[Q] Multicast Filter - Verizon Samsung Galaxy Note II

I have been chasing a wlan_rx_wake on my phone since I have moved back home. I am guessing this is because of the multicast on my router, but living in a college apartment I don't want to think about messing with it too much. The reason I am doing this is to improve my battery life as it is around 22 hours right now, which is lower than what I initially was getting with the phone.
Anyone have any ideas on what to look for or if there is a kernel for the verizon phone with a multicast filter? Thank you.

Care to explain multicast? I got that wake lock often with my gs3

Honestly, I don't full understand it myself nor feel confident to explain to another person. I feel that it is a part of my problem, but for the time being running better wifi to take care of things for the time being. How I have it setup, when the screen is off 30 seconds afterwords the wifi is shut off. Lose connectivity, but battery life goes up. I am willing to lose connectivity for battery life at the moment.

I don't get it all the time. It's weird others and my googling have basically said its a router issue with it waking the phone up but this is the first I've heard of multicast. That's why I asked

Want to do an experiment (Please Read Edit 1 if participating!)

I want to test a theory guys. Anyone else who feels they want to be a part of this feel free.
This is what I want to do. I want to test the actual draw of the screen in a normal days use over 2 days. The first day set to ~25%, the second day set to 75%. What I want to see is how many minutes at those brightness the screen was on. And the difference in the usage on the battery on those 2 days.
You don't have to be dead on with your estimation of time the screen was on, but try to be within a few minutes. If there isn't much of a difference then I believe the screen actually is pulling power while "off" and killing our battery unnecessarily fast.
There is no reason on 12 hours of battery, with screen on less than 30 minutes total that it should consume 65% of the battery! I don't actually see my battery drain 65% right before my eyes while it is on, so something has to be happening behind the scenes.
Edit 1: Post a screenshot of your results from both days. Tell me what connection type you used through the day. What ~% your screen was set to on both days. I only need the screen percentage changed, as long as everything else is consistent it is irrelevant to this test.
Day 1 do a low 20-30% brightness, day 2 do a high 65-75% brightness.
Edit 2: I just realized that when under battery use you can click the specific process (here being Display of course) and it will give you the exact amount of time used by the screen. If you guys could, please post both screenshots, as well as give me the accurate amount of time the display used battery.

