> There's also some suggestions out there that leaving a lithium ion battery fully charged will degrade its max capacity over time; I haven't seen any evidence of that in practice,

I did. Several old devices of mine died like that.

At higher voltages the passivation layer at the cathode, necessary for the battery to function, becomes unstable and decomposes.
