[Q] CM7 + franco.kernel and battery life - Optimus One, P500, V General

I'm experiencing a satisfying battery usage with 6.5.7 (great rom, thanks Mik!), but I'm trying to have more battery life.
Franco said that going under 480Mhz for underclock is bad because you force the CPU going up and down too much and so you drain your battery.
I trust Franco (great kernel, thanks Franco!)
So I'm actually at 480-600 smoothass
Is still worth it using a SetCPU profile for "screen Off", and doing a 245-320 or it is better to set a fixed amount of Mhz to avoid CPU up and down?

AFAIK there is no need to install SetCPU because with smartass governer the phone automatically sleeps at a lower frequency. I read it a long time ago, so correct me if I'm wrong. Today afternoon I locked my phone and for another 6 hours I did not use it(was busy with work). The battery drain was 1%. No SetCPU installed. OC 768/480 smartass. Manage your background apps and auto-sync properly and you'll have great battery life for sure.

You're right, smartass has a sleep profile, so if you use a setcpu sleep profile along with it then it'll cause more drain. And frequencies 480 and below require the same voltage so lowering the sleep frequency to a insanely low 122 MHz will not help, and it will also cause your phone to lag when waking up.

Test new fk-gbs.v14f modification
Guys, if you are seeking for best battery, advise you to install franco -gbs.v14f modification.
I have been running mik's CM7 with kernels v 18 (default in package) then v19.1, 19.2, 19.3, 19.3 gbs.v14d modification and finally 19.3 gbs.v14f.
The last one gave me a really noticable enhancement of battery life.
I will provide screenshots soon (when my battery finally gets low

Here are the pics:
1.From the begining to the first time it was connected to usb (see the "charging" yellow line below) - v19.3 was installed. After yellow "chargin line" v19.3 bgs.v14d was running.
2. same cycle, after another "charge" line, v19.3 bgs.v14f was running
3. still same cycle, more time on v19.3 bgs.v14f
see than batt level began dropping very slowly after last update was intalled.
PS. I am running smoothass @480/600. 3G. Data during screen off - turned off. With "green power" I have set up data to turn on everyhour for 1 min.

Can I use v19.3 bgs.v14d in Gingerbread official rom?
If not, which kernel has best battery life in GB official?

No No...

No. All franco's kernels of v15,v16,v17,v18,v19 etc. are for OLD baseband. Therefore they cannot be used for official GB ROM with has new baseband.
See DEVELOPERS threads for kernels which specifically are made for NEW baseband; this should be clearly stated on the face of the thread.

I agree with this. I've been using franco kernel from v19.1 to 19.3 and gbs from 13a to 14f with CyanogenMMatt v1.1 and the last combination (CMMatt + gbs v14f CFS) is amazing. When sleeping, 3 hours only consumes 1% of battery. I even overslept while ebook reader is on, which kept the screen awake for 4 hours but the battery was only down by 10%. With other kernels that could get me down by at least 15%.

Kernels have nothing to do with baseband.The thing is that official 2.3.3 and miks 6.6.x(OLD BASEBAND) are optimised to be used with 2.6.35 & and miks 6.5.x are optimised to be used with 2.6.32 kernels.Dont provide false info until u know the truth.

You had very good results with that kernel, I will try it soon!
Thanks for your suggestion.
I had improvement uninstalling SetCPU and using underclock at 480Mhz.
Since that Mik put his two cent's on ZRAM (http://forum.xda-developers.com/showpost.php?p=15011492&postcount=5889) I think it's better to uninstall it in order to improve battery life.
I'm going to use this dr.notor (Thanks! R.I.P.?) zip to uninstall ZRAM (http://forum.xda-developers.com/showthread.php?t=1207251).
I will let you know about the results...

Cm7 - horribly battery - i don't think its cm7

i'VE BEEN RUNNING CM7 for a month (about)
I update to the latest version and right now im on the KANGED version thats not OFFICIAL release but it is made by the dev.
Anyways...
Every day i wake up in the morning, from 100% my battery goes to about 90- 85% from using it then i go to school, phone in my pocket for about 7-8 hours.
It usually goes to 70% or 75% when i check soon as school is over.... but today.. it was at 32%!!?
My battery has been draining FAST this past week. IDK what's causing it, but i think its a app, but watchdog lite doesn't show anything at all.
Any tips at all guys?
- PLEASE DO NOT REPLY TELLING ME TO PUT IT ON AIRPLANE MODE WHILE IN MY POCKET- I GET TEXTS FROM MY BROTHER/MOM TELLING ME IF I HAVE TO WALK OR IF THEIR GOING TO PICK ME UP AND OTHER IMPORTANT INFO LIKE THAT-
Please help me out here.
I love CM7, and it's NEVER been this bad, but if it is because of CM7 then i have no choice but to go back to 2.2.1
EXTRA INFO:
I don't have a data plan so... my phone can't communicate with other servers and crap.
I keep wifi off, bluetooth off GPS off.
Maybe i'll have auto brightness on but thats it.
Check what profile are you using on setcpu? Also you might wanna check the signal while in you school.

