For those of you unfamiliar, JuiceDefender is a tool which toggles WiFi and Data when the phone is off, and turns on WiFi only when in a location where there's an accessible network. This software more than doubled my battery life on my Bionic, and so it was one of the first things installed on my phone.
I've noticed JuiceDefender has been sucking a fair amount of battery on ICS/GNex (usually 4% in the battery graph), so today, for an experiment, I uninstalled it for the day, and I've noticed that I've gotten better battery life than I ever have with the phone, across a mix of WiFi areas and 3G.
Has anybody else had this experience, or was this just an odd one-off situation? Could there have been a change in ICS which diminishes the need or hurts the usefulness of it?
I've had JuiceDefender off too and for me I seem to get slightly worse battery without JuiceDefender. Without JuiceDefender on I tend to get a steeper battery drain during idle times compared to leaving wifi and 3G on. I think the usefulness of it depends a lot on your usage habit and signal quality as well. I usually get spotty signals so that is probably why JD helps noticeably.
Interestingly though if you take a look at the battery graph in settings, every time JD toggles your data on it seems to force the phone into awake state, but just leaving data on would keep the phone in an idle state most of the time. That's definitely something that is making JD not as good as if should be.

Honestly I think the only time you get noticeable battery improvements with juice defender is with periods of no use. Which is why it works good for me, on work days that is

Totally agree with this.
That's odd, as for me, the phone is mostly in my pocket all day. Maybe it's because I've got a 15 minute synchronization time for most things?
Day three without JD, still getting twice the battery life that I was getting with it on. Delightful.
I don't like any Kind of app that claims IT saves battery life because it just doesn't work! Fact is that its just another apps that sucks resources out of your phone!

Going to have to disagree and while there are many variables juicedefender can offer big saves depending on your usage. I have had 1.6x increase as stated in the app and confirmed by the extra hours with the incredible. I am waiting to try it with the GN until I have a idea what battery life is without it. First week is useless anyways with a new device as you check it more often and the OS is still refining the battery meter.
Its all related to how you use your phone. Disabling Wifi, Data, BT and so on automatically, managing autosync saves battery. The app itself sucks almost no battery power - if i can believe my monitoring app (SystemPanel 1.1.1) which i use unfrequently to control app behaviour on my Galaxy S1 (with ICS and before that, on GB). Im taking up this "Old" posting because i have battery issues on ICS - almost half of the lifetime after upgrading from GB. But i think its because im now more playing around with the phone, no app is sucking more power than usual.
I noticed that JD cant control networking (via apn change) anymore, can somebody confirm that? If i turn the display on, my 3G/HSDPA connection is there - under GB it took 3-5 seconds until i had internet connectivity back.

Mine has been terrible for awhile. Even Odin back to stock and it wasn't any better. Now I'm on a clean flash with very little installed and I've only seen minimal improvement.
Here are a couple of screenshots from this morning looking at while I was sleeping. Lost 25% overnight. Had an hour of awake time with near zero screen time, seems like a lot of battery lost
You're letting way too many apps sync in the background, your phone is not reaching deep sleep. I bet you left your Google account on auto sync. Your email is syncing too often. don't leave wifi on overnight. You're getting poor signal too.

I've always let my Google account sync and left wifi on at night. It just seems like the last month or so it's chewed up lots of battery. Heck with my old desire it'd only use 3-4% (with basically the same setup) overnight.
I had this problem and was able to fix it by repeatedly throwing my battery on the sidewalk. It helps to re-excite the electrons in the battery and improve battery life.
I am trolling, in all seriousness, lithium ion batteries significantly reduce in capacity over time. It is perfectly normal for the battery to last 25 to 50 percent less long just a year in. Pro-tip, you can find replacement stock batteries on Amazon for about $10, just make sure it is an OEM battery. If you are nice to the tech or store manager at your local sprint corporate store, sometimes they will give you a replacement battery for free.

