I think APM is a liar. On the way to work I was working on my zsh prompt and my apm status said 50%, 90 mins remaining. Then the z went to sleep. I turned it back on and it went to sleep again. Obviously it didn't have 90mins remaining. Now I'm here at work, I plug in my z and after 2 minutes it says 100%! Yet the orange charging light is still on. I know that it must still be charging, even my cell phone takes at least a few hours to get fully charged. Why is apm lying to me?
Not sure really, I get about 3 hours constant runtime from my battery, however, I do a calibration run every month or so, maybe this makes a difference.. basically all I do is charge it up fully and then let it drain itself powered up doing nothing until it hits forced suspend.
3 hours is about what to expect from a Z running OpenBSD because the Microdrive is constantly moving.
It sounds like you were getting the failsafe poweroff when your device was showing 50%... I would suggest trying calibration first then hitting firstname.lastname@example.org to see if anyone has any answers (Uwe will almost certainly be the one who can answer this).
