how to overclock and gain maximum battery and performance

Hi everyone... i have samsung galaxy S I9000 base rom JVP 2.3.4 and CWM recovery 3... its rooted can anyone suggest me how to gain maximum battery and phone performance ...
which is the best Overclocking app
and wat are the frequecy to be set
please advice me how to gain maximum phone performance and battery performance...
Thanks in advance

wondering the same thing.
could any one give detailed instruction?

maybe u should try a based rom (JVQ or JVR) and a kernel (like galaxian EE or semaphore ) + JVR modem

Use odexed JVR on latest galaxian kernel, there are good odex themes (I use EE SP1 clocked to 1.1ghz via tegrak. This is a minor OC but voltage at 1.1 is lower than standard 1.0 ghz!) remove all the crap bloatware (I remove loads of stuff and all samsung apps using sgs chlorine) use zeam launcher (fast, lightweight). Use setcpu for screen off profiles and also juice defender.finally, convert to ext4 then back again to rfs to clean file systems. Then calibrate battery, use noop scheduler. This will give you a very fast phone with great battery life

thanks a lot dude let me try will hope this works fine

gsw5700 thanks for the sugession ... but i am confused wen i check for this kernel .... http://forum.xda-developers.com/showthread.php?t=1196391
it says flash it if u have ODEXED JVR ROMS only!!! but my rom is JVP
please let me know how to go further and also let me know is the camera application is stock galaxy or hacked camera
thanks in advance

Flash odexed JVR, then you can flash this theme (that I use). Then flash chainfire 4.1 kernel to get root, then flash latest galaxian kernel. Use setcpu and juice defender to get good battery savings
Don't forget to hard reset/wipe after flashing jvr, tick to re partition, wipe both caches and fix permissions after flashing galaxian

thanks dude i have followed the procedure... let me check the performence

it gave me 16 hours of battery life .. and performance was stable

Why not just stay on ext4?

RFS will defragment after a while (depending in usage), I like to defrag file systems every month or so. I haven't actually tested it, but hope it will provide additional benefit. I also like to use it for a while whilst on ext4 to prove that ext4 doesn't feel any faster at all than rfs!!

I also suggest Galaxian. It's pretty neat.

So how long battery life do u guys get on undervolted galaxian?
Im on JVR w/ talon kernel OC'd to 1.2 and UV'd and i barely get 2 days of little use.

Because some kernels don't need any lagfix actived

It's not about fixing lag, that is just terribly outdated but traditional terminology.
RFS isn't slower than ext4, but the letter is still the better filesystem by it's journaling and fragmentation behavior.
In a nutshell: you don't have to convert to ext4 to have a smoother device, but you might still want to do so if you want a better file system running your device.

I get about one day of medium to heavy use and a day and a half if I don't do much. I lose about 2-3% battery over night (using juice defender)

my signature tells the setup. undervolting for the lower frequencies helps. Also check out Zach/picachu's screen state scaling and system scripts. Combine with the latest talon kernel and you are set. Tegrak aop is optional for overclock above 1200

[Q] best rom for speed

Hello i have a rooted nexus 4 and i want to install a room on it but i don't want rooms with too much features but i want a room that will give me a better speed and battery life
Thank you

So... stock?

The rom doesn't really matter, its the kernel that makes a speed difference. Browse thru the kernels in android development section

I read about pure speed x rom ( psx ) but i wanted to know if there's a better rom

All things come at a cost, so desiring both insane speed and insane battery life might not be possible... But, if you're looking for a lot of speed and decent battery life, here's what I've done:
1. Download and nstall the most recent 'codefireXperiment nightlies', which you can find here: http://downloads.codefi.re/synergy/codefireXperiment-Mako/nightlies/mr2. (Y'know the whole shebang, GAPPS are to be downloaded/installed as well)
2. Download and install the latest Faux123 kernel for JSS. Look at his first post for battery saving settings that you can use with Trickster Mod.
3. Download and install an app called Greenify from the Play Store + download and install either FauxClock or Trickster Mod from the Play Store.
4. Profit

as suggested above : update your kernel indeed.
Did you upgrade to JRW66Y first ?
Be carefull to choose the right kernel version : JWR, not JSS ones.

I'd suggest you to use Paranoid Android's latest build with AK kernel and Nova launcher.
Set CPU governor to interactive and GPU to ondemand. You will have very decent battery life and great preformance.

