Yet, another battery life thread? - Samsung Galaxy Nexus

Hello,
I know all of you have heard this time and time again. I'm sure I'm going to create a huge battle discussion, which I don't want honestly. But I've searched throughout the forums with no luck, and if I've missed this, please direct me and delete the post. So, with that said, hear me out..
I understand apples iPhone's battery tends to last long because of the not so true multitasking, and there are hundreds of ways to make androids battery life significant.
I was just wondering if there was any ROM, kernel, etc to get rid of the "android true multitasking" to increase battery life. Myself as an android user, never tend to use widgets or really have any use for multitasking anyways. I play on facebook, text, and make calls periodically. Anyone want to chime in without blowing my head off on this one?

ICS and JB both have an option under settings/developer options called Background process limit.

Did not know that. Thank you.
Does this increase battery life, that you know of?

Really? Doesn't seem like it would or even that it would increase battery usage since apps have to be restarted every time.
It will definitely free up ram, but that's not really an issue with the GNex.

I should probably also state that I'm on Vicious CM10 w/ stock kernel, and have not yet seen more then 10 hours and 2 hours on screen time.

For my opinion I think depend on lifestyle you use phone

True, but I only use my phone for browsing facebook, xda, and text messaging. I never play games, use youtube, netflix, or any other battery drainer. I also keep 4g off. I would think I could get more then 10 hours and 2 hour screen time with the 2100 mah extended battery (already exchanged for a new, so it's not the battery)

I've been doubting myself too much

to the point where I'm thinking of returning my Galaxy Nexus. The phone is beautiful and slick but I can't deal with the battery life. I'm especially worried for when I go back to my University next week because I'm not sure if the phone would last while I'm going from class to class from 9 AM to 5 PM everyday and most rooms having low to no reception.
Before this phone I had the HTC Thunderbolt with the extended battery and it could last me the whole day while I was going from class to class and under heavy and constan usage (to the point where I never had to bother monitering it or caring about the battery). I would have auto-brightness on, GPS, Google Latitude, use Facebook app freeling, have Google+ uploading my pics as soon as they were taken, use Pulse, and be ALWAYS connected to 4G without worrying about the battery life.
Now with the Galaxy Nexus I'm forced to turn down my brightness, turn off GPS, turn off Latitude (you can see where this is going. Pretty much opposite of Thunderbolt), uninstall Facebook and disable Google+, minimize my usage, and use Wifi whenever possible to get through a few hours. I even uninstalled Google Voice today to see if that makes any difference. Really? Why am I crippling my smartphone? Why should I have to turn off 4G on a 4G phone to save battery?
I'm obviously an idiot for comparing a Thunderbolt that has an extended battery (2,750 mAh) with the Galaxy Nexus that has a normal battery (1,850 mAh). It's also my fault for trying to believe that battery technology would improve in about a year especially after the horrible battery life from the Thunderbolt; I thought that people would learn from other's mistakes. I thought that the Galaxy Nexus, Google's new and precious baby, would fix the woes from previous phones.
I've been following a ton of forums to find out if there's a fix and I've done a bunch of stuff (disable Google+, uninstall Facebook, etc) but there's barely a difference. Some people are suggesting that an update will come along to fix the battery but I'm tired of hearing that excuse. A software fix will only do so much. And 4.0.3 has been announced for a quite a while from Google. Why hasn't this phone been update to 4.0.3? Why did Google halt it from the Nexus S? Is there something that's running down the battery even more with that update? I don't want to go off topic but I just hate being kept in the dark and not understanding what is going on.
Here I am now typing this as I'm looking at my Thunderbolt while it charges. I'm planning on trying out a few ICS ROMs to see how they go. I'm just tired of second guessing myself. The Galaxy Nexus is a beautiful device, both software and hardware wise; the camera may not be the best but I love it's speed and ICS is just sleek as F. But I can't fully enjoy the phone with the mediocre battery life that I am getting.
I suggest stock 4.0.2 with ogdobber's jamesbond kernel which only has undervolt open and the gpu oc'ed. Probably need to turn off lte and stick to the CDMA. 3g CDMA isn't fast but it is passable and battery efficient.

