[Galaxy S 4 General] Shade5:
This GUIDE is aimed at users who want to REDUCE HEATING/TEMPERATURE & get LONGER BATTERY LIFE on all versions of the RR ROM

(It wont affect your AnTuTu scores much & you will be able to use your phone for hours without your battery, phone or fingers burning up)

​

NOTE: My tweaks are related to HARDWARE (CPU, GPU, IO & Screen) & not the software's power consumption​

PRINCIPLE OF TWEAKS: : [1] Undervolting the CPU - to draw less power & run cooler

All the below steps will only take about 5 minutes to complete (& another 5 minutes if you need to install the Kernel) :)

STEP 1 - Flash ALUCARD's Kernel V3.4.108 (if you haven't already done so) from here (Thank's to [MENTION=6082440]_Bon_Bon[/MENTION] for the latest Kernel & permission to use his work)

Boot into recovery & flash the Zip (just like you flashed your ROM) - you will not lose any data at all

STEP 2 (AUTO MODE)

If you wish to get ALL my Kernel Tweaks in ONE STEP simply download this file OR download the default.zip (you need to unzip it) attachment

Save it to the root of your INTERNAL MEMORY (see screenshot on where it should be - you may already have a file with the same name there - please delete it)

Now open sTweaks -> select the BACKUP OR RESTORE tab -> Press RESTORE NOW

Wait 30 seconds.....

Now REBOOT -> open STWEAKS -> CPU Voltage - click Check the CPU Voltage are same as below (to be sure the settings are active) :good:

ALTERNATIVELY:....... (Manual mode - so you are involved in what is happening :))

Open the sTweaks app -> CPU Voltage Control & put ON the CPU VOLTAGE MAIN SWITCH

Now set voltages as below:

NOTE: (these are for a PVS2 & above chipset found in over 90% of i9505's)

IF you face any freezing+lines on screen (it is because of others tweaks/settings - please stick to just using my Kernel settings)

IF freezing still persists it means you have a PVS1 or PVS0 chip - simply add +25mV to each setting if that's the case

378	kHz	750000	uV

486	kHz	750000	uV

594	kHz	750000	uV

702	kHz	775000	uV

810	kHz	812500	uV

918	kHz	825000	uV

1026	kHz	850000	uV

1134	kHz	875000	uV

1242	kHz	887500	uV

1350	kHz	912500	uV

1458	kHz	950000	uV

1566	kHz	975000	uV

1674	kHz	1012500	uV

1782	kHz	1062500	uV

1890	kHz	1100000	uV

Now go to the GPU tab in sTweaks & put on the " GPU VOLTAGE MAIN SWITCH"

Set GPU voltages as below

Level 1 895000 uV

Level 2 1000000 uV

Level 3 1100000 uV

Now Click on the CPU page & ensure ENABLE ON BOOT (Load all settings on Boot) & below it press LOAD ALL

REBOOT -> open STWEAKS -> CPU Voltage - click Check CPU Voltage (to be sure your above voltage settings are active) :good:

DONE ! :cool:

I've overworked my phone for >100 hours & done over 55 full CPU/GPU stress tests with multiple CPU & benchmark tools to give you these STABLE final results.

With Games + Downloads + Benchmarking + Other apps + CPU Monitoring was running the CPU reached just 62C (see it in the screenshot attached)

I also took 2 back-to-back comparative benchmarks using AnTuTu & got 27,000 (an overall drop of just 6% from the initial 29,000)

RAM performance increases (cooler & more efficient) while Runtime & 3D performance loses out a little but this won't affect you unless you are into hardcore gaming/too much multi-tasking (if so then please do not reduce the GPU voltages)

Do share your results & experience - Happy tweaking folks! :highfive: & don't forget to hit that THANKS:good: button :o
