Someone help me! (BatLife woes)

Alright I wasn't going to make a thread on this because this topic is already discussed elsewhere naturally but I feel my situation is different. All over the place I see people reporting great battery life with ICS.. well mine is HORRIBLE. I just flashed the latest nightly for Pete's bugless. I didn't change the kernel. Everything is stock. Only a few apps installed. Noop for scheduler and ondemand for governer.
The phones been off the charger for 55 minutes and I'm sitting at 76%. Idk what's going on. I've tried so many rom/kernel combos and I seem to get the same exact battery life no matter what. Around 6-9 hours with less than 1 hour of screen on time.
Things I've tried to combat this:
Undervolting
Freezing apps
Restricting background data
Underclocking
Brightness set to auto
And I'm sure a few other things I'm forgetting about. I've done all this and still get ****ty battery life. I've flashed the new radio hoping that it would solve my issues but no dice. My signal strength reports at -67 dbm yet the bars never go over 2. 3g or 4g. Even after updating plr.
On gingerbread cm7 I ran brightness at 70%, ocd to 1.4ghz and always got 15+ hours.
For the love of god someone help me. Cuz I think my phone hates the cream sammiches.

try this kernel, trinity teuv underclocked/undervolted kernel, oc'd gpu http://goo.gl/rY6ga
and do not set brightness to auto, its a battery killer. i keep my brightness at about 20-25%.
also, be sure to fully discharge your battery then charge it completely, after 2 or 3 cycles you should be good.

I do this every day lol I let the battery drain to around 15-30% before I plug it back in.
Screenie: 1 hour later and I lost another 25% this can't be rom or kernel related. As I have tried trinity already and the same thing happens

Ugh. Another 20% gone. Its only been a half hour from the above screenie. You guys see my dilemma? Lol **** me.

i was having horrible battery drain after flashing a new rom & kernel - i finally figured it out that my APN settings were messed up and I re-entered them according to the correct carrier settings.
i don't know if that will apply to you since it looks like your 4G data is working properly, but since I was on wifi 99% of the time, as soon as I went off, my data didn't work. but it's something to look at.

4 hours later I'm down to 4% from a full charge.

Could you try better battery stats to see if something is holding a wakelock?

Turn Data usage off :/ i think Fb or some app is using your 4g

I would be interested to see what your battle life diff is without 4g switched on. Also in that 4 hrs what was ur screen on time?
Have you thought of trying a new batt? Just got an OEM Samsung for 5 bucks on eBay. Worth a shot.
Oh remove fb app it blows...install friend caster way better less batt make sure you change the sync interval.
You could also try green power from the market to manage your data use while screen is off.

Ok here's how my battery performs back in cm7 nightly 174 gingerbread. Almost 4 hours and only 25% chipped away. If you look above you'll notice I lost more than 40% in the same time with ics. And I'm doing nothing different. I'm even overclocked to 1.3ghz ondemand with noop for a scheduler.
I think I'm sticking to gbread until official source is out. Maybe then ill get the same battery life.
Sent from my Nexus S 4G using xda premium

That is really weird, if you have time try Milestone 3 and SG's latest kernel and just leave the settings stock . I get wonderful battery life with it hopefully you do to
Oh and are there any apps you are using on ICS that you aren't on CM7?
Sent from my Nexus S 4G using XDA App

Nope. Lately its only been a handful. I actually have more apps installed on gbread to achieve some of the features that are baked into ics. I just don't get it. Ics hates my phone. I even used the GPS today. So weird.

This. If you are installing the same ol battery-draining POS app then you are not going to fix it with any rom or kernel.

So you guys think my batter watcher widget is preventing my phone from sleeping properly? Ok.. I'm on cm7 right now. Battery is def back to normal. And this is with bacround data on. Ill delete bw and get better battery stats.

Better battery stats is not the same thing as other (mostly useless) monitoring apps.

Look. 16 hours on gb. If none of my apps are killing the battery then what could it be?

What kind of apps do you have?? Like apps that you think might drain some battery. Also use betterbatterystat app to monitor what's waking your device.

With stock, around 2 hours of screen on time is typical. You can prolong the battery life by disable Google Now, location service, email sync, Playstore auto update, etc. Check your battery stats (try better battery stats from the store) to see if any third-party apps drain your battery.
The better way to do it is to unlock bootloader, root your phone then flash a custom kernel. I recommend franco.Kernel. 3-4 hours of screen on time is typical with franco.

