4.0.4 heavy battery drain

Hi,
Has anyone else had problems with the battery draining with the new 4.0.4 ? My GF Nexus S was still on 2.3.6 so I got the factory version of 4.0.4 and installed it. I obviously wiped the data/cache/etc. Also I rooted it with the latest superuser.
I'm running the latest nighly of CM9 and everything is perfect, so I thought it was time to give her the sweetness of ICS.
So with all that useless information, has anyone found a fix for the battery drain in 4.0.4?
Thank you,
WarpedMonkeys

Since I installed 4.0.4 my battery lasts up to 20 hours, no problem at all.
I'd suggest manual full wipe with fresh 4.0.3 stock rom and then manual ota update to 4.0.4.
I'm also using matr1x kernel, it's just awesome
Hope it helps

Yeah, me too! Try another ROM. I am currently using CyberGR-MOD|NS.NGN ICS v10 HYBRID and getting superb battery life (and performance, mind you ).

Stock rom is ok, but updating with ota from 2.3.6 to 4.0.4 may lead to bad battery behaviour. Someone says that battery stats wipe could lead to better battery performances, but I think fresh install could do the trick

I used this thread : http://forum.xda-developers.com/showthread.php?t=1445621 and installed:
Android 4.0.4/IMM76D/UCKJ1 Radio/KL1 Bootloader
Official factory fastboot images, must be flashed using fastboot on an unlocked bootloader. Contains recovery, radio, and bootloader.
THESE IMAGES MUST BE FLASHED USING BOOTLOADER VERSION I9020XXKA3
I can't really be more fresh than this. I'll try messing around with her settings, but if it doesn't get better, I'll just flash her the latest CM9 nightly

Check your battery usage, if Android OS is using more than 8-9% after some regular usage, then that's the cause.

Ehhhmmmm... My Android OS usage is always around ~20%, but my battery still lasts ~15 hours. Heavy usage. Are you telling me that it should last even longer?
Anyway, AMOLED screen or sLCD?

Her Android OS is normal...I really don't understand why it's that bad. I'll try doing a full battery cycle.

Updated form 2.3.6 stock to 4.0.4
OTA and battery usage is still OK. Lasts about 1-1.5 days. Permanent Wifi or 3g, internetusage and some gaming-No probs!!!

A full battery cycle could do the trick. Don't let it die, anyway, because it can cause battery wear... Just take it to 10% and recharge it nighttime... You may also wipe battery data before, if you wish...

Check apps like news and weather too. My news and weather app really acted up after my ics update and wouldn't stop pulling data. I had to shut off any automatic updating with that app and it fixed my issue. It might have been temporary but just check your apps.

Alright thank you I'll check those out.

Try Badass Battery monitor . it will give you some good info on whats using your battery. Gives you a % of app usage
Look in play store

OMG thank you, I didn't notice that. Maybe I can get even better battery performance now it was set to update every 1 hour, so it may be not much, but even 1% is good for me!

Heavy battery drain ??? i don't have any issues with it, infact i have not touched my phone for 1 day 6 hours and 25 minutes and my battery dropped from 95% to 82%. My phone was fully charged (didn't go higher then 95%). I am very impressed by the results.
I changed 2 settings:
1. Automatic screen brightness.
2. Turn screen off after 30 seconds.

Wait a sec... that's not normal for me
Do you use 3G to connect to the internet? Never got more than 20 hours on 3G/HSDPA... without even using the phone!

Hello,
my Nexus S was updated automatically to version 4.0.4. I will tell you. My problem is with data. Now I can not open any WWW page in default viewer,Opera sometimes opens some pages but quite rare. I can not get any email in K9 Mail. Update of Google maps took several hours, unfinished, eaten all my battery! Sometimes I am without signal or with bad signal.
It is for sure problem with 4.0.4 because I have unlimited data. So, no FUP in this case.
I was satisfied with 2.3.6. How can I do downgrade without rooting etc. my phone ?

Check your APNs. But they should have come off the simcard when you updated.

Try find out what is hogging your battery/cpu. Download os monitor.
Or just flash a new rom to see if that helps. make a backup first

You need to install a better app. The Android built in power usage thing is about as much use as a chocolate teapot, and better battery stats isn't much better.
Try system panel from Play, you will need the paid version from here. Put it in monitoring mode and leave it for a few hours.
You will be able to see what is chewing CPU then, and that is invariably the thing that is causing the drain. It very rarely fails to assist me with diagnosis of an obscure drain issue.

Ok..just bought system panel app.will update about this crazy battery drain later..
Thanks thalamus..

Cool, it's well worth the couple of dollars.
I've used it pretty much constantly in monitoring mode since they were in beta when I had my desire. So, probably not far off a couple of years usage with me.
It doesn't eat battery either, because it polls when the device wakes up for another reason.
And the thing which really makes it good for me, it records usage of the system tasks, such as kernel threads, which can be massively handy in diagnosing an issue.

Solved by flashing latest adamG ROM..
Thanks adam and thalamus..haha..enjoyed my nexus s back...:thumbup:

Wifi Battery drain

Got a N5 a few days ago. I'm now running Cataclysm 4.4.1 and Franco Kernel r19.
While using Wifi and actively messaging using Whatsapp and FB Messenger I'm getting a battery drain of about 10% an hour.
Is this normal?

