Custom ROM vs Stock One UI ROM - Samsung Galaxy S9 Questions & Answers

Hi, I'm thinking about installing a custom ROM. Could anyone here please give me a summary of how much it's better compared to the stock One UI ROM? If it's better at all, of course. Especially in terms of battery life.
Many thanks!

might been a late reply but ofcourse a customized custom rom will have better battery life and some other benefits ...

[Q] Which ROM for best battery life but w stock Sense feel (for the wife's phone!)?

Hi,
I'd appreciate some advice (having searched as best I can first, and without hijacking another thread) - I'm a Nexus One user (running CM6.1, and very happy with it), but my wife's Desire (currently unrooted stock latest OTA update) has a sucky habit of running the battery down to zero every so often when she's not using it and I've been thinking a custom ROM is the way to go. However, there's a lot of roms for the desire, and I can't work out which meets the requirements best:
1) Must appear to be a stock Sense rom to the user (she's just got used to the UI, and I don't want her to get flustered) - I'd like something that seems as much like the stock rom as possible please.
2) Best possible battery life (happy to try uv if it's unobtrusive)
Any replies very much welcome, ta.

I prefer not to say which ROM is better compared to other ROMs as I think it would be unfair on the developers who have put in so much hard work to bring us such a great variety of ROMs, but in terms of battery life, I would personally say that I had the best battery performance out of OpenDesire. The only problem though is that OpenDesire does not have Sense UI. With it, I was averaging about 2-3 days (depending on usage) use out of it before I need to put it on the charger. At that time, I was also running a different Radio (5.10.05.23).
If you really need Sense UI, then I would suggest LeeDroid's ROM as it provides pretty good battery life as well.
Have you considered the MIUI ROMs? they are pretty new and highly customisable, with an iOS like interface with widgets, also provide impressive battery life and are very stable.
I'm sure many would disagree with my findings but this is just based on my own experience of using these ROMs.
MasDroid,
Many thanks for the advice - I've gone with LeeDroid and it's worked like a charm. A well supported and stable ROM, which I'll recommend to anyone in the same position.
Thanks again!

I second MasDroid's opinion about LeeDroid ROM.
I am glad you're enjoying such a good ROM. Hope your wife is happy, i know how important that is

[Q] Best autonomy between froyo/Miui and Gingerbread roms

hi it's again me i have a simple question to ask you wich rom has the best battery autonomy using sense 2.1 ! gingerbread? Miui? or froyo please tell me what's the best thank you veryy much guys
No way to tell.. You'll need to try them out and find the ones you like/find least battery consuming.
I've seen plenty of people trying to compare battery life on different roms based on anything from feeling to sleep voltage numbers to screen battery consumption, and it just isn't anything to go by.. The numbers are completely random from device to device and from user to user(depending on how you use the device), so no there is no one great/low battery consumption rom EOS
I'll suggest oxygen as a nice and lightweight aosp rom, but try different ones out
In my opinion, Gingerbread(Android 2.3.x) Roms must be much better than Froyo(Android 2.2.x) Roms. And if you are looking for the Rom with the best battery, I may tell you that Miui is you last choice...

New user here, interested in rooted stock ROM, looking for stability and battery life

So, any recommendations?
Yes...try different roms and kernels and keep the one that fits you the most !

Best Rom for Battery Life/ Camera/ Performance

Hi, i've a Lg g3 with Fulmics Rom, i'm really happy with it but the battery life is terrible. Before upgrading to Fulmics Rom i was stuck on CloudyG3, i switch between roms every time with a clean install. I really like Marshmallow but switching back to Lollipop wouldnt be a problem. So, for Battery Life, Performance and Camera what is the best rom? Thanks for the support and sorry for the noobish question, i know that there isn't a best rom in absolute, but i'm here to hear the advices for your personal experience.

Thinking of using a custom ROM?

Hello guys! I'm currently on OxygenOS 3.5.2 Community Build and the battery life sucks! I'm wondering if I should switch to a custom ROM + kernel, and if I should, which combination is the best?
There are so many options to choose from and it is very confusing.
1. What ROMs are suggested for best battery life?
2. Which kernel is suggested for best battery life?
3. What is the difference between the FreedomOS based on Stable and Community Build? Which is better?
4. How's the battery life of FreedomOS like?
5. What are some bugs that I should look out for?
I'm kind of leaning towards OxygenOS based ROMs for the stock camera quality. Is there anyway that the other non-OxygenOS based ROMS can achieve similar or equal quality?
I hope you experts can assist me, kind of new to this device and the custom ROM/kernel scene.
Thanks!
NucleaROM has the best battery life, it is smoother than any other ROM I have tried, it has the OOS camera port availability etc.
The $1m question, there is no one answer to this. Best advice would be to try out ROMs for yourself, personally I would stick with the kernel provided with the rom as once you start mixing and matching the chances of hitting the best combo for your unique usage becomes less and less.
Two bits of hard advice though, 1. Backup your current rom before starting and transfer the backup to a pc. 2. Judging battery life of a new rom is a lengthy process so give it a good 3-4 days for your usage pattern to settle down before passing judgement on the expected battery life.