Thanks. I'm with us cellular and the phone is only two months old. They do have a battery swap benefit, but I think it can a crap shoot on the quality you get back.
I un installed that hacked s-voice app, that seemed to help quite a bit.
So it must be something with wifi. Had wifi off all day yesterday at home and last night (just using 3g connection) and I only lost 2% overnight. On 16 hours with an hour of screen time and still at 79%. Not seeing the wake ups and wakelocks like I was before.

Sounds like you've got apps set to sync when on Wifi only then. To confirm, try leaving Wifi on but turning off background data. If your battery life improves, it's definitely an app. Then you just have to go through your apps and figure out which one it is.
Gmail can be set to push so you don't have to worry about it syncing unless necessary. But if you get a ton of emails, it's still going to hurt.
Also, I disagree with revamper, if you get poor signal you should leaving Wifi on as much as possible. Being connected to solid Wifi will drain less battery than your phone constantly polling towers for a better signal (given identical app behavior, which you don't have atm). I'd still turn Wifi off when moving about, as you won't be on a single, solid Wifi connection and you phone will be polling both towers and Wifi networks, resulting in increased battery drain. You also want to set Wifi Sleep Policy to not sleep when the phone screen is off (otherwise as soon as you turn off the screen Wifi is disabled and you're polling towers again). From what you've said, it sounds like this is already set though.
The best thing I've ever done for my battery life was flash Calkulin's ICS ROM. 4 days of standby or a full day of some really heavy use. Email is the only thing that syncs automatically (push). Other apps like Facebook aren't that important to me so they only sync when I open them.

I had a battery cook in the phone this weekend and this is what the sprint tech did. I picked up my phone after being on the charger overnight and it was almost hot enough to burn me. I took it in, they popped it out and spun it like a top... Handed me a new battery within 5 minutes.
Yeah it's probably wifi. I also have much higher idle drain on wifi than 3G right now, although I haven't had time diagnose it. Actually, I hadn't bothered because I was planning to move to an AOSP ROM from stock ICS once kernel source was published, but I'm losing my patience. The AOSP guys seem to have things worked out without source anyways.

I also have extremely high drain while on wifi, I just made it so the wifi shuts off when the screen shuts off
I've had my Verizon Galaxy Nexus since launch day. I've NEVER been able to get more than 3.5 hours of screen-on time with this thing. But lately it's been even worse. I'm seeing anywhere from an hour to two hours before I have to reach for a charger, usually right around 1.5 hours of screen-on time. It will sleep for a good long while (no wakelocks causing drain that I've found).
I keep sync on for some Google services, like Gmail, but not many. Battery life doesn't really seem to change regardless of using 3G or LTE, nor does wifi seem to improve. When the phone is awake, and the screen is on, the battery just drops like a rock. Literally every time I look at the battery percentage in the status bar, it's dropped another 1-2%, even if I'm not doing anything.
I've run everything from stock 4.0.2 to AOKP JB nightlies (which I'm currently running, with imo's kernel). I've tried practically every ROM/kernel combo out there and never seen an improvement. I've undervolted, underclocked, played with brightness settings, everything I can think of. It's been wiped, the battery has been occasionally cycled, etc, and nothing seems to improve the battery life--it's only gotten worse over time. I did, at one point, have an OEM extended battery, but it wasn't a significant improvement enough for me to get over losing "the hump" so I got rid of it (actually traded it for a Droid X, lol).
So I'm kind of at a loss with this thing. Does the battery really suck this much? The other day, a coworker with a Galaxy S III on Sprint used his phone for over 3 hours of screen-on time (I looked at his battery stats) leaving him at about 35% battery. Mine was also at 35%, with only 1 hour of screen on time. I understand the GS3 gets better battery life in general, but this is getting to the point of being unacceptable.
Not unusual. Big screen = big power requirement. Poor reception (i.e. bad coverage area) saps the battery the quickest, extended screen time on is a close second. Have you tried the extended battery? It adds enough to get well through a work day and commutes if you're not using the phone as a laptop. However if the phone is being used as a laptop, I'd suggest buying an actual laptop, or better yet a tablet. I get 10 hours of steady use out of my Xoom.

