[Q] Best ROM battery wise (either stock or AOSP based)

So I just rooted a friend's MyTouch 4G Slide and now trying to figure out which ROM to use. I have her trying JellyKang 1.8 which so far has been a horrible nightmare in terms of battery life on her device. So is there any advice on either a better ROM that doesn't have a battery drain issue or a kernel that might work better with JellyKang?
Also how hard is it to s-off this device? The laptop I would be using is running Windows 7 x64 if that helps any. I noticed mentions of the wire trick but beyond that what do I need in order to get this done? This would make swapping kernels much easier.
Thanks so much in advance for any information.

A "best ROM" thread always gets a lot of controversy. Everyone has different needs and opinions on what is/isn't important to them. If best battery life and everything working without glitches is paramount (my criteria), then a stock-based ROM like Miktouch 0.7 will work best for you. There are some newer ROMs that offer good performance with minimal glitches, though, so read through the comments on them in the Dev forum and make your informed decision.

Yeah I certainly understand what you mean by controversy. I'll try Miktouch since to be honest my friend isn't quite liking the AOSP/CM experience so far. Thanks!

How to select a kernel?

Hey guys,
So, I was wondering.. I am new to the all android experience, I am learning and I am enjoying tweaking and messing around with my phone.
Problem is that I am really un knowledgeable when it comes to kernels and roms..
I tested at least 5 kernels today and tbh apart from system performance on antutu i'm not seeing much, i'm wondering how people can reach 19 hours on here when no matter which rom or kernel I pick my phone just keeps draining pretty fast when i'm playing games..
I want to learn, to understand more.. but for that, I need help.
I want to know how to select a good rom, a good kernel, what features to look at, how to mess with voltages and etc..
I would love to learn, so someday I can be the one assisting other android users.

Only one way to do that : READ READ READ READ and read some more. And don`t be afraid to try things like flashing roms, kernels, recovery`s, mods. Always read the OP`s of the devs well so you`ll know what to do,

Thing is that most people here are already.. " in the zone " when it comes to knowledge, so they speak the language that I don't understand.. it's like chinese when I first look at it.
How does a beginner evolve like that?
Btw: I was wondering maybe I should test kernels and roms for a period of time instead of periods of hours? because I don't see immediate results I just switch a rom or a kernel not really giving it a chance to evolve

All users start from scratch bro, we all live and learn till the day we die

First don't care about bemchmarks. They mean nothing in term of user experience.
Second a kernel must be tried at least during one or two days.
Third there is no best Rom our best kernel. Golden rule. Each person has different needs and tastes.
And be careful when you see amazing battery times. What matters is phone usage. Good phone network ? Wi-Fi? Localisation always on? And so on.
What surprises you when you play your battery drains? Normal.
What makes difference is 'idle' time. Use Greenify, fight backend running apps.
Some people spend days tweaking their phones, and though don't have time to use it...

this is normal... what do you expect when you stress the CPU/GPU?

Thing is, you don't just change kernels and run. Many of the efficiencies you gain with custom kernels comes from the tweaks you make to the system made possible by the kernel. These are where you can get increased performance in many respects. Keep in mind, though, no matter what you do, the processors will still be hungry under load and there is not much to do about screen use except brightness control. (i.e. games will kill your battery faster than just about anything else)

Looking for a specific rom

Well I'm not entirely sure what I'm looking for as this is the first time i'll ever install a custom rom.
I'm mainly looking for Battery and Performance, don't really care for features, but they wouldn't hurt if skins were great.
I've chosen a kernel already, which will be Franco Kernel!
Due to it's features of battery saving.
Also another question I have is for things such as Nightly and Stable releases etc, do I need to do a clean wipe every time I wish to update versions of the rom?

well, generally, you arent allowed to post threads on xda asking about which rom(battery being the most requested). what is told to you is try out a few, decide which you like best, as we all have different needs and wants, and our devices all react differently. anyways, battery is not about rom or kernel(yes, you said you like franco for battery). battery life is nearly all about how you personally use your device, how you personally set it up, what apps you use, and very much the quality of your phone/data signal. everything else plays very little into it.
with every kernel someone will tell you that it gives the best battery life, someone will say it gives terrible battery life. there is no magic pill, it does not exist. i know you read about kernel so and so and its amazing battery life, but it is usually just fanboys spreading the use of the kernel.
anyways, if you are updating a rom, feel free to dirty flash it. no need to wipe.

CM11 vs Stock? Anything better?

I've been using the nexus for a while, and although I like the stock rom, is CM11 better? Or any other rom in fact? And I guess when I say better I generally mean performance and possibly battery life? Would a kernal also affect this?
Sorry if I seem naive or anything. Recently switched from an ATT S4 with all its bootloaders and such..

