I am a jailbroken iPhone convert. I am loving this phone so far and have heeded the warnings to not mess with the phone too much. My question is, when is it safe to use the roms that are available? Is there that big of a difference in performance? I jailbroke my iPhone to get features Apple wouldn't allow our have. what do I gain with custom roms? Thanks for all that has been done so far and look forward to what its to come.
I don't know of there is a time period to use them but most custom roms freshen up your desktop icons as well most of them improve battery life and add the ability to overclock.
You can gain quite a few features with Custom Roms. Such as overclocking, custom ui's, much better performance (snappier). I highly recommend flashing a custom ROM. Currently CM9 and CM7 are a work in progress and should be released sooner than later, (CM7 is currently in it's testing stage). Also to do all of this you have to root your device. A guide can be found here: http://forum.xda-developers.com/showthread.php?t=1327741&highlight=how+to+root Keep in mind many features can be gained once rooted, but as you probably know the warranty is voided.
Thanks for the help so far. The only question still remaining for me is; at what point are these roms considered stable enough for someone new to start using. I have read the warnings and really don't want to have to reinstall everything over and over again because of instability issues. thanks

It really all depends on what you are after.
I will say that even the stock ROM on the Atrix 2 is not that stable, and there are a TON of bugs in it.
All the ROMs that are here are in a beta format and are not even at a 1.0 revision yet. If you are not technical at all, and don't really like playing with your device a lot, and flashing ROMs, to try and get a feature that the stock ROM is missing, then I totally advise against flashing anything. These "ROMS are completely safe and stable enough", but both lfaber06 and are I always trying to "improve" on them, no matter what revision that the ROM is at, as well as requests for new features. That really is why it may seem that people are flashing all the time, not really because of instability.
Since he and I are really the only two devs in here right now, there is not going to be a lot of choice in ROMs and since this phone is still fairly new, everything is still "new" and in beta/alpha. Since you are coming from the iphone, and flashing ROMs is not really something that you do, I say you wait until you find something you really want that is not available in the stock ROM, and has been put into one the ROMs available here, then try flashing that. Until then just hang tight for a while. There are plenty of hacks that can be done to the stock ROM, to fix things, and make that better at this time. Also take some time to learn a little about android and flashing and how it all works, not intimately, or on a very technical level, but that might save your "you know what", if you have an issue during a flash or while running an unfamiliar ROM.
Thank you VERY much. That was the answer I was looking for. I am technical savy, just haven't done much with android so far. I am one that likes to tinker and get the most out of any of my electronics.
I know. I can read. I have read OPs and most posts. I want to know what makes each ROM/port different. Each of them have almost same features and looks. I'm asking comparing CM9 vs Stock vs AOKP vs Slim vs Beam vs etc and cMIUI vs MIUI. I'm not complaining, just want people to share what make them choose one ROM over the other because all are smooth and fast and awesome and so on the same generic descriptions... Let's be honest, most of the has mainly same features, like to mod battery icon, clock, toggles, drawer, theme, lockscreen, some apps here and not there, different bootanimation, etc... you know what I mean. So what is it then? Please, elaborate some answers.
To me, there is a noticeable difference between all mentioned and RemICS and so with AOKPCB but mostly because of the theme/looks and some apps and few features.
I would like to read something else than just "X ROM is fast and smoother" and yes I know everyone is different so they get different experience with their ROM of choice, but what makes you choose a ROM over the other. That's the thing
No trolling allowed and it's not my intention to offend anyone. I appreciate all projects and stuff here, I'm not complaining. Just curious.
U can go to other forum like i9000 and nexus S and ask this question there, too ...they r just for your own choice lol, just flash one u like

They basically all come from the same base as far as Android OS goes, and as far as comparing no one can tell you what to choose. I know you are not asking for someone to choose for you, but that kinda is where the question leads. Compare them for yourself. See what you like. They all have their own flavor, mods, tweaks. Some are closer to stock, others are heavily modded. That's your answer in a nutshell. No one is gonna sit down and draw you up a chart of features for each rom.
