[TWEAK][Siyah Kernel 4.1.1+][Extweaks] Get up to 7 hours of screen usage
WARNING: Use this settings at your own risk. I am not responsible for what will happen to your phone.
So, Siyah Kernel 4.1.4 has been released, and since 4.1.1 and its new features I have struggled for obtaining maximum battery life without loosing smoothness.
I tested these settings on 5 phones (Galaxy S2 GT-I9100): mine and my friends' ones, and we all got the same (more or less) results: it's awesome!
Screen usage can get up to 7 hours. I did these tests with mobile data on for all phone usage, and not in deep sleep. When I was at home I switched to Wi-fi.
My ROM is AOKP M6 (ICS 4.0.4), other tests were made on Resurrection remix JB, stock XWLPF (ics), CM9 stable (screen usage: about 6 hours, no more), and AOKP JB (latest).
GENTLE FAIR SLEEPERS:
: Linux kernel defaults
CPU IDLE MODE:
SMOOTH SCALING LEVEL:
MAX CPU LOCK:
Dual core mode
- 50mV (if you get freezes, set -25mV)
CPU STEP COUNT
: 16 (all available)
MALI TOUCH BOOST LEVEL:
Step 2/Step 3
GPU STEP 1:
GPU STEP 2:
GPU STEP 3:
GPU STEP 4:
GPU VOLTAGE LEVEL 1, 2 AND 3:
GPU VOLTAGE LEVEL 4:
0 (set this value as you want and as you ears can stand it, it doesn't affect battery life unless you listen to music)
ALL OTHER SETTINGS:
mDNIe negative toggle:
set what you want, cause BLN is disabled
use ROM defaults
LEDS ON WITH TOUCH:
LED VOLTAGE LEVEL:
2700 mV (2750/2800 mV if led lights are dim)
DEFAULT I/O SCHEDULER:
ALL OTHER SETTINGS:
I think they are not too aggressive values, but if you get freezes, I recommend you reset your extweaks settings via CWM recovery and then use less aggressive ones.
In the attached screenshots, battery stats analysis starts from 91% since I had to restart my phone, and when it was at 10% I plugged the USB cable in to transfer a .zip file in my SD card, but I don't think that this 15-second charge affected my test
(I'm sure it didn't!).
Phone usage was high today, I used Tapatalk, created a new UCCW skin, did some long phone calls, Facebook, messaging, e-mail checking, and other stuff I don't remember since the battery stats don't even report them (lol).
Notice that this is an extreme test. 7 hours of screen usage is not a myth, reality instead, but you cannot get them with the so called 'everyday usage'.
Screenshots of test made on my usual phone usage will come soon
