I know there is a lot of talk about sub par battery life. I am learning to live with it and keeping the GN plugged in more often. now...I don't know if this is because I am using a smaller cap batt than on my TB (2750mAh), but this thing with the 1850 goes from 10% to 80% in 45 minutes!! I gotta say it charges more quickly than anything else I have owned. Does anyone else feel the same way or is this how it is with stock batts?
