I always have Google Talk set to disabled. I do not use Live Wallpapers. I use the GPS and the FB/Twitter syncing. Unless you are saying that in CM9 it inefficiently uses the battery because I had those on in the stock ROM. I turned off the Wifi sleep but I have not used Wifi on the device (that is a rare event for me... other than after installing a ROM to reload all my apps from the Market.)

The Processor setting was the only thing from this that I adjusted. The network was already set to GSM. I witnessed that issue when I first acquired the phone: the LTE was sapping battery juice like crazy. My battery life is more like LTE is on than its a matter of adjusting apps. So, if the Processor adjustment does not make a difference? Would someone recommend re-flashing the ROM?

dsixda or anyone... please tell me that you are planning on working from the Stock ROM as opposed to CM9 once it is released (last ETA was August) for this device?

(My big issue is that Gingerbread edits Contacts on the Google server different than ICS. So, I need ICS asap to resolve this.)
[Galaxy S II General] dsixda:
Well, there's your battery issue right there. This is not even an ICS issue or CM9 problem. It's a user configuration issue.

Why do you have GPS running if you don't use Navigation?? Your location is detected by the cell phone towers anyway, if you need it for location in Facebook or 4Square. GPS is a huge heat creator and battery drain.

If you have Twitter syncing every few minutes, your battery is going to run dry in a few hours. Same problem happened to me way back in Froyo. What's wrong with manually updating your feed and having twitter.com alert you by Gmail when someone sends you a mention or PM?
[Galaxy S II General] dsixda:
Wrong thread dude. Just pay $20 and deal with it. I think I just googled for prices but in the end eBay was cheapest.
[Galaxy S II General] dsixda:
I'm not happy with the last ROM, guys. Obviously those Google app issues were a problem, and I'm guessing someone fixed them soon after. I have synced up with the latest updates as of today and am building from scratch. I am also going to be including some newer versions of ICS system binaries.
[Galaxy S II General] dsixda:
Don't bother using the stock ICS ROM when it comes out. I used the Bell SGS2 I9100 update and it was very unstable and my battery life was much worse than it was on Bell's 2.3.3...

Your issue cannot be solved by any ROM unless you go to a new phone with a huge battery. Or if you set your max CPU speed to 500MHz ;-)
[Galaxy S II General] zz3ta:
Yea I have 0717 running, but whenever i try flashing gapp... it reboots automatically within recovery mode with no log, nothing.

Using 7zip to merge the two did the job though. Thanks for the help!

By the way dsixda, awesome job with the cm9 port!
[Galaxy S II General] jsr84:
I flashed the latest update a couple of hours ago with no issues, and its been running great.
[Galaxy S II General] dsixda:
Are you sure you downloaded a non-corrupted gapps?
[Galaxy S II General] dsixda:
Alright guys, I'm uploading the following ROM:

I haven't checkmarked the 'public' status option on this ROM yet, so if you don't see it in 30 minutes then assume I fell asleep and didn't make it public after uploading it.

I'll admit, I had trouble flashing this one due to strange issues (confirmed it by going to Advanced / Show log). I solved it by reflashing the July 17 ROM and then flashing this one again.

Please remember to flash Google Apps again afterwards! Looks like they still did not resolve this general CyanogenMod issue. Multiple people in the Galaxy S2 I9100 CM9 thread have been complaining about missing Google apps without looking at similiar previous posts in their thread.

I haven't updated my GitHub repository with the new files because my internet was down for a while, and now it's too late to go to my PC.
[Galaxy S II General] AllyKat:
Here is what I am saying. I use various features/apps that can be battery heavy but what I am saying is that my experience doing the same on Gingerbread (Bell Stock) was noticeably better. For example, I no longer can run my phone a full day without a mid-day charge. My battery efficiency on this ROM dropped my phone experience to 50%-70% of what it used to be when everyone stated there experience is better.

I forgot to mention. The process is running way hotter now.

My experience with this ROM thus far makes me know that MY usage maybe better with stock. The instabilities of CM9 may just be less compatible with my high usage of my cellphone. The only time I experienced this bad of battery life was in the first days of having this phone before turning off the LTE.

