So I've had my Defy a week and I like it, more than I thought I would to be honest.
However, one thing that's bugging me is the battery life.
In their review, Engadget actually highlighted the battery life as one of the big plus-points of the Defy.
They state:
Engadget said:
In our experience, the Defy seems to have stellar battery life, which is relatively hard to come by among Android phones. Not only we were able to consistently make it comfortably through an entire day on a charge, but we were surprised to find that after putting the phone away with about 75 percent charge, it was still on with 21 percent remaining two days later. Granted, it spent most of that time in WiFi calling range (which disables the cellular radio), but many smartphones give up the ghost from 100 percent charge in less time...

Now, I'm not using wi-fi calling but I don't think that should excuse or explain the fact that my phone barely lasts a day when at least one other handset has such significantly better battery life.
Anyway, I was just wondering how everyone else's Defys were performing.
Im coming from a vibrant and the battery on this is the best on android so far that i've ever used(g1, mytouch, mytouch 4, vibrant, etc.

If you don't mind me asking though, how long do you go between charges?
As I said, I'm lucky if I make it much more than a day - certainly two days isn't possible.
But I'm not a particularly heavy user, a bit of internet and a few texts here and there but very little in the way of calls, so I kind of feel like I should be getting more out of the handset.
When I check the battery usage, it's quite often ~40% each for 'Mobile Standby' and 'Phone Idle'.
So the vast majority of the drain is just from the phone being on, not from anything I'm actively doing.
Is this your first smartphone? =)
I go a day and a half or so. I'm heavy on web use and playing 'slice it' all day.
for my usage, im THRILLED to have a phone that can still have 30-40% at the end of a long day.

Just try to reboot the phone after fully charged and detached from power. There is an issue with the "suspend" process in some cases (not only on Froyo 2.2) which disappears after rebooting. Mine lasts 2-3 days with average use.
The issue at Google (I am not allowed to post links as a new user )
code.google.com/p/android/issues/detail?id=11126
I can use the web steady for 5 hours, this includes some streaming video, if I start at 100% its down to 10% by then. At work it lasts easily all day but it gets little web usage and maybe an hour of talking. I use battery booster and advanced task killer, my backlight is set at 70%.
With moderate use (some calls, lots of texts, some web browsing) I get 2 days. It needs to be charged at the end of day 2, but I'm happy with it. I don't have any ot the social networking crap on so it's not constantly syncing. I think that may have something to do with it. I keep my backlight way down too.
Battery life? i got defy just a week ago and first impressions are good. You know, in the first days you make yuor phone working a lot, testing all the features, trying new apps from the market (so internet connection always on) , watching some movies, playing 3d games!
So a really heavy use, but power lasts at least 1,5 days. So i think using the phone moderately makes the battery life easily up to 3 days.
Try some task-killer app, and then test the power duration. Some softwares stay in background and keep draining power.

No.
And I don't see what that's got to do with anything.
My battery life seems to be noticeably poorer than what the majority of people here are quoting.
If I were to use the web for 5 hours, there's no way I'd have anywhere near 30-40% of my battery left.

Having looked at your link, it sounds as though when that's happening, people can see the Suspend process listed in the break-down of what's using the battery.
I've never seen it listed, so I'm not sure that's the problem here.

I've got Spare Parts installed and it's set to 'aggressively' monitor and kill processes.
A friend recommended it over the likes of Advanced Task Killer because it's supposed to be better at differentiating between apps that are safe to kill and parts of the core software/system that could cause issues if closed.
I get what you're saying about using the phone more than normal because it's new but in the 8 days since I got it, I've spent 7 at work, so I haven't had that much scope to mess around with it.
I've switched the screen from automatic brightness control and I've disabled the background syncing for facebook, so hopefully that'll make a difference.
If not, since it's just over a week, I'm well inside the 28 days I can have it swapped for being faulty.
Quadrant: 1100 points, Linpack: 6,49 Mflops
Edit: ooops, should read the title more carefully next time.
My defy runs for about 40 hours on one battery charge.
i have to charge mine everyday at night after using it whole day, time to time. Not bad tbh.
A task killer is NOT necessary.
It seems like blur services are push rather than pull which uses much less battery (think blackberry). But im not 100%.
I've set up yahoo, corporate, facebook, and picasa just to test it out and it didn't make much difference in my battery life.
I consistently get a day and a half (unless i play games). Can push to 2 days if i put on airplane mode overnight.

