the time being, as there is absolutely no logical reason your phone can't be charging while you sleep... including battery level... im assuming from your post you wait till the battery is low to charge, that is unecessary as Li-Ion batteries do not have a memory, so incremental charging will not damage them, in fact ive read that its actually better for them than full power cycles.... if you want more possible solutions perhaps you should start by following revampers link and using the damn search bar, as there are 10's of ics battery threads, and I'm pretty sure phaker posted a solution to a very similar issue in one of them, as opposed to starting yet another thread about an issue that's been beat to death and replying condesendingly to those who offer you suggestions not entirely to you're liking....also use the thanks button at least for revampers post as you seem to have found at least that useful, its considered common courtesy around here...

You weren't included in the rest btw. Forgot to thank v.
The first response was snide to both myself and the other person who replied about slashing off your phones arm when it isn't necessary. I have spent quite a bit of time on this problem, and have done substantial searching with my info I've collected from various apps and logs. Snide non replies get snide responses. It was not aimed at you.

This may help as well, worth a read at least... the script that just modifies wifi_supp_scan or something to that effect.... should be what you're after as I recall that was preventing deep sleep, read through the thread to confirm, I read it about a week ago and dont recall 100%

[Q] New GS3 vs GNex, getting very poor ping

When I had my Galaxy Nexus I was regularly getting pings of 80-110ms and 6-10MB downloads.
Just got a new T-Mo GS3 last night from the T-Mo store and all pings have been OVER 1000ms with around 5-6MB downloads.
Both phones were/are on the $30 Prepaid plan (100 mins, unl/5GB data & unl text). Only the phones have changes. Always testing from the same location. The download speed is fine even at 3-4MB it's the pings that are killers. Testing with Speedtest.net app so whether the tests are accurate or not the comparison delta should be valid.
Any changes that need to be made with the prepaid plans?

I would try flashing a different radio on it and see if that helps. Some people have better results using different radios which perform better or worse depending on which area you live in.

Read through my thread and you should be able to understand whats haooening a bit better.
In a nutshell, your ping times probably aren't going to matter as much as you might think. Reason it happens is because at idle you are on a slower connection and when you begin data transfer it takes a moment to jump to 4G.
As soon as the test finishes immediately retest and youll probably see that ping time go down.
Also make sure your using the same server. And toggle airplane mode on/off on both phones before testing.

Thanks .. it seems to have improved today. Maybe it was a local issue.

Usually is a tower issue. Especially if all you do is test one time and blame the phone immediately.

I agree, however the tests on the SGSIII was run multiple times (dozens) over 24hrs.

Defective Radio?

I have been having a lot of problems with my new honey, namely in the signal department! I went through a whole thing with it right after activation...it worked, then didn't, then did...etc. A chat session, phone call, & 2 trip to the actual store (all in 1 day!) resulted in them doing a factory reset and sending me on my looney way. It seemed to have helped, for about a day and a half. Now it is dropping signal again! It seems to do so, sometimes, when I have the wifi on. But then sometimes not (I'm not sure if wifi is culprit or coincidence.)
The ATT store employees said I may have changed a setting (I'm sure I didn't as I don't know of any setting that would even cause that!) and also "explained" my signal will naturally fluctuate...(They think I am an idiot, obviously and of course the phone was working fine when I was there...duh!) They also gave me a new sim card.
I *really* want to love this phone! But I'm finding it frustratingly undependable. Texts won't send when I need them to. I'm not getting them either, always. Voice is hit or miss when it drops (sometimes it works, sometimes not.) I have ALSO noticed the signal is not as strong as my old beloved Cappy. That thing was a horse (and I'm thinking of going back to it if this new one doesn't wise up!) Seriously, $300 bucks for a brand new phone & it can't keep a proper signal?
Is it the radio? Is it the software (still 100% stock, unrooted)? Should I make them give me a new one? What if it doesn't work, either? Flashing it to fix the issue is fine for me, but I've been holding out for multi-view before I get flash-crazy. lol Not to mention I may have to return it so better to not mess with it [yet]. I'm very frustrated & tired of getting looked upon like I'm the typical woman idiot who is not as smart as her new smartphone!!! I am NOT imagining it!!!

