Being relatively new to kindle/firmware, I looked into downgrading to an earlier version of the firmware but the device doesn't allow that....

Any suggestions or thoughts will be appreciated!

Thanks
There is now a set of KUAL buttons that will report the information on the CPU Control(s) in-use.

This report includes information that may be helpful to us in finding out the cause for this poor battery run-time problem.

The button-set also includes buttons that allow some control over the CPU speed (and hence, its power consumption).
