Hi. I just wonder about this.
Many times, when a new firmware comes out, after 2-3 days there are custom roms based on it, with tweaks (edited build.prop for example) and other speed mods.
Do they really improve speed? I mean seriously, if someone tests the 3-4 most known stable custom roms, based on same android version, and with the same kernel, also with the same apps on it, will be any noticeable difference in speed?
I see other devs releasing a rom after 3 days, and I can't explain what kind of tweaks could give more speed being stable at the same time.
Maybe custom roms are just modded/themed stock roms, and when there's a speed differenve it's because of the kernel inside.
Just being curious about that (also could make the choice of the rom itself easier...)
Any opinion? From your experience at least.

A mixture of both .

definately a mixture of both. They both make huge improvments over stock. in my opinion anyway
probaby karnel or speed
some costum rome improve your phone speed or karnel speed. especially visuality.

I don't need to improve my phone's karnel speed, it gets enough girls as it is.
However in my experience speed improvement and the smoothness that comes with it are mainly the process of the kernel as that controls the interaction between android and the hardware, where most performance bottlenecks happen. The ROM itself adds functionality, appearence and most important of all...stability.
At least so it appears to me.

I partially agree. I mean, if we assume stock roms are stable, custom roms can;t be more stable.
So, they provide some speed, maybe because there are not so many system apps inside, and mostly they provide some nice mods (visual and functional).
Could anyone outline the merits of Kitkat roms when compared to jelly beans? How is multitasking with Kitkat?

Kitkat is supposed to be 17% faster than jelly bean.

Kitkat roms are mostly based on cm and aosp, so they, apart from being faster due to improvements and support for art runtime, also have a slew of features such as pattern lockscreen upto 6 x 6, album art on lockscreen, and many more..

there are many merits like others said but negative side effect is the poor battery backup no matter what rom you use , what settings or whats your usage pattern, you will surely experience faster battery drain
apart from only this everything is superior, faster and functional than earlier versions

You have to give away the juice for performance. That's okay. But what about multitasking on KK? Is it fast? Is it lagfree?

I don't experience any faster battery drain than on 4.1.2 official TW rom and on newer custom JB roms. Only on TW based HarshJelly i've got slightly better battery life.

yes its lagfree to some extent since the hardware still remains the same

Well I've actually always experienced a very good battery backup with KK comparing to the old 4.1.2 stock I had, which was also very laggy.. Of course with some roms (I'm seeing it on PAC man) you will get lower battery life according to the optimization/weight of the system itself.

its a known and accepted fact that kitkat conumes more battery then jb roms atleast on our device no point of arguement, but yes there maybe slight variation from rom to rom as i am using beanstalk its ginving me better battery backup then other kk roms which i have earlier used
Last android version of android not mean the best.I always was changing roms.But why?Just pickup a rom which meet your needs.Even its a AOSP,you can customize it with xposed.For me, MIUI meets my needs,of course i want cpu and gpu oc on kernel for MIUI...About battery,every phone will get different results with every rom.Why? Because :
-like any battery,it become fat and this problem cant be solved by just changing rom / calibrating battery
-everyone use phone different = different tasks = different results
This is my opinion.

I must say that my old 4.1.2 (ITV), the one before the december update, was very laggy/buggy and had a higher battery usage. That's a particular case of course, but it happened

Stock UBLPK firmware has much improved in battery performance.

My own experienced with Carbon 4.4.3 :
Everything is smooth, performance is better than stock 4.1.2 . battery drain fast, but i always have spare battery with desktop charger so for me it's no issue..
Also i OC my GPU lil bit with novathor tweak (built in from roms) . so gaming performance significantly increase too..
For multitasking, i prefer tweaking OOM by myself to suit my needs..
Personally i'm happy with this config...
Carbon kitkat 4.4.4 by Flo008 gives awesome battery life and performance.

@Nishad1982 Yeah good for a bit of multitasking. But I don't understand why people worrying about multitasking in a mobile device. What they want? opening 15+ apps in the same time? I never had a need to open more than 4 or 5 apps at a time. But you really want to do heavy multitasking, then you can tweak the minfree memory values to suit your need. (lowering the minfree settings for all categories by one or two simple steps)
But always remember, we only have a device with 620+ user available ram. Good luck for your Carbon Rom experience. (BTW, a new build is released today)

A bit of multitasking that all I need. I do not want my Dialer lag when I need to make an urgent call while doing other things like browsing.
And 620 MB is a huge RAM for a phone.
I'm looking for a kernel and custom rom that give me a perfect balance between battery life and performance on my Nexus 6. Thanks for the help.
Bliss pop and elementalx
I use BrokenOS(personal preference, mainly for UI) and Sensei kernel for battery. Its extremely customizable and upstreams the best features and optimizations from other kernels like elementalx and Franco and the likes. He releases it a few days after (or day of) and its extremely customizable. I've used it since release 5. He's currently on release 34
BlissPop and Franco Kernel :good:
I notice significant battery improvement with ElementalX kernel over stock kernel.
first off, kernels do not give you better battery. its a huge misconception. a kernel can help you better your battery, but will not improve your battery. you can get the same improvements by messing with your cpu yourself. battery life is all about how you personally use your device, how you set it up, what kinds of apps you install, and ver much the quality if your phone/data signal. thats it. there is no magic pill(kernel) that you can take to improve your battery life. if you want better battery life, keep away from terribly written apps, and apps that drain your phones resources.