Sounds like your antennae is shorting out or something like it wasn't soldered properly or the cable isn't secure. Would explain why WiFi affects it. I'd go there and demand a replacement and if they don't wanna budge your within 30 day no questions return. Then go to a diff store and get a new one. I really don't see it being a software issue.

Is it possible that whatever the problem was, it miraculously resolved itself? I had it drop signal two more times since this post, then nothing since. It's been working perfectly. I hate to keep it if it might arise again but I hate to return it if it was some weird fluke thing.
This may or may not be related to the above problem: has anyone noticed their reception is not as good as on a previous device? I had a Cappy and it always got great signal. I noticed this one is not as strong in the same places I previously visited with my old phone. Although admittedly, it seems to be improving. Does that even make sense or is even possible? Just like me, my phone has to be the goofball of the bunch!

Nope. I've done nothing because I'm having this returning debate. lol I'm itching to though!
This is classic "my car doesn't work so take it to the garage then it works fine and they will make fun of you" If I do return it what do I say? It is documented about my "troubles" as per the ATT phone rep. Though if I can't reproduce the problem they're just going to send me on my way, I'm afraid.

You spent enough money on the device, you should be absolutely happy with it, not apprehensive. If you wait past the return date, it's going to sit in the pit of your stomach for 20 months and ruin your enjoyment of it until you can upgrade again. Not worth it. Smile your brightest smile, walk into the store, very nicely tell them that you've had multiple issues and the AT&T phone reps said to go in and ask for an exchange. That's it. They're going to count on you being intimidated and going away. Smile, be nice, and don't be intimidated.
If they say you have to reproduce the problem, invite them to spend the day with you. The Note 2 is amazing and you shouldn't settle if you believe your hardware is having problems.

Yes. I have decided to take it in later today, as my 14 days is up on Friday. I hope they have stock of them. Anyhow...I have another question. If a phone is sitting still with no movement (and the weather is good, lol) will there be variations in signal strength? I get 3 bars with 4G showing, then it drops to one tiny bar. Sometimes the 4G disappears then reappears. The it will go back up to 4 bars. All in the course 5 minutes! I do realize signal will vary with movement but will it if your phone is just sitting there?
I am trying to experiment a little. I just realized/remembered that I had (uneventfully) dropped my phone (not hard, in-case) about the same time as my dropped signal problem pretty much resolved itself. So then I was like, hmm, maybe there IS something loose inside. I've tried gently shaking/jarring it here on my desk, coincidentally with the bars dropping back to just 1 as a result. But then again it may be coincidental as they are seeming to waiver A LOT. I just wondered if it is normal.
I never really stared at my old phone (Galaxy1) here at my desk but I'm almost positive it always had more than 1 bar at this same location and I never noticed it waiver like this one. But like I said I never had to make myself stare at it to check, either! lol Just wondering if someone knows a little more about cellphone signal 101 than me.

I have the issue of no 4G HSPA+ but I can get a strong LTE signal when in an LTE reception area. I'm wondering if you are in an LTE area and can get LTE? Where are you located?

I have noticed problems with my GN2 as well. Mine shows I have signal but my data stalls or doesn't seem to work as it should. I'm in an area where there shouldn't be any problems. Only seems to happen in non LTE areas. Whenever I have LTE signal this thing is blazing fast.

Update: Took the phone in. Basically, they had never heard of the issue with this phone. But...I walked away with a replacement. So far so good though I've had it only a few hours. The girl was very nice & explained even though I was borderline limit she would take care of me. I told her I received it Fri the 9th but she said they were basing the 14 days on the 7th! I said I didn't physically have it till the 9th! Jeeze. Moot point since she was going to take care of it anyhow but it just concerned me how (corporate) att could chop 2 days of my in-store return time!
So no, I'm not in LTE land, unfortunately. 3g H+ & E only though I can't complain about the coverage or speed. Good enough for me 4 sure.
The signal bars waivered quite a bit even while in the store. They said while some fluctuation is normal it shouldn't be as much as it was doing especially with the close proximity of the tower & good weather and especially while just sitting on the counter.
I downloaded the free app "No Signal Alert" from the Play Store. In just a few hours it recorded lost signal 4 times! (In a very good coverage area) [my first phone b4 the exchange] Consider using it if you want to see if you are losing signal like I was. Handy app!
Hopefully this is a good one. I know it sounds goofy but this phone seems to even move faster than the other. Weird. It will be interesting to hear if anyone else is having this problem. Maybe there was a bad batch of them or something? Like the Nexus I read about & their signal problems.

