This is for the WiFi only A500.
Just noticed that if you install the power control widget (the free one) from the market, and configure one of the buttons as a 2G/3G switch, on pressing it you get to a menu that's not available through Settings (is missing from the WiFi and connections menu). There you have the option to unselect the Data enabled checkbox. I'm not sure yet, but I seem to be getting better battery life (although Cell standby will still show up in Battery use; still, that value is a percent of the total drainage, which seems to be smaller).
Please try it out and let the others know of your results.
Noted Before - Did Not Seem To Resolve Much
Actually many widgets have the property of opening up "hidden" settings, e.g.,

Wow! I just went into my Beautiful Weather settings and under the "Advanced Panel" you can specify an action for clicking on the time (or weather). When this is done, it provides a large list of action - this list, to the best of my knowledge, doesn't show up anywhere.
Anyway, Mobile Data was checked (yes or on) so I cleared the list (resulting in mobile data being UNCHECKED) and rebooted. Mobile data remained unchecked so I'll watch for a while and report results later.

Could be placebo, I agree. Well, no harm done in any way
sure fire fix
Although it has been said that by renaming the phone.apk and telephony.apk you may risk bricking the device during a factory reset, I have renamed both and have seen an incredible increase in battery life.
Currently at six and a half hours of moderate use for music and web with some standby time and have 88% battery left. No cell standby being shown in battery stats either.
Reboots are fine, just don't factory reset without renaming the apk files back.
Installed Free Power Widget from the Market, says its installed but doesnt show in my widget list, strange.
Cell standby is simply terminology for when the tablet is asleep meaning screen off. So I wouldn't start changing it. In all likelihood you have an application that tries to access those two apps and when it doesn't find them it can't run its background process. I bet finding the culprit app would equally fix battery life.

I had the same, switch off and reboot made it appear in the list.
In much the same way photos I copied from a portable hdd onto the micro SD didn't show until I had powered off and on again.
Thanks, that did the trick.
@Canadoc: "Cell standby is simply terminology for when the tablet is asleep meaning screen off. So I wouldn't start changing it."
I do not believe this is correct. If this were true, removing Phone.apk and Telephony.apk would not affect battery usage, because the tablet would still use just as much power when the screen is off and it would still list "Cell standby" on the battery usage screen. In actuality, removing these two apps causes Cell Standby to disappear from the battery usage list and decreases actual battery usage. Plus, my "Cell Standby" % on the battery usage screen is highest when I have my tablet awake all day, and lowest on days when I let it go to sleep much of the time. So it must be doing something else in Cell Standby that uses power, probably trying to contact cell towers (in vain) even though it is a wi-fi only device.
A few minutes of Googling reveals that many Android wi-fi only models have the same problem (they try to access cell service even though they have no cell capability) and removing Phone.apk and TelephonyProvider.apk seems to fix the problem for everyone who's tried it. I have rooted my own A500 and removed them and it has given it an extra hour of battery time per full charge. YMMV, and it may someday brick when there's an update or something, but for now it works great. Cell standby was definitely doing something that it is now no longer doing.
I'm not 100% sure if android respects them(more experience on Linux than Android), but couldn't we just remove the exec flag off of the apk and not worry about bricking?
Or possibly set it's owner to system and deny rights to everyone but owner? Would that still allow updates?
I thought anything PRIOR to Honeycomb was made for phone ? ( froyo, gingerbread ...etc )
That info was actually made in press by Google !
So in essence, HC is for tablet ONLY ! why are we still seeing cell standby and phone apk ?
even if you argue because some tablets are 3G models ... 3G is about DATA ... not making a phone call !!! ( imagine bringing a 10" device up to the side of your ears )
there are some 7" tablets that are GSM capable... so, they CAN make GSM calls, and they DON'T use Honeycomb either.
anyone care to enlighten me why here we are with Honeycomb and still have the cellstandby and phone APK ??

Because Google are a bloody idiots?
Because hc was built on gingerbread. It wasn't built from nothing.

