Hi all,

Are you sure the chip reports current state of charge relative to the
full design capacity rather than to the latest auto-calibrated full
capacity? That would mean that over time as the cells wear out
cw_bat->soc (PROP_CAPACITY) is never going to be reaching 100; does
this match your experience?

As far as I'm aware the gauge reports SoC relative to what it believes 
to be the the current, auto-calibrated full battery capacity.
However, since I don't know how to extract that value from the gauge we 
just always assume it to be the design capacity [1].
Since we inquire the gauge about current SoC directly [2] there is no 
way for any miscalculation on our end preventing it from reaching 100%.

Cheers,
Tobias