What I am asking is if re-flashing is recommended? I am asking if there were any ROM specific or CM9 specific features that default to being on that would drain battery that I might not thinking of adjusting?
[Galaxy S II General] markdexter:
Reflash is pointless by the sounds of things, go back to stock GB. If it's running hot, did you change any cpu settings? Did you install battery calibration app? When your phone reaches 100% unplug it does it instantly show 95-96%? Then plug charger in again keep doing this until you get a true 100% then use battery calibration app
[Galaxy S II General] dsixda:
Ok the July 18th ROM is now up. Please see details a few posts up (post #482).

Please wipe your cache and Dalvik cache before installing, as advised by Deafened. I have updated the instructions on post 1.
[Galaxy S II General] B.Moreira:
It would be nice if someone could make the sources for CM10 available for celoxhd, but I doubt that will happen soon :(
[Galaxy S II General] dsixda:
Nobody is working on CM10 for the celoxhd right now, so why would it be available?

CM10 source is already available, and you can use the device configuration for the AT&T Skyrocket as a base for celoxhd. Have fun getting camera and audio to work ;-)
[Galaxy S II General] B.Moreira:
Lol I don't even know how to make a rom or create it from source. I was kind of suggesting that when you feel this CM9 build is stable enough that you could try a CM10 build :p

P.s. The newest rom works good but the gapps are still broken and have to be installed after.
[Galaxy S II General] dsixda:
haha.. are you suggesting that I should be starting on CM10 and should release the source soon? I don't owe CM10 to anyone, I'm trying my best to get CM9 out the door and eventually as a CM9 nightly. I have less free time than most of those guys, I'm just doing as much as I can to get the most of my device. I can't afford to spend months on a hack-job that CM10 will be for a while to get stuff working.

Yes I know, it's not my fault, and I already mentioned it on the same page you replied:

http://xdaforums.com/showpost.php?p=28994677&postcount=482
[Galaxy S II General] B.Moreira:
Sorry, I'm not saying that you owe CM10 to anybody but I would like to know if you would even be interested in building it once you're done with this ROM.
[Galaxy S II General] markdexter:
Wow, see what happens dsixda. Some people are getting a bit spoilt and are wanting more. Instead of asking for more try it yourself, dsixda has provided more than enough information, I myself have just built this ROM using the help and posts from dsixda. Thank you.

Cm10 is nowhere near ready. If you purchase this device now you get. 2.3.6. Thanks to dsixda we now have 4.04. Now you want 4.1!!!!! Give it a rest mate
[Galaxy S II General] dsixda:
I thought I just answered your question when I said I can't afford to. I have already compounded an existing problem with my right wrist (that started with the ROM kitchen). My left wrist is now starting to have the same problem since I started on the CWM recovery image. I'm currently paying a couple hundred $$ a month getting treatment for a chronic neck problem that gets worse with sitting on a PC. Plus I need to spend more time with my daughter. Do you want me to continue being crazy? ;-) I definitely hope someone else comes along. In the meantime, be happy with what you have. :P
[Galaxy S II General] dsixda:
Wow, someone is actually using my Github files and building it? Awesome. Good for you, could you help me fix that Silly Faces effects problem? ;)
[Galaxy S II General] B.Moreira:
I am happy with what is have thanks to you :)
[Galaxy S II General] AllyKat:
I did not adjust any of the CPU settings.

No power drops normally... 1% at a time. Just extremely quick.

You are missing what I have stated. My usage is heavy. I am not looking to be told to reduce my usage. If everyone continues to "claim" that the custom ROM is more efficient with battery usage than it stands to reason that someone who uses the battery heavily should notice this. Instead its the opposite. Since loading this ROM. My screen will momentarily glitch showing what looks like you used to have on the TV when there was no signal. (Mind you, I am using the release from the 13th... updating to the 18th release right now.)

I have attempted to adjust the Processor settings to "Conservative" like recommended. The phone appears to have set itself back to "On Demand". I just set my phone to Airplane mode and even with no Apps running the processor is still operating at 1512 MHz. (Is this fast than stock? Is the processor being overclocked by this ROM?) Using the phone as demanding as I do an overclock would likely be where my battery drain is coming from.