The phone doesn't have amazing battery life but what you're describing sounds pretty abnormal. It may be a bad battery.
Yeah seeing as the battery is around 9 months old, I would first try and get another battery and see if that makes a difference. Most batteries dont go bad that quickly but wouldnt be surprised if it did. Worst case you would have an extra battery that you can also keep fully charged as it seems though you have tried most everything you could regarding any software issue.
I noticed my battery life is terrible. My phone is only like 5 weeks old. I've tried the battery saver apps, power-saving, and pretty much every other tip. I start off with 100% in the morning with brightness turned down and everything else and I mainly listen to music more than anything so the screen is usually turned off. It still manages to go from 100% at 7:30 to about 17% at about 4:30. And the phone is turned off for about 3 of those hours. Also the other day I started playing TDKRw/100% battery life at 7:30 on high brightness and power saving was off. At 10:00 the battery life was at 15% not to mention I paused the game a lot. Is this normal at all?
Seems ODD. My phone is like that as well but one thing that i noticed is turning off cellphone data. that helps battery life big time. try that and see how it goes.
The TDKR, would be normal, the high end games just gobble up power, often even consuming more power then a charger can keep up with.

I was like that when I bought my phone, but after playing around with some ROMs and kernels, I found what's working for me - ParanoidAndroid + Ktoonsez kernel = 2 days moderate use and over 5 hours screen time with 100mV undervolt
OP might have bad reception too, that'll eat your battery up
Reception is a killer battery eater.
Especially for me, just moderate texting and some short phone calls will drain my battery.
It's because where I live, the signals are fairly weak and I will get EDGE or 3G data most of the time.
Additionally, check your wakelocks. Sometimes applications run during when the phone is supposed to be asleep. Getting a handy battery measuring app will help.
Also try turning off sync or turning your settings for e-mail, google services, etc. to manual so they won't run when you're not using the device.
Otherwise, the forums probably have dozens of posts with tips on increasing your battery life.
There are many battery threads, true. But as of a day or two ago, you only need one!
Woodrube ported his thread over for us. I highly recommend evrryone take a few min to read it!
http://forum.xda-developers.com/showthread.php?t=1969741
For those of you with poor signal and wind up on Edge, turn on wifi if possible. It uses less power than your data connection, plus, by having it on it disables mobile data leaving only the voice connection which is much easier to get a strong signal for. So in every way this could help with battery savings.
Even if you have a great signal, your wifi will still use less power. I always connect to eofi when I'm able and the sleep policy is set to always stay connected. If you set it to disable while asleep it simply will activate mobile data in its place.

Sorry for the slow response. Haven't had time to get on here. Thanks for all the help though. I was mainly scared though because I heard some of the phones had a bug in them to where it drains the battery life like crazy. I think that woodrube thread will help me tremendously.

The only thing about that is, I barely make phone calls or text at all. Like I might text 3 times day and make calls like 3 times a week.
Does anyone have any tips on listening to music. I use PowerAmp and I probably use my phone mostly for music.

I use TTPOD to listen to music,its free for the full edition and has great equalizer....
I hate to be the guy that asks this, but I just want to make sure as from what I understand this is different from phone to phone. From what I understand, Li-Ion batteries, like the GN2's, do not have a memory effect of any kind? And thus all battery calibration rituals and nonsense are entirely pointless for this handset?
The reason I ask is because I wasn't able to charge the device to 100% before use like I was always told to do with new phones. My device was turned on and used until it drained to around 10% at which point it was charged to 100%.
Now, after 2 weeks of use, I feel that my battery is not as good as it should be. I'm barely able to get more that 12 hours. I'd be happy to post some battery graphs in the morning.
One last thing, if I did mess up my battery, or if my battery is messed up or less functional than it should be, would buying a new battery fix all my problems?
Youvare right. All that calibration stuff is nonsense.
I have never charged my phone to full before using and draining the battery and my phone still lasts all day on mostly heavy use.
Could you post your batt stats?

