From ICS to JB - any advantages?

I was just wondering what the experience has been for people who switched from ICS to JB. Are there any advantages in terms of battery life, stability and/or performance?
Thanks in advance.

Better Performance (Projekt Butter)
New Statusbar

Google Voice is now offline usable I think.
There're more changes but I don't know exactly

I'm using TAJB rom from last 1 month, it is daily driver with very minor issues and 100% faster smoother than any ICS rom.
I can say JB is real matured OS of android.
For example, Max Payne game
On ICS it strucks very much, and need to wait almost 5 mins to load the game. I know saving the game also an issue.
On JB, it is smoother and loading became very faster and never strucked. i tried very hard to struck it intentionally but failed every time.

Praveen.

I understood that there is a better performance, but is there stability for every day use and not only? I mean, is there an JB ROM with the perfect stability of a stock ROM for SGS?

There is no perfectly stable JB roms atm as they are all still in alpha/beta.
Elite's recent beta 9 is apparently a very good improvement over beta 8, some are even claiming that it's currently better than his very good ICS rom.

What do you believe, could JB get more improved for SGS than ICS? I mean, all of the ICS rom's that the developer said that are stable, failed at some point. Every ICS ROM that I had on my phone, had a critical point in time where all of the apps and system apps had permanent FCs so I'm looking in the close future for a ROM that it isn't stable for an "determined" period of time... I know that it's not necessarily to get better stability while having better performance, but I hope that there is a better chance in improving our SGSs with JB.

The FCs you got is probably because your /datadata partition got full. Install the Datafix app from the Play Store and clear your cache every now and and it shouldn't happen again.
I've used Elite's ICS rom since beta 10.1 and it's been stable as a rock for me. I'm sure his JB rom is just as good.

Hey guys, I am still using an odexed version of GB, it is very fast and stable but does the memory improve in ICS or JB, the problem with the sgs as you know is the memory I just want to know if ICS or JB use less memory then GB.
do you recommend to change?

For me battery life was a bit better on JB, depends really on the kernal you use though,
with performance, depends on the ROM you are using, for example i found that some roms where slow, and had poor battery life, while others were extremely fast and had good battery life.
Im currently using X-bean 1.0 and i am very happy with it

Hmmm...
I tried several JB roms and in my feelings JB boot much longer, maybe something is wrong with my phone ? :crying:

The current best one is X-Bean. I've tried all of them and X-Bean is by far the most usable rom that is available currently, with SlimBean + DevilKernal combo coming in second.

In my experience, boot times vary from rom to rom even within the same android version, with lighter roms having shorter boot times.

Same here, I'm using X-Bean and since now the fastest and most stable JB ROM (I used all JB's on XDA). I'm using Devils kernel and in normal usage - 1,5 day. Best battery of course on GB, but this is a small cost for performance

Stock rom vs AOSP roms

Hi! Right now i'm using stock, i am pretty happy with it smoothness is good and battery life is around 4-5 hours of SOT with undeclock at 1ghz. I want to try some kitkat based aosp custom roms, but i don't know how good they are. I only tried android 5.0 but the battery was draining fast, so... with AOSP roms i will get better smoothness and battery life? I'd like to try them all but i don't have time and a working computer. What rom do you recommend?

Stock 5.1.1 is the best right now. Latest version and very stable. Great battery life too. I used to flash a lot of custom ROMs, but now stock with root seems good enough

I downgraded from 5.1.2 to 4.4.4 108 and am having a lot of fun
The phome is more responsive
More stable
Better battery life
Better camera quality
Less bugs
More mods and tweaks
The only cons is its not smooth like android lollipop
If u didnt use lollipop before, u wont notice the little stutter on kitkat

I use 5.0 stock rom. Its smooth everything is fine. But camera is not much clear and bettery life is around 4 to 5 hours.. What is yous bettery life??

Should i flash a custom rom?

Hello, so I'm asking if I should flash a custom ROM instead of keeping my OOS 4.1.3?

U have to try man. It's clear thing for this device.

One of available versions of RR, phoenix AEX, official AEX, Dirty Unicorns. Today im back to Phoenix AEX, it is a great, stable and fast rom with great developer.

