Garmin still has to work out some bugs in relation to giving accurate battery estimates when the Heart Rate is off and actually implementing the ♾️ sign for the Solar buildup (when warranted) but I think I just learned the max LUX hours my watch can take before it won’t absorb anymore:
The watch didn’t move and the sun remained consistent, so at least we have a generalized idea of how much can be absorbed (watch was already at 100% when I put it outside).
