Mines close to stock on purpose but I don't mind people tuning it. What did you change that helped battery? There's bit much from a kernel perspective that will really help battery.

And this topic doesn't belong in development.
[Samsung Galaxy Nexus] aperseghin:
i guess it belongs in general but the idea was to get all the tidbits that we need together in one app specifically for our phones. like "The CDMA Galaxy nexus Super Battery saver app that does it all without all the stuff you dont need"
[Samsung Galaxy Nexus] Smokeey:
Just flash lean kernel and turn off mobile data when you're not using it. No need for these crazy battery saving apps. I get ~7 - 9 hours a day, easily.
[Samsung Galaxy Nexus] hay112:
I consistently get 14 to 18 hrs. I've been using the battery for about 2 weeks now and its awesome.

Rom of Choice: Jelly Belly

[Samsung Galaxy Nexus] rfox54:
Since radios are such a huge drain ...

I think my best move has been using an app called Profile. You can use it to turn off and on WIFI, Bluetooth and change the screen brightness at certain times on certain days. So at my usual time to go to work, WIFI gets shut off. At my usual time to get home, WIFI back on.

Also will change ringers, volumes and vibration on/off (always off uses battery).

24 hours no problem.

Costs a couple of bucks to get the time based control, but works for me.
[Samsung Galaxy Nexus] gchild320:
Two tricks are using auto brightness and using WiFi whenever possible.

However, since I can't stand either of those options, using trickstermod to set max CPU speed while screen off, and setting color profile to morific typically helps my battery life.
[Samsung Galaxy Nexus] tiny4579:
CPU max is capped at 350 or 700 already there's no need to change it.
[Samsung Galaxy Nexus] hay112:
Yah why would you need to lower CPU on sleep when we have deep idle?
[Samsung Galaxy Nexus] admiralspark:
I use CM10 nightlies, and the latest dev snapshots of Imo's leankernel. Min frequency 230mhz, max 1350mhz, interactivex governor with his tweaks and sio i/o scheduler.

I get ~24 hours battery with decent screen-on time, from just texting, about 20 minutes on the phone, and websurfing on full wifi service wherever I go (stays connected even when sleeping, and we have cross-campus wifi here). 3g service only, no LTE here yet. Bluetooth off. NO apps--many of the market "powersaving" apps will just wake the phone from sleep and cycle a few times to write to the log file (any app that keeps track of power consumption, and half of them don't even use the system tools). GPS is on, but it's never initialized more than 1-2x a day for random needs.

Getting a lightweight kernel is a good choice for battery life saving, and getting one that actually keeps up with android mainline is pretty key.
[Samsung Galaxy Nexus] jedil1c1ous:
I think it's most helpful to post your total 'screen on' time and time since charge. If someone tells me they get 14 hours, that means nothing. I can get a full day 16 hours with roughly 2 hours of screen on time, without limiting my phone via turning off mobile data, syncing, or using a juice defender app that disables a lot of things.

That, to me, is not very good at all. I saw that the Nexus 4 is getting about 4.5 hours of screen on time with a full day of being on with everything syncing, etc being on. 4.5 is actually pretty bad also compared to other devices these days.
[Samsung Galaxy Nexus] justavillain:
No matter what I try I usually only get about 2.5 hours of screen on time. I under clock to a max of 750 screen off at 280 undervolted to in each setting.

I've tried many many kernels with many roms
[Samsung Galaxy Nexus] tincbtrar:
Screen on time doesnt mean much me to me because i use my phone for personal and business use, which means I get quite a few calls.

I use the stock 4.1.1 image, rooted with SuperSu and debloated a bit. Also use Faux kernel 23m-sr and his control app.

I roughly get about 2.5 hours screen on time with light calls and about 1.5 with heavy calls - my off charger time is pretty good though as it easily gets me thru the day. I bought another OEM standard battery and just keep one fully charged at all times so I can swap. Works well for me.

I also keep 4g on - why not when you can swap batteries.
[Samsung Galaxy Nexus] t1.8matt:
does leaving gps on all the time if you're not running any location apps bother the battery at all?
[Samsung Galaxy Nexus] mcp770:
No only when you use something requiring device GPS does it turn on. Most background stuff like Google Now uses tower fix so it's OK to leave it on.

