Best ROM for Battery Life and Stability for i9300? - Galaxy S III Q&A, Help & Troubleshooting

Hey guys,
I have 4.3 Jellybean for my Intl Samsung GS3 and battery life is downright terrible. I have it rooted and I am looking for a ROM. My main priorities are battery life and stability. I don't care about performance. Ideally, I want at least 3 hours SOT and all the functions work like stock firmware.
Thanks!

I suggest you to buy a new battery and keep using stock firmware.

Hi
I suggest you AMCHA Rom KK v 9.00 when use kernel ( MoRoKernel-1.7) : Battery Life awesome
or CyanogenMod 12.1 for i9300

I think it's your battery. I can easily reach 3 hours SOT and sometimes 4 ~ 5 hours SOT if im not playing games with my S3 on any ROMs. From Stock 4.3 to Custom 6.0

[Q] Battery life STOCK vs CM10.1

Hi, just wanted to know if i have the same application, the same usage with CM 10.1 and Stock lastest Sammy rom, which would give me more battery life ? :angel:
How much aproximatively would it be different if so ?
Samsung would be better.....10-20%
I keep reading of people using the phone while browsing for +4h of screen or surfing the web for 2h on 4G and still having 70% left of battery life.
This is all stock ROMs. From my usage this would be impossible, I'm using cm10.1 and on 3g I could probably go to 2h screen on but that's it.
I'm starting to think that maybe aosp roms don't even come close to stock ROMs (which I never tried though).
Some experiences between roms and battery life?
Yeah I agree that stock seems better than aosp based. Even using similar kernels (perseus on stock v devil on aosp)

yes.stock is better

Honestly, I've also used the SlimBean. Consumes a bit 'too much for my taste, the only ROM that does not have a battery drain is the Cyanogen 9

[Q] Fastest / longest battery ROM ASOP

Which rom do you use?
I find 4.4 to be very slow

Battery life in different roms

Any suggestions how to keep battery life longer with roms higher then 4.1.2? Every time i flash rom like cm kitkat, paranoid 3+ or higher my battery life sucks (battery life to 5 hours). And with 4.1.2 roms battery life is just awesome (about a day).
Sorry for bad english.

The reason why battery life is noticeably worse on kitkat is because of the lack of drivers available for or device. It isn't well optimised for our device and as a consequence, battery life is lost. If you absolutely want the best features (in kitkat) and want reasonable battery life, look for roms that have been built to be as close to aosp sources. That is look at rom like slimkat or neatrom aosp as they seem to have the least bloat ware and are running on the latest version of kitkat.

And how about kernels? Do they have any impact on battery life?

Kernels can provide driver updates to the graphics therefore there may be better performance in games. Most custom kernels allow the user to undervolt their cpu (and sometimes gpu) therefore accounting to battery savings. So yes, if tuned properly (sometimes if custom kernel settings are left to the defaults), there may be a slight improvement to battery life. As I said before, I can only recommend to you aosp roms such as neatrom or slim saber rom if you want minimal battery drain.

What Rom has the best possible battery life? 2019

Hey guys, I'm looking for a rom that has the best possible battery life. Doesn't matter if it's slow or lacks some major features, even KitKat is fine. So what would be the best possible rom with just battery life in mind according to you?
I'm probably gonna go for dotOS. Is the battery life any good? Or is resurrection remix Oreo better?
Stock rom, based on MIUI 9 China rom. Idle drain overnight hardly 2-3 % for 3 year old Mi Pad. Only downside it's based on Kitkat.
But doesn't matter to me, as I use it for playing PUBG and watching YouTube and normal browsing.

Original KitKat Miui indeed has the best battery life and I would use it as well but you can't double tap to fast forward in Youtube with android 4.4 which is something I need...
Go for Lineage OS 14.1 by Artemka. Battery backup is good. Using it currently. LOS 15.1 has bad battery backup.
