I bought this amazing [As you all know how fast it is ] Galaxy Nexus and was previously using hTC Desire S[GB] !!!
I'm somehow not happy with the battery life and also the overheating of Nexus !
It is Stock[ROM + Kernel] + Root ! around 7th or 8th charge cycle !!
I did try out Cpu Sleeper App works like a charm but was facing reboot issue and that is why had to remove it !!!
See if anyone of you could help me overcome these issue ! or Is this really something for me to worry about !!?????
[PS: Please don't recommend me to change ROM or KERNEL ! Because I prefer to stay on Stock ! Also NOOO Overclockig !]
Check out the Few screen shots i took when my brain kicked me to !!!
We need to see the screen before this one(the one that lists top consumers of battery). To see if something is waking the phone up. Also, charge cycles and calibration are bogus. If anything, you would be using the phone less since you've finally set everything up the way you want and the newness effect has worn off. My battery life has been about the same if my usage pattern remains like it usually does throughout the day. It doesn't really look too bad, but the drops seem a little steeper than what I normally see. . Grab CPUSpy and BetterBatterystats. I'm on my way to work soon, but someone may be able to help you before I go on break.
the screenshots you required

Here we go
ok so calibrators and cycles are bogus ! I get that !
What about brightness ? Should that be auto or manual mode ??
And is Google Now causing issue ?? Because its not really useful to me on daily basis !!???
And any other suggestions your would like to share
I was gonna edit my post, actually. I've personally never fully charged and drained my battery for any of my phones(some people swear by it though). I guess if the readings are out of whack then yes. My phone got stuck at 85% for almost 12 hours one day, but I had did something which messed up the OS. Haha.
If you don't use Google Now, you can opt out of it. Brightness is a personal preference. I usually stick mine at 25%. Auto may take a hit on the battery, but I doubt it's anything to worry about. Just the common sense stuff. Apps that poll data in the background will drain the battery, but if they're properly coded, they shouldn't be a problem Running on 4G/LTE/HSPA with a bad signal will drain it more since the radio is trying to find the best possible signal. After a full day of use, what is your typical screen on time? 18 hours is pretty good if you're using it on HSPA all day.
ya honestly that doesnt appear to have anything wrong. What results were you expecting vs what you have? You have a lot of screen on time, that takes a LOT of battery to run the display and using it when brightness is high takes significantly more. Also it appears you have a couple long phone calls in there as well. As far as heat goes, youre going to have that on the higher end phones due to the gpu producing heat and oled displays produce a bit of heat as well, lcd runs cooler.
Weak/unstable/unrealible mobile network signal could cause the fast drain of your battery. I saw you have one bar of hspa signal in the 3rd screenshot.
Those graphs should be much flatter during idle periods. Something is keeping awake. If you're on jelly bean its prob Google now. It does it to everybody.

Actually 3G isn't really well established for Vodafone[or any other company] in India.Also there is a peak going upwards in the first image indicating charging and after having a battery life of around 20 hrs on My Desire S and screen on [appx.] 7 hrs , I'm very disappointed with Jelly Bean !! Also While googling this issue I found out that somebody sniffed the mobile wifi connection to monitor and found some app constantly exchanging packets which according to his test was the root issue for the battery drain !!
Edit:
]Ok I found the way to shut google Now !
I'll records stats for a day or two and get back Thanks Everyone for your time and help

In Google Now >> Menu >> Settings >> Google Now there is an on/off switch at the top. Depending on the ROM it's included as either velvet.apk or QuickSearchBox.apk but removing that would get rid of Google search I think.
Yeah. I think its actually part of search. Like I said, just opt out and you should be good to go. Keep us posted.