I just slept for a hour. I lost 10% in that hour. WTF is this lol
try recalibrating the batter by using either root explorer or the terminal to delete /data/system/battstats.bin as sometimes CWM on cm7 for galaxy s doesn't delete it.
i have the same issues and tried everything..i dnt even have data plan to use internet and i keep my 2g on and my battery still drains like pipes in the sewers

try not using the battery claibrator app, and removing it from your phone and manually deleting the batterystats.bin file from /data/system and see if that helps your phone at all.
I also suggest getting CPUSpy from the market, and track what states your phone is in and for how long it is in certain states. if it's not going into the sleep state, then something is keeping the cpu active (possibly a governor setting).

That aint normal my friend, you should jump into another modem, regardless of what you're on. Maybe that helps and by all means, what kernel are you on?
I'm on the stock kernel... Should I visage and can you link me to more cm7 modems or atleast a good one that works good?

The stock one should be battery efficient but I honestly haven't really tried it out. Give r12 or r25 a shot from here. They've been great in every aspect to me. Just make sure you're not on kang 7.1 when flashing, it doesn't support that.
As for modems I'd suggest either KB5 or KB1. If you're on either one switch to the other, may help.
don't run phone on "performance" -- it's silly to run the cpu at top speed when the phone is just sitting doing nothing. Run it at "on demand" or "conservative" especially if it is OCed. Also set screen timeout at a minute or less. If you got the phone used, it's possible the battery is old. If you reboot it a lot and install roms and stuff you'll run the battery down fast.
Well..
Yesterday I did a cleaning of apps i never use and some i installed recently.
I guess that did the trick? I have no more problems came back from school and my battery's at 76%
@Abu, thanks for the tips. i don't want to get a different kernel and modem.. im on kanged 7.1 lol.
@Nazcalito
Fearing it was that i uninstalled SetCPU.
Should i re-get it and make it OnDemand?

don't use setcpu if you don't have to. the built int scaler for the kernel is actually much better than letting setcpu run in the background polling the cpu and system for changes.
if you're running a custom kernel, get voltage control, and with it you can UV, OC, under clock, and change scheduler.
And in Settings -> CM Settings -> Performance -> CPU Settings, you can control min frequency, max frequency, and governors.

Problems with battery drain... =s

hi guys,
i'm having some problems with the battery life of my LG P500 (with CM7 + Kernel v18.1).
i installed this custom rom because some people told me that it has the best perfomance. But what I see now is a bad battery drain...
what I have to do? Change the CM? The Kernel? Or what?
unfortunately, i accidentally deleted the backup file...
thanks!
After you install a custom rom you need to first wipe your battery stats from your recovery then you can also use battery calibration app also you need to give your phone some time to get used to the performance for the battery life to be accurate you can see this warning in a few roms and in francos kernel thread the performance is better and the battery life is better to issue also suggest turning off your 3g when not using it if you have a 2.3 rom then you can go to cyanogen mod settings if it has it and add it to your notification buttons my battery on medium to heavy use will last 24-36 hours where with stock rom maybe 10

well, i don't use 3G... i keep this turned off. ;D
so, this is the only thing that i can do? Wipe battery stats?
i did this right now... let see...
There's not much you can do that has actual effect on the battery life. Keep wifi & 3G off when u don't use them is usually the first advice. Unfortunately overclocking means that your battery will drain out very fast. Mine's on charge via USB-cable most of the day, and using wifi or playing games for 40 mins means at least -20% battery power.
i know about wifi and 3g... ;D
and what about custom roms and kernel? my cobination could be a problem? =\

CM7 (6.5.5) comes with franco's kernel, and as far as I know, that's the best one at the moment, so I don't think that is the problem either. it's just how this ROM is ... you're not the only one with the same problem lol
how many things are you running in the background?
I've had issues with a couple programs eating cpu in the background.
oh and brightness makes a large difference.
if you have missed message flasher running by either flashing the screen or vibration's that will also drain the battery fast.

