Hello guys,
It's my kernel for the SGS II.
I am very surprised with the battery life.
With my own experience (with Batista ROM, the best for me): The battery is still 100% after 8 hours sleep (wifi ON, data ON)
The kernel works very great. Stable, fast, no reboot or freeze. Tested with some roms. Stress test successfully done without reboot or freeze.
The kernel has these frequencies: 1204 / 1150 / 1100 / 1000 / 800 / 500 / 200 mhz. Compatible with SetCPU (auto detect).
For versions 2.2.0 and lower : there are 3 versions. Release Version, Workaround Version and Stock Voltage Version.IMPORTANT
For versions 3.0.0 and higher : there are 2 versions. Release Version and Workaround Version.
Try only Workaround Version or Stock Voltage Version if you have issues with Release Version.
You can install this kernel with Odin (in PDA) or CWM Zip installer (since 2.1.0).
AFTER the kernel has been flashed please calibrate your battery.
My goal: Battery life and Optimization.
More optimizations and options in the future. Kernel continuously updated.
<b>Jeffrey-SpeedFrey_Kernel 3.0.0</b>
This kernel is optimized and uses low ram. The boot is very fast and everything is very smooth and fast.
Impressive battery life while using your mobile phone.
FEATURES (for more details, look changelog) :
- Undervolted (CPU and GPU) (not compatible with the SETCPU control voltage because the kernel is optimized with my own values)
- Workaround version available (less undervolted)
- Stock voltage version available
- SetCPU compatible (1204/1150/1100/1000/800/500/200 mhz)
- BFQ-V2 Scheduler added and set by default
- 838 MB ram memory available
- CIFS support (cifs.ko and slow-work.ko automatically integrated in "/lib/modules")
- BLN support
- Vitalij's touchscreen fix (value : 10)
- Rooted
- CWM 4.0.1.4
- Interactive governor
- Disable some debugging options / look changelog (better battery life, better ram usage and smoothness)
- Some tweaks / look changelog (better battery life, better ram usage and smoothness)