Do not get me wrong: I love the fact that this ROM exists! I am just trying to figure out why on now a second phone that every device I have used CM9 I am experience a battery drain far worse than anyone else. Its frustrating to hear everyone else say there battery life is better. Perfect example. Last night I lifted it off of fully charged. Barely touched it. It showed after 55 minutes that it was down to 89% and 70% of that was screen use.
[Galaxy S II General] jsr84:
I guess the only thing for you to do is go back to the stock ROM...
[Galaxy S II General] dsixda:
I think the reason it went back to On Demand is likely because you did not check the box 'Set on boot'. I myself don't have such an issue. Again, that's a user issue, not the ROM.

I hear you, though. The battery life on this device is not the greatest. Neither was it on the original SGS2. I do find today, however, that the Conservative governor is getting better results than the default On Demand.

Nothing is being overclocked by default. The CPU is correctly being reported at 1512MHz by third party apps, and benchmarks report standard numbers for this processor. I'm not the nerd type who tweaks kernels and crap; in fact I just leave things as close to stock Android as I can.

BTW I didn't notice that 'TV glitch' effect you are talking about. I'm just wondering if your device is just defective to begin with?

P.S. I still don't know why you leave GPS on all the time. Since Day 1 it is a universal no-no in Android to leave GPS on when you don't need it due to battery drain; unless you want Google tracking your exact location 24 hours a day. There is probably a chance you have an app that remains on in the background polling your GPS location.
[Galaxy S II General] LVNona:
Just notice in new rom can't disable NFC.

Is there any way to change settings for automatic brightness - so when you are at complete dark room to get lowest brightness? Now if I'm in a dark room my brightes almost in a middle and it's too bright.

Anything else so far works great ;)
[Galaxy S II General] dsixda:
Huh? I can uncheck and check the box fine. There's no NFC support on the device itself anyway. If you have an issue then use logcat.

Settings -> Display
[Galaxy S II General] LVNona:
Realy!? heh....me too can check NFC box. But after go to Home page and get back to setting - still on.

Previous rom was no problems.

Display settings - awesome. You think I didn't try!? I can change manually Brightness. But my question - is there any specific advanced settings for brightness sensor and levels for automatic levels? I'm tired every time to switch from auto to manual.

Is it - Automatic backlight/use custom/other levels or something else?

Thanks.
[Galaxy S II General] dsixda:
What do you mean don't answer with question?? I'm not tech support, just go to Settings Display and check the custom options. Come on guys.
[Galaxy S II General] LVNona:
Simple. before I ask specific questions I already try to find different solutions - doesn't work. And If I ask something advanced I'm expecting answer. Nothing personal.

---------- Post added at 05:36 PM ---------- Previous post was at 05:34 PM ----------

That's the point - there is too many different options and i'm not sure wich one is the right one.

That's why I'm asking anybody.

---------- Post added at 05:43 PM ---------- Previous post was at 05:36 PM ----------

ok...figure out for NFC. Just check box doesn't help - needs reboot. Now fine ;)

Left only to figure out how the screen and screen settings works - if anybody knows - please.

Thanks
[Galaxy S II General] dsixda:
Why, did you purchase a service? I merely ported CM9 to this device in my free time, I could have just kept it to myself. It doesn't mean I know everything about CyanogenMod or that I'm also going to work on JB. Maybe somebody else can help you here.
[Galaxy S II General] dsixda:
If you are talking about the lowest brightness setting, then that would be under the Screen / Backlight / Custom / Dim Level setting. I don't think it's that complicated to find that. Although I agree other things like button backlight are hard to find.
[Galaxy S II General] LVNona:
I'm absolutely respect what you are doing and understand you - you are not obligated anything to us.

I post for everybody, don't take it personal ;)
[Galaxy S II General] dsixda:
Currently uploading:

Should hopefully be up in 30 minutes from time of this post. Server's been a bit flaky tonight.

To ensure you have no issues flashing, follow these steps:

- clear cache

- clear Dalvik cache (under Advanced menu options)

- flash ROM

- flash Google apps
[Galaxy S II General] dsixda:
For the 4 people who have already downloaded the July 20th build, sorry, but I have a newer version for July 21st ;) You can keep that one, but this new one should help with CPU efficiency somewhat:

I'll take down the July 20th one and replace it with the 21st build.