Found this on a german forum, as you can see, he was not in flight mode. I guess my desire's battery won't last that long.
I can go about one full day with moderate/somewhat heavy usage. Won't last 2 full days though.

People keep saying that but I'm not convinced.
I mean, if I use my browser say and then finish using it and know I won't need it again for a while, why prevent me from actually closing/killing it?
It seems so ridiculously counter-intuitive.
Plus, if it's really not necessary, then why are so many of them being developed?
Even Samsung are producing task managers now for devices like the Galaxy Tab - if it really wasn't necessary, surely one of Google's top hardware partners would know that.
And samsung is so great at making stuff...? Touchwiz??
Also, samsung's task killer does not show inactive or background apps like most task killers do.
What is the harm in the browser being open? It uses no cpu+ this phone has more than enough ram that it doesn't need you to close apps to keep things running smoothly.
It also will not improve your battery if you arbitrarily close an app only to re-open it later and use more processes.
Just my 2 cents on this topic.

Something i already posted in a german forum about my battery life:
2,5h gaming (Zenonia),
3h mobile internet (ICQ, Yahoo-mail, web, market)
2h of activated WLAN and deactivated sleep to copy stuff from pc to Defy
1,5h music (radio)
and 1h (and 6 minutes lol) of phone calls
After that day, i still had 30% of battery.
The maximum i reached were 75 hours including MY normal use with some mobile internet, some texting and 1 or 2 calls...maybe an hour of gaming at most.
I did not charge it first when i got it, because the battery was at 80% already/still and i wanted to play around.
Current running time: 26 hours...i activate plane-mode at night from now on. Low 70s now.
Everything at minimum display brightness (30%?)

In my opinion, a task killer is absolutely necessary.
All the apps launched keep consuming RAM even if they're not in use. I brought back 106 mb last time i performed a task killing! In most of the cases less ram means worst performances / more work for cpu.

I am currently using CM7 RC4 and have been reading through the CM forum for tips on how to improve my battery life. I must admit that I have tried various kernels (CFS and BFS as well as SBC and non) but nothing seems to really make a difference.
I average about 6 to 8 hours of battery life with light to moderate use. The most time I spend really using the phone is for the 2+ hours when I go to the gym and use Pandora. Besides that, I send some texts, browse the web and use Facebook. I know that there are a lot of variables when it comes to interpretation over how much use of a phone is "a lot" but still.........I hate how quickly my battery drains.
In one instance, I went to bed at 1 a.m. with 99% charge (having been off the charger only 30 minutes) and when I woke up at 8:30, I was already down to 57% with high Cell Standby as well as Android System.
I have now gone through and done the change on my phone to set the radio to "CDMA Only" as well as disabling Auto Sync.
I am currently using SavageZen Kernel CFS 0.2.1 and will report back on how it does overnight but.....definitely not holding my breath.
Any helpful tips are appreciated.

First, make sure you've done this: http://forum.xda-developers.com/showthread.php?t=712990
Also, turn off your back up data to Google servers in settings > privacy.
I've had it off for a good 5 hours or so and my battery life has already drastically improved.
To be honest dude, without an extended battery man that's about the best you're going to get. I consider myself a moderate-heavy user and I work from 8am-5pm. My battery is unplugged at 7am and when I get off at 5pm its on about 20% on my way home. I've tried just about EVERY rom(aosp/sense) along with EVERY kernel combination out there. I browse web, constant text, twitter, Facebook, email, maybe a game and I've never witnessed anything greater than what I posted above. No matter what people say to you about how great their battery life is or how its been running for 18hrs its all BS(w/ reg battery). Yeah if your phone is sleeping 90% of the time then yeah its believable, but for users like us 6-8 is about the best with a normal battery. Now a buddy of mine has the sprint extended battery; dude uses the hell out of his phone and can honestly say his phone last about 17 hours of power usage.
My tip would be to invest in an extended battery if you want more than 6-8 hrs.