@dao
I can ask there but that's not my phone and that doesn't answer my question. It's obvious they are there for choice, how to choose then? Why? That's what I would like to read. BTW, thanks for updating RemICS.
@greg
I have used them all. That's why I'm asking.

You just have to choose what you like and what works for you. It's that simple. Until Aries is released and we have an updated kernel, they are all about the same, but Aries will fix some issues. Like those blasted capacitive back lights timing out.

What made you choose miui for your phone? Did you try different ROMs before?
@HKSpeed
Oh, I haven't updated that... I'm on CM9 at the moment. My ROMs of choice are Team Acid's. I have been using their work since Froyo so I'm biased. I was on AOKP but battery was a big issue for me, it drained very fast, so I went on CM9 to see how it works since most other ROMs are based on it. Thought it should be more simple, less tweaked. I have tried all, except Linaro and Provision. I like them all but somehow I can't notice difference between them except but a few little things here and there.
I was on MIUI because Dao kept updating it and fast. It was more advanced than other ports/ROMs, then I went on AOKPBC just to see and the theme was too heavy, awesome but not what I was looking for.
I'm not saying I will stay on CM forever, might go on a flashing rampage sometime soon. I know these are WIP that depend on kernel so until then I shall keep experimenting.
I know the others have said pretty much the same thing I am saying, but it comes down to a matter of choice. The ICS roms are all CM9 base if I am not mistaken, so you are dealing with mostly the same issues and bugs on each, so it really comes down to a point of which theme you want and which apps/bloat you want. It becomes a real pain to have to debloat/rebloat a rom and I only ever do so if the theme and layout is custom and really nice but fun to use. If it's basically a stock rom and doesn't have typical apps/bloat/mods/tweaks that I am used to using, I hit the thanks button for the hard work that helps future devs have an easier time and keep looking for a rom that has everything I want. Right now, I am going to be selling my phone soon so I can get a SGS III at least, or maybe wait to see if the rumors are true and T-Mob gets the One X+. I'm drooling over that OC'd Tegra 3 ::fingers-crossed: But, that doesn't mean I won't be trying out different roms at the moment. I love the ICS roms but hate that I can't use calling over wifi. I know there are other options, but they are a bit of trouble with linking google voice among other things, so ICS isn't really for me yet even though it is beautiful. There's my choice...what's yours?
Ive tried to not post but it bothers me when people cant understand a simple question.
Chris31jct is NOT asking for you to convince him. He is asking why did YOU choose a specific rom.
He is also asking for a reason other than the generic responses given 90% of the time.
I started out on aokp then when slimics was released I used it for a while. I wanted to try aokp to see why it was so popular. I like aokp the customization options its a nice rom. I wanted to try slimics just because it doesnt have all the extra apk that aokp and cm9 have that I never use.
Most of the time I will test a rom just to see what the hype is.
3 things decide your choice of a ROM:
Stability
Customization
Battery consumption
In terms of Stability, Usually the higher the customization and options of a ROM, the more conflicts it has( not a rule).
Battery should be the same on all since they use same code and kernel.
Graphic Customization: AOKP is the Best
Settings and options: CM9 is the best
Stability + Battery: I personally prefer SlimRom or Stock cuz it has the most required customization and its very slim( about 80 mb) so probably lighter on your phone.
I wasn't trying to convince him. I know he'll choose whatever rom he wants and that's not for me to decide and/or judge. I was merely stating why most of us choose the roms we choose which is what I interpreted the question to be. The reasons I gave are the reasons I choose the roms I choose. I don't mean to speak for everyone, but that would be the most basic reason to choose a rom other than just to try out what is out there but we ultimately stick with certain roms due to what's included in the rom as well as the stability of it, although as stated before by more than just me, the ICS roms have the same bugs and therefor the same stability issues. Again, not trying to step on anyone's toes, I don't claim to speak for everyone, but I answered the question as I interpreted it.
