Question:Custom kernel tweaks to improve battery life - Moto G4 Play Questions & Answers

I am on the latest build of RR with squid's kernel. As its a custom kernel, I am aware that I can tweak the kernel with some apps like kernel toolkit, trickster mod, etc. Can anybody help me with some tweaks using such apps to increase the battery backup?, as it has significantly decreased compared to stock rom (like undervolting, etc).
Thanks in advance

I use greenify and EX Kernel (there are other kernel tools) and have gotten good results.

Stock Kernel with Undervolt

Guys I have a question.
I have stock rom but I'm using custom kernel expecially for UnderVolt.
I want UV not for battery life, that IMHO don't get incresed that much, but for heat reason.
Is it possible to have a stock kernel just with undervolting? Would be that hard to build such a kernel by myself?

No, you cannot undervolt with a stock kernel. If you know how to enable undervolting in a kernel then good job!

Why would you prefer stock kernel vs other custom one? You get better results witth custom
In the Harsh kernel thread he's provided stock kernel with UV several times you can do a search there or ask there, also Harsh kernel itself is modified stock kernel with tons of optimizations, UV etc

[Q] Stock Kernel vs Franco Kernel

Hi guys, after watching videos on franco kernel, I end up installing it to my N7. After using it for several days, I noticed nothing much changed since the last time I'm using stock kernel. Is there any way that I can install back my stock kernel? or perhaps someone can guide me to use franco kernel effectively. Since my battery life isn't affected much by franco kernel, so I decided to revert back to stock kernel. Hope to receive guide from pro's out there.
Franco kernel has later changes and commits than stock kernel does. Performance and battery life without a doubt should be higher. You can configure the kernel using his premium app called FKU on the app store, or use a third party kernel app. Best of luck.
Seeing a stupid comment on Google Play about an app you love and marking it as "spam". You've done it too.

dude for one custom rom?

Because that, there are so many custom rom that you choose. Which would you choose?
I'm on revivorOS because stock gives me more battery fuel. Overclocked cpu with elementalx kernel and viperarise audio mod.
PureNexus with elementalX kernel works best for me...
DU + ElementalX + Lightning Blade

You can find DU at devs-base.
As for ElementalX I disable all memory killers, disable the 4 big cores, and use the interactive governor tweaks as described here: https://forum.xda-developers.com/showthread.php?t=2769899

I use LineageOS with this Pixel mod which works great! https://forum.xda-developers.com/moto-g4-plus/themes/lineageos14-1-pixel-theme-moto-g4-plus-t3544590 The performance is smooth. Decent battery life. (Better than stock) and every other week I get an update!
I was also testing lineage OS but I saw that for a month that does not update and now I'm testing jx creampie odexed, by facor write what you use to give me ideas

Best kernel for LOS OnePlus 5?

Best kernel for LOS OnePlus 5?

It's not about the Kernel, it's how you set it up.
Try boeffla kernel, very great battery and performance

So far yes.
I'm pretty sure he is waiting for an official Lineage build to act as a base for his Lineage kernel.
With LOS from what I have experienced on my oneplus 5T it depends on the revision... I am running AICP based some on LOS and with firmware 5.1. The simpler kernels seemed to be better performers overall. Alot of old kernel stuff we used to do in low ram slow processor days doesnt make as much of a difference that I could see. Overclocking , meh underclocking I read setting the big cluster or gold cluster to 1958 max helps. not sure I noticed alot of difference. No reason to mess with voltage,
All the ones I tried NONE affected audio volume at all even though most have options for it.
Flash kernel works fine seemed to boot fast, no reboots issues. Same version has worked on the last months of changes , has noop,deadline, cfq,bfq, and maple)
Franken worked fine also, I/O has noop, deadline,cfq,bfq,
EX Flar2's worked also (though the version the app gets you dont see on his download page) has a few more features (i.e. more choices in governors , I/O options)
Madys and singularity booted but had different issues. one had stuttering on the sound the other alot of pauses. Alot of options. Long boot time also compared to above mentioned ones.
Blu_spark didnt boot on my latest nightly. And I used his custom R11 version (newest I saw on his download page on XDA) Really want to try it out but didnt boot. Will play more with that and try again later.