Being uploaded now.
[Galaxy S II General] LVNona:
Just notice interesting fact.

Usually for night I'm leaving Airport mode - to help battery - and from 100% in the morning usually 87-85% left.

Today by mistake I left my phone ON for cellular network & wifi - and my battery in morning was 91% left.

That's weird ;)
[Galaxy S II General] Spon4ik:
is there some way to port this mod to Samsung Galaxy S2 HD LTE (SHV-E120L)

is it posible to compile this mod with original modem etc? and maybe somebody can do that for rest Samsung Galaxy S2 HD LTE owners?
[Galaxy S II General] alexincanada:
New to Bell HD LTE

I picked up the Bell HD LTE today.

I came to XDA and was excited to see that there is a cyanogen 9 mod for this phone.

Thanks dsixda for the great work.
[Galaxy S II General] B.Moreira:
Why not the GS3? :p
[Galaxy S II General] dsixda:
This guy is working on it, you can message him: https://github.com/skysbird

LOL If I work on it my fragile wrists are going to fall off ;)
[Galaxy S II General] B.Moreira:
Dsixda, are you planning on making this rom into a nightly like you said, or do you not feel like it?

It would be awesome to see this rom become nightly from what it was almost a month ago. :D
[Galaxy S II General] dsixda:
Yes, official nightlies is my goal. Am working towards that.
[Galaxy S II General] B.Moreira:
Sweet
[Galaxy S II General] dsixda:
I sent a submission request yesterday so it will be under review soon.
[Galaxy S II General] dsixda:
Hi guys, I've put up a July 22nd build. It just has minor fixes for issues during the flashing process.
[Galaxy S II General] B.Moreira:
Good, that means it shouldn't be too long until it's official right?
[Galaxy S II General] dsixda:
No idea
[Galaxy S II General] deafened:
Latest build installed. Working great.
[Galaxy S II General] alexincanada:
My phone died. I needed a phone ASAP. This was the only decent smartphone in stock.
[Galaxy S II General] dsixda:
For me the SGS3 was just a bit expensive, plus a bit too big. However, I'm starting to feel that even the SGS2 HD is getting too big for my small hands LOL. I may just use something like an Xperia Ray for regular use and the HD for development or playing games.
[Galaxy S II General] dsixda:
Our ROM is actually moving on quite well, compared to the other SGS2 devices that already have official CM9 status. Main thing is that our camera/camcorder preview screens are actually working. But neither I or any of the other SGS2 guys have any idea how the cameras work... the Silly Face effects preview issue I'm having is similar to what they're seeing with the regular camcorder preview functionality.

I'm sure we'll get the official designation soon but I don't know how the process works.
[Galaxy S II General] TrueHD:
Do somebody know, where is bootanimation.zip in our Cyanogen Mod 9 situated? Wanted to change CM9 booting screen to that, but can't find such directory

/system/customize/resources/

, as adviced in topic...
[Galaxy S II General] deafened:
I'd be careful about changing the boot animation at this time. Since this is an alpha version of dsixda's ROM, you may break something.
[Galaxy S II General] dsixda:
That's because it's a Sense ROM, not stock Android, which has it under /system/media. I wouldn't try to use graphics from a qHD resolution device..
[Galaxy S II General] dsixda:
I would say we're closer to beta than alpha ;)
[Galaxy S II General] dsixda:
For those having battery issues, make sure you use any build from July 21 or newer, since it now has "mp decision" compiled in the kernel, which enables the device to use the mpdecision binary under /system/bin. This controls the CPU efficiency.

You can also set the CPU minimum frequency to 192MHz rather than the default 384.
[Galaxy S II General] dsixda:
I've uploaded the July 23rd build:

This is the way BLN normally behaves on other devices -- I'm glad we have the blinking now.
[Galaxy S II General] deafened:
LOL Yes I agree!
[Galaxy S II General] TrueHD:
Thanks for advice, i will not do it then. Just thought it's working on any device as stated in that topic.