Also, as to specific roms, I'd be here all day if I chose to speak on that because I started using custom roms on my old G1 and I've tried out probably over 100 roms for various phones over the last few years. For that matter, I could go way back to the days of the Motorola Razor and a few other phones out around the same time, but I was speaking more about android roms. As far as the roms is concerned I don't care if it's miui, ICS, AOKP, etc. If it has the features I'm looking for and is stable, then I use it until something comes around I like better.
I went with AOKP because
It had full source code and I could modify it as I wanted
I liked the layout of toggles
AOKP ROM Control had features I wanted
I could long-press Back to kill a process
It has "quiet hours"
It has decent control of background data use
I knew where the kernel came from and it has full source code
I knew where all binaries came from and it has full source code
I know the last two of these are an absolute requirement under GPL, but many ROM "authors" fail to provide this information.
AOKP has some "crap" that I freeze to improve performance, but I haven't run out of on-phone storage yet.
CyanogenMod 9, for me, wasn't quite as "usable" as AOKP, the way I use my phone.
MIUI is too "Technicolor" and gimmicky for me. Most of what it has (other than a decent File Explorer, when it doesn't crash) I consider "bloat."
SLIM seemed like a good candidate, but without easy access to full source and the ability to build as I desired, it wasn't on my short list. I tried Lightning or whatever its "default" launcher is, but it had a couple things that just didn't allow me to set up my phone the way I wanted (paging is "wonky" to the way I have come to think of a launcher).
Kernel -- Well, Hefe Kernel pretty clearly added what I wanted; better battery life without significant impact in responsiveness. I'm glad others find what works for me helping them out too.
The Zip-n-Go ROMs don't, in general, excite me. I'm not a big theme guy and I can add/remove what I want pretty easily myself.
@krazymonkeys
I understand your point. I also try everything and then stick to one ROM.
@eollie
Thanks bro.
@jeff
That's the best example of kind of answer I was looking for. Thanks!
I'm on Erik's MIUI 2.8.10.
I tried it because I like the UI: I like the notification bar and full screen toggles, I like the kill app back button feature, the task manager combined task killer home button and all the sys apps. It is super fast, lighweight and easy to use. It is stable and gives instant GPS lock.
Only problem is the battery consumption, but it's kernel related I believe.

@itzik2sh
I tried MIUI but it is too bright. Don't get me wrong. I like it a lot. But since we don't have Automatic Brightness, then it was a pain. Anyway, it's a great ROM and I think battery didn't drain more than it does on other ROMs. What I love most about MIUI is the phone and text's apps.
This is going to be a long post, but please bare with me. The reason for this post is too hopefully reduce the number of "Help me choose a rom" threads, as they seem to get posted quite frequently, and ask basically the same questions. So in this thread ill be going through some of the basics, as well as some highlights of each type of rom
Introduction
I wrote this thread in an effort to make things easier for "noobies" or "new users" whichever you'd like to call them, so that they can have a better understanding of what the various types of Rom's are out for the Galaxy SIII or may be out in the future. Here's a very common question, what is a rom? A rom on our android phones is like the operating system on your computer, it controls the user interface, what you see and what you can do. Thankfully we have developers who have taken the stock rom's and changed them up and made them 'better' so that we the users can unlock the full potential of our phones. In this thread i will do my best to give you a brief outline of what you can expect with the different types of roms, and what bugs you may encounter. What i will not do is make any claims as to what the 'best' rom is, or tell you what you should be running. I am simply going to give you the information that you need to better help understand what can be included with each rom type
***Disclaimer: Anything you do after reading this thread is on you, what you decide to flash or not to flash is on you. I am not to be held responsible for anything that you do to your phone. This is simply information to help guide you and teach you a few things about roms.***
What you won't find in this guide, but should familiarize yourself with:
These guides don't have to be read, but i highly recommend you at least glance over them to familiarize yourself with a few things, before flashing your first rom. They all contain important information that you should know