Also, EX kernel manager, KA-Mod reborn, and kernel manager for Franco Kernel all worked on all of them,
KA-Mod lets you rename your device in the app (that you can do elsewhere in the rom also, ) so your phone shows up on bluetooth with a unique custom name.
Franco Kernel Manager has per app profiles, light color shift for night etc, and ALOT of tweaks and even a page to suggest other apps to improve batter life. I paid for Franco and that is what I am sticking with. If you run Franco's kernel it will update and flash it for you
EX kernel manager also will update and flash their kernel.

[Discussion] Favourite Kernel and Why ?

We have another post for ROM. Why do we not have another post for Kernel ?
As we can see, we have more than 5 kernels that are from XDA developer or someone else. But which one is really good for your ROM and which one still keep updating ?
I have been using OP5T for 2 months. Have used so many kernels but i still got stuck in those and do not know which is more stable. I am planning to use the kernel from Blu_Spark. Is that good ?
Post your favourite kernel and tell everybody why you use that. It will help newbie to pick what they want.
I am using Flash kernel at the moment but I have already tried Blu, franko, arter, ElementalX etc, but honestly for me it's difficult to see any difference since this phone have already a great battery life and great speed. On my previous phone (S8) the custom kernel gives a big advantage since the phone have tons of bloat and and isn't running stock like Android.

I have tried Blu and Franco for now and both have been very good. I really think kernel performance depends on the combo with the ROM as well as your device. I'm on Liquid Remix with Franco currently but I may give Resurrection Remix a try with Flash. If I had more time, I'd flash every ROM with every kernel to get a feel for all the possibilities LOL. :good:
For me Franco and flash kernel are the Best.... Now with ob3 with Franco kernel

Did the Franco improve battery or performance? Someone Tried the Boeffla?
At the moment, both Flash Kernel and RenderKernel are great options in my opinion. I have tried most of the other kernels on xda and if you are looking specifically for smoothness/speed, these are the two you should test first. I do not run battery cycles; everyones daily use scenario really differs too much.
Flash Kernel currently has some kernel features I need (Kcal support & wakelock blocker) while RenderKernel does not have these features quite yet. While it lacks in some features, RenderKernel is undoubtedly the smoothest kernel for 5T right now.
I am on a 5T with OOS 5.0.3.
I like Franco but recently some custom ROMs have WIFI cannot turn on problem after I flash Franco kernel.
:fingers-crossed:
(Don't blame any devs here just sharing.)

I haven't really played around with Kernel choices much.
I use and appreciate the professionalism of ElementalX kernel.
With it's options to adjust for extreme brightness, it quickly became a favorite a couple years ago and I've just stuck with it since.
Now most devs are adding high brightness to their kernels.
I guess I can start checking other kernels out.
I do like that ElementalX stays very stockish, reliable.
I can pretty much flash it and feel confident nothing weird will pop up over the next few days.

ElementalX, Franco, and flash were all my go-to kernels back in the 6p days (just a few months ago, lol), so it's hard to pick, especially since they all ended up on the 5t. Right now I'm on exkernel though I am partial to flash. Battery life is amazing on all 3, but the overclock on ex just adds that extra bit of smoothness that I've never experienced before. Call it placebo but I just love this kernel (exkernel).
any more input?
im curious to know if fsync affects battery performance at all, can someone also test this out if you are on a kernel that enables disabling the fsync feature

Tried it but didn't notice any difference.
Technically it should improve performance when using the phone, but it won't be noticeable.
boeffla
simple and steady, close to stock for daily using.

Does flashing a custom kernel solves Google play services battery drain?
Do I need custom recovery and root to flash a custom kernel? I'm not willing to play with kernel adiutor so I'm not really interested in rooting

Custom kernel has nothing to do with google play services. You need custom recovery to flash a kernel, but most kernels for op5t are "flash & forget" which mean there is no reason to change the setting of the kernel.

maybe not Google play services specifically, but with my latest phone (zuk z2), kernel was directly related to deep sleep
stock OOS/kernel has a serious issue with Google PS in terms of deep sleep. Besides that, I dont feel any need to flash a custom kernel. SOT is incredible already, and performance is really fluid.

If you are OK then there is no need to flash a kernel. If an app is crap (like Google services or facebook) the kernel can't do miracles and its not kernels job to control wakelocks of user apps

I keep changing between blu and new kernel
Not sure which to stick with but I think new kernel gives me a bit more battery
