I am also moving away from the "bump charge when I can" mentality that was a necessity with the E4GT. Now I can charge it overnight, which gives me plenty of juice to make it through the day with battery to spare, then charge it once at my desk before I leave work, which gives me enough juice to make it through the night until I go to bed. Before I even got my E4GT, I bought 2 backup batteries on ebay. I haven't gotten around to buying even one backup battery for the Note 2. It's not a pressing need.
Oh yeah, it's been over a month now, and I still haven't heard the low battery warning.
