   echo bq27000-battery.0 > /sys/bus/platform/drivers/bq27000-battery/unbind
   modprobe platform_battery

allows me to check the value of:


and using:

   rmmod platform_battery
   echo bq27000-battery.0 > /sys/bus/platform/drivers/bq27000-battery/bind

restores the "smart" battery function.

I attach a graph of the resulting discharge rate of the fully charged 
Nokia BL-6C battery.


- Even with the "dumb" battery configuration, the battery charging 
animated icon continues after USB (power) disconnection - should that 

- Using the methods above, both "bind" and "unbind" files exist in the 
driver directory - shouldn't there be only one at any one time?  If not, 
don't the files only need to be created once instead of repeatedly each 
time the scripts/aliases are run?

- The discharge rate attached for an inactive phone (with a blanked 
screen) with a new, fully charged battery is not very good (~10 hours) - 
I would need at least 24 hours with light usage to be able to use the 
Neo as my regular phone.  Is this battery performance typical?

- Should the phone be shut down after the "dumb" battery is fully charged?
