I posted in the wrong thread earlier but here's the situation. No matter what rom I run, wifi won't sleep. Optimizer is off and wifi on during sleep is set to "only when plugged in". I've rebooted the phone and will post back to see if that fixed the problem. Just wanted to make sure that I should see the wifi sleep when the phone sleeps, correct?
Now that I'm thinking about it, maybe I should be asking this question. What drains more power, wifi always on or a phone trying to stay connected to a very weak 3g signal?
Reboot didn't solve the problem. Maybe its a reporting issue. I didn't hear any notifications and when I woke the phone it messaged that it connected to my network. Dunno!!

I know my WiFi takes a few minutes to actually turn off after the system goes to sleep. To me it seems as if there's some timeout where it waits x amount of minutes after the last data access before it turns off? But that being said... it does look like your system is waking up an awful lot even when the screen is off. I might venture a guess that you've got some app that is keeping the system awake and in turn holding open the WiFi connection.
Have you tried Better Battery Stats to see what might be going on?

I'll give that a go.
And a weak 3G signal will drain battery A LOT faster than wifi because the phone keeps searching for new towers where it can get a better signal from.
I've only had the phone 5 days, maybe I should just swap it out.

Listen to this man, he knows what he's talking about.
I hang out with friends every Thursday night down in Long Beach. The friend's house we go to has horrible 3G reception. I never connected to his Wifi and always lost 40-50% of my battery in the two hours that I was at his place (without even taking my phone out of my pocket). My phone would be hot and I'd be losing power faster than Apollo 13 (too soon?). Once I started connecting to his wifi, I'd see a drain of 5-10% in those same 2-3 hours. No more burning pant pockets, either.
That being said, I don't think it's the wifi that's causing your battery drain. Looking at your battery screen, something is keeping your phone awake most of the time. Also, as suggested previously, Better Battery Stats is a great program that can help you see what's causing Kernel Wakelocks and Partial Wakelocks. Once you find out what's causing this (typically some sort of data sync or gps services), you can make the choice of that app or battery life. It's made a whole lot of difference on my battery life. Note: Better Battery Stats won't fix the problem for you; it's just a tool to help you find the problem so you can fix it yourself. Don't expect it to make julienne fries or cure your sepsis. That's what the Shamwow is for, of course! Ok, it's late and I'm getting goofy. I'll check in to see if anything helped.

Oh, I'm not worried about the drain...I was using the phone heavy in the above screen shot. I'm worried the phone is defective if the wifi won't sleep at all when the correct settings are chosen. It should sleep, and if it doesn't, then in my mind the phone is broken. It's a six or 7 day old phone...it should be flawless. Right? But, per all your info, it appears it's only a cosmetic "broken" phone. My wifi will be on when at home 100% of the time because Sprint's signal sucks ass here. Either way, thanks for all the info everyone.

hey guys, noob question here, but wanted to know how to properly read these battery graphs.. totally new to android.
what is the difference between the reading up top and the reading above phone signal? also, im guessing with phone signal, yellow = bad phone signal?

I have been using android a while now and I can't answer that... My phone signal is green and yellow stripped and I have been at home with 4-5 bars the whole time.
That graph tells me you have have wifi on all the time. You have a wakelock problem. But other than that it's good.
Sent from my SPH-D710 using xda premium
haha! thats actually not mine, i stole that screenshot from another forum post
I just dont know what the difference is between the two readings, always bugged me since the two readings always seem to be like a few minutes apart or something, even on my phone
While we're on the topic of battery and wifi wakelock, can you guys help me understand what I'm seeing this morning?
So here is my battery usage since I took the phone off the charger this morning at 8:00am. The awake bar makes sense, as I stream an audiobook via bluetooth in my car on the way to drop off my daughter at school, then on to work (daughter drop off explains the blank spot between the two solid bars of being awake).
But what gets me is Wifi. I was connected to Wifi at home, and have been connected to wifi since I arrived at work, but definitely not while I was driving to work. So is this normal behavior? In other words, if wifi is enabled, I'll get a solid bar the entire time whether I'm connected or not? I guess this is a situation where the phone is constantly seeking out a wifi connection?