This is so vague, as it tells us nothing about what features you may be looking for, why you want a custom ROM, etc.
If you are just looking for something different, then sure, go for it. Similarly, if certain features of a custom ROM (or ROMs) look attractive, then go for it. There is really no downside, as unlocking the bootloader does not void the warranty. And reversing any changes (returning to stock) is pretty easy as well.
On the other hand, stock OOS is amazingly good. Very little bloat or skinning, but with the right amount (IMO) of customization added. Many folks (myself included) accustomed to flashing custom ROMs to get the most out of their device, have been just happy with stock OOS. But of course, there is always room for improvement, tweaking, etc.
It's an individual choice. Most users of Android devices will never flash a custom ROM. Majority probably don't even know what that means.

First determine what you`re missing in stock OOS, find those features in a custom rom/kernel and flash it. Done

Its not just a rom or kernel that makes great batterylife, mobile reception strenght (modem ) and usage (apps, syncing, gaming yes or no) are vital too.

I'd go with FreedomOS or RRemix. Really LineageOS is mostly placebo battery fixes and an overabundance of customization options. Most of the lineage roms outside of RRemix are very unstable or just kinda useless. Hate to say it cuz some devs put lots of time in but Ive always found worse battery life with the same usage patterns on anything but stock.

Oh. That's bad. I want to use a custom ROM. But if Oxygen is so much better?!?!? :silly:
No good ROM available?

Well Oxygen OS was made for this specific phone in mind remember. So of course it fares best.

I don't know. Perhaps lineage with sultan kernel is an option.
I try to find the best ROM with great battery life, performance, stability, features etc. Any recommendations?
Phoenix is good, Resurrection remix also, but how is battery life and performance? So many features in it...

In the time you've been waiting around for someone to make a decision for you; you could have just unlocked the bootloader and flashed a ROM (of even more than one) and be trying it yourself.
Just make a TWRP backup of the stock ROM (or otherwise, know how to return to stock with the official zip file) and you can easily revert if you don't like the ROM you flashed.
No point in waiting for someone else to tell you what to do. Everyone's opinion and preference is going to be different. Just because someone tells you to flash a ROM or not (or which one), doesn't mean that is the right answer for you as an individual.
Even things like battery life and performance are going to vary drastically depending on how you as an individual use your device (as others have also mentioned). Then also throw in the differences in personal preferences and tastes; and the result is that you can't go by the direction of others. You need to decide for yourself.

Thanks. I already tried some ROMs. But I can't decide.
Are there big differences in battery life?

Plus others (more than one) on this thread have already answered the question (of battery life on the various ROMs).

You're right. It's only so difficult to decide, because here are so many ROMs and kernels and they are all similar and I want a good daily driver and don't want to change it the next years.

I will try lineage with sultanxda kernel. I hear it has amazing battery life.
I also like Resurrection Remix , but I suppose, it has bad battery life, but I'm not sure.

I've tried a handful of roms... they're all just fine in my opinion but I seem to always end up back on the Oxygen stock rom. I root, but that's about it. I just can't get over how well Oxygen OS is running these days compared to my OP2 ... Just flash and try! You won't hurt anything, and if you do you have a 99% chance of fixing it!

Stable Rom??

Hi so I installed RR on my mums s3 mini, it lags a lot and the wifi never autoconnects so she has to reboot the phone very often
Im looking for a rom which battery lasts enough, decent performance (she doesnt use performance demanding apps) and overall stability
Android version doesnt matter

Omni rom, but don't expect battery miracles with those 1500 mAh.

My girlfried uses CM12.1 from novafusion and it works without any problem. Battery is excellent.

I tried several Roma but only those kikat were stable .. :crying:

This ROM is really great!

Guys, what about those new ROMs - RROS 5.8.3 or LOS 14.1? Are they stable enough or are the older ones better?

This is a good question. I use old cm11 Om S3 mini nfc version
But i think about upgrade. Is there any stable custom for everyday use?
I mean not alpha or testing version.
I need stable Rom for this phone. Any help?

I have used this rom for a long time without any problems. Its battery life was very good and performance is better than the other Lp roms. You can use it. or you can use omni kitkat. its performance was amazing but its battery life is not enough. I will change the battery and flash omni kitkat again. I was really amazed