I don't know if you ever had the original Dinc (I see an Inc 2 in your sig) but on stock ROM that phone constantly reported 60%+ Display usage no matter what you were doing, even lightly used. I crank my brightness down to like 20% permanently. I don't use it outside, so I don't need it super bright. Did it on the Dinc, and I'm doing it with the Rezound. Usually see display around 30-40% unless I'm using it heavily.
And it's not consuming 65% of the entire battery, that is 65% of the total drain is attributed to the display. SO if your battery has gone from 100 to 90% in 30 minutes, and 65% of that is display, your display has drained 6.5% of the total battery.
This is why I said over a day dude. I didn't say tell me what it says right now. If you don't want to be involved in the experiment don't bother posting in this thread. That goes for everyone. I stated 65% of the total consumption. If you really think I am an idiot don't waste mine or your time posting because you will just piss me off and I will report your posts.
If you had read the post correctly you would understand that I get 12 hours or less of battery life while only using the screen for maybe 30 minutes out of that 12 hours. Yet it reports 65% of the consumption is due to the screen even on 20% brightness. Theoretically that means I should be able to use my phone screen for 30 minutes straight and should be able to watch my battery drain 65% in that 30 minutes, which it does not. Therefor there is something else pulling power either stating it is the screen, or the screen is drawing power when off.
Hostility unwarranted. I misread your post, simple explanation.
I'll try cranking my brightness up and see what I get over a day of moderate use, how about that to make up for it?
Lol, Sorry man, I haven't seen you post here before. There are so many members who just post to post. Everyone has their 2 cents, you know what I mean
Appreciate it though!
I'm willing to try this. I'd have to start tomorrow. I also have a few basic questions.
1. How are you estimating time screen is on? Is there a way to do it other than just me paying attention? Cuz that's hard for me.
2. Does that stats page need to be reset at the beginning of each day? Also, where the hell is that thing? I've been to every setting on this phone exploring it and then when I want to find something again I can't!
3. Does it matter what power mode the phone is in?
And I was thinking to add to the test it might be interesting to see what having the screen on "automatic" would do.
1. I don't know of a surefire way, if someone else knows let us know! Otherwise, just a rough estimate is fine 30 mins ~35 minutes really. As long as you don't overshoot too much.
2. You don't need to reset the stats, they do it automatically after being on the charger for an extended period. So if you charge overnight and take it off it will only show from when the phone was disconnected. Settings >About Phone > Battery >Battery Use.
3. Power mode should have no relevance. But I am using "normal".
You're going to have to specify if WiFi or 4g/3g is to be used. I have noticed over the past few days that 4G consumes roughly 1.5-2%/hour less battery than WiFi does. On my Dinc, WiFi would draw a lot less power over time than 3G, but not so with the Rezound. So now I leave it on 4G while it sits idle at work unless I need to download something big, in which case I'll switch to WiFi, even though I have unlimited data and technically don't need to care lol. But I found that with WiFi and 4G both on and WiFi connected, my phone was burning like 5.5% per hour of battery. With 4G on only, I'm going through ~2.5% per hour (these are both with the phone sitting idle, usually in the morning when I'm busy at work). That's pretty much what my Dinc was doing on Wifi. I'll have to try it sometime with WiFi only on, and 4G off to see what happens.
But regardless, please specificy WiFi or 4G. Any testers that volunteer for this will need to leave that connection on as their sole connection during the duration of the test, save for a few mins of variance here and there.
Doesn't seem that should affect how much power the screen itself uses though. He just wants to test screen battery usage, not overall battery usage.
EDIT: Oh, if we are talking percentages then yes, it would matter. I generally leave my phone on 4g unless it decides to turn it off. And I switched to wifi a bit ago since I was required to to download an app from Amazon.

You are describing exactly the opposite of my experience with 4G vs WiFi battery consumption.
Hmm, interesting. Maybe I just have really good 4G signal? I too thought it was weird, given my experience with the Dinc being exactly the opposite of the Rezound. Trust me, I'd love to know why it happens that way too lol. But again, I shouldn't care because I have unlimited data, and the 4G is faster than the WiFi here at work and about as fast as my home connection (I average on the lower end of the 4G scale, about 10-15Mbps), so I'll probably just leave it on 4G for now unless I'm at home and need to FTP to my laptop or something.
And feralicious, I agree to an extent, but to get truly accurate results we at least need to know what X person was using for data over Y person, since both connections will draw power at a different rate. The only other accurate way to do it would be to keep the phone in airplane mode. And since he's using approximately 5% per hour of battery, whereas I'm using 2-3%, maybe he's on Wifi where I'm on 4G. As in any testing you need to have a control along with the variables, and the data connection is a big variable that could easily be made a control. Just my $.02

Yeah, I just realized that and edited my post, didn't see you had responded.
For the record, 4g seems to pull more power than wifi for me as well.
Just post a screenshot of your results, tell me the amount of time your screen was on, and what your primary connection was. This is the only info I need. Your connection will only minutely affect the percentage that the screen draws. I only want to know the difference between screen high and screen low. So long as everything else is consistent on your end your results should be accurate for what I need.
Looks like I have to extend it out a day. I set my phone to 75% brightness and go figure it is the day that the network is having outages. My battery lasted ~2 hours today doing nothing.
Wow. 2 hours?!?! Will start the official test tomorrow as well but for the record my screen was also at 75% and I got almost 10hrs and I texted, shopped for and played with apps and watched a few app videos. I turned on wifi for a few hours due to network outtage.
Posting results even though they're not considered official. My screen was on approximately 1-1.5hrs in my estimation.

lol I woulda been in the same boat, if I didn't have a coworker alert me that 4G was out. I hadn't looked at my phone all morning, and woulda had a dead phone from it constantly looking for a 4g signal.

