Yeah.  I wonder if the battery has deteriorated somehow (from the
phone running and being plugged in to USB for days or weeks at a time,
and being overcharged? but the power management chip should not
overcharge it, right?), or maybe it is not being fully charged.  I
consider it fully charged when it has been running, and plugged in to
USB, overnight.  I'm also wondering if my hub may be limiting it to
less than 500 mA though.  I need to measure the currents... both
battery current and USB current, in various states.

Speaking of which, where can we get more batteries?  If it has not
deteriorated yet, it certainly will eventually.  The Nokia ones are
not quite compatible enough, are they?
