LOL, I was about to post something similar. Even if it's been 8 hours since unplugging from the charger, if I see 75% remaining on the battery I don't think "wow, I have 24 hours left," instead I have a panic attack and think "oh crap, two hours and she's dead...where's the charger?" The really sad thing about this is that I'm really not kidding. Even with the extended battery the T-Bolt would only go maybe half as long and it has scarred me for life...lol! BTW, I have not one, not two, not three, not four, but FIVE batteries for the Thunderbolt!
