[Q] New to custom kernels? Help

Hello, I'm new to kernels and know not much about them except you can flash them like roms but, exactly where can I find a place with the most reliable kernels and if so, which one would be the best in terms of giving me the greatest/fastest performance? & also another different kernel that offers great performance as well as great battery life? (Running CM 10.1 stable on GS3, T-999)

Actually no one can give you an apt answer rather than yourself for which is the best. You may have to try yourself to know which is the best kernel, just like your try ROMs. Go to your device forum, pick up the most active kernel threads, read comments and feedbacks from members in the thread and you can try after getting an initial idea about the same.

Trying to understand ROM and Kernel

Hello, i didn't find any answer so here's my question :
ROM :
What's the differences between 2 customs ROM ?
I mean, i have seen like 10 different ROM based on the same android version but i don't see any difference.
Why shouldn't I stay on Cyanogen ? I don't get it.
Kernel :
I think i kind of understand the benefit on a custom kernel (overclock, maybe better battery life ?) but isn't it too risky ?
How does kernel compatibility work ? Is it based on an Android version ? Do 5.0.0 kernel will be compatible with a 5.1.1 version ?
Do you really feel the difference compared to the stock cyanogen one ?
And my last question will be : does cyanogen 12 (and 12.1) have OTA update or do i have to flash new zip every day ?
Thanks !!

The ROMs might look the same but they're not. Features are implemented in different ways, plus there's a lot of unique code that you don't see which can affect many things, like speed and battery life. Also, you'll find that different ROMs have different feature sets. All in all it's up to you to decide which one is best for you, so have a look through them and pick one to test out. If you don't like it you can always flash another.
Custom kernels can offer extra features like overclocking, undervolting, fast charge while connected to a usb power source. There are risks involved, like if you overclock it can reduce the long term life of your CPU, undervolting too much will lead to instability.
CM12 (and 12.1) are nightlies which means there's a new build every day to update to (if you choose). You can either flash them manually or download via the OTA system. Not all ROMs have the OTA system.

Thank you very much !!
Maybe i should dig more into the ROM's topic because their customs features are not listed anywhere.. That's too bad ^^
Do you know if all the gestures are implemented on CM 12 / 12.1 (not only double tap but all of them) ?

Yes, as far as I know the gestures are implemented, they have been on all ROMs that I've tried anyway.

How come custom kernel like Franco's one can improve your battery life ? I've seen everyone talking about it ..

There are various differences between stock CM kernel and custom kernels, far too many for me to go into. Honestly though, the difference in battery life really isn't all that much. I never use a custom kernel and I still get great battery life.

Advice for new Rom (XT1039 Peregrine)

Hi,
I know that this is going to be a very subjective question, but can anyone suggest a super slick Rom for my Motorola 4G LTE?
I tried CyanogenMod but did not fair to well with it - some lag and increased battery usage.
I really need something super lightweight and prefer function over nice looks.
It seems that three of the best contenders for this phone are Carbon, Paranoid Android and SlimKat - can anyone perhaps point me the direction of which one to use (or indeed suggest anything even better)?
Thanks very much.

CM 12.1 is very slim, if you just use the smallest package for gapps.
greetings

Thank you both for that - I might have to try both suggestions and see which works best for me. (I am currently using CM 13, which might be the reason I am having problems).
It is very interesting that abhi0502 has mentioned flashing the Kernel - this is something I was not even aware of until now.
How does flashing a Kernel and flashing the ROM tie in with each other? I always thought that a new ROM would automatically provide its own version of the kernel.

yes it has own kernel but if battery and performance is not good as expected you can flash kernel (that is the reason i have rooted the phone.) You can flash kernel with cm13 currently and see if performance improves. But its always recommend for clean flash (Rom+kernel+gapps) to avoid errors

Just wanted to pop back on here and say thanks for the advice above.
I did try flashing the kernel as suggested but it kept causing my phone to randomly reboot - although it did not work well for me on this particular occasion, I shall definitely start experimenting with other kernel's in the future.
As suggested I wiped and reinstalled Resurrection Remix with the smallest version of gapps and not only is my phone massively more responsive, but the battery improvements are really noticeable.
Thanks again.