"Best" ROM.
There is no such thing as a best ROM. The question itself is ambiguous. "Best" is obviously a subjective term.
What I want from a ROM may well differ from what you want from a ROM, ergo - what is best for me could be worst for you.
If you are asking what the most popular ROMs are, or which ROMs people are using, you can see which threads stay around on the first few pages (and have the most posts) in the Android Development or Original Android Development forums. You can also see what other people are running by reading the What are you running on your Nexus 5 thread.
If you are asking which is the most stable, being a Nexus device - they're all pretty stable.
If you are asking which is best on Battery, ROMs only affect battery if they have a feature that is badly coded. You will likely be able to read about this in the ROM threads. ROMs do not impact battery life. The only impact to battery life are your apps, your settings, how you use the phone and mostly, environmental issues such as Phone Signal.
For tips about improving battery life, please read [Battery Life Help] Troubleshoot battery issues here!
"Best" Kernel
Also, please note that as above, "best" is still subjective. What we all want from a kernel is different. Again, many people have the misconception that Kernels affect battery life. Let's get this cleared up. Although Kernel devs will build in optimisations and efficiencies that will improve battery life, these are very, VERY tiny...and if 1 kernel has these optimisations, they likely all have.
People will often say "Kernel x is better than kernel y for battery life". This is actually wrong. Kernels respond to user settings. Setting up the governor to favour either battery life or performance is simple enough to do, you just have to do some learning. The reason people think Kernel x is better than y is because developers set their kernels up with their preferred governor settings. This is what we refer to as out-of-the-box settings. The out-of-the-box settings for kernel x may well produce better battery results than the out-of-the-box settings for kernel y, which favour performance. The fact is, you as the user have the ability to tune kernel x or y to perform the same, be that battery or performance - so start learning how to do this yourselves - that way, you can choose the kernel based on the FEATURES you want, and not the fictional performance benefits of one kernel over another.
Hope this helps

The biggest thing is some of the customizations you can get with something like Xposed. A kernel might change things. You can always make a backup.

You should add the following to the end:
[THREAD CLOSED]

CM and other ROMs that have SuperSU baked into the system (as opposed to have it installed as an app that shows up in the app drawer) can have difficulties with apps that won't work due to being rooted, and often times the apps you can use to temporarily block/hide root access won't work properly with SuperSU baked in. That's the big reason why I stopped using them. It's simpler to just root stock Android and use xposed modules that can replicate 95% of what CM brings to the table.

[Q] Custom ROM vs Stock ROM (thoughts/suggestions/etc)

One of the reasons I purchased the Nexus 5 is because it is Android at is purest. After I got the phone, I used it for a while without rooting it, until I needed to use an app that required root. So about a month after having the phone, I rooted it. Now I am finding some things that KitKat doesn't let you customize. They are all minor interface things but I'm sure everyone here can relate... I want more customization. So, here are my questions:
How long before you rooted and/or flashed a custom ROM?
Are you happy with the stability of your custom ROM?
Any difference in battery life?
Which custom ROM are you using and why?

1. Day one I rooted.
2. Most roms on a nexus are stable... Except maybe some nighties, which are works in progress.
3. Roms have very little impact on battery life.... So don't use that as a deciding point.
4. Mostly you'll just get a list of the most popular roms when you ask that. But I'll say Graviton. Cause it's a little different than some... And the Dev is very active in his rom thread. Always a good thing.
5. questions go in Q&A. For future reference. ?

Please post questions in the Q&A section
Thread moved

I have rooted the device, the first day I got it, uninstalled bloatware and other crap, installed *my* favorite Apple and I am happy. I did Not finden *any* thing, which could not be customized. What specific point are you missing in customization? My device runs fine, I use Greenify app, so the battery runs about 48 to 60 hours depending on the programs I use. Video is more battery consuming that making a call of course.

There's another alternative in case you have a dilemma whether to stay on or leave stock ROM. Check out my GravityBox project (xposed module).

Wow, I just started using Xposed on my tablet but didn't realize it was capable of all of this. Definitely going to try this out before flashing a new ROM.
P.S. Sorry, not sure what I was thinking... for some reason, I thought I was posting in Q&A.

I left it for 3 months. Then used xposed and gravity box to get the notification toggles the way they should be.
I shouldn't have to have it take me into settings to toggle data on and off.
Other than that stock is pretty well perfect for me.

Stock Nexus is Android at its purest... with Google apps and services added.

After the OTA images of Lollipop came out, I knew since I was rooted, I would have to do a manual install. So I'm back to stock (non-rooted). Right now, I don't see a reason to root. So far Lollipop 5.0 is serving it's purpose. Yet another huge step in the right direction by Google.

Flashed 5.0 factory images the day they came out, was not satisfied with the OS as a whole, so now flashed a custom ROM Mahdi till 5.x.x comes out or any AOSP 5.0 rom comes out.

AOSP 5.0 roms are already out.

I ordered mine Oct 31 last year. Unlocked the bootloader day one. Probably stayed stock for a bit, don't know how many custom ROMs were out at the start.
Stayed on Cataclysm for a long time, went to Purity. Flashed stock 5.0, was on that a few days and now a custom ROM again.

I know about that, no offense to the current rom builders but I was more like waiting for slimpop or cm12 or paranoid android roms. But I have a question most of the roms come with gapps built in them which i find confusing as no rom built from source should do that, or are they just themed or mod-ed stock roms?(which is the primary reason i haven't yet tried them out)