CHAPTER 1: Touchwiz Roms
***Based on samsung's touchwiz.
Section 1: Stock Rooted Roms
These roms are exactly how its said stock and rooted they are the OTA's that verizon puts out, the only difference is that they've been pre rooted for the rooted users who want to be rooted but just want that basic stock experience. They may come in two flavors: Odex and Deodex, the difference between the two is the way that applications (apk files) are packaged. Odex is the stock way, and Deodex is repackaged, if you're looking to make minor modifications or do a little themeing then you want Deodex because 99% of theme's are built for Deodexed ROMS. There isn't much to be said for stock rooted roms, you're going to get that stock experience that comes with the phone but with root capabilities (titanium backup, wifi tether, overclocking, etc)
-Is this for me? If you want that exact samsung touchwiz stock feel with nothing added in then yes this is for you.
Section 1A: Debloated Stock Rooted Roms
These roms are going to be "debloated" meaning most if not all the fat is taken out of them. In the SIII's case you're going to lose most of the samsung apps and verizon apps. With this you may also lose some of those touchwiz features (smart alert, direct call, etc) or verizon features (NFL mobile, my verizon, etc). The benefit? You're still going to be mostly stock, and you may notice a speed increase due to there being less fat in the rom. There are various levels of debloating as well, some are more extreme and have had everything removed except for the essentials, and some will only remove a few things. Its best to read the original post with each rom to have an idea of what has been removed.
-Is this for me? If you want the barebones experience without using AOSP the yes this is for you.
Section 2: Modified "Stock" Roms
These roms, are going to be the touchwiz rom's made for verizon phones, the base (what the rom is built on) will either come from OTA updates or from leaks. These roms are modified in someway, some more than others. The modifications can include a wide variety of things from the basic speed tweaks, enhancements, and themes to including custom kernels, removing the wifi notifications, extra toggles in the notification bar, 4 in 1 reboot menu, and many other things. They are in a sense stock, but at the same time not. Think of it as a developer taking something 'good' and making it 'great' they've added in the stuff that should have already been there from the start. They will generally be deodexed already, may or may not have been debloated to a point, and generally will have a lot of 'under the hood' enhancements.
-Is this for me? For most people this is for you. You'll have a lot of the touchwiz features that you've come to love such as the camera, smart alert, direct call, and other features, while also getting a much faster and generally better experience. You'll be able to flash themes easily (make sure to double check that the theme is compatible with your rom) root app's will work and you'll be happy.
Section 3: Leaked Roms
These roms, are built off of leaked builds/bases. They may be ICS, Jellybean, etc. These rom's generally may have bugs to begin with depending on the leak itself. Some leaks are a little more stable than others, generally the only time leaked builds have major bugs is when its a leak of the next android version (a leaked JB Touchwiz build for verizon) otherwise they'll generally be almost bug free. There isn't much to say about any leaks of the current version (SIII shipped with ICS Touchwiz) because those will generally just get merged into the custom builds and such. Leaks for future versions generally have bugs, some big, some small, but usually get worked out quickly depending on the bug.
Is this for me? If you're looking to get that future android feel before its official then yes its for you. But you have to be willing to accept that everything may or may not work, and may or may not get fixed before an official release happens. You'll have the latest and greatest though and be able to brag to you're friends about having it before they do.
Section 4: Ported Roms
These roms are ports, meaning they could come from a different carrier (Example: AT&T JB touchwiz on verizon), different manufacturer (Example: Sense 4.0 on SIII), etc. These rom's will almost certainly have bugs to begin with. They are in a way like leaked roms because they aren't "official" for the SIII, but also vastly different because they may not even be mean't for the SIII. These rom's generally require a lot of work to even get booted up because its based off something that's not even mean't for the verizon SIII and a lot of work goes into them. Bugs could range from little things like screen flickering to GPS being completely borked, to your phone not even booting up. After they've had some work hammered into them and testing done, they can be really functional as a daily driver.