I had no idea, my phone was in my pocket and I was busy all day. Never felt it ever get warm, pulled it out of my pocket when I had some down time to check my G+/FB/Twitter and BAM.. phone wouldn't turn on. Luckily a friend had a charger and let me hook up. Turned on the phone to see the battery had actually died. I took it off the charger at 11:30 and it was dead before 2.

Thanks, I will be trying high brightness again tomorrow.
I couldn't get a reliable test because I had a stupid setting left over from my experiment with Economy mode that turned WiFi off after 15 minutes, so my data is skewed a bit from the first day to the second. (Plus the roving 4G outages caught me last night and my battery went from full to 5% overnight.)
Also, I use an app called SystemPanel (bought the Pro version) which gives me nice plots of my usage and screen on time, if you're interested in more data like that, you could look into it.
I just realized last night if you click the process in the battery use window that it will show the time that process uses power. Soooo.... I need everyone to start from scratch and give me the accurate amount of time the screen shot is on, for both dim and bright settings. Sorry guys! OP updated.

Second rezound still getting toasty... Opinions?

So, i will make this blunt... This non overclocked phone gets hotter than any other mobile device i have tried...
I am already on my second one, after number one hit 125 while sitting on my desk. This one has hit 114, which is still unacceptable really, since the room is climate controlled to around 74...what happens when I use it in the summer??
Now, by virtue of need (infrastructure tether) , I am using the ICS beta, but I cannot believe it will effect it that much. I have a 3.7v battery, so that should be good.. I will admit that I am in a building that does not do well for 4g, but frankly, my phone burning itself up just searching for a signal is unacceptable as well...
I am about ready to throw in the towel and try a GNex, even though its radio problems scare me too...Any advice guys?
what apps are running, also is this while it is charging?
Just want to start with a big thanks for all of your work over on the nook boards. The overheating has been an issue since the start. I am on my third because of it. I only reach high temps when playing games. I can stream movies all day long, and never get over 110. I am waiting for an aftermarket battery that can handle the drain from this beast phone. I guess it depends on what you will use your phone for. Glad to see you here, and hope you stay. Sorry I couldn't be more help. Good luck....

Most apps won't affect temperature in any real way.
Tethering requires broadcasting wifi signal, and equivalently large wifi broadcast (broadcast SSID, and all data) at an equal speed to the ultra-fast 4g.
Now, this 4g phone (as well as ANY OTHER LTE PHONE RIGHT NOW) will overheat if you download a 300-500MB file at a fast 4g speed (like 25 MBit for instance).
Overheat. Untouchable.
Wifi tether (even on 3g) will overheat a phone if you're using a decent amount of data (rather than using it for short bursts).
My HTC Eris, I had to leave the back battery cover off, and put a cold can of soda (with a paper towl in between to stop moisture) to keep it from overheating.
The Rezound will get so hot that you literally can't touch it.
Charging WHILE you tether will make it a lot worse, as the chemical activity within the battery (to charge it) is going to increase heat. Add that to 4g cell phone connection, and the wifi antenna getting hot broadcasting, and you've got a 125 degree phone (which IS hot enough to start breaking solder points).
If you have it OFF the charger at that temperature, you will notice that the notification light is now flashing orange/green back and forth. This means that the unit is overheating and should be shut off, immediately.
Get the extended battery to hang out and wireless tether for a while. It generates a whole lot less heat if not on the charger, and seems to (maybe due to the case that has more space for air in it) not heat up quite as much, in my experience.
Tethering can overheat your phone. 4g can overheat your phone. Add charging to that, and it doesn't matter how many rezounds (or GNEXes) you get. These things have no real ventilation, and there's no indication that they're going to start designing them with good ventilation that I know of.
Good luck, power user. Users like you force them to think about their poor designs and improve them. But it definitely won't handle a lot of 4g tethering without overheating. I'd expect that, without ever even having a Rezound (even though I have one).
They say 130 is the kiss of death for the Rezound but even if you're peaking in that neighborhood I'd swap out the phone for a new one. 120-130 degrees...That's like keeping lava in your phone and hoping it doesn't melt.
I hit 130 with my Inc1, and it was fine. Just navigating, not charging, for 30 min did it lol.
Mine heats up excessively and burns thru battery even sitting idle with airplane mode enabled and GPS turned off (damn Verizon and their location agent they snuck in with the update). The issue here is:
A) I'm not using it nor touching it period for a few hours at a time and its still already below 30% battery without my having used it.
B) yes I have an extra battery but when I try to switch out batteries it goes into a bootloop and won't recognize the Sim card for the next half hour.
These are my problems. I have yet to exchange it cause let's be honest...who here enjoys setting up a whole other phone? Should I seek a replacement?

