What should I do if the power continues to drop after using solar panels? – SwitchBot Help Center

Please try restarting Curtain 4 to see if the battery capacity is updated.
Please confirm that the Curtain 4 firmware and SwitchBot App versions are the latest. Please enter the Curtain4 page in the SwitchBot App, pull down the device page, and view the recent lighting data. In rainy weather, the solar panel's recharged power may be less than the device's power consumption. We recommend that you enable the automatic charging function and adjust the appropriate charging position to avoid obstruction by window trims, window edges or gauze curtains, so that the solar panel can receive as much light as possible.
The solar panel of Curtain 4 has an adjustable angle function. By pressing the adjustment button on the side of the solar panel, you can adjust the angle of the solar panel according to seasonal changes to receive as much light as possible.
