Hi, I have been observing my battery usage for the last few days and have noticed this to be using a high percentage of my battery, it is listed under kernel wakelocks. I would like to know if anyone has this issue and if there is a solution to it.
Currently on trinity kernal, also had the issue on lean kernel and Franco's using akop rom

Hey guys
I'm experimenting with the Franco kernel (r89 currently) and I'm wondering if anyone has any info on whether one ROM or another is any more processor intensive than another and, if one is better, if anyone has any suggestions for battery friendly ROMs to run with Franco.
Cheers, Paul
GSM Galaxy Nexus
ROM - Cyanogen 9-20120312-NIGHTLY-maguro
Kernel - 3.0.8-franco.Kernel-nightly 89
Liquid gives me the most battery life.
And which AOKP? more details
Galaxy
Yeah, sorry, milestone 4, have you used it?

i cant comment on cm9, never tired it. im currently running milestone 4 and get great battery life. usually about 20 hours idle and 3 hours of screen to kill the stock battery. i dont have anything syncing except weather every 4 hours. No problems with kernel wakelocks.
Awesome, may try Milestone shortly. Is a kernel wakelock exactly what it sounds like, not waking from sleep?

a wakelock keeps your phone from going to sleep properly when you turn off the screen, ie still using your cpu and battery. check out this thread about wakelocks. http://forum.xda-developers.com/showthread.php?t=1462020
Will do, thanks for the info, learning more every day

For battery life check the 4.0.4 roms or liquidsmooth. better battery and performance too.

OP uses the GSM variant of the Galaxy Nexus. There are no 4.0.4 roms for the GSM Galaxy Nexus.

i m using gsm version too and i m running 4.0.4. There are 2 4.0.4 roms currently modaco and foxhound with aokp modifications.
i have no issues with cyanogenmod (4.0.3) and battery life, though i do run a custom kernel (fugumod's)
I use CM9/Franco-kernel and have better batterylife then stock (4.0.1) but I have also heard thet 4.0.4 should be better. I'm hoping we soon get the source for 4.0.4
I have typically had very good luck with my battery usage, and when I dont I can usually track the source and fix it, however, I am really battling with 4 hour battery life lately. Can anyone suggest a good kernel for this, or maybe some trouble tips.
Thanks in advance.
I'm using the faux kernel it came with and my battery life has been fine. What kernel are you using?
Sent from my Galaxy Nexus using xda app-developers app
Honestly, tried many kernels, such as Trinity, Popcorn, Franco and Faux, but I gotta say, battery life doesn't change too much. What you can do to improve it though, is to undervolt it. Or underclock it if you're ok with that. I also recommend you to use SetCPU to set profiles.
Try Jame Bond kernel.

Hi, guys
Im thinking about an issue that everyone is looking for the best kernel to chase for the lowest battery drain but i thought the main reason of it is SCREEN, I mean most of drain is from screen using right?
So i wonder if theres no many difference between each kernel at bettery drain?

i agree +1
I recently upgraded my E4GT to build FI03. Overall I find this release to be very stable but my battery is draining in around 4 hours. I see that the kernel is using up between 65%-70% of my battery. I'm fairly new to rooting and am wondering if there is a better kernel to use than the one I am using?
Currently my kernel is listed as:
3.0.15-1083465
[email protected] #3
SMP PREEMPT Mon Sep 3 20:27:53 KST 2012
I am running stock ROM and stock Recovery, but the phone is rooted with FI03 build IMM761.FI03.
If there is not another kernel to flash, is there something I can do to prevent the battery from draining so quick? I don't overly use the phone that much, but even if I did I should get more than 4 hours off of the battery before I have to plug it into a charger.
Thank you in advance!
Get the Universe ROM it has the cpu sleeper it really helps

I'm new to custom ROM's will installing a custom ROM delete apps and data or will everything remain as is? I've got no problem trying them out what so ever if it will help my battery life out.
Your kernel is using that much because of a wakelock. You need to find the app thats causing your phone not to deepsleep. Try betterbatterystats and cpu spy. Find the app thats is doing this and everything will be fine.

Use Agat Source kernel for Twiz

using better battery stats it appears as though wlan_wake and power management service are using almost 30% of the battery and i'm not familiar with CPU spy and exactly what I'm looking at but my phone is spending about 70-80% of the time in the 200MHz state.
as far as apps there doesn't seem to be anything out of the usual. Sometimes NetworkLocationLocator is around 10% but otherwise there's nothing else I see out of the norm.
I am on FI03 stock rooted and my kernel use is usually around 30% or less, like others have said there must be a wake lock issue.
It appears also as though com.Google.android.Location has 568 wakeups in 8 hours. I would imagine that's a gps issue.

FI27 should be getting pushed soon and I hear it has good battery life. *slightly off topic I know

Hey there!
I've been reading for a long time in this forum- mostly about increasing battery life!
I always thought my battery life is average but today I just have to share my battery stats with you and ask for advice- many people getting 3-4h screen on time, I roughly get 2h!!
I'm using xylon 011 custom rom with latest franco kernel (r344). Baseband is XXLH1 with corresponding RIL. I'm using no live wallpaper and just hd widgets (syncing weather every hour) and google play music widget. I have two mail accounts syncing every 3h, facebook off and maps no location service what so ever! I also uninstalled lightflow! Gps always disabled, wifi on as much as possible- rest of the time 3G.
Brightness on auto-default values!
Thanks for your help!
Check these battery stats!!

Bump- is it possible that I have to buy a new battery after one year?
Last franco's nightly(r344) as some problems,including huge idle battery drain. The only thing you can do is downgrade to r342 or change kernel or patiently wait for a fix. Me too using r344,in 5 hours my battery was expired! I'm waiting for a fix
Regards
Try using 007 kernel. I found I want to be the most effective for battery life

Thanks for this input but I recently bought franco's app for just too much to just switch kernels now ^^
I hope it is really the kernel that is the problem! This drain is so annoying- reverting to r342 now, posting back!
I have Franco's app too but I don't like the newer revisions and I really like the 007 kernel performance and battery life. Worth a shot no harm done

Faux123 kernel is by far the best and everyone neglects it. Try the mainline smartreflex version and use his app to tweak it for even better battery life.
Thanks I hope franco will fix the drain soon! If not I'll try 007 or so!

Zen is by far the smoothest and most battery friendly kernel I have tried in my Toroplus. With every other kernel, the battery drain graph would drop like a stone - it merely dips in small increments with Zen v14.1 (screen is on throughout the duration of the attached graph).
