A mobile device for avoiding accidental shutdown includes a battery cell, a controller, and a jack element. The controller defines a first delay time and a second delay time. The first delay time is relative to the ODCP (Over Discharge Current Protection) of the battery cell. The second delay time is relative to the OVP (Over Voltage Protection) of the battery cell. When a plug of a power supply device is unplugged from the jack element, the controller detects an SOH (State of Health) of the battery cell. The controller compares the SOH with a first threshold ratio and a second threshold ratio. Then, the controller extends the first delay time and the second delay time according to a first multiplier, a second multiplier, or a third multiplier.