even if battery tech does drastically increase 1750 mah will ALWAYS still be 1750mah it may take up less space or create less heat.. Mah is a measurement of milliamperes per hour
Try Paul O'Brien's excellent MoDaCo ROM - very impressive battery life and for $9 you get access to the kitchen. There's an update due today which will fix a flaky call issue.
Alternatively, hang on for 4.0.3 which is likely to bring some decent battery life improvements and bug fixes (though wouldn't surprise me if it's out for the Galaxy S2 first). I used to get 2-3 days of heavy use from my SGS2, get one of those and wait for ICS if you want better battery.
And a last alternatively... shove one of these in your bag:

If your in places with no reception, put the thing in airplace mode or disable mobile data.
This phone gives me the best battery life vs my last 4 phones,... HTC hero, htc evo, Nexus s, and htc evo 3d...
Get an external battery. Since you are in uni I suppose you will be carrying around a bag anyway so it won't be too inconvenient to lug around. Just leave your phone charging during lunch and it should last the rest if the afternoon.

Go into your sstem/app folder and take off apps that you don't use. EVERYTHING you don't use. if you take a trip to that folder you're gonna see a lot of **** that you didn't know was there.
Do some cleaning and you should be fine with your normal usage. Also, try to flash a kernel so you can customize the governors and allow the phone to sleep more efficiently.
Coming from a thunderbolt, you should know how horrible battery life is for ANY stock android device...
There's no need to gimp your smartphone. I fluffing hate it when people say "just disable 4g, 3g, take auto-sync off, turn brightness all the way down, and only surf the web with wifi"
WHAT? WHY THE **** DID I BUY A 4G SMARTPHONE THEN IF I'M ONLY GONNA USE IT AS JUST A PHONE?

Also to put it in context...I'm using the epic 4g and I still have the stock 1500 mAh battery and the only time I lasted more than 4 hours on stock without having to charge was with a gngerbread leak.
But after a couple days of devs getting dirty and taking the time to clean up, your battery should last exponentially longer since people will have figured out what exactly drains the batter and how to stop it.
On the epic, it was the DRM. **** always ran in the background, then someone discovered it and about a month later it became so irrelevant since all the devs knew what code to get the drm to stfu until you needed it

Lol lay off the nerd 'roids. It like leaving all the lights on and air conditioning in your house and wondering why the bill is so high. It's like a lot of people are expecting their smartphone to automatically be efficient. Get a bigger gas tank if you need to run a marathon. Otherwise sprint efficiently with what you have.

Battery lasts me all day on the GSM version.
Folks, powering an extra radio uses extra power.
Moreover, the longer your data connection stays active, the longer your radio is active which is an even bigger drain. Since the LTE Gnexus devices are powering 2 radios (CDMA *and* LTE) simultaneously, and the second radio isn't as efficient as the standard radio that's part of the SoC package, this means that you need to ration your data usage if you want your battery to last.
Again, on the GSM version this isn't an issue because the radio is built into the SoC from the ground up, as well as it being only a single active radio at a time (GSM *or* UMTS/HSPA).
Software updates won't change that. It's a matter of physics. The LTE version may see some improvements here and there, but no software will counteract the effects of having to power 2 radios constantly.

Lol its definitely not like that. Its more like buying a new eco lightbulb that you use just like your old lightbulb but your bill is $80 more. Wut? LOL
But nah my epic 4g lasts me the whole day with 4g on (no access to wifi :[ ), auto-sync for gmail (i don't use facebook so its always the first app to go), blah blah blah. The only time battery is a problem is if I'm in a no sprint zone and forget to make my phone roam. Other than that, its used as a smartphone with 3+ hours of screen on time (voodoo color allowsyou to edit the gamm values and what not so its able to sip less power for the same brightness if that makes sense)
Seriously, root your phone and if stock is your thing, just install a custom kernel. Kernels handle the voltages and frequencies andhow your phone interacts with certain things so a custom kernel will almost ALWAYS have been optimized over stock. You will probably see a muc better result if you flash a ROM and Kernel, simply because custom roms are made to work without all the extra **** running in the background that no one wants

Just to clarify, make sure you KNOW what you're deleting and make backups anyway, just in case something you remove from there causes issues with another application that expects it to be there. Sure, you can remove a lot (if not most) of things from system/app without harm, but don't just go deleting random things unless you are SURE there will not be side effects.

