The battery percentage is 2464 / 3553 = 69.3%, but the voltage is only 15446 / 4 = 3861.5mV. it’s likely you haven’t charge to 100% and the charging percentage has drifted away. Disable the charge limit in BIOS(or ectool )and charge to 100% and keep it charged for another 2 or 3 hours after reaching 100%
