I know, I know. Another thread about the Eris battery? But...this one is a little different. Yesterday, I decided to run the battery until it died and got a big surprise. As the battery meter goes down, it eventually goes to an amber color and finally red. I was amazed how much battery is still left after the meter gets to the amber stage. I was able to watch The Dark Night completely after the meter was in the amber stage. It died quickly thereafter but I gotta say, I was quite surprised at how much power is still available at such a low meter reading.