Lol this is far from the truth. I avg 18-20 hrs with moderate use.

Define moderate use! My screen on my evo gets turned on like every 5 or 10 mins while wifi usage sits at 40% and the screen is constantly at 50%. My phone lasts me through work with pretty moderate/heavy usage(7-9 hrs) and I'm happy with my battery simply because it's not going to get better(regular batt). Now if your display never gets passed 20% then you're not using your phone buddy.But, if you're using a REGULAR battery and you're actually getting 18 hours feel free to post pics or no one cares to hear about this make believe 18 hours. Please do share how you actually use your phone; how are you achieving such great results cause as of right now you're just one of those randoms who come in and say **** like" durrrr I get 18hrs on my phone, but I post no pics to back it up". PICS OR IT DIDN'T HAPPEN

The best option I could suggest would be search E-bay for a 3500 MaH extended battery. They run about $.01 with about $9.99 shipping from China. If you need help I can send you a link to one of the auctions. Also make sure things like auto-brightness isn't enabled and that things are syncing a ridiculous amount of times per day. Good Luck.
Ive been running CM7 for a couple weeks battery life started going down hill fast.
My fix was to get new HTC battery for $7 on Ebay problem solved.
Just try turning the Google backup off.
I get from 10hrs to 15 but I turn off the day when I'm not using it and have my CPU set to run a at different speeds

Bro I bought a 3500+ battery from eBay and it lasts me about the whole day, this is with the exception with 3G on and heavy texting, moderate browsing and heavy and I mean "heavy" application use during the end of the day. On other days when I'm not texting I'm watching videos on youtube with the 4G on, this last for about 30 - 60 minutes top!. So whats my point? Say thing like you said, "My tip would be to invest in an extended battery if you want more than 6-8 hrs."

Im not sure what kernels are being used that are tossing out such ruff battery life but SavagedZen-1.0.0-CFS-HAVS-WiMAX-GB-noSBC is treating me right.
Simple performance setting in CM changing governor can get the job done adding many hours of extra battery life.

Smartass setting is great performer to say the least power packed battery saver.
Not sure if apps available but it would be nice if governor had timer settings were user could set what governor they want to run at what time automatically.
Example would be after 11pm power-save governor kicks in then returns to Smartass from 7am - 12pm etc.
If such apps available...maybe I'm missing setting in CM someone please let me know

Closest you're going to get to that is setcpu man. It does just about everything you just mentioned. There's a donate version in the market and a free version that the dev puts up for xda users try google search you'd find it in a heartbeat.
Actually I'm feeling nice. The latest version is 2.1.1.

Right on used app in the past but didn't get to deep into it.
Maybe CM will add feature stock simplifying it.

Actually I'd say its pretty simple enough in cm7 and I think it should probably stay that way to be user friendly to the not so savvy rooter lol. But above you stated you wanted more control of your kernel pretty much; setcpu gives you total control. You can set a diff governor profile for diff actions(plug, unplug, screen off), battery percentages, etc. I'd say give it a shot.

I LOVE the Galaxy Nexus, but the rate at which the battery discharges is just ridiculous. I'll use the phone for 15 minutes doing things like Twitter or Web Browsing, and it'll discharge 5% in that time. To me, that is horrible. I'm being really conservative too. Throughout a day I try not to play videos, games, or anything else intensive because I know it'll ruin my battery life. Even on standby it discharges 5% in an hour. Typically I lose about 10% an hour and my max has been 12 hours so far.
I have auto sync turned on and keep the screen low when possible. I NEED auto sync on because of the nature of my work. Compared to my iPhone 4S battery is downright pathetic.
Today my usage consisted of one phone call, a few text messages, lots of Twitter, and light web browsing. Nothing too crazy. Again I'm being really conservative with my usage whereas on my iPhone I can do whatever I want and not worry. I'm just not seeing how people are getting 15+ hours and claim heavy usage. I'd love to believe that! The battery drains so fast during normal usage it may be a deal breaker for me.