You can have good battery life, of course
Here is mine, all stocks, not-rooted, not-unlocked, 4.0.1, yakju.
Using EXTENDED Battery 2000 mAH, GSM version.
Stand by 2 days and 7 hours, screen on time was 3 hours and 18 minutes.
It still has about 17% battery life, which could easily translate to 1 hour or so screen on time

Your words were to delete EVERYTHING in system/app that you don't use. I'm not trying to pick an argument here, but I just like to clarify, because what may be common sense to some people may not be to another. Not even necessarily the OP, but others that come across the thread in the future.

Best Kernal for Battery life on Extended Battery

So just got my Galaxy Nexus on Verizon and already unlocked running stock 4.0.4 rooted. I got the extended battery (2100) and I am still kind of disappointed in battery life. I mean, even on 3G all day yesterday it lasted maybe 9 hrs. I have turned off a lot of background apps but still hasn't helped much.
Any suggestions on good rom's/kernels for the best battery life without having to sacrifice too much on the performance side?
Figure it out man.
Everyone (literally) is going to say something different here.
I'll vote Immoseon's 2.3.0 stable with stock clocks but dropped the vsels down by 100 personally.
Next guy will vote franco's.
Next guy will say popcorn.
^This man speaks the truth.
The problem with statements like "X kernal is best for all situations" is that it CANNOT be true. Kernal's will give you varying battery life depending on what you use them for. Since only you know what you do with your phone, you'll have to do some trial and error to figure out which one works best for you.
I, for example, browse fb, read some ebooks, and browse the internet randomly, I've found Franco's Kernal works best for me.
Perhaps a heavy gamer may be that to be untrue. Perhaps someone who takes lots of video/photos do not agree. But for my purposes, I am satisfied.
GL!
If the next vote is for popcorn I'll feel like a wizard

Lol yeah, another one of the "best kernel for blah blah" collection...
Adding my agreement to try them out and see. I like imoysen, but that is based on my usage.
One thing I will recommend is fully charge your phone before installing a new kernel, then wipe your dalvick and battery stats after installing. Then let it drain till it dies and fully recharge it in one go. Then evaluate your battery performance. It will give you a more accurate view of how it will perform. giving your phone a few days to settle into a kernel always helps, imo.

Hi. Can you give us some definite figures and how much better battery life you're getting (percentage or hours). I'm a new gnex owner and although I will definitely root my gnex eventually, I'm currently reading through all the threads regarding battery life.
I'm a moderate user myself - using it mostly as an e-reader with the occassional gaming, browsing, call and text. Right now I'm getting the following performance:
15% remaining at 13 hrs
4 to 4.5 hours display time
Like most users, my main concern when I root will be battery life.
Wiping battery stats does not improve battery life.

Terrible battery life
I'm not completely sure why but for me it has been terrible. Drains to less than 40% in 5-6 hours. I at first thought it was the overclocking I did, then I set the max CPU speed to 1024 MB and it's still terrible battery life. I have wi-fi and data off most of the time and the phone not being used and it still drains this bad. Can someone help me? I've tried a few different governors under the CM9 settings now, which is best? I notice that wi-fi and the screen are using the most power. Why does wi-fi remain on/drain power even when the screen is off? Sense managed to save my battery and make it last for like 2 days (as mentioned in the OP) by turning off wi-fi and data when the phone was asleep/locked. Also, I used auto-brightness on Sense and got the 2 day battery life. Auto-brightness on CM9 seems to be KILLING my battery.
Someone help me get max battery life out of CM9 for my HTC One V (CDMA) please!

Actually I had other reasons to wait including concerns about my first flash.
I did end up flashing last night, but not based on the in-depth experience your 1-line reply to this thread described. I actually had any questions I had answered on the IRC channel by a few devs which was highly appreciated.
I don't think there is anything wrong with people waiting for even more stable versions and commenting on that as such. Maybe instead of trying to provoke me through insults you could have tried to convince me. Otherwise your criticism is useless without any sort of construct so please keep it to yourself.

Exactly what app did I say was sucking my battery? Oh right, I didn't. I asked for help on how to get max battery life with CM9 (like how I should tune the settings) and of course I get someone who thinks they know everything coming in here just to talk **** on someone else. Why did you even bother to post dude? You just wanna call people out and put them down. Does that make you feel better? Insulting people via text on an internet forum? Real cool man... Who's the real mr. perfect here?
That being said...
The ONE AND ONLY issue I have with CM9 is that it seems to be draining battery way too quickly. The first 2 posts claim to get the same battery life as with stock rom (about 2 days). Can someone (someone who actually wants to help here, not someone who just wants to laugh at people who don't have EVERYTHING figured out and perfect like they do) please tell me how they have set up CM9 to get 2 days battery life. I really really like CM9 and the only thing keeping me from using it is this battery drain.