P.S. May be a noob question, but with the latest ROM post dxdia said before flashing i need to clear caches. But it means that i will loose all my settings and installed apps, right? Is it any way of backuping all that (i have heard about something called similar to "Titanium backup" - don't know, what it means), or after recovering this backup it is possible to have additional glitches, so it may be more safe to correct all settings as i like and install all my apps from the scratch?
[Galaxy S II General] dsixda:
Who's dxdia? ;)

Cache has nothing to do with your data partition. It's like temp files on your PC that were created by some software that can be safely deleted.
[Galaxy S II General] deafened:
The only reason I would leave this ROM is if Bell put out 4.1 for it. Then I would wait for someone to do CM10 and switch back. :)
[Galaxy S II General] dsixda:
To change the blink duration and interval of the backlight notification, go to Settings / Display / Notification Light, and the option under the first check box.

EDIT: Ok, well it looks like setting the notification lights to "Always On" sets it to a fast blinking state, not necessarily always on. This is a known issue and the S2 guys will be looking at it.
[Galaxy S II General] deafened:
Anyone having issues with Phone using so much battery?

Using build from 22nd.
[Galaxy S II General] tgiannelli:
Sorry I have no answers or a link but I thought I remembered seeing some information about a default draw on the battery that was a decimal off. Where it was 34mh instead of 3.4mh.

I can't for the life of me find that post again.
[Galaxy S II General] dsixda:
Same here ... it's higher than screen time even though I used the phone for less than 10 minutes today.
[Galaxy S II General] B.Moreira:
I have no problem with the phone, it doesn't even show up on the battery usage thing. :confused:
[Galaxy S II General] deafened:
I installed the July 23 build and calibrated the battery this morning. I'll check later today.

+++EDIT+++

Things look fairly normal. Made a couple of short calls today and they register correctly.
[Galaxy S II General] colinoftheeast:
Latest build is working great for me. No battery issues. :good:
[Galaxy S II General] nsblue:
works like a charm!

switched from an iphone 4s to the sgh 747 and to be honest was starting to regret it only because of the battery life... had no clue what roms or rooting was till two days back and i must say you made switching to android worth it... my phone battery is amazing now... after deleting all those bell apps and cyanogen 9 is amazing... makes ios feel like im using windows 3.1, i havent even put my phone on the charger and i havent put my phone down since i installed it two days back.... im glad i found this or else id probably go back to ios if it wasnt for ya.

thanks again
[Galaxy S II General] TrueHD:
Oh, thanks 4 info) So is it make sence to just clear that cache sometimes to speed-up my phone?

P.S. Sorry for my mistypings of eng letters:)
[Galaxy S II General] dsixda:
Cache files are sometimes needed to perform operations faster, eg. Web browser will cache a page you already visited so that the next time you visit it will use the cached copy for faster access. Just Google it

On the other hand the cached files of one app may interfere with a newer version of an app if it's no longer compatible.

[Galaxy S II General] AllyKat:
Which battery calibration app?

Another question in response a few back in the thread? Does anyone have the original Boot Animation for the device?

---------- Post added at 12:51 AM ---------- Previous post was at 12:44 AM ----------

I was something to do with my Motorola Atrix that made me think that I needed the GPS on all the time. Google Maps on my last device would not activate GPS without it being turned on all the time. That is turned off now...

The TV glitch... only seems to happen in Twitter.
[Galaxy S II General] botay.alls:
Please tell me: Can I use it for Samsung S2 HD Lte E120L ?
[Galaxy S II General] deafened:
I use https://play.google.com/store/apps/details?id=com.nema.batterycalibration&feature=nav_result#?t=W251bGwsMSwxLDMsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd to calibrate.
[Galaxy S II General] dsixda:
No idea about the Atrix issue.. that's not right. If you want quicker GPS locks then you only need A-GPS turned on, which finds your general location based on the cell towers (and GPS is used to narrow down the exact location). This is already built into most smartphones.

TV glitch? Are you confusing it with the auto brightness setting changing the brightness by itself?
[Galaxy S II General] sunhao0913:
I`m using a changed version of your rom, I`m in China and the signal is not good, I`m just wandering if you can do somelittle change to make the signal better...gsm only, no 3g

i haven't install any between 13 and 22. i'll try them all this evenig and keep you posted.

do you wipe data & cache between each flash?