Is this for me? If you're looking to have something different or the latest and greatest then yes its for you. But like i said with leaked rom's you have to be willing to accept that you may encounter a vast variety of bugs that may or may not get fixed quickly or at all depending on the bug.
CHAPTER 2: AOSP (Android Open Source Project) Roms
What you won't find in AOSP: Any touchwiz features, yes this includes the camera as well. This is because touchwiz features and apps require the touchwiz framework which is not in AOSP and probably never will be. You also will find that verizon apps tend to be hit or miss as well, most of the time they won't work either, yes this includes NFL mobile and My Verizon.
Known issues when going from ICS touchwiz to AOSP JB:
*GPS may not work correctly, the fix? Before flashing to AOSP JB make sure you have a full gps lock (i personally download gps status from the market and wait until almost all satellites are locked) then from in the app boot into recovery and do your usual wiping/flashing.
*NFC may not work correctly, the fix? Ensure NFC is turned on before flashing to AOSP JB (i personally don't use NFC so i can't comment on whether that works or not, but i've heard it does)
***Based on pure android, you won't have any kind of carrier/manufacturer features added in. If you've ever had a Nexus device then you'll know what this is.
***Themeing is also super simple, with AOSP you get the Theme chooser, which makes changing themes as simple as a few clicks, just download a theme chooser theme off the market and then go into theme chooser and apply it. It really is that simple, if you want to change back just apply the "system" theme, and bam you're back to normal
Section 1: CyanogenMod (CM)
The one's who started it out, they've been around for what feels like forever. This rom will be built straight from the latest source, and it'll be fast from the get go. You'll immediately notice that you've got a lot more RAM free off the bat and this is because there is absolutely no bloat in it at all. You'll have the pure google android experience, it'll be a love or hate thing. For CyanogenMod they generally have nightly builds for those who love to flash, and it'll have added in whatever they added/fixed for that day. These builds may be stable or may not be stable, today's nightly might suck while yesterday's was great. For these if you know what features the latest android version has most likely they'll be in CM, so if you stay up to date then you'll be good to go. Some features are added in though such as notification widgets/toggles, speed tweaks, various other shortcuts. They will generally keep it mostly stock android but also give you some treats that make it better. Bugs are hit or miss, especially for the SIII because pure AOSP android was not built for it originally so some things may be a little iffy (GPS, data, nfc, mms, call volume, etc) it doesn't mean they are all broken, but it's possible they are hit or miss at times, and you're miles may vary. For one person GPS might be fine and the other it could be broken.
Is this for me? If you're looking for that pure android experience without any manufacturer crap in it then yes its for you. Just know that you may encounter bugs that don't get worked out right away, some of them take time.
Section 1A: Unofficial CM Builds
These builds are based off of CM but they are unofficial because a developer wants to make nightly changes, and add in there own modifications, themes, fixes, enhancements, etc. They come with the same risk as official CM builds, but any bugs found in them should not be reported to the official CM bug tracker because then these are unofficial builds. There isn't anything wrong with them being unofficial, its just a developer wanting to add there own twist to the CM builds.
Is this for me? If you're looking for that pure android experience without any manufacturer crap in it then yes its for you. Just know that you may encounter bugs that don't get worked out right away, some of them take time. Please read the OP's thread to understand what changes they have added in.
Section 2: Android Open Kang Project (AOKP)
Almost just like CM but with a little more added in. Its based off the android source code and again won't have any manufacturer crap added in. With AOKP you'll get added in modifications that may not be found in CM, as well as other kinds of toggles, status bar mods, notification mods, etc. I can't say everything because its still based of android source and comes with the same risk as CM which is certain bugs or things not working (GPS, data, nfc, mms, call volume, etc) They know there stuff though and have "Builds" released from anywhere from day to day or weeks apart these builds are more major releases with various fixes, modifications, etc.