Back it up to your ext card and exchange. Don't forget to hard reset. They are sending refurbished units with prev owner data out there. Should only get hot when playing intense games or streaming lots data.
I had this heating and severe battery loss problem. There were times my phone would run fine and other times when it would lose 40% battery in 30 minutes. It seemed to be worse when I was moving around the city (changing towers???). I even had one experience where I turned the phone off and it continued to generate lots of heat until the battery died while supposedly powered off.
I tried every stock and rooted GB rom (no ICS) on XDA and a few not on XDA. I finally "fixed" it by RUU'ing my phone to the latest OTA, rerooting and reinstalling all my apps (no TiB). My phone now runs about 16 hours on a charge and only gets slightly warm (never hot) when you would expect it to.
I did a fair amount of reading and never did find an answer but my suspicion is that something between the rom and radio got out of sync resulting in the rom not controlling the radio properly. No science. Just a theory...
Hope this helps someone, somewhere. I know I've gotten lots of help from others on here.
Thanks!
Had many heat concerns/ issues with my rezounds in the past, now have a phone that games at about 115. My opinion after much research is that a 115 peak is about normal for this generation of phones (Gnex, S2, etc). Anything better than this is not the norm and if you get one that stays cooler, it's just luck. I had one that used to get around 150 so at 115, I never even notice anymore. My rule of thumb is to just keep exchanging the hot ones until you get one in the comfort zone. Unfortunately, it's just the reality we're dealing with until they start equipping better cooling solutions.
OK, first I think we need to understand if people are talking F or C when they throw out numbers like 124. If that is C, you have a seriously defective unit. If that is F, that is like moderately hot tapwater, and neither too hot to touch nor hot enough to damage solder joints. If it were, the computer I'm typing this on would be dissolving in my lap.
Welp
I have many a thread out there on this topic. I did 3 swaps for new units during my extended "no regrets" window, and this past week got 2 different refurbs for comparison. Here is my 2 cents (but based on a LOT of research and testing):
1) These phones run hot. If you look hard enough at XDA you will see people posting along the lines of "I don't know what you are talking about, I use my Rezound to chill a beer" and other such. You might be best to ignore those people.
2) There are some VERY bad Rezounds out there, but those are easily found. Those that jump to 130 straight off because they started to download some updates gotta go back. That was refurb 1.
3) My experience is that idling at 75-80 will produce 106 on a short HD game, 110-120 on a longer HD game. You might get 113 on Navigation. It will heat up to 100 on surfing (longer if you have more), but otherwise topping out at 120. If you fit within this, stop your search, and try to enjoy your phone.
Again, just my 2 cents.
I haven't done extensive testing, but I have noticed that when my phone has overheated it has always been when I left something running on it when I locked the screen. I've started hitting the home button every time I put down the phone for more than a few minutes and I haven't had many problems. I definitely get toasty when I play games while charging though.
As someone else already mentioned, the phone needs to get quite a bit hotter than most people are experiencing before it starts having problems. With how small the phones I would expect you would receive an instant 1st degree burn from touching it before the phone actually had problems. 150 C is somewhere around 302 F. For reference, I usually solder 400 F.
My first rezound got around 135 degrees I took it back the next day.

This laptop is running at 120F just looking at this website, and it has active cooling.
Imagine a 1.5GHz dual core PC and then unplug all the fans, including the one on the CPU, and then close up all the openings in the case. Do you think it might get a little warm?
Not only do you have the CPU generating heat, but the more current you draw from a battery, the hotter it gets. And we all know how this phone can draw the battery.

