Hi, since I'm using the latest DoomLord kernel, i've noticed more battery drain than the stock kernel.
does anyone have this issue?
i'm using the stock rom without overclock.
thank you!

I am experiencing the same, was running doom v10 before and it would consume 1% per 2-3 hours. With v11 it is 1-2% per hour. Have checked cpuspy and it is running 98% in deepsleep and battery history only show the usual cell standby as power consuming.
Have only been running v11 since yesterday but will probably go back to v10 due to the battery drain.

It's the same for me.
I flashed the stock kernel,until a new version of DoomLord kernel will be avaiable.
Does he know this issue?someone should let him know that
thank you..
why not post in the thread dedicated to the kernel, that way your issues may be addressed.

Because I haven't written 10 posts yet so I'm unable to post in developement's topic..
Yeah, I have this problem on My Xperia Ray since I use The Latest DooMKernel... The Kernel drain battery...
user NeoCream wrote about this issue in the doomkernel thread..
Hi all
i just changed my rom from PA 2.22 to xylon 006 and i think i am suffering from some battery drain issue but i am not very sure ...
first off when i was using PA i am able to get about 18 hours of battery with 3 hours of screen time ( about 100% - 10% ) on stock PA kernel by the way , while on xylon my battery life is11 hours and 30 minutes with 2 hours of screen time ( 100% - 0% ) on Trinity kernel 1420 - 384
( stock/ franco kernel creates a yellowish screen on my phone whereas trinity kernel fixes it ) i heard 4.2 have some issues with battery and i am not really complaining just trying to make sure , oh i just bough setcpu from playstore and i realized i can change the scheduler ( noop , deadline etc ) and some weird stuff called interactive , ondemand etc ..so should i meddle with it ? how should i tweak it to get maximum battery life?
While i am on Trinity on dark PA 4.1.2, I know the kernel has some problems for now with 4.2 so i suggest you try Franco and install Trickster MOD app from the play store. Its free.
When installed, just apply the Trinity colors in screen section. Voilà!
Or reflash Xylon twice then the kernel. This might not be the kernel fault. Could be one gapp sucking all the juice... have you installed spyCPU and better battery stats to see which app was running?

kays thanks for the great advice downloading the app now! still what is the difference between franco and trinity kernel?
Hi all,
I am proud to be a small silent part of this community and to see how much the Galaxy W has grown due to the collective work of our members. I feel like the phone has damn near doubled it's value now with all the custom ROMs, kernels, tweaks, etc, etc that have been implemented in such a short time. Really, I can't see how this phone could be any faster! That being said I feel their is a void in resources dedicated to focusing on battery life while still retaining acceptable speed.
Moving on to Kernel 3.X has really brought great features and speed to our phone, but at the cost of extreme battery loss. It's early on in it's development, so I think there is room for improvement. I have noticed that members are starting to complain about battery life and I for one agree that this is a problem. I wanted to open a forum where we could collect ideas here so our precious phones could ideally make it through the day (or at least a half of a day!).
Anyway, I hope this will be a good jumping off point for discussing. I only ask if members could refrain from the old, "Just change the battery!" unless the user is reporting the battery is more pregnant then a Kardashian sporting twins.

I've had some success using conservative + row.
I'm really hoping to find a kernel that has more optimized conservative governors. Anyone have any tweaked conservative governor experience? I was looking at Scary or Lion heart, etc?
Btw I'm on RC 6 + Chronos kernel.

I'm going to try Governor: Conservative. Is it better than SmartassV2? Anyway, I'm going to find out, just finishing the charge to 100%. I'm gonna test on CM10 Alpha 6 + Athena Kernel. Will report back after draining.
Okey bro, im using smartassv2 with athena on cm10. I'll post my observation here.