I'm sure there are others who have experienced this problem. Even though I show no wake locks my phone drains at an unacceptable rate while on my Wifi at home. My phone can have a 60% battery when I go to bed, and be almost dead by the time I get up. The only clue that shows up in Android System Info or Spare Parts is network usage by '0' which is something with root access.
This is happening regardless of Rom. I've tried stock, Syndicate Frozen, Urban Fury, Bonsai, Stock Plus, and maybe another I'm forgetting. They all drain the crap out of my battery with wifi on at home so obviously this isn't a rom issue.
This leaves me to believe that either something on my network is forcing data to my phone keeping it from deep sleep, or the router itself is the cause. Turning on my phone to 3G, my battery life is spectacular overnight. It deep sleeps like it's had a case of beer with a bottle of nyquil as a chaser before bed. 1% an hour.
So, I've ordered a different router to see if that's the issue. I've googled my current router which is a D-Link DIR-655 and seems like others have had similar battery drains using that router but no one can emphatically say it for sure is the router. Guess we'll see when the new router arrives if it is indeed the DIR-655. Otherwise the next step is disconnecting everything else that is connected to my network (3 computers, 2 printers, XBox, Wii and a Blu-Ray player. I just wanted to point out to anyone else having issues with wifi and weird battery drain, that it may not be the phone that is the problem.
I too have massive battery drain when using Wifi. It doesn't matter what Wifi network I'm attached to (work/home/friends/etc), I burn about 10% + per hour on idle; whereas on 3G is burning only ~2%/hour on idle. On stock, Wifi was my battery saving grace.
I've just given up on using Wifi for daily use. I use 3G for everything now.
I hope the newest version of SFR (whatever the new one will be called) will remedy this problem I have. I haven't posted about it in the rom thread since I had a feeling it was just my phone or another bad flash in CWM.
I've been using that OS Monitor app to try and find the problem. On 3G all the network interfaces have static receive and send amounts as long as I'm not doing anything that requires data. Connected to my home wifi, there is a constant trickle of data.
When I let the phone sit overnight, there was over 4mb of data received, even if I turn off any kind of auto syncs on the phone.

Don't know if this will work for you but you can try. In the wifi settings click the menu button and select advanced then set the wifi to never sleep. I know it's counter intuitive but I went to sleep last night at 61% and woke to 57%. Wifi has been fine for me since changing that policy in the wifi advanced settings.

Mine has been set at never sleep since I got the Epic in September, and I double-check after each custom rom flash. Good looking out though.

Same here. Mines always been set to never sleep.
Edit: I just tested my phone on my work's wifi network. CPU Spy says it's going into deep sleep just fine. OS monitor shows a static data received/sent number once I was connected. Obviously something about my home network is the problem.

That is my general experience, too. These settings usually keep my WiFi usage low overnight.
But some nights, inexeplicably, I will wake up to find a large battery hit from WiFi. I don't think it is my WiFi router's problem, unless there is some outage duirng the night I am unaware of. Come to think of it, I had that problem last night but did not investigate early this morning before I left. When I get home, I will check with my laptop to make sure my router is running.
I have noticed this too and in particular over the past few days. I'm on the latest bonsai build which does have amazing battery life on 3G but now wifi does draithe battery much more than 3G. This never happened before. I have had my wifi set to never sleep. Any other suggestions?
Obviously haven't tested it overnight yet, but I shut down my one laptop and the constant data trickle immediately stopped. Right now it's looking like something my computer is running might be the culprit. Going to leave it sit overnight to see how it goes.
I found the cause of my drain! Narrowed it down to something from my laptop as when I shut my computer down at night, the drain would go away. The culprit was the HP Printer software for my wireless printer. Once I uninstalled it, the drain went away. Noticed in resource monitor that HPZinw12 was sending a constant stream of data from my computer. Why in the hell it would be also sending to my phone keeping it from sleeping seems pretty odd, but I recommend if anyone else who is having battery problems over wifi and happen to also have an HP printer, you might want to look into this as well.
I'd also add that my solution to getting rid of the problem and still being able to use my printer was just to uninstall the crappy HP software that came with the printer and add the printer through the control panel and let windows 7 install it. It doesn't throw on that HPZinw12 file that apparently polls the entire network constantly.