I've noticed that if you have WI-FI on ANDROID OS will have an enormous wake time, and most likely be one of the main contributors to your battery drain. If I stay strictly on LTE i get much better battery life.. strange.

If rebooting the router doesn't help, replacing it will.
It's probably something you are willing to live with, but it's most likely a flaky router. I've had cheap routers do it, expensive ones too.

Horrible Battery Life |-( (attached BBS log/SOT/+Screenshots)

I am sorry but.. after all the methods to save battery and even doing the fix in @timmaaa's thread about play services. Attached is what I am getting. Phone is new, but its been two cycles. Its stock CM11s, what it came with, it is rooted. No custom kernels. The brightness has been on auto mostly and when not thee, its at minimum. Cause auto at night is a bit bright.
I was expecting Galaxy Note like performance with that battery but this is worse than my 2yr old Galaxy S4

Oh sorry, you used a theme. By the way did you tried Greenify? I hibernated many apps, just leaving essential apps for it to run only, such as keyboard and launcher. All other like Facebook, Messenger, WhatsApp etc are hibernated.

Yup, have greenify with the donate addon. :/

Maybe you should try clean flash again. Emm maybe.

You should try to flash custom ROMs, I actually had the same issue you're facing with stock 11s.
Now i'm using SlimKat and the battery life is way better. Maybe you can try other custom ROMs such as PA 4.5 Stable, Mahdi ROM.

Quick question RE battery life + 5.0.2

When I tried 5.0 and 5.0.1 ROMs I had severe battery drain problems, so I went back to 4.4.4
I don't have time to waste flashing a ROM which hasn't solved the battery life issue which many (not all, I know, but MANY) people have encountered in Lollipop.
My question is this: NOT referring to your own personal setup, but regarding the N5 community as a whole - is there still a battery life problem prevalent on 5.0.2 ROMs for lots of people?
A simple yes or no will suffice. Thank you.

No. There never has been even on the L preview releases
Also there is no 5.0.2 for our device

Yes, there are definitely battery drain issues. I am not too sure it's related to the ROMs themselves but rather the radio. I have tried all Lollipop radios with a very basic set up on both stock ROMs and Cyanogenmod. At some point, I will get idle drain in the region of 2-4% an hour - way higher than I would expect.
There are no wake-locks - the device seems to sleep well - it's just idle drain is horrible. Go back to the radio from 4.4.2 and the drain ceases.
If one more person points to the Battery Life Q&A thread I might swear.

is it possible to use that radio with 5.0.1/2?
also:
fastboot flash radio radio.img is the right way to flash this, right?

Yes, I've not had any compatibility issues with any radio/ROM combo thus far. You can grab the radio image from the within stock factory images here https://developers.google.com/android/nexus/images or go straight to the radio (in both img and flashable zip format) here http://downloads.codefi.re/autoprime/LG/Nexus_5/Modems
For ref, KOT49E is the one I use. Technically this is 4.4.1 but 4.4.2 shared the same one.

The KRT16M the 4.4.2? If so i have a flashable zip if you want it

Radios are device-specific and rom-agnostic. You can flash any N5 radio with any rom.

Is it confirmed that the battery life using the old radio is better?

There is no confirmation.
There are too many variables, the biggest being location....
What's better for one can be completely different for another.
Test several for your usage and location. You may also find little or no difference as well
If you are still getting 'drain', narrow down the issue by logic: work out what is actually using the battery, they don't drain by themselves. Apply this thinking to any device

I believe my issue is poor signal at home on my desk causing battery drain overnight. By flashing an older version of radio will this improve my battery life in anyway?

There is no such "drain" in Lollipop. People just have wakelock issues with their own setup, the same as on KK or any version of Android. They simply put the blame on Lollipop and say there is nothing wrong with their wakelock issues.

It's a little narrow-minded to rule out all issues based on personal experience. My device, with current set up, sleeps like a baby. I don't use location services nor social apps like Facebook. My signal strength is fine.
On a Lollipop radio, idle drain after 1 or 2 days uptime will increase to around 4% an hour. On the radio from 4.4.2, my uptime can be a week or two and idle remains at about 1% an hour, everything else being equal.
Radios don't cause wakelocks, enable location services or install Facebook.
I do agree with one thing though - it's not Lollipop itself causing the battery issues. Some problem is deeper than that.

Radio's are an entire different story.
Different ones work better for different people.
Nor are they Android version related - there is no "Lollipop radio", its just a radio version that will work with any version of Android, and was the latest one so it was packaged with the latest factory images. Again, nothing to do with Lollipop

Cool. That's why I said "it's not Lollipop itself causing the battery issues".

Lethargy I disagree mainly because there are a few bugs in Lollipop that need work to make it a bit more stable. They have pushed the fixes into AOSP for the ones that have been found but it seems like custom ROMs on Lollipop or a majorly tweaked stock ROM do better.
A lot of it too I think is how poor Google Play Services is with battery. I feel like I have to jump through hoops just to get Google Play Services to behave.