Is this for me? If you're looking for that pure android experience without any manufacturer crap in it, and more modifications than CM then yes its for you. Just know that you may encounter bugs that don't get worked out right away, some of them take time.
Section 2A: Unofficial AOKP Builds
These builds are based of off AOKP but they are unofficial because a developer wants to make there own changes, and add in there own modifications, themes, fixes, enhancements, etc. They come with the same risk as official AOKP builds, but any bugs found in them should not be reported to the official AOKP bug tracker because then these are unofficial builds. There isn't anything wrong with them being unofficial, its just a developer wanting to add there own twist to the AOKP builds.
Is this for me? If you're looking for that pure android experience without any manufacturer crap in it, and more modifications than CM then yes its for you. Just know that you may encounter bugs that don't get worked out right away, some of them take time. Make sure to read the OP to understand what has been changed in the build though.
Section 3: Paranoid Android
This rom is a phone/tablet hybrid rom. Its based off of pure android source just like CM, but has made vast changes to it. You'll be able to modify how each specific app shows up on the screen (want tablet mode only for youtube then you got it, want facebook to look bigger or smaller then you got it) and you'll get a wide variety of modifications as well. If you've ever watched a video of a tablet then you'll have an idea of what can happen. It truly is a phone and tablet hybrid, bringing the best of both worlds to your phone. It'll feel like pure android source and will have those features that come with that android version just with the tabletness added in. It comes with same possibility of bugs as other AOSP roms (GPS, data, nfc, mms, call volume, etc) these bugs are not guaranteed and may or may not occur. User A might have data issues but user B may not, your miles may vary with AOSP. Its a bit harder to explain everything for this rom, but i'm doing my best.
Is this for me? If your looking for pure android goodness but with a major overhaul of added in phone/tablet mode hybrid then yes its for you. Just be willing to accept that you may encounter bugs along the way.
Section 4: Other AOSP Roms
The reason i have this section is because its impossible to describe every kind of AOSP roms, especially when more can be added and such. But other AOSP rom's will come with the same pure android source as well, and will have those features. A lot of them merge in code from other various developers (with permission of course) but also add in there own toolkits, setting menus, etc. They are all great roms, but its hard to give every single one a section because its there all based off the same source and have some of the same kind of modifications added in. They all come with the same risk as other AOSP roms in terms of bugs (GPS, data, nfc, mms, call volume, etc) For these rom's you'll have to pick and choose, if you love a certain developer that makes AOSP roms, or have used a developers AOSP rom on a different phone then you'll know what to expect from that rom/developer. Again there is nothing wrong with these rom's its just hard to give all them all there own section when most of the information is going to be the same and repetitive.
Is this for me? If you're looking for that pure android experience without any manufacturer crap in it then yes its for you. If you follow a specific developer then yes its for you. Its going to have more modifications then regular CM or AOSP roms. You really have to test them out for yourself, just read the thread and see what they've changed/modified/added in. Just know that you may encounter bugs that don't get worked out right away, some of them take time.
Section 5: MIUI Rom
Miui is AOSP based but it won't look like it is. This is because with MIUI you get an entire different user interface experience. It's got its own custom toggles in the notification pulldown, its own theme engine (theme's have to be designed specifically for miui), its own camera app, and many other apps that are designed specifically for it. The main miui team puts out a rom in chinese once a week every friday, and it then gets ported to various devices including the SIII. The downside to miui is some things take a lot longer to get worked out in terms of bugs, this is because its ported to our phone but also because its a completely different interface with many applications that have to be worked on before they'll work flawlessly. Its got the same possibility of bugs as other AOSP roms. I've personally used it before on another device and ill tell you its definitely one of a kind, and fun to play with.
Is this for me? If you're looking for something completely and totally different then yes this is for you. Just know that because the larger builds are released once a week it may take time for some bugs to get worked out, but again you'll have something that's completely different from any of your friends as long as you can accept a few bugs here and there.