It sounds like your definition of light usage is wrong.
I wouldn't consider heaps of twitter and some web browsing light usage. I would consider it moderate usage, in which case you seem to be in line with everyone else.
I agree with you in that the battery life isn't quite what I would have liked. Ideally I wouldn't have to worry about battery at all, and I'd be able to play games and browse the web as much as I like, but for normal usage it's fine.
The next Nexus though, man, that will only have to be charged once a month. I can't wait.

Twitter hardly taxes the processors at all. Refreshing it every so often should hardly take any battery life at all. Web Browsing I can understand, but my total time browsing today probably amounts to 10 minutes total.
I wonder how much of the drain is attributed to the 4.65" screen. It's a monster.

I expect the battery life go improve within the first few cycles. I had a similar experience with the Nexus S last year.

Most of it. 720p Super AMOLED HD is killing the battery. The only way to last a long time is to not turn the screen on.

People using a G2x claim to get a day and a half... I'm lucky to get out of work. Push email for work is to blame I think. I get tons of emails (100 a day) and I think its taxing. From your pics, the screen used over 50% of it. That's a lot.
Sucks.
Also make sure your aren't turning on the screen every 5 minutes to check the status. Since your coming from an iOS, are you closing apps properly (back = close, home = minimize).
I'm not saying your crazy but just saying.

I had the same thing happen with the Nexus One. The battery wasn't that great but, got better after a few charge cycles.
I've never had a Android phone that could match the battery life of the Iphone. I can sit the iphone down at night without putting it on the charger and, if it's at 100% it will be at about 90-95% when I wake up. I did the same thing with my Mytouch 4G and, it was at 15%
To the OP, I would recommend keeping a charging cable with you when you out and about especially in your car. I've had car docks with a few of my android phones and, always keep the phone docked when I'm driving somewhere. It really helps.
What you also need to remember is this is the first release of ICS and is still in development so battery life my be improved in the next update. Like you mention iPhone4S there was massive battery leakage in the first release of IOS 5 which Apple apparently fixed in the newest update.. So maybe in the next update we can expect some bugs ironed out.
Used to only have ONLY 2-3 hours screen ON on my Vibrant so I know how SAmoled looks like.
I know iphone battery is good, but you need to consider the screen size too..
Get a spare battery with your "light usage", but I am thinking how much would it cost becoz of the NPC antenna.
Too good thing is, unlike iPhone, you can buy a spare battery and carry it with you.
3 hours of screen use is what the problem is. That is a long time. I wouldn't complain about that at all.

I already said I didn't play any games today and my screen brightness is low. For some reason Shadowgun stays in the battery info screen. I played the game two days ago and manually closed it out. Even after rebooting the phone its still there.
I'm being 100% real, stop trying to make excuses or act like I'm an iPhone fanboy. The Galaxy Nexus combined with ICS is the best phone I've ever used! I'm just terribly disappointed with the battery life.
Twittering all day is sucking up battery because of all the data use. Dude, youre not a light user with 3 hours screen time moderate, possibly heavy depending on background stuff sycing automatically. You have some tweaking to do, not whining.

3 hours is not that much. Seriously. It shouldn't be damn near dead after 10 hours. Imagine if I decided to play a game for 15 minutes or watch 2 YouTube videos.
I bet if people were getting an hour and half with this phone, all the fanboys here would say the same thing. "Man, an hour and a half is a long time! You should be happy with that!".

I've tested out the battery difference by turning off auto sync. Doesn't make a difference at all. Fact of the matter is that the battery drains like crazy when the screen is on.
I'll just turn my phone on because actually using it is frowned upon here.

