After just a few days, you get a much more useful forecast than a percentage alone — especially with the complication enabled. IMPORTANT Accuracy improves with regular use. Measurements happen in 5% steps; exact battery readings are limited by the system, so updates may feel slightly delayed. Questions or feedback? Use App Support.