Section 6: Various Issues and Solutions
NFC Issues: Grayed out, won't turn on, etc. This is NOT a problem with rom itself, to solve this issue you will need to go back to a touchwiz rom and turn NFC on. Then boot into recovery and flash your respective rom choice If that still does not work flash this zip here in recovery after flashing your respective rom.
GPS Issues: Again not Rom related entirely, its more or less AOSP related. This problem again can be avoided by ensuring a full gps lock and leaving gps turned on prior to flashing. If you still have issues after that download GPS status from the market and use that to help with the gps lock. You can also flash this zip file here to help solve the issue
CHAPTER 3: Kernels/Battery life/Radios/Jelly Bean 4.2 Storage System
Section 1: Kernels
Okay kernels are one of the biggest advantages to rooting. They can be used to increase performance vastly, increase your battery life, make your phone faster, increase ram, etc. You can modify the clock speeds using apps to overclock or underclock the cpu, you can increase or decrease the voltage, etc. They are also what makes your phone boot up (flash a kernel mean't for touchwiz on AOSP and its not going to boot up) Kernels are built on two main bases for the SIII: Android Version (ICS, JB, etc) and Touchwiz/AOSP. This means that these kernels are used for specific rom bases and android versions. You have to make sure you read what the specific kernel is built for so you don't flash the wrong one and mess up your phone. Kernels are always your miles may vary, a kernel that works great for me and doubles my battery life, might make yours worse. You really can't guarantee any of that until you flash it on and modify the settings to your liking. Always make a backup before flashing a kernel so just incase your phone doesn't bootup you can easily restore the backup.
Section 2: Battery Life
This is another question i see asked all the time "What's the battery life like?" Battery life is based on a few things:
1. ROM Choice - Some roms might have better battery life than others. Your miles again will vary. You'll never get the same experience as another user.
2. Kernel choice and settings - some kernels work better than others in terms of battery life, what works for you may not work for me. But you can modify your cpu speed settings to help with this. Settings screen off profiles can help as well. I personally decrease the cpu to 384mhz while the screen is off, and it helps me, will it help you? I have no idea.
3. Personal Use - Self explanatory, if you're constantly using your phone, browsing the web, sending emails, playing music, gps, this and that then the battery might drain faster than somebody who doesn't use there phone as much. If you manage to get 3-4+ hours of screen on time then your battery life is fine. How quickly you reach that is based on your use. This also includes whether your still on the stock battery or not, if you've got an extended battery in your phone then your battery life may very well be a lot longer than somebody with the stock battery. You have full control over your personal use.
4. Coverage and Signal - If you're constantly in areas with terrible signal then your battery life will suffer. My suggestion? If you're near wifi turn it on, that way your signal won't matter as much because all your syncing and such will be done through wifi. There isn't much a rom or kernel developer can do about this, its just based on where you live.
5. Wakelocks and syncing - Make sure to download betterbatterystats, why? Because if your battery life sucks then your phone may not be going into deep sleep and this app can help tell you why. Wakelocks are anytime that your phone is awaken from deep sleep, the more wakelocks you have the less deep sleep you get which equals less battery life. Some of these wakelocks can be controlled because many are caused by syncing. If you have apps syncing every 10 minutes, don't expect super great battery life because your phone is constantly being awaken. Control your syncing, if you don't check twitter every 10 minutes then don't have it sync every 10 minutes. A lot of those apps will automatically sync upon being started.
6. Perception - I put this here because its true. Everybody expects something different with there battery life, so they perceive it that way. Some users want over 24 hours whereas some don't. For me personally i consider great battery life to be being able to leave for work at 6:45am, then go to class, then go to the gym, then do whatever else and come home. If i can make it from 6:45am to 8 or 9pm without being forced to charge then i consider that great battery life. Why do you say its great when its only 14 hours without charging? Because i charge my phone every night before going to bed, it may not even be less than 50% less but i still charge it so that's good enough for me since i made it through my day. Everybody has different expectations so don't always assume battery life sucks when somebody says it does because its based on there own perception of what's "great" and what's "bad"
Battery life is and always will be your miles may vary because there are just too many factors to consider. Some people who say "The battery life on this rom sucks" just have a runaway app killing there battery life and don't even realize it. The only true way to gauge battery is based on what you consider to be great battery life.