Well, I use JuiceDefender to switch off wifi and 3G when the screen is off. Also, I don't use autobrightness, opting instead to set screen brightness to 20-30% (which is still pretty bright IMO). Been getting 1 and a half days out of the battery with low-mid usage (texting/calling/checking Facebook & Twitter)
However, I've only been using CM9 for about 5 days, so you might want to take my advice with a pinch of salt. Hope this helps anyway.

[Q] What are you currently doing to increase battery life?

We all know our GS2 runs out of Battery at a faster rate than what we would like! I'm just curious, what steps do You take to increase battery life, if any.
-Do you use certain apps?
-Do you enable/disable certain things and certain times?
-Anything, ever the smallest things you do, I would like to know!
I'm just curious to see what different people do to strengthen their battery.
(Also, if you could, please just post what ROM you're running on too) Thanks!
I use developer options and limit the apps to 4. I also under clock to 200. Stock rom.

Battery Life
Im running FK23 leaked rooted with stock kernel. I use powersave mode that comes in stock settings app.
I don't limit cpu. I use phone to txt, play games, youtube, facebook, twitter, and instagram and google play store.
I get around 14+ hours usage.
Also, I try to use WIFI whenever I can. I turn off GPS when not needed. I dont use 4G often as 3G is pretty good on FK23.
Lasts me from 7:45AM to 10:27PM as of now on 1%.
Wow, and how much do you use you're phone throughout the day? I'm just looking for new ideas because I do several things to increase my battery length, but I find myself around 50% in the first 2-3 hours of my 11 hour day. :/

I bought a cheap ($10) extended battery and cover, and a cheap ($9) TPU case/ At 14 hours, I still had 61% battery left. I can get a full legitimate day out of it running 2.3's, but I am going to try JB and ICS again and see where it's at.
I run KingKang with the JB tweaks package. I also modified my build.prop for both performance and battery life. Plus I toggle my 3G on only when I need it. If I have a WiFi signal I'll do the same with that. I average 17 hours but sometimes I get more than 24. Inverted apps not only look great, but help with battery too.

Honestly? #1 thing I do is stay on wi-fi as much as possible. Have gone almost 24 hours if I keep off 3G/4G and moderately use the phone/'net.
Where did you purchase the battery, and how much stronger is it? Also, what kind of case did you get, one that chargers your phone?

Just bought the cheapest 3500 mah battery with a back plate on Amazon, then the ONLY extended tpu case made by trexcell on Ebay. 20 bucks and I leave wifi gps and everything I use on all day long.
Epic4GT with different ROMs every few days. Thanks Devs!

We all know our GS2 runs out of Battery at a faster rate than what we would like! I'm just curious, what steps do You take to increase battery life, if any.
-Do you use certain apps?
-Do you enable/disable certain things and certain times?
-Anything, ever the smallest things you do, I would like to know!
I'm just curious to see what different people do to strengthen their battery.
(Also, if you could, please just post what ROM you're running on too) Thanks!

I switched back to Calkulin 3.0. Battery issues solved.
I tried to make ICS work for a couple months, but grew to hate the phone. It's a much better phone when it runs Gingerbread.

