How long does the battery last on a curtain robot?

Verified-purchase reviewers and r/HomeKit threads cluster around roughly six months per charge for clip-on curtain robots used a couple of times a day, with solar charging panels (sold separately for SwitchBot, included on the Blind Tilt kit) effectively making the battery a non-issue. Heavy curtains, QuietDrift mode, and many daily cycles all shorten that window.
