EAS vs AKT

I see these terms a lot when kernels are being discussed to save battery life, can these two be used together? What are the differences? Thanks in advance for any information.

You really can't compare these to but.
AKT basically is changing kernel tunables in such matter that it saves battery or increases peformance depending on which the profile is ment for.. The problem is that everyone has a different usage pattern and everyone's definition of smooth and battery is different... For some Project Zhana can be really efficient and smooth while for me it is efficient/battery friendly but not as smooth.
EAS basically replaces the whole HMP part which almost every device runs now (HMP). EAS is quite new and quite experimental but really stable, you really won't notice it is experimental. EAS is a bit hard to explain for me. But if you are looking for a good user experience and the best battery life with it I would suggest you trying VertexOS.
Now correct me if I'm wrong I'm not a ****ing genius at this!

Awesome! Thank you very much for the info, I understand it much better now

In my experience, I get better battery life a balanced profile on AKT (fusion balanced) on OOS. But performance is amazing on Vertex! And battery life isn't terrible, although not as good as on OOS, and it is still very usable.

Thanks for the insight! I currently have the official Resurrection Remix ROM for my 3T with the latest EX kernel. Battery has been inconsistent for me even with the Wakelocks blocked and a mainly black theme, but I think it has to do with the weaker signal as opposed to OOS. I assume there is a way to apply these AKT profiles in the EX kernel app and have them apply after every reboot? I would prefer to stay with Ressurection over Vertex because it already has almost every feature available, and it would be much more convenient than flashing a different ROM each time for a new feature I wanted lol (since there is no Xposed for nougat)

Isn't terrible? It's much better....Better battery than oos or any other nonEAS rom...try it your self...give the battery three charging cycles and enjoy.....

See the link posted by @juliusedward.
ELI5: Basically, EAS and HMP are way to manage tasks in a multi-core processor. HMP requires a lot a guess work and experience to get it right. EAS is, Well, smart! It gets cpu utilization and load information using WALT/PELT (it's a new topic entirely. Think of them like a function, which they honestly are.) and decides which core is perfectly suited for the current given task and at what frequency. So, it is in it's nature to be more efficient and more battery friendly. Although, through lots of tweaking and optimization in HMP kernels it's not that bad either.

I run VertexOS.
EAS seems offer better battery life, same smoothness, and less warm !

Try Blu spark kernel. It's my favorite kernel in terms of performance and battery life. I can get 6-7hrs screen on time consistently over 24 hours on LTE and wifi. Performance is butter smooth. And when I mean butter smooth, I mean no frame drops, no microstutters, pure 60fps smoothness. Something not a single AKT profile can provide without destroying the battery life so I wouldn't recommend them, and yes I've tried every single profile. FlashKernel is also a really nice kernel but you need to tweak the stock governor settings to get nice performance.
Haven't tried EAS, but supposedly it does its job well, very well so you can also try that out. Try vertex it has been getting high praises.

@slamdunksaliby
Please check this post here
I think it is safe to presume that it answers your question to a great considerable extent.
Hope it helps.

P.S. AKT profiles cannot be applied on EAS, not yet.

Hi I tried Blu spark for a little on sultanized resurrection remix ROM, and the battery life doesn't seem to be very good, specifically with standby as sultan's kernel seems to handle it better, are you using the stock settings or are you underclocking? What ROM are you using with the kernel? Thanks!

Well u never going to have good battery life with RR. Try another rom and u going to see better battery stats.

Dont blame the kernel if you have standby drain.
I also use bluspark with freedomos ce and i nearly have zero battery drain over night.
If you have too much standby drain its some third party apps, services or something that keeps your phone awake.

You won't see much difference between kernels regarding idle drain. It's 99% apps related.

Thats what i was trying to say

Anyone interested in an Over clocked kernel or rom?

I've compiled Resurrection Remix with over clocked CPU (@2.2ghz) and GPU (@800mhz) and it's not that much of an improvement. I'd say PUBG runs little better now and some improvement in benchmarks. Well, I wasn't expecting miracles either but let me know if anyone wants an over clocked ROM or kernel. I am trying to add exfat support (I'd be happy if any devs can help me with that) as many user wants but I'm getting nowhere for now.

I can even take it to next level with CPU @2.4ghz and GPU @850mhz but I think that would be overkill.

I'm interested
How is the battery life?

I think it's little less than the stock ROM but now it depletes faster while gaming (as gaming pushes all cores to max).

Nice. That kernel would be great to VR

Well , good idea is to make only OC kernel and then setup it via kerenel audiutor eg. -- OC @ gpu would be nice because it is weakest part of MZP . I've just made benchmark on stock oreo antutu 7.1.3 = 75716 pts. while on latest Cosmos 3.2 rom result was 81703 pts.

i would be interested in a undervolting one

Yeah, that would be interested. I was playing wirh that, I think it was, Atrix time... Don't expect miracles but could add a bit to battery life. And a bit more in freezing the phone or crashing the apps

Under volting is not a good idea, it creates a lot of issues. To increase battery life use smart pixels, build prop tweaks and also amplify and greenify. However for screen on time, lowering resolution and smart pixels are best options.

Yeah, nice idea
I think stock runs on 8.0 while Cosmos on 8.1 so that might've improved it somewhat,
I wish if there was some tweak to OC GPU of normal ROM.

I think a kernel with overclocking possibilities would be nice. In fact, what I would really love was to see a port of Elemental X or Blu Spark kernels.

Kernel with best battery life for OP5T

Hey everyone.
I used to have New Kernel installed and it had the best battery life but sadly it stopped updating
I'm right now on blu_spark and battery life is not as good as i want it.
So does anyone know any kernel with a great battery life? Thanks a lot!

I'm using redflare kernel with lower cpus freq because i'm not playing games. With this kernel i dont have lag with lower cpus freq.

Hi, can you pass me that kernel for my op5t? I am using AEX 5.7 singularitu. I suppose it will be compatible. My rom does not use AES

Which Stock Rom and Which Kernel ?

Hi,
I'm stuck between Clean and Fulmics roms. Which do you think provides performance and battery consumption. My main question is; There are 3 kernels (Xceed, Solid, Gabriel). Which kernel should I use? I don't use anything other than web and whatsapp. I never play the game. Battery consumption and performance are very important to me. Thanks.

Xceed when I still use my G3 as daily driver is best for battery, and Clean comes with it. Fulmics + Xceed have some weird problem, so I suggest you go with Clean.

Thanks for the answer. Xceed kernel uses 3 core active. In other kernels, I don't know. Will the battery life be extended if I drop it to 2 cores?

Yes but it will cause lag for sure. You don't need to mess with Xceed, just let it do the job. Maybe doing some undervolt/current with Synapse.

Xceed 7n uses 3 cores, 5e kernel uses 2 cores. 5e I think I will see my work and do some testing. What are you using?

Annex: I also tried the gabriel kernel today. The GPU can run at least 27 mhz. The CPU can drop to 1 core. I think this kernel is very good. I will test this for a while.
- I did test. Xceed kernel is definitely better. (I'm using Xceed 7a)

I'm not satisfied with the performance, I using Aosp 5.8 right now.

does custom kernel improve performance?

hi guys so basically i started lagging on mobile legends when the game hit the 10th minute mark. does installng a custom kernel improve the gaming performance and fix the lag ? if yes do you guys have any suggested custom kernel ?

which version of butterfly can I flash on stock rom ? because I just changed from lineage to stock rom so i dont want to flash rom again lol

get the latest EUOC version corresponding to your android version, if you are on android 10 then there is no version for it yet, but you can test other kernels if it is the case