Even then some kernels have customizations and optimizations to help lengthen the battery life. For example different CPU govorners and reduce unneeded clock speed overhead and under clocking can help too with the help of a custom kernel. So yes, poorly written apps and sensors that hog power tend to be the majority of power loss, I still think that the kernels introduce a bit of help too
Hello, what is for you the best kernel/governor to get smooth and responsive experience with the best battery life ? Thanks.
Im on jdc team aosp rom and the battery life plus performance is excellent on the stock kernel settings. You can try bb kernel for this rom too, which has performance benefits and maybe minor degrade in battery life, not noticeable to most users. Ill suggest you use stock kernel on this rom. Note: im also using google play services doze and unified hosts adblock magisk modules. For good battery life, download the app called app opd from play store and from there restrict background activity permission for apps you dint want running in the background and dont want notifications from. Also restrict keep awake permissions.
Ive tried tweaking kernel settings in maby ways in many roms and many kernels. It never gives any better battery life, rather affects performance badly. Dude you bought a snapdragon 820 phone. Dont worry so much about battery and enjoy your life. Use my suggestions in first paragraph and youll be fine.

Seriously is there's any Custom ROM that doesn't lag while gaming, gangbang my battery with useless processes, doesn't hang up calls by itself.
Briefly I'm looking for a rom that I can use as my daily driver higher than Marshmallow.
I thing You don't find any rom higher than marshmallow. Some stable builds have also some bugs.
I got tired with this device...
Gonna buy xiaomi mi a1. No need to flash any custom roms cuz of pure android.
I recommend you Omni Marshmallow. Fast, stable and battery life is very good.
Well, most of them are stable, but they suffer from a lot of bugs and issues. The only ones that work flawless are those Stock modified ones from Persona.

I'm just bored of this IOS rip-off interface (EMUI) so if I'm gonna install a custom rom i prefer it not to be a Modified EMUI one, and sadly custom kernels that we have now only support EMUI.
Marshmallow stable roms: Omnirom 6.0, Cm13, Lineageos 13, And pac-rom works fine to me.
Nougat stable roms: DotOS,Omnirom 7.1, LOS14.
Oreo stable roms: Nothing ( there's only 1 but have so many bugs)
This is my personal opinion only and you can try them but follow the instructions and if havent signal and wifi try installing fisrt another stock rom L21,l23 etc.

I'll let you know after I fully test the ROM but so far battery life was not so bad.
RR if u want Nougat
Persona78's rom if you want Marshmallow
Firmware B203, it has Android Lollipop but it has a good battery life @DarkJoker360 can confirm it
No way guys, if omx bug will exist no custom roms are stable

RROS 7.1 ROM TEST 1-1-2018
**Provided test is compared with device hardware specifications and stock ROM along with how the custom ROM should function**
_
Battery life: 6/10
Battery was disappointingly way worse than EMUI battery consumption testing using system panel 2 gave results that there was a large power percentage that is consumed by "unaccounted" which means that ROM is incapable of managing power consumption in a proper way, other major consumers were "Google Services" and "kernel"
Regardless of who's developing this rom Resurrection remix is known to bring performance higher than stock and with the lowest battery consumption possible however in this "Unofficially developed" ROM battery was a real TURN OFF.

Performance: 8/10 is forgivable
Performance didn't really change smoothness was all around and playing asphalt8 on medium graphics was lag free, video playback was not bad tested original gallery player and performance on MX player also Xplayer there was no noticable frame drops the only problem here is that the device overheats really quick either if you're gaming or playing videos.

There was no sudden crashes related to bad coding while using this rom stability was just as good as EMUI.

For you it s stable? I have the maximum respect for all dev here but the rom for me is not stable, there is omx bug, no video recording with stock camera, video playback with lags, video recording with footej in 1080p laggy, YouTube 720p60 laggy and camera bugged on WhatsApp video calls.
It s a personal opinion. Maximum respect for all users and devs.

By stability I mean sudden crashes and compatibility with older apps, video recording and playback is categorized with performance, I haven't had any issues with YouTube or whatsapp video playback works very well and hardware composer works smoothly, I am sorry I didn't mention recording in performance test but it is considered.
I'm sure @surdu_petru can fix this in future updates.
By the way can you please provide link to the mentioned lollipop ROM with good battery life please?