[GUIDE] How to get max smoothness from g3

Hello i sperimented everything on my g3 to get max performance and battery life, these are the guide to get max smoothness for g3.
First i use an aosp rom 5.1, then flash 777 kernel and download kernel adiutor and open it, and go to cpu settings and set cpu governor smartmax,then these parameters, then go gpu settings and set others parameters, if you got green screen dont edit cpu boost interval sync threshold.Enjoy best performance and battery life for g3.
update.tdt removed because caused bootloop for some, just tweak the smartmax governor and gpu gov

Could you experiment how to get smoothness and better battery on cloudy rom? [emoji4]

What sort of battery life are you getting? And could you please provide a bit more information on how this improves performance over standard CM/AOSP and stock ROMs? Thanks for your effort!

just flash a custom kernel like chupa chups or rin and see if it has smartmax governor then you can follow the guide

I got a bootloop flashing your TDT tweak zip
How can I solve it without wiping data? Installing the rom over again has no effect, and wiping cache/Dalvik neither. I'm running multirom and I just booted in my other rom (stock based).

Same here... Got bootloops with TDT. I had to reflash everything

for me was working, btw i have removed tdt script just tweak smartmax gov and gpu gov ify ou got green screen on editing cpu boost interval threshold(like me in fusion rom) just dont edit it :good:

Yep i got the green screen as well on blisspop. I applied your other settings though. Will report on the improvements after a few hours of usage.

hi there , so happy to see kernels for s3 neo !
how can i know that my phone is EUR version ?

Settings -info and see if is 9301i or other version.if it's gt- i 9301 i you can flash it.
If anyone with a 9300i (dual sim) could send me a link to download only the stock boot.img?

@sev3n1985
I have one problem with this kernel, i used it for five days, first three it ran like a charm, battery good, perfomance was awsome ect. But the past two days I've been getting battery drain from Kernel (i used GSAM Battery monitor to see) about 30% from Kernel(Android OS) is draining my battery, and after that comes Android System with 20%. Is it possible to fix this or is this normal ?

tell me:
- governor you're using
- sched
- logcat to see what's wrong.

No need i guess i fixed it, now it's not draining that much just did a factory reset, now its on 15%, battery is now ok, currently I'm using Alucard, it's the best, besides it seems when i changed to alucard everything went to normal, u guess ondemand was giving me problems or i dunno

Don't use ondemand, is the default gov and is bugged, use intellidemand

What's the diffrence between first and second download link ? First link is overclocked experimental version or what ? I can see first link GT-I9301I_EUR.tar is posted 2015-07-06 but the stable (v2) is posted 2015-06-06.
I think i could just unpack one of the above packages to extract kenrel.img and just flash it via flashify app

kernel
available for S3 NEO android: 4.4.2

now the kernel is flashable from recovery?

init.d isn't running
I don't know if I am the only one having this problem. when i installed this kernel it enabled init.d support but if i put any init.d script it doesn't run on boot then i tried universal init.d enabler but it didnt work. except this problame everything is working very well. and sorry for my bad English.

Hi @sev3n1985, is it safe to use CPU at 1600 MHz? However I use intellidemand for CPU, simple_ondemand for GPU and ROW for I/O and it's super as far as I can tell. It put's phone into deep sleep, over night my phone hasn't lost a single % of battery :good::laugh:

1,6ghz is the max frequency for msm8226, I suggest to not use always at this frequency, maybe use it only when you need it (i.e. gaming).

Hello. @sev3n1985 I have a question. ..
We almost have TW5.1.1 for I9301I and I9300I - can you tell me that kernel is compatible with TW5.1.1 or can You make the kernel for TW 5.1.1 in your free time ..?
Thx for your work.
Greets

Sorry but after I flashed I can't change any frequencies any help?

Please?? Any body who has an idea?

Can I ask a question? Can someone send me a link where I can update my phone? I have s3 neo

What is the most battery friendly CPU governor? Smartmax or Alucard?
And another question: Do I need PowerNap to have my phone in deep sleep mode or the kernel does that by himsel?
Thank you, in advance

[HELP] Which ROM is fast and stable with good battery life and most closest to stock?

Hi just want to know which rom is fast and have a good battery life and closest to stock with stock kernel also what do you recommend me?

Depends on the S5 model. There are over 40 variants.

Flash stock rom, root, flash custom recovery, remove bloats using titanium backup,flash custom kernel beofella done best stock rom for me lol...
Phoenix rom i guess

I second that. Stock Marshmallow is excellent once you remove the bloatware.
If you want to make it even better I recommend Boeffla Kernel (boeffla.de) – ATTENTION IT IS JUST FOR G900F! It has a very easy to use configuration app and ready-made profiles for battery saving, undervolting etc. Just remember to take it easy when undervolting, start small with -25mV, run the Stability Test app a few minutes, see how it goes. Usually -25mV should be more than enough. In fact I'm using one of the Boeffla profiles that does exactly that, -25mV on the voltage and limit the frequency to 1.7GHz and I was getting 0.2% battery/hour in idle. (On a fresh install without any apps yet, granted, lol.)

based on stock mm, great bat life, imo try SUPERLite MiNi MM *361mb*