Since I have been experiencing similar symptoms intermittently and I also have a WiFi printer, I have tried to eliminate this as a potential cause. (I don't run an HP control app on my laptop, but already map the printer directly in Windows 7 like you suggest.)
In my case, I still get the excessive WiFi battery drain, and low battery level upon waking, sometimes overnight. But other nights the problem does not occur. So lately I have made sure that my laptop and printer are powered down before bedtime. And like you, a always have my WiFi sleep policy set to "never" and have a strong WiFi signal. But last night I still had the problem, and awoke to find the battery drained to 45 percent instad of its typical 90 percent.
Interestingly, I noticed not only high WiFi battery usage but also high "Cell standby" usage attributable to the well-known Time Without Signal problem -- and this despite my habitual use of the Airplane toggle workaround, which usually works.
Somehow, something caused both WiFi and cell radios to go crazy overnight.
BTW, I run a stock, unrooted Epic.
So far with SRF v1.1.1, my Wifi is back to normal.
On my work network, I've dropped 4% in 3.5hours with my work email syncing every 15mins. So that's pretty good usage given that sync interval.
I also do not have a printer at home, so the printer bit wouldn't have been a cause for me.
While the printer thing took care of the biggest problem for me, I still don't get as good of battery life overnight leaving my phone on WiFi rather than 3G. There is still something my computer is doing that wakes my phone up occasionally, but at least I'm not going to bed with a 70% battery then waking up to a dead phone. At least I have it narrowed down to one computer (total of 3 on my network), as when I shut that particular one down battery life for my phone is back to 1% an hour while sleeping. If I had to take a guess at this point, might be something with media sharing as I use that one as my primary location for music/videos to stream via Windows Media Center.

How do you know it is your computer? Have you tried just turning it all the way off?
Do you watch the services running on your phone? I routinely stop the DRM service, for example.
Except for the mysterious episodes when I experience this intermittent problem, my overnight battery usage is typically about 1 percent per hour.

I've tested over a few nights with a mostly full battery off the charger and reset the timer on CPU Spy. The nights I shut that computer completely off, I get very little battery drain and the phone is mostly in deep sleep according to CPU spy. When it's on, the phone shows a good chunk of CPU at 800mhz and more battery drain.
After having the S3 on tmobile and having the official 4.1 update and using Google now all the time. I never had any battery issues. Using it on the N4 the drain is crazy. I I have to freeze it to stop the drain.
Is there a way to use Google now with out the drain? I do love me some Google now.

Err been using it for a month now and have -zero- issues with battery drain. and when i mean im fully using the phone, i do mean fully... it's wide opened, full net access, nothing blocked (except adware type junk).
I have everything from google installed, all their apps that sync constantly, plus tons of work related programs like office, remote print bots etc.. to top it all off my google drive + google music are being used all the time too.
No battery drain at all here. I'm sure it uses battery, but nowhere near a level of drain that is gastly or noticable. I'de more point my finger at a rogue app that you installed instead.
you try it from a clean install? or maybe uninstall all "extra" to try and narrow it down...

I'm the same, I have everything syncing, GPS on etc
my battery lasts 8 hours even with nothing extra installed except stock apps
I'm with you OP. Battery is crap on this phone compared to S2, S3 and iPhone. Web browsing is killer 4hours compared to 8 on iphone.
Google Now and location drains battery. Best way to tell is overnight - with those features on the battery falls all through the night. With then all off - its level.
you guys with drain are forgetting to mention what other apps you have installed and are running. Are you stock ? like stock stock ?
and another side note: your 3G cell reception... spotty??? if your radio is constantly trying to connect you will experience mega harsh drain - regardless of phone or programs.
so..ermm.. need more info you guys
3G (HSPA+) is full where ever I go, rest of time I'm on WiFi.
As I stated, I've tried with no other apps installed. Just stock apps with all Google stuff enabled
I see what you guys mean about rogue apps. But that is not the case. As a previous user said you can tell by leaving Google now on over night and turning it off(I've tested that).
I'm having great battery life with it off or on its just the batter seems to drain more then it should with Google now enabled compared to other phones...
Oh well, just have to live with it.
Thanks everyone