I'd love to get a CM9 or CM10 RC7 with 2.6 kernel along with a kernel 3.0 version for people who loves kernel 3.0
I am not asking to develop 2.6 kernel further. Previous 2.6 kernel is very good, but we need a ROM (base updated/sources updated) which can support 2.6 kernel fully. 2.6 Kernel was giving me much better battery life compared to kernel 3.
i tried flashing respective 2.6 kernels on CM9 and CM10 RC6. It seems to work fine but if i plug the usb cable to pc then all memory cards get unmounted. ie.. i can't copy files to phone or vice verse. I hope arco gives us a updated source for 2.6 kernel with RC7 release..
My suggestions for better battery life:
1. First thing first: make sure your battery is not dying; if it's bulging, replace it immediately.
2. Use a kernel that's undervolt-able. I use ICS, and Yoon.Kernel is perfect for me.
2a. Then, undervolt your phone. The Incredicontrol app is usually compatible with the method used by your kernel. Or, read the kernel's thread to find out which app to use.
3. Use Greenify (app) to 'hibernate' apps you don't need to run in the background at all times.
4. If you have the money (and can purchase apps via the Play), purchase "Autostarter" and disable apps' starting points. You should focus on the "After Startup" and "Connection Changed" events.
5. Every now and then, while the phone is on, turn off all data connection (wifi or 2G/3G), turn off sync, and let your phone charge to 100% *and* keep charging for awhile (trickle charging, 1-2 hours should be enough), then let the battery drain until your phone shuts down (by using it normally). Let the phone cool down, plug it into the charger, and power it on, and let it charge until 100% again.
6. Use BetterBatteryStats regularly to find apps consuming too much power and/or holding wakelocks too often; complain to the app maker, and replace it if the maker won't/can't change it.
7. Remember to turn off wifi and/or use 2G only mode when you're no longer using them.

Pep, with full respect to your suggestions that are legit, but this can´t fix the battery drain issue CM9 is having with it´s new 3.X kernel.
They all will reduce the battery drain of course,but wont bring it down to the level you will reach with 2.6 kernel.
I´m still not sure what exactly is causing this, but in my case it´s for sure not my batteries nor other apps causing this.
As I already posted in the Bug report threat, I now flashed RC6 by going totally pristine. Formated both SD Cards and whiped everything, just installed BatteryMonitorWidget to control the battery drain. It´s twice as hight in DeepSleep compared to RC2 and RC3 with it´s old 2.6 kernel.
So first of all we need to narrow down what exactly is causing this.
Therefore I suggest to install first the BatteryMonitorWidget to comapare our results and to share the settings whe have changed after installing RC6 the pristine way.
First my configuration:
1. SDCards swapped
2. Dithering disabled
3. 16-bit Transparency enabled
4. Freeing up resurces enabled
5. Kernel sample Merging enabled
6. Zram disabled
7. default governor and scheduler
8. Syncing Accounts disabled
9. Updates and notifications in GooglePlay disabled
10. Wlan and MobileData disabled
11. Baseband XXLMB
My results with 2.6 Kernel are:
~16mA at daytime in DeepSleep
~ 5-8mA at night in DeepSleep
with kernel 3.x
constantly ~35 - 50mA in DeepSleep
and I checked it´s really in DeepSleep Mode.
So it looks like the radio is consuming more power while keeping the phone connected with the radiostation while the phone is in DeepSleep.
but....
I once also tested hadi´s 1.6 yoon Kernel with RC2, which is basing on Arcos RC2 kernel. By using the Ondemand govarnor in his kernel to compare the battery consumprion against Arcos Ondemand governor, hadis Ondemand governor also comsumed more than Arcos Ondemand Governor. With his OndemandX givernor the consumption was pretty much the same like with Arcos Ondemand.
So maybe it´s also something that changed in Arcos ondemand governor in 3.x kernel.

Oh I see there are several apps out now using the same name.
I´m using this BatteryMonitor Widget from 3C.
So when using it:
1. Do not recalibrate the battery as it will otherwise need much more time to show you accurate readings.
2. The App needs at least one or two charging cycles to recalibrate itself (not the battery) as it needs to determinate the exact capacity of your battery.

