On my Desire I did it so I could get rid of all the operator rubbish and take screen shots, on my S2 its unbranded, unlocked, and can take screen shots out of the box.
It seems allot of peeps out there just flash roms for the sake of flashing, curiosity I guess. But I am getting the feeling very few actually take the time to read up on what any particular custom rom actually aims to do, thinking every rom is a silver bullet.
Official roms are a good solid middle ground where things like stability and battery life are the denominators. Some custom roms aims for a more elaborate GUI while others go for overclocking or perhaps fast adhoc bug fixes, again there are no silver bullets here, they all tackle different needs.
If you plan to try out custom or unofficial roms I suggest you read up on a few things like:
If it will impact your warranty
Do you know how to get back to stock
How do you get Samsung official updates after custom flash
What are my needs and what rom match them
I have tried out a few roms myself on a plethora of Android phones and always ended up back on stock roms. The only exeption was my old Galasy I7500 that never got a official rom above Cupcake and when Google started implementing features in Maps and Gmail that was only supported by Donut and above I was forced to go AOSP.
I agree their is currently very little performance difference between stock and custom roms .
Debrand yes via Stock Samsung rom but custom rom your choice read the posts in each rom to get an idea .
Saying that i run a Frankenstein rom with bits from here there and everywhere .

For Stock ROM vs Custom ROM from stock derivative, there is overclocking and under-volting Kernels. So there can be a performance increase and lower power consumption depending on what the setting is.
Another difference is that there are certain "bloated" apps removed, or "better" apps pre-installed.
Such derivative roms are Lite'ning, Skyrom, etc.
As for Stock ROM vs Custom ROM (Non-Stock Derivatives), this is no longer a Samsung ROM, so there are no or little Samsung features and apps.
Non-Derivative ROMs are like CyanogenMod 7, etc.
The real advantage is that most of custom roms are more battery friendly then a stock one, makes your phone faster and very offen fix stock bugs.

I would agree with this myself.I have just answered a thread somewhere else where someone wants to root & flash their new phone & they haven't even got it yet.I say "Have a play for a couple of weeks" Change some of the apps for one's from the Market & give it a chance.You might just stay with the stock rom.I know I did.

I don't agree with this at all, more often than not you will get substantially better battery life on custom ROM's as opposed to stock,not hearsay this is fact, not to mention more speed and less lag,etc,etc the limitations and possibilities are endless.

Your view mine and based upon my testing is their is not much difference .If their was you would not have so many complaining in each rom thread about poor battery life .
Much better battery life and the majority would be running that rom only .
Possibilities may well be endless but at present no significant improvement such as their was on SGS1 .
Thats my view others as usual will agree and others will disagree .

Although I flashed my Touch HD and HD 2 like crazy on SGS II it does not make much sense.
Only if You want to have a special theme You fell in love of it makes sense ............
For me: I start flashing when Darkedge-Theme is available for CM and CM is really flawless ....................

Well on the stock ROM i was lucky to get 15/16 hours battery life, on custom ROM's (for example Cognition 1.15) the highest i got was 28 hours 57 minutes, that is a serious difference in battery life, this is with pretty much the same usage - internet,calls,texts and music,people are always going to have issues with battery life regardless but if they follow some procedures good battery life can be achieved, installing Juice Defender ultimate should be their first step, of course your entitled to your opinion
I flash custom rom because the homebutton lagfix (reacts instant now) and removing all the text messages from my log. Looks really messed up with all those sms. And ofcourse theming

Sorry not opinion fact stock rom for me had good battery life increase in battery life with Villain rom Cognition rom and varying kernels gave no noticeable boost to battery life .Thats the principle reason i answered the question with my views .
However that does not stop me from running custom roms , Frankenstein/ further customized . Nor should it stop anyone experimenting with such .
Personal view re battery life is that correct procedure regarding the apps that can be deleted frozen and good battery management will be better than flashing a custom ron just to gain a hoped for better battery life .Thats why many that are running custom roms are totally disappointed as they are approaching the problem from the wrong end to start with in regards battery drain .
But i am sure with two contrasting points of view the OP is now better informed than they where .

