I am sorry if this was already found.
I know alot of people were complaining about the wifi shutting down when the screen timeout occurred. I found a setting in Spare Parts that changes the wifi sleep policy. My NC battery died and is charging so I didn't get a chance to see how well it worked but hopefully it helps.
I set mine to never. I also found that a some of the lg apps posted elsewhere here install and work on the nook.
I for one cannot wait for the roms. This thing kicks serious ass in it's infancy... imagine if someone like cyanogen came on board.
Agreed.. Once Bluetooth is active and hopefully CM6 comes to play this puppy should perform quite well (mouse on screen ya!).. I'm amazed that the 3D games (mainly Gameloft) play so well right off the bat..
I did the same thing in Spare Parts and can verify that the Wifi stays active. I know because K9 on my NC beeps at me a second before my phone chimes when I get an email, even when it's been locked with the screen off for hours.

How does this affect battery life though? I imagine if Wifi is always connected and getting email, it should be a serious drain on the battery...
wifi on = battery drain

Yes it would so use judiciously.
I set mine to never turn off wifi automatically, and then I just use a wifi widget (either the power control widget that's already there) or Beautiful Widgets wifi toggle to turn it off when I'm not using it (during the day at work for example).
I have mine set to never...Still cuts wifi when the screen sleeps.
Any other tricks to try? I need wifi to remain active....

I've tried Wifi Lock as well as Spare Parts, and have the same result. Wifi still sleeps.
Spare Parts did not work for me either. I've yet to try Wifi Lock.
Wifi Lock works for me...
Ok.. I read all the posts I could find and installed Wifi Lock, this is the only one I tested and works great for me. (Tested using Pandora radio)
This is what I did:
1- Install Wifi Lock (Android Market)
2- Reboot Nook Color
3- Go to your Extras and run the app. (It doesn't have a user interface, it only displays a message every time you click on it: Default / Never)
4- If you are using Advanced Task Killer (or any other) make sure you deselect Wifi Lock and add it to your Ignore List (I did it right away, I guess that's a VERY important step)
I just tested it several times for about an hour using Pandora radio, I have no idea how much it will drain the battery... If something goes wrong I'll let you know...
Is this policy of keeping wifi on based on nooks that do not constantly reboot themselves, which is an issue many of us are having. there is a huge thread clarifying a partial fix for the rebooting based on killing wifi when the screen is off.
I am having pretty good results with "WiFi Manager" in the marketplace.
never mind - my bad, info was not correct, so sorry

If you don't set your wifi to never sleep, then when it DOES sleep it will scan. Scanning is a battery drain. Wifi never sleep is better.

This is absolute nonsense.
Wifi never sleep is a massive drain on the nook battery. Its better on a phone because when the wifi shuts off the phones data turns on and uses more battery. The nook has no data connection so when wifi is off it uses next to no battery life.

Thank you. My bad, I apologize for the bad information.
My problem was a bit different than everyone else's, because when my wifi shut off during sleep, I would have to manually reset my router in order to get the NC to recognize it. Needless to say, this was a huge pain, because we have a lot of devices in our home depending on the wireless router, including our cable boxes.
So, I've been using WiFi Lock on the NC for the past two days. So far, it's only lost the wifi signal once, and I was able to turn it back on within the Nookcolor. Hopefully this will last, because I will gladly take that over having to reboot our rooter.
I would like to pass along some info on an app that I “highly” recommend for controlling the Nook Color’s WiFi. For the last few days I’ve been using “Green Power FREE battery saver”
The beauty of this app is that you can control the “automatic” ON/OFF of WiFi based on when the screen turns off. With it setup to turn off the WiFi with a 0 second time delay I have eliminated all random reboots when the system goes into sleep mode. Also as soon as the screen comes back on it automatically turns the Wifi back on, and my Nook reconnects in about ten seconds. I have tested this in both Infrastructure and ADHOC modes (tethered to my phone) with no problems what so ever.

I have tried Wake Lock, Spare Parts, and WIFILock. I saw the most success with WIFILock but it has been failing lately. I'm going to try Soft Locker next and see what happens.

The Nook wifi problem sounds very much like the issue the ZTE blade has, I've made an app that creates a wakelock whenever you turn the screen off (if wifi is enabled).
Let me know if it works!

My friend is having problems with her galaxy s battery going flat even when not in use in about 20h (without using it.)
Any ideas
I checked for running aps
What might i try
Or is the battery faulty?
Can you help
it is normal if you enable data

yup it's normal
cheers for the replies.... but i don't understand them
what does she have to do?
I have the same phone, and make phone calls and surf the web and still have more battery in the evening.
her phone is just in her bag all day?