...and I've verified that the custom kernel was installed by going into About Phone. Is there anything else I have to do for the new kernel's advatanges to, well, take effect? I took off SetCPU since in the dev forum they were saying that the kernel itself will do what SetCPU did.
Sorry for the newb question. I've just rooted my phone and started researching a bit and wanted to make sure I didn't mess up or leave something out. The actual visual part of the phone looks the EXACT same as before I put the new kernel in.
I appreciate any help you give me in advance
I'd recommend you just use your phone like normal for a few days - if your phone is anything like mine, you'll see marked improvement in your battery life. The other day, with light use, I still had 30% remaining after 25 hours unplugged (without bump charging)... impressive!
I was in the same position a week ago. I installed Lou's #8 on my stock rom and it seemed to drain my battery faster. But I let it drain until it shut off and then charged my phone overnight. Turned it back on, and guess what? My battery indicator was stuck at 100% for like an hour. I thought it was a glitch, but it wasn't. That day, I had a 21 hour uptime... before I installed it, I could barely get more than 4 hours before having to plug in.

Does it matter when I allow my phone to discharge the battery completely? I will have to keep it charged and plugged in tonight because it's also my alarm to wake up to, but I'll have the battery dissipating all day tomorrow until it hopefully dies.

I don't think it matters. Mine conveniently died just when I was heading to bed that night. I do use it as my alarm as well. Thankfully, it was a weekend night.
Update: Running it today, haven't seen much change yet (but it's only the first day). However, how can I check to see what my battery usage is (I know you can check in "About Phone" but is there a numeral amount that would tell you guys something of significance)? Therefore if I posted something like that here people could tell me, "That really sucks, it's not working for you", or "Hey, working fine!"
Also, where I sit at work doesn't have that great of a cell reception, meaning maybe one bar if I'm lucky. Would having no cell reception drain the battery so much that it's almost dead by the end of the work day?
Would turning my wifi ON help the battery usage reduce some because the phone wouldn't constantly be searching for 3G?
Thanks again for everyone's help so far!
Wifi uses a ton less battery over 3g and low cell reception kills battery fast. Just let the kernel do its thing also letting the phone die is a bad idea. Our batteries aren't designed to ever fully die.

There are so many variables, I don't think there's any given number or threshold which will make us say "That really sucks, it's not working for you" ...
I've found that lack of cell service is the number one thing that will kill my battery regardless of kernel etc. I get between zero and one bars of (roaming) 1x at my house and if I set my phone somewhere that blocks the signal just a bit more, it can kill my batt. a lot faster. If your phone is using data throughout the day and you have a wifi signal available, I'd definitely experiment with leaving wifi on all day - that's what I do at home to have any data connectivity worth using. Using wifi like this doesn't seem to be too big a hit on my battery.
Also experiment with your phone to see if you can find a location or orientation which gives you a better phone signal - go to Settings -> About Phone -> Status and scroll down to see "Signal strength", this will be a number expressed as -dBm where the higher magnitude of the number (ie. -99 is a higher magnitude than -80) the worse your signal is. Keep in mind that this scale is logrithmic, so a change of magnitude of a few dBm indicates a fairly large signal strength change... So if setting the phone on the right side of your desk gives you -85 dBm and setting it to the left gives you -95 dBm, your battery will die faster with the phone set to the left... Keeping the phone in your pocket can really knock the signal strength down - experiment with the phone lying on your desk, check the signal strength and then cup your hands around the "bottom" end of the phone, covering the optical track ball and the buttons, etc... In my experience, just covering this antenna area like this drops my signal by 5 dBm or more.
One more thing which it sounds like you might be aware of already is that people report that due to small differences in hardware, these kernels don't work the same for different phones, so maybe trying a different one of Lou's kernels (or a different developers altogether) might work better for you (although trying each of the myriad kernels available sure sounds daunting to me). Good luck!
this phone sucks, you will have a huge screen but with automatic lighting seems drawn on cardboard, the reception is crap, my girlfriend with a lg optimus one has 3 notches and I travel to 1 here in the bedroom. And the absolute most ridiculous thing is the battery, are practically forced to go out with this and the galaxy's, fortunately, not yet sold, it takes at least 2 refills daily. Check it out and tell me if it does not sell a phone like this ****.

Congratulations on a useless post.
If that's the only battery life you're getting then you should really look at how you have your device set up. I easily get 12-15 hours on heavy use and more than 24 hours on light use (moderate use is somewhere in between). I use auto brightness, and keep bluetooth, gps, and wifi turned on all the time. I have facebook syncing and push email going and I have no battery issues at all. I suggest you take a look at your device configuration and also you may need to calibrate your battery.

