I would like great battery life. The main problem is my phone always overheats and drains battery all the time. Don't know why my phone is overheating like this. :(
[Galaxy S 4 i9500 Android Development] Rohi09:
Okay do this, your performance will be a little low though:

A15 1000mhz, decrease cpu voltage to 100mah global, gpu freq to 350mhz and volt reduce to 75mah, reduce memory interface voltage control to 50mah, enable power efficient workqueues on cortex brain, reduce touch boost for both cpu and memory according to your likes (mine is 200 for all in nominal, 400 for medium and 800 for high), LMK profile agreesive, entropy to 1, power suspend to userspace trigger and 1 (enable), and if you want, enable registry hook (I don't do this, causes problem sometimes to me)

Hi, thanks [MENTION=5592093]VoLTaqe[/MENTION] for this kernel.

I installed as described at tthe first message, but everytime i open synapse app, the same "understood" notification pops up. Is this because my settings are not saved? or any different thing happening. Any info would be great.
[Galaxy S 4 i9500 Android Development] robsonsilva:
Click save. Then go to Settings and uncheck the warning of instability.
[Galaxy S 4 i9500 Android Development] Venomz33:
I assume that you mention "understood" button as save. So I clicked and untick "stability check" from settings, but when I restart phone, if i open synapse, same "Boot settings cancelled" message pops up again.
[Galaxy S 4 i9500 Android Development] KHEMS91:
Audio output in speakers is only one channel, and when i mix the stereo using synapse then it's apply earphone output too....

What can i do plz help me.
[Galaxy S 4 i9500 Android Development] robsonsilva:
Weird. Try resetting the synapse and see if the root permission was granted.

your kernel is great, everything perfect

But...

Speaker output is only single channel, not mix of both stereo left and right.

Plz do something for this issue...
[Galaxy S 4 i9500 Android Development] danveer:
Volt just 1 question,

The what does dissabling those wakelocks do?

It only says that it major wakelock etc but what wont work if we disable them?

Like of screen downloading etc, sync etc

Sorry if i sound silly

[Galaxy S 4 i9500 Android Development] white7561:
Yes. And restore only the boot [MENTION=5592093]VoLTaqe[/MENTION] u may make the default A7 freq max to 1.2 and the A15 1.6 if you dont do that already. It may fix the reboot prob because the voltage doesnt enough and such.and the gpu max to 532 for stability :)

just hope fc gets fixed in next update
[Galaxy S 4 i9500 Android Development] Mango Polo:
that is weird you all guys get FC's on so many apps. Being on 2.2 I don't get FC at all. Everything works flawlessly. Maybe because I use a clean ROM without any UI modifications? Prism BB v16

--------------------------------------

Edit:

After 2 minutes I wrote this post, I got my first FC for today since I got 2.2 for 7 hours already. Contats app FC now. But the rest is still fine. Gmail is ok, Chrome is ok, all is ok.

I guess it just randomly FC's apps time by time

[Galaxy S 4 i9500 Android Development] ilya39:
Using 2.2 since it's release with sunrise rom, no fc at all, everything's as good as it have to be ;)

Just one question,i've seen a "number of cpu's available" in synapse, that means only a15 core or a7 too?
[Galaxy S 4 i9500 Android Development] Aayan 123:
So new version has fc Problem?
[Galaxy S 4 i9500 Android Development] VoLTaqe:
v2.3 out by the way.

Good to see that. Thanks mate.

Thanks for positive comment. We have 4 cpu core you can control which ones actively working others will be disabled. So you can save battery but this maybe affect performance. I recommanded to you default for performance but if you want battery friendly you can change max core number to 2.

I didnt face any fc from my phone. Try and report back with LOGS

Thanks
[Galaxy S 4 i9500 Android Development] ari25:
Haven't had any fc either. On Aurora 7.0 with voltaqe 2.2.

P. S looks like we have a new version already. Time to flash gingerbread (2.3)
[Galaxy S 4 i9500 Android Development] VoLTaqe:
This wakelocks disabled by default already, so if you didnt get any error you wont get in future. My only concern was about shealth

because it need ssp wake but no one report about this i think working without wakelock too. I cant check because i dont using shealth.