What apps does she have installed which you don't?
For example, if she uses the Facebook/Twitter apps and they're updating themselves every 10 mins as opposed to every hour (or even manually) then her battery will get eaten alive!

how do i do that? in the task manager?
I also turned the sync to her facebook app to 'never' .
Turn GPS off when not needed and WiFi when not needed that usually helps. Also when wifi is on turn off notify me about new networks. Make sure screen brightness is set to automatic also.
if she has live wallpapers thats a bad ideea for a lasting battery, live wallpapers use cpu.. cpu user electricity, and the battery gets empty really fast. i`m runing ~ 40hours with nonstop wifi or data mode activated, depends on my locations, 1 push email runing 24/7 skype 24/7 and i talk for about 10-30 min per day... so... install cpu temp v2 and uncheck the screen timeout (set it to 10 minutes) and let the phone on the table and look at the cpu tempv2 if the cpu drops to 1-5 % @100mhz , if it doesn`t drop below 10 percent @100mhz then you have some nasty apps that are not idle.
if im in an area where i get 5 bars i can get more battery life while using my phone for a while, than I would if I am in an area where i get no connection or an area where my connection is constantly dropping. This is because the phone constantly tries to connect to the service provider and uses up tons of battery doing it.

Go to Settings -> Applications -> Running Services and check what is shown.
(Switched my phone to English language to ensure the names above are correct). Do the same if your language is not English and you are still worried.

I have 2 days battery life with medium usage, download a stripped rom and keep it basic on the widget/wallpaper/amount of apps.
Download damiangto 1.2 gold underclock to 800 mhz (or keep it at 1000 mhz, but it doesnt change so much in speed for me)
undervolt by steps. as long as your phone doesnt die in sleepmode you can go lower. Im undervolting at -100 without any problems.
Download superpower or juicedefender. I have good experiences with both, using superpower at the moment and its free and good.
black backgrounds and themes are better for battery life because of the Super AMOLED screen.
You dont have to totally discharge your phone before charging it, charging whenever possible is actually better for long term battery life.
Hope this helps
Thanks for the replies everyone
I'l check all of the information out
I installed
Battery mix (has discharge graph)
Smart battery
Battery eta (has Discharge rate)
I swapped batteries with mine (hers still discharged too fast)
annoyingly it mucked up the battery discharge statistics because my battery was full when i put it in her phone.
She doesn't really muck about with her phone, very few apps or wallpaper etc.
I just go crazy with mine.
my battery discharge (with loads of use see CPU graph)

her battery use (phone was in her bag not used all day at work)
she was in a different location to me. see no CPU activity either
I looked in running services
mapslocationfriendservice (latitude) was 26% mine was about 9
and android system was higher on her phone
I mucked about unnistalled and installing maps using market and titanium backup
also I installed OCLF on her phone (one click lag fix) because it is on my phone. also the battery apps were slowing it down.
In short
her battery is plummeting about 3 hour if its in use and 11 in standby
its not the battery
i think is something to do with the android system.
probably latitude
but i could be wrong
I'll have another crack at it later.
Worst case i could master reset and restore titanium backups of her texts and contacts and stuff. but I like to sort it out
Cheers for the advice, I'll check it all out.
I'll post back if there any change in the situation
quick update
Her phone appears to be running better
I think it was google maps latitude update.
I cant 100% be sure.
but the result of the stuff i tried on the above post seemed to have changed her phone from the poor performance it suddenly started getting.
I am thinking of trying out 'superpower' and or 'juicedefender' on mine and her phones in the future.
Thanks for the tips everyone
I need help with this. I have noticed that my phone battery lasts a very short when is on a 3g network, using or not data traffic
To prove this, first i left my phone before going to sleep, on 3G network at 100% and Stamina Mode On, but after 6 hours the battery go down until 82%(6 hours and 37 min sleeping). I made the same experiment but in "Only 2G" mode, and the battery go from 100% to 98%.
Also i've made the same test on 3G network and NO Data connection. Results, 100% to 80% in 7 hrs.