Except they aren't out yet
Hey guys, so i've noticed that a lot of people are complaining about their battery lives. There are a few things that I have done which are not too complicated that I think the rest of you should do too (if you haven't done so already). With these steps, i have my brightness almost to the max the entire time, and the battery lasts me most of the day without needing to charge.
1) Calibrate your battery - This first step is a given, and should definitely be done, especially after rooting. You can find steps by searching in the forums for how to calibrate battery.
2) Uncheck "Use Wireless Networks" in the Locations menu in the settings. This is a huge battery hog, if not the biggest on the phone (next to brightness and 4G). If you feel like you need it to use the "Places" app better, then you can either always turn on GPS just when you need to use it, or just search for whatever you want in Google Maps directly. Many ways around this problem.
3) ROOTED USERS ONLY - Get a root explorer, go into /system/apps and move the following apps to a different folder, preferably on the sd card: Socialhub.apk, Mediahub.apk, Sprintzone.apk, SprintID.apk (sometimes called w_sprint.apk). Obviously if you use those apps, dont move them because you'll essentially be deleting them, but from my experience most people don't use them, and they are always just running in the background. Huge battery hogs as well.
- You can also delete the other sprint apps through the usual app removal process if you'd like.
Also, if you use widgets such as Beautiful Widgets, or Minimalistic Text, for time and weather that require Use Wireless Networks for updates, it would be best not to use them. Especially BW, drains a good portion of the battery. There are other alternatives that I feel are just as good, such as a decent looking modded stock digital clock and the genie widget from ICS (Thats what i personally use). They take a fraction of the others and provide the same information.
Very nice tips. I didn't really like media hub and got tired of seeing it.. but the sprint files you mentioned weren't in my folder.. The apps are still there
EDIT.. also can you like me to battery calibration instructions? O didn't even know that was a thing...

You can also freeze those apps if you are rooted. Same results
How do I go about doing that?

I am always so surprised to read people with bad battery life. I have a stick phone running all sick items except having root and I well easily get well over a full day on my battery. I plug it in asst the end of the day with 60% battery on a regular and that is after 14-16 hours. GPS always on, brightness on auto, sync what needs to be synced, using the phone as a phone, with Bluetooth at times as well. The only time I lose significant power is when I use Netflix or start running games for an hour or so.
Are people running stock on this or a built ROM? Also, are you running stock kernel with CWM? CWM put my battery into a hole so I went back to stock without CWM, no idea why out would do it though.
Examples of battery life.

It seems to me like from those pictures that you barely use your phone for other things than making calls. The reason that i can come to that conclusion is because your display battery usage is just so much less than your Android OS, that just means your screen is off for the majority of the day. I'm assuming from that that you're probably an older gentleman who has less use for things like texting and Facebook. Unfortunately, the majority of my communication is through those 2, as well as some other channels.
And to answer your other question, i am running stock rooted without cwm.

I guess i can just describe it for you, its pretty simple. Just follow the following steps:
1) charge your phone to 100% (if it reaches 100 unplug it then plug it back in, it'll most likely take another 20 minutes to truly reach 100)
2) if you are rooted and have clockwork mod recovery, boot into recovery, and wipe the battery stats. Then continue to the next step. If you are not rooted, dont worry, just go onto the following step anyway.
3) from the market, download a battery calibration app and calibrate it.
4) then use your phone regularly throughout the entirety of its battery cycle (don't plug it in for mini charges until it fully dies)
5) when it dies, recharge it back to a full 100% (don't unplug it before it reaches 100%).
Then you're done.

I wouldn't jump to that conclusion. By the end of a 16-hour day, I have about 2-hours of screen-time, and my battery is around 50%. I have corporate email on my phone, so it wakes up frequently, and I check my messages all day long.
There's also the issue with Android OS taking up way more of the battery charts than it's supposed to. Most of the time, that bar is 2x longer than my display bar, unless I unplug it and play a game for four or five hours. There is a bug on this phone, that either calculates the Android OS bar improperly, or the phone is genuinely using tons of battery in the background and Android OS is a giant battery drain.
If you hang out on the forums a bit longer, you'll see this pop up pretty often.

lol, I've actually already read those forums before, but the thing is that I just don't think its a bug with those people. The thing is that its simply a balance. If your screen is set to a very low brightness, or just off most of the day, it clearly won't be the main battery drainer, but all that means is that something else will be. Something will always be the main battery drainer, even if its not draining that much.
Maybe it just makes more sense in my head than on here, but I'm pretty sure lol.