Hm well I´m used to recharge my battery every 3 to 5 days because it´s most of time in DeepSleep Mode. I´m just doing calls and surf the net in my breaks at work. So only turning on MobileData if it´s needed. At home I´m having my PC for surfing the net, so MobileData and WLAN is disabled as well.
With RC4 my battery drain was so high it even wouldn´t last as long till I´m back home from work. With RC6 i think it would last at least 12 to 18 hours, but it´s still a huge difference compared to the RC´s with it´s 2.6 Kernel.
Agree with you about using such apps like Task Killer or scripts like V6 Supercharger. They all need extra CPU time to do their jobs and often are causing more problems than they are solving.The Android OS can manage such things better itself and terminate unneeded services itself too.

Additionally you can use BetterBatteryStats in case your phone is keeping a long time active to see what is causing this. It´s free for XDA members.

I can testify to this, my BBS shows the phone going into deep sleep normally but the drain with data on is immense even in deep sleep. Your initial findings already point to the most likely source of the problem. Given the varying opinions on this(some say it's fine I others don't agree), is it possible we have the same device but different hardware revisions, some of which are much more power-friendly than others? Because for the life of me I couldn't NEVER anything more than a day from kernel 3.x(CM10) but some people claim they could get upto 3-4 days on light use!
Sent from my Wonder powered by CM10
I don´t think it has something to do with different hardware revisions, else it wouldn´t matter which kernel is in use. But it does.
There is for sure something strange going on. I´ve additionally installed BetterBatteryStats and now the phone started keeping very often in awake mode. Not sure this has something to do with this app, because it didn´t happen when I had it installed on an older CM9 release.
However I can´t find any suspicious processes that are causing this. But to be sure I will have to go back to RC2 to compare with.
So here my results:
Within of 5 hours it keept Awake for 25 minutes.
BBS also says NO Data Connection and No or Unknown SIgnal during that time
But I´m sure it was connected to the radiostation and made a short testcall.
About wakelocks:
KernelWakelocks:
"mmc0_detect" 4m 32s
"DPRAM" 3m 11s
"alarm_rtc" 2m 21s
"PowerManagerService" 1m 36s
"radio-interface" 1m 10s
"alarm" 36s
"mmc1_detect" 13s
Partial Wakelocks:
AlarmManager 44s 997 Counts
GSM 20s 4 Counts
ActivityManager-Launch 18s 104 Counts
sleep_broadcast 4s 23 Counts
RILJ 2s 146 Counts
*backup* 1s 109 Counts
NotificationService 1s 113 Counts
Ok I´m back to RC2 and am having some results from BBS to compare with.
After fully charging the battery I unplugged the phone and left it over night at the same place I´m always leaving. So the conditions were the same like with RC6, though in RC6 there were no apps exept BatteryMonitorWidget and BetterBattery Stats installed.
To make it short the results are nearly identical. Even the Awake time is almost identical in a period of 5 hours.
There is also the No or unknown Signal entry for the whole time. So I guess this is due to the MobileData being disabled.
But what I´m missing in RC2 is "mmc0_detect" and "mmc1_detect" in the Kernel Wakelocks. They are not showing up there.
So now we need some other results to compare with my results.
Been using this phone for 1 and half year now..is it normal to have a battery life of 5 hours with 3G on? Currently using cm10
I think the 3.0 kernel really makes a big difference in a negative way in regards to the battery life.
To fight against this, I have used the following settings for some success:
Conservative + Row... still very fluid with Yoon Chronos
245 - 1024 MHz
Screen off after 30 secs
Under volt
Its much better than before, but still I would like more battery life. Probably 8 hours with heavy use up to 16 hours lite.
Sent from my GT-I8150 using xda app-developers app
Agree on that. I tried now RC6 together with hadis chronos kernel and the consumption is the same like with Arcos 3.x kernel.
The "mmc0_detect" and "mmc1_detect" entries also appear with hadis chronos kernel. Not sure they are responsible for it, but they didn´t appear with 2.6 kernel.
So what I can say for sure it´s not the governor but something else in the 3.x kernel and so far these mmc detect entries are under suspicion.
First of all, sorry for not testing against the two kernels; there's a major project going on in my office, and I totally can't risk to be offline... plus with the random times I'll receive calls, the battery usage might be skewed...

