battery issues/help - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

So I love my gs3, and I love it way more with cm10. I am running the 10/1/12 nightly with the k47 kernel, I made absolutely no changes to the kernel, I just flashed it, wipe data,cache and fixed permissions. its the one from 9/23/12. but my batttery life is absolutely terrible, Im at work and in about 6 hours with maybe one hour of actual use its down to 34 percent. this is the screenshot of what i am getting. what is media server and why is android os taking so much batter when idle? any help would be great...I have flashed many versions and always wipe of cm10, and I end going back to a sammy based rom for that reason, but i really rather keep cm10. I live in an LTE market btw.

[Q] CM7 ROM Questions

Long time lurker first time poster... so don't beat me up too bad.
I'm looking at jumping into the CM7 world and am looking for some input.
I've used multiple versions of Skyraider up to 3.5 and loved them until they began getting a bit laggy (tried multiple kernels). I'm now using myn's warm 2.2 and ziggy's kernel with great success. Phone operates VERY smooth and all features work (not even sure why I want to try something new... guess I'm bored?).
Long story short, my phone is a daily driver and needs good battery life and all features to work (BT, camera, data, WiFi, etc...). I don;t mind flashing a few ROM's but it gets quite time consuing setting up the desktop screens, apps, calendars, etc...
I see that some builds break things, some fix things and it's hard to know which build does what. Many folks feel CM7 is the greatest thing since the Atari 2600; so here's my question:
What build are you using?
Does the phone scroll and transition smoothly?
All features working?
Getting FC's?
And yes... I have done quite a bit of reading on the CM7 nightly thread and others as well. People have a tendancy to post issues, not sucesses so it's difficult to find a good stable GB ROM.
Im on the latest release #37 I believe Using slayhers .37 kernal.
Love it. Altho, ever since I installed .37 kernal I've had my phone randomly reboot between 7:30 am - 9:00 am
I have yet to find out why... and it's only durring those hours too
I'm loving this ROM. Every time i go back to a sense, rom, i end up flashing cm6/7 back.
There are good things about cm6 and cm7... cm6 has a better camera app, probably more stable, but cm7 brings all the little things together, like multitouch keyboard + maps, it's snappy, the txting lag has been much improved. I think they are going to drop RC1 tonite..
I'm using build #33 with Chad's.37 kernel and everything's been running perfectly for the past few days. I don't think I've had a single FC or reboot. Battery life has also been very good, been using it pretty heavily all day and I'm down to 50%.
Just flashed 38, Have also used pretty much all the 20's 31 and 32. .37 Slayher Homebrewed #14
No reboots. I would say I could count the FCs on one hand easily and honestly don't blame the build I blame the app.
I used a number of roms before. Most of them from Rom manager. Now I am strictly a CM guy. Love these builds. I don't use Rom manager anymore either, just manually flash.
Personally, I'm someone who generally avoids experimental roms that still have incomplete functionality. Like you, my phone is a daily driver and I need to be able to rely on it. But CM7 was getting such rave reviews, I started to read up on it. It seemed that by the time I was hopping onto the bandwagon (nightly build 27 or so), everything was functional, there were just some things to be polished here and there.
It would be an understatement to say that I've been pleased.
To answer your questions specifically:
What build are you using? - Just flashed to #38, but have used a number of the builds
Does the phone scroll and transition smoothly? - Yes. For whatever its worth, I use LauncherPro Plus rather than ADW (which is what CM7 comes with)
All features working? - Yes. At least everything that I use.
Getting FC's? - Nothing that can't be traced back to another issue besides CM7
Don't get me wrong, I've had some tiny issues here and there, and some weird interactions, but nothing critical, and nothing that has stopped me from using this as my only rom.
I still keep old nandroids of the last two roms I used before CM7, but unless something drastic changes, they will just collect dust.
I've been using CM7 as a daily driver since like build 11, I haven't had any problems at all and its nice seeing new things added with each build
My dinc runs CM7 with the modified slayher .37 kernel. I runs super fast, but I haven't really noticed a significant increase in battery life. It used to crash, but since I set the wifi sleep policy to never, I have not had any problems.
build#38 ran awesome. no force closes and great battery life 20 hours or more. id say give it a try.
Just flashed RC1. Going great so far with only a few FC's that were solved with a simple reinstall.

