Hey guys. I heard from a lot of sources that the AAAA battery in the SP3 pen is able to last for a very long time, though I forgot approximately how long. But I'm still usually a stickler for saving battery life, and I'd like to ask for advice about that. I was told that the pen turns itself off whenever it's not used to about a minute, and turns itself back on when you press it on the screen. But I find this hard to be true because the battery is needed to be detected by the computer screen, and even if you leave the pen for a good while, the pen will still be detected on the screen if you put it near the screen. Would it help save battery life if I kept the pen open whenever I'm not using the computer? Because whenever I'm not using the computer, I do keep the pen open. Or would the pen be completely shut off whenever the computer itself is off, and that I don't have to open the pen at that time? Just how unecessary is it to open the pen, and how much/little difference does it make?
