Well I don't no where to start really as I know I will get told off for making a new thread about battery life!

But this is hopefully some help for people out there that are trying to get a decent ROM and kernel to improve your battery life, well mine has really improved since flashing my Samsung GS2 with Lite'ning ROM 6.1 and flashing the kernel with SpeedMOD T-40.

I have spent lots of hours reading forums about battery life, I think I have tried everything known to man about this phone, somethings worked well somethings didn't, I wanted to get a decent battery life with out sacrificing any features I love about my phone!

When I got into rooting, about 2 months ago I was a n00b, but I stuck to it and learnt a lot each day, it's not easy and you can't expect someone to tell you how to do it, you have to read up about it like everyone else!

But anyway back to why I've created a new thread, well after installing Lite'ning ROM 6.1 at the beginning of the week which I really like as it keeps the Samsung software, I've used TB Pro to freeze the Hubs as I don't use them, the battery life wasn't what I thought, in fact I think I got a better battery life with the stock rom unrooted :(

I did some researching and found that the kernel can make a difference to (I'm still learning) so after reading some forums I learnt that speedmod kernel worked well with Lite'ning ROM, as It was just the kernel that came with the ROM, ninphetamine 2.0.5, so I flashed the kernel last night with Odin and within minutes I was back up and running.

I then charged the phone 100% and then use a battery calibrator app to wipe battery stats, I then did a basic test which I previously did before, I went to sleep with a fully charged phone, I left everything on: WIFI, mobile data network and sync on set my alarm clock and went to sleep (p.s I checked a few websites so battery actually went down to 98%)

8 hours later I woke up checked my phone to see what % it was left one, previously on stock ROM with same set up my phone would be on 65% due to the Android OS bug running high! This time it was on 91%, so that's less than 1% drain an hour! Happy or what!

I know some people might not say this was a actual battery test but to me it is and I can see a big difference, funny thing is the AOS was showin 35% in batt stats, which is strange!

Now as I write this at 1pm my phone has been on for 14hrs and I'm still at 75%, yes I know the first 8 hrs was in standbye, but I've had a lot of notifications come through from G+ this morning and I'm pretty happy with what I have got set up now, without compromise as well!

I will upload a screen shot later if any wants to see when my battery stats when its down to 1% etc

I hope his helps some people out there, but I wanted to keep it simple for some as I was once a n00b (might still be) :D
[Galaxy S II General] ephraim:
Better change your title.. when i first saw it i thought you are asking how to have a good battery life.. just a suggestion :)
[Galaxy S II General] maverick1103:
Just done, thanks for that :)
[Galaxy S II General] kreoXDA:
"Want good battery life!!!" - I believe the OP is ordering the reader to demand better battery life. I agree with the OP. Let's start "Occupy Samsung" movement.
[Galaxy S II General] norbu23:
thanks for this thread. i will definitely try it later after some playing around with CM7
[Galaxy S II General] ephraim:
@Maverik: Np dude.. glad to help

@Kreo: basing in OP's statement and the last part of it, he is stating how to get a better battery life instead of demanding for it..
[Galaxy S II General] chiefroastbeef:
Op, do you have auto sync on?
[Galaxy S II General] maverick1103:
No worries, I thought that if it helped me its going to help more ppl.

What's CM7 like, you trying the stable or the nightly?
[Galaxy S II General] maverick1103:
Yes I do and background data.
[Galaxy S II General] maverick1103:
I'm still relatively new to posting, but thanks again :)
[Galaxy S II General] norbu23:
I am the stable. its snappy and i liked the different look and feel with other roms that i hv tried such as litening, villain, batista and stock.

Today i installed setcpu and will see how the battery will perform.
[Galaxy S II General] maverick1103:
Cool, I did try CM7 but it was a nightley, build 68 I think, if they had brought the stable version out a week earlier I would be on that now, but I hear there are still bugs?

At least with Lite'ning its completely stable plus I like the look of the neon blue effect :)

My battery is on 64% now, I think I can go 2 days with this now :)
[Galaxy S II General] funtoosh:
I'm on CM 7.1 Stable now and now even after 2 days i still have almost 40% battery left out, though on stock i never got more then 1 days
[Galaxy S II General] maverick1103:
That's not bad, which Kernel are you using, the default one?

I have 5% left and going to screen shot it at 1% to show ppl what they can get, bearing in mind I could get max 12hrs out of it before!