Finally and following the advice of an user from sony support forum, i did a factory reset using PC Companion(12.0.A.2.245). So, no root, no applications, no sync with google, no nothing. I left it at 100% and dropped to 82% in 7hrs on a 3G network without data connection.
Besides, this problem causes the projections of battery life do not change when you turn on Stamina Mode. I mean, Stamina Mode works(disable data connections) but there's no differences between have data or not, the phone uses the same battery.
So it is not normal that battery consumption on a 3g network while the phone is idle. I've made some screenshots and as you can see, the process com.sonyericsson.android.wakeup, has to many wakes. I read about this en xda-forum and is seems to be related whit Fast Dormancy, but not sure if that's the real problem.
I lost the screenshots when i did the factory reset but can see in this thread of Sony Support forum: Sonymobile forum: 3G and Battery Drain
I hope you can help me. Greetings
PS: sorry my bad english
Only thing I can suggest it's leaving WiFi on. This consumes less power when idle.
Really confused by people's problem with the battery, in use its average, but stamina mode works perfectly for me.

The 3G radio can be one of the biggest wasters of power in a phone especially if you are a long way from the cell tower or your local cell is very busy. Even when your local cell is close, when it has a lot of simultaneous connections the signal strength goes down and your phone continually tries to reconnect, in order to remain on the network, using full power.
If you are lucky to live or work near cells which don't get very busy, the 3G radio reduces its power output, and probably also doesn't have to reconnect as often.
Still, your case sounds a bit extreme, so maybe there is something else involved exchanging background data when it shouldn't be.

Thanks for the answer.
I thought the problem was the signal. So I checked the signal strength at the place where I did the tests and the results were that the signal is between -75 dBm and-85dBm. That's a good intensity. Besides I live in a small town, so I doubt that the local cell is very busy.
I think that's because the fast dormancy. Are you root? Try installing betterbatterystats and see what processes are draining your battery. In my case I had to delete de fast dormancy apk and it solved the issue.

Yes, that's one of the first things i do(fast dormancy)...and not solved the problem.
I don't think is related with the battery, because in 2G, the battery works perfectly. The problem is related to the Phone Radio. :crying:
As many of you suggested 3G is another way saying 3 times faster battery drain!
Use wifi unless you are on the go in this case if you have to use 3G

But Wi Fi is useless to make phonecalls. My problem is not related to the traffic data on a 3G network. The problem is the standby in a 3G network without Data and wifi. As you can see in the screenshot below, the phone radio consumes too much battery on stand by mode.

Thats a real problem .... it may be a software issue!
I was a big fan of the battery, but updating my software killed deep sleep. Wiping everything and installing from scratch fixed deep sleep.
3g is a big drainer, but stamina mode should turn 3g off when the device is idle.

Thats the problem, Stamina turn off 3G data connections(internet), but 3G phone radio(calls and sms) keep working and draining battery. So, stamina just give me 2 or 3 more hours of battery, not 4 times more battery as sony promised.
By the way, the specifications of the phone says: Stand-by Up to 635 h (2G) / Up to 734 h (3G)
go to settings>data usage>click three dots of the right top corner and click on the "restrict background data and auto sync" might helped ur problem lil bit.

Yes, I tried that too. But as I said before, the problem is not battery consumption using internet. Is what it consumes wcdma radio to stay connected to the cellular antenna, make calls, or data traffic.
Notice the difference after 7 hours standby:
2G --> 0,1%/Hr
3G --> 2,6%/Hr
I have also having same problem.
Turned off data and wifi. set only WCDMA network, enable stamina mode.
The battery drop from 100 to 84 within 7 hours.
Check the battery usage, the Cell Standby occupied 54% of usage.
Still havent test for 2G. If really 3G problem, then i will just stick with 2G when im sleeping ><
BTW, my galaxy note N7000 battery drop 0%-2% while im sleeping with using 2G network (off data wifi)
*Yea, the battery drop 0% after 7-8 hours
to reduce the number of wakelocks for fast dormancy, root your phone, then go to /system/etc/fast-dormancy and open fd_custm_conf.txt. replace the '0' of the 2 lines with the MCC and MNC numbers of your APN respectively. you can find these numbers under your Access Point Names. just click on the one that is active and scroll down until you see MCC and MNC. once done, save the file and reboot.
it works for me, the wakelocks have decreased but i still get a huge battery drain in standy mode, with wifi on and stamina mode on. hope this fixes the issue for you. cheers :good:

Sorry to jump onto this thread with a question that doesn't help you solve the battery issues, but I'm guessing you guys will have a good idea of the answer to this.
How do I set 2G only? The only options I have are: 4G (preferred)/3G/2G, 3G only, or 3G (preferred)/2G.