if maps is running that is what is killing your battery .
if you want maps
get titanium backup and backup (or if you have paid freeze) the app and restore/unfreeze when you want to use it.
Yes Maps can drain the battery a lot lol
ps. you can see what is using your battery if you goto
settings ----> about ---> battery use
Lucky you can turn off 3g I'm on a provider that won't work unless I have it enabled -_- lol
My main reason for flashing a custom ROM is the ability to change permissions for each app that has been merged into CM and is part of mik's port. That combined with droidwall is a very important tool to battle the privacy violations with so many apps. That means that I didn't overclock, but I still saw an incredible battery drain on 6.5.5 + 18.1. Plus I was getting a weird log error with droidwall. I appreciate all the efforts on behalf of the developers, and I really hope to get a stable rom that would let me modify permissions of all apps with good battery life. Everything else is secondary.

Google maps will not drain battery until u have data enabled,same applies for other processes running in background.
And overclocking also doesnt drain battery faster as said on franko tweaks page.

False, read this about overclocking and battery, analyze the chart
And with google maps plus other similar apps running in the background, it will try to connect and find a connection therefore draining battery.
processes that only run in mine are:
google services (1process, google messaging service)
android keyboard ( dont tell me u dont know that )
pretty much those are necessary for your phone to be functional.

I got OC info from this page.
And abt maps,i have stated that it will not consume battery when data is NOT enabled.
Anyways thanks for those charts.
But as per my personal experience,OC doesnt drain battery faster
Use v18 CFS, not v18.1 .. i had the later and the battery drain was huge. Switch to 18, charge to 100%, wipe battery stats, use until completely discharged then charge again and see if that helps. OFC not even v18 can compete with the stock (or even mik's kernel) in terms of battery life, but if you want performance...
For me the best option was mik CM 6.5.5 and fk v17 cfs!! Definitely feels stable all the time!!
thank you, guys!
well... i really made a little mistake... the battery life improves with the fkv18 cfs. isn't a awful improvement, but is something.... =D
should i change to v17? =s
how i can see, CM 6.5.5 is the best option...
thanks!

Hm, i thought devs like andy and a couple other devs mentioned it before that g-maps & other similar apps will consume a %tage of batt. It's similar to bgsyncs. You can see for urself and log then block it with droidwall.
let's say:
you got every connection off (wifi, 3g off, only 2g for messages/sms otherwise none) > g-maps running > it will TRY to FIND a connection at a specific interval e.g. ~20min. > therefore consuming resources. I dunno about the latest versions of google trashes though (maps got offline support)
About oc'ing, yeah 122-480ish consumes the same BUT not if your phone is demanding more cpu to complete tasks, i.e @ 122 clocked it completes the tasks at a longer time than 320 wc is fast, just balance it if you are gaming or just using it for web browsing/sms/calls/music/minimal gaming like me( ~2.5 days atm im on 320/729 v18 bfs smartass & it's good enough).IIRC franco told this on his earlier pages on the kernel topic

Correct me if I'm wrong but for a 2.3.4 rom shouldn't you be using the BFS version of Franco Kernel? I believe that CFS is for Froyo roms (at least that's what Franco himself told me on a post a few weeks ago)

In your opinion. Best Kernel for Battery Life?

I've used ninphetamine 2.1.3+ and it used to drain my battery a fair bit. After having seen another user who said he was experiencing better battery life with ninphetamine 2.0.5. I flashed the older version and it turns out to be indeed better.
My idle drain rate is now 15-17mA using Battery Monitor widget.
So when put in picture. Drain rate is about 2% per hour with minimal usage. (Note 3g data was on)
Anyone else have a better kernel?
EDIT 1:
I've tried using SiyahKernel (KI3) and it seems that according to Battery Monitor widget the idle battery drain is 14-15ma. Seems to be much better. However, occasionally the touchscreen freezes and only the touch button works. But then again it could have been because I was using the KI3 kernel on a KH3 rom. Would report back after I finally get off my lazy ass and flash a KI3 rom
EDIT 2:
Got off my lazy ass finally. Flashed LeoMar 2.7.1 rom with SiyahKernel 1.7.8. Will report back after a while. Though I must say that for some reasons after the boot animation the phone turns black for quite a long time (1-4 Seconds) before the lockscreen appears. This did not happened with the default LeoMar 2.7.1 kernel. Will report back in 24 Hours.