Nowhere in what I posted did I say that. Try reading with understanding next time. What I said was I have everything turned on and I still get good battery life, so if yours is lacking perhaps you should take a look at how your device is configured. That a bit clearer for you?....
OP, your post has made my day today!
However battery life depends on how your device usage is. People with carefully set usage patterns can extract the most. For e.g. I use Locale to set a certain profile at night that switches off wifi, data usage, etc. That is one way to maximise battery life.
Edited your title to be proper.
Please maintain forum etiquette. You can get the same exact message across using proper language

Okay let me further clarify myself. When I say look at how your device is configured I mean look at what you have running. Do you have things syncing frequently in the background? Do you have apps installed that constantly wake the device? How many background apps are you running at once. I don't have any special configuration on my device. I have everything turned on as far as bluetooth, wifi, and gps. I use push email, facebook set to sync every 4 hours, weather set to sync every 6 hours, google reader set to "download frequently viewed feeds every hour", currents set to sync every 6 hours in the background (wifi only). With those settings my battery life is pretty good. When I'm not using my phone is drains between 2-2.5% battery per hour, that should give you a bit of a point of reference for what you should be getting when idle. Here's an app here I stumbled across that can show you what's waking your device http://forum.xda-developers.com/showthread.php?t=1179809 Hope this helps you out.
Battery is pretty good to me, under normal usage easily over 24hours.
I have had no problems with my battery or screen, not sure where your setup went wrong but listen to the posters before me and less ranting and maybe you'll make the best out of an awesome device
My battery is great! Better than any other smart phone iv used, signal is great swell and the screen is awesome
I love this phone lol

I see in your screenshot the GPS and the screen were on for most of that time.
And by "on" I mean the GPS was really on with a fix, not just "on standby" and ready to be automatically activated when a program requests it.
No phone I have ever owned has ever got more than about 4 hours from the battery when I have been using the GPS. The simple fact of the matter is the battery will discharge very quickly when using GPS. That's not a fault of the Nexus, that's just how it is.
Bad battery?
That screenshot shows you've been absolutely caning the **** out of your phone. Nothing will have a good battery life with usage like that.

I'm sure we all know that the battery life on the G Nexus is pretty awful, so let's all go star and comment on the issue so we can get Google's attention!

Just scroll all the way down to the bottom and star the issue or leave a comment too.
Done and done... I hope this comes before I need to return the VZ GNex
Hmm, compared to my EVO 4G, I barely had to do anything to this to get the battery life to be very good (estimate 100 -> 0 = 15hours). Maybe I use the screen less than you guys though.
At home, no LTE connection. 5.5 Hours.
On GSM.. battery life is stellar.. keep in mind, like the person who posted above me that if you are in a low signal area your battery will be destroyed searching for signal..
Yeah I don't have LTE where I am either, but I have it forced to CDMA only. Android OS is my battery killer. I usually get around 6 hours before having to plug it up.
I really think that if enough people starred the issue then it will get someones attention! (Crosses fingers)
Please star, but don't comment. There is enough useless comments there already, and everyone gets notified on new comments.

you probably have a rogue app killing your battery. if I let my nexus sit idle with LTE on I get close to 2 and a half days
Hi,
This high Android OS Keep awake time is not specifically about battery life issue.
We are discussing the fact that, because of this, the phone is constantly waking up (wake up state).
And that's should not happen while the device is turned off, for example.
Yes, of course, this will relate to battery life at the end. But, that's not the point of the discussion / bug as everybody has different preference of battery life. One can say 12 hours is enough, while others may say 24 hours is not enough, according their usage pattern.

This is nothing new. Android is a batt hog, plain and simple. You think google doesnt know this already. Its an "acceptable" item. Where they know about it & it's not the best, but thats what they get if they want a phone thats constantly using the network, has a large HD screen and is so damn good to look at you wont want to put it down.
Quit itchin and get on with it....
I have the extended battery from Verizon so keeping that in mind, my phone lasted 14 hours with 10% remaining with normal use. I stopped testing since I had to go to sleep
By the way I have Beweather and Facebook updating every hour and Pulse updating every 6 hours. I also have endgadget, Cnet, Google currents, Flickr and 500px updating.
So far battery life is a bit lower than I would like but not to a horrible state. definitely going to need the extended battery though. playing around today to see how fast I can kill it.
can't get photo to upload now though for some reason but got 2 hours 10 minutes with 12% remaining. would kinda like to see that as a stat added to phone reviews, minimum battery life. Max is fine but I'd rather know how long it will last with power using.