This difference in the time numbers seems to be a distinction between "on battery" and since originally unplugged for the day. On the bar graphs below, you can see charging was registered for a small part of the day, which could explain the 30 min difference. Of course, the line graph doesn't seem to show any charging happening, so take that with a grain of salt.

Yes, this should be right. The "on battery" time is the time the phone spent unplugged. The time below the graph is the time period covered by the graph. Right now my phone shows longer "on battery" than the graph covers.
There appears in that picture to be a period of ~30 minutes when the user plugged their phone in and used it as a GPS nav, probably in the car, which resulted in some battery drain but not as much as GPS might have otherwise used.

Good call on the gps/plug in theory...seems right to me, too.
Agreed also that the time below the graph is the amount of time represented on the graph, but what triggers the initial starting of the graph?? I'd think it would be in initial unplug, but your experience (and mine, too) with less time under graph than listed above "on battery" suggests otherwise. Any ideas anyone?

Once in "Battery Usage" click on the little mini graph at the top of the screen, and it will take you to a large graph. This larger graph will be the same one that is being viewed here.
I'm curious, on the original EVO, you could see exactly how much time it has been since it was last charged, it would tell you minutes and hours instead of guesstimating based on a graph. Is there any way to do that on the newer android devices?
Yes settings/about phone/status/up time
Settings /about phone/battery usage/xx hours, xx min, xx sec/touch the top for details.
My battery died in a few hrs today and the culprit seems to be 66% cell standby. I've never experienced this kind of drain before. I'm running the latest Franco Kernel and I'm wondering if anyone else is seeing this?
I just posted something exactly like this earlier in the day. Do you have google chrome and recently updated? I think when I just uninstalled it, it fixed my problem...
Sent from my GT-P7510 using xda premium
would be amazing if you actually posted a screenshot of your usage, with awake time, screen on time, and network state....
Leave your screen on all of the time. It will make the cell standby percentage go down .
On a serious note. what's the time without signal? Just press on cell standby and it will tell you the percentage I think. It sounds like you didn't have coverage and your phone was constantly trying to find it...which would kill your battery fairly fast and probably make your phone warm in my experience.

What did your network level look like over that drain? It looks like you have bad signal, but it shouldn't effect it that much if you're on WiFi the whole time... as noted before, a radio constantly hunting for better 3G/4G signal can really drain the battery.
How much screen on time was that? Probably pretty low?
56% of the time you were without a signal? Where do you live? Alaska? On a serious note though...I'd recommend switching to 2g/3g or wifi when you're having trouble finding a signal.

WOW yeah didn't even see that. There's the drain right there. Your phone is boosting power to the radio to try and get a signal and just obliterating the battery.

At home, my signal is generally 2-3 bars 4G, maybe we're having tower issues in my area. This battery consumption is definitely not the norm for me. Kind of took me by surprise which is why I posted...

So it is true that when your phone did not have network connection, it will constantly find coverage and thus account for the awake time in the battery state? Therefore eating up the battery life, even though the screen is off?

Yes. This is true. The phone pushes more power to the radio also, which drains the battery.

This is irritating me immensely...my Galaxy Nexus has yet to last me a full day on a charge. I bought a Hyperion 3800mah battery and I believe it really did extend my battery life. On Sunday, I was home all day and my phone was connected to wifi. I used it quite a bit and the thing had 80% when I went to bed.
Today and yesterday, going to school, my phone is just about dead when I get home, at 2:30. I did use my phone, but not heavy at all. Spent the most of the day in my pocket. I had nothing on both days. No bluetooth, GPS, I had sync off when I went to school today, then I turned it on around 1 o clock or so. I used full screen brightness when I was outside for a few minutes, otherwise it was on low. The thing is warm to the touch like its been running frantically. I'm lead to believe that its something to do with the LTE radio. But what??
Took some screen shots of my battery page, had 4% left.