---------- Post added at 07:48 PM ---------- Previous post was at 07:43 PM ----------

Battery life is a pretty unique experience for everyone. Apps, ROM, kernel, signal, Wi-Fi time, brightness, etc. Won't say these type of threads are totally pointless but they are pretty close to it. Always good to share pointers on how to save a few minutes of juice though. Ultimately its a big screen and turning it off now and then is the best way to save but personally I leave all my services on because that's why I bought this thing and I keep a charger everywhere I go.
[Samsung Galaxy Nexus] t1.8matt:
ok, wasn't sure if it was one of those things that would constantly draw power or not. thanks.
[Samsung Galaxy Nexus] Phazmos:
worst are usually the apps used that say they will save battery. there's another constantly running service

12-14 hrs on 4g with 2-3he's screen on time, moderate use, is about it with a screen this big. dim the screen to get the most out of the battery
[Samsung Galaxy Nexus] TSGM:
I had a quick look at TricksterMod but how is it comparable to SetCPU? One of the most important aspects of SetCPU is that you can set profiles and use different settings when you run different apps.
[Samsung Galaxy Nexus] ntorresla:
I turn off all auto sync and I easily get 3 hour minimum screen time

hi,

I have just updated my phone with 4.2.1 takju . Phone is working fine but have few hiccups

1.My adb commands are not working anymore (ie it is not detecting the phone). I wanto to restore but when it is trying to start the demon I am getting device not found.

2. My data connection is working even though it is on

3. In my settings I dont have developer tools option any more . Is it because I have rooted my phone ? How will I know I rooted my phone ?
[Samsung Galaxy Nexus] EddyOS:

Go to Settings>About phone and keep pressing the build version until it tells you you're a Developer - you'll then get Dev Options back and you can turn on USB debugging

[HTC Wildfire S] srtjko:
I've been using MIUI v4 for a while now and I want to get my Sense 2.1 Stock ROM back. So I downlaoded RUU for my phone and because I have some errors (Error 155 UNKOWN ERROR) I decided to export .zip from that .exe file. After exporting I renamed rom to PG76IMG.zip and put it on SDCard root. I went to bootloader and it found the .zip, progress bar came up and everything was fine. After instalation when I rebooted the phone, MIUI booted, not the stock ROM. Like nothing happened. I need ANY help to get back to stock ROM, if someone can make a backup of it so I can flash it in CWM It would be great. ...I also tried flashing that PG76IMG.zip with CWM but it said the zip was (bad).
[Captivate Q&A, Help & Troubleshooting] jamina1:
Hey guys,

I love my Captivate and I don't want to have to replace it but I'm having serious issues. I installed Cyanogenmod 10 and Devil Kernel and overall its been working ok. But the phone is SO SLOW! From wake up, it sometimes takes about 5 - 10 seconds before it will register that I've done something and even then it takes another 5 - 10 seconds to start an app. Rebooting helps for a little while, but the slowness comes right back.

Most of the time it will freeze up after an input and then do everything I asked it to do in about 2 seconds, then freeze up again.

I've got it OC'd (which I had hoped would help) and I'm using wheatley governor in Devil Kernel. Doesn't seem to make a difference over stock settings. No force closes or instability just absolute gridlock when trying to do anything. Any suggestions or ideas?
[Captivate Q&A, Help & Troubleshooting] BWolf56:

[Captivate Q&A, Help & Troubleshooting] jamina1:
Thanks for the tips! I am really good about closing apps that I am not using, and I try to restart my phone at least once a day (but that really shouldn't be necessary). I know Android and task killers don't get along - any suggestions on something that might work?
[Captivate Q&A, Help & Troubleshooting] BWolf56:
Have you tried the Devil settings in the link?

As for task killers, I personaly use ATK (no auto-kill) when I know I'll require some extra RAM for what I'm about to do but unless you have some rogue app taking all your RAM, 5-10 seconds lock shouldn't happen.

Slow performance usually comes from lack of free RAM, therefor, there has to be something (app most likely) using too much. Other thing could be that your phone is too full, so either too many apps (100+) and/or not enough free space on your SD card (less than 1gb).