Tá mo bhríste trí thine!
I forgot another reason.
Most phone manufacturers including Samsung and HTC, have a 18 mths support life, once the full 18 mths are up, there are no more upgrades or official rom releases from the manufacturer.
As for Telco branded phones, roms updates almost never appears unless there is some major issues with the shipped rom.
Custom ROMs just keeps coming out almost every night. They release fixes faster than manufacturers and you don't feel forsaken like waiting for a rom released by your telco.

sorry, I don't have enough posts to reply to the already started thread over in the dev forum
http://forum.xda-developers.com/showthread.php?t=995819
basically I wanted to know, is there any way to flash to this latest "PG05IMG_Mecha" ROM from that Chinese site but NOT completely wipe the phone & lose all settings, apps etc. I spent the better part of the entire weekend setting up and tweaking all my settings just right. would hate to start from scratch but I do want the battery life enhancements of the latest FW.
cheers guys
No, currently there is no way just to flash that stock rom over top. What battery life improvements are in the newer rom?
Well I don't know the specifics but I believe they optimized the power saving algos a bit, I know HTC has been tweaking them to try to squeeze a little more life out of that tiny battery.
Does it also have a custom kernel? I know the largest battery savings I've seen from my experience w/ custom roms came from a custom kernel that was geared to save battery life.
I can't find any information on the thread you linked about it having any battery saving benefits.

Yeah I know they've barely gotten roms w/ no bloatware out so far, which is a miracle in the turn around time from the device hitting the market. But sure they'll be there soon. So just interested in how this ROM manages to accomplish a battery savings.
Upon looking at the message in the thread about battery savings. If you remove bloatware and apps that constantly decide they need to be running you'll see a noticeable increase in battery life with that. You could also constantly fight to kill them and likely also see an increase in battery life. But the increase won't be as significant as when the custom kernels come about.
So if you aren't readily familiar with the manual process for flashing roms or say get a rom from a more reliable source (developer)... you might want to wait for roms to start showing up on ROM manager that'll automate the process for you and hopefully by then the custom kernels and other such options will be available. But I don't really trust a link for a image for my phone that sends me to a foreign website. You might want to check out adrynalyne's basic debloated ROM??

So im using MIUI Galnet ICS with Siyah kernel, and i completely love almost everything about this rom, but i say almost because my battery life is not so good i get like 13 hours with pretty low use.
So my question is:
What rom has the best battery life, fairly smooth and stable (battery life at highest priority)? What would be the best kernel (battery wise) to use with this ROM?
Another question kinda not on topic but anyways;
If my phone fell a few times (sometimes on side, sometimes on screen sometimes on back)(with screen protector and back cover) can any of the internal components get damaged? cuz sometimes the phone gets minor freezes.
P.S.
I have been told CheckromRevolution 5.5 is probably one of the best roms battery wise, the thing is there is CheckRomRevolution HD 3.1.x now
So which CheckRom ROM has best battery life?
The best ROM for battery life is the one which is so bad, it makes you not want to use the phone.
Currently using Simple and Clean with Speedmod. Pretty good, but it's just my first discharge cycle so I can't judge yet, but I definitely see some improvements from Litening. CheckROM and Sensation 1.9 also seems decent. Cognition as well.

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.

Hi all,
First post, so please be kind
I currently have RR 3.1.2 and SuperNexus build5 installed on dual boot on my GT-I9300. Although both are good ROMs, neither fullfill my requirement of a couple of days of battery life. My original ICS Samsung ROM would last this long. It wasnt until JB update that I started playing with new installations due to my bat life being almost 1/2'ed! What I'm now thinking is possibly to keep RR ROM or go back to Samsung JB ROM on main boot, and on 2nd boot install a very lightweight ROM that will be good at preserving bat life. I need this for days away using GPS mapping/tracking software together with photos. Energy HD sounds good, but hasnt been updated for sometime and is ICS 4.0.4. Before I go and install that, are there any more upto date similar ROMs around? Of course, I could always go back to Samsung stock ROM on 2nd boot, but am aware, its got a lot of bloatware installed.
Thanks for your advice!
Dave

Thanks for the reply JJEgan, very useful link to all the ROMs. So it looks like SuperNexus ROM should be long lasting, being AOSP, oh!
Am I going to have to try all 23 other AOSP ROMs and work it out myself :laugh: Think I'll start at CM10. This might take sometime!

