Some report standby times of 2 weeks, last time I've only had 4 days. I'll run it down. No activity, just standby from fully charged (close) to zero.
It would be interesting of course to see your figures. (Even for other units than iRex 800. I'll do the same in some days with BeBook Neo.)
It's close to 24 hours now. I'm still above 90%. This would be absolutely okay, pointing towards 10 days.....
I'll keep tracking.....