Does it happen randomly or with specific apps? If specific, are those apps from restore or fresh install?

[Galaxy S II Q&A, Help & Troubleshooting] postfatal:
I agree with OP... custom roms are made by people just in their spare time etc. whos going to be able to make a better ROM, the dozens of professionals Samsung actually pay money to make the ROM or some spotty kid in his spare time? The answer is obvious... even CM isn't as good because it's just based on the work Google already did. And google's work is obviously better because it's made by professionals.
[Galaxy S II Q&A, Help & Troubleshooting] kilometers4:
I don't agree with that. There are so many devs in here that are better than the paid devs. Sure there's some that have a rare bug or two bug at least they get fixed in a timely manner on here. Look at the 4.2 debacle by Google.. It took them a whole to fix all the issues with it, when devs here wouldn't release it with that many bugs..

Just my 2 cents
[Galaxy S II Q&A, Help & Troubleshooting] postfatal:
LOL you think a random kid on XDA is going to be a better developer than someone who is PAID by samsung/google to write code for them? yea noooo. i dont have any custom ROMS because why would I choose to use something worse than I get from the start, only rooting is worth it every other custom ROM I have tried has had less features, worse performance and worse battery than stock... cant believe people still use them tbh.
[Galaxy S II Q&A, Help & Troubleshooting] kilometers4:
Wow. How would you know what you're talking about if you don't try it. There's obviously going to be buggy ones, but when you find one that isn't you realize what you were missing. And yeah people here make better stuff than people getting PAID to make it... That's pretty sad if you're samsung..
[Galaxy S II Q&A, Help & Troubleshooting] postfatal:
actually i've tried over 80 different custom roms and more kernels on my galaxy s II and none were better than stock... i used rootbox 3.0 for a day and the battery life was AWFUL. seriously know what youre talking about before you come on here and argue. sorry but samsung do what they are paid to do better than some random guy in his spare time. if it werent for samsung there wouldnt be an XDA so yea... think about that.

haha no. my battery was awful because of the ROM not because I use it for a day, i used samsung stock for a day and had great battery. erm well samsung galaxy s II is a SAMSUNG phone and so there would be no galaxy II forum.. and galaxy s II is by far the most popular forum so if there was no samsung there would be an XDA but XDA would just be way smaller. this site is basically dedicated to the s II anyway most other android phones suck tbh and google knows that, thats why they let other companies use android so they can benefit from their work... apple does all the work themselves and still makes better phones.

[Galaxy S II Q&A, Help & Troubleshooting] Kaldius:
Of course I've tried the CM9, CM10, AOKP and other such ones but the one Samsung offers has better support for the things I use my phone most for such as the camera especially, radio, video playback and all in all its just more stable the custom one's have the phone locking up or rebooting itself sometimes, reported by many users.

Those are the top things I can think of for me maybe your a different type user and these things don't matter for you. Also I like the little extra apps they add the Voice Recorder is really good.
[Galaxy S II Q&A, Help & Troubleshooting] king_below_my_lord:
I partially agree with your view, but in case of battery life my current rom CM9 stable is giving me the max life ever and phone's performance is way more higher , and yeah custom roms definitely have more features than stock roms, but custom roms which are not based on Samsung stock roms certainly lack important features like, Wifi direct, fm radio, fully capable H/W decoder (files like .avi are not supported), yeah I know Wifi direct is present in CM9 and yes we can connect but we can't send any files which makes it pointless, likewise there can be several problems in custom roms (even stable one's) which becomes evident when we use it for some time.

And also if battery life going haywire after installation of a custom roms is a common issue try wiping the battery stat file, or just charge the phone from low battery a couple of times.

[Galaxy S II Q&A, Help & Troubleshooting] king_below_my_lord:
Uhm by video playback, noobs refer to H/W decoding(ie in stock most video formats are supported flawlessly) but in most custom roms H/W decoder doesn't support all common formats like avi.

The above in noob language :

A fully capable H/W decoder will let you play almost all video files directly from the Gallery or Video app without using any other 3rd party app like MX Player (which compensates with S/W decoder which is also slower and a battery drainer). This feature is absent in most custom roms (mostly non-Samsung based roms).

And I have seen custom roms having fully capable H/W decoder.