1 day 9 hrs so far brilliant if you ask me! :)
[Galaxy S II General] funtoosh:
I first rooted it with superoneclick and it downloaded odin and flashed some insecure kernel first and then rooted it

Then i just installed CM 7.1 with Rom Manager, not sure which kernel is it
[Galaxy S II General] Matriak31:
if you are gonna try cm7 try the latest nightly build....thats pretty more stable than the "stable" version...i think build 83 is out today and that will have pretty much more bug fixes and i hope they can get that browser lag fixed and thats pretty done deal for me to switch over to that completely
[Galaxy S II General] maverick1103:
If you installed with ROM manager that will be the generic one that comes with it, check in about phone its second from bottom.
[Galaxy S II General] maverick1103:
I can't keep up with the nightleys plus when I tried build 68 I think it was, camera didn't work at all. Is the latest much better?

Also which Android version is it based on?
[Galaxy S II General] maverick1103:
Happy!

So as promised here are screen shots of my phone running at 1%, I forgot to screen shot CPU spy as well (sorry) but I can say that with this set up I am really happy, as I cannot remember when with general use I have managed to get over a day with out charging my phone, iPhone 4 included!

If there is a better set up out there with a newer ROM I would be interested as this is based on 2.3.4 tho Google Talk video works so I'm happy :D
[Galaxy S II General] Matriak31:
man that os is very high....but you still managed to get a day out of it so not bad work buddy..

nightly there is a new one coming out today version 83...still few bugs they need to sort out but once that is done il be on there...that firmware is based on 2.3.7.

im using speedmod latest kernel..it does not support bln or bootlogo but i would sacrifice all that for a decent battery life which i am getting....so far 5 and half hours past and im down to 75% and 2hours screen on time....not bad i think
[Galaxy S II General] maverick1103:
I know, I couldn't believe my battery has lasted with the AOS bug like that, really strange!

Yes Speedmod looks by far the best kernel around, do you know if it works with CM7? That looks pretty good 75% with 2 hours screen on!

I do want CM7 but will only jump across when there is a decent stable version, I love Vanilla Android! :D
[Galaxy S II General] norbu23:
@maverick :

i hv jumped ship to follow your config. i just love flashing roms :)

lets see how it goes with mine. as where i am (indonesia) signal strength is not very good. a few years back a nokia lasted 1 day here, while the same phone lasted more than 2 days when i travelled to singapore.
[Galaxy S II General] :
i dont know if that would work with cm7 mate.. i have a kernel that is pretty decent and fixed the aos bug kept it down to 5% throughout a whole day and 3 hours and only 9 minutes time on....

but speedmod is pretty decent buddy..but you got to try it out a few days before you can properly judge it
[Galaxy S II General] maverick1103:
Cool I hope it works well for you, worked great for me, I'm still in shock that my batt life has increased so much! :)
[Galaxy S II General] maverick1103:
I'll wait until most bugs are fixed and I'll no doubt have ago!

Have u tried any other ROMs that you could recommend?
[Galaxy S II General] fiestec:
I'm sorry but, you started a thread because you are getting 1day 9hrs battery life?

I get 2 days easy since getting juice defender. When I sleep it uses about 5% battery over 10 hours.
[Galaxy S II General] maverick1103:
I don't use JD, the reason why I started it was I know there are people having issues and I simply wanted to help that all, what have you done to contribute excatly??
[Galaxy S II General] :
sometimes when people say they get about 3 days battery life most of the time the phone is idle....now i can vouch that i used my phone very heavely and it lasted me about 25 hours and with 5hours screen on time....people who say 2 days or 3 the most i bet screen on time they get is about 3.......so i take most of the replies with a pinch of salt....if i see proof then i eat my ninja sword:D
[Galaxy S II General] maverick1103:
Indeed! :)
[Galaxy S II General] fiestec:
Recommended juice defender :-) try it. I'm on litening rom also with ninpo kernel. I was doubtful as to how it could make a difference but it really does work.
[Galaxy S II General] King Shady:
What do you keep your brightness at? Mines at 50% and I have the official 2000mah battery and I can get like 4.5 hours screen time.
[Galaxy S II General] :
Will the real Slim Shady please stand up, please stand up? :D:Dalways wanted to say that to you:D:D how you doing buddy?

the kernel that i used that time was made by hyperdroid team and i was pretty amazed by it..of course i used setcpu to get the best out of the battery also...i always underclock now about 800 max and 200 min and use a tad lower frequencies and have a screen off profile...wifi is on sleep when screen is off...brightness i leave mine at automatic sometimes i put it down to the lowest...depends on when im out really and then adjust the brightness...the most i would get out of my battery is a day and a half...but i get good use out of it to be honest buddy and thats with any kernel i use..the min that i ever got screen on time from a battery was 4 hours max and that was in about 13 hours usage
[Galaxy S II General] norbu23:
Mave, do you use setcpu to achieve it? also do you freeze some unused apps?
[Galaxy S II General] maverick1103:
No I don't have set CPU running, I will in a few days put it in to see what else I can get.

