Help me: Need maximum battery time

I need maximum battery time. So what is the best kernel for this and it´s configuration? I don´t need answers like "search for it" . Go hell those stupid guys.

there is no such thing as perfect kernel or perfect configuration,
the factors that can determine the amount of battery usage depends heavily on the nature of the usage under the user itself,
most kernels with undervolt support and underclocking will do fine,
i'd suggest you try out tweaks and preferences yourself since no one can guarantee you an exact time frame,
but i'll give you mine,
ROM: WP8 Monochromatic 5.1
Kernel: Built-in rom (savie's)
Tweaks: Built-in rom
Scaling freq: 156min 624max
CPU Governor: ondemandx
reduced all bloatwares even gmail and maps,
Battery Time (heavy usage): 4hrs max (medium usage): 1-1.5 day max (minimal usage) 2-3days max
that's just about it,
please take the time to conduct a research on what is your best prefered battery saving method,
don't call anyone stupid,
it's bad and potato disapproves

Rom doesnt matter really if you manage the applications well.
Use kuros kernel + kuros tweaks. Thats the best battery saving combo Ive tried.
For governor, use ondemand, the most battery efficient governor and use deadline for i/o

Not really. Change between Merruk #206 and kuros latest, you can really notice the battery drain difference. Its battery efficient than stock kernel in my tests.

Here u go:
Before all id reccomend updating the software to the latest version xD
Use the latest white kernel
Use v6 supercharger and some other tweaks
Reduce the screen brightness
Lower the system volume in the sounds options
Disable animation
Disable auto-sync
Disable backup settings
Disable roaming ^^,wifi,mobile internet,bluetooth when you dont use it(gps even if turned on allways is only actually active when theres a open app that uses gps ^^)
Disabling more sound effects will make it ugly and not cool lol,so do as u wish with thease:
Keyboard sounds
Lock screen sounds and vibration
set a boot frequency in set cpu like:
312-832,conservative,sio
Set up proper profiles in set cpu like
Screen off
312-312,powersave,noop
Charging
312-832,ondemand,sio
Battery 50 F
312-832, conservative,noop
Battery <16
312-832, conservative, noop
here just take my setcpu profiles, i made it in setcpu 3.07 just put it in the root of your sdcard and in setcpu enable profiles and click on restore profiles and click on that

Here are some build.prop tweaks
ro.ril.power.collapse=0
ro.ril.disable.power.collapse=0
dalvik.vm.heapstartsize=4
dalvik.vm.startheapsize=4
this one is alredy in v6 supercharger ;P
pm.sleepmode=1
remove some useless apps that u dont use but their allways running in the background(yeah remove anything u will never use)
Google maps
email(not gmail)
software update
and buying a new, better battery isnt a bad idea too ? is it (obviously xD)
I hope i Helped, this and some of my other build.prop tweaks made my battery go like lol xD it was lasting so long idk how much was it

Thank you all! Thanks so much guys!:good:

the correct one is "dalvik.vm.heapstartsize". dalvik.vm.startheapsize is not exist. nevertheless, this script only work for ICS. GB based rom doesnt have these prop. please be carefull with any prop for virtual memory like this one. if you clean your dalvik-cache you might ended up in bootloop.

Lots of information.
Thanks guys.

Changing GPU Frequency (using motley kernel)

Evenin all.
I have just flashed the motley kernel to my nexus 7 and have been able to change the cpu speed to 1.6ghz but am comming up blanks when figuring out how to change the gpu speed? (i have searched everywhere and cannot see how people do it?)
the only tip i saw was to explore the root of my device and go to sys/devices/system/cpu/cpu0/cpufreq and change a value in a gpu_oc file however there is no cuch file anywhere only cpu files.
anyone have a clue as to how i can change my gpu frequency?
thanks all.

big question.. has motley enabled the ability to change/edit gpu speed. without him enabling it, theres no way to change it. not all developers enable changing gpu speeds in their kernels.

You can run Trinity kernel and use trickster mod (app) to tweak your CPU and GPU to whatever you want.

[Q] System Tuner Settings

You can search all you want and still come up short, I'm trying to use system tuner to change the cpu and gpu settings and I cant find any help on how to use this app. Im running the latest Kaos Droid rom for 4.1.2, the latest Motley kernel and twrp, props to all developers:good:. Im looking for what the optimal settings are and how to use system tuner to change them. Can someone tell me or show me the right thread that can help? Im not sure what the min/max cpu settings should be and I cant seem to find where to change the gpu settings. We are all noobs at some point. I just want to beef my nexus up a little, nothing crazy.

aww for real?

