guys, I'm really bored with the stock rom. i never ever flashed any rom on any of my android phones...that makes me a dumb noob obviously.
Now i want a lit'l help from you all, info to be precise.
hows the battery life on CM9? is it good for everyday use? i've searched alot but didnt get proper pros and cons...so it'd be great if you provide any info.
Also, can i come back to stock with ease?
PS: i have rooted it with cf root 6.4
From my present experience, one the battery has been calibrated, CM9 gives excellent battery life with the Galaxy S3, similar to the stock rom. It also gives flexibility in setting the CPU governor to save more power or get better performance. However, when I first flashed, battery calibration was out of whack and I got only 5 hours standby. After a charge cycle, that was fixed, and for example, my phone was at 98% two hours ago, and after two hours of standby, it is still at 98%.
Battery life is wicked mate and yeah you can return to stock....either make a back-up and restore when you want it (your device will still be rooted) or read a guide on how to flash back using odin (you will lose root)
Hope this helped buddy

thanks a ton friend....can you give me a link for both...flashing CM9 and Stock!
also, is the nightly build good for everyday use?
CM9 Thread for your Model: http://forum.xda-developers.com/showthread.php?t=1714354
The nightlies are fully usable from my experience, and your model has very few significant known issues. The linked thread, particularly the first post for more info on known issues and such.

Dude, before flashing anything up need to on how to: backup rom(nandroid), use Odin, flash with cwm, recover your phone after bad flash(semi-bricked, its easy) and how to backup apps and settings to easy restore 3rd party user apps(eg titanium backup)
So read as many thread as u can before 1st flash
Agree OP really needs to understand the basics before going further .

My dad just got the Froyo OTA on his fascinate, and the battery has been running dry in less than 3 hours without use, where on 2.1, he lasted all day with over half battery remaining.
I was looking into rooting his phone (I have my Inc rooted already) to get new ROMs/kernels to improve speed/battery.
If anyone could link me to an easy guide to root the fascinate, and suggest new ROMS/kernels that would give me better battery, I'd much appreciate it.
Thanks guys!
I would suggest reading through the stickies. All of the info you're looking for is in there.
I personally use both ComRom and Evil Fascination and both have pretty decent battery life.
Also FYI: this post is in the wrong section. There's a Q&A board for this stuff.
This should be in Q& A, but I had good luck with compromise 2.0 and a corresponding kernel.

If the official ota is burning through battery like that, then he needs to take it in. There's something wrong with the unit.

That is not always the case, do a factory reset first, he may have had a app installed that worked just fine in 2.1 but may have a update for 2.2 because the original app may have issues with 2.2 like battery drain.
But always always always, either remove apps or do a factory reset before even considering taking your phone in to be replaced.
where do I go to flash esn? the 3G symbol still shows up on his phone, and seems to be working...how can I tell?
*EDIT* though to be honest, rooting, based on my own experience, is completely worth it if only for the ability to back up the phone lol
Look at the time without signal. Unless I put the phone in airplane mode for a few seconds after I reboot, I have a time without signal of around 50%. This is killer on the battery

As far as rooting and roming, use Odin to flash CWM, then boot directly into CWM, then flash custom rom of choice (i like com rom, but also hear good things about evil fascinate). That's about as easy as it gets, imo
Sent from my SCH-I500 using XDA Premium App
so if this is the case, you'd recommend turning airplane mode on for a few seconds after booting?
Yes. Wait for media scanner to do its thing, then turn on airplane mode, wait about 5 to 10 seconds, then turn airplane mode off. You should see time without signal drop.
Edit: to view time without signal, go into settings - about phone - battery use - cell standby in case you didn't know

There are so many ways to go about rooting the fascinate. Odin is the simplest. If you Odin your phone with CWM you can go anywhere from here. Use this Odin package for CWM.
http://dl.dropbox.com/u/36791/CWM3_Voodoo.tar.md5 Brought to you by times_infinity.
Then download and install the ComROM with the undervolted PBJ kernel in CWM if you are going for battery life.

Ok, so would I follow the sticky in the Q&A section that tells how to get to/from stock with Odin, and then use that file? Or is there a better guide on using Odin?
Does the ComROM come with the PBJ kernel or should I just search that on here?
Sorry for all the basic questions, all of this stuff is waaay different than hitting "start" in Unrevoked and then just hitting "install zip from SD" in CWM lol
There are 3 versions on Com Rom, and the only differences are the kernels. One has no kernel, one has OTB (that's what I am currently running, and am getting stellar battery, with no undervolting), and one that has PBJ.
I assume you would just use that sticky in Q&A, as it is the only sticky in there. I have never looked at it, so I don't want to tell you one way or the other.

