I don't think it's bad unless it affects your offline life.
On a serious note, even I was wondering if flashing different roms(flashoholic that I have become) has a negative effect on phone/memory/sdcard/ram/processor/battery/etc life.

I also want to know this... will flashing make your ram less?
or how about... will always doing factory reset will make your ram (or any memory) less?

I myself flash 2-3 ROM's everyday. I think my battery life has decreased somehow .

I flashed a new rom/kernel whenever its available and it suits me. Otherwise, I'll be trying out initd scripts or mods.. It's battery life also had depreciated much. While owning the i9003 for over 2 years, I've gotten the Nexus 7 and 10. I now prefer Nexus's development because only Nexus can get the latest development and you get to enjoy all the developments from big names like Trinity, Franco, Faux, Motley, Rasbeanjelly, AOKP (pub edition), CarbonRom and many more.. To ROM/kernel junkies, you must own a Nexus at least once in your lifetime, no regrets... I highly recommend it...

How fast are custom roms on the GS3?

IMO the stock phone is extremely fast and smooth. With 2GB ram I also haven't seen any apps being forced out of memory.
So with a custom rom, all the speed tweaks etc, what exactly is improved over the stock phone. Do apps launch faster, less lag etc? Are there any videos comparing stock vs custom (esp AOSP vs TW) ?

I personally just used AOSP for about a day, switched back due to a few bugs, but it was definitely speedy quick. Faster than stock? Yes for sure, but stock is super fast as it is. As for AOSP vs TW, i'd love to stay on AOSP but i love the TW camera and just can't get over not having it You should try custom roms for each one and just see what you prefer

If you look on YouTube you will find several reviews on roms currently available for our gs3.

At this point in time they offer no advantage over stock. Hopefully one day they will but Samsung did such a great job on the stock Rom for a change that our custom roms are a little faster but with a few things broke or bad battery life or bad 3g/4g hand off.

I agree 100%.
I have tried every ROM available at this point & I always end up going back to the setup in my sig.
I always chuckle when I read post claiming a ROM is smoother/faster/less lag etc than a completely debloated stock ROM like CleanROM or Synergy. Talk about the ultimate placebo affect......

Most have issues but many offer huge advantages from deep functionality to deep customization. If those interest you, perhaps small issues in stability or data usage are a worthwhile tradeoff. Not to mention that the simple fact that you CAN do such a thing is a very fun and educational experience about what is special with android.
Also, debloated, over clocked TouchWiz Roms like CleanRom are faster and able to be set up for greater battery savings. Without question. It's a large field! Have fun by doing, you can always go back without cost!

The title of the thread was "...how fast..." I've posted on this before. Can we humans detect the subtle differences? Are the new roms simply a placebo effect of speed? I don't know.
What I look to are facts. The only facts we can use in comparing roms are the benchmarking tools. I have tried many different roms...Incu's, Slim's, Synergy's, Phantom, etc.....I have recently been flashing the Incubus Jellywiz roms pretty regularly, but got frustrated with some of the bugs ( more on these later ). So I went and retried the latest Slim and Synergy.
I can say. There was a perceptable difference between Slim/Synergy vs. Jellywiz. So I did a benchmark test. I tested each rom under pretty much the same conditions.
1. Flash the latest.
2. Disable the same Allshare/Samsung crap.
3. Load all my apps using Titanium.
4. Let the Rom settle for a most of the day
5. Test in the evening
No Overclocking...No other special changes.
I tested Using Antutu and Quandrant Standard....Slim and Synergy were about the same...in the high 4k's...around 4800 Antutu. Incubus' Jellywiz is always around 7800. Slim/Synergy was around 4800 in Quadrant, Jellywiz is consistantly up near 6000.
There are trade-offs / bugs / features....but...if you're looking for speed, I don't think you can find anything faster that Jellywiz.
The latest Custom has a custom overclocking kernal....for fun I bumped it up to 1800mhz and ran a 9500 Antutu. right now I'm running 192min 1200max and still pull a 7200 antutu score.
You pick:
> Speed = Jellywiz
< Bugs = Custom stock
My $0.02

CleanRom 2.1 with the CleanKernel 1.2 runs excellent for me, no problems, definitely quicker than stock, very smooth.

Getting a g3 a few questions

I'm grabbing one for my daughter today and she is going to want me to root, and flash a custom rom.
How stable is 4.2 and 4.3?
What roms/kernel combinations give the best battery life?
It's been a long time since I've used Odin "I think it was my galaxy s4g" since I've used it. The YouTube video under the how to post makes it look pretty easy.

4.2 is pretty stable, although the trade off is shaky WiFi to 3g to 4g hand offs.. Its pretty much the same for 4.3 ROMs as well.. 4.2 is a little more polished compared to some of the small bugs that still are being worked out in 4.3 ... Both are 100% better then touchwiz IMHO. Hope that helps.