Please please please help me. I've read people getting 2 days on a charge with a 3800mah battery...I'm drooling for that ability.
Thanks!
It looks like your spending lots of time in area's with bad reception. I'm using the sedio 3800mah and I have no problem going several days on one charge. Only time it drops faster is when I have crappy reception and the radio's are pulling more juice. On heavy days I have wireless tether running all day, and a couple hours of games and still have 40+ percent at the end of the day.
there is also some crap app installed that keep ur phone awake..
ur phone should be awake only when the screen is on (or so)..
your high % of cell standby should give it away.
look at your signal the red is all the times with no signal meaning that whole time the phone is searching for signal. plus 49 %of screen on time that looks to be half of 7:49 so almost 4 hours of scren time is good just need to fix your signal problem plus draw something kills your battery as well

Turn off LTE, bad signal will drain you fast but bad signal on LTE will drain you twice as fast.
Looks like you have a rogue app. See how much your phone is awake when the screen is off? That combined with bad signal=dead phone.
I see what you guys mean about awake mode. Yea my phone feels like a warm coal all day. I uninstalled "Words Free" because I've heard bad thing about battery, I stopped using the beautiful widgets weather app, stopped sync with soundcloud, and I got an airplane mode widget for the bad reception area. We'll see how long I can stretch my battery tomorrow.
I read up on how Light Flow light might drain the battery. The LED light has remained stuck on a lot, so I uninstalled it. I'll post a battery stat tomorrow night. Fingers crossed.
I can vouch for bad reception draining the battery.. that should clear up your problem.
Sent from my Galaxy Nexus using xda premium
I had the same problem but get this app called "2X Battery", my batter lasts the whole day now! Get the PRO version, its actually worth it and it works wonders!
I have the extended battery also
yep bad reception... once time i left my phone one in my bag while on an airplane... not in airplane mode or anything... battery went dead in about 2 hours due to no signal
Pretty sure the bigger problem is the phone waking up while the screen is off. You should run your phone for another day and look at the list of apps that are draining your battery.
A few good things to look for? Google + or other programs constantly checking for messages your location, or updates, e-mail being pushed to your phone automatically, Wifi on while in sleep, and widgets.
My battery is **** also on GSM version my galaxy s2 would have 2-3% drain per hour most time less Nexus seems to drain 2-3% in 15mins its terrible wish i never changed.

I am stock rooted
This battery drain is so pathetic, please help me out on this one guys.
I charged to 100%, then played games for like 50 minutes, Plants Vs zombies for around 32 minutes and Kingdom rush for the remaining.
Charge became 84% , not sure if this one is to be expected.
But the main issue was the drain during screen off, i went to sleep when the charge was 84% and the device was screen off for almost 8 hours,
I woke up and checked, now its 66% ???? . really around 18% drain during a 8 hour screen off window
This is so lame, i checked the battery usage, nothing seems out of the ordinary, yes WIFI was On the whole time, is that the reason..
Does the notifications cause battery drain?, i had received some mails and t-mobile my account crap had sent some notification and LED was glowing all along.
i moved from note 1 only because of the stupid drain during screen off, its annoying , i know we can switch off WIFI, data, restart the device and use some app to reduce the drain, but i thought the battery will be good out of the box with Note 3, this feels the same like my note, no difference, something is messed up.
Any help is appreciated sorry for my bad English.
that idle drain seems very excessive. I lose like maybe 1% overnight. have you managed your accounts and only sync the necessary things? that could be a big drain.
Yes thats very excessive , thats why i am losing it, i did check for syncing, apparently nothing was running overnight.
Could be because i have only one point in the network signal? , not sure, i did check on the Cell standby it said "Time withou signal 0%"
i never had 1% drain overnight , would be nice if i can find out a way to make it work for me as well.
Call me strange, but if i am going to be sleeping, I plug it in. When I wake up even with just a nap the phone is fully charged.
i do too.. but i want to check the battery drain during sleep, often when traveling, i wont even use the phone but it would have drained , that's why i am checking how bad the drain is and the ways to fix it.
not sure you need these setting enable or not, but try uncheck all in Location Services under Setting.
Maybe you should start with basics and see what have you changed, since this drain begin?
For example I was trouble shooting WiFi calling and followed one of suggestions to shut down WiFi power save in service menu. It didn't work (updating router FW did the trick) and I forgot about it, but then I realized my phone was discharging 20% overnight (yeah, I charge when come home from work, by the time I go sleep phone is fully charged) and this was way too much. To make long story short, once I put WiFi save mode back on, I get 3% discharge overnight as it should be. The problem with such high discharge rate was that the phone barely lasted a day of light use and if I forgot to charge it night before it would be dead before morning. It also kills battery to have it fully charged daily, battery will lasts much longer if the charge is light (80% to 100% for example.)
Yup, i think it was this Wifi power save option in the service menu, i had switched this off and forgotten about it. thanks for reminding me .
i will check tonight as well.
Bad thing about this setting is, its very hard to pinpoint if you had forgotten about changing this setting, it wont show up in any of the battery usage app.
Go into wifi, hit menu and go into advanced settings. Uncheck wifi always scanning.