While I still want to root, just to tinker with the phone and backup just in case, after a battery pull & wait one minute last night before charging, the phone now has over 80% battery after a full work day, so it seems to have worked.
Thanks for your help guys, I'll probably be back to ask some more questions (in the right section) in the future!
Hey guys,
I have a question, I have my SGS II, and I tested out alot of roms and kerenels but I just cant get to a promising results regarding battery life.
My question is:
What is the most promision ROM and KERNEL combo for BEST battery life?
Really? Really? Seriously?
I think you should use stock Rom
Sent from my GT-I9100 using xda premium
Yea... Stock if you want battery
Unfortantuly my stock rom sucks, laggy and ****ty.
And cmon guys stop tagging this post as span n other **** I am new to this all new android stuff and I see people with effin 3 days of battery life while in 100% mine only lasts for 8 hours.
Be more serious.
So, did you read up on how they were getting it? (3 effin days battery)
Have you then tried the same thing?
Checkrom revoHD.
Well for me checkrom revo HD with leoMar kitchen app is simply the best. This combined with Dark Knights Siyah kernal is the best combinition for me. I get a full day of battery charge with heavy usage.

They diden't mention to write.
Only pics.
This will depend on so many variables, network, location, Modem, ROM, Kernel, user installs of software, wake locks, bad signal.......
Hence the only way to find is via flashing bedding testing....
As you will notice users can have same setup but very different outcomes..
Using CWM backup you can always revert to stable setup.
On that note thread closed...
I own a Droid 3 but my dad has the x2 and he needs better battery life so I plan on rooting the phone and putting a custom rom on it for him so I wanted to know which rom would be best for him. He uses e mail phone calls and texts a lot and sometimes YouTube videos. If someone could post links for the best suited rom for him along with any scripts that help performance as well as battery that would be great. Also, do I need to install a custom recovery from somewhere else or do I use cwm from rom manager?

Here is everything you need for this phone:
http://forum.xda-developers.com/showthread.php?t=1313103
Any rom will essentially have better battery life since they are all pretty much stripped down versions of the stock ROM. I suggest eclipse. The speedy script and battery fix script are very highly recommended too.
EDIT: Rom Manager doesnt really work with the Droid X2. So you will need the Bootstrap Recovery in the link I posted.

Thanks, there's a lot of scripts, which would u recommend flashing over the eclipse rom?

The battery fix is a must if you want accurate reading. I am running eclipse 1.3 with speedy v7. Also v6 supercharger but that is more for my gaming. And also the mash up v .5 I am getting between 10-14 hrs on a charge and that is pretty heavy use. On my day off I can go between 8 and 10 hrs but that is very heavy use then. Oh ya make sure you wipe battery stats when you flash or calibrate it after.
All are safe to use, which is why they were put in that thread. Just read every threads OP before flashing since they usually have instructions to wipe certain things. And I believe the mash up script tells you to turn wifi off before flashing. Just read and you will be good.

+1 thanks I should of mentioned that.
Ive had my best battery life with Eclipse. Ive been pulling 20+ hours with moderate use. Mostly texting, checking some web pages and trolling XDA and Facebook.
Ive also seen an increase from turning off network provided time under date/time in settings.

I can vouch for the turning off of "network provided time"if settings. It seems the phone "sleeps" better when it is idle.
Also another way to ensure better battery life is by getting into the habit of REBOOTING the phone(power off/on) after EVERY TIME you take it off of the charger. There is a thread explaining why this helps ...I just don't feel like looking for it right now sorry lol

I think its a problem with stock GB (seems to be a few issues with stock). But it transfers over to the ROMs because there is no fix for it yet other than to restart.
I've been reading up a lot about custom ROMs, and more often than not CM9 always gets a mention. I'm tempted to flash it but just wanting to know is it really worth it? Does it have major improvements on battery and performance, and what are the main things that make it so much better than the stock ROM?
Also is it easy to revert back to the stock? I've already got my phone rooted with CF-Root, is that the clockworkmod recovery I've read about, and if so can I just go ahead with making a backup and flashing with CM9?
Any help/info would be appreciated.