Today I ran my phone with the "lowest" possible settings, that is lowest brightness, CPU power saving, and no haptic feedback. I did not turn off wifi. Doing this I was able to get a surprising 16 hours, although you can see from the graph that I didn't use my phone as much. Attached I have a screenshot of what it's like with the highest possible settings (no power saving stuff, and brightness all the way up, but no GPS). Sorry I don't have a pic of the percentages for the high settings, I never thought to do that.
What concerns me the most is this: even with the lowest settings, I'm only getting 2 hours screen time. (last pic)
What's interesting is that you would think that if I'm getting such poor screen time, there would be something else using a lot of battery, but there isn't. This led me to believe the problem was with the battery. I discovered a pretty big scratch on my screen the other day, and I have some monthly insurance plan from best buy, so I was thinking of just getting a new one. The longer I wait to get a new one, the harder it will be to set up everything again. lol
I noticed that compared to other GN2s, mine seems to wake up a lot when the screen isn't on. The awake periods tend to correspond with drops in battery and also when I have a poor signal. Could this be caused by my phone trying to look for signal and using battery?
Yes poor signal that results in the phone searching for better 3g/2g will drain the batteey faster.
Can you try using it in airplane mode with wifi only for a day and see how that goes?
Also install Better Battery Stats and after a day or so of normal usage check your partial unlocks to see if a rogue app is preventing deep sleep and sucking your juice.

Dude you have major wakelocks that eat up 80 % of your battery!

K, I agree with my week signal using battery. I only have 75 apps on my phone and they're all pretty mainstream, no obscure apps. Right now im in school with 86% battery, I'm turning on airplane mode now. I have noticed however that when I clear my ram it closes like 50-60 processes each time. I am always closing my apps, but 50 seems extremely high. im gonna turn on airplane mode and see how that goes...
thanks!
Yes, you do have poor signal but that's not all. You have terrible wakelocks pal. Install BBS and monitor which apps are the culprit. It's not about 75 apps, even 2 or 3 bad apps, which have hidden advertisement going on could suck your battery flat in no time.
So first thing, install BBS. 2h screen on time is horrible!
Btw- If you're on 3G, try to switch to 2G. Difference will be unthinkable.

Thanks everyone! I'm really loaded with school work, so I don't have a lot of time right now. But long story short, airplane mode saves my battery like crazy. I started school with 86%, turned on airplane mode, and I'm at 79% right now! more later
Is it safe to say I fixed it?
3h screen over 2 days isnt bad right? Perhaps just a bit worse than what others are getting?

Hello guys.
I've been reading these forums for a few months now and find it very very helpful in configuring my device. It's just now that i decided to sign up so i can be part of this great community.
This is my first ever post and i would like to get help regarding my battery life.
Ive read a few articles about battery saving and also from forums where people usually get more than a day's worth of battery life. That got me wondering why i only get around 8-10 hours average considering i only use it very lightly as im usually busy at the office. My actual usage time range about 60% of those 10 hours when i use the phone during breaks.
Here are example screenshots of my daily usage:
Here are some details about my configuration:
Brightness set to auto, most of the time at 75% level
Wifi, bluetooth, gps always off
Haptic feedback set to minimum
Mobile data always on and set to WCDMA only, area where im at is usually weak peaking at 2 bars of H and H+ signal strength
Gmail set to push notify
A few apps and widgets set to sync after every few hours(accuweather, flipboard)
Ive been considering getting an extra battery because of this but i really want to make sure first whether i could still do something or whether im doin something wrong thateads to the battery draining too fast.
So please if you have any more tips i could use, please help me out on this.
I thank you in advance.