Did RC1, shaky, but amazing. Running 39 and it is better, has a lot of fixes that RC1 was plagued with. Like the rotary lock in the call screen.
I've been following CM7 development since Crackflashers. The rom has come a long way. Many people had problems with the first RC1 release because a mistake was made and those who did a clean wipe were locked out of the system. -Guess that should serve as a lesson to always nandroid first-
My advice is to continue flashing nightlies. As previously mentioned, the code will continue to improve and you will receive the latest fixes and features. Save yourself the trouble and clear cache and Dalvik before every flash. No need to wipe data.
Does anybody happen to know if there is a .37 version of the invisiblek kernel that includes the wifi sleep policy fix?
Its been working fine for me. The only problem I am having is that trackball wake doesn't function. I've made sure its selected int he CM settings, but I can press the trackball until kingdom come and it won't do anything. Looking at the dev. thread, I'm either the only one experiencing it, or the only one who cares.
SD card not mounting
flashed CM7 yesterday, really like how it runs. problem is my SD card won't load on the phone! I tried two different cards but no luck. recovery won't mount them either so I can't restore a nandroid backup. help!
also when I reboot most of the time, it'll show the htc incredible screen then go black and vibrate 5 times.
I'm running CM7 nightly #2 with the 2.6.37 incredikernel and it's great. Everything is very smooth and I can't seem to find anything that refuses to work. I had fc's when I first flashed the rom but fixing permissions in rom manager did the trick, since then I've had no problems.
I flashed CM7 as soon as they posted RC1 to ROM manager. I was skeptical at first and had a bunch of FC issues until I ran fix permissions (AFTER you install all apps). Haven't had issues since and my battery is lasting longer than ever, even without Juice Defender. Performs great. Can't wait until they get to adding more features like 6.1 had.
Sent from HTC Incredible [CyanogenMod 7 RC1]
Is it just me, or did Cyanogenmod lose some customization options from CM6.1 to CM7?
I dont see many editing options under CyanogenMod Settings and miss the ones from CM6.1
I'm on Build #41 and I can say a few things:
1) Battery life sucks on the Incredible no matter what. So just accept that. That being said, with Incredikernel .37 and CM7 Build 41, my battery life is "acceptable" compared to completely unacceptable with any other kernel or Sense Rom combination.
2) Random reboots. I don't know if it's just my phone, but even after trying three different .37 kernels, fixing permissions and re-flashing, my phone will go through "reboot anxiety attacks" where it reboots once every 10-12 minutes and then it will be fine for a whole day. It's not at specific times either.
3) Honeybread Theme - Get it. That's all.
4) Turn off wifi sleep completely. It seemed to curb some battery issues I was having.
Thanks All...
I went ahead and took the plunge and I don't regret it
I had some issues with RC1 and had to go to nightly #38. Everything has been solid with the exception of 2 random reboots (in the last 3 days). Not sure why but this isn't a show stopper.
I'll likley wait a while before flashing another nightly build.
So far so good. Batter life is ok... I know the Inc isn't the best for battery life but I got a bit better with Myn's ROM.
My quadrant numbers have improved (I know... relatively meaningless) and the UI is quite smooth.
Thanks to the development team... You've done a great job !!!

[Q] High battery drain (CM7)? (Current widget log attached)

Hi,
I flashed CM7 (nightly 213) as I'm looking to try AOSP instead of sense for a bit. I'd heard great things about the performance and battery. Today however, I didn't use my DHD too much - a couple of short calls and some texts, the screen was on for 1hr15mins.
Before today I restored some apps with Titanium backup after flashing and used LordModUE's kernel (2way call recording, BFS), wouldn't have thought that should cause high drain though?
Display only used 8%, in sense it regularly used around 60%. I doubt it's using any less power, just other things are using more! Any tips would be greatly appreciated!