I did the same as you until the fk23 leak came out. Calkulin's v3.0 gb is amazing for battery life, smoothness, and functionality. I was never fully satisfied with any of the ics solutions, stock or custom.
Although the fk23 battery life isnt as good as calkulin, I'm still using it as my daily driver bc it's jellybean and cool, the phone runs well and smooth, and battery is good enough for me.
To answer the op's question, I do the following to help extend my battery life:
1. Leave off all data unless I need to use it (3g, 4g, wifi).
2. Turn of autosync and only sync as needed.
3. Remove bloatware and/or freeze any unnecessary apps (use GSM battery and OS monitor to find battery hog apps).
4. Leave off GPS unless needed.
5. Set screen brightness lower.
Here's a link to my FK23 results over in the battery thread in General:
http://forum.xda-developers.com/showpost.php?p=34924972&postcount=534
I've only owned this phone since after the ICS update, so never tried any GB ROM.
The ICS ROM I've had the most success with is Re-Calked, but FK23 takes it just a step further for me. I know some people have been reporting issues with FK23, but for me it has been rock solid and has been my DD for nearly a week now.
Blu Kuban also did well with battery life, but it is a little over-customized for my liking. I also had some stability issues with BK. I used sleshpics M'ICS build for a while too ... again, over customized for my liking. Good performance and relatively stable. Also, I have never been able to get 4G speeds on any other ROM/kernel like I'm seeing now.
If I'm in an area with a strong cellular signal, I can get over 24h with 3h+ screen time both on and off WiFi. If the cell signal is week, I burn from 5-7%/h so maybe 15-16h if I was there all day ... but that would obv. improve if I threw it into airplane mode.
I have frozen all of the bloatware apps, don't have Google Now activated. Other than that, I allow syncing to occur per default. I don't have FB app installed.
I use auto-brightness most of the time, and I have a dark wallpaper.
dim screen. stay on wifi. that is all.
Honestly, getting use to a dimmed screen made a HUGE difference!!
Is there ever a time when its better to not be on WiFi, of a WiFi is available?

Excellent! with heavy use of ~ 200 emails a day 1h on internet and about 30min looking up news and 1-2h of calls i get 12-16h.
I tried the best I knew how and I couldnt kill the battery for 2 days. I ran everything at once (not truly everything) and it just wouldn't die.

Battery is ridiculous. After diagnosing my wifi wakelock issue and installing jedi rom I get 4 hoursish per 1% when it goes into sleep, and that's in a basement mostly with horrible reception.
im getting worse battery life ever since the multiwindow update. not sure if anyone else has the same issue, but it seems like tmobile users are complaining about the same thing. it might be due to lack of battery calibration.
Well, here's a visual. Just achieved this impressive feat. 81 HOURS on pure battery! Almost 3.5 hours of screen-on time. I choose to not utilize my phone much over the holiday weekend, so that explains the low screen-on time. Regardless, I think these results are more than impressive. Nothing was restricted on my device. Live wallpaper going the whole time, auto screen brightness (usually a high setting), WiFi going, auto-syncing from emails to Facebook to Twitter, watched a bit of "The Dark Knight Rises" in full-1080p HD, made a bunch of miscellaneous phone calls. I am more than amazed at this phone and its battery. Haven't seen anything close to this in more than five years or so. These results are after updating to 4.1.2 with multi-window, and these are the best results I've ever gotten on this device.
On a side note, if anyone is getting results like the first poster with 8+ hours of screen-on time, it would really help if you described what you typically do with your phone and what you may have done to your phone. Just posting a screenshot tells nothing. You could be web browsing all day with your screen set to 20% brightness, and nothing more. What are you doing? Watching movies? Listening to music? Emailing? Texting? And if you're rooted that makes a ton of difference, so the results wouldn't be exactly truthful or accurate I should say.

Sorry for the lack of detail, I should have included that. I was browsing the net on wifi, playing Words, emailing/texting, various phone calls, watching youtube videos, and spending time on the XDA app. (of course)
I'm rooted and using clean rom 3.5. Auto brightness is on and I'm about 50% on the slider.
Here is where I sit today: (not much youtube though)

^^^ Thanks. So, that does change things, since you're rooted. The reason why I'm making a big deal about it, is because your results (and anyone else rooted) aren't typical results of someone stock. So a person not knowing any better would assuming they'd get your battery results from stock.
How is that possible? I use my note for about 5hrs of screen time and it's at like 3%. I am on an international rom and I undervolted along with perseus 1.8ghz kernel. Even when I did not have perse us, I never got above 6hrs? What settings do you use? I'm on wifi all day with the brightness All the way down. Please let me know! I really want to get that 8hrs of screen on time!

Clean Rom 3.5, I also make sure and close out of anything I'm not using. I also use the ES Task Manager widget to clear my ram before I power down for any period of time.
That's about it, besides not having a ton of widgets running.
I didn't get much over six hours of screen time with my Jedi Rom, but in fairness to it, it was my first rom and I don't think I did it quite right, installing other things with it that probably weren't compatible.

Like Dr. Evo points out, one of the great things about custom roms is they get rid of all the bloatware from ATT and other carriers. Stock I was lucky to have 1gb of free ram at any time, now I'm always around 1.1-1.2gb free without much effort on my part.