There is something wrong with your phone. I swap batteries instead of charging, swapping out 1 extended battery for another (got them onsale at verizon when they were 20 bucks), and the phone boots up in about a minute.
If it is bootlooping, then I would try a hard reset first, then contact verizon and tell them about it.
As far as the OP goes, if you are in a poor signal area, I have read in multiple places that phones use more battery and generate more heat if you are in a poor signal area.
Swapping this for a Nexus will probably get you no 4g at all.
I wouldn't worry about the phone unless it was consistently getting so hot that the LED starts flashing amber.
My Rezound has peaked at 140 according to System Tuner Pro. I was charging and web browsing as soon as I woke up, like what I'm doing now lol. Was on 3G. Also, I wasn't overclocked at all. Governor wasn't even on performance lol.

lol dude, there is no point in ignoring us people who say our rezounds run cold, because of the fact that there's rezounds out there that don't exhibit behavior like yours.
i've seen all of your threads, and commented in all of them, and you got 3 shotty phones, plain and simple man. my phone never reaches over 100, even with over an hour straight of screen on browsing, facebooking, youtubing, gaming etc. so there, i have a normal rezound. it's from launch day, and it's never given me any problems like that whatsoever.
so no, don't ignore us who have cool running phones, because there IS such a thing..some people just have really bad luck dealing with it.
also keep in mind that the past two phones you got WERE refurbs. you do realize the refurb pool is gonna be full of hot running rezounds, since a lot of people returned the phone due to heat problems, right?
I believe some of the Rezounds get hot due to software issues. My phone will stay room temp and run for 16+ hours on a standard battery while running any GB rom . Once I flash any ICS rom my battery averages 90 to 120 degrees. As it is charging next to me right now, it is sitting at 104 degrees while doing nothing. I could switch back to a GB rom right now and it would be sitting around 80 degrees. So I believe some if not most are software/firmware issues. I am not saying their aren't ones with hardware issues but it can't be all of them.
I have ran the OTA update and am running Senseless ICS.

Toggle Airplane mode = MUCH better battery life?

I've had a combination of two weird / PITA problems since upgrading past LE6 leak:
1. Slow to lock GPS
2. REALLY bad battery life (losing 10% an hour while idle in some cases).
In the last few days I was at a conference with known poor signal indoors, so I started toggling Airplane mode on during some of the sessions. I noticed a DRAMATIC change in battery life. I thought the improvement was too good for just having disabled for about 2 hours each day, so the last two days I've toggled Airplane mode on and immediately back off after heavy use... I've done this today and after frequent use repeated the toggle routine. At the time of this posting I'm sitting at 70% at a time of day I'd usually be around half that.
Anyone willing to try this and let me know if I've just been lucky the last few days?
More info:
I've run CPU Spy and I know my phone isn't going to deep sleep as frequently as it should. I installed better battery stats and nothing was causing partial or kernel wakes so I was about to give up.
I believe this may stem from the GPS having crappy lock time, since I frequently use Facebook on the phone and it activates GPS (and doesn't F'n lock) I figured airplane mode after use couldn't hurt.
Qualifiers for a valid test include the two problems I mentioned above. If you're lucky enough to not have these issues, please recommend your settings... WiFi is off with screen off, i'm using screen filter at 38%... I've tried task killers, I've tried many different ROMs... this is the first time I've seen any noticeable improvement.
I heard that powering down your phone completely works even better...not sure though, might need to test it.
Jk. But yeah, it's well known that the radios are one of the biggest drains of battery besides the screen. Turning them off will obviously increase battery life, but it also turns your phone into a big iPod touch, as you can't receive calls, texts, etc. Add for the GPS issue, several roms have zero GPS issues, try them out, see which gives you best GPS. And turn it off when you're not using it.

