Comment(by werner):
Unfortunately, since this is also the charging cut-off voltage,
there's not a lot of room for increase. With 4.2V, we're already
at the standard charge parameters of the cell (looking at the GTA01
cell's datasheet here). Hearsay has it that the cell won't mind
another 50-100mV, though ... (worst case should be that we trip
the protection circuit)
For an accurate "never let it drain below X%" rule, we probably
need the coulomb counter. So it sounds like a user space problem
after all :-)
