Zusammenfassung:In embodiments of battery charging interrupt, a device (102) includes a capacitive touch interface (104), a battery (110), and a charging circuit (108) that charges the battery when the device is coupled to a power supply (114). A touch detection system (106) detects a conductive contact on the capacitive touch interface of the device, and the touch detection system determines a level of noise on the capacitive touch interface. The level of noise may increase due to the conductive contact on the touch interface while charging the battery. A device controller (126) determines a charge level of the battery. The device controller can then interrupt charging the battery when the level of the noise exceeds a noise level threshold (128) and when the charge level of the battery exceeds a minimum charge level.
