Methods and apparatus that receive, at a wireless device, power through wire or inductive pad are described. The received power is monitored to back up data from the device to a server in a network through an OTA (over the air) wireless interface. The data is transmitted to the server to back up the data on the device. While backing up the data, whether the power has been removed from the device is determined. The backing up of the data in the device can be terminated automatically and without user request, in response to the determination that the power has been removed.
