did a few more tests and this is what i found about SmartReflex.

the setting seems to have no effect after a bit of heavy usage on the phone. simply refreshing the setting by issuing the 2 echo commands just PRIOR to putting the device to sleep causes some pretty dramatic effects.

let the screenshots do the talking.

the first screenshot shows the full effect of smartreflex just before i put the device to sleep. incidentally, i have the device set to offline mode (no gsm connection, no wifi - basically flight mode). i've highlighted the section in dark red.

the second screenshot shows the battery drain that i normally experience with the device in sleep and in offline mode. i've highlighted the section in orange.

the third screenshot shows my first experiment with smartreflex where i accidentally discovered this behaviour. you can see the battery continue to drain like normal for about 2 hours and then suddenly the battery graph line becomes almost flat. i've highlighted the section in yellow.

here's where the interesting bit starts (which makes it questionable): if you look at the first screenshot, you will notice the battery charge actually increasing all by itself twice (once at around 1am, and again at around 6.30am to 7.30am). there must be some recalibration going on in the background. also, from 6.30am to 7.30am, i had the phone in online mode (2g gsm only, wifi enabled but not connected to any wifi network, and no gprs/3g connection).

i will continue to run this for a few more days and observe the results. if the battery line continues to stay almost flat with this method, i'll be very happy indeed. it's time to script this up.