I wouldn't use system tuner for this because it doesn't have the ability to change the GPU speed. I'd recommend TricksterMOD which is available here for free. Depending on your kernel (not sure if motley's kernel has configurable GPU now, it didn't when I used it) you can change different settings. It is personally up to you how you want to configure your device and change things depending on how it runs. Anyway, I'll give you an idea of my settings that I have changed.
CPU - Governor is Interactive (my kernels default but another alternative would be ondemand) running @ 102mhz min - 1600mhz max
IO - Governor is deadline (again default but imo the only one you should use) with cache at 1024.
GPU - 600mhz
VOLTAGES - My kernels defaults.
Make sure that you set the settings to be applied at boot (I use a delay of 1 because it didn't seem to apply without it) and also make sure your kernel has the powerHAL fix included, or else (in the case of trinity kernel) you will need to download this file (this is for Android 4.2.x). This will allow your CPU overclock to stick and not be reset to stock.
Hopefully this helps! But again, just play around with your frequency's and maybe look into voltage tweaking to get your personal balance between performance and power consumption. And if you are going for performance, I'd look at turning off fsync and using the ext4 mount script to boost your I/O dramatically (this will result in things such as faster app installs)

smt8544 thanks alot man! now I can start somewhere, I didnt wanna do anything stupid without some knowledge, I appreciate it!

Cpu tunner guid for noob ( --> me )

Hi
i found CPU Tuner app
https://play.google.com/store/apps/details?id=ch.amana.android.cputuner&hl=de
but i don't understand, what Settings are good
can you assist me ?
I found some guides, but they look not very good
Thanks

well ..
One option is to study/read the kernel threads in the android development and original android development nexus 4 sections - you will learn about cpu tuning from the kernel developers themselves. Many of them make specific applications for tuning their kernels.Thats how I approached it ...

I seems like it is mainly based on governors which generally change cpu frequency ramp up times and what kind of demand is loaded to cpu itself. So if you are not a pro about configuring kernels I advise you to flash franco, faux or some battery saver kernel and use their defaults. As I'm still a newbie I did modify cpu voltages and select "interactive" governor and it seems fine about battery life, but best way is; you need to read about kernels it may be dangerous also to play with hardware settings.

Help regarding Franco Kernel Manager?

Just downloaded the latest version of franco kernel manager 6.1. Im a total noob in terms of using this tool, so I've been looking for a guide or a tutorial that can assist in using it. Also what is the method of flashing the franco kernel from this tool? Where can I download the franco kernel.zip? I have been looking all over, cant seem to find it. Plz help
Im currently on RR Rom latest version 8.6.3. Im looking for a setting to enhance battery life and overall performance of the Phone.

Hey there
What I did to get Franco kernel was flash it during my first time rooting (so it was a clean flash, as the phone had be factory reset). Once you're in TWRP, you flash Franco kernel and then magisk. This is one way to do it. I can't advise you to flash a new kernel without clean flash because I personally didn't do it and I don't know if issues will come from that. If you can do it, my personal advice is to just do a clean flash. You know the drill, wipe system data and that stuff > flash ROM > Kernel > Magisk, and done
As for where you can get the zip, there is a thread here in the OP5 XDA forum on ROMs and Kernels I think and that's where franco posted the kernels. He's got a website too linked in the same post
HOWEVER, he hasn't updated them since last year, and I don't think they have support for Android 10, only 9
As for settings, well, in my own experience, you won't get any noticeable boost in battery life or performance without doing some drastic change.
If you want better battery life, you can decrease the maximum CPU frequency, change the governor to Conservative or Powersave, disable some cores, or all of those at once, but they WILL degrade performance, sometimes you won't notice but then you'll try to load a heavy webpage on Chrome and then you'll REALLY notice it.
The inverse is also true. To increase performance you change the governor to performance; usually the CPU frequency is set to its maximum by default, and the cores are all enabled anyway so you don't have to change anything. BUT, keeping the governor in Performance will also keep the CPU clocks at its maximum, and that's going to drain your battery like CRAZY, plus it'll overheat it. Usually there is no practical need for this setting, but I use it to play games on Dolphin emulator since thats when I can actually make use of that performance.
A better alternative is to keep the governor on Interactive, which will scale up CPU clocks depending on the load (if doing light stuff, low clocks. Heavy stuff > high clocks). Otherwise, Conservative does the same thing but takes longer to use higher clocks, so battery is saved.
Always use 1 governor for all cores. Do NOT use multiple governors (example: powersave for big cores, performance for little cores) because that will cause instability issues
Also, if you make any changes, you gotta tap the toggle on it, which will say something like "stay on boot: true". Otherwise, if you for instance change your governor to Performance, and then reboot, all your changes will reset to Default
Personally I just keep my governor in Conservative and roll with the defaults.
Hope that helps ya

sorry for digging but I was loooking for solution..
just make a backup of present kernel (tuned with FKM) and then flash it from backup menu
I was trying flash with twrp, magisk, 'set on boot' at first and many other things but it was so simple, it's there all the time
