at this exact moment, battery eye is showing 90%, which is in-line with the phone being off the charger for a few hours. however the status bar animation still shows 100% full.
this disconnect appears consistent throughout the battery level range (i ran the battery down to about 20% yesterday to test it). the status bar animation is consistently 15 to 20% higher than i'd expect, given my normal battery consumption on PR 1.2 and the results from battery eye. so... battery life seems improved, but i'm having a very hard time quantifying it.