That's even better with showing you all his awake time. You are right, I have never wasted my time with Facebook, the internet can live on without my updates, but I do use the phone for corporate email all day as I work remotely and I am on the phone regularly for work. Not sure why you would be getting such bad battery life. I was just trying to help and see if there was anything you could pick up from me that would help with you.

It is in fact a bug. Here is a bug report in Google's bug tracker. Here's another. There's also a very long XDA thread that explains what the Android OS bug actually is, and how it works.
If the lines are proportional, then Android OS is using more power than 2 hours of display time, and I've gone as high as 5 hours and 30 minutes. I've had times when 4 hours of screen time is still less than Android OS. What? That makes no sense.
From the XDA thread:
Same network, same location, same signal strength, same ROM (Changing my font maybe fixed it....) , same wakelocks between them, same background apps running. Not even 5 minutes screen time on the two. The only difference with .14 patched kernels I'm experiencing is that it's not showing up anymore in the stats, but it drains just as much as in the right screen, showing the same CPU state behavior. It's also happening less often, and many say it's not happening at all anymore, but how would they know it it's hidden now?
Click to expand...
Click to collapse
Before that were two screenshots. One of them showed a minimal Android OS bar, while the other had it at 95%. The only difference was the patched kernel. This. Is. A. Bug. Period. High Android OS usage means absolutely nothing. Even after tracking down wakelocks, it will be high or low pretty much at random. Sometimes this is a legit stuck suspend, in which case rebooting is the only fix. Other times, it's just the bad profile. There's no way to know unless you study CPU spy, better battery stats, and possibly Watchdog.
In any case, read that XDA thread that explains what Android OS is. It has very little to do with how much screen time you have.

wow, thats crazy.
I'm not trying to bash you or say I get bad battery life. I just don't see someone who is taking his or her phone out every 10mins getting emails, and calls, social updates, background syncing is going to get 10hours of battery with just about 95% left.
Maybe if all you do is check emails and take 15 min calls and put your phone back into sleep mode you can probly get that. But even then. I can't say real world usage = 10hr with 95% left. only if you have a extended battery on
From my Samsung GS2 E4GT
This is with an hour of screen time. Admittedly, that's less than half my normal usage, but I was working on my book on the train instead of reading reddit. I'd normally be in the 50's by now with about 2.5 hours of screen time.
Way better than my Eris.

i've found that turning off facebook and twitter sync alone have greatly improved battery life. enough where i dont really have to diable anything else.
i get 24hrs without a charge no problem now. using a rom based off calkulin's EK02 rom.
*this is the 3G version
hi guys, first time posting here. Did the search, wasn't quite satisfied with the search results though, especially now that i have some graphs to show, I hope you guys can help me answer my questions more specifically.
I'm also a first time smartphone user, so please don't be too harsh on me
see, i can see how smartphones have worse battery lives with the fancy screens, fast processors and such you know, but this :