You should also search for "better battery stats" apk around here, and check what is the cause of your power consumption - the ROM almost never is, usually it is a group of apps that keep the device from getting into deep sleep. GPS locators and other anti-theft programs are on that list, also programs that try to update often over network. MyProfiles was also creating a large problem on my CrisKelo-based configuration. On certain hardware configurations with permanent data connection there might be other problems with fast dormancy on network and other stuff.
How is everyone liking the KitKat Roms?
I'm thinking of upgrading because I'm getting pretty bad battery life with AJK 4.9 and Supernexus 2.0 (Android 4.1.2). I just got a new battery for my phone and that's when I realized that it wasn't my battery that was the problem.
BUT
My phone's charging port broke recently. Like, the innards of the port make a snap sound and fell out. So I have no USB functions on my phone any more so if my phone bricks mid update, I'm SOL. Also I am swapping batteries out half way through the day because my phone consumes power too fast.
So, any recommendations on KitKat kernels? Roms? I looked at RenderBroken's but I'm not sure if he's in the process of putting a new one up or what. The only downloads on his sight for the i777 kernels were in the "Old Builds" folder.
Also, doesn't holding the power button and both volume buttons boot into recovery? Because it's only going into Odin.
Preferences on ROM's?
Thanks in advance!
I'm sorry, I have a difficult time believing AJK kernel is the reason behind your battery woes. That kernel is very likely the most stable, tweakable, battery-friendly kernel ever made for our device, so if you are getting bad results with that... well, nothing else is going to improve matters.
A few things: stay in your current setup and run Better Battery Stats and Wakelock Detector. Between those two free apps you'll be able to see EXACTLY what's causing your problems.
KK roms take a bit more toll on the battery, and require a lot of tweaking to get things under control, due to the framework changes Google made. If you're worried about battery life you may be better off staying on JB until you discover the real cause of your battery problems.

I'm not worried about battery life so much as I just want to get through most of my day without having to swap batteries (which are brand new mind you). I updated to SuperNexus 3.0 so we'll see if there's any improvement of battery life.
What do you think about KitKat so far though?

I would advise you to stay off of Supernexus roms; they've long been abandoned and 3.0 especially was buggy. Try Renders' CM builds if you're wanting supported stable builds, or look in the ported section. Overall KK has performed great for me.

Ahhh but that means I have to switch kernels because I'm using AOSP. What about Render's 4.4 kernel? I looked at his thread but the link to the download only shows old versions. Are there any other 4.4 kernels working?
No, his kernels are great, you have nothing to worry about. Just make sure you thoroughly read what's required to make the jump to KK before you attempt it.
at first: this is not a "whats the best rom" thread.
i have 2 very focused questions:
What are the idle times with those different roms?
Are there some Main feature differences?
Aktually im running cm11 m5 snapshot with smartassv2 Governor. its smooth but the battery life is kinda poor.
Im looking for a rom with long battery life. And i dont care about google now, talking to my phone(ok google) nor i need the special features from the standart samsung rom.
Would be realy helpfull if u can review to my questions. Greetings!
pls apologize my bad english.
1 each phone is different depending on what's installed and running.
2 read there threads or flash each ROM and find out that way. You forgot about aokp?

There are no definitive results, I have used both and I keep coming back to Omni due to the fact that on SlimKat music stutters like crazy when the screen is locked. Also, Omni updates are small enough to update often without having to download a complete update, to many users this a huge deal due to data limitations in certain countries. As for usage, idle time etc, like stated before, that depends entirely on what is installed on your device. Install a bunch of apps that need to constantly receive data updates and you will have battery drain and very little deep sleep. Where features are concerned, you kinda learn to live with limitations due to missing features on a specific rom. If you really want, you can most likely find an app that will bring a missing feature to a rom. I see a lot of people throwing their toys out the cot because one of the other does not have a specific feature implimented, yet the developers have done so with good reason, usually either performance or battery life.
With all said, there are many roms out there, Omni and SlimKat aren't the only players. It's difficult to compare roms nowadays because you are never quite sure if your kernel tweaking or custom kernel with it's hundreds of tweaks is the reason for a device not going into deep sleep either.
Give them all a try and decide for yourself, nandroid backups and apps like Titanium Backup makes it so easy.

Thx for your long, interessting and helping text!
im missing only 1 thing. if someone flashes all roms, doesnt install any apps. Only new rom and full wipe before, restart and tracks the time the phone has battery. Dont u think this is a possibility to compare the roms battery usage? i think there is no one who does this, but i probably will try this and put down a little table here. so people like me are able to see the rom with the best battery efficiency. so if they decide this rom has not enough performance, they can switch to "battery efficiency Number 2" and so on.

Sure you can do what you stated but bear in mind how will you compare the battery life across roms..
There should be some standardized test... Like looping video playback or some other method which does not change based on you usage habits..
Sent from my GT-I9300 using Tapatalk
Pa is another you're missing from you're list of developed roms. What you could do is test video playback, calls incoming/outgoing,one game of choice "high end battery draining game" and compere them all. As for the kernel tuning.. Read about what really happens and you will fine not a lot does happen with UV/uc .

You can compare but you have to use that phone for more days not like just one and you have to full charge and then discharge 2 or 3 times till the phone make the correct battery stats. So i think you can test but better with daily use or get an app that drains battey faster well i think this may work