I did some Google search and arrived at the following thread:
http://forum.xda-developers.com/showthread.php?t=1827676
scroll down to the second post. The OP of that thread noticed that mmcX_detect will utilize a lot of wakelocks if the SD Card is defective.
Since the battery drain issue with kernel 3.0 does not seem to happen to everyone, could people experiencing such drain try the experiments without an SD Card being installed?
Sent from my GT-I8150 using xda app-developers app
No problem pep. I need my phone too during the week, so only can do some tests at the weekend.
So to narrow down this problem we need to know how it works without a SD Card installed and if all who are having this issue are having the SD Cards swapped.

Please ignore the mobile network signal bar, every version of Cyanogenmod 10 I've used has the same problem where it stops logging data after about 10 - 15 hours, but my phone does pretty much always have at least 2 bars of signal where I live and work (split about 60/40 between 2G & 3G/HSDPA)

The best battery saving rom is CM9 with the older 2.6.35 kernel. So for example Arcos CM9 RC2 or RC3, the older Slimbeam ROM or this mentioned SmoothieICS. (The other two ones are just modified and themed CM9 RC2 or RC3) For even better results you need an undervolting 2.6.35 Kernel.
My battery for example lasts 3-5 days with CM9 RC2 and Arcos stock kernel. With my personal uv kernel it lasts even more.

Sure. Just drop me your e-mail via PM and I will compile one with stock voltages you then can adjust with incredicontrol to your needs. It´s because my kernel is preset to extreme undervolting voltages and that might be to much undervolting for your cpu.
Btw Arcos kernel has also deep sleep implemented and all custom kernels are basing on arcos kernel, so not only SmoothieICS is going into deepsleep but all custom roms are doing it as well.

your awake time to screen on ratio suggests to me that your battery life could be far better than it currently is! download WLD or wakelock detector and see what is keeping your phone awake so frequently =). Then u can get greenify to hibernate the app when u r not actually using it =D

Unfortunately the two main culprits are K9 email and ebay, both of which are pretty important for me to have running and not in a hibernated state.
However, from the last charge on my phone I have got 2 days, 4 hours, 29 mins with 12% battery remaining - so could be worse I suppose
Thanks for the suggestion though :good:

Now I'm using EHNDROIDX 4.4.2 and I think it's good!
Hello,so what kernel you like to combine with PA? -Nexus 4
I've tryed few
Franco r203-i think is has a battery drain problem /no update till now...
Trinity-no gama controll(and that is pretty annoying for me)
faux-idk why i just dont like that kernel
matrix-ok battery but low fps in gaming(maybe im doing something wrong?)
hellscore-hmm idk how its now ....
I would love to try ElementalX but its only for N5
The "wish list"
-over 4 SOT in wi-fi(3g,bluetooth,nfc,data,gps-all OFF ,dont need them)
-has customizable color-gama
-low consumption over night
-NO low fps in games like Asphalt 8(can change pref with Per-App modes if need [low on daily apps and custom profiles for games])
Thats all
What do you recomand?A few pros/cons on the kernel.
Try hellscore b43
http://d-h.st/users/hellsgod/?fld_id=27672#files
hells-Core-b43-kk-t2.zip. Flash this file. Enjoy!
This kernel gives better battery life for any ROM. 100% results.
After a day of testing more kernel
My favorite for now are:
Trinity- 4cores on all time and combined with tkt for gamma
Hellscore b43 -its very cool ,i'm very curious how will perform over night the b44 version because the low frequency
This 2 i love the most
For what it's worth, I have no exceptional battery drain using Franco Kernel. I lose ~1% per hour with the screen off, and <0.5% per hour with the screen and radios off, which is as good as it get for this device, in my experience.
With normal usage and without disabling Location Services or radios, I tend to get 5 hours of screen-on-time; sometimes more.
So till now trinity and hellscore in 5% drain i get over 15 min of youtube playback but on franco r203 in 5% i get like 8-9
Edit:I've changed from 1,5 to 1 and now it's battery drain is much better ,like the other 2.
Lupus kernel. I was using the awful one that came with FreeXperia but that was crashing 20 times a day. Finally found Lupus and it hasn't crashed since. Battery lasts at least four times longer too which I didn't think was possible, and I haven't seen since using the stock ROM.
(Android has crashed once but that's because it's Android)
