EXTEND YOUR BATTERY LIFE​

REQUIREMENTS

Most importantly your phone

init.d support (startup scripts during the boot)

file editor like root explorer

root access, busybox (rooted phone)

what's in init.d scripts?

4.1 cpufreq_governor

21cpufreq_governor script sets the governor that contorls the CPU's thresholds and sampling_rates

4.2 cpufreq_screenstate_scaling

31cpufreq_screenstate_scaling script defines the governor values and decides the actions based on the phone's state - conservative, ondeman, lazy, awake, sleep modes. I've changed lots of values from Calk's original script to save more battery power thru this script. As indicated in Calk's original thread for FD02, this script would not run if you have already installed some CPU control apps something like OC Widget, Quick Clock, SETCPU, and Android OC.

4.3 tweaks_GAURAV

41tweaks_kobridge script has almost everything in it to improve the network speed, sdcard tweaks, other battery saving tweaks, VM management, Kernel, wifi tweaks, etc. For some of the values in here, there are some overlaps with build.prop tweaks. So, if you do not apply the tweaks to the build.prop file, many tweaks would still work.

4.4 zipalign

zipalign is an archive alignment tool introduced first time with 1.6 Android SDK (software development kit). It optimizes the way an Android application package (APK) is packaged. Doing so enables the Android operating system to interact with the application more efficiently, and hence has the potential to make the application and overall the whole system much faster. Execution time is minimized for zipaligned applications, resulting is lesser amount of RAM consumption when running the APK.

If less number of applications with an unaligned home application, you’d see slower application launch times. This is the best case scenario. For a worst case scenario, having a number of unaligned applications will result in the system repeatedly starting and killing processes, struggling with lags and huge battery drain.

4.5 Wifi Sleep Wait timer

What this tweak does is, it controls the time until wifi sleeps after the screen turned off. By default, it's 15 minutes. So, even you turned off the screen, by default, phone will wait for 15 minutes and then turn off the wifi. By using this tweak, you will have the control over wifi idle time until wifi sleeps.

I HAVE FLASH THE ZIP BUT YET I DON'T SEE ANY IMPROVEMENT IN MY BATTERY LIFE (HERE IS SOMETHING THAT CAN REALLY HELP YOU)​

IN THIS PROCESS YOUR PHONE NEED TO BE CONNECTED TO CHARGER

1) CHARGE YOUR PHONE FULLY

2) GO TO DATA/SYSTEM DELETE BATTERY STATS.BIN

3) NOW REBOOT YOUR PHONE (YOUR PHONE SHOULD BE CONNECTED TO CHARGER WHILE REBOT)

(To any visitors to this thread,

Please Rate this thread based on your reading and tweaks that I provided. If the rate is too low, that means I'm doing a bad job in here! If the rate goes down below 4 stars, I'll stop providing these tweaks! So, please excuse me. Please don't rate this thread with the only reason that I do not provide the tweaks for your rom, which you are using! I'm using my own time for this just like lots of other users. Only the thing that makes me more happy and get focused on this would be your rates and 'thanks' on this thread)​

THE TWEAKS WONT WORK ON GB U WILL FACE MANY PROBLEMS AND LAGS​