is why I decided to spend some time to make these photos and have you pros take a look at them.
That was from waking up from sleep, then playing about 3 hours of texas poker.
I didn't like that chart, and I hope you understand why.
As I said I'm a first time smartphone user, and I've been telling myself not to get TOO picky on things, but this is.....well.....let's just say not very satisfactory.
So I did some tests on how my phone does in different levels of usage.
Trial 1 : Light usage
let's say within the 19.7 hours, its around 9 hours of sleep, 7 hours of occasionally checking for notifications, 1.5 hours(most of that screen time) for whatsapp and games with light web browsing
I get 2 hours before it dies. It might not look bad because I slept during that period, but hey, what if I didn't? That extra battery used in standby mode could easily be used up in 10 mins of screen time, so its still 2hours 10mins only.
Trial 2 : Light - medium usage
No sleep in between this time, about the same amount of usage except I browsed web for a bit more it seems. This is likely the situation of a full day of work. (NOT COUNTING the transportation periods)
This seems to prove my judgement on trial 1.
Trial 3 : Extreme usage
This one is easy. Basically just leave screen on the whole time and do something with the phone during most of that time, I actually wrote down what I did with it.
- 40mins of 720p youtube videos
- 1~1.5 hrs of whatsapp
- 10~15 mins of texas poker
- 20~25 mins of words with friends
the above add up to be 2.5~3hrs, remaining screen time is from random scrolling through homescreens
Result is almost the same as the first pic shown on this thread.
Useful info :
The calling time during these test trials are insignificant to none
Version : pure ICS restored to factory settings, no additional tweaks
Brightness : Auto
Screen-on time before standby : 1 minute
Sync : both number and google mail account
Location services : I ticked the first one, letting apps track my location, and none of the other 2
I have about 5 apps and 10 games on the phone, no widgets are being used on homescreens.
So finally my questions are :
1) is this kind of battery life normal at all? (keep in mind that I'm using 3G version, none of that LTE battery killer crap)
2) what settings can I turn off to save some power? (the sync options? what are the negatives of turning those off?)
3) I read in some of my search results that there's a file related to battery stats and if I kill it I might get better battery life out of the phone? (or are there other similar tweaks I can do on the file-manipulation level?)
4) efficient way / app to help save battery without rooting? Read about a few on this site already, but it always seem like you guys still have debates on whether they are effective or not
Thanks for reading and thanks for helping!!
Hey, I fell asleep reading all this! Joke
I was disgusted with my battery when I first got my nexus and although this is not a solution of any kind I just think unless you are prepared to root and use modified kernels you are wasting your time trying to save battery with the stock ones.
I use an apex kernel now along with some power saving features like turning off data and wifi when I turn my screen off (AOKP) rom. I use quick profiles to change my screen brightness as well and my battery performs pretty well.
Anyway just thought I would share. I hope whatever you do you get sorted but do consider rooting!
So finally my questions are :
1) is this kind of battery life normal at all? (keep in mind that I'm using 3G version, none of that LTE battery killer crap)
Your battery life does not look that bad for a smartphone profile. Your screen is going to kill the most battery with LTE being turned off
2) what settings can I turn off to save some power? (the sync options? what are the negatives of turning those off?)
turn off bluetooth/GPS if not using. Use WIFI for DATA as that uses less battery then 3G. Turn down screen brightness. turn off syncing on facebook/twitter/social apps/google reader. you can manually sync them when you enter the apps. Also disable syncing on stock weather/news app.
3) I read in some of my search results that there's a file related to battery stats and if I kill it I might get better battery life out of the phone? (or are there other similar tweaks I can do on the file-manipulation level?)
You dont need to reset the battery stats to get better battery life. those posts have to do with repeated ROM flashing
4) efficient way / app to help save battery without rooting? Read about a few on this site already, but it always seem like you guys still have debates on whether they are effective or not
Without rooting, the saving battery methods above are your best bet.

You will get around three hours of screen on time from your battery on 3G. Almost always. To the person who said use modified kernels always, that's not true. The stock 4.0.3 kernel gives excellent battery life for the GSM version.
The battery stats file makes a really negligible difference.
Sent from my Galaxy Nexus using xda premium
your battery is basically normal. there's not much else you can do really, we all get about the same screen time and standby time.
thank you all 3 of you
from your replies, I take it that this is actually normal?
well that sure is.....surprising.....negatively......lol
I mean, I'm fine with the extreme usage part, if im really looking at it for 4 hours straight even I get tired myself, but by dragging the battery to 9 hours, which is essentially just a bit more double of 4 hours, I only get bit more than half of the screen time(2 hours) ?
I'm sorry but its just hard not to feel disappointed, switching from a nokia, and not the good ol' bricks too, that little guy got a 2.8" or 3" screen, color was great on that thing and it can play 4-6 hrs of music and still manage 1.5-2 full days.
Judging from what you guys said, it seems like my best bet is actually an extended battery.....
Also, reason I didn't want to root the phone is because....well, isn't the "pure ICS" one of the major selling point of the nexus? what's the point of buying it if I root it? Might as well went for the SGS II?
I actually waited 2 full months for the release of this phone since I made the decision of a phone switch. It was such a tough wait, everyday went by with me knowing that I was probably waiting for a phone inferior to the SGS II, at least hardware wise.
that said, i might try rooting later on, maybe half a year later once I'm more familiar with android execution. I'm still learning most of the stuff, and my homescreens make my phone looks like the I_____ 4 with nothing but app icons
The battery life is Godly on the Galaxy Nexus (Mine's a GSM model...I have no clue about the CDMA version)
With around 10 calls made, my brightness using the power control widget at "half" (I think its something like 40%), wifi on all day, data on, bluetooth&GPS off, NFC off, and almost 2 hours of onscreen time spent texting, surfing the web and gaming I got almost 22 hours on battery with 46% remaining!