Some firmwares don't let you do that. But you always have the option to do with the information menu. Just dial *#*#4636#*#* and then go to "Phone Information", there's an option to set the network type. :good:

Thanks, I did find that one, but it's a bit too much for my wife to do regularly. Once it's out of warranty, I'll stick a different rom on there. For now, she's getting 2 days, so can manage with that.
This is not another, I love this phone BUT the battery is too small.
Currently there is a massive bug affecting the T-Mobile (possibly others) Galaxy S6 (unconfirmed on edge)
Symptoms
Massive Battery Drain while Idle
Cellular Standby top Usage in Battery Stats
Random WiFi issues
Self Diagnosis
Go into Battery
Tap Cellular Standby and remember the "Total Connection Time"
Go back to "Battery" and hit refresh
Check Connection Time again
If the time increases but you are NOT using any applications, on the phone or downloading you are affected by this bug.
Fixes
Turn WiFi calling OFF
Disable VoLTE (VoLTE toggle is in the Phone App/More/VoLTE.)
Update - Turning off WiFi Calling along with disabling VOLTE appears to have patched this issue for now. You can still use WiFi like normal and turn that off and on and it shouldn't have any issues.
So lets discuss this, I have not been able to fix it. WiFi on or off, WiFi calling enabled or disabled nothing seems to correct the problem. Its as if the phone is ALWAYS on a call.
Edit- VoLTE seems to have corrected the issue somewhat. What I did is turned off VoLTE, Turned off WiFi calling and then turned WiFi off and back on. My Connection Time hasnt moved since. How long this patch lasts for, I don't know.
Mods - Please monitor this thread if you could for battery naysayers and complainers. We are out to diagnose and fix the problem, not complain about it.

Thanks for starting this thread. I have tried pretty much everything, including uninstalling/disabling most apps, turning off "keep awake" for what's left, etc. I just tried turning of VoLTE and I still lost about 2% in 15 minutes with my phone just sitting on the desk (no use). My next course of action is to try a wipe. I really don't want to take this phone back. I still think this is some sort of bug with 5.01. My Nexus 6 had battery life issues until 5.1 and now it's awesome.
Okay the VoLTE trick fixed my high cell standby drain.

I've used quite a few lollipop builds and I've noticed on just about all of them (including the s6) Google play services runs pretty high. Haven't had the phone long enough to accurately test, but I'd suggest for those seeing it run pretty high to completely disable auto update of apps. That should help limit its ability to wake up the phone.

I actually disabled wake for that app using App Ops. Nothing in Gsam or regular battery stars is telling me anything.
I just performed a wipe. If that doesn't do it, I give up.
Ok guys let me throw in my 2 cents.

that was yesterday usage. I had wifi on the whole time yesterday.
Now today usage wifi off since 100%, i have no ****ing idea why facebook is using that much, ive use it 10 mins at most.
Facebook is like a hydra when it comes to app permissions. It has the most permissions to your phone with few apps to rival it. Use an app that blocks particular functions you dont use in the facebook app (GPS, contacts, etc) and just install this (must be rooted) https://play.google.com/store/apps/details?id=com.findsdk.apppermission&hl=en
I realize it hasn't been a full days of use yet, but the Cell standby sums up the battery issue drain. I'd prefer to keep VoLTE on, and we should be able to without this being a problem. It was on, on my G3 and I didn't have such significant Cell standby battery drain. Any idea of another cause?
So, I finally caved in and wiped, even though I have had the device since Monday and battery has been bad all along. Prior to wiping, I was losing around 2%/15 minutes (8-10%/hr) without even using it. After wiping, seem to be losing around 4%/hr. I am not using it at all, just testing the idle drain. It's definitely better.
My question to the fine folks here: Does 4%/hr with no use seem reasonable? I only installed minimal apps and none of them are doing any kind of autosync or update. I have one exchange account set up through Nine and then my gmail account.

Prior to wiping, I was losing around 2%/15 minutes (8-10%/hr) without even using it. After wiping, seem to be losing around 4%/hr. I am not using it at all, just testing the idle drain. It's definitely better.
My question to the fine folks here: Does 4%/hr with no use seem reasonable? I only installed minimal apps and none of them are doing any kind of autosync or update. I have one exchange account set up through Nine and then my gmail account.

4%/hr completely idle still seems high

For me, even without ever turning on my phone, it's syncing with breaking news apps, facebook, twitter, hangouts, gmail push, work email push, a couple online RPG games pushing me alerts and so on. My battery drain ironically isn't stemming from apps syncing and emails/alerts being pushed constantly throughout the day. It's the cell standby for me.
contributing factor?

