Some interesting data:

Also, what is often not discussed is that is seems a reboot affects the power 
meter itself (either via some battery chemistry effect or some other 
mysterious way) so you can get inconsistent readings - I have theoreticeally 
lost ~30% of capacity after a reboot (which is not physically possible 
without melting) and on another occasion I ended up with a fuller battery 
than I started the reboot with (which is also nothing short of impossible).