I have a similar situation with mine. LTE will be working fine but then I notice that once I connect to my home wifi and then either leave my wifi range or turn off wifi the LTE icon will show in the status bar and it will show that it's sending and receiving data but Web pages will stall and never load, Play Store will timeout, and SpeedTest.net will start up but the needle will freeze about 1/8 of the way up indefinitely. I've toggled data at this point but it never fixes it, I have to restart the phone at which point LTE works perfectly but once I get back on my wifi the cycle will repeat, this has happened reliably for about the past week.
Do you all think I have a defective radio or am I missing something? I'm still within my return Window and will probably swap it Friday.

That's exactly how it's acting for me. I just now disabled the AT&T Smart WiFi app and after a quick restart and toggle test there was no problems, but I'm not sure if the problem will only pop up after I've been on wifi for a while. I'm going to see if it keeps doing it tomorrow.

Disabling Smart WiFi appeared to fix the problem.

What I noticed today is that when this same issue happens, with 4G icon and wifi icon both active, it occurs after I manually check for a firmware update within the system settings. The 4G icon doesn't go away until I reset the phone.
Also I manually deleted the all the AT&T boat ware apps before this was happening so the smart wifi app is not causing this for me.
Sent from my SAMSUNG-SGH-I317 using Tapatalk 2

Weird, if you get the issue and don't have the Smart WiFi app then it must be something else and it was coincidence that it worked normal for me today. I've only checked for firmware once (when I first got my phone) so it must be something else causing it. I'm hoping the multi view firmware will also have a fix for it.

4G=> Hot Screen/Fast Battery drop/Other?

I"m on the ROM per my signature. My home is not in a 4G area.
Last night I was in a 4G area, and not sure if what I experienced is expected; or if not if it has to do whith my ROM>
First off, I lost data connection and had to reboot in order to re-establish connection to data, a couple times. I also found that my screen more so than the back (with a think battery) got quite hot. I also noticed the battery dropping quick.
I suspect a possiblity of poor signal where I was at. Did not make any calls. Now that I think about it, the signal bars was not a full 4 bars.
Just wondering what others think.

I also would like to say I'm experiencing the same issue. My battery is much better now only because I turned off LTE. Just a temporary solution. I'm gonna follow this thread to see if anyone can help.

Well, I was up in a different area last night that had 4G, and I had 3 bars. The phone battery did OK, and I didn't have such a hot screen. But it was New Years Eve dance, and I didn't take time to try to communicate over Internet.
But it leaves me feeling that my issue was that the 4G was not good coverage where I was at before, May be a while before I"m in the same area. But I'll keep updating as I experience different 4G connections.

[Q]4G data speed very slow during call

Hi, I have a galaxy S3 with T-mobile. I'm in a place where I have excellent 4G speeds (about 5-6 Mbps :speedtest), I noticed that when I'm on a call the 4G data speed drops to useless speeds. I can barely open a website or download an app. Speedtest shows like 500+ ping and about 500kbps download which is NOT constant (goes up, stops, goes down, etc). Real speed is way less than that. Websites don't open or take forever.. Is this normal? I am using stock rom (but also happened with other roms). I went back to stock thinking that this was a problem with other roms only, but the same thing happen with stock rom. Any ideas/clues/solutions? thanks in advance

Long ping times is normal due to how it operates. But only 5-6mbps? That's pretty slow. Most get averages of 13-18mbps and some get averages around 25.
Try the different modems to see which will be better for your location.

So, its kind of normal to get slower speed while on a call?

It would seem a logical conclusion. But I've never tested it. But I've never had anything not load or go slow enough for me to notice. If I think about it on my next call ill try to test it out.

Ok thanks, The problem here is that I find it way to slow.. lets say I'm downloading a file with no phone call going and I get 600KB/s, during I call I get like 16 to 40KB/s at most... It's like having dial up again... way to slow.. I think something is not right but can't figure out what, since I reverted back to stock wiped everything and also formatted the system after installing stock..

Have you checked your imei or ever lost it?
If not you should really try the different modems.
If this is a recent development you should also call support to see if they have any tower issues in your area.

