awsm kernel voltaq.

was using 10.1 on halycion rom and never faced and force close for gapps or reboots, hotplugging was working too.

well flashed 10.2 today and its fully stable.

i just wanted to confirm few things :)

1) in 10.1, there was a slider to set min freq for gpu, ( which i had at 177 mhz or something ) now i cannot see that anymore and min freq is set at 266 mhz. i couldnt see this in changelog so wanted to ask if this is normal.

2) conservative gov still not very stable but using your gov now ( voltaqe gov ) will see how it is for battery..;)

3) (' this might be a noob question') if i set min freq to 200, 300 mhz and leave the screen idle running synapse, to see cpu freq, i see a lot of jumps from 300 ( or 200 mhz) to 1400 mhz ( for a7 cores ) and back to my lowest even if i dont do anything, while if i set it to 400 or 500, it remains at that freq till i dont do anything or touch the screen. meaning there are no jumps at every 1-2 seconds. This used to happen in 10.1 too. just wanted to ask if those freq are stable for others? and why does this happen. ( note, i dont get any reboots at 200 or 300 mhz, its just that frequent jumps to 1400 and back may be bad for battery life so wanted to bring this up..)

once again tks for this awsm kernel..

p.s. fully stable.. no reboot as of now, underclocked, and undervolted. love it

Awesome battery life

I am not going to change or flash anymore.

this is the best battery life i ever got on this phone. after 5 hours still shows 18 hrs left, with 3g usage. surfing and facebook and whatsup (no gaming.)

never going to flash or change my current ROM and kernel.

the MBP v1 ROM and kernel Voltaqe 10.2.

SUPER WORK done my [MENTION=5592093]VoLTaqe[/MENTION]

Synpse configuration: CPU 100mhz minimum, maximum to 1200 mhz else all default.

no camera lag for me.

Thanks a ton bro. !!
[Galaxy S 4 i9500 Android Development] gio_b:
In synapse minimum is 200 mhz ,how did you get 100 mhz ?

Tks giovanni.
[Galaxy S 4 i9500 Android Development] yogi.306:
i dont know

The kernel auditor shows me and allows me to select lowest 100mhz..

the app restored by Titanium backup.

and when i taken backup of it. that time i guess i was having kernel version that allows 100mhz.

so i am not sure, whether its really 100mhz or kernel auditor just showing it as from restorred setting.

synpse shows 200 mhz, you are right.

anyway battery life is best till now...

good job by OP
[Galaxy S 4 i9500 Android Development] gio_b:
O.K. "kernel auditor" ,not synapse.

Tks giovanni.
[Galaxy S 4 i9500 Android Development] VoLTaqe:
Synapse shows 200 mhz because little cores showing x2 that means 100 mhz showing 200 mhz.

thanks for review happy about that.

1- I added again this option. Will be available on 10.3

2- conservative highly depends on usage so i dont say anything about it.

3- every freq stable. It jumps because other cores hotplugging. When 4 core working with 100 mhz eating much battery then one core with 1200 mhz so this is normal behaviour. So we called it hotplug.

Will fix asap

Best on tw ever.

I didnt change related camera so it isnt possible. Clear camera data and cache.

Thanks for review.
[Galaxy S 4 i9500 Android Development] ktouy:
Thanks for your help buddy but nothing seems to work ill wait till next update, so far the kernel works flawless.. The thing its that i need synapse to fix some flickering on my screen but nothing that cannot wait..

[Galaxy S 4 i9500 Android Development] fAIyaZ:
Is it stock rom? I am on stock, work perfect for me.

I have suggestions for u.

Plz clean install rom(wipe data,cache,dalvik cache,system,preload and even internal storage too if u don't have imp files)

Flash your firmware in odin

Setup your device

Power it off

Root your device via odin

Flash custom recovery(recmd:TWRP)

Reboot into system

Place your kernel zip file in extsd

Reboot into recovery

Flash your kernel

Then wipe cache,dalvik and preload in advanced wipe in TWRP

Reboot your device

After that optimization process is finished,wait for 1-2 minutes

Then install synapse and busybox too if you want to use 10.2.

After that most imp turn off your device set back relax for few minutes untill your phone gets cooler.

Then turn it on,wait for synapse boot to complete.

Go into synapse in settings uncheck stability check.

And then Enjoy.

Hope it will work. I have done this whole process only one time. Seens that i never have to flash it again.

For Performance:

Min freq 300 and Max 1800 MHz and set voltage for big core 2000/1900/1800 to 1225 mV ( if u will have rr change max to 1600 with stock voltage ) use interactive or performance governor ( Powersave mode OFF ) also in CPU Hotplug sched_mc_power_saving to Performance

For battery life:

Min freq 100 and Max 1400 ( or 1200 ) MHz stock voltages use voltaqe or ondemand-sec governor ( Powersave mode ON ) also in CPU Hotplug sched_mc_power_saving to Battery and Hotplug CPU Load to PowerSave

For balance u can use stock values.

I use this settings. Use on your own risc.

Flash custom recovery(recmd:TWRP)

Flash your kernel

Then wipe cache,dalvik and preload in advanced wipe in TWRP

Reboot your device

Then install synapse and busybox too if you want to use 10.2.

After that most imp turn off your device set back relax for few minutes untill your phone gets cooler.

Then turn it on,wait for synapse boot to complete.

Go into synapse in settings uncheck stability check.

One of them my girlfriend's overnight deep sleep screen other one using screenshot. Already unnecessary kernel wakelocks blocked and necessary ones limited without loss functions. So i cant do more from kernel side. Your problem must be google apps. Reduce google wakelocks or app wakelocks.

Kernel has problem about hotplug mechanism and cpu freqs other than no any problem about kernel and they will be fixed a few release. You need read more about wakelock and tweak kernel. You can get easily 1.5 day and 6 7 hours screen on time with loss performance but i dont prefer that. We have already performance and good battery combination ;)