Ive freezed just the samsung hubs only as don't use them.
[Galaxy S II General] ujwols:
+1 for Juice Defender.. Battery drain during night 12 am - 7am is just 2%..during night it disables wifi. ..rest of the time I have Nitrodesk, IM+, Viber,Gmail, Background and Auto Sync etc on all the time.. I am on KI3
[Galaxy S II General] norbu23:
my take

My screenshot using same set up. I dont know if this is already good or not.

Comments please...

PS : How do i calculate my drain % ?

View attachment 752142
[Galaxy S II General] maverick1103:
It looks similar to mine tbh.

I would say though you need to get rid of Advanced Task Manger, the Samsung stock Rom, which this custom ROM is based on, has its own pre-installed (hold home button)

Having 2 running could be a negative effect!

I noticed you Android OS and Android system is similar to mine, when I first installed mine it was running at about 2%, but its shot up recently.

I would install CPUspy from AM and keep an eye on your clock speeds to see if your phone is running high for no reason.

But after almost a week I'm getting double my original battery life, so I'm happy!

I'm wanting to run CM7.1 on my SGS2 but there are two programs that I use basically on a daily basis that are part of the stock samsung package.

The Alarm with stopwatch and timer integrated, esp with smart alarm and snooze.

The Dialer with smart dial and gestures to text or call, I'm surprised that CM7.1 doesn't have a smart dialer.

If anyone has installable APKs for these two samsung apps I'd be greatful!

nice work!

with this, i may let the MIUI team to made real miui for us!

thanks and help solve the problem!

---------- Post added at 09:43 PM ---------- Previous post was at 09:22 PM ----------

help！！！！！！

why i flashed but just reboot on FXP logo？
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] bheremans:
Did you flash the kernel and the rom ? The rom wil noot boot without the provided kernel in the boot.img. The provided kernel will not boot freexperia cm7.

Also don't forget to reset to defaults (clear data / clear cache / clear dalvik cache)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] xutienan9520:
so..... the kernel is provider in CM7 from FXP?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] bheremans:
The kernel I provided it build from the freexperia git. But built with other options to match the prelink map for the rom.

I provided a kernel witch is built for normal prelink map.

Standard freexperia kernel is built to use 2G prelink map.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] xutienan9520:
so....there is no boot.img in this miui, and is the kernel you said is the same kernel in package of FXP041 CM7(with gapps)? or the boot.img in FXP CM7 ROm? or the boot.img from CM7 in CM website.....

maybe you can just put the kernel on, and the clear instructor

thanks
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] bheremans:
My mistake, I uploaded the wrong zip file.

Uploaded new zipfile with boot.img and rom. If you already have flashed the previous zip file with cmrecovery, then you just have to flash the boot.img with fastboot now.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] xutienan9520:
thank you！

i will flash the whole thing again, to have the best state!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] XperiaPlayer:
Hi,

The zip has been deleted from hotfile?

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] bheremans:
Added some screenshots
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] punkmonkey1984:
Would this work on the Xperia Arc? because of of the different screen size ?

Also great progress on this, i do like Miui so im happy to see someone with the know how getting this off the ground.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] XperiaPlayer:
Punk, it wouldn't work on the Xperia Arc unless someone ported it like I am doing for the Xperia Play. You have to recompile the Cyanogen Mod kernel with some specific config changes, then combine that with the MIUI.US version for the Desire S and then copy over some files.etc to get a UPDATE.zip. You then flash the kernel and that and hope for the best. If I can get it to work on the Xperia Play, bheremans can get it work on the Xperia Neo, then it is only a matter of time before someone will port it to the Arc.

Note that camera, data.etc probably wont work yet unless we get some proper developers in here :P.

hi i think i know how to resolve the FlashLight issue refer to this post:

http://xdaforums.com/showthread.php?p=18247100#post18247100

u will basically need to change ramdisk to give correct permissions to flashlight sysfs interface

also u might want to contact luke1215 as he is currently making MiUI for X10

regards,

DooMLoRD
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] punkmonkey1984:
I know i was not very optimistic about it running on the Arc due to the facts you stated above, but in general the whole new Xperia line is heading in the right direction, which is good.

Im only know just starting to get my head around .xml files, id love to be able to test and build stuff, but i dont think i have the knowledge at the moment to contribute to anything useful.