IMEI still intact, and have never lost it. I will try with different modems thank you! I'm not sure if this is a new issue since I didn't use my internet as I am using it now while on a call before, also I moved from Puerto Rico to the states for a few months, so there are many variables at the same time. But will try with the modems.
Another question, when I odin Stock (not rooted) ROM does everything (incl. modem, kernel, etc) goes back to stock?

Good luck.with the modems! It takes patience, but is worth it in the end!
Yes, Odin flashing the official firmware will set everything back on stock.

Hello, spent the whole day testing out every single JB modem from your post and none of them solved my problem... did find better speeds with some on them while not on a call. But as soon as I'm on a call the speed drops to about 47kbps, looks like a cap or something because I get constant speed of 47-49 kbps. Sometimes it goes over the cap and works normally but for a few seconds then the speed drops and its not constant anymore until it reaches around 47kbps... This is so frustrating... is there anything else that I can try out??

Flash the LJC firmware package. Third firmware link in my signature. This is for SGH-T999 (d2tmo) only. Unsure about the download cap while talking on the phone. Aren't the two separate? Cell and data, right? Shouldn't be a cap then, but I've never been talking on the phone while downloading a file. I will try it if I think about it tomorrow.
5-6Mbps is not bad. It just depends so much on where you are. My fastest test ever was the other day @ 14.4Mbps. It's not a big city, but it's sizable. It's usually under 10Mbps in that location. And normally less than that everywhere else in the area. There are some areas that put me on Edge. Might as well just turn on airplane mode. Because T-Mobile's Edge... is actually worse than no data connection at all.

Thank you, will try that tomorrow. 5-6mbps is fine for me but that is without call. While on call is like 0.37mbps constant or really bad ups and downs.. is like edge (worst than not having connection at all).. anyways will try and report back. Thanks again

Sorry I couldn't remember this before, but I have a theory that could explain what's going on there.
Voice calls and 2g (GPRS) both share the same frequency spectrum. I remember doing some 3g research in the past and one of the benefits to the introduction of 3g was more overall bandwidth for all, even those left on 2g. At the time, 2g data service was greatly impacted by how much voice traffic was going across the network at any given time.
During peak voice call times, there was less bandwidth for mobile data users because the tech was designed to give priority to the calls. This meant even slower than usual 2g data speeds.
But as people moved to 3g, there were less using 2g for data lessening the impact caused by voice and sms communications.
So what I'm getting at is when you are on a call, that call is going across 2g frequencies, meaning you are connected to 2g. (Though 4g data should still be available to you regardless. But it may have something to do with what you're experiencing.)
Keep in mind that this was 3 or 4 years ago. I'd think that it'd work differently now. But it is possible that they never changed the fact that voice shares its spectrum with 2g. I could be seriously off with all of this, but I still thought I'd mention it since it would make a little sense with the speeds you're seeing.
The thing is, the S3.is capable of using DC-HSPA (dual carrier) which means it can use 2 different signals at once (one from T-Mobile, one from a partner carrier) for greater speeds (HSPA+42). So I don't understand why it won't use this same tech to give you better data speeds while on a call.
I know I've used mobile data while on the phone before, and never felt like the qos was lacking. But I never speed tested it either.
The more I think about it though, the more I'm thinking it's either firmware (see aerowinders post above), hardware, or you're connecting to a tower that either has problems or hasn't been upgraded in a long time. I don't believe that what you're seeing is normal operation.
Of course every bit of this is speculation at this point. Hope no one thinks I wasted their time with it. I thought it may spark some ideas though!

I was looking up some information and ran across this. Figured Id link you to it since it is directly related to your problem.
You can pretty much ignore my above post! LOL
T-Mobile Support Document - Using Voice and Data Services at the Same Time
Basically, it looks like you should call Tmobile.

Tried with the file you provided and still the same results.. I guess I will have to call tmobile to troubleshoot this problem :/ thanks tho

Hello, I still have not called customer service, but I'm going to be back where I din't have any problems next week. I'm going to test it out there. If I don't have problems there, then it's this area the one with problems. Anyways I will let you all know my findings.. Thank you all for the support!
Edit: I just confirmed that it works perfectly fine where it used to worked fine. It must be the new area where I moved recently that has issues. Thank you all for your time and help.
