[Q] Best Kernel/ ROM combo for battery life

Hello All !
I have a Note 3 (SM-N900T) and my battery is fairly well not the best. After doing some battery analysis. My kernel keeps my phone awake among other apps which have been uninstalled.
My question is can anyone recommend a ROM that is fairly close to pure Android but still has S-Pen functionality . I want a ROM that is easily less than a Gb in size as its much easier on the system plus I also want a kernel which has the best battery performance and if their are professionals out their, can anyone recommend me some underclocking/ volting settings. I'm not a professional by any means but like others i'm fairly keen to learn. I would like a phone that easily gets me passed a day or even nearly 2 days of battery life. I'm not a heavy user of my phone, I switch off all toggles when not in use, i regularly greenify all apps, my screen brightness is always low and yet for some reason even a mundane task of watching a 5 minute video off youtube drains my battery by 3% or more.
Current ROM/ Kernel: Stock ROM (Android 4.3) + Stock Kernel

What kernel should use with this rom? I still use x_kernel v3

Can anyone recommend some good stock Android ROMs with S Pen support.
I heard some good reviews regarding Lean kernel. Can anyone validate this.

Which custom ROM to pick?

Would be lovely if we could get a brief introduction of the different custom ROM's out there for S6 Edge Plus.
I can update this post with what I/we learn.
Okay, I can begin with asking; which ROM has most features, customizations and 'neatyness'?
I'm currently running BoBCaTRoM.

As we have not much options in present days, you have a chance to try them all. In my opinion; Audax is the best.. Seems not has many features? You can do all as you wish. Thanks.

I'm currently using the CRISSCROSS ROM v1.6. It's extremely good and you can add and remove alot of stuffs on the ROM (under AROMA Installer) before you are installing the ROM. So there are alot of options to choose from.

best s8 rom port?

Hey guys. I don't mean to be rude because I know I can do the research myself. But I was wondering if any of you have tested the s8 ROM ports, there are a lot lately and I was wandering Wich one do you think is the more stable and has good battery? And thoughts?

Well I am on project dream, that is first s8 Rom i installed and it work awesome, same battery life as on s7 edge rooms, with my usage around 5-6h sot. I want to try project Alice but I don't have any good reason to replace this rom...

I also wanted to install now a S8 Rom port but I can not decide. It seems that none of the currently available is stable and that there are many bugs on all of them based on the comments....
I downloaded the project alice but I am not sure if I should flash it, because it is beta, or use a finished one?

khongloi v2 is the best, good battery life, and almost everything is working. he managed to fix things like the smart view private mode and all those things that aint working on other roms. and it is the first s8 port rom to be made. try it

I could tell you that's it's sac23 port but it's pointless... What I found in that rom maybe isn't what you're looking for... Try yourself is the best option

I use project alise. Disable fast charging first. I have today 3 hours sot and 55% left fast stable. Sac rom drain batery.

I'm using sac23 rom with superstock kernel 2.5.2v as my daily driver

Hello, thank you all for the information.
@efkka23 did you face any bugs on project alice, if yes, what kind of? Does BT works as it should? How is the procedure with installing updates of the rom?

you had to flash the modded kenel by the developer, then the rom boots up well

Whasapp, bbm, xda, Fbooklite, browsing with opera. And video test (on airplane mode). This device is great for playing video rather than browsing always looking for network. I've compared, without playing video (just social media and browsing), I reach 6hr 30 mins sot but battery stay 30%

i used s8 port by ambasadii and it worked very good, didn't find any bug in the 2-3 day i used it, i'm now testing others but keep ambasadii as the best for now, good battery life.

I am using Batman rom 1.3 ..
No bugs found,

Just went through the motions of going from superman rom to the batman rom. Really enjoying it at the moment so that's another +1 from me port. :good:
Without getting off topic, my bixby home (the far-most left screen on your homescreen) does stop working a few times on my flash, but i've disabled it and works fine, kind of annoying as i used to use it mainly for news feed screen on the s7 roms. Whats a good alternative? Used to by one of my main reasons for sticking with Touchwiz, with that not an option for me I've started experimenting with Nova Launcher.

Horrible battery life even with new battery

Hi !
To make it short , i even downgraded to kitkat , and got my self a new battery , it's a taiwanese battery, couldn't find authentic battery anywhere.
The best sot i could get is like 5-6h ( video playback). Normal usage would get me 2:30h or 3h top
Share your usage please . Im hating this phone

Please delete this. There are numerous threads here about battery life. We don't need more.
The phone is not from yesterday !

d no restart for 1week

My battery life significantly improved when I flashed Lollipop with full data wipe (totally clean fresh install).
There might be certain apps draining your battery.

I'm seeing several issues...
1, Facebook is running.
2. Whatever that Ludo King app is, it is using the majority of your battery.
3. unofficial, non-big brand batteries are always worse.
Try Greenify. https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
(If you're in the Netherlands, https://www.gsmpunt.nl/ still sells official batteries.)

Ludo King seems to be killing your battery big time.
Try Greenify app. It works amazingly well.
How can you say you cannot find the authentic battery ... ?
You can find the original battery from many ebay vendors
Also in amazon

Im at 64% with 1h sot
It would be nice if you share yours guys

I am on 51% with 4 and a Half hours SOT. I am running Resurrection Remix Nougat V5.8.3, i am using my brand new Note 3 Powerbear Battery from Amazon. I use greenify to hibernate applications running in the background including system apps. I also tweaked my LMK and kernel settings with Kernel Auditor.

Does it worth rooting to improve battery life?

Hi, I have Samsung SM-G935F Dual sim phone (bought used) and today I replaced it's battery thinking there was an issue with the batter as it was draining like 1% after 3 minutes with SOT but with the replaced battery I have the same effect. Searching through the internet I came to know that this phone has awesome battery backup but I wasn't able to witness it myself so far. The cell is pretty good with screen off but with screen on the battery drains fast. Under heavy usage it lasts for 6-7 hours max. Youtube, Whatsapp, Facebook.
So should I install a custom rom? I don't think so as many people have said this phone's battery time is impressive.
Any feedback would be appreciated. P.s. I'm' on latest Oreo 8.0.0 and I can't get to the battery usage screen either no any other application helps. Thanks in advance. I wasted 7$ on battery already.

S7 Edge has a good battery backup. If you are running stock ROM then your phone should be filled up with bloatware as well. You can give a try by rooting and installing a custom ROM. Even after custom ROM, if your battery drains as before then it could be an hardware issue.

Use odin and flsah TWRP recovery. You will get lots of post when you search in xda forum itself.
Note: First backup your data before doing anything.