Time to do some research i guess lol.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] xutienan9520:
At last i flashed it!!!!!!!

quite nice, i can use the theme from miui.

i post a thread to miui in China, so maybe we can get the real miui in few months
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] JasonStein:
Hi bro,

You have done a great job to Xperia family.I have working on it for few days porting miui to Xperia arc but I have no idea about the kernel.Since the fxp's cm kernel is not suitble to miui so can you tell me how to tweak the kernel.

I have linux environment and I have got the source code from cm.Just tell me how to tweak the kernel and I will be appreciate.

Thx

Best regards

Jason.

P.S You mean tweak this option

from kernel/arch/arm/configs/xxx_defconfig

arch/arm/mach-msm/include/mach/vmalloc.h

before building the kernel?

Can you tell me some detils about your change to the fxp's kernel?

I don't know how to change the prelink map from 2G/2G to 3G/1G

Thx again!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] bheremans:
Hi Doomlord,

I know pretty good where the problem with the data and camera is.

kernel and rom libs are compiled with normal prelink map.

But some libs are precompiled and are linked with 2G prelinkmap.

For example is I use the commando isPrelinked (in cm tools), you will see :

libmmgsdilib.so: not prelinked

libmmipl.so: not prelinked

libmmjpeg.so: not prelinked

libmm-omxcore.so: 0xa4000000

libm.so: 0xafb00000

libm.so is prelinked at : 0xafb00000

but the preopritary files you have to use for example

libril.so: 0x6e600000

prelink-linux-arm-2G.map

prelink-linux-arm.map

MIUI libs : normal prelink map

proprietary libs : 2G prelink map

Mixem them causes preblems the system expexts libril.so at 0xAE600000

Same problem for camera libs

We can't compile MIUI from source and we can't compile some SE libs from source (for now)

but if we could free up the 0x6E600000 and shift things like in the commit you pointed out in the xperia play topic things could work out maybe.

Although I thought I had data runing on standard cm7 rom compiled with normal prelink map. So maybe I forgot to replcace some files in MIUI rom and we can get data working without kernel changes..

I am a java developper and system admin so I can read code and change some stuff and compile, but I am certainly no kernel developper :-(

Just posting all this stuff so others can understand the problems and maybe help :-)

JasonStein, yes, also CONFIG_PAGE_OFFSET :

http://xdaforums.com/showpost.php?p=18386122&postcount=29

I din't change anything to the kernel souce, only the config options !!
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] bheremans:
Xperia Arc / ray / Neo all pretty much the same, the have same cpy, gpu, resolution, ...

http://www.xperiablog.net/comparison/

the all use the same kernel source as far I know, maybe some small config options in fxp_xxxxx_debconfig. I should be able to compile a kernel and rom pretty easy. Maybe I will try to do it later today.

[HTC Desire S] matthewsucks:
Hi guys, one of my friend has the sensation xe and it has beats audio, am I right? I'm curious about what is the difference between beats audio and normal audio. Anyone care to explain?
[HTC Desire S] Deleted member 2496007:
It's basically Dr. Dre's idea of what EQ settings you should have when some Beats Audio high performance equipment is plugged in. Your friends phone will detect the Beats headphones (somehow) and Beats Audio will apply a certain EQ.

There are a few ports being tested which will work with any headphones, although it remains to be seen if this is actually a benefit or a marketing gimmick. Forcing an EQ designed for a specific set of headphones may not have a desirable effect when pluggin in some cheap £20 Sony's!
[HTC Desire S] dan-fish:
Dr. Dre's idea of making money
[HTC Desire S] matthewsucks:
Oh. So if I can figure out the eq settings, I will get the effects of beats audio?
[HTC Desire S] ben_pyett:
Dr Dre's and HTC's idea of being down with the kids and making money at the same time!

+1

@wnp_79

The jury is still out on whether there is actually any real audio benefit with normal headphones, please fell free to correct me someone!
[HTC Desire S] Deleted member 2496007:
Yes it's not like beats audio means it has any special audio processing hardware. It is simply an EQ tailored to get the "best" sound out of a specific set of headphones. If you are not planning on using Beats headphones, then it is kinda redundant. I'm simply curious to see if this EQ is better than my custom one using PowerAmp.

I have yet to test it myself, but I would imagine that unless you are planning on splashing out £100+ on Beats headphones, you are best of sticking with using PowerAmp and it's awesome equaliser to tune the sound to best suit the headphones you already have. Much Cheaper! Since we are on the topic, I can highly recommend the a-Jays One. IMO you'll not get a better sound for £20! Plus the cable is truly tangle-free! I'd have been very happy with these had they cost me £60.
