No, because
the battery is not trivially replaceable ;-) 
 Having graduated to the 16C from the TI "Programmer", one thing that
 struck me was that the 16C boasts a power consumption of 250
 microwatts.  Pretty remarkable for an early 80's design. 
 
That *is* pretty nice.
  An iPhone drinks what, a couple of watts? 
According to this,

the CPU draw is around 180 milliwatts; I don't know if that includes the
PowerVR chip. The 3GS probably draws somewhat less due to its more efficient
core.