I heard that powering down your phone completely works even better...not sure though, might need to test it.
Jk. But yeah, it's well known that the radios are one of the biggest drains of battery besides the screen. Turning them off will obviously increase battery life, but it also turns your phone into a big iPod touch, as you can't receive calls, texts, etc. Add for the GPS issue, several roms have zero GPS issues, try them out, see which gives you best GPS. And turn it off when you're not using it.

The battery life advantage exists even when the radio was only toggled off for about 1s. I'm no longer leaving it off for hours.
Yeah, probably because it kills the GPS searching for satellites. So either flash a new modem or ROM. I leave my GPS on 100 percent of the time, as when it works properly there is no battery drain when an app isn't using it. The GPS is known to be hit or miss with lf6, so take that and fix it with a modem flash.
Edit: in other words, your toggle method won't improve battery anymore than a properly working modem, and it's a lot more of a hassle to you to keep toggling instead of trying different modems

Do you have a recommendation on a modem then? I'm currently using King-Kang (love AOKP and Paranoid Android... Dagr8 did one hell of an integration). I've left the kernel and modem alone since then.
I'm using LE2, you really just have to try them and see what works best for you.

What is Causing Some Folks to Have Truly Horrible Battery Life?

Because Im seriously curious... This phone has a rap of being "atrocious" in terms of battery life... Now I'm not making this post to be mean or anything, In fact I really do want to know what IS causing it or some theories.. and share one theory I have
But my personal experience really says otherwise, Tonight I set a new "record" on my One X+, 16 hours 28 minutes with 2 hours 43 minutes screen on time... And I didnt do anything "extreme" to achieve it, My Google Now is on, my location services are on, autosync is enabled.. About the only thing I have done is install JuiceDefender (My previous record without Juice Defender was about 15-something hours) I watched youtube videos, Read some websites, listened to music, and even played some games... I'm completely stock, no roms or anything
Now, I will note, I had a problem the other day where my battery killed itself, FAST.. After a bit of digging around and tweaking, I discovered the cause was that my One X+ wasnt entering Deep Sleep, and thus the processor was staying at 475mhz or so even when the screen was locked (Causing the battery to be drained like i was using it) What caused this? My Wi-Fi, of all things, While I had a really good signal, I had it prioritizing the 5.8ghz radio, and in my room, the 5.8ghz signal is fairly weak as im a ways from my router... so the phone was switching between it and the 2.4ghz signal, causing the phone to be unable to sleep, Removing the 5.8ghz AP from my phone fixed the issue completely and my phone returned to "normal" behavior...
Yeah i know it sounds really farfetched and weird, and took me a bit of googling to get the idea that this might be what was causing my issue (I tested my hypothesis by turning Wi-Fi off completely and using Cell data, Sure enough my phone slept like a baby and barely used any battery.. i flipped Wi-Fi on and suddenly the phone was drinking its battery down rapidly.. I disabled the 5.8ghz AP and suddenly the phone worked 100% properly again)
I suspect that this is the cause behind some folks who are saying their phone is draining down 7% in 20 minutes with it locked, Its simply not entering deep sleep, the processor is doing something in the background... Could some of them be having the problem i just described? Its possible, Especially if you have multiple Wi-Fi points in your house.. Could the wi-fi in the One X+ be bugged? I dunno, Thats possible to, Thats why I'm posting this...
Now of course some people need a phone that is going to go for 2-3 days without a charge, and no, this isnt the phone for you (There arent many smartphones out there that can manage that if you actually USE it any) But really.. 16 hours with 3 hours of screen on time is pretty darn good.. Thats getting quite close to my Galaxy Nexus with a 3500mah Extended Battery (Around 18h standby, 3.5-4 hours screen on) despite all of the "handicaps" the One X+ has over the simple GNex (Like LTE and a Quad Core processor) and is vastly better than my stock Galaxy Nexus battery which died constantly...
And yes, heres a screenshot as proof if you dont believe me...
I just want to add that I find that googlenow also drains the battery and as such I always disable it. It was a problem on my S2 and thus I have disabled it on my HOX+
Honestly, mine wasn't lasting longer than 8 hours until I rooted it and simply "froze" all of the AT&T apps I wasn't using. That alone gave me an extra 2-3 hours a day of battery life! (I've read here that the AT&T apps, even if you aren't using them, keep running in the background) The other thing that seems to help is an app called Smart WiFi toggler that's done wonders for both myself and everyone else I know who uses it in terms of minimizing WiFi battery usage.