Thanks sherlock. I posted my findings and was asking if anyone else had better. If it the time of the month of you. Stay off this forum.
Personally I find it very difficult to make meaningful comparisons, especially at idle.
Battery Monitor Widget gives estimates and not actual current drain. See this thread for some discussion: http://forum.xda-developers.com/showthread.php?t=1056486 but basically it's either not in Samsung's battery driver or the app is not reading the information. So you are comparing estimates and the margin for error might be pretty large.
When you flash new kernels you also need to recalibrate the battery. That also affects your battery drain estimates. (I've had Battery Monitor Widget tell me my battery is going up when its unplugged, so go figure.)
Battery life at idle is affected by so many factors. Maybe your signal strength is better one day than another. Or you got more emails or did more syncing. Or one app just happen to glitch and have a very long wakelock. If you get battery drain, you should be checking your partial wakelocks with BetterBatteryStats. Did you get more partial wakelocks when you were running Nin 2.1.3? Is it the kernel's fault or did you just have a misbehaving app?
I like experimenting with different kernels too, so my point is don't expect miracles when somebody says Kernel X gives amazing battery life compared to Kernel Y. Personally I think they are all about the same at idle, and the big differences are in your settings and your usage. If you wipe your phone, don't add any Google or Exchange accounts, and don't sync or download anything, your battery will last 3 or 4 days on idle no matter what kernel you use.
Stock rooted KI3 (cf-root) is the best for battery life for me, i also have constat 3800+ quadrant score (with top of 4109 as my screenshot in leomar 2.7 rom thread).
Also i have the phone a lot, but really a lot less hot while gaming or stressing it.
KI3 stock kernel and SiyahKernel are at the moment the best in battery life. Anything else is running on older sources and drain more.
The best for me is SpeedMod! Smooth and long life battery. There is something you can't do (bootanimation oc uv bln) but simply great!

best results for me: stock kernel reflashed after rooting, for that stock rom.
Bar none the way to go.
Stock Rooted KI3 does look good, am yet to test it though
Hmm. So seems like you guys are experiencing deliciously good battery life with KI3 kernel. I shall try it and report back with some numbers.
try siyah kernel. one of the fastest growing kernels IMO
For me is Ninphetamine 2.1.3 and now i'm trying SiyahKernel 1.7.7
My question is.. between stock ki3 and SiyahKernel 1.7.7 the difference is really small (barely notice it) or big?
I tend to not flash to much kernels since the very small chance to corrupt the efs folder (even if ofc i have my backup), so if it's only small improvement, i stay on the stock ki3, if it improves a lot, i prolly try it
I've been using the siyah kernel v1.7.7 and I've been experiencing a great battery life. I didn't use the stock kernel for long to make a comparison but I sugest you give siyah at least a try, since you can always go back to stock if you don't like ir.
Updated 1st post with my new findings.

batistaRom and ninp 2.0.5 great battery life for me...if you like i can post screenshots if anyone is using setcpu, depending on your kernel try and research in the kernel thread regarding frequencies that other users suggest and adjust yours accordingly...thats what i have done for mine and i could not be any more happier
Alright. I've finally got off my lazy ass and flashed a 2.3.5 rom (LeoMar if you must know) and am currently using siyah 1.7.8. Will report back within 24 hours after I've put the device through a day's use.
cf root KI3 stock kernel on RevolutionRom 2.7.1.
53 hours battery life 3 hours 19mins screen time wifi on 1/3 time, 4g on 2/3 time with facebook sync.

Pix or it didn't happen
Hi, I posted earlier saying that siyah 1.7.7 gave me good battery life. I tried now the cf root v4.2 KI3 and I had better results. Well, I'm someone that don't play many games, but I surf a lot and download a lot of stuff on wifi. I don't care much for overclocking so I think I'm going to stay wth KI3 cf root. For me they're both great for battery life, and maybe the other ones I have not tried are great also (speedmod, ragemod, ninphetamine...)
I think what happens with kernels, and this happens also with custom ROMs (and everything really, brands, etc..) is there is a lot of fanaticism. People like to choose one ROM and kernel and stick to them. They start to defend the kernels they use convincing themselves they're the best no matter what. That is in my opinion the reason because this kind of discussion turns meaningless. Well not that meaningless, at least it gives an idea of the kernels people are using, at least we know speedmod, ragemod, siyah, nimph, are all great kernels.
I'm not criticizing anyone, in fact, I'm just another example of the people I described.