I'd say battery life was less than great on 4.0.1 but 4.0.2&.0.3 its pretty damn good now my idle usage is next to nothing. 2 days ago i had 47 minutes talk time, 1h38m screen on and about 13-15 hours of idle and still had almost 40% left at midnight.

I think you don't understand.
This is not about battery life, but the high Android OS Keep awake time. Which means your phone was awake when it's turned off.
Obviously, this doesn't happen on my HTC Desire, nor Nexus S with Gingerbread.

I can't speak for battery life on the LTE Nex as i have the HSPA+ version...I've found that the battery life is quite excellent after a few charge cycles...Have gotten 21hrs on a single charge with normal usage...if i'm watchin vids or playin games then im putting my phone on the charger cuz the screen really does eat up battery alot.
I feel like I make a thread for each phone I go through. First Blackberries, then Droid X, now Galaxy Nexus.
I am getting pretty horrible battery drain that is definitely worse than others' Nexuses. I have gone to the extended battery now for a few days, yet in the morning, when I unplug from charger (says 98% but charged?), with brightness only a quarter of the way up from lowest, I can literally watch the percentage (battery number mod in corner) drop one-by-one each minute or a few...So if I am actually using the phone, you can imagine it drops pretty fast. Yesterday, with very very moderate use the phone was still dead within 5-6 hours. It was at the mid-80s within an hour or more. Again, with moderate use.
It is stomach-dropping watching the percentage number just go down and down. Yet my friend's Gnex using the extended battery his first day did not hit 85% yesterday until 5+ hours later. The battery stats page on mine shows nothing with high numbers except Screen and Android OS, so I assume no apps are draining it. I am rooted with unlocked BL, on bigxie's deodexed ROM with softkeys mod, battery percentage mod, and power menu mod. I have 100-something apps and many widgets but no battery draining/updating ones. Others with the same ROM report fine battery.
I believe after using the ext. battery for a couple days, it should be "conditioned" if needed at all, yet I see no improvement.
I'm getting very angry watching this drop.. For example, 40 minutes off the charger with almost NO use except for turning the screen on here and there, I am at 94% battery with Screen at 46%, Android OS at 34%, Phone Idle 11%, Cell Standby 9%, and Android System 2%.
And then 1 hr 20 min in, at 88% battery with 55% Screen, 27% Android OS, 6% Phone Idle, 6% Cell Standby.
This doesn't sound normal right? Keep in mind, those numbers are with almost no phone use..very minimal settings menus visited and one update from Market.
Jesus, literally almost every time or two I turn the screen on just to check these numbers, I see the damn battery percentage drop a number. Not even using the phone how/as much as I normally would be. This is infuriating. Luckily, it doesn't seem to drain much with the screen off.
Quit checking and wait til the bug is fixed and blood pressure stabilizes?
Crazy world, ay?
Update to 4.0.2 or 4.0.3 with an improved kernel = success.
Use the phone for 1-2 weeks to stablize battery life - mine is better now than it was when I began using it. But the kernel/rom makes a big difference.
Thanks. Any suggestions on with combo to use now? 4.0.3 preferrably I guess.
Then why does my friend on totally stock 4.0.2, non-rooted have that great battery life from the first day using the extended battery?? I'm pretty much basing mine off of his and other's who are getting ridiculously long life. I never understood how it varies SO much. We should all have the same relative to usage.

No. Because no two phones are set up the same. Too many variables to say relatively same usage. For instance, when i go to bed i get 2-3 hours standby per percentage point. Not everybody is going to get that.

Maybe, but the fact that I have no other visible outstanding draining factors, and I get no 4G at home and therefore have it set to CDMA only...I should not be seeing 1% drops almost every time I turn the screen on for more than 30 seconds. Especially with an extended battery.
God forbid I want to use GPS or 4G.