I'm sure other folks have other tips, but this has been the winning combo for me.
I should add that i also froze every ATT app i could and never opened ANY of them.. So maybe thats part of it as well..
JuiceDefender i believe is doing something similar for me with the Wi-Fi by turning it off when its not needed...
My battery life was terrible when I first got this phone. I let it charge out completely once this month and I've been using LBE Security Master. Those two things have greatly extended my battery so much I have been able to go more than a day with it before charging. Another factor might be that my phone isn't carrier branded or anything.
The "My Wi-Fi isnt letting my phone enter deep sleep" thing is actually starting to get annoying, I thought i fixed it but it keeps coming back...and yes, it is legitimately killing my battery at twice the normal rate because the phone will -not- enter deep sleep
My phone goes into deep sleep just fine if i turn Wi-Fi off...and my battery drain returns to normal....So it cant be some app downloading stuff or constantly pinging the internet or else it would do the same thing when im on LTE...
Also i've reset the "Keep Wi-Fi on during sleep" option to never 20 times now, it keeps going back to "always" on me...
Ideas?
My battery life is ok. See here:
http://forum.xda-developers.com/showthread.php?t=2067143
Mine is too, Provided i turn Wi-Fi off or i get the bug to go away for a bit (basically toggling wi-fi on and off a few times and twiddling with the settings makes it work right, but the problem comes back minutes or hours later)
Otherwise, Wi-Fi wont let my phone enter deep sleep, and my battery drains like im using it..
The thing thats annoying me more is that the "Keep Wi-Fi on during sleep" setting will not stay where i set it and keeps going back to the default setting....
I guess i can just toggle wi-fi on and off manually...

[Q] Bad Battery Life

Hi, New to XDA, also new to the S4, currently my battery life is quite bad, I am attaching a couple of screenshots so that you can get a better idea of whats happening with my phone.
Here is a list of items that are on:
GPS
WIFI
Mobile Data
Sync ( Google account only )
Brightness ( Auto )
The problem I have is that I have heard a lot of people say they get 3-4 hours of screen time, as you can see from the image below, I have only had 38 minutes of screen time, one thing I will add is that my screen gets warm when I am using it ( you can feel its warm/hot when you touch it ), is this ok?
Any help will be greatly appreciated.
Thanks!
there have been a lot of reports saying if you are on wifi and idling battery drain is really bad
how bright is your screen set at?
not very good results, I would buy another battery first, no hurt in having a spare, and see if it is doing the same, cause, looks like you have nothing really eating up the battery. Then if that does not work, I would go for a replacement.
Good Luck!
First, are you rooted and/or running a custom ROM? If so, was your battery any better on stock? I'd hate to suggest it, but Verizon would anyway, have you tried a factory reset, and run without apps to see if it's any better? You're right, though, that it doesn't look like much is killing the battery. I'd go for the replacement through Verizon if it doesn't improve.

I had the bad Wifi Idle battery drain..After 2 weeks of trial and error (and reading through tons of Shark Logs) I tracked my issue down to Multicast being enabled on one of my access points.
I recommend the OP log into all of their Access Points/Routers and disable any reference to Multicast...Of course you wont be able to on a school or work network (unless you have the proper authority and about 300 change management endorsements..but I digress).
I have several AP's in my house..little did I know that an old WRT54G (with tomato firmware) had Multicast enabled..it was causing a lot of noise on my LAN and only my S4 and S3 were affected...No other Wifi devices seemed to care..and I wasn't even connected to that Access Point..It is just an old AP I have on for some Legacy devices on my LAN.
Once I disabled Multicast, my Idle battery returned to normal..Then I had the "runaway Google Services" issue that some people have, but then I just disabled all Location services on my phone and that returned to normal.
TLNR - Disable Multicast on you home router and any access points you have on in your LAN.