Stock ROMs faster than Custom ROMs?

Hello everyone, greetings!
My question is are stock ROMs faster in loading and launching apps than custom ROMs
I'm asking this because I'm currently on RR 5.8.2 and I'm starting to feel that Stock 6.0.1 feels faster(sometimes).
What are your thoughts on this?
Yours Respectfully,

Hello,
You could give a try to LineageOS 14.1 ROM.
I find it better than the Stock 6.0.1.

In many cases, yes... the stock ROM is faster, more efficient, and more battery friendly. Moto might do a lot of things wrong, but they know how to optimize a ROM and kernel.

Yes, is better.

Is lineage os something better?

Stock ROM 6.0.1 is only faster if you are using another customer Marshmellow ROM. However Custom Nougat ROMs are alot faster than stock Marshmellow ROM. This is for simple reason that Nougat is better than Marshmellow. I have tried most of them and also I went back to stock for few weeks and I was feeling Stock ROM is working in slow motion as compare to Nougat ROMs . However battery consumtion and optimisation is far better on stock ROM as compare to any other custom ROM.

Lineage is simply nougat and stock is simply MM. speed-wise I would have to run a lot of tests to find out which is faster. I run Lineage because it works (for me) and it gets the security updates, which MM does not. Have no idea about RR.

I think people play a lot more with their new toy (custom rom) so the display is on a lot more and this will kill any battery. It's not the rom, but the user.

Given the same type of use I find that Lineage is ever so slightly better on battery than stock 6.0, but I would expect that as N is supposed to be ever so slightly better than M.
Example - daily use, I used to run stock 6.0 M down to 85 regularly and N is generally 90 or 88%. XT1540/US/ATT/GoPhone. There are days where I only run LinOS down to 97%.

Yes it does alot fatser on custom ROMS. I have tried most of the ROMS in this forum . Battery is best in Stock Marshmellow ROM. The only ROM which is closest to stock is nearly pure Nougat ROM https://forum.xda-developers.com/2015-moto-g/development/osprey-aosp-caf-7-1-1-t3576936
Try this one has best battery life . also make sure you read Q&A on bottom of the page for further battery saving of above ROM Thread
Lineage OS is also a good for Battery as compare to most of other Nougat Roms https://forum.xda-developers.com/2015-moto-g/orig-development/rom-unofficial-cyanogenmod-14-t3466246

Do you guys calibrate battery after flashing new roms?

Hi All,
My experience has been a little different from others here. My phone usage is lesser compared to others in general. So I am writing based on that:
On Stock MM 6.0.1 on Osprey I used to get 4-5 days on a single 100% charge.
On Custom Nougat 7.1.1 (GzRom Tesla) with similar usage pattern as above I consistently get 8-10 days with a single 100% charge.
Also custom roms feel way faster than stock roms.

A thing of the past... "Calibration" today is nothing special, just let the battery drain until it shuts down on its own and then fully charge. That's all they mean.

Not really... I've rarely seen it make any real difference unless you have an issue where it doesn't seem to be charging fully or it's shutting down at more than 3%

Suggest the best Nougat Rom for my moto droid turbo(Indian Variant)?

I want to install a rom, Nougat based which has very minimal bugs. Should be best in performance and battery backup. I am very new to this Moto community. So confused to select. Suggest me some best rom.