If you were simply looking to try out an AOSP ROM then you probably shouldn't have flashed a nightly build of CM7. That could be the cause of your problem, since from what I know, nightly builds are intended for the more experienced users.
I suggest trying out a more stable build, either from the CyanogenMod site or a custom one from here!
I flashed a nightly thinking it would be the most up to date, bugs gone, etc. After reading a bit more I've realised that's not the case! I've just backed up and will try CM7.1 RC1 with the stock kernel.
If battery life is good I'll try LordMod's kernel and add up slowly; I put too many things on at once so it could have been anything really!
I'll come back in 24 hours and see what's improved
My experience with the rc1 is bad and nightlies builds currently seem better.
Sent from my Desire HD using xda premium
I use CM7 RC1 and I have to say that my experience with this ROM is more then satisfying. Battery lasts something around 20 to 48 hours (on weeekends when I don't receive so much mails, 20 hours is something I get on normal working day when I receive around 50 mails during the day) and I have 5 mail accounts online all the time, everything set to push and Facebook, LinkedIn, googletalk and so on. But, I do not use any application to retreive my aplications from backup. I just install them manually one by one. And don't forget about calibrating battery after you install new ROM, it helped me a lot. Also, it is possible that you have some aplication which is draining battery and you are not aware of it.

I assume that you didn't restore system data via Titanium, yeah? Coz that would be bad.

Best current ROM/Kernal?

Hi all,
I'm a new Nexus user and I was just wondering what is currently the best ROM and Kernal people are using. I put Android Revolution HD on my Nexus a few days ago and it's running great. I keep hearing people talk about Cyanogen or the Franco kernal though.
Are the performance improvements that much better, or should I stick to Revolution? I don't require a lot of personalization in terms of how things look. I'm quite happy with the stock look of the phone. I just want all the "behind the scenes" improvements like better battery life and loading times. What's the best setup in your experiences?
Thanks!
I've played around with several of the roms and kernels, with mixed results. It seemed like some roms and kernels would get me crazy performance, but really crappy stability.
The setup I'm running now is a cleanly wiped install of GummyNex 0.8.1 found here, or more directly here OnDemand governor is giving me respectable battery life. When I'm running short, I'll switch to Conservative. I've been meaning to set something up in Tasker or Setting Profiles to do it for me.
And Google apps found here, also more directly here
The kernel I run is Trinity, found here
If you haven't done so already, I found awesome performance improvements by opening the egl,cfg file in /system/lib/egl/, and deleting the first line- usually "0 0 android". Then going back into the egl folder and deleting both the .bak file some editors create, and the "libGLES_android.so" file. This is an ICS tweak that alleges to eliminate CPU rendering. I know there's an option in developer tools to "force GPU rendering", but apparently that doesn't quite cut it.
Anyway, that's my 2 cents, and it's blazing fast and stable. Averaging around 3800 in Quadrant.
Thanks! Revolution HD already does GPU rendering so I'm not to worried about that. I guess I'll just stick with that since it's basically stock with a few performance tweaks. I'm not big on instability :/.
The Trinity kernel looks interesting though... Is the overclock safe though? And does it drain a lot of extra battery?

Revolution HD is based on 4.0.2 so many kernels will not work because they are based on 4.0.3 and 4.0.4. I highly recommend you use a rom that is based on 4.0.3 AOSP (Such as GummyNex or AOKP). 4.0.3 has better stability/battery/performance tweaks anyway. If you want a better selection of Trinity's kernels go here. TNP1344-ANY-384-aelp (dated Feb 27th) is really nice. If it gives you bootloops up the voltages by 50 or 100.
aokp.27 + glados.v.1.18 OR leankernel.v.2.4.0 (both are stable as a rock)
Alright, I'll try Open Kang I guess. I'm so new to this... Sorry for all the questions :/.
It seems like a hassle to reinstall all your apps often so that you can switch to a new ROM . Does this need to be done every time the device changes its firmware version?

Well... you can always backup your apps with Titanium Backup, and save all your preferences (such as Nova Launcher, Minimalistic Text, etc.) and then reload that. And usually if you stick one one Rom and then an update comes from that rom, you don't have to wipe data (just cache & dalvik cache). But if you're switching Roms, then yes, you have to reinstall all your apps.

with titanium pro its a matter of minutes, saves your app-data also, so you don't loose your highscores. but as was mentioned before, updates go through without factory-reset most of the time once you're settled.
btw, aokp is perfectly stable.
I'm running gummy with the latest lean kernel and love it. Battery life is great and performance is top notch. Big fan of team gummy. I get a solid full days use regularly. usually around 20% when I plug it in after 16 hours of use and I use it fairly regularly, wifi, 4g, txt, web, etc.