Section 3: Radios
Another question asked "What's the best radio?" Radios are always your miles may vary, its all based on your signal/coverage area. But there's also a big placebo effect that comes with radios, the second you flash a new radio, you expect the signal to be better so you see it that way. It might actually be better or it could be worse or exactly the same. Some users will get increased speed on one radio and somebody else might get decreased speed, but you can't base your radio stats right after flashing it because you need to test it in real world scenarios, not just sitting around looking at the dbm. I didn't originally plan on having this section but its necessary because in the future you may or may not need a specific radio for a specific rom to work. As of right now (10/22/2012) the radio you choose to use will work on any rom (make sure its a verizon radio) in the future though you may have to use specific radios for specific roms depending on the versions of android that come out, and when that happens you'll have to make sure you're using the right radio otherwise you may not get any kind of signal at all. Remember that radios are mostly user experience based, and what works for you might not work as well for somebody else.
Section 4: Jelly Bean 4.2 Storage System
Alright i'm going to do my best to explain this in the simplest way possible. With the introduction of 4.2 Jelly Bean, the storage/file system changed as well. What i mean by this is at least on AOSP roms when you flash a 4.2 Rom you'll get a "0" (zero) folder with everything from your internal SD card in it. The reason for this is because with the multi user support its the new way Android sorts stuff. Now many of you are probably wondering "Ummm... this is confusing" or "is this bad?" it is confusing at first but honestly its not that bad. The /storage/sdcard0 now points to /storage/emulater/legacy folder which is then emulated by the 0 folder. Easy version: Even if you put stuff in /storage/sdcard0 it'll automatically show up in those other folders anyways. It may look like you've got stuff duplicated, but its really not. Whatever file is on the sdcard0 (Internal card) is only there once.
The good news, if you update your recoveries to the latest versions, then you won't have to worry about any 0 folder nonsense anyways. You'll still have a legacy folder, but that's not a big deal. Just don't mess with it and your phone will be fine.
***If anybody has a better explanation for that, PLEASE let me know and i'll update/add it in ***
I really hope that this thread can help reduce the number of questions asked about which rom to use and such. I put a lot of time into typing all of this out to help you guys, so hopefully it'll do just that and help
Also i spent a lot of time writing this up, so please do not copy and paste it on another forum and claim it as your own work. I realize its just a guide and relatively public information, but still i'd rather it not get copied and pasted onto other forums/threads.

I was just thinking we really needed a single source to track the progress of each ROM category. This makes a great framework for tracking that information. Thanks for putting this together.
My suggestion would be to add a few bullets below each ROM category that note the most prominent long-term bugs. I think that could significantly reduce the same question being asked over and over within each topic.
Example: all of the AOSP 4.1.x ROMs currently suffer from low video recording volume, poor voice command recognition, and limited in-call volume range (as of this post). Just a suggestion. Keep up the good work!

After thinking about this concept more, a community-maintained wiki might actually be a better medium for efforts like this. Ensuring accuracy, keeping everything up to date - and remaining relevant as a result - always seems to be the greatest challenge.
This thread was well over due. Thanks for taking the time to write it up.

mhmmm. Thats why i tried to keep this as "basic" as possible and just going over the general stuff. I'm able to keep up with a lot but only to a certain extent.

True. Fortunately, the ROM categories themselves are fairly constant, so this thread should be pretty low maintenance. Hopefully it will get stickied or merged with a stickied thread so it remains visible to noobs.

Yeah thankfully they are I've just got a few more things to add and a little cleaning to do with this thread.
great writeup...this needs merged with the download list thread.