My personal opinion based on what I see people write in the threads. If you want Nougat, any of these three ROMS have very high reviews. You can go to those threads and ask questions.
[ROM][All Quark][7.x] Resurrection Remix
[ROM][UNOFFICIAL]AOKP 7.x For All Quark
[ROM][Quarks][LOS/CM 14.1 Unofficial][7.1.x][2016-12-30] (hybrid of CM14 and Resurrection Remix)

[ROMs][Quarks][List for Moto Maxx, Moto Turbo and Droid Turbo]
https://forum.xda-developers.com/showpost.php?p=73917795&postcount=91
I only bothered with Nougat and Marshmallow, didn't list any Lollipop ROMs as those are very outdated.
I'm still using RR 6.X (Marshmallow) by the way on mine and my wife's XT1225.
________________
EDIT:
I am now running of those top three -- RR 7.x instead of RR 6.X, which I was running at the time of this answer back in April. Back then I wasn't ready to move to Nougat from very stable RR 6.x, but now have.
But still these are probably the top three. It's my opinion, based on comments, questions, developer response in the threads.

Thankyou very much for spending ur time in replying me. which one do you suggest? Actually, in some roms (mobiles other than moto) i experienced call drop issues. its like If someone are calling ,Im unable to see any call screen or any vibration/ring sound. But they can hear that they are calling me.So, By installing one of the above roms, Would I face this issue? Please suggest me a best of the three. Thankyou

None of those three ROMs would have that issue. All three of those devs have been active for quite a while with these Quarks. We welcome all devs -- but I will trust those who have proven over and over and over to be responsive to users questions and will help solve issues.
I was on CM12.1 (Lollipop) until last October 2016, and it was rock stable. So, I was loathe to change, but I went with RR 6.x (Marshmallow) -- yes about the time Nougat ROMs were being made. I'm still on RR 6.X, but I'm active in all the Nougat ROM threads. I see the complaints, I answer questions, and I know what are ROM issues and what are really user issues.
But when I do switch to Nougat, I am leaning slightly towards RR 7.X, just because I've had a very good experience with RR 6.X on my phone and my wife's phone. And of the three LG phones I support (for friends), I installed RR 6.X on two of those, so I'm more familiar with Resurrection Remix layout.

Hi. Please help me. I have followed each and evey step and installed RR 7.1, the latest april build. Phone booted normally. But the problem is I cant proceed with the setup after language selection as when I click on "start as a fresh" or "restore from backup" options, I am getting a message "setup wizard keeps stopping". I went to recovery and made a factory reset but no change at all. Please could u help me what to do?

You should ask the question in the RR 7.X ROM thread, where users of that ROM can help you. I'm not using Nougat ROM myself.

I have flashed the RR Nougat, coming from a MM stock. Could it be realistic I experience some loss of performance at high demand tasks (like games?) and quicker drain of battery?

Normally there's a trade-off of performance vs battery, depending on which kernel governor you choose. But you are experiencing both?
For instance "conservative" governor gives better battery life, "performance" governor of course gives more performance but will drain battery quicker. Then there's a whole bunch of others (especially in @bhb27 custom kernel, which you have to install separately from any ROM) that promises to give better battery AND performance. Or at least a good compromise.
I'm currently using "alucard" both as governor and hotplug.
https://androidmodguide.blogspot.com/p/blog-page.html
A favourite choice and one of the original governors that Alucard_24 made. Alucard is based on ondemand but has been heavily tweaked to bring better battery life and performance. It has been known to be battery friendly without sacrificing much performance.

I can remember playing aorund with CPU governors on my Xperia Pro and DROID 4, but with the current custom kernel I am using bhb27I can't find the option to switch between governors, or set certain profiles at all. I could have been missing it.
Though, in short: does MM have longer battery durance and better performance? Cause I can't find any conclusion on this, perhaps a well respected expert like you might be able to tell me?
Also thank you for the info so far, I am surprised the attention you give to devs and members to help those in need! :good::good:

You are welcome.
To change CPU governors, hotplugs, I/O schedulers and such, you need Kernel Aduitor app found over in the @bhb27 kernel thread.
He provides a modded version of the app that works well both his custom kernel and the ROM "stock" kernel. His custom kernel has even more options.

I already found some modifications, set the governor to 'conservative' and it gave my Droid an instant boost and somehow a longer lasting on battery as when it was slower. I have no idea why, probably locks or such occured? Anyway it works flowless now and I will take your app also in consideration.