Anybody Returned to Stock after trying different mods and Kernels? Tell us about it.

Hi,
I have played with my Gnex for the Past 4 months (Released Dec 8th in Canada). I have installed many mods, kernels, ROMS (Currently on AOKP MS3 and Francko Kernel MS1). I love the utilities provided by these custom apps, but I keep having stability problems from time to time and its getting a little bit disapoint.
* My Juice Def apps gets killed and settings are reset.
* I only see 50% of the pic when people call me.
* Volume is at max, but cant hear my music because of ambiant noise (to tell yuo hoe low the volume becomes)
* I Dont know how to use he Undervolting and Overvolting of the CPUS, and I dont realy care (Too technical for me)
* Whatever ROM is used, it still sucks my battery. Juice Defender is very good at doubling my battery life.
These are some reasons that I might bo back to STOCK KERNEL and ICS.
For those of you who returned to STOCK, Did you miss all the tweaks ROMS and Kernel gives you? Do you notice a different in speed?
Thanks.
Sounds like you're overall not happy with your experience.
If all of these cool tweaks are making it so you can't regularly use the phone like you like it, just return to stock. Its not worth sacrificing your enjoyment of the phone just to get some cool tweaks.
Problem is.. I dont really remember how its to run a stock phone. :S
same here..i also would like to go back to stock..

Then do it! No one's stopping you. There is no shame in returning to stock lol. Its okay.
I want back to stock for a day and changed my mind.... main reason that I don't like the stock is lack of toggles and overall smoothness. Oooo and you have no idea how often I use search icon on navbar . Also this is my main way of communicating with people. Voice actions are brill testing and calling is very easy with this. Someone will say that I can do that from search bar .... yes but 9 out of 10 times I'll miss tapping the icon ....

Did I return to stock? Well, after successfully compiling my first ROM (AOSP 4.0.3) I found out that my backups were deleted so I had to reflash some stock images from Google. I'm having enough fun playing with the phone on my own...I can be patient to see what improvements other ROMs come up with.

I am running AOKP MS3 and have been flashing the latest Franco kernel. I had the same issues as you and a full wipe and reflash solved all of those issues. Hope this helps you!

1. I use juice defender too and I NEVER saw it getting killed. The settings do reset everytime you flash something even if you don't wipe cache but that's the developer's problem no the roms/kernels. The solution is simple : just backup your settings from JD's status tab and restore it after you flash zips in recovery.
2. Well known issue with m3. there was a fix zip floating around but you should just update. m3 is not anymore stable than the newer aokp builds. b26/27 are very stable but just wait a few days and m4 will be out for sure.
3. I'm not sure what you mean by that. Are you saying you can't hear the music at 100% volume? Does it go away with stock kernel? then it might be franco's volume hack. Try leankernel 2.4 if you want something lean, fast, with GREAT battery life and without all the extra bells and whistles. you need to go to rootzwiki.com to dl leankernel.
4. You don't need to undervolt with gnexus and even if you do, it's completely pointless. It causes instability and the battery savings are negligible.
5. Wipe data and cache and flash leankernel 2.4 and aokp b26 (or m4 when it comes out). You'll lose all your settings but I think this combination will keep you happy for along time.
6. I used JD Ultimate for a long time and after a lot of testing on leankernel 2.4, I find it completely redundant.
I'm back to stock (stock launcher too).
It's because I've never had any real problem with stock in the first place. No battery drain, no dropped calls, no sluggish interface and everything works. Then the most important thing is I LOVE the simplicity feel that stock offers so I've decided to go back to stock.
Nothing against custom ROMs.
This is why after you root its always good to Nandroid your stock rom.
The only thing i like about stock is that i know its not going to fail me and i know i dont have to always mess around with tweaks and other things.. it just does what it was meant to do..
Custom roms seems to always have problems with different kernels or maybe the ROM is just in beta.. or a tweak is causing something else to break..
But we also have some good custom roms base off of stock with nothing too much added.. like Android Revolatuion.. No diss towards other roms tho.. just people dont want to always have to change or fix something