Sorry my friend i didnt get what do you talking about. If you explain more detailed i can try fix. By the way i dont thing any failure on audio control because everything working good on my side. Dont forget play with equalizer settings. Maybe your problem because of this option already disabled by default or anyother 3.party app like viper or dolby wrong settings. And if you tick mono mixer phone act like that too. Hope you can find your solve.

by the way im getting perfect deep sleep time with latest and gcm disabled. Only awake time when syncing tasks other than always deep sleep. I will try improve sleep time more. Thats see what will see..

Please follow post 3 for reporting anything. It depending on governor or background apps.

Erased the data and settings of synapse. All settings are Left standard , just put 2 cores. After a few minutes, again shows 2 active cores at maximum frequency.

[Galaxy S 4 i9500 Android Development] VoLTaqe:
Confirmed. Some driver effected cpu for increasing freq to highest after deep sleep. I will look into it after tomorrow for now stick your max freq to lower one or use 4 core online.

Increase battery voltage values on synapse. Im using stock values on my source but you can increase that values with synapse. Because of we are using CUSTOM kernel :)

[VOLTAQE KERNEL 12.6] WITH [DARKLORD S6 PORT ROM 5.0]

Auto reboot problem
[Galaxy S 4 i9500 Android Development] VoLTaqe:
Without following 3. Post bug reports ignoring and will ignore too.

Clearing synapse cant revert stock settings, you have to reflash kernel or turn all global settings to default with synapse. Dont forget synapse only changing kernel parameters so if you delete synapse, your config will be still there.

Your problem seems too much underclock cpu and gpu going too high levels because of this. Every gpu freq have different mif values so it is crashing when gpu going to higher levels without correctly.

Brightness controls dont working on s6 port roms because lib or frameworks files using s6 parameters without s4 brightness parameters. So i cant do anything.

Screen flickering. .. i see that my phone has software related screen flickering. This screen flickering was better in 11.3 version of kernel. It occurs just before the screen goes off with phone unlocked.. but the same flickering doesn't occurs when phone is locked.. your kernel gave me a hope that it is software related.

[Galaxy S 4 i9500 Android Development] kapazo:
If we can limit a7 core up to 700mhz max and a15 from 800mhz to max i think it would improve battery life.

bacause a7cores at 800mhz use more volts than a15cores at the same speed
[Galaxy S 4 i9500 Android Development] danveer:
A15 takes in more power

Voltage is just 1 variable to the equation

V=ir

P=I^2R

THATS FEW OF THE FORMULAS, i wont go too deep...;)
[Galaxy S 4 i9500 Android Development] asad007:
In stock sources,

A15 start at 800mhz while A7 is max at 600mhz

[MENTION=5592093]VoLTaqe[/MENTION]

The lowest freq in exynos cpufreq is of 500mhz (default L8) but kernel adiutor reads it as 250mhz ,why?

Also if a7 is limited to 600mhz (in ikcs) then how does allow a7 to 1200mhz (or higher) work ?
[Galaxy S 4 i9500 Android Development] danveer:
Happy new year guys. XD

---------- Post added at 01:51 AM ---------- Previous post was at 01:49 AM ----------

Every software except synapse reads a7 freq at half of what they are

250 means 500, 600 means 1200

Thats how the big little works

100 to 600 a7 and then 800 beyond a15

Note- a15 freq is correct and needs not to be halved

Thats why we can max overclock our a7 to 1500 mhz, i.e. 750 mhz coz after that 800 will come and that will be a15 stepping in
[Galaxy S 4 i9500 Android Development] VoLTaqe:
Because of in 5410 cpufreq table has a7 freq list which one coming after before other than ikcs has reading which freq last of a7 and going first a15 step. If you want modify edit both files with editing max min sysfs or make a governor about it.

12.7 butter smooth. No glitches. 2 reboots, but i think that's coz of too much undervolting of gpu by me. Halcyon core with xposed. Loving it. Thanks.

One question for voltaqe. Is it possible to save all the synapse settings into kernel so that kernel boots with the synapse settings? At present kernel boots with default values then synapse applies it's values. Is it possible for the kernel to boot with custom values itself?