[Script] Baterry Saving Under MiUi with Stock Kernel

This is previous post by nobodyAtall and assumed that many people forget it already.
http://forum.xda-developers.com/showthread.php?t=1061691
I tested it with my Build Own MIUI in 30sec from erenz1202 with lastest
Miui-1.10.28 for X10i luke1215 from Luke 1215 and his newest kernel X10i_MIUI-1.10.28_Luke1215-2.3.7.ftf. I
I did test it since 1.10.4 upto 1.10.18 - it works well no issue. For standby mode, I loose 7 - 10% for 10 hrs stand by. For moderate used, it can used almost second day early afternoon for completed zero discharged.
I am not trying with other mod kernel ie. Doom Kernel, it I am not sure that it work or not.
It is alternation for who is looking for bettery saving and long stand by. For usage operation, I can not confirm that it is saving, perhaps it is a little bit saving [better than nothing]
For people who is looking for Miui-1.10.28 for X10i luke1215 and newest kernel X10i_MIUI-1.10.28_Luke1215-2.3.7.ftf, please visit http://www.miui.com/thread-249796-1-1.html
Unfortunately, when I try Smartass2 govenor, it seems to be that it drained bettery so quick. Let me test it for a whaile.
Thanks for reminding people about this, however, a lot of devs already include UV directly in their rom and if they dont you can always use the setexperia app (free from the market) to change voltages yourself in a more user friendly way.

Keep it as alternation. Personally, I myself don't feel the saving under voltage setting setxperia much by comparing with x10uv.
Personally, I am using V003 and not trying with v002 or v001 that more under voltage. FYI before that I am on DooMKernel-v05a-FS-BootManager-v1.3 with undervoltage script from ThJap. It worked good. But x10uv 003 with lastest Luke 1215 kernel is better especialy for me.
Hopefully that it is alternation who is under stock kernel, if it's working for your device, it will gain more battery usage time.
25 hours and battery left 27% - not bad

Mini Pro - Android System Battery

Hello Guys
My Mini Pro(sk17) is rooted and i´m using MESA Kernel(Smartass V2), i´m on stock I.C.S
I noticed that Android System is about 40, 45% on battery drain.
I´ve read a lot of things, added some lines at build.prop, but no sucess... its still about 40. 45% of my battery drain.
I´m already using 2g, screen bright very low.
I remember i checked that before flashing MESA that the android system did not drained battery like this....
Is this normal? Is there anything i can do?
I dont use any task killer, my CPU is set to 134mhz to 896MHZ( so is underclocked!).
Any help?
Thank you
set max to 1017 min to 134 governor to interactive x and scheduler to cfq

Ok, i´ll give it a try!
Thanks!
I/O Scheduler has no effect on battery life.
The problem - ICS. In the ROM, there is a bug, after charging via AC(wall charger), phone's Android System uses a lot of battery. Why? It's a bug in the ROM, that we haven't found.
How to fix it? Restart after charging.
And there is already a topic about it. Use Search next time before making new topic.

Try setting your minimum CPU freq to 250MHz. It actually uses way less juice then 134MHz!
EDiT: regarding what someguyfromhell said.....
I've never experienced bigger batt drain when charged AC as opposed via USB?
I'll try to reproduce that effect though...
Hi again,
i tried that Someguyfromhell said and the same thing keeps going.... 45% of android system!!!!!!
any other advice?

Have you tried setting minimum freq to 250mhz, and changing CPU governor?
That should do it.
If not, try another kernel.

Dude,
Good sir, i kindly reccomend you should change from Man Eating Seals Of Antiquity (M.E.S.A.) and switch roms, experiment, play around, you will never get good results just by asking around, you need to figure out your own way of making battery last longer.
I miself am now trying out CM10 alpha for my Sk17i
Good luck

i agree with u my frnd...trying different kernals and roms you can come to which rom and kernal is stable according to you and which has the less battery drain..i suggest u experiment these things.. instead of asking others..
iam also tring Cm10 alpha now for my xmp sk17i.

OK I'm using my phone for 3 days without any charging. Maybe it's just because I don't turn on wifi/3g (I'm browsing only on my tablet).

yup..when wifi and 3g is off ul get more bat...
when it is turned off its around 1-1.5% battery drain/hr
Hi again.
I´ve changed the Kernel from mesa to another one i dont remember now, and now the batttery is working like a charm.
Changed the kernel and frequencies as iONEx said too.
Thank you very much!!!
Sergio.

Changing kernel, governor and frequencies, now my battery last charge was on sunday night, and still got plenty battery for today.
I use kamarush v2 kernel, and it is the best kernel for me.
I used v3, but it is not as good like v2.
Hope, the kernel will goes to higher level, like in X10mp