It all comes down to personal choices really.
To me i tried AOKP rom with Franco kernel and it really rocked. But then i went back to stock since 4.0.2 with XXKK6 gives me good battery life and its rock stable.. no issues. i do have to give up a lot of customizations but i can live with it. no problem.
The reason i don't want to install custom roms yet is that i would go crazy with flashing roms and it would be addicting so right now i just want to stay away..i would get bored after trying all new roms.. so right now STOCK.. just want to savour the beautiful Galaxy Nexus as is.
I went back to stock on Sunday. I was checking to see if wallet would work on stock but it didn't. When it booted up stock the first time I was like:
http://troll.me/images/snape-dafuq/dafuq-is-this-****.jpg
When I got my phone it was stock for about 5 minutes. AOKP FTW!
Confused. You can run ROMs with the stock kernel. IMHO, stock kernel> any custom kernel. My experience, custom kernels create different problems.
Kernel enthusiasts tend to be a little... too enthusiastic. They tend to ignore the problems and measurebate about supposed battery life or performance.
My best combination is AOKP ROM for the features and stock kernel with a couple performance tweaks in the developer settings.
Now I just go about using my phone to enhance my life rather than the other way round.
YMMV, and it is your life, of course.

I agree 100%.
I never had any issue with AOKP. But I use stock kernel. Custom kernels are for those who can live with a phone not working 100 % and alarm clock fail to ring in the morning. If you want the best of the best for the Gnex, flash AOKP, and nothing else. And don't mess with performance settings.
And btw. The only ROM that ever randomly rebooted on me, was stock ROM. How is that for a laugh?
Stop using Juice Defender. It sucks or it has some serious bugs on Nexus I don't know. Stock everything I had juice defender on and strange things were happening. Touching screen would do nothing, apps would close on their own. When I took it off everything was fine again. Juice defender was recommended to me by someone else. So oh well, seems he was luckier than me running it. Fast forward a week, I got interested in ROM's, now running AOKP with Fugumod kernel and thought hmm maybe give juice defender another shot. Within 1 day I removed it. AGAIN, apps crashing, touches not being recognized, slowness switching screens. I say Juice defender stinks or has lots of bugs. My battery life is just fine with AOKP and Fugumod. Right now my Nexus is perfection. I can quickly get in and out of apps and there is no slowness or anything. I can't see myself ever going back to stock.
I'm running stock 4.0.4 with no issues.

I'm debating going back to stock.
Came from 4.0.2 stock to AOKP 1-30 milestone + franco.
The new ROM is nice and all, but like every 15-30m I get randomly disconnected from the network and takes 15s to reconnect. It's semi-tolerable but I hate things like this.
why was music app missing from AOKP rom Milestone 3? who do you get it back?

Best ROM for battery life + stability?

I have been running Slim-vision 4.2.2 build 6.2 on my Desire Z for the past month and a half; since upgrading from stock gingerbread.
Unfortunately there are a variety of major issues with it, namely:
Kills battery (1-3 hours battery life now :\)
Unstable (almost all apps freeze)
Unstable (sometimes turns off randomly)
Inaccurate stats (battery is on 87% one minute; the next I get a "very low battery" msg)
Calendar app is broken (had to remove it)
So my question to you is, of all ROMs available, which has the best battery life + stability?
Thanks for all suggestions
I have been using Slim since it came out and don't experience the problems, once I had a clean install.
I did run into the Calendar app problem. The cause was running the wrong addon version. Here is a link to the correct version. You want build 6x, if use current build you will have difficulties.
http://slimroms.net/index.php/downloads/dlsearch/viewcategory/766-slimbean-4-2-2-build-6
I suggest you read the install instructions and the full thread for other helpful tips. Make you do a full wipe.
blk_jack makes a wonderful ROM, Mimicry is ICS ROM that is very good.
Check out other apps for battery drain or installation issues. Any issues I encountered where non-Slim behaving poorly. In the thread there are a lot of recommended tweaks.
I have using G2 since it first game out. It doesn’t matter what ROM I used I good only get 4-5 hours of battery on continuous use (screen on). Right now my phone is at 43% and I have not charged in over a day.
Go luck.
G2 using Slim Bean
For battery life & stability, I would have to say G-Lite. I always seem to go back to ILWT CM7 because I can't handle how slow ICS & JB run on it. With CM7 you get some customization and don't lose out on speed. =)