Just use the stock kernals that come packed in cm 4.2 or 4.3.. And battery like in 4.2 is on par if not better than stock touchwiz.. 4.3 has a bit to go in that category

What you're asking is a very subjective question. I'd say most of the roms are nice to run and it really matters what features you and your daughter are looking for. AOSP offers a pure Google experience, but you're missing out on some great features touchwiz has to offer. There are good things associated with both options that might weigh you to one side or another.
Basically, I think factors that affect battery life the most aren't rom and kernel related, but applications running on your phone. I find any custom kernel you run will operate more efficiently than a stock kernel. You may notice a slight increase in battery life, but you'll definitely notice a boost in performance.
I'd recommend not relying on what people tell you are good roms, because everyone is going to have a different experience as to which is the best, you're basically going to get a bunch of answers to the same question. Even though our phones are the same, minor hardware and cpu differences could make one rom spectacular on one phone, and cause lag and frustration on another. Trying out roms and playing with them is part of the experience of finding the perfect balance between battery life and performance for your phone.
Odin is extremely easy to use, just follow the directions exactly as stated and you shouldn't have any issues.

I understand what you're saying I know with my phone Franco kernel only runs one core when the phone is a sleep and two with the ui and trinity is full performance. I wasn't sure if there was something like that here.
How stable stuff is really isn't a opinion.

You have a good premise, but stability is also linked to user error most of the time, unless you're talking about AOSP nightlies. If someone tells you they had a horrible experience on a certain rom, it's hard to take their word for it because you have no idea what other modifications they made to a rom, or if they followed flashing procedures correctly. It's not fair to the developer of a rom to have somebody who messed up their phone talk badly about it. It steers away a potential user from a rom choice and frustrates developers who put countless hours into their rom.
As far as your kernel question goes, I would look at the governor options available as that's what controls your cpu. You can gear any kernel to be more efficient or battery friendly with an app like set cpu. Ktoonsez and zues kernel have many governor choices available, as lean kernel would be much more stock like, but leaner. A governor such as pegasusq will control both your cores and only turn your second on if needed.

[Q] Stock VS AOSP

Hey all, I've currently got the standard Tab 2 and I was gonna wipe it and I was wondering if it would be worth flashing a aosp rom instead of stock. Is there much of a speed difference?

Definitely. For me stock was laggy and very slow. CyanogenMod (and other AOSP based roms) are very fast.
If you're only using your tablet for Internet, Email & Candy Crush. Stock is ok. But if you want to tweak and play high end games you should definitely consider using a AOSP rom.

That's pretty much what I was expecting to hear. I wanna start using it for note taking and stuff so I might just root and install an AOSP. What rom would you recommend?

Aosp ROMs are much better, fewer bloatwares, improved kernels, smoother ROM - you can even over clock your processor and all in all, more control over your device

AOSP :good:

since our device P3100 doesnt have much RAM and Processor is only 1GHz I recommend u try AOSP rom.
They are v.fast and there are many options to customize it as per needs.

[Q] Stock + GB or ROM?

Hi guys,
Thanks for all your help so far! Love this forum.
I'm pretty noob when it comes to Android customization, so I wanted your opinion: I'm trying to decide whether to run a stable, fast ROM, or simply stock with GravityBox and Franco Kernel.
Here are my considerations:
I'm not an advanced user, but I do use my phone a lot for work and personal things like email, browser, gps, videos, etc. Since I rely on it a lot, stability is pretty key. However, I get really bothered by some UI restrictions on stock (in particular non-customizable Quick Settings, non-customizable status/nav bars, and no PIE, but other small things count too). GravityBox is sufficient for the customization I need, but at this point speed and battery life come into consideration also. I wouldn't mind a longer battery since I use the phone pretty heavily. Speed is a consideration in that it would help me get things done faster.
So I guess my dilemma is whether I should use stock while relying on GB for customization and Franco kernel for battery efficiency, or if I should run a stable, fast ROM like SlimKat for the same purposes?

Xposed will slow things down so IMHO if a ROM has all your needs, use that.
That said I use a ROM and xposed

Yep, SlimKat, If stock Slim is missing a feature, about 50 people in that thread build their own Slim with some mods. One guy builds a version that has a DL/UL speed indication, L-style navbar buttons, and a bunch of other things.
Kernel, use Code_Blue. I prefer it over Franco. Just don't use the stock Slim kernel.

I'll add my usual comment..... Lol
Roms have near nothing to do with battery life. It's setup and usage that make or break battery life.
Don't factor battery life into Rom decisions.... They're all the same. ?

The only way a ROM can really affect battery is if a feature is designed poorly or there's a derp in the build..
But yeah, you can't really improve "ROM battery life", you can only make sure there aren't any problems which affect it negatively.

Really? I have the stock ROM and xposed with six different modules and I haven't noticed a substantial performance difference. Perhaps it's one of the modules you have installed or maybe xposed doesn't play as well with your ROM as it does with stock?

Xposed is always going to slow it down. The amount, however, is different for everyone.

So what about things like Franco Kernel, which claims to slow down processor when not in use to conserve battery?
And thanks for the help guys. I flashed SlimKat for now and am so far pretty happy with it.

Might not be noticeable, or it might be obvious, it's still always going to slow it down overall. Different experience between different people.

I've used every Rom and kernel almost and after setting each up how I regularly do, and with similar usage patterns always....my battery times were always similar.
I never play with the clock speeds I should add......but that's my experience. The roms or kernels I used made no real difference to my battery life.
?
Yes I've seen lots of "claims"....And guess what, many believe them. ?