Silly question... did you guys program all your options into the phone so it's not constantly searching?
@MMACE - 8hours.. hmm..seems off a bit I wake up at 6:30 phone is unplugged then...usually only throw it on the charger when i get home later that evening.
I use the phone with all the trimmings during the day. sometimes video, sometimes music, sometimes browsing, wifi on/off etc..
Look with cyanogen modded kernel on a nexus one, i was getting 4-5 days of heavy usage and easily 2 weeks standby. I understand what it means to have excellent battery life. But we are talking a bigger screen, more features, and faster cpu speeds here...
you can't expect miracles of a week's usage here.. needs to be reasonable..
Google Now gave me some significant battery drain for the first day, but after that it simmered down and now I get great battery life. I always have everything turned on except for WiFi.
hmm that's weird. i'm not getting any battery drain from google now as well. i don't constantly have it open or use it all the time, but it's running in the background. for me, i actually use battery defender. i've heard different things about it and that it doesn't work. but it seems to work for me. i'll use my phone not too heavily during the work day or even the weekend, and usually by the time i go to sleep at night, it's down to maybe 40%...somewhere about 20% if i talk to my fiance a lot.
As mentioned ad nauseum, you should check the location (aka GPS) settings. GPS radio "only" works when apps call it (maps). The wifi portion runs all the time. If you turn on GPS, but disable (or simple do not agree) to use the wifi radio for location, you should see a large improvement.
Hi guys, Noob alert hahahaha. Long time stalker first time poster.
I like many others have terrible battery performance with my Note 3 N9005. Mine began 2 months after purchase, no root etc. Tried everything and sometimes it would be fine, other times drain like hell. Now I am rooted using chainfire, I run clockwork mod, use nova launcher etc. My wifi never sleeps, so I have to turn it off manually and for the most part since rooting last month, installing greenify etc, I can get nearly 3 days sometimes out of a battery, which includes streaming spotify, browsing etc (I don't play games on my phone). Still my wifi never sleeps. But every so often lately the major battery drain has begun again. Last night I went to sleep on about half and woke up nearly dead. I am attaching a copy of Better Battery stats in the hope someone can explain what the cause is. I also noticed the cpu running at 300hz for most of the time.

I think it is *#0011# ; I also suspect you might need to set power-saving ON there in the WiFi menu, but that is just my guess.
In your log above the main problem seems to be Spotify and some other programs with wakelocks, maybe also stuff related to Bluetooth and WiFi vs Mobile Data.

Wifi powersave was already on. Spotify runs pretty well all day at work. When at home bt and wifi are always switched off before I go to bed. My other issue and one I assume most note 3 owners have, is using the internet sucks 1% per minute. No joke. I can listen to music for hours and lose 3%, but use the web and I lose 1% per 1-2min. I lost 3% just typing this. Only once and it straight after root, did my phone not lose any percentage whioe on net for 15min. Uninstalling google play used to help also, but that does not seem to make any difference anymore. I never use location services or auto updates, so bugger me how to fix this.

Reset BBS statistics and do a log for one of those periods of just a few minutes when you lose 1-3%.
Also check if power-save mode in the phone makes any difference.
Today I noticed this wakelock kept my device away 80% or more of the time it has been on battery (11h13m at the time of posting this). To give you an idea of how little I used it in the time screen on time is only 33 minutes. And the only time I used it for anything was when I had the screen on. I can't seem to track down any info on what would be causing this wakelock on my s4. I found in a google search about this on other devices like the nexus which pointed back to a thread here on xda that said it is due to " the 3G modem is connected to the phone as an external USB device controlled by the hsic host controller". Problem is I don't use USB for anything with my s4. No new apps or changes have been made to my s4 in ages so I can't even contribute it to anything that has changed recently. I use the same apps I have been using for ages. I've been home all day today as I had the day off. I use wifi at home. CPU spy lists my uptime as 29 hours I rebooted last night while out with friends because flixter wasn't working right. After the reboot flixter worked fine. And I put it on the charger when I got home. In case any of this has any bearing on this. Is there a way for me to find out what causes(ed) this wakelock on my s4 so that I can troubleshoot that thing and make any reports needed to the respective people to correct the problem causing it?
I have kindoff the same problem

I also have the same problem with my s4, I installed greenify and DS battery saver but they don't help. My device wont ever go into deep sleep!
I am on 4.3.1 and the thing is that I have something broken on my modem too, so maybe my situation is different. So I'm trying to use my device as a tablet but my battery gets eaten away like hell.