For those interested in getting this type of performance, I have sync OFF and manually sync whenever I want to check something (mail, weather widget, etc)
I have not had a phone with this great of battery since the Xperia Ray. This is unbelieveable though.
Also for those interested this is what I am running for ROM:
Android version: 4.0.3
Kernel Version: 3.0.18-imoseyon-1.9.0-04417-gcef4285 [email protected] #408

Now how should I kill off my remaining 46%? Because web browsing, playing Nintendo 64 games, Facebook, are not cutting it! LMAO

Its not really limiting it though.
If I want to see the weather, I touch the widget to sync. If I want to see if I got any mail, I go into the app and it will sync...I get my data when I choose to.
I don't own anything to hook up via blue tooth, and I will just turn GPS on when I check google maps, takes an extra 3 seconds.
I am not missing out on anything, I am literally getting 2 days between charges. But I charge every night anyways, so I can basically surf the web or do whatever on the device all day and still have a ton of juice at the end of the day.
hey man, if thats how u use your phone, then u have great battery life! everyone's uses are different! people can say "oh your bluetooth isnt on" but not everyone uses bluetooth, or needs their auto sync on, etc! some people like to check these things manually
you should update your kernel to 1.10, reports have said that it brings back battery of 1.7.4 but also ups the overall speed/smoothness of the phone

Yeah I mostly just call, text, websurf, and game. So it works for me.
In comparison, using my Xperia x10, Samsung Captivate, Desire Z, Desire S, Xperia Arc, Nexus S, and Xperia Ray I never got battery life like this. The Ray was close, but this is even better...considering the size of the screen this is really great in my opinion.
I just love this device so much, I am thinking I will just always stick to the Nexus line of devices for now on.

Look, Samsung has NO way to give standby times when everyone uses their phone differently. I sync differently from you. This phone WILL get six days standby. My old Vibrant is rated at 16 days standby, and you know, it just about will get that. "Standby" times aren't "my screen is off". Standby times are no data/wifi/sync and my screen is off. My mother has my unlocked Vibrant on AT&T. She doesn't have a data plan. Data/Sync is off. It's used as a PHONE. After her normal use, which is about 10 minutes of talking a day, it'll be at around 40% after 6 days. At that point, she usually charges it... and that's with evil, battery draining TouchWiz! There is no way for a manufacturer to adequately predict standby times with a device connected to a data network.
Honestly, for the life of me I can't figure out why this is an amazingly hard concept for people to grasp. Just because it's a "smart phone" doesn't mean that manufacturer's test battery life with data/wifi on. Probably because unlike the majority of people in every random battery thread on the internet, manufacturer's realize that once a data network comes into play, usage/sync WILL be different. Even power consumption can vary from tower to tower.

Perhaps you're giving Samsung too much credit. Apple lists the details of their battery tests on their site, and when they say "10 hours of use", it's not piddling around with sync off, location off, etc. it's actual use (calls, web browsing, video, music).
Look at gsmarenas battery tests http://blog.gsmarena.com/samsung-galaxy-nexus-battery-life-fully-tested-results-come-out-disappointing-test/.. Galaxy Nexus is tied for second worst and all phones were tested the same way. Maybe "real world" use will affect a single device from day to day, but when a phone is compared to close to twenty other phones under the same conditions, it makes you realize how poor the battery life is. Maybe 4.0.5 will make things better... I hope so.
Sorry for a newbie question.
I've had Auto Sync ON all day and I wonder what Auto Sync does exactly ?
Can someone light my day ? Thanks