Those 2 games kill battery like a mutha, even if you kill the screen. I always use androids built in task killer by holding home button for a few seconds and killing battery hogging apps like those. If i do decide to end up installing those again and playing them i can expect shorter battery life for sure. Ever since i stopped gaming on my phone less and just game on my 360,ps3 and now wii u(kids got 1 for xmas,mario 3d world is addicting lol) ive seen huge boost in battery life and light to normal battery consumption on common sense settings for our phones.

I have an unrooted M919 which is running 4.4.2 (FNB4). Problem I have is when LTE is on, and I have about 2 bars signal in my room, the battery drains quicker than when the phone is only on H+ /WCDMA.
My question, will the 4.4.4 firmware improve my battery comsumption?
Thanks
In general LTE is known to consume a lot of battery I recommend u stick to H+/WCDMA it what I do .
I doubt the new firmware will have any battery improvement
LTE alone is a battery drainer
LTE is not that bad a drainer, its low reception that will consume a lot of power. The update may not help much, but doesn't hurt to try
I have already packed my M919. I will return it... it makes no sense keeping it it I still have to disable LTE... I will just keep my stellar i9505
The reason I bought the M919 is to have LTE, but I never expected it to suck my battery that fast. I went out with the family to do some shopping this afternoon, from 4pm with 75% battery ( I have rebooted the phone, and greenified everything I can), then after dinner at 8pm, I had 35% left on the battery.
Unless you were actively using it the whole time there is no way it should drain that fast. Did you check battery stats? I wouldn't give up that fast but it's up to you

That kind of drain is not caused by LTE.
+1. Even in marginal signal areas where it is spending lots of energy hunting for signal, it should not drain that fast.
Definitely investigate what is causing power drain. At that rate, it's not LTE or "hunting for LTE" that is causing it.
LOL.. I hate you guys... I will have to unpack the phone and start again then....
But seriously, I have used all Samsung phones... look at my signature LOL... I have never had this kind of battery drain... but I will give it another try, but I am not optimistic because I have reflashed the firmware twice, and have reset the device about 4x already with the same issue...

I also always disbale things like google+, and other samsung bloatwarez... so nothing really sinisterly running in the background

What about the stock battery stats? And also do you have Google now disabled?
These are what I habitually disable:
(I am surprized, "SNS" which is related to facebook and twitter is not on the NH7)
I don't have facebook, twitter and other social media apps installed....
The 4G signal you see in my screenshots is because I only used WCDMA connection at that time.

Just an update, I went out this morning for about 2 hrs. Only time I used the phone was when I received a call which lasted about a minute, used the calculator once for less than 30 seconds, and the only times the screen was on was whenever I checked is if I have LTE signal...
I notice, the "Wifi" is "On" but I am sure I have turned it off. "Wifi calling" is also disabled in case you ask...
Go into WiFi, settings, advanced, and disable always scanning. I forgot about this one, it is a battery drainer for sure. You should get much better battery now
