Are battery-powered smart shades reliable, or should I get hardwired?

Across r/smarthome and r/homeautomation threads in the signal set, owners report rechargeable-motor shades running 4–6 months per charge, with solar trickle-charge panels extending that further. Hardwired is still the gold standard for set-and-forget reliability (Lutron Serena is repeatedly named in those threads as the premium benchmark), but USB-C and solar options have closed the gap for most rooms.