Seems to be the cell standby for me too. Disabling WiFi calling and VoLTE has fixed it for now.
Is there a Samsung support channel where we could get this recognized? It seems really asinine that people are exchanging the handset for what is clearly a software defect.

VoLTE seems to be my problem for now. Disabled it. And fully charged it to 100% and its now at 75% and cell standby isn't even on the battery stats list.

So, I can't believe I'm saying this, but a factory reset totally resolved my battery issue. It was only 4 days old. I couldn't see how it could have possibly been fixed by that, but it was a last resort before returning it.
Now I have some pretty normal Battery life. I love this phone!

If you hadn't been a douche in your follow-up reply, I certainty would consider it.
Having this issue as well..after having a nice battery cycle of almost 5 hours sot I'm seeing the same thing in bbs, losing 6% an hour idle. Will try the fixes to see if it helps thanks guys
so im getting the edge on the 15th
should i factory reset it right when i get it ?
The only thing I did out off the box was take the OTA and root. Maybe the OTA set it off? I pretty much have the same apps installed now.

So I use WiFi for about 95% of the day, and it appears the verizon models suffer from cell standby... I have smart network switch turned off as well. My screen on time at the moment of this picture was 1.5 hrs. Here's a picture

Not sure it's an issue
Cell standby is also the main cause of battery drain in mine, but I'm not actually sure this is an issue. Something has to have the highest impact on battery and it makes sense that it's cell standby because that's the only thing that's on constantly (unless airplane mode is on). The actual battery performance seems to be as advertised, so I'm not complaining.
It makes sense... 2 radios drain the battery faster than 1. WiFi is only to save on your tiered data plans imo.
I believe I saw that if you disable VoLTE or Enhanced 4G that this symptom goes away.
I was reading through the AT&T S6 Edge forum. I'd post a link, but I wasn't able to locate it again.

Isn't VoLTE disabled by default on Verizon phones under the alias of advanced calling? I haven't seen a menu for enhanced 4G either...
End of the day stats are hovering at around 3 hours and 20 minutes screen on time with 12% remaining, auto brightness with cell standby at a whopping 54% while my screen is at 8%. The hell?

VoLTE has nothing to do with it, tested 3 days of VoLTE on, and 2 days off. No difference, and my Cell Standby usage is up in the 40% at the end of every day.
I noticed that as soon I conenect to wifi stand by start to raise, disconect and stop, is kind of weird
problem fixed!
The fix was this:
1) turn off phone
2) hold volume up, home button, power button until it boots into recovery
3) wipe cache partition
4) reboot
5) turn ON advanced calling
I was able fix my battery drain problem. Most forums will tell you to disable hd calling but on the verizon model it is off by default. Turning it on and clearing your cache fixes the cell standby issue. When you turn it on it will ask you to activate. Don't worry, its free. My battery life went from 6 to 14 hours with heavy use.

This doesn't wipe the phone or make you redo anything does it

No it does not affect internal memory (pics, music, etc.) or apps. @ humblesheep I was pretty amazed by how much of a difference it made. There are a couple of other things you can do as well such as disabling location services and bloatware apps that can increase battery life.

I just wanted to say thank you. I have been trying to figure this out for days. Can't wait to have a good battery life!
Fix for cell standby bug is to go to Settings > Wi-Fi > more > advanced then make it look like this.
This is for the people that are having issues with the battery draining while on wifi only.
Setup like image below and it should fix your issues.
worked for me, I think

I did this an dumped a couple apps that I had downloaded. But I think this is what finally did it. Standby was at 50% most of the time and I couldn't keep the phone charged, and charging took forever. The standby has been at 1% all day. I didn't do the advanced calling part. I couldn't figure out where that was, but it still worked.
I've tried this several times but it doesn't seem to help. Could it be because I'm rooted? Cell standby is completely murdering my battery. Today it used 41% of my battery. Any other suggestions?
i did this and my cell standby got worse but a lot (went from 5% to 20% after that process) any suggestions on what happened? i followed all the steps

I had this issue when I first got my phone. The battery was terrible when on wifi at home and great with wifi turned off. Eventually I signed onto wifi while at the office and the issue was gone. Once I figured out my home router was the issue, I created a guest network on my router where devices couldn't talk to each other. After I joined that, battery life was then good at home.
I did a network capture and found that my Plex server was constantly sending out broadcasts, which may have been keeping the phone from sleeping properly.
