Hey all. I am running the script on my phone but I am not too sure if it's doing its work.. I am getting close to three hours of screen time every time after a 100% charge..
Sent from my XT910 using xda app-developers app
I'm not surprised cause that's what appears to me as well. (both leaks .33 and .39)
So use my first upload in which this line is erased:
https://docs.google.com/open?id=0B1vV1mGH5rAOcW8wZ0NCVU8xVEE
+1 to all
I have to admit that your script is VERY EFFECTIVE! I completed 24 hours using it and my battery lasted 30 to 40% longer!
Great job!
Feel free to use my links for your OP if you want!