Their battery lasts whole day long. It means that they get 10 hours of screen on time only. Not 24 hours.
Sent from my GT-N7100
Yeah. But in my case the 10 hours is the total life of the battery from the time it is charged until it dies. I'd be lucky if i even get 4 hours screen time out of it.
Do you have an idea why this is so?
Im guessing its because of the weak signal where im at and the fact that i set my phone to search for WCDMA only. Although im not sure whether this is really the culprit. I'll try setting the network mode to auto for now and see if anything changes.

Looks like it.
Try better battery status.
Sent from my GT-N7100
Well after i changed it to auto it improved a bit. Its currently at 14% after 11 1/2 hours with 4 1/2 hours of screen on time. The phone stayed on full edge signal for most of the time (which kind of sucks because internet became painfully slow on edge).
But still, i think this is far too short when compared to those who can get it to more than 24 hours battery and more than 10 hours of screen on time.
Is it possible that i have a defective battery?

i got exactly the same problem, whats your firmware?
since i updated the phone to 4.1.2 the battery drains alone, every 8 hours it discharges 25% without using the phone, i am lucky if i get 5 hours of screen. The android os is the one draining all the battery in my phone. On 4.1.1 i could get 7 hours of screen time with 20+hours overall.

I can't compare mine to 4.1.1 because when i bought mine it got updated to 4.1.2 after a few hours.
having to charge at least two times a day really negates the otherwise great features of this phone.
I really hope we figure this out. I'll try UtkarshGuptas suggestion using Better Battery Stats and let you know what i find out.
I did they and found Google location services is the culprit.
I'm am referring to the locations services found under location setting in the actual Google maps app. I believe turning of location reporting may disrupt Google now features. Google locations devices is reading out as the main reason for nine consistent partial wake locks on better battery stats.
I'll try turning these features off and awe how it affects battery life and Google now tomorrow.

after doin some tests with bbs i found the wakelock is mhl_wakelock,
First off, forget all the battery programs. Factory default your phone and add an apk at a time and use. You'll be able to tell what apk is the problem with a lil testing. Slow process yes but pretty straight forward and to the point. I do have a Note 2 and have no battery issues being rooted and having tons of programs, etc. Basically, I use and abuse my device as per my job and still get a day and a half out of the battery.
People who can get 24hr coupled with 8hr screen time most likely have their phone on low brightness and on WIFI not data.
I got a new battery and its still lasts the same as the other. Yeah it may be because of the mobile data always on that eats up my battery.
Problem is my data connection is my primary internet source i dont always have wifi hotspots. So i might just have to live with the short battery life or learn to turn off my data when i dont need it.
I'll still try looking for other things that contribute to the battery being drained though.
Thanks everyone.

I have GPS disabled, auto brightness (but fairly high level) and that improved battery life quite a bit. I then changed kernel to NEAK kernel, reduced the voltage levels for the CPU and that further improved battery life. I can get a full 24 hours on one charge and with normal (?) usage). With the new kernel I can also modify the charging current to a slightly higher level which reduces the time to bring to a full charge.
All in all not too bad but to expect more than 24 hours is unrealistic in my opinion as it is a big handful of electronics!
Not sure what you guys are are doing different. This is my first full month with my note and the battery is a beast. GPS is enabled at all times but all other syncs are disabled. That's just from previous experience. Sync will always drain the battery. So mine is off. I went as far as removing all the extra chargers around my office and home. .now I only need one. And I alsi don't see a need for an extended battery unless I'm going to be away from civilization for a few days. By the way..that was the only time I've killed my battery..kinda. see screenies
--I forgot about brightness- mine is set to 50% and 4G/LTE ..if the device is always searching for it, it will kill your battery. I turn it off at the office as much as I can.