You probably have a misbehaving app. Download better battery stats from the android apps and games section here at xda and let it run for a day or so and see what processes are being used the most and what your wakelocks are, etc.
Also, find a 4.0.3 rom with a kernel that can be undervolted and try that out.

Thank you, downloading now and will check it out.
I'll admit I'm using the GSM version so my experiences may not apply but for the first few days my battery life was utter crap.
Its been MUCH improved over the last few days, I dont have the wakelock issue and with the screen off the battery drain is literally only about 3% per hour, and thats with background data on.
YES, the screen DOES use a lot of battery, it isnt really avoidable and is somewhat expected with a 720p 4.6 inch super AMOLED screen.
The one thing I can recommend doing is finding a modded kernel and undervolting that CPU - It seems they've been really rather generous providing power to the thing, I've been able to take off at least 100-150mv across the board.

This - My battery on the stock battery on GSM sucked first few days, and I was really concerned I made a poor purchase. But with the screen on probably 5 or 6 hours of my work day it lives through the day and just enough to get home after that. I can charge it at work too, which I usually do. On my day off it survived 18 hours and still had ~20% battery life left on 4.0.3 AOKP/Francisco.Franco Kernel
From my experience, the battery life isn't bad. I did install the "extended" battery as soon as I bought the phone but is isn't much bigger than the stock battery. I am on stock rooted 4.02. With LTE off I use about 2% per hour in standby. With LTE on it is almost double that (3-4%/hour). I have several widgets running and gps enabled. (wifi when available) I can easily get a 16-18 hour day and have 50% remaining when I go to bed unles I sit around gaming for a couple hours.
I may try a new ROM tonight but I expect it will probably make things worse.
Im running a bone stock setup and im getting 12 -14 hours a day... normally I read posts like the one skiddingus posted and wonder why I never can achieve those readings so i feel your confusion . I do have 4g on and gps off screen is about 1/4 of the way up brightness wise
Hello ,
That's my first days impression about Xperia S !
any advice plz about improving the battery life please ?
Give it a weeks worth of charges to get going.
although screen brightness and 3G have the biggest impact on battery life

Thanks for your response , I will give it other chance and see what will happen
By the way screen brightness is nearly 40% and 3g is off
with every thing is off the battery may survive , but hello SONY GUYS , I didn't buy the phone to disable all it's abilities !

You might consider to check out some other threads before complaining about the battery life. There's many available so browse a bit i suggest.
Tips, Tweaks, and many other good information available on battery life extension. Search, you will find those.
And definitely the battery back up should increase after at least 7-10 days of use.
had the same impression when i first got my sxs, but after about a week or two, and a few tweaks it's pretty good now (1 1/2 day with normal use)
for the screen keep it between 40-60% brightness, especially if indoors. i only set it up to 100% when im outside at long periods of time,
switch off 3G/mobile data when you're not using it, and switch off "account sync" if you're not waiting for some important email etc. 3g/mobile data + account sync will kill your battery really really fast, so i advice refreshing apps manually.
i did some research and its fine to keep nfc open, since it uses very minimal battery WHEN it needs to use the battery which is pretty rare (unless you pass around a lot of data via nfc the whole day, which is pretty unlikely).
if you want to go the extra mile, unlock your bootloader, root your phone and mix and match with different custom roms / kernels that optimize battery life.
A very useful trick is to use 2g when you don't need 3g, it saves one hell of energy..
No idea what you're talking about. My battery goes for almost two days with 3G on all the time.
just use it for two weeks with normal charging. and if i were you, i wont unlock it until two weeks (but i have unlocked mine the first day i bought it..hahaha..),
why do i say this, so that if there are problems occur within those weeks, you can return it without problem.
and you will have more time reading and understanding anything that can be done with your phone,
see my signature "Read ME" for head start.
It's because you've just got it. Is it even updated to the latest software? And you've probably been dicking about with it non stop so of course you'll hammer the battery

Disable Auto Sync, apps like skype / viber are also hard on battery.
You may also try "Deep Sleep Battery Saver Pro" app.
Thanks for you all , I will try every advice written here
thanks again