Might as well flash a custom ROM with it if you're going to use a custom kernel IMO. When a new OTA, OP will have problems updating to it because he is using stock + custom kernel + custom recovery.

Here is how to fix your battery problem.
1. Turn off location access in Google Maps settings.
2. Wait about a week for the battery to go through its charge cycle 6-10 times. Let it get as low as possible without the battery dying (this is really bad) and be sure to let the battery sit at 100% for atleast a half hour or so when fully charged.
Each day you will see your battery life increase and when done, you should be getting around 5 hours screen on time.

Well dramatic change in battery life as displayed below. Now after having a read in several topics it seems like a fix is to have the wifi on. How strange as this goes against the ethos of all previous smartphones i have owned i.e. wifi on drains battery. I have uninstalled a few apps and also switched of location access, so to be sure that the fix is wifi related i will switch wifi off the next time i do a full charge and see how that behaves. By the way android os is way down in battery consumption now.

Massive battery issues

Hello folks.
I'm currently on Aokp 4.2.2 unofficial with Francos r90 Kernel, bootloader and Radio are both updated. I'm suffering from massive battery draining. I guess something isnt letting my CPU sleep properly, as i always get messages like "100% awake while screen off" from battery stats plus. I'm just getting up to 2 hours screen on time, and battery is falling by about ~7% / hour With normal usage (whatsapp, News, xda) and like 15 Minuten screen on time in that hour. Also, see the attached Images. I sometimes have wakelocks by audioOut_2 and as you can See, maps is using more battery than the Display itself.
On an additional Note, GPS is always off, im using Taster to locate, but with cell near only.
Would be very Kind to help me out of this issues, thank you a bunch!
Sent from my Nexus 4 using xda premium

Turn off Location Services for a little bit to see if that helps.

You should try a program like autostarts, and don't allow things to run unless explicitly started by yourself. This way it'll help identify if there is an misbehaving program.
I saw you were using franco r90 which could be an issue. Try going back to the last stable

I think you will like this application.
https://play.google.com/store/apps/...GwsMSwxLDMsImNvbS5vYXNpc2ZlbmcuZ3JlZW5pZnkiXQ..
This simple application will make your annoying applications to go to sleep. Therefore your phone can finally go to sleep like it should when it's not in use. I see that Google maps seems to be the culprit in your battery drain. You can use titanium backup and delete it and install it back again from the play store. After that you can use the application that I've given you and force it to go tot sleep.
Here's the forum for the application:

Coming from the iphone 4, good battery life is the most important thing i miss. I need a rock solid reliable phone or else would have started to mess around a read about Kernels to see how they may help with better battery life. My iPhone would last me 3-4 days of general use. To me General use is very light use..! With nexus it lasts max 1-2 days but more importantly i need to be concious what the battery level is. With th eiphone i never really bothered as i knoew i would get at least 2 days if not more.

Still got audioOut_2 wakelock. Except that onr, everything is fine After Kernel update, greenifying and disabling Autostarts

That is outstanding. But how in the world is it possible that you have a "screen on" state without being awake?
I have been fighting battery issues for so long now, I'd really like to get to something as good as what you get...

i get 5 hours on heavy use until i hit 10 % well my setup is in my signature on light use i am sure i can stretch it to 6 hours with brightness on auto and wifi is on most of the time

battery life is never going to be better for me unless i uv. the previous setup, i used cm 10.1.2 stable with matr1x kernel. i uv and set the max cpu to 1350. it was really really good. i can use the phone from 8am to 9pm.
now currently using aosp 4.3, the default setup battery life has improved a bit compared to 4.2.2 stock, but after semaphore kernel installed and uv a bit, even with max cpu at default which is 1.5ghz, battery life has been really great.

Just out of curiosity, are in you the US/North America?
I had the same issue of losing tons of battery to the OS overnight. I reflashed to an older version of the modem. Most of the people I have seen so far with these symptoms have been in France and India. Must be something about the cell services and how they interact with the phone.

@Calebz: I'm in Ireland.
I've restarted the phone since and the battery usage is back to normal, will see for how long.

I faced the same , but after i rooted and flashed franco's kernel, im getting around 22hr on normal usage ,10-11 hr on heavy usage not to mention almost 2 days when phone is idle.

Keep in mind that after an update or a ROM flash or what ever changes are made.. Battery life can suffer for a good week or so. This GS like media scanner and other services will be running more in the background.
