Reading the forums here there are discussions on removing/disabling the unused phone functions on the scroll to conserve battery life.
There was a tip in one of the threads that suggested that you could use one of the "Flight Model Apps" to achive this without rooting your device.
I have downloaded the "Air plane Mode Wi-Fi Tool" by daniel velazco and also the flight mode widget.
However even when the tool(s) are in flight mode the battery usage for "Cell Standby" still eats power away.
Am I using the wrong applications?