Its users choice read what does not work first .
CF root is not Clockwork Recovery but it probably has CWM recovery incorporated .
CWM manager in apps and boot to recovery should show CWM options .

CM9 is experimental and still has several flaws and issues.
I'd not recommend it for everyday usage if you're not a developer or like living on the edge.
Plus, 3G battery life is terrible since CM9 has no Fast Dormancy. Within ~5 hours the battery was always dead on me.
Samsung-based Roms make it more than 24 hours in contrast.
It will of course get better when the ROM is properly fixed and all features integrated. It always does =)

a lot of the battery issues are due to not resetting battery stats. You fully charge the phone, clear the stats, then charge it again I think? Search there are instructions.
I've got CM9 on an Atrix which isn't even a supported device and it's totally daily usable. The only things I lose which are only b'cause it's an atrix are:
Fingerprint reader
Webtop
video camera
Check out what works and doesn't with CM9 for your phone and decide. I like it a lot, it's TOTALLY stripped though, like no google aps (you can install them as a package)... There are lots of weird intricacies to it but it's cool as hell IMO

At least the build for Atrix is not pre-alpha EXPERIMENTAL =)
It takes some time for the developers to get it right on the S3. I've never said CM9 itself had issues, it's the combination of CM9+ i9300 that needs some serious work.
I have or manage a couple of CM9-flashed devices (from Galaxy S1 over Galaxy S2 to Motorola Xoom) so I know how awesome the Rom is =)
Cheers for all the replys.
Are there any other custom ROMs worth looking at? I've heard CM9 is the most popular but if it's not quite usable daily yet I might give something else a try.
CM9 is currently very usable. I have no problems whatsoever. It has many advantages to stock ROM like no low free memory problem, no launcher redraws and no lags. The only real disadvantage is that the camera app sucks compared to stock.
It must like your phone better.
Kept turning off the modem for no reason, sometimes restart was necessary to connect.
It also has no fd as already described, so many people will notice a huge drain in 3g.
Btw you can easily get rid of memory issues by freezing/removin, all the apps you do not need but which are always running.

Hello to all,
after having a stock i9300 for 11 months (I never kept stock for such a long period of time) I decide to install a custom rom.
After reading a lot I noticed that the most popular rom for the S3 i9300 is the omega so I followed that route.
I intalled the latest 4.1.2 version yesterday and today I was surprised to noticed that the battery lasted less than 14 hours.
I did a clean installation wiping cache/delvik etc.
This performance is horrible compared to stock.
I could easily make a whole day regardless of usage.
1. Are all roms as bad?
2. Will a possible change of the kernel provide a solution is so which one?
Other than that the rom looks great with some added features from the 4.2.2 which look great and fresh.
But I can not accept the phone not easily go through a day.
I also noticed some issues with Skype (not the latest version as this did not work well even on stock).
thank you
p.s. I could not post to the omega rom due to the fact I am new here......

You are being judgmental.
I spend several days reading the forum and educating myself.
I did read in the omega topic that some people experience battery problems.
Some of them reported that a different kernel provides better battery life.
I did not notice though that after flashing a rom you need several cycles for the battery to be calibrated.
Furthermore, in most roms I read about there are several people (not all) complaining about battery life.
This is why I asked if all custom roms increase performance while decreasing the battery life.

I also used Omega once but the battery life was just like yours.
Try doing the following:
1. Download greenify, understand how it works and greenify your apps.
2. Install startup manager, disable useless apps.
3. Disable wifi settings such as "notify me for new networks". Also, while in sleep mode, make sure the option is set to never.
4. Put auto brightness on.
5. Disable sync.
You can go ahead and install a different kernel. Googy or Devil or siyah would be a great choise.
All of these should improve your battery life.
Thank you for your reply.
Out of curiosity why does this rom consumes more power since it does not over clock the cpu?

They are many factors that affecting your battery life.Everyone have different angle viewing things. So depend on them what a good battery life mean to them. You can try other rom though. I'm using foxhound 2.5 with googy max kernel. It bring a good perfomance for me. And you can try to buy a 3200mah battery for your S3 with original size xD It can last more longer. And try the comment above it should improve the battery alot.
well I always try not to leave wifi on when not in use and do not run programs that use battery resources. I do never use mobile data and gps is always off. I did install greenify but there was really nothing running on the background.
Still I am under the impression that the stock rom provides signifficantly better battery life.
So my question is why? (Only out of curiosity).
