I'm up to version 7...
Since then i've added options for delay off (ie you switch the screen on right after the screen goes off) now it gives a grace up to 15 seconds
On reboot, the service uses just 3-4meg of ram!
Remote control via SMS, enable gps/wifi/etc via on/off commands this then allows apps like where's my droid to accurately get your phones location, lost or stolen!
Where's my droid can't enable gps/3g etc without it, it may fail even if it's outdoors! This app solves that issue...
Makes your battery last longer
Charges faster
Phone runs cooler as a result
Keeps battery power reserved for as long as possible in emergencies
As electronic experts you guys know that hardware costs you in battery, wifi, gps, 3g, bt all cost precious ma... kill the hardware and save the milliamps, it's that simple...
Other apps kill background services but most if not all will get rerun and continue to eat power up...
Unfortunately, even though it now supports 100% hardware for 4.4 and 5.0, you must be rooted to access the system shell to turn these hardware services on and off...
